Abstract

The invention discloses lock cylinder protection device. The device comprises a fixed plate, a movable door, billiards and a key inserted-bar, wherein the fixed plate is riveted or soldered on the periphery of a lock cylinder; the movable door covers the front of the key hole of the lock cylinder; a plurality of consistent billiard holes are formed in the movable door and the fixed plate, and the billiards are clamped between the movable door and the fixed plate under the action of springs, so that the movable door cannot be opened; the key inserted-bar is formed by inserted bars which do not have equal length and have the same number as that of the billiard holes, and the length of each inserted bar and the length of the corresponding billiard in the billiard hole of the fixed plate are equal to the length of each billiard hole of the fixed plate and the thickness of a magnetic lock hole plate, so that the key inserted bar is inserted into the lock hole and presses the billiards of the fixed plate downward, the billiards of the fixed plate are used for pressing billiards of the movable door back into the movable door, the contact surface of billiards and the contact surface between the fixed plate and the movable door become planes without blocking, and the movable door is opened under the action of opening the device.

Description

A kind of lock pin protecting equipment

One. technical field

The present invention relates to a kind of lock pin protecting equipment, before lock core keyhole, specifically install a kind of protection device additional.

Two. background technology

At present, it is common to use a word or cross lock core very not firm, open an account easily, technology unlocking base in a minute Originally can open, be opened with strong instrument of turning round, just can open within even more have more than is needed ten seconds, and theftproof lock with high content of technology, because of structure Make complexity, cost is too high, consumer's difficult to accept is made on price, so being difficult to popularization.

Three. content of the invention

The invention discloses a kind of lock pin protecting equipment, including fixed plate, dodge gate, magnetic lock eye plate, fixed plate pellet, Portable plate pellet and key inserted link；Described fixed plate rivet or be weldingly fixed on lock core surrounding, dodge gate blocks in lock core key Before keyhole, before lock core keyhole, install one barrier additional；Described dodge gate is provided with consistent pellet with fixed plate Hole, marble hole is more, and change probability is bigger, and mutual opening rate gets over bottom；When closing dodge gate, the pellet of dodge gate is in the effect of spring Stretch on lower and be stuck between dodge gate and fixed plate, at this moment dodge gate and fixed plate are securely joined with integral it is impossible to open；Described Key inserted link is made up of the unequal inserted link consistent with pellet hole number of length, and the length of every inserted link adds corresponding fixation The length of plate pellet in the hole pellet be equal to fixed plate marble hole length lock eye plate thickness, so, when with key inserted link from Hole of button injects, and the pellet of fixed plate is pressed down, the pellet of fixed plate just pushes back the pellet of dodge gate in dodge gate completely, At this moment, the contact surface of the contact surface between pellet and fixed plate and dodge gate just becomes the plane not stopped, dodge gate is certainly In the presence of dynamic opening device, automatically open up, the lock core keyhole blocking just has revealed out, at this moment just can be facilitated with key A ground lock is normally opened.

The effect of described magnetic lock eye plate is it is simply that the pellet absorption in fixed plate in pellet in the hole, and hole of button Diameter is less than the diameter of pellet；Be provided with semi-circular lintel in the junction of fixed plate and dodge gate, so, when dodge gate open and During closing, the pellet of dodge gate can not eject.

Simple structure of the present invention, with low cost, structural strength is high, plays double protection to existing lock core, has very The big market development is worth.

Four. brief description

It is described further below in conjunction with the accompanying drawings

Fig. 1：It is sectional arrangement drawing of the present invention

Fig. 2：It is key schematic diagram of the present invention

In figure：(1) fixed plate, (2) dodge gate, (3) magnetic lock eye plate, (4) fixed plate marble hole, (5) portable plate pellet Hole, (6) fixed plate pellet, (7) portable plate pellet, (8) activity flat spring, (9) automatic open device, (10) hole of button, (11) Lintel, (12) key inserted link, (13) key handle.

4th, embodiment

Specific embodiments of the present invention are：In Fig. 1, Fig. 2, magnetic lock eye plate (3) is welded on fixed plate (1) top, And inject key inserted link (12) in hole of button (10), then fixed plate pellet (6) is put into fixed plate marble hole (4) in proportion Interior, make fixed plate marble hole (4) surface become a plane, automatic open device (9) is pressed into movable door pillar two ends, then work Dynamic door (2) is combined with fixed plate (1), dodge gate spring (8) and dodge gate pellet (7) is sequentially loaded into pellet in the hole, by activity Door (2) buckles and completes the program.

Claims

1. a kind of lock pin protecting equipment, including fixed plate, dodge gate, pellet and key inserted link it is characterised in that：Dodge gate (2) It is provided with consistent marble hole with fixed plate (1), pellet (5) is in the presence of spring (8) dodge gate (2) and fixed plate (1) Be stuck securely, when being injected from hole of button (10) with key inserted link (12), pellet (5) down, pellet (5) with movable The contact surface of door (2) and fixed plate (1) just becomes the plane not stopped, dodge gate (2) is opened.

2. a kind of lock pin protecting equipment according to claim 1 it is characterised in that：Key inserted link (12) be by with marble hole Quantity is consistent, but the unequal inserted link of length forms, and the length of every inserted link adds in corresponding fixed plate marble hole (4) The length of pellet (6) adds the thickness of magnetic lock eye plate (3) equal to the length of fixed plate marble hole (4).

3. a kind of lock pin protecting equipment according to claim 1 it is characterised in that：Keyhole plate adopts magnetic steel plate to make, And hole of button (10) diameter is less than billiards diameter, so the pellet of pellet in the hole can be adsorbed in magnetic lock eye plate lower end.

4. a kind of lock pin protecting equipment according to claim 1 it is characterised in that：Fixed plate (1) is joined with dodge gate (2) Place, is provided with semi-circular lintel (11), so when dodge gate (2) is opened, the pellet of pellet in the hole can not eject.
