Steel rope-connecting automatic lock

Abstract

The invention relates to a steel rope-connecting automatic lock, which comprises a main lock, a pusher and a driving steel rope. A main lock bolt, a shifting device of the main lock bolt, a limiting device of the main lock bolt, and an engaging and disengaging device of the main lock bolt are arranged in the main lock body. The pusher comprises a pusher seat, a push rod mechanism, a slide block mechanism and a shift block mechanism, wherein the push rod mechanism, the slide block mechanism and the shift block mechanism are slidingly arranged in the pusher seat. The driving steel rope comprises a first driving steel rope and a second driving steel rope. One end of the first driving steel rope is connected with the slide block mechanism, and the other end thereof is connected with the shifting device of the main lock bolt. One end of the second driving steel rope is connected with the engaging and disengaging device of the main lock bolt, and the other end thereof is connected with the shifting block mechanism. A latch bolt which is exposed out of the pusher seat is arranged in the push rod mechanism. When a door is locked, the latch bolt is retracted into the pusher seat after contacting with a door frame, and pushes the slide block mechanism to move forwards. The invention aims to provide the steel rope-connecting automatic lock which has the advantages that all locking pointsare automatically locked when the door is closed; the door can be opened without rotating the outdoor key after the outdoor key is inserted into a lock cylinder; and all the locking points can be opened by an indoor handle.

Description

Technical field: [0001] The invention relates to a lock set for a door, in particular to an automatic lock connected by a steel rope. Background technique: [0002] The door locks used in the past need to be realized by turning the key to lock and unlock the door, which is not only inconvenient to use, but also has poor anti-theft performance. For this reason, some improved structures have also appeared in the world at present. [0003] For example, Chinese utility model patent ZL200520049894.X discloses a kind of anti-theft lock that can use the collision force of closing the door to make the lock bolt stretch out and rotate 90 degrees to lock the door. It consists of a spring trigger mechanism, a lock bolt linkage mechanism, an oblique bolt and It is composed of connecting rod assembly, lock bolt self-locking control mechanism, lock case assembly and "king"-shaped rotary bolt with straight push ring groove and rotating straight teeth at the tail, stop pin at the middle, a...

AI Technical Summary

Problems solved by technology

[0004] 1. When closing the door, it is necessary to take out the lock bolt and then rotate it 90 degrees to lock the door. On the one hand, it brings inconvenience to the operation, and on the other hand, many parts are added, making the structure very complicated and the manufacturing cost increase; at the same time, because there are too many intermediate transmission links, it is easy to have dislocation or loose fit during use, which will lead to lock failure

[0005] 2. Due to the increase of components and they are all installed in the same lock body, the volume of the lock body is larger than that of ordinary locks. However, some existing high-end anti-theft doors usually have multiple pairs of locks installed on the door. If multiple pairs of the patent Described lockset is installed on the high-grade anti-theft door, obviously not economical and practical enough

[0006] 3. The door opening of the lock through the smart card is actually realized by the motor controlling the mechanism inside the lock body, so it can only be used when the power supply is guaranteed. Once the power is cut off, the user cannot open the anti-theft door, which affects the reliability of use. , causing inconvenience to users
