    Description

    BACKGROUND OF THE INVENTION


    1. Field of the Invention



    [0001] The present disclosure relates to a clamping mechanism, more particularly to a clamping mechanism which is able to clamp an industrial input/output device on a DIN rail or unloading the industrial input/output device from the DIN rail by simultaneous actions between mechanism elements.

    2. Description of the Related Art



    [0002] German standardization institute defines a standard stamped metal rail which is called a DIN rail, and the DIN rail is generally used to secure an industrial input/output device.

    [0003] In order to secure the industrial input/output device on the DIN rail, a clamping mechanism must be used to clamp the industrial input/output device. There are different available clamping mechanisms in market.

    [0004] For example, U.S. issued patent, No.6431909, discloses a detachable securement apparatus for a mounting rail. The mounting rail has first and second mounting flanges extending lengthwise along opposite sides of a support section. The apparatus has a body, a securement assembly and a release assembly. Extending from the body, the securement assembly has first and second interface members each including a contact region configured to exert a holding force on the first and second mounting flanges, respectively. The release assembly is configured for removing the holding force on both the first and second mounting flanges to allow vertical removal of the body. The release assembly has an engagement member coupled to the body and to the first and second interface members, and is engagable on a side of the body.

    [0005] However, according to the technology disclosed by U.S. issued patent No.6431909, external tools are required to secure the industrial input/output device on the DIN rail; generally, the DIN rail may have insufficient space for securing the industrial input/output device, so the manner of using the external tools to secure the industrial input/output device on the DIN rail has a problem of inconvenient operation.

    [0006] WO 2004/114466 A1 teaches a detachable securement apparatus for a mounting rail, wherein the mounting rail has first and second mounting flanges extending lengthwise along opposite sides of a support section. The apparatus has a body, a securement assembly and a release assembly. Extending from the body, the securement assembly has first and second interface members each including a contact region configured to exert a holding force on the first and second mounting flanges, respectively. The release assembly is configured for removing the holding force on both the first and second mounting flanges to allow vertical removal of the body. The release assembly has an engagement member coupled to the body and to the first and second interface members, and is engagable on a side of the body. A method of attachment and detachment with flanges of a rail mount assembly includes springably coupling first and second sides of a conductive mounting member to the first and second flange, laterally engaging a release actuator coupled to the mounting members, and simultaneously releasing the first and second sides of the mounting member from the flanges.

    [0007] To summarize, the conventional technology has the problem that the industrial input/output device cannot be secured on the DIN rail conveniently. Therefore, what is need is to develop a clamping device to solve the problem.

    [0019] Please refer to FIG. 2, which is a plan view of a mechanism assembly of the clamping mechanism for the industrial input/output device, in accordance with the first embodiment mode of the present disclosure.

    [0020] As shown in FIG. 2, an operating link 20 includes a pivot pin 21, a rod sliding slot 22, a first operating part 23 and a second operating part 24. The operating link 20 is disposed in the sliding track 11 of the shell member 10 by the pivot pin 21, and is slidable and rotatable relative to the sliding track 11 of the shell member 10. The first operating part 23 and the second operating part 24 are exposed out of the shell member 10. The rod sliding slot 22 includes a first sliding slot end 221 and a second sliding slot end 222.

    [0021] It should be noted that the first operating part 23 of the operating link 20 has a surface in a wave shape to increase friction thereof, so that the first operating part 23 of the operating link 20 may be operated more easily.

    [0022] A first clamping rod 30 is disposed in the mechanism assembly receiving space 12 of the shell member 10, and includes a first driving part 31, an elastic element mounting part 32, a first clamping part 33 and a second driving part 34. The first driving part 31 of the first clamping rod 30 is disposed in the rod sliding slot 22 of the operating link 20, so that the first driving part 31 of the first clamping rod 30 is slidable relative to the rod sliding slot 22 of the operating link 20. A part of the first clamping part 33 of the first clamping rod 30 is exposed out of the shell member 10, and the exposed part of the first clamping part 33 is configured to clamp the industrial input/output device on the DIN rail.

    [0023] The elastic element mounting part 32 of the first clamping rod 30 is configured to secure an elastic element 40 in the mechanism assembly receiving space 12 of the shell member 10, and the elastic element 40 is configured to provide a clamping force to enable the first clamping rod 30 to clamp the industrial input/output device on the DIN rail.

