    Description

    TECHNICAL FIELD



    [0001] The present invention relates to a magnetic unlocking device and a magnetic unlocking structure of a magnetic encoding key.

    BACKGROUND



    [0002] In the industries (such as the electricity, the petrochemistry, the transportation, the metallurgy, the coal and so on), it is a common method of equipment management to lock the door of the equipment and the manual operating mechanism using the lockset. Using a key to operate the lockset is a common method of equipment management, and security arrangement which is essential to avoid accidental risk. Nowadays, the lockset for locking is the ordinary lockset available in the market primarily. Such kind of lockset usually encompasses the lock core with the structure of "bullet-spring" or "bland". Such structure has significant defects if applied in industries. The defects are mainly reflected in terms of reliability. (a) Due to the incomplete rain-proof structure, the parts of the lock core are easily prone to rust. Such phenomenon is especially observed in the oceanic climate, acid rain climate, or the environment which may induce an electrochemical reaction. (b) Since the unlocking hole does not have the dustproof structure, under the condition of a sandstorm, the dust can enter the lock core through the unlocking hole easily, which makes it impossible to open the lock. With respect to this problem, people tried to develop new lockset structure to deal with the above defects. For example, the intention patent whose number is ZL201410107543.3 filed by the present applicant previously and which is titled as a lock core structure with a magnetic encoding free monad style. As shown in Figure 1, the lock core structure includes lock core casing 101, lock knob 104 which is rotatably provided in the internal cavity of lock core casing 101, lock core front end cover 102 and lock core rear end cover 103 that are located at both ends of lock core casing 101. The internal wall of the lock core casing 101 is provided with at least one monad longitudinal moving groove and at least one monad horizontal rotating groove. The end that corresponds to lock core front end cover 102 along the axis line on the lock knob 104 is provided with the unlocking hole of the magnetic encoding key. The external wall of the lock knob 104 is provided with a plurality of monad longitudinal slide-ways 112. At least one of the plurality of monad longitudinal slide-ways 112 is provided with a free monad. The free monad is big monad 107 and small monad 108. The monad longitudinal slide-ways 112 and the monad longitudinal moving groove corresponds to each other and form a monad moving cavity. When the lock core is in the locking position, at least one big monad 107 is located at a position where the monad moving cavity and the monad horizontal rotating groove stagger with each other, or at least one small monad 108 is partially located in monad longitudinal slide-ways 112. When the lock core is in the unlocking position, the big monad 107 is located at a position where the monad moving cavity and the monad horizontal rotating groove intersect, and small monad 108 is located entirely in monad longitudinal slide-ways 112. The magnetic encoding lock core designed with this structure has the advantages of good security, high reliability, easy digital management, simple structure and process of manufacture, and low cost of production. Conditions of being applied in industries are satisfied. The magnetic encoding key in the prior art cannot open the above lock core structure, which puts forward a higher requirement for the core part of the magnetic encoding key-the magnetic unlocking device. US Patent application US 4228667 A by Herriott Leslie V, US 3942345 A by Sasahara Takashi, and Chinese Patent application CN 102003111 A show the kind of magnetic locks and keys known in the art.

