An in-line door lock with anti-reverse function of lock cylinder

Abstract

The invention discloses a straight insert type door lock capable of preventing reverse rotation of a lock core. The straight insert type door lock capable of preventing the reverse rotation of the lock core comprises a motor substrate, a speed change gear box, a pitched top gear, a rack and a lock core mechanism, the speed change gear box is fixed on the motor substrate, the pitched top gear is arranged at the side wall of the speed change gear box, one end of the rack is engaged to the pitched top gear, and the other end is connected with the lock core mechanism; the pitched top gear is provided with a pitched force arm, and a pitched rack baffle block is fixed at the side of the rack; the pitched rack baffle block is concave and comprises a front baffle block and a rear baffle block; the lock core mechanism is provided with a plurality of lock cores. According to the technical scheme, the pitched force arm is arranged on the pitched top gear, and meanwhile, the pitched rack baffle block is arranged at the side of the rack, when the lock core rotates reversely, the movement of the pitched force arm of the gear is stopped through the pitched rack baffle block, and accordingly the reverse rotation of the gear and rack is limited, the reverse rotation of the lock core is avoided, and the safety performance of a glass door lock is improved.

Description

technical field [0001] The invention relates to the field of locks, in particular to an in-line door lock with the anti-rotation function of a lock cylinder. Background technique [0002] With the progress of society and the development of science and technology, intelligent life has begun to become popular. In the intelligent family, intelligent door lock is one of the more important roles. Because it has higher anti-theft performance than mechanical door locks, So by the majority of users of all ages. [0003] At present, smart locks can be divided into card electronic locks, fingerprint identification electronic locks and password electronic locks according to their performance. According to the occasion, it can be divided into: hotel electronic locks, fingerprint door locks, fingerprint room door locks, cabinet door electronic locks, glass door electronic locks, etc. [0004] At the same time, the above-mentioned door locks generally use American standard five-tongue l...

AI Technical Summary

Problems solved by technology

However, neither the American standard five-tongue lock cylinder nor the in-line lock cylinder has the function of anti-reversal; that is, the in-line lock cylinder in the door lock forms a transmission structure through the rack and the upper gear of the motor. Pushing the rack and then reversing when the rack drives the gear, it is easy to cause unsafe hazards

For example, when the two doors are pulled at the same time, a gap will be formed, so that the lock cylinder can be retracted into the lock body by some external force device, and then the door can be opened directly, which cannot play a good protective effect.
