As a further improvement to the above embodiment, the anti-pull-bias column 6 is movably connected in the anti-pull-bias column hole 7; in the first state, the first end of the anti-pull-off column 6 protrudes out of the first box body, the second end is positioned in the anti-pull-off column hole 7, and the second limiting block 73 is abutted with the closed end of the second limiting groove 63; in the second state, the second end of the pull-proof pillar 6 protrudes out of the first box body, the first end is located in the pull-proof pillar hole 7, and the first limit block 72 abuts against the closed end of the first limit groove 62. That is, the deviation preventing column 6 can move in the longitudinal direction of the deviation preventing column hole 7, but cannot be detached from the deviation preventing column hole 7.

Referring to fig. 11 and 13, as a further improvement of the above embodiment, the lock body transmission member further includes a first transmission rod 91 and a second transmission rod 92, the first transmission rack 4 is detachably and fixedly connected with the first transmission rod 91, the second transmission rack 5 is detachably and fixedly connected with the second transmission rod 92, and the first transmission rod 91 and the second transmission rod 92 have the same size and structure, so that the first transmission rod 91 and the second transmission rod 92 can be used in common, the number of parts is further reduced, and various disadvantages caused by excessive parts are avoided.

Referring to fig. 11 and 13, as a further improvement to the above embodiment, the lock body transmission member further includes a first transmission rod 91 and a second transmission rod 92, the inner side of the first transmission rack 4 is provided with a first catching groove 401 and a first guide groove 402, it should be noted that the inner side refers to a side close to the second transmission rack 5, the inner side of the second transmission rack 5 is provided with a second catching groove 501 and a second guide groove 502, and the inner side refers to a side close to the first transmission rack 4. The first clamping groove 401 is communicated with the second guide groove 502, the second clamping groove 501 is communicated with the first guide groove 401, the outer surfaces of the first transmission rod 91 and the second transmission rod 92 are flush with the outer surfaces of the first transmission gear 4 and the second transmission gear 5, namely, the surfaces of the first transmission rod 91, the second transmission rod 92, the first transmission gear 4 and the second transmission gear 5 far away from the power gear 2 are flush with each other. The first clamping groove 401 and the second clamping groove 501 are identical in size and structure, the first guide groove 402 and the second guide groove 502 are identical in size and structure, in addition, the first clamping groove 401, the first guide groove 402, the second clamping groove 501 and the second guide groove 502 are not groove bodies with side walls on all sides, and the first transmission rack 4 and the second transmission rack 5 are arranged close to each other. The first transmission rod 91 is provided with a first clamping block 911 matched with the first clamping groove 401 and a first guide block 912 matched with the second guide groove 502; the second transmission rod 92 is provided with a second clamping block 921 matched with the second clamping groove 501 and a second transmission block 922 matched with the first transmission groove 402. The first transmission rack 4 drives the first transmission rod 91 to move along the second guide groove 922, and the second transmission rack 5 drives the second transmission rod 92 to move along the first guide groove 912. Furthermore, the first transmission rod 91 and the second transmission rod 92 have the same size and structure, and are only arranged in opposite directions, so that the first transmission rod 91 and the second transmission rod 92 can be used commonly, the number of parts is further reduced, and various disadvantages caused by excessive parts are avoided.

Referring to fig. 4, as a further improvement to the above embodiment, the middle of the power gear 2 is provided with a shaft hole 21, and the shaft hole 21 penetrates through the rotating shaft, when in use, the square shaft of the handle is inserted into the shaft hole 21, and an external force (manual force) twists the handle to drive the power gear 2 to rotate. The hole wall of the shaft hole 21 is a convex arc wall 211 with a middle part protruding and two open ends extending in the direction far away from the hole shaft. The both ends of shaft hole 21 are big middle little, and the longitudinal section in shaft hole 21 is middle shrink, and both ends are the curved surface of horn mouth, and the square shaft inserts in the shaft hole 21 back, can allow the error deflection that has certain installation angle when the square shaft rotates. When transmission square shaft and shaft hole 21 decentraction, along with the rotation of square shaft, the square shaft carries out the swing of certain angle for shaft hole 21, and then can reduce the problem that the execution hand (hold) is smooth and easy when rotating.

As a further improvement to the above embodiment, the power gear 2 is a sector gear, and it should be noted that in this application, the sector gear refers to a gear that is not a complete gear but rather a gear with 180 ° meshing teeth 51, and the meshing teeth 51 of the sector gear may be 180 °, 150 °, 250 °, or the like. Because the displacement of the first transmission rack 4 and the second transmission rack 5 does not need to be too large in practical use, and the practical use area of the power gear 2 is only a part of the gear of the power gear, the driving gear is arranged into a sector gear, the use of the transmission box is not influenced, and the width of the transmission box can be reduced.

As a further improvement to the above embodiment, a baffle is arranged in the middle of the power gear, and the transmission gear and the first transmission rack are respectively meshed and connected to two sides of the baffle, so that mutual influence between the transmission gear and the first transmission rack is reduced.

Referring to fig. 1, as a further improvement to the above embodiment, the lock body transmission member further includes a sliding plate 8, a sliding groove 81 is formed in the sliding plate 8, the first transmission rack 4 and the second transmission rack 5 are slidably connected in the sliding groove 81, a fixing hole is formed in the sliding plate 8, a waterproof member 82 covers the fixing hole, when in use, the sliding plate 8 is fixed with an external closing device body through a bolt or a fixing nail, and the waterproof member 82 seals the bolt or the fixing nail, so as to achieve waterproof, antirust and aesthetic effects. The lock body transmission part also comprises a clamping part, the clamping part is fixedly connected with the transmission rack, the clamping part is fixed on the transmission rack through a fixing nail, and can be directly or indirectly fixed on the transmission rack, and the clamping part can rotate around the fixing nail. When the sealing device is used, the clamping piece is clamped and fixed with the external clamping piece, so that the sealing device can be sealed.

The invention also provides a sealing device which comprises a sealing device body and any one of the lock body transmission pieces, wherein the lock body transmission piece is fixedly connected to the sealing device body. The enclosure body may be a window, a door, a cabinet door or a gas object with similar function.

When the lock body transmission part and the closing device change the center distance of the handle, the lock body transmission part and the closing device can be realized only by changing the widths of the fixing part, the first transmission rack and the second transmission rack, the power gear and the transmission gear do not need to be changed, the universality is strong, and the production is convenient. The existing lock body transmission box is difficult to realize platformization, the development cost is high, a single transmission gear is insufficient in transmission power output torque, transmission is not smooth, the application adopts double transmission gears to enable transmission to be smoother, and the platformization degree of a product is high.
