Further, a clamping part is arranged on the first eccentric member 411, the clamping part is used for clamping the first eccentric member 411 and the second eccentric member 441 to enable the lock hook 300 and the lock rod 210 to be in a locking state, the clamping part comprises a unidirectional rotating member and a clamping member, the unidirectional rotating member can be a unidirectional bearing, a clamping key 431 is fixedly arranged on the outer circumferential surface of an outer ring 432 of the unidirectional bearing, a through hole capable of being placed into the unidirectional bearing is formed in the first eccentric member 411, and a clamping groove 413 is formed in the inner surface of the through hole.

When in the second position, the outer latch 422 of the latch is not engaged with the inner latch 434 of the inner ring 433 of the one-way bearing, and the synchronous hexagonal post 423 of the latch is engaged with the inner hexagonal fixed cylinder 442 of the second eccentric member 441, so that the first eccentric member 411 can rotate clockwise and counterclockwise relative to the second eccentric member 441.
When the latch hook 300 is worn, the first eccentric part 411 can rotate clockwise relative to the second eccentric part 441 under the action of the first elastic part 443, so that the influence of the wear of the latch hook 300 is eliminated, when the first eccentric part 411 rotates clockwise relative to the second eccentric part 441, so that the influence of the wear of the latch hook 300 is eliminated, the first eccentric part 411 does not rotate any more, and at the moment, the first eccentric part 411 cannot rotate anticlockwise relative to the second eccentric part 441 so as to lock the two refrigeration house plates again.
Further, a second elastic member 424 is disposed on the bottom surface of the hexagonal synchronization column 423 of the locking member, and the second elastic member 424 may be a return spring, a pneumatic spring, a hydraulic spring, or the like, where one end of the second elastic member 424 is connected to the bottom surface of the hexagonal synchronization column 423 of the locking member, and the other end of the second elastic member 424 is connected to the inner hexagonal fixed cylinder 442 of the second eccentric member 441. In the initial state, the second elastic member 424 is in a relaxed state, so that the engaging member is in the first position, the outer latch 422 of the engaging member is engaged with the inner latch 434 of the inner surface of the unidirectional bearing, at this time, the lock rod 210 and the lock hook 300 are completely engaged, and in the compressed state, the second elastic member 424 is in the second position, the outer latch 422 of the engaging member is not engaged with the inner latch 434 of the inner surface of the unidirectional bearing, at this time, the first eccentric member 411 can rotate relative to the second eccentric member 441.
It will be appreciated that the first eccentric 411 can only rotate clockwise relative to the second eccentric 441 when the return spring is in a relaxed state, and that the first eccentric 411 can rotate clockwise relative to the second eccentric 441 or counter-clockwise relative to the second eccentric 441 when the return spring is in a compressed state.