    DETAILED DESCRIPTION



    [0013] As shown in Figure 2, Figure 3, Figure 4, Figure 5, Figure 6, Figure 7, Figure 8, Figure 9, and Figure 10, the magnetic unlocking structure of the present invention includes a lock core device and a magnetic unlocking device which is inserted into and fits the lock core device. The lock core device includes a lock core casing, a lock knob which is rotatably provided in the lock core casing internal cavity, a lock core front end cover and a lock core rear end cover that are located on both ends of the lock core casing. The internal wall of the lock core casing is provided with at least one monad longitudinal moving groove and at least one monad horizontal rotating groove. The end which corresponds to the lock core front end cover along the axis line on the lock knob is provided with an unlocking hole of the magnetic encoding key. The external wall of the lock knob is provided with a plurality of monad longitudinal slide-ways. At least one of the plurality of monad longitudinal slide-ways is provided with a free monad. The free monad is the big mon-ad/and small monad. The monad longitudinal slide-way and the monad longitudinal moving groove correspond to each other and form a monad moving cavity. When the lock core is in a locking position, at least one big monad is located at a position where the monad moving cavity and the monad horizontal rotating groove stagger with each other, or at least one small monad is partially located inside the monad longitudinal slide-way. When the lock core is in an unlocking position, the big monad is located at a position where the monad moving cavity and the monad horizontal rotating groove intersect, and the small monad is entirely located inside the monad longitudinal slide-way. The magnetic unlocking device includes key casing 2 and at least one set of magnetic combination unit and filler 4 that is located inside key casing 2. The shape of the key casing 2 can be round, rectangular, triangular, etc., which is mainly determined by the structure of the preserved unlocking hole in the lock core. Preferably, the round shape is used. Filler 4 is a magnetic conductor or a magnetic non-conductor. Here, filler 4 has the function of supporting and position-limiting. Filler 4 can be molded together with casing 2 of the structure or other parts. The number of the magnetic combination unit is determined according to the number of free terminal moving cavity in the lock core. There are different types of the magnetic combination unit. More accurately, there are three types of the structure. 1, The magnetic combination unit includes one double-pole permanent magnet 6 and magnetic yoke 5. At least one magnetic pole of double-pole permanent magnet 6 is near to magnetic yoke 5. The other magnetic pole is far from magnetic yoke 5. A butterfly-like magnetic field distribution is generated on the external main magnetic circuit of the magnetic combination unit. 2, The magnetic combination unit includes a plurality of double-pole permanent magnets 6. The surface magnetic fluxes of the plurality of double-pole permanent magnets 6 increase or decrease one by one along the arranging orientation. Two adjacent double-pole permanent magnets 6 on the same side have opposite polarities. Magnetic yoke 5 is used as the magnetic conducting path for respective magnetic pole of the plurality of the double-pole permanent magnets 6 oriented to an axial center. The main magnetic circuit passes therethrough. A magnetic field distribution which is weak-to-strong or strong-to-weak along a magnet arranging orientation is generated on the external main magnetic circuit of the magnetic combination unit. 3, The magnetic combination unit includes multi-pole permanent magnet 3 and magnetic yoke 5. The multi-pole permanent magnet 3 is divided into a plurality of magnet units 11 that have opposite polarities. The surface magnetic fluxes of the plurality of the magnet units 11 increase or decrease one by one along the arranging orientation. Adjacent magnet units 11 on the same side have opposite polarities. The magnetic yoke 5 is used as the magnetic conducting path for respective magnetic pole of the multi-pole permanent magnet 3 oriented to the axial center. The main magnetic circuit passes therethrough. A magnetic field distribution which is weak-to-strong or strong-to-weak along a magnet arranging orientation is generated on the external main magnetic circuit of the magnetic combination unit. Magnetic yoke 5 is one of soft iron or magnetic steel or magnetically soft alloy or ferrite material. Magnetic yoke 5 is used as the magnetic conducting path for respective magnetic pole of the multi-pole permanent magnet 3 oriented to an axial center. The main magnetic circuit passes therethrough. A magnetic field distribution which is weak-to-strong or strong-to-weak along a magnet arranging orientation is generated on the external main magnetic circuit of the magnetic combination unit. There can be a plurality sets of magnetic combination units. Some of the magnetic combination units include one or more double-pole permanent magnets 6 and magnetic yoke 5. Remaining magnetic combination units include multi-pole permanent magnet 3 and magnetic yoke 5. The plurality sets of magnetic combination units share the same the magnetic yoke 5. Thus, a part of the main magnetic circuit of the magnetic combination unit is inside the multi-pole permanent magnet 3 and magnetic yoke 5, and a part of the main magnetic circuit passes through key casing 2 entering the external space. The main magnetic field of the magnetic combination unit has an oriented distribution in the external space.

    [0014] According to the convenience of manufacture, the third technical solution is described in detail hereinafter. Take the four-pole permanent magnet as an example, the magnetic combination unit includes one magnet unit 11 with a large surface flux and one magnet unit 11 with a small surface flux. When the multi-pole permanent magnet 3 is expanded into six-pole, the multi-pole permanent magnet 3 includes one magnet unit 11 with a large surface flux, one magnet unit 11 with a middle surface flux, and one magnet unit 11 with a small surface flux that are arranged in sequence. Such design can generate a magnetic field distribution which is weak-to-strong or strong-to-weak along the magnetic steel arranging orientation on the main magnetic circuit outside the magnetic combination unit. Magnet units 11 are made of the same material, having the same intensity of magnetization. The magnets with different surface fluxes are made by altering the area of the cylindrical surface which is perpendicular to the magnetic field.

    [0015] When the magnetic encoding key is inserted into the magnetic encoding lock core and reaches the unlocking position, each set of magnetic combination unit of the magnetic unlocking mechanism in the magnetic encoding key respectively corresponds to one free monad moving cavity in the magnetic encoding lock core in terms of the spatial position one-by-one. The externally oriented distribution of the main magnetic field of the magnetic combination unit is directly oriented to the free monad moving cavity. Thus, the magnetic combination unit and the free monad located inside the free monad moving cavity, which includes big monad 107 and small monad 108, form a flux linkage which has a short magnetic circuit. Further, the free monad is attracted to a position with the shortest magnetic circuit - unlocking position.

    [0016] The content described above is one embodiment of the present invention, which is not used to limit the scope of the present invention. Any equivalent alternatives or modifications according to the present invention are covered by the scope of the claims of the present invention.
