Motor unidirectional control, self-spring lock with detached teeth

Abstract

The invention discloses a self-pop-up lock with a motor unidirectionally controlling tooth disengaging. The motor of the self-pop-up lock is fixed at an adaptive position of a partition frame at the middle part in a shell; a spiral gear on one side in the shell is connected with a motor shaft; the spiral gear meshes step by step with a driving gear and a three-layer gear on a stand column fixed on the front wall of the shell; at least one compressed spring is arranged in a spring shell of a columnar pipeline fixed at the middle part of the upper wall of the shell; an insert hole which fits with the door frame in shape is arranged at a position, corresponding to the spring shell, on the front wall of the shell; an L-shaped spring bolt is fixedly arranged on a support turning bar at an adaptive position at the lower end of the columnar pipeline; rattrap springs respectively arranged on both sides of the spring bolt are also fixed on the support turning bar; a lever and a torsional spring which successively sleeve the stand column on the front wall of the shell are arranged at adaptive positions at the lower end of the spring bolt; a groove is formed at the middle part of the lever; a finger-bending hook and an arc stop are respectively arranged at two ends of the groove; one end of the torsional spring is hooked on the lever, and the other end is stuck on a support on the inner wall of the shell. The self-pop-up lock provided by the invention is stable in performance, and realizes no wait for door opening and closing.

Description

technical field [0001] The invention relates to a lock, in particular to a motor single-direction control tooth-off self-spring lock. Background technique [0002] At present, the single-spring deadbolt electronic locks currently used in bathing venues need to wait for the deadbolt to be retracted before manually opening the cabinet door after swiping the card. It is necessary to wait for the motor to reverse to make the deadbolt return to the original position before locking the door. After the door cannot be opened Lock the door immediately. Poor anti-picking performance, the lock can be unlocked by pushing the lock tongue in the opposite direction, and the noise is loud. Long-term use of worn gears requires high installation accuracy, and it is easy to have the lock tongue not fully extended in place, and it is difficult to detect when the lock is false. [0003] After swiping the card of the existing Tiandi pole electronic lock, it is necessary to wait for the lock tong...

AI Technical Summary

Problems solved by technology

Because there is no tooth removal structure, an additional electronic sensor is required to monitor the state of the lock tongue, and the anti-picking performance is poor, and the lock can be unlocked by pushing the lock tongue in the opposite direction

[0004] The existing pop-up locks also have the above-mentioned shortcomings, and have high requirements on the consistency and stability of the motor, which may cause cumulative errors to cause the deadbolt to be stuck and the door cannot be locked.

The gear-off structure leads to high noise, fast gear wear, and short life. The motor needs to be controlled in forward and reverse directions, resulting in high power consumption and double wear

Therefore, it brings great trouble to users
