Mechanism capable of controlling lock core shifting movable piece to perform reciprocating motion

Abstract

The invention discloses a mechanism capable of controlling a lock core shifting movable piece to perform reciprocating motion. The mechanism comprises a lower shell, a main lock tongue device, a heaven and earth hood assembly, an electromagnet, a swinging part, a twisting column and a plug pin pile body. In the invention, the mechanism which comprises the heaven and earth hood assembly, the electromagnet, the swinging part, the twisting column and the plug pin pile body and can control the lock core shifting movable piece to perform reciprocating motion is not arranged inside an ordinary door lock; when a main lock tongue stretches out of the door lock for operation (when the main lock tongue is in an opening state, the door lock and a door body are closed), the lock core shifting movable piece of the motion mechanism can be moved to the return position of the main lock tongue in an electronic or mechanical manner; the motion mechanism can be utilized as an obstacle to prevent the main lock tongue from returning to an original position 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. According to the mechanism, the structure is simple while an application measure is unique, and the effect is remarkable.

Description

technical field [0001] The invention belongs to a new type of lock body, and in particular relates to a mechanism capable of controlling the reciprocating movement of a shifting movable piece of a lock cylinder. 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 mai...

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.
