Specifically, in the present design, by setting the password locking component 5, when it is necessary to unlock the door, the password roller 14 on the password locking component 5 is rolled so that the password locking component 5 no longer presses the push rod locking piece 7. At this time, the push rod locking piece 7 is separated from the lock core push rod 6, and the lock core push rod 6 can move in the lock core transmission cavity 4, so that the lock core push rod 6 moves toward the lock core 3 to lift the lock core 3 and perform an upward action, so that the lock core 3 leaves the lock hole 27 on the mounting seat 1 to achieve the purpose of unlocking the door. When it is necessary to lock the door, the password roller 14 is continued to be rotated so that the password locking component 5 presses the push rod locking piece 7 again, and the push rod locking piece 7 is again limited with the lock core push rod 6 to limit the movement of the lock core push rod 6, thereby keeping the lock core 3 in the lock hole 27 to achieve the effect of locking. The present design does not require a key to unlock the door, and the key will not be lost. The unlocking and locking operations are convenient.

[0022] Furthermore, a locking groove 8 is provided on the lock core push rod 6, and the push rod locking piece 7 has a body part 9 and a locking part 10. The body part 9 is mounted on the password locking assembly 5, and the locking part 10 is formed protruding on one side of the body part 9. The locking part 10 is formed by bending one side of the body part 9 toward the locking groove 8. A locking piece transmission part 11 is formed protruding on the body part 9. The password locking assembly 5 is rotated to press the locking piece transmission part 11. The locking part 10 extends into the locking groove 8 and cooperates with the lock core push rod 6 to limit the movement of the lock core push rod 6 in the lock core transmission chamber 4. Specifically, in this embodiment, by designing the structure of the locking groove 8 and the push rod locking piece 7, the movement of the lock core push rod 6 is precisely controlled. When the password lock assembly 5 presses the push rod locking piece 7, the locking portion 10 of the push rod locking piece 7 extends into the locking groove 8, forming a limit fit with the lock core push rod 6, thereby limiting the movement of the lock core push rod 6 in the lock core transmission chamber 4. When unlocking is required, the password lock assembly 5 no longer presses the push rod locking piece 7 by rolling the password roller 14. At this time, the locking portion 10 of the push rod locking piece 7 is separated from the locking groove 8, and the lock core push rod 6 is able to move in the lock core transmission chamber 4, thereby pushing the lock core 3 up to achieve the purpose of unlocking.

[0023] Furthermore, the password lock assembly 5 includes a positioning seat 12, a positioning shaft 13, a password roller 14 and a lock plate pressing member 15. The positioning seat 12 is fixedly connected to the inner wall of the lock core transmission chamber 4 by screws (not shown in the figure). A shaft mounting portion 16 is provided on one side of the top of the positioning seat 12.

The lock plate pressing member 15 is connected to the lock plate transmission portion 11. Specifically, in this embodiment, the positioning seat 12 serves as a fixed base of the password lock assembly 5. It is fixedly connected to the inner wall of the lock core transmission chamber 4 by screws, which ensures the stability and reliability of the assembly. The positioning seat 12 will not be driven to move during the movement of the lock core push rod 6. The setting of the positioning shaft 13 not only provides a rotation center for the lock plate pressing member 15 and the password roller 14, but also ensures the stability of the relative position between them. The lock plate pressing member 15 is sleeved on the positioning shaft 13 and connected to the lock plate transmission part 11 of the push rod locking plate 7. When the password roller 14 is rotated, the lock plate pressing member 15 will rotate accordingly, thereby realizing the pressing and releasing operation of the push rod locking plate 7. The password roller 14 is used as an interface for user operation. It is sleeved on the lock plate pressing member 15. The user can input the unlocking password by rolling the password roller 14. The operation is simple and intuitive. When the user rolls the password roller 14, only when the correct password combination is entered can the lock plate pressing member 15 release the push rod locking plate 7, thereby allowing the lock core push rod 6 to move in the lock core transmission chamber 4. This design can effectively prevent illegal unlocking and improve the safety of the motorcycle lock.
