Description

Technical Field

[0001] The present application relates to the field of locks, and in particular to a cable lock head. Background Art

[0002] The cable lock usually comprises a lock head, a lock buckle 4 and a steel cable connecting the lock head and the lock buckle 4. When the lock buckle 4 is locked on the lock head to form a closed loop, the cable lock is in a locked state.

[0003] Reference Figure 1 , Figure 2 The steel cable lock in the related art includes a lock head, a lock buckle 4 and a steel cable connecting the lock head and the lock buckle 4. The lock head includes a lock shell 1, an unlocking lever 3 hingedly arranged in the lock shell 1, and a lock core 2 slidably arranged in the lock shell 1. A slot 121 for inserting the lock buckle 4 is opened on the lock shell 1. One end of the lock core 2 is located in the slot 121. The sliding direction of the lock core 2 is along the length direction of the lock core 2. When in the locked state, the lock buckle 4 is inserted into the slot 121, and the end of the lock core 2 located in the slot 121 is located in the lock buckle 4.

[0004] Reference Figure 2 A driving groove 22 for accommodating the end of the unlocking lever 3 is provided on the side wall of the lock core 2. A driving mechanism 5 for driving the unlocking lever 3 to lift up away from the end of the driving groove 22 is also provided in the lock housing 1. When the unlocking lever 3 is lifted up away from the end of the driving groove 22, the unlocking lever 3 is located at the end of the driving groove 22 and presses down the lock core 2, making it convenient for the lock buckle 4 to disengage from the driving groove 22, thereby achieving unlocking. A return spring 21 is provided in the lock housing 1, and the return spring 21 drives the end of the lock core 2 to keep abutting against the groove wall of the driving groove 22.