    [0024] A rotary rod 50 is pivotally disposed in the mechanism assembly receiving space 12 of the shell member 10, and includes a first rotary driving part 51 and a second rotary driving part 52. The second driving part 34 of the first clamping rod 30 is assembled with the first rotary driving part 51 of the rotary rod 50, so that the rotary rod 50 may be driven to rotate by movement of the first clamping rod 30.

    [0025] A second clamping rod 60 is disposed in the mechanism assembly receiving space 12 of the shell member 10, and includes a third driving part 61 and a second clamping part 62. The third driving part 61 of the second clamping rod 60 is assembled with the second rotary driving part 52 of the rotary rod 50, so that the second clamping rod 60 may be driven to move by rotation of the rotary rod 50. A part of the second clamping part 62 of the second clamping rod 60 is exposed out of the shell member 10, and the exposed part of the second clamping part 62 is used to clamp the industrial input/output device on the DIN rail.

    [0026] Please refer to FIGs. 3A through 3C, which are plan views showing a process of operating the clamping mechanism for the industrial input/output device, in accordance with the first embodiment mode of the present disclosure.

    [0027] FIG. 3A shows a default state of the clamping mechanism for the industrial input/output device. In the default state, the pivot pin 21 of the operating link 20 is located at the first sliding track end 111 of the sliding track 11, and the first driving part 31 of the first clamping rod 30 is located at the second sliding slot end 222 of the rod sliding slot 22, and at this time, the operating link 20 is unable to rotate relative to the shell member 10, and the first clamping part 33 of the first clamping rod 30 is forced by the downward elastic force of the elastic element 40 to expose the part thereof out of the shell member 10, and the second clamping part 62 of the second clamping rod 60 acts simultaneously with the first clamping part 33 of the first clamping rod 30 to expose the part thereof out of the shell member 10, so that the downward elastic force of the elastic element 40 enables the first clamping part 33 of the first clamping rod 30 and the second clamping part 62 of the second clamping rod 60 to clamp the industrial input/output device on the DIN rail.

    [0028] In order to clamp the industrial input/output device on the DIN rail or unload the industrial input/output device from the DIN rail, the first operating part 23 of the operating link 20 can be operated to push or pull the operating link 20 out of the shell member 10, as shown in FIG. 3B; and at this time, the pivot pin 21 of the operating link 20 is also moved to the second sliding track end 112 of the sliding track 11 and the first driving part 31 of the first clamping rod 30 is moved to the first sliding slot end 221 of the rod sliding slot 22, thereby making the operating link 20 rotatable relative to the shell member 10.

    [0029] Next, as shown in FIG. 3C, the second operating part 24 of the operating link 20 can be pressed down to rotate the operating link 20 clockwise relative to the shell member 10, so that the first clamping rod 30 is driven by the first driving part 31 of the first clamping rod 30 to move upwardly and the first clamping part 33 of the first clamping rod 30 is also upwardly moved into the shell member 10. By upwardly moving the second driving part 34 of the first clamping rod 30 to clockwise rotate the rotary rod 30, the second clamping rod 60 can be moved downwardly to drive the second clamping part 62 of the second clamping rod 60 to move into the shell member 10, so that the industrial input/output device can be clamped on the DIN rail or unloaded from the DIN rail.

    [0030] After the second operating part 24 of the operating link 20 is stopped pressing down, the downward elastic force of the elastic element 40 can push the first clamping rod 30 to move downwardly, to expose the part of the first clamping part 33 of the first clamping rod 30 out of the shell member 10; next, the first driving part 31 of the first clamping rod 30 can be moved downwardly to drive the operating link 20 to counter-clockwise rotate, and the second driving part 34 of the first clamping rod 30 can be moved downwardly to drive the rotary rod 30 to counter-clockwise rotate, so as to drive the second clamping rod 60 to move upwardly to expose the part of the second clamping part 62 out of the shell member 10. As a result, while be exerted by the downward elastic force of the elastic element 40, the first clamping part 33 of the first clamping rod 30 and the second clamping part 62 of the second clamping rod 60 can clamp the industrial input/output device on the DIN rail, as shown in FIG. 3B.

