Description

Technical Field

[0001] This utility model relates to the field of lock assembly technology, and in particular to an automatic lock tongue assembly device. Background Technology

[0002] A lock is a device used to close or secure objects. It uses mechanical structures, electronic controls, or biometrics to lock and unlock target objects, ensuring the safety of items and the privacy of spaces. Its core principle is the use of a lock cylinder, bolt, and key to form a controllable closing mechanism. The bolt is a key component of the lock structure, typically a strip-shaped or columnar metal member installed on the edge of the door. It engages with a keyhole or strike plate on the door frame to achieve the locking and unlocking functions of the door. The latch structure usually includes multiple precision parts such as springs, tongues, and guides. Manual assembly of each step requires separate operations, and each process is time-consuming. It is difficult to increase production capacity when mass production is carried out. The three-pronged latch requires the simultaneous assembly of the upper, middle, and lower latch components. Manual alignment has low accuracy and is prone to interference between multiple components. Therefore, it is necessary to propose an automatic latch assembly device. Utility Model Content
