Abstract

The externally controlled door lock inversely unlocking method and device has the door lock installed onto the door leaf with the key hole toward indoor. The device has key guiding channel box above the key hole and fixed on the lock casing, locating and bearing board and V-shaped spring clip mounted below the key guiding channel box, externally controlled operating rod exposed outside the lock casing and the door leaf, and key feeding hole aligned to the key guiding channel box. During unlocking, the turned key is first inserted into the key guiding channel box and made to slide to the locating and bearing board, and the externally controlled operating rod is then drawn and turned to make the key inserted into the key hole and turned inside the lock core to unlock. The present invention features the capability of avoid illegal unlocking with false key.

Description

A kind of external control falls door lock opening method and device thereof

Technical field

The present invention relates to and door matched open and close device and method for using, belong to supporting hardware products field.

Background technology

The existing mechanical door lock has drawback lock and unblanks two kinds of opening mechanisms outward.The drawback lock mechanical work principle is the people at the indoor knob that is fixed on the movable spindle chassis of door lock of twisting, and makes the deflection of movable chassis, through linkage dead bolt is drawn in the door lock housing and by pintle hook lock and blocks, and this moment can be with Men Lakai.When door was shut, the removable pin that is arranged in dead bolt backed down pintle hook lock because of knocking door case toward moving, and dead bolt stretches out outside the door lock housing under the effect of back-moving spring again, thereby door lock is lived.Because back-moving spring one end hangs on the door lock housing, the other end hangs on the movable spindle chassis, therefore, the people when knob rotates movable spindle chassis back-moving spring will be reversed when twisting, produce the elastic force that movable chassis and dead bolt are resetted.

Outer unlocking mechanism operating principle is that door lock core passes door leaf and lock core hole towards outdoor; The people is injecting key in the lock core hole outdoors; Twist lock core, the pulling block on the lock core is stirred pulling pin of movable chassis, makes the deflection of movable chassis; Through linkage dead bolt is drawn in the door lock housing and by pintle hook lock and to block, thereby can door be pushed open.

Though the existing mechanical door lock is simple in structure, sturdy and durable, low cost of manufacture, installation are easy, theftproof performance is poor, and its lock core is easy to twisted with the skilled unlocking method by the burglar, thereby easily door is opened.That is to say that for the robber of mastering a skill property method for unlocking, mechanical door lock is nothing but an empty shell.Also occurred the organizations and individuals of some specialty professor skilled unlocking methods in recent years, the situation is tense more to make social security, and the larceny case of crossing the threshold increases sharply, and serious threat is lived and worked in peace and contentment to people's.

Occurred some at present and can discern the electronic lock of fingerprint, pupil, opened the door and go into though can effectively prevent robber's operation technique property method for unlocking, manufacture craft costs an arm and a leg again, still can not popularize and promote the use of.

Summary of the invention

The purpose of this invention is to provide a kind of external control and fall door lock opening method and device thereof, accomplish both to improve the theftproof performance of mechanical door lock, simple again.

Technical scheme is with the mechanical door lock upside-down mounting, and promptly lock core does not pass door leaf and lock core hole is installed towards indoor direction.Fixing key guide runner box on the door lock housing, key slide guide box are positioned at front upper place, the lock core hole outside.The key that has two fingers aiming at key guide runner box to stretch on the door leaf is sent into the hole.The V-type spring clip that locating support plate and opening are aimed at lock core hole is installed in key guide runner box below, be the shank of the key when inserting key guide runner box forward when key pours into, but crossheading is slipped on the locating support plate and the shank of the key is positioned in the middle of the V-type spring clip opening.The external control action bars that links to each other with the V-type spring clip passes the door lock housing and door leaf exposes outdoors.The external control action bars both can spur the V-type spring clip and make it to clamp the shank of the key and move along locating support plate, also can drive the rotation of V-type spring clip, even the key deflection of being clamped by the V-type spring clip.

The step of unblanking is following:

1, falling to take key to send into the hole through key with two fingers inserts key in the guide runner box.

2, under the guide runner box, slide on the locating support plate and the shank of the key when falling within the middle of the V-type spring clip opening when key, toward pulling out the external control action bars outdoors, clamp and promote the shank of the key, make in the key insertion lock core hole through the V-type spring clip with hand.

3, twist the external control action bars with hand, drive key deflection through the V-type spring clip, door-lock opening.

In order to have prevented that people's malice from putting into foreign material, occupying locating support plate and influence owner and unblank, the present invention is designed to the portable plate that can rotate around the shaft with locating support plate, and the base plate action bars that links to each other with rotating shaft then passes door lock housing and door leaf and exposes outdoors.Be equipped with back-moving spring on the base plate action bars.The people is twisting the base plate action bars outdoors, locating support plate is put by horizontal direction become the vertical direction storing, thereby the foreign material on it are shaken off on the ground.

In order to keep the original drawback lock function of mechanical door lock, the present invention is provided with the internal control action bars.The internal control action bars is set on the door lock housing, on the movable spindle chassis of door lock the sprocket wheel that links to each other with internal control action bars sprocket wheel through chain is housed.The people is at the indoor internal control action bars of twisting, and can make the deflection of movable chassis and with door-lock opening.

Compared with present technology, the present invention has following characteristics:

1, theftproof performance is high, effectively prevents burglar's operation technique property method for unlocking.

The present invention can not directly contact the robber with lock core, thus the robber can't with see, listen, touch, skilled unlocking method such as cover is door-lock opening.If the burglar uses from bitting and inserts the runin of key guide runner box; Profile of tooth has not to just not opening slightly; The key that runin is used then can't be taken back, and this point has fundamentally been broken off the thought of burglar with the key runin, because he does not have so much runin key and plenty of time to attempt.

2, simple, use cost is low, is easy to popularize and promote the use of.

The present invention need not to change the internal construction of existing machinery door lock; Just with the upside-down mounting of existing mechanical door lock on door leaf, the door lock housing outside or the position, space increase parts such as key guide runner box, locating support plate, V-type spring clip and external control action bars and get final product, so simple; Be applicable to existing door lock repacking; And the repacking cost is low, meets huge numbers of families' needs, helps popularizing and promoting the use of.
