Description

The Door-lock bolt assembly

The utility model relates to a kind of dead bolt assembly of door lock.

Existing Door-lock bolt branch has oblique tongue and square tongue, and the one side of existing oblique tongue is that inclined-plane, one side are the planes, and tiltedly the rear end of tongue is provided with the compression spring.At closing time, the tiltedly inclined-plane of tongue and snap close collision, lock body is applied certain pressure, snap close pushes oblique tongue is retracted in the lock body it, the housing that streaks snap close when the oblique tongue tongue that retreads can enter in the snap close under the effect at spring, at this moment, tiltedly the tongue plane right direction be the direction of a unlatching, have only with key or handle oblique tongue indentation lock body inside door could be opened once more.The oblique tongue assembly main characteristics of this door lock be can only folk prescription to closing the door, will there be another direction that the oblique tongue on inclined-plane has been set for the situation of closing the door from another direction, for seeming powerless from the existing oblique tongue total performance of locking of the situation that both direction is closed the door because of actual needs.

The purpose of this utility model is to overcome the above-mentioned defective of prior art, provide a kind of can be from the both direction the oblique tongue assembly of operable door lock simultaneously.

The utility model comprises oblique tongue, oblique tongue connecting rod, oblique tongue spring, tiltedly tongue is positioned at an end of oblique tongue connecting rod, tiltedly the tongue spring is positioned at the rear end of oblique tongue, its technical solution is that the front end of oblique tongue is a triangle, rear end at oblique tongue is provided with groove, tiltedly the tongue connecting rod is arranged in groove and is hinged on the middle part of oblique tongue with oblique tongue, simultaneously at oblique tongue with tiltedly be provided with positioner between the tongue connecting rod.

In the utility model tiltedly arbitrary face of tongue be under pressure, tiltedly tongue all can be around the pin joint rotating certain angle, contact with obstacle on being arranged on lock body until oblique tongue, the face that is stressed of at this moment oblique tongue is along with the swing of oblique tongue is the inclined-plane.So just can realize that oblique tongue can use simultaneously on both direction.
