Self-popping lock body

Abstract

The invention discloses a self-popping lock body. In the door closing process, a scissor tongue and a detecting tongue are pressed at the same time. When the scissor tongue enters a door frame and is popped, a self-locking trigger block moves upwards under the effect of a self-locking resetting spring and drives a self-locking connecting rod to move together. After the self-locking connecting rod breaks away from limiting cooperation with a main locking tongue, the main locking tongue automatically stretches out under the effect of a main locking tongue torsional spring, and door closing action is completed. The self-popping lock body has the advantages that 1, after a door is closed, the main locking tongue is popped automatically, and use is easy and convenient; 2, the scissor tongue and the detecting tongue are popped at the same time, the main locking tongue is not popped, and the situation of unlocking and error popping is avoided; 3, popping is more effective, the product stability is improved, and using time is longer. Furthermore, under the effect of restoring force of a connecting rod restoring mechanism, a limiting structure at the tail end of the self-locking connecting rod can be kept in a main locking tongue groove, stretching out of the main locking tongue is stopped, the main locking tongue is locked, and the stability is improved.

Description

technical field [0001] The invention relates to the technical field of lock bodies, in particular to a self-elastic lock body. Background technique [0002] As a smart home product, smart door lock has entered the fast lane of development. Its convenience, safety and sense of technology have gradually been recognized and favored by consumers. [0003] At present, the smart door locks on the market are basically double-fast locks. After closing the door, you need to lift the handle to lock the door, which has a poor experience. People strongly demand a product that locks automatically after closing the door, which is simpler and more convenient to use. [0004] The stability of the self-elastic lock body in the prior art still needs to be improved: [0005] 1) There is a high probability of false cover and miss-fire, that is, the detection tongue and the scissor tongue will pop out at the same time after being pressed at the same time, and the main lock tongue will be relea...

AI Technical Summary

Problems solved by technology

[0005] 1) The probability of false cover is high, that is, the detection tongue and the scissors tongue will pop out at the same time after being pressed at the same time, and the main lock tongue will be released;

[0006] 2) The stability is poor, and it often fails to lock;

[0007] 3) Difficult assembly and poor stability;

[0008] 4) The ejection force of the main lock tongue is small, and it often happens that it cannot be ejected