    [0031] Next, the first operating part 23 of the operating link 20 is operated to push the operating link 20 into the shell member 10, and at this time, the pivot pin 21 of the operating link 20 is moved to the first sliding track end 111 of the sliding track 11, and the first driving part 31 of the first clamping rod 30 is moved to the second sliding slot end 222 of the rod sliding slot 22, so that the operating link 20 is unable to rotate relative to the shell member 10.

    [0032] Preferably, the shell member 10, the operating link 20, the first clamping rod 30, the elastic element 40, the rotary rod 50 and the second clamping rod 60 are made of metal material or polymer material; for example, the metal material may be iron, steel or aluminum alloy, the polymer material may be polyethylene (PE), polyvinyl chloride (PVC) or polypropylene (PP), but the application field of the present disclosure is not limited to these examples merely for illustration.

    [0033] The following illustrates the clamping mechanism for the industrial input/output device, in accordance with a second embodiment mode of the present disclosure.

    [0034] Please refer to FIG. 4, which is a plan view of the interior of a shell member of a clamping mechanism for an industrial input/output device, in accordance with a second embodiment mode of the present disclosure.

    [0035] The shell member 10 includes a sliding track 11 disposed at a top side thereof and a mechanism assembly receiving space 12 at a rear side thereof.

    [0036] Please refer to FIG. 5, which is a plan view of a mechanism assembly of the clamping mechanism for the industrial input/output device, in accordance with the second embodiment mode of the present disclosure.

    [0037] A first operating link 70 includes a first operating part 71 which is exposed out of the shell member 10 and disposed on the sliding track 11 of the shell member 10, so that the first operating link 70 is slidable along the sliding track 11 of the shell member 10.

    [0038] A second operating link 80 includes a second operating part 81 which is exposed out of the shell member 10. The second operating link 80 is pivotally connected with the top side of the shell member 10. The first operating link 70 can be pushed or pulled out of the shell member 10 to release the constraint for rotation of the second operating link 80, that is, when the first operating link 70 is pushed out of the shell member 10, the second operating link 80 becomes rotatable relative to the shell member 10, and when the first operating link 70 is inserted into the shell member 10, the second operating link 80 becomes non-rotatable relative to the shell member 10.

    [0039] The first clamping rod 30 is disposed in the mechanism assembly receiving space 12 of the shell member 10, and the first clamping rod 30 includes a first driving part 31, an elastic element mounting part 32, a first clamping part 33 and a second driving part 34. The first driving part 31 of the first clamping rod 30 is pivotally connected to the operating link 80, so that the first driving part 31 of the first clamping rod 30 can be driven to move by the operating link 80. A part of the first clamping part 33 of the first clamping rod 30 is exposed out of the shell member 10, and the exposed part of the first clamping part 33 of the first clamping rod 30 is used to clamp the industrial input/output device on the DIN rail.

    [0040] An elastic element 40 is secured in the mechanism assembly receiving space 12 of the shell member 10 by the elastic element mounting part 32 of the first clamping rod 30, and configured to provide a clamping force to enable the first clamping rod 30 to clamp the industrial input/output device on the DIN rail.

    [0041] The rotary rod 50 is pivotally disposed in the mechanism assembly receiving space 12 of the shell member 10, and includes a first rotary driving part 51 and a second rotary driving part 52. The second driving part 34 of the first clamping rod 30 is assembled with the first rotary driving part 51 of the rotary rod 50, so that the rotary rod 50 can be driven to rotate by the movement of the first clamping rod 30.

    [0042] The second clamping rod 60 is disposed in the mechanism assembly receiving space 12 of the shell member 10, and includes a third driving part 61 and a second clamping part 62. The third driving part 61 of the second clamping rod 60 is assembled with the second rotary driving part 52 of the rotary rod 50, so that the second clamping rod 60 can be driven to move by rotation of the rotary rod 50. A part of the second clamping part 62 of the second clamping rod 60 is exposed out of the shell member 10, and the exposed part of the second clamping part 62 is used to clamp the industrial input/output device on the DIN rail.

    [0043] Please refer to FIGs. 6A-6C, which are plan views showing a process of operating the clamping mechanism for the industrial input/output device, in accordance with the second embodiment mode of the present disclosure.

