[0024] The connecting sleeve 40 is provided with a limiting groove 44, the key main body 20 is provided with a limiting rib 23, and the limiting groove 44 and the limiting rib 23 are in limiting fit with each other, so that the connecting sleeve 40 and the key main body 20 synchronously rotate.

[0025] As shown in Fig.5, the key seat 32 is provided with a non-circular hole 322, the compression bar 50 is provided with a non-circular cooperation portion 52 corresponding to the non-circular hole 322 of the key seat 32, and the compression bar 50 is in circumferential limiting fit with the key seat 32 through the non-circular hole 322 and the non-circular cooperation portion 52.

[0026] Specifically, in one embodiment, the non-circular hole 322 is a straight hole, and the non-circular cooperation portion 52 is a straight clamping strip, so that the structure is simple, the assembly is convenient, the circumferential limiting of the compression bar 50 on the key seat 32 can also be achieved by using other non-circular structure, and is not limited thereto.

[0027] In order to conveniently insert the compression bar 50 into the non-circular hole 32, the compression bar 50 is provided with a guiding inclined plane 53 for facilitating the insertion of the compression bar 50 into the non-circular hole 322, and a guiding inclined plane 323 for facilitating the insertion of the compression bar 50 into the non-circular hole 322 is also arranged on the inner wall of the non-circular hole 322 of the key seat 32, the guiding inclined plane 53 on the compression bar 50 and the guiding inclined plane 323 on the key seat 32 cooperate with each other for guiding. Alternatively, only the guiding inclined plane 53 is arranged on the compression bar 50, or, only the guiding inclined plane 323 is arranged on the key seat 32, the function of facilitating the insertion of the compression bar 50 into the non-circular hole 322 would also be achieved.

[0028] As shown in Fig.2 and Fig.3, in the embodiment, a threaded pipe 22 is arranged at the bottom of the key main body 20, and the connecting sleeve 40 is sleeved in the threaded pipe 22 and forms circumferential limiting with the threaded pipe 22. The bracket 11 is provided with a nut 12, the nut 12 is in threaded connection with the key main body 20, the compression bar 50 is arranged on the nut 12 in the circumferential limiting manner, and the pitches of the threads on the nut 12, the key main body 20, the compression bar 50 and the connecting sleeve 40 are equal, so that the threaded connection between the key main body 20 and the nut 12 generates no mutual interference with the threaded connection between the compression bar 50 and the connecting sleeve 40. Specifically, the threaded pipe 22 is provided with a first external thread 221, the nut 12 is provided with a first internal thread 121, the compression bar 50 is provided with a second external thread 51, the connecting sleeve 40 is provided with a second internal thread 42, and the pitches of the first external thread 221, the first internal thread 121, the second external thread 51 and the second internal thread 42 are all equal.

[0029] In addition, a sliding slot 13 is formed in the top of the bracket 11, a sliding plate 14 is slidably installed in the sliding slot 13 along a first direction, the nut 12 is slidably installed on the sliding plate 14 along a second direction, and the first direction is perpendicular to the second direction. In this way, the position of the nut 12 on the bracket 11 is adjustable within a certain range to adapt to the position of the key main body 20. Accordingly, the requirements of size matching can be significantly reduced, the assembly is convenient, and the suitability is better. The bracket 11 includes two connecting arms 15, the two connecting arms 15 are installed on both sides of the drain valve 10 in a height adjustable manner. A pressing plate 54 is arranged at the bottom of the compression bar 50, the pressing plate 54 cooperates with a lifting rod 16 that is rotatably arranged on the drain valve 10. When the pressing plate 54 presses one end of the lifting rod 16, the other end of the lifting rod 16 tilts and lifts a sealing component of the drain valve 10 to open the drain valve.

[0030] As shown in Fig.2 and Fig.4, in the embodiment, the key 31 includes a full-row key 311 and a semi-row key 312, the full-row key 311 is fixedly installed on the key seat 32, the semi-row key 312 is movably installed on the key seat 32. A stroke of the full-row key 311 for driving the key seat 32 to move when being driven is greater than the stroke of the semi-row key 312 for driving the key seat 32 to move when being driven, the drain valve button bracket further includes a first elastic member 33 for resetting the key component, and the first elastic member 33 comprises pressure spring. In the embodiment, the full-row key 311 and the semi-row key 312 are both installed on the key seat 32. When the full-row key 311 is pressed, the movement stroke of the key seat 32 is longer, and the key seat 32 drives the compression bar 50 to move along the axial direction via the connecting sleeve 40 to drive a sealing component of the drain valve 10 to move upward for a relatively longer stroke to achieve full drainage; and when the semi-row key 312 is pressed, the movement stroke of the key seat 32 is shorter, the key seat 32 drives the compression bar 50 to move along the axial direction via the connecting sleeve 40 to drive the sealing component of the drain valve 10 to move upward for a relatively shorter stroke to achieve semi-drainage.

