The bottom of lock cylinder 42 extends downward to form a striking portion 44 that is inserted into elongated slot 74. it should be noted that striking portion 44 has a diameter that is less than or equal to the slot width of elongated slot 74. The cipher wheel assembly 3 comprises a wheel shaft 31 capable of reciprocating and stretching, and it should be noted that the cipher wheel assembly 3 is of a conventional cipher wheel structure, the cipher is correct, and the wheel shaft 31 can reciprocate and stretch. The end of the axle 31 abuts against the housing 41 of the button assembly 4, and it should be noted that the end of the axle 31 only abuts against the housing 41 and does not abut against the movable member 7, so that when the key is used to unlock the lock, the movable member 7 cannot be unlocked because the axle 31 cannot move during the process of the movable member 7 being moved by the moving portion 44, that is, a gap for the movable member 7 to move exists between the end of the axle 31 and the base plate 14.

In the unlocking process of the code wheel assembly 3, the code is correct, the wheel shaft 31 can do reciprocating telescopic motion, the wheel shaft 31 removes the limitation of the movement of the button assembly 4 towards the unlocking direction, the button assembly 4 is pushed by applying external force, the moving part 7 can be pushed by the poking part 44 of the button assembly 4 to move (from left to right), and the unlocking part 71 of the moving part 7 is matched with the abutting-against effect of the third wedge-shaped surface 67 and the fourth wedge-shaped surface 76, so that the two locking block bodies 6 are opened, and the unlocking is realized. In the locking process, the spring 22 drives the two locking block bodies 6 to fold by using the elasticity of the spring 22, the third wedge-shaped surface 67 reversely extrudes the fourth wedge-shaped surface 76 by using the elasticity of the spring 22 to return the movable member 7, then the wheel shaft 31 drives the button assembly 4 to move to the maximum stroke position under the elastic action of the elastic member of the password wheel assembly 3, and the password is disordered, so that the locking is completed.

When the lock core 42 is unlocked, a key is inserted and the lock core 42 is rotated, the stirring portion 44 of the lock core 42 also rotates along with the key, the stirring portion 44 can abut against the long groove 74, the movable part 7 is limited by the lock shell due to the fact that the movable part 7 moves left and right, the movable part 7 can only move in the unlocking direction, the movable part 7 moves in the unlocking direction, the rotation of the lock core 42 can be converted into the movement of the movable part 7 in the direction opposite to the two lock block bodies 6 (the unlocking direction is shown in the figure 5 from left to right), and the unlocking portion 71 of the movable part 7 opens the two lock block bodies 6 to achieve unlocking. In the locking process, the lock core 42 is rotated, and the elastic force of the spring 22 reversely extrudes the movable piece 7 to return, so that locking is realized.

In order to further improve the unlocking manner of the zipper combination lock, referring to fig. 8, the unlocking mechanism includes a rotating motor 9, the output end of the rotating motor 9 is provided with a rotatable long member 91, the end of one of the lock block bodies 6 horizontally extends out of the first clamping portion 62, and the end of the other lock block body 6 corresponding to the first clamping portion 62 is outwardly and obliquely extended out of the second clamping portion 63, so that a locking space for the long member 91 in the longitudinal state to be inserted is formed between the first clamping portion 62 and the second clamping portion 63. When the rotating motor 9 is unlocked, the rotating motor 9 drives the long member 91 to rotate from the longitudinal state to the transverse state, so that the long member 91 props open the two locking piece bodies 6, the locking piece bodies 6 are released from propping against the locking hook 2, and unlocking is realized. During locking, the rotation motor 9 drives the long member 91 to rotate from the horizontal state to the vertical state, the two lock block bodies 6 are closed by the elastic force of the spring 22, and the long member 91 is clamped again by the first clamping portion 62 and the second clamping portion 63, so that locking is realized. It should be noted that the controller and the communication module may be arranged to be electrically connected to the rotation motor 9, so that the rotation motor 9 may be remotely controlled by using other terminals, thereby implementing remote unlocking and further improving convenience. The unlocking mechanism further comprises a power module 5 for supplying power to the rotating motor 9, the power module 5 is electrically connected with the rotating motor 9, and in order to facilitate production, the power module 5 and the bottom shell 11 are of an integrally formed structure in combination with fig. 1.

Compared with the prior art, the locking or unlocking of the lock hook 2 is realized by adopting the two rotatable and crossed lock block bodies 6, the original unlocking mode of horizontal movement of the lock block is replaced by the mode of rotating and unlocking the lock block bodies 6, the transmission relation among all parts is optimized, the whole transmission process is more compact and smooth, the wear of rotating and unlocking is less, the service life of the zipper coded lock is prolonged, the rotating and unlocking is more labor-saving than pushing and unlocking, and the unlocking is more convenient.
