Self-lock device of sliding door

Abstract

The invention discloses a self-lock device of a sliding door. The device comprises a lock body (1), a lock case (2), a controller (10), a bolt (5) and a lock jaw (4); the lock body is fixedly arranged inside the lock case (2), the lower portion of the lock case (2) is provided with a sleeve (8), a connecting rod (9) is slidingly arranged inside the sleeve (8), the lock jaw (4) is fixedly arranged on the bottom end of the connecting rod (9), the top end of the connecting rod (9) is fixedly provided with a magnetic core (6); the bolt (5) is arranged on a sliding door (12) through a bolt installing seat (11). The sliding door can be locked when closed and can effectively avoid the potential security problems that non-professional workers fall on tracks or litter on the racks to affect train driving when standing casually on platform and opening the sliding door. The self-lock device of the sliding door has the advantages of being simple in structure, low in manufacturing cost, reasonable and stable in structural design, good in locking effect, long in service life, convenient to mount, maintain and dismount, rapid in corresponding speed, low in energy consumption during self-locking process and low in operating cost.

Description

technical field [0001] The invention relates to a sliding door self-locking device. Background technique [0002] With the rapid development of social economy and urban construction level, rail transit is becoming more and more important in urban public transportation system. The screen door system used in rail transit is a typical electromechanical integration product. It is arranged along the edge of the rail transit platform to isolate the station platform from the locomotive tunnel. It can not only prevent people and objects from falling on the track, but also reduce air conditioning in the station. The operating energy consumption of the ventilation system can reduce the impact of train operation noise on the station. [0003] However, most of the existing rail transit screen door systems are not designed with a locking device when the sliding door is closed, and non-professional staff such as passengers or cleaners can open the sliding door at the platform side at wil...

AI Technical Summary

Problems solved by technology

[0003] However, most of the existing rail transit screen door systems are not designed with a locking device when the sliding door is closed, and non-professional staff such as passengers or cleaners can open the sliding door at the platform side at will, which brings great safety. Hidden danger

[0004] In addition, the sliding door closing and locking devices currently on the market mainly use the mechanical transmission mechanism for auxiliary control of the opening and closing process. Due to the influence of the structure, false locks are prone to occur. At the same time, due to the limitation of the mechanical transmission process, when opening There will also be response lag and untimely phenomena, which will bring safety hazards to the use of sliding doors, and will also threaten the personal and property safety of passengers.
