Abstract

The utility model relates to a door lock with a mistaken collision preventing device, which comprises a lock body part and a roller component, wherein a fixed pin 12 and a fixed pin 16 of the lock body part are fixedly connected with a lock body 18, and a movable pin 14 is fixedly connected with a main square latch 1. A clamping block 9 is positioned at the right end of a touch latch 2, and a clamping groove 19 matched with the clamping block 9 is arranged on a translational block 11. The roller component is composed of a small roller 3, a small shaft 7, a slide block 6, a pressure spring 5 and a shell body 4, wherein the small roller 4 is arranged on the small shaft 7, and the small shaft 7 is arranged on the slide block 6. The slide block 6 is arranged in the shell body 4, and the pressure spring 5 arranged in the shell body 4 is positioned on the top part of the slide block 6. The roller component is arranged in a doorframe fastening board 8. The end parts of the touch latch 2 are on the same level with a panel of the lock body under the state that the door lock is opened, and a broken end of the touch latch 2 is a plane surface. The utility model has the advantages of avoiding the problem that a door can not be closed due to the ejected main square latch as a result of a traditional door lock which is easy to collide by external force since the touch latch is bulged out of the panel of the lock body.

Description

Door lock with mistaken collision preventing device

Technical field

The utility model relates to lockset, especially a kind of door lock with mistaken collision preventing device.

Background technology

Traditional have a door lock that bumps tongue, and it bumps tongue and protrudes in the lock panel outside, and head is the inclined-plane, when at closing time, bump the inclined-plane of tongue portion and the buckle on the doorframe and collide, under the effect of doorframe buckle, bump tonguing and go into lock panel and make to bump the tongue translation piece of the fixture block disengaging lock body of end in addition.The translation piece moves down along steady pin by chute under the effect of extension spring, and moves to left by the removable pin promotion master side tongue with master side's ankyloglossia, enters in doorframe buckle and the doorframe, door lock is lived (referring to the lock body part of Fig. 1, Fig. 2).The problem that this structure exists is owing to bump the tongue protrusion in the lock panel outside, is easy to be subjected to touching of external force, causes master side's tongue to eject, and can't further door be closed.

Summary of the invention

The purpose of this utility model is to bump the door lock of tongue at traditional having, it bumps tongue and protrudes in the lock panel outside, be easy to be subjected to touching of external force, cause master side's tongue to eject, the problem that can't further door be closed, provide a kind of and can prevent to bump tongue and be not intended to be subjected to touching of external force, cause master side's tongue to eject the door lock that influence is further closed door with mistaken collision preventing device.

Door lock with mistaken collision preventing device described in the utility model comprises lock body, lock panel, master side's tongue, torsion spring, bumps tongue, translation piece, fixture block, stage clip, draw-in groove, two steady pins, removable pin, extension spring and doorframe buckle.Two steady pins and lock body are connected, removable pin and master side's ankyloglossia.Fixture block is positioned at the right-hand member that bumps tongue, and the draw-in groove that cooperates with fixture block is located on the translation piece.In addition, the door lock with mistaken collision preventing device also is provided with a roll wheel assembly.Roll wheel assembly is made of trundle, little axle, slide block, stage clip and housing.Roller is contained on the little axle.Little axle is contained on the slide block.Slide block is loaded in the housing.Stage clip is loaded in the housing, is positioned at the top of slide block.Roll wheel assembly is loaded in the doorframe buckle.Bump tongue its end under the door lock opening and flush, and the broken end that bumps tongue is the plane with lock panel.

The utility model has the advantages that when at closing time, the roller of roll wheel assembly is under the effect of stage clip, slide block, little axle, promotion is bumped tongue and is moved to right, and makes the draw-in groove on the fixture block disengaging translation piece that bumps the tongue right-hand member, and the translation piece moves down, promote master side's tongue by removable pin and move to left, door lock is closed with master side's ankyloglossia.Avoided conventional door lock to be easy to be subjected to touching of external force in the lock panel outside, caused master side's tongue to eject the problem that further door to be closed owing to bumping the tongue protrusion.
