Abstract

The invention relates to an automatic locking lock body which comprises a lock body housing, a main lock tongue plate and an adhering plate, wherein the main lock tongue plate is arranged in the lock body housing and is contacted with the lock body housing through the elasticity of a first spring; and moreover, a tongue plate head stretches out of the lock body housing; a hinge pin is fixed to the tongue plate head, and a locking key which can slide is sleeved on the hinge pin; the locking key and the hinge pin are provided with second springs; idler wheels are clamped into the locking key and face towards the adhering plate; and the adhering plate is fixed to a door frame and matched with the main lock tongue plate. The automatic locking lock bod has the beneficial effects that 1, the lock tongue of the lock body is longer and bigger than that of other small lock bodies, and the quality and the stopping performance are more reliable; the automatic locking mode that the idler wheels are contacted with the door frame is adopted; the lock tongue can be longer; and 2, the automatic locking lock body is resistent to inserting, has performance of stopping and preventing prizing up, and can be automatically locked.

Description

A kind of lock body that automatically locks

Technical field

The present invention relates to the lock body technical field, relate in particular to a kind of lock body that automatically locks.

Background technology

Existing little lock body is basically take oblique spring bolt as main on the market, and the length of stretching out is short and little, is again to tip dead bolt in by the doorframe limit, and such dead bolt can't be done length, also causes the dead bolt of at every turn closing the door all in friction, can be dumb without oil, refuel and the spot clothing.

Summary of the invention

The object of the invention is to overcome the deficiency that prior art exists, and a kind of easy and simple to handle, lock body that automatically locks that theftproof is good is provided.

The objective of the invention is to finish by following technical solution, it comprises lock body shell, master lock hyoplastron, paster, described master lock hyoplastron places in the lock body shell, and the elastic force by the first spring between master lock hyoplastron and lock body shell contacts, and the hyoplastron head stretches out in lock body shell; This hyoplastron head is fixed with pivot pin, overlaps to have on this pivot pin and slidably goes up locking key, and locking key and pivot pin are provided with the second spring on this, have snapped in roller in the upper locking key, and this roller is toward the paster place, and described paster is fixed on the doorframe, and this paster and master lock hyoplastron match.

As preferably, be provided with shift fork in the described lock body shell, the retaining point on the shift fork contacts with opening point on the master lock hyoplastron, and the pulling point on the shift fork contacts with the die stop on the master lock hyoplastron.

As preferably, be provided with locking key in the described lock body shell, the keyed end on the locking key contacts mutually with tab on the master lock hyoplastron, and the solution snap close on the locking key pushes away a little with release in the upper locking key and contacts.

Beneficial effect of the present invention is: 1, this lock body is longer and large than the dead bolt of other little lock bodies, and is more reliable on quality and the retaining, and adopts roller to touch the doorframe mode that automatically locks, and also can do dead bolt longlyer; 2, anti-plug, retaining pick-proof automatically lock.

Label in the accompanying drawing is respectively: 1, lock body shell; 2, paster; 3, master lock hyoplastron; 4, roller; 5, upper locking key; 6, locking key; 7, shift fork; 8, pivot pin; 9, the first spring; 10, the second spring; 3-1, opening point; 3-2, tab; The 3-3 die stop; 3-4, hyoplastron head; 5-1, release push away a little; 6-1, keyed end; 6-2 separates snap close; 7-1, retaining point; 7-2, pulling point.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is done detailed introduction: as shown in drawings, the present invention includes lock body shell 1, master lock hyoplastron 3, paster 2, described master lock hyoplastron 3 places in the

lock body shell

1,1 elastic force by the first spring 9 of master lock hyoplastron 3 and lock body shell contacts, and hyoplastron head 3-4 stretches out in lock body shell 1; This hyoplastron head 3-4 is fixed with pivot pin 8, overlaps to have on this pivot pin 8 and slidably goes up locking key 5, and locking key 5 is provided with the second spring 10 with pivot pin 8 on this, snapped in roller 4 in the upper locking key 5, this roller 4 is toward paster 2 places, and described paster 2 is fixed on the doorframe, and this paster 2 matches with master lock hyoplastron 3.

Be provided with shift fork 7 in the described lock body shell 1, the retaining point 7-1 on the shift fork 7 contacts with opening point 3-1 on the master lock hyoplastron 3, and the pulling point 7-2 on the shift fork 7 contacts with die stop 3-3 on the master lock hyoplastron 3.Be provided with locking key 6 in the described lock body shell 1, the keyed end 6-1 of locking key 6 and tab 3-2 on the master lock hyoplastron 3 contact mutually, and the solution snap close 6-2 on the locking key 6 pushes away a 5-1 with the release of upper locking key 5 and contacts.

Opening process: rotation shift fork 7, the opening point 3-1 on the pulling point 7-2 pulling master lock hyoplastron 3 on the shift fork 7 does transverse movement.This moment, the tab 3-2 that withstands on the master lock hyoplastron 3 of keyed end 6-1 of locking key 6 locked master lock hyoplastron 3, made it not eject master lock hyoplastron 3 under the effect of the elastic force of the first spring 9, finished unlatching.

The process of locking: when roller 4 is subjected to External Force Acting, transverse movement is done in locking key 5 in the drive, make the release of locking key 5 push away a 5-1 and promote solution snap close 6-2 rotation on the locking key 6, thereby make the go out of lock locking of keyed end 6-1 of key 6 of tab 3-2 on the master lock hyoplastron 3, master lock hyoplastron 3 ejects under the elastic force effect of the first spring 9, finishes and locks.Retaining point 7-1 on the shift fork 7 has withstood the die stop 3-3 on the master lock hyoplastron 3, makes master lock hyoplastron 3 have stopping function.

The present invention is not limited to above-mentioned embodiment, no matter do any variation in its shape or material formation, every employing structure design provided by the present invention all is a kind of distortion of the present invention, all should think within protection domain of the present invention.
