Description

A kind of anti-collision door lock

The utility model relates to a kind of door lock, particularly a kind of anti-collision door lock.

General anti-collision door lock is the mode that adopts reinforcing dead bolt and tongue to buckle at present; but because more doorframe is wooden at present; and the stressed tongue that is added to fully of dead bolt is buckled when colliding door lock; if doorframe is relatively poor; when colliding door lock tongue buckle with doorframe destroyed, and doorframe tongue is buckled when harder that itself or the easy glass of attachment screw are bad.

The purpose of this utility model provides a kind of door lock of washing the tongue button open that can effectively prevent to collide outdoors.

The technical solution of the utility model is a kind of anti-collision door lock of design, comprises lock body, and the dead bolt end face of lock body is an inclined-plane, it is characterized in that: an inclined-plane that cooperates with the dead bolt inclined-plane is arranged in the tongue button.

The utility model has the advantages that to prevent from effectively to collide outdoors and wash the tongue button open.

Below in conjunction with accompanying drawing the utility model is elaborated,

Accompanying drawing is the partial cutaway schematic of the utility model figure, comprises lock body 1 among the figure, and dead bolt 2 end faces of lock body 1 are an inclined-plane 3, it is characterized in that: an inclined-plane 5 that cooperates with dead bolt inclined-plane 3 is arranged in the tongue button 4.During use when lock pins, because dead bolt 2 end faces are an inclined-plane 3, and the inclined-plane 5 in the inclined-plane 3 corresponding tongue buttons 4, when external force is collided door, dead bolt 2 is subjected to a vertical power, and the vertical power that the inclined-plane 3 of dead bolt 2 is subjected to dead bolt 2 resolves into a horizontal force and Chui Li and passes to inclined-plane 5 in the tongue button 4, the power that tongue button 4 is passed to power in inclined-plane 5 in the tongue button 4 is the power and a vertical power of a horizontal direction, because power is decomposed, the vertical power that tongue button 4 is subjected to will reduce, because doorframe is outward a cement wall, the horizontal force that tongue button 4 is subjected to does not play destruction to tongue button 4, therefore tongue button 4 is not fragile, yet not fragile doorframe.
