Description

Lock head capable of preventing technical opening

Technical Field

The utility model relates to a prevent tapered end that technique was opened belongs to tapered end technical field.

Background

The technical unlocking is an unlocking technology which does not use a key configured by the lock and does not use violent methods such as drilling, welding, cutting, frying, twisting and the like, but adopts a certain tool and opens the lock by a special method. The prior technical unlocking method mainly comprises the following steps: 1. unlocking by a hook lock tool; 2. unlocking by a gun collision and tooth collision method; 3. unlocking the software object by an extrusion method; 4. unlocking by a master key method.

Technical unlocking can bring certain convenience to people, for example, when people drop a key or put the key in a locked house or box, the door cannot be opened, a special technician can be asked to open the lock by a technical unlocking means, the lock and the door are not damaged, and convenience is brought to people. However, the technical unlocking brings great instability factors to the society, for example, if the technical unlocking is used by some thieves, the property of many people is greatly threatened or lost, and even the life is injured.

The B-level lock with the highest safety level in the anti-theft lock standards has the technical opening prevention time of more than 5 minutes and the shortest time among various safety performance indexes, so that the existing lock head has the defects in the technical opening prevention safety performance and has a gap with the safety requirements of life of people. In order to overcome the defects of the existing lock head structure form in the aspect of preventing technical opening, patent document 201110992664.1 discloses a spring lock head for preventing technical opening, which adopts the design of transmitting unlocking torque force after dislocation between an inner lock cylinder and an outer lock cylinder during normal unlocking to improve the performance of preventing technical opening, but the lock head with the structure can realize the torque force transmission between the inner lock cylinder and the outer lock cylinder by other methods at the locking initial position, has the possibility of being opened by the dislocation technology, and has the defects in the aspect of preventing technical opening.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a tapered end that prevents the technique and open is provided to above-mentioned prior art, fundamentally has stopped the possibility that "dislocation" technique was opened, and the security performance is higher.

The utility model provides a technical scheme that above-mentioned problem adopted does: a lock head for preventing technical unlocking comprises a lock shell and a lock core positioned in holes at two sides of the lock shell, wherein the middle part of the lock shell is provided with a thumb wheel which can rotate freely, the lock core and the thumb wheel are connected through a transmission mechanism, a plurality of spring holes corresponding to the teeth on the key are arranged on the lock core and the lock shell, the key hole on the lock core is communicated with the marble hole, round head marbles, flat head marbles, marble springs and sealing marbles are respectively arranged in the marble hole in sequence, the round head marble is arranged in the marble hole of the lock core, the marble spring and the sealing marble are arranged in the marble hole of the lock shell, the flat head marble is arranged in the lock core marble hole and the lock shell marble hole at the same time, the lock core marble hole is structurally provided with a step type and a straight hole type, the number of the straight hole type lock core marble holes is not less than 1, when the flat head marble in the step type lock core marble hole inclines, the step type lock core marble hole has a limiting effect on the marble.

The diameter of the lower end of the stepped lock cylinder pin hole is larger than that of the upper end of the stepped lock cylinder pin hole, and the flat head pins in the stepped lock cylinder pin hole and the lock shell pin hole are I-shaped flat head pins.

The transmission mechanism comprises a pair of transmission parts and a pair of pad heads, the transmission parts are respectively arranged in the thumb wheel in a penetrating way, the pad heads are respectively arranged on the outer sides of the transmission parts, and the pad heads are respectively arranged in the lock core.

Compared with the prior art, the utility model has the advantages of: the lock with technically opened lock core has improved pin hole structure to prevent pin from being pulled out of lock shell, and this can raise the safety of lock and protect people's property.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 2, the lock of this embodiment for preventing technical unlocking includes a lock case 3 and a lock core 10 located in two side holes of the lock case 3, a thumb wheel 4 capable of rotating freely is disposed in the middle of the lock case 3, a driving member 9 and a pad 8 are disposed between the lock core 10 and the thumb wheel 4, a pair of driving members 9 is disposed in the thumb wheel 4, the outside of the driving member 9 is respectively provided with the pad 8, the pad 8 is disposed in the lock core 10, 5 ball holes corresponding to the teeth on the key are disposed on the lock core 10 and the lock case 3, the key hole on the lock core is communicated with the ball holes, a round head ball 7, a flat head ball 5, a spring 2 and a sealing ball 1 are disposed in the ball holes on the lock core, the round head ball 7 is disposed in the ball hole on the lock core, the ball spring 2 and the sealing ball 1 are disposed in the lock case, when the key is inserted into the lock core. The flat head marble 5 is arranged in the lock core marble hole and the lock shell marble hole simultaneously, the structure of the lock core marble hole is provided with 4 steps and 1 straight hole, the flat head marble 5 in the step lock core marble hole is an I-shaped flat head marble 6, the diameter of the lower end of the step lock core marble hole is larger than that of the upper end of the step lock core marble hole, the inserting piece is inserted into the lock core keyhole, a rotating force is applied, the lock core 10 is inclined at the moment, when the I-shaped flat head marble 6 is inclined together, the step in the step lock core marble hole plays a limiting role on the I-shaped flat head marble 6, so that the marble cannot be pulled out of the lock shell, and the lock head.
