Safety lock

Abstract

The invention disclose a safety lock. The safety lock comprises a lock with a lock cylinder or a lock without a lock cylinder, a groove formed in a pin which is in contact with a key is a groove withthe groove opening smaller than the groove bottom, a bottom edge with the upper bottom smaller than or equal to the lower bottom is arranged on a lock pin, in a locked state, the bottom edge is located in the bottom of the groove or outside the groove, and in an unlocked state, the bottom edge enters the bottom of the groove or the opening of the groove. According to the safety lock, handle unlocking or key unlocking is realized, multi-direction movement and large-distance movement of the pin can be realized to stop technical unlocking, and in the locked state, damage and technical unlocking can be further prevented through idling of the lock cylinder or a shifting wheel or a handle.

Problems solved by technology

[0003] Known fingerprint locks or face recognition locks have the following defects: electricity is required to limit the lock; the optical system for detecting fingerprints or face shapes is easy to wear and be damaged by attacks, and the fingerprints left on the lock are easy to be extracted by others and stolen Open the door; this related technology was demonstrated on the mobile phone at the 315 party in 2017, and the fingerprint or face of the non-owner was transformed into the required face shape or fingerprint and passed the recognition system smoothly; A tumbler lock must be equipped to open the door in an emergency. It is known that the safety of the tumbler lock is low, so that the security of the fingerprint lock is as poor as that of the tumbler lock. The advantage is that the method of unlocking and opening the door is simple and convenient

There are following several defects in the known tumbler lock: 1. unlocking and unlocking or opening the door all need a key, so that the key size is large, and when carrying more said keys, it brings inconvenience to people's lives; the key is easy to forget to take off after opening the door and The key hole left outside the door may be stolen by others; or ② the known lock has a cylinder lock, and the number of holes and pins is large, and it only needs to change the knife through the key hole to destroy the lock and open the door. The lock cylinder limits the number of marbles, which makes the lock's secret capacity low and the mutual opening rate high, resulting in low security of the lock; or ③ the parts of the pins that are in contact with the key cannot be unlocked in a hidden state or cannot be moved and changed. Made a cow; or ④ the setting method of the pin which is in contact with the key to unlock can only move in one direction and the moving distance is small, so that the technical unlocking can accurately determine the moving direction and moving distance of the pin from the key hole; or ⑤ known lock The structure cannot be unlocked by the wearable key or card key that is carried safely, and the problem that the key is easy to lose and easy to lock in the house cannot be solved; The V-shaped groove and the contact method between the lock pin and the internal pressure spring make the known lock exist: the mutual opening rate is high, and precise unlocking cannot be realized; or ⑦ The known lock structure cannot be opened or unlocked without a key Under locking or unlocking, the width of the groove on the pin is used to control and realize the multi-directional movement or large-distance movement of the pin, which cannot realize core lock or coreless lock. The lock core or dial can be less than or greater than 360 under the lock. or ⑧ known locks equipped with different unlocking authority keys, the lock core cannot rotate less than or greater than 360 degrees under the lock, and can only be set under the lock, and the lock core cannot rotate. Low lock; there is a problem of using a modified knife to destroy the lock through the keyhole, and there is a problem of technical unlocking