    [0044] FIG. 6A shows a default state of the clamping mechanism for the industrial input/output device. In the default state, the first operating link 70 is inserted in the shell member 10, and the second operating link 80 is non-rotatable subject to constraint of the first operating link 70. The elastic element 40 exerts downward elastic force on the first clamping part 33 to expose the part of the first clamping part 33 of the first clamping rod 30 out of the shell member 10; at the same time, the part of the second clamping part 62 of the second clamping rod 60 is also exposed out of the shell member 10 because of linking relationship of entire mechanism. As a result, while being exerted by the downward elastic force of the elastic element 40, the first clamping part 33 of the first clamping rod 30 and the second clamping part 62 of the second clamping rod 60 can clamp the industrial input/output device on the DIN rail.

    [0045] Please refer to FIG. 6B. In order to clamp the industrial input/output device on the DIN rail or unload the industrial input/output device from the DIN rail, the first operating part 71 of the first operating link 70 can be operated to push or pull the first operating link 70 out of the shell member 10, thereby releasing the constraint for rotation of the second operating link 80.

    [0046] Please refer to FIG. 6C. When the second operating part 81 of the second operating link 80 is pressed down, the second operating link 80 is rotated clockwise relative to the shell member 10, and the first driving part 31 of the first clamping rod 30 drives the first clamping rod 30 to move upwardly, so that the first clamping part 33 of the first clamping rod 30 is moved into the shell member 10. By upwardly moving the second driving part 34 of the first clamping rod 30 to drive clockwise rotation of the rotary rod 30 to move the second clamping rod 60 downwardly, the second clamping part 62 of the second clamping rod 60 can be moved into the shell member 10, thereby clamping the industrial input/output device on the DIN rail or unloading the industrial input/output device from the DIN rail.

    [0047] After the second operating part 81 of the second operating link 80 is stopped pressing down, the first clamping rod 30 is pushed to move downwardly by the downward elastic force of the elastic element 40, so as to expose the part of the first clamping part 33 of the first clamping rod 30 out of the shell member 10, and at this time, the second operating link 80 is counter-clockwise rotated by downward movement of the first driving part 31 of the first clamping rod 30. When the second driving part 34 of the first clamping rod 30 is moved downwardly to drive the rotary rod 50 to counter-clockwise rotate, the second clamping rod 60 can be driven to move upwardly to expose the part of the second clamping part 62 out of the shell member 10. Subject to the downward elastic force of the elastic element 40, the first clamping part 33 of the first clamping rod 30 and the second clamping part 62 of the second clamping rod 60 can clamp the industrial input/output device on the DIN rail, as shown in FIG. 6B.

    [0048] Next, the first operating part 71 of the first operating link 70 can be operated to insert the first operating link 70 into the shell member 10, so that the first operating link 70 can limit rotation of the second operating link 80, that is, the second operating link 80 is unable to rotate relative to the shell member 10.

    [0049] Preferably, the shell member 10, the first operating link 70, the second operating link 80, the first clamping rod 30, the elastic element 40, the rotary rod 50 and the second clamping rod 60 are made of metal material or polymer material, and for example, the metal material may be iron, steel, or aluminum alloy; the polymer material may be polyethylene, polyvinyl chloride, or polypropylene, but the application field of the present disclosure is not limited to these examples which are merely for exemplary illustration.

    [0050] To summarize, the difference between the present disclosure and the conventional technology is that the operating link of the clamping mechanism of the present disclosure can be slid and rotated to drive links of the mechanism gearings disposed inside the shell member to act simultaneously, thereby clamping the industrial input/output device on the DIN rail or unloading the industrial input/output device from the DIN rail conveniently and fast.

    [0051] The technical means of the present disclosure can solve the conventional technology problem that it is inconvenient to secure the industrial input/output device on the DIN rail, and further achieve the technical effect of clamping the industrial input/output device on the DIN rail or unloading the industrial input/output device from the DIN rail fast and conveniently.

    [0052] The present disclosure disclosed herein has been described by means of specific embodiments. However, numerous modifications, variations and enhancements can be made thereto by those skilled in the art without departing from the scope of the invention set forth in the claims.
