Abstract

The utility model relates to a fast retractable explosion-proof four-section lock, which is provided with a lock core and a plate bar, wherein, the plate bar is connected to an armature spring axle which is fixed to a lock shell. An anchoring spring and a spring are sheathed to the armature spring axle; a deflector rod is fixed on a bolt which is connected to the lock shel through an axial pin; a shifting fork rides on the lock and is fixed to the bolt by means of a taper spring; a torsion spring is fixed to a casing through the torsion spring; the armature spring and a slim axle are slidingly matched; two ends of the shifting fork are symmetrical and form concavity; the lock core is provided with an outer ring; the outer ring is provided with holes, and the inner part of the outer ring is provided with a positioning pin. The utility model has the characteristics of convenient installation, good safety performance, simple and reasonable structure, low failure rate, etc.

Description

The explosion-proof four-section lock of quick-expansion

The utility model relates to a kind of door locking device--do not have and draw the explosion-proof four-section lock of a quick-expansion.

Prior art, all turn the key in the lock, open the door without rotating handles, in use, the user when flurried, can not find key urgent again, cause the escape difficulty, consequence is hardly imaginable certainly, and the oblique tongue of locking in the prior art in addition all has only a direction, in the time of need turning to, palpus disassemble internals, turn to, bring difficulty to installation, the disassemble internals causes the damage of inner body easily, their core divides fixed and movable two classes, the former has limited the thickness that door is installed, and this is that installation can only be catered to the thickness of fixed gate because core is to be fixed on to lock, the latter is movable, it will look the thickness of door when mounted, and the Chang Yaoyong saw amputates the driver blade of unnecessary core back, and this gives to install and makes troubles again.

The purpose of this utility model is effectively to overcome the tripartite planar defect of above-mentioned existence, proposes a kind of nothing and draws the explosion-proof four-section lock of a quick-expansion.

Technical solution of the present utility model:

Lock core is arranged, plate handle 1, plate handle 1 is connected on the tongue axle 5, tongue axle 5 is fixed on the lock housing 15, fastening spring 2, spring 3 are enclosed within on the tongue axle 5, driving lever 6 is fixed on the dead bolt 8, dead bolt 8 connects lock housing 15 by pivot pin 14, and shift fork 11 straddles on the lock 8, and is fixed on the dead bolt 8 by tower spring 12, torsion spring 10 is fixed on the housing by torsion axis 9, tongue 7 is sliding fits with thin axle 16, and two symmetries of the shift fork 2 that is connected with lock housing are concavity, and an outer ring is arranged on the lock core, seven holes that can regulate the lock core stroke are arranged on this outer ring, a spring holder is arranged in this outer ring.

Advantage of the present utility model:

1, Du Te fast rotational handle adopts 180 ° of fast automatic turning to, the location, have in handle the inside to be the concavity design, want 360 ° to turn to and subtracted half with original, four sections are opened the door entirely on handle, open the door easily in the inside, just in case also escape easily of emergency is arranged.2, tiltedly tongue turns to only need externally use and pliers is pulled out oblique tongue just can turn to, and is convenient to installation.3, Du Te locked groove exposes the design of afterbody, just as the door shelves expose afterbody as can be known door lock whether shut, have only oblique tongue shelves to live door and just know and lock, improved security performance.4, install easily, look the thickness of door, press the other button of core, transfer to the thickness 32-50 mm of door, the direction of going back visuable door, external-open, in open, pull out oblique tongue and just turn to and can install.5, total simplicity of design, reasonable, direct transmission greatly reduces fault rate during use.

Accompanying drawing is a structural representation of the present utility model.

Further specify the course of work of the present utility model below in conjunction with accompanying drawing:

Locking is fixed on the body, by handle or key rotary locking cylinder, is the whole overall process that opens or closes lock.Specifically, at indoor rotating handles, start dead bolt 8, dead bolt 8 drives shift fork 11, drives driving lever 6 by bearing pin 14, and tongue axle 5 is given in transmission, makes tongue 7 actions, finishes the Push And Release of lock.
