AI Technical Summary

Technical Problem

In the intelligent gate control system, the lock tongue and the door body are prone to friction and squeeze, resulting in the opening of the door leaf requiring sufficient force and poor flexibility, which cannot meet the use needs of intelligent gate control.

Method used

A tongue lock mechanism is designed, including a tongue lock assembly, an operating assembly and an unlock assembly. The locking tongue assembly has a locking tongue part and a latch part. Through the cooperation of the locking elastic member and the locking slide, external force is used to drive the coupling member to slide, compress the locking elastic member, so that the locking slide is away from the locking tongue part, thereby unlocking the limiting part and the docking part, realizing the flexible rotation of the locking tongue part.

Benefits of technology

Through the design of the locking tongue mechanism, the friction and squeezing force between the locking tongue part and the door body is reduced, and the more labor-saving and flexible unlocking displacement of the locking tongue part is achieved, meeting the needs of the intelligent gate control system.

Abstract

The invention discloses a spring bolt mechanism, a lock and an intelligent door control system, and relates to the field of lock assembly. The spring bolt mechanism comprises a spring bolt assembly, an operation assembly and an unlocking assembly. According to the spring bolt mechanism provided by the invention, the unlocking assembly is linked through the sliding movement of the connecting piece, so that the locking sliding block slides away from the spring bolt part, the limiting part of the locking sliding block and the butt joint part of the spring bolt part are unlocked, and the spring bolt part can flexibly rotate relative to the bolt part; the purposes of auxiliary unlocking and flexible unlocking are achieved; and if the spring bolt assembly and the external door body need to return to the locking state, the sliding acting force of the connecting piece can be removed, the locking sliding block slides towards the spring bolt part under the elastic action of the locking elastic piece, and the limiting part and the butt joint part can be reset and locked. According to the scheme, connection and unlocking between the spring bolt part and the external door body can be effectively assisted, and the operation process is more labor-saving and more convenient for a user and intelligent door control.
