Lock body structure

Abstract

The invention discloses a lock body structure. The lock body structure comprises a lock body shell, a lining plate provided with a spring bolt hole, a limiting groove component arranged at the side, close to the spring bolt hole, in the lock body shell and provided with a side hole in one side wall, an overturning tongue, a positioning spring, a locking assembly, an unlocking assembly and a handle; the overturning tongue is arranged in the open end of the limiting groove component and can move in the length direction of the limiting groove component, a limiting protruding block is arranged on the side portion of the overturning tongue, a clamping groove is formed in the rear end of the overturning tongue, a limiting clamping plate with the length larger than the width of the overturning tongue is arranged on the side wall of one side of the clamping groove, and the front end of the overturning tongue penetrates through the spring bolt hole; the positioning spring is arranged in the limiting groove component, one end of the positioning spring is connected to the bottom surface of the limiting groove component, and the other end of the positioning spring applies elastic force to the bottom surface of the clamping groove; the locking assembly is rotationally installed on a pin shaft arranged on the lock body shell, and one end of the locking assembly can penetrate through the side hole to extend into the limiting groove component and abut against the limiting clamping plate; the unlocking assembly is used for controlling the locking assembly to rotate; and the handle is used for controlling the unlocking assembly to rotate. The lock body structure has the advantage of being short in unlocking stroke, and unlocking is more convenient.

Description

technical field [0001] The present invention relates to the technical field of locks, in particular to a lock body structure. Background technique [0002] At present, most of the bolt types of locks are the oblique bolt type that can only be extended and retracted. The general oblique bolt type deadbolt can quickly rebound under the action of the elastic force to automatically lock the door when closing the door, but the oblique bolt type deadbolt The stroke when unblanking is relatively long, and the opening force is also relatively large. When the oblique tongue lock is installed in a humid place such as a bathroom, it is easy to get wet on the hands, and it is easy to slide between the hand and the lock handle when unlocking, and it is difficult to open the lock. At this time, the oblique tongue lock has a long unlocking stroke and a strong opening force. The shortcomings are more prominent. In addition, since the bathroom lock is usually not equipped with a key, when ...

Problems solved by technology

When the oblique tongue lock is installed in a humid place such as a bathroom, it is easy to get wet on the hands, and it is easy to slide between the hand and the lock handle when unlocking, and it is difficult to open the lock. At this time, the oblique tongue lock has a long unlocking stroke and a strong opening force. The shortcomings are more prominent

In addition, since the bathroom lock is usually not equipped with a key, when the anti-lock device is activated by misoperation, closing the door outside the door will cause the door to be anti-locked

At this time, one gives the false impression that someone is in the bathroom, and the other requires professional tools to open the door
