Abstract

The utility model belongs to a door lock, comprising a lock catch, a lock body and a lock tongue, wherein the lock tongue is the flat lock tongue; the front surface and side surfaces of the lock catch are provided with lock tongue holes corresponding to the transverse insertion and the left and right telescoping of the flat lock tongue; the lock catch is provided inside with a reverse locking mechanism corresponding to the transverse insertion of the flat lock tongue; the flat lock tongue can be drawn back in the lock body; when the flat lock tongue is stretched out the lock body, the door lock can be conveniently locked; moreover, the flat lock tongue can not be moved from the outside by a hard flake; therefore, the utility model has the advantages of convenient use and high security, etc.

Description

Door lock

Technical field

The utility model belongs to a kind of door lock.

Background technology

In the prior art, door lock generally includes snap close, lock body, and is contained in the inclined-plane dead bolt in the lock body.The door lock of monolock tongue structure, there is the jack of inclined surface dead bolt telescopic moving its snap close side, after the inclined-plane dead bolt puts in this jack, door leaf is just locked, and behind the inclined-plane dead bolt withdrawal lock body, door leaf just can be opened, it is simple in structure, easy to use, but this kind door lock poor safety performance, its inclined-plane dead bolt is easily utilized hard thin slice to push aside and door leaf is opened by the stranger.For this reason, people's door is on the basis of monolock tongue structure door lock, the method of setting up one or several bumper bars is in addition arranged to strengthen its safety again, but this class door lock all must just can make bumper bar stretch out or the lock body of withdrawing by using key, thereby exist inconvenient problem with use, as closing behind the door, the people just can lock door leaf after just must making dangerous bar stretch out lock body with key outdoors; After opening the door, the people just can shut door leaf indoor after also must making earlier bumper bar withdrawal lock body with key, otherwise door leaf does not just close.Therefore, use it pretty troublesome again.

Summary of the invention

For solving the problem that there is poor stability in above-mentioned door lock and uses trouble, the utility model proposes the strong door lock of a kind of property easy to use, safe.

Described the utility model door lock, comprise snap close 1 and lock body 2, dead bolt 3 is housed in the lock body 2, the dead bolt jack that the side of snap close 1 has corresponding dead bolt 3 to stretch, particularly described dead bolt 3 is the plane dead bolt, there is the horizontal opening of going into of the corresponding flat dead bolt that is communicated with the dead bolt jack in the snap close front, and the horizontal counteresteer mechanism of going into of corresponding flat dead bolt is housed in the snap close.

Described plane dead bolt cross section can be triangular facet; Described counteresteer mechanism can collude 5 by the activity of a pair of oblique top face, pivot pin 4 and spring 6 are formed, 5 bottom is colluded in activity has pin hole and corresponding spring that the breach of usefulness is installed, activity collude 5 and spring 6 all be enclosed within on the pivot pin 4, two terminations of pivot pin 4 are installed in snap close, and the lumen pore that 5 bottom structure has a corresponding flat dead bolt to fall into is colluded in two activities; Drift angle is colluded in described activity can be the 20--45 degree.

The utility model is owing to adopt the plane dead bolt, and also have a horizontal opening of going into of corresponding flat dead bolt in the snap close front, the horizontal counteresteer mechanism of going into of corresponding flat dead bolt is housed in the snap close, can be horizontal go in the snap close by locking thereby make the plane dead bolt stretch out behind the lock body, when the plane dead bolt stretches out lock body also easily on the spring lock, and, not open plane dead bolt dialled with hard thin slice outdoors, when opening the door, can open door after need only making plane dead bolt withdrawal lock body.Therefore, the utlity model has advantages such as property easy to use, safe is strong.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is a counteresteer mechanism element schematic diagram among Fig. 1.

Structural representation when Fig. 3 goes into snap close by locking for dead bolt among Fig. 1 is horizontal.

The utility model comprises snap close 1, lock body 2, dead bolt 3, wherein counteresteer mechanism by the activity of a pair of oblique top face collude 5, pivot pin 4 and spring 6 form, the lumen pore that 5 bottoms have a corresponding flat dead bolt to fall into is colluded in two activities, there is the flexible dead bolt jack of corresponding flat dead bolt the side of snap close 1, there is the horizontal opening of going into of the corresponding flat dead bolt that is communicated with the dead bolt jack in the front of snap close 1, and the horizontal counteresteer mechanism of going into of corresponding flat dead bolt is housed in the snap close.

The specific embodiment

A kind of door lock comprises snap close 1, lock body 2, dead bolt 3, and by the activity of a pair of oblique top face colludes 5, pivot pin 4 and spring 6 are formed counteresteer mechanism.Described dead bolt 3 is the plane dead bolt, its cross section is a triangular facet, it is 20 degree that 5 oblique top angles are colluded in activity, 5 bottom is colluded in activity pin hole, 5 the middle breach that has corresponding spring that usefulness is installed in bottom is colluded in activity, activity collude 5 and spring 6 all be enclosed within on the pivot pin 4, two terminations of pivot pin 4 are installed in the pin-and-hole at snap close 1 rear portion, the lumen pore that 5 bottom structure has a corresponding flat dead bolt to fall into is colluded in two activities.

Go into the front openings of snap close 1 when dead bolt 3 is horizontal, and after two activities that act on collude 5 oblique top faces, two activities are colluded top and outwards are pushed separately, the plane dead bolt can fall into the lumen pore that the bottom is colluded in two activities, then, under spring 6 effects, it is compound in opposite directions that 5 tops are colluded in two activities, the plane dead bolt is colluded 5 lockings by two activities and can not return, but the plane dead bolt still can laterally be withdrawn lock body 2 and be shifted out the lumen pore that 5 bottoms are colluded in two activities.

The utility model also can be applicable on the door lock of many dead bolts or many bumper bars.Certainly, the utility model door lock all is fitted with lock core, key, dead bolt knob etc. when reality is used.