[0031] The assembly process in the present embodiment is as follows:
Firstly, the connecting arms 15 of the bracket 11 are inserted on the valve body of the drain valve 10, the sliding plate 14 is inserted into the sliding slot 13 in the top of the bracket 11, then the nut 12 is installed on the sliding plate 14, then the compression bar 50 is installed on the nut 12, the compression bar 50 is slidable relative to the nut 12 on the axial direction and forms limiting fit with the nut 12 on the circumferential direction. Since the sliding plate 14 only slides in the sliding slot 13 and cannot rotate along the circumferential direction, and the nut 12 can only slide on the sliding plate 14 and cannot rotate along the circumferential direction, the bracket 11 performs circumferential limiting on the compression bar 50. Accordingly, the assembly process of the compression bar 50, the nut 12, the sliding plate 14 and the bracket 11 is completed.

[0032] Secondly, the full-row key 311 and the semi-row key 312 are installed on the key seat 32, after the first elastic member 33 is sleeved on the key seat 32, the key seat 32 is installed in the accommodating cavity 21 of the key main body 20, then the connecting sleeve 40 is sleeved in the threaded pipe 22 upward from the bottom end of the threaded pipe 22, the buckle 41 on the top end of the connecting sleeve 40 abuts against the annular groove 321 on the key seat 32. Under the action of the first elastic member 33, the key seat 32 pulls the connecting sleeve 40 upward, so that a flange 45 arranged at the bottom end of the connecting sleeve 40 abuts against a bottom end face of the threaded pipe 22, and accordingly the assembly process of the key main body 20, the key component and the connecting sleeve is completed.

[0033] Finally, the key main body 20 is placed on a mounting hole of a water tank cover of a toilet (not shown in the figures), the connecting arms 15 can slide up and down to adjust the height of the bracket 11, the threaded pipe of the key main body 20 is aligned and contact with the nut 12. At this time, under the guiding of the guiding inclined plane 53 and the guiding inclined plane 323, the straight clamping strip 52 of the compression bar 50 automatically aligns and is inserted into the straight hole 322 of the key seat 32, the key main body 20 is threadedly connected with the nut 12 by rotating the key main body 20, while the key main body 20 is in threaded connection with the nut 12, the connecting sleeve 40 is also in threaded connection with the compression bar 50, until the key main body 20 and the nut 12 lock the water tank cover, and accordingly the assembly of the button bracket is completed.

[0034] It should be noted that, the threaded connection between the connecting sleeve 40 and the compression bar 50 does not needs to be performed with the threaded connection between the key main body 20 and the nut 12, and the threaded connection between the connecting sleeve 40 and the compression bar 50 would be performed before or after the threaded connection between the key main body 20 and the nut 12.

Second embodiment:

[0035] As shown in Fig.6 to Fig.9, the main difference between the second embodiment and the first embodiment lies in that: the key 31 includes a full-row key 311 and a semi-row key 312, the key seat 32 includes a full-row buckle seat 34 fixedly connected with the full-row key 311, a semi-row buckle seat 35 fixedly connected with the semi-row key 312, and a rotation stop seat 36 rotatably connected with the connecting sleeve 40, the compression bar 50 is in circumferential limiting fit with the rotation stop seat 36, and the full-row buckle seat 34 and the semi-row buckle seat 35 are both in axial sliding fit and circumferential limiting fit with the rotation stop seat 36. In the first embodiment, since the full-row key 311 is fixed to the key seat 32, when the semi-row key 312 is pressed, the full-row key 311 is driven to move together. The full-row key 311 and the semi-row key 312 would move independent of each other in the second embodiment, the rotation stop seat 36 could be driven to rotate by pressing the full-row key 311 or the semi-row key 312, then the rotation stop seat 36 drives the connecting sleeve 40 to move, and the connecting sleeve 40 drives the compression bar 50 to move so as to activate the drain valve. Since the semi-row key 312 is not driven when the full-row key 311 is pressed, or, the full-row key 311 is not driven when the semi-row key 312 is pressed, full-drainage and semi-drainage can be distinguished more easily, and the operation is more visual.

[0036] In addition, the present embodiment further includes a carrying tray 60, the carrying tray 60 is rotatably arranged in the accommodating cavity 21 of the key main body 20 relative to the key main body 20, the full-row buckle seat 34 and the semi-row buckle seat 35 are slidably installed on the carrying tray 60, the drain valve button bracket further includes a second elastic member 341, a third elastic member 351 and a fourth elastic member 361 for respectively resetting the full-row buckle seat 34, the semi-row buckle seat 35 and the rotation stop seat 36, and the second elastic member 341, the third elastic member 351 and the fourth elastic member 361 comprise pressure springs.

[0037] Furthermore, the key main body 20 is separately connected with the threaded pipe 22, and the threaded pipe 22 is connected to the bottom of the key main body 20. The annular groove 321 of the key seat 32 is formed in the rotation stop seat 36, and the buckle 41 of the connecting sleeve 40 cooperates with the annular groove 321 in the rotation stop seat 36. The limiting groove 44 is formed in the connecting sleeve 40, the limiting rib 23 is arranged on the inner wall of the threaded pipe 22, and the limiting groove 44 and the limiting rib 23 are in limiting fit with each other, so that the connecting sleeve 40 and the threaded pipe 22 synchronously rotate.

[0038] The application also provides a toilet, which comprises a drain valve and the drain valve button bracket, and the bracket is arranged on the drain valve in a circumferential limiting manner.
