Motion mechanism capable of controlling return of main lock tongue

Abstract

The invention discloses a motion mechanism capable of controlling return of a main lock tongue. The motion mechanism comprises a lower shell, a panel, the main lock tongue, an inclined lock tongue, an inclined tongue square hole, an inclined lock shifting fork, a sliding block, a motor, a gear, a gear pin and a gear pin fixing groove. In the invention, the motion mechanism which comprises the motor, the gear, the gear pin and the gear pin fixing groove and can prevent the main lock tongue and the inclined lock tongue from returning is not arranged inside an ordinary door lock; when the main lock tongue and the inclined lock tongue stretch out of the door lock for operation ( when the main lock tongue and the inclined lock tongue are in an opening state, the door lock and a door body are closed), a clamp ( a plug pin of the gear pin) of the motion mechanism can be moved to a connecting plate of the main lock tongue and is clamped in a bayonet lock groove in the connecting plate in an electronic or mechanical manner; the motion mechanism can be utilized as an obstacle to prevent the main lock tongue and the inclined lock tongue from returning to original positions in the opening state; and the safety protection function of preventing the door lock from being opened in abnormal ways such as malicious unlocking and lock picking is achieved.

Description

technical field [0001] The invention belongs to a novel lock body, and in particular relates to a movable mechanism capable of controlling the return of a main bolt. Background technique [0002] Existing common lock body is to control the opening and closing of main dead bolt and oblique dead bolt with key. When the main deadbolt and the inclined deadbolt are in the open state, the door lock and the door body are closed; when the main deadbolt and the oblique deadbolt are in the closed state, the door lock is separated from the door body, and the door body can be opened. Such a lock body can use a key to control the opening and closing of the main dead bolt and the oblique dead bolt, and can also use a tool to open or a technical opening to open the dead bolt without a key. In addition, if someone deliberately destroys the lock body to open the door lock, once the ordinary lock body is impacted by an external force, and the main bolt and oblique bolt of the lock body are d...

AI Technical Summary

Problems solved by technology

In addition, if someone deliberately destroys the lock body to open the door lock, once the ordinary lock body is impacted by an external force, and the main bolt and oblique bolt of the lock body are deformed, they will return to their positions (the main bolt and oblique lock The tongue is closed), the lock body is easy to pry open, and the door body is broken open

Therefore, ordinary door locks also have great potential safety hazards when there are no specific protective measures.
