Abstract

An electrically controlling door lock comprises a lock shell, a lock tongue, a continuous acting part of the spring lock body and a locking and unlocking controlling part. The locking and unlocking controlling part comprises a fixing block, one end of which is positioned on the lock shell with a hinge, and the other end of which jams the controlling block of the continuous acting part of the spring lock body. The rotation of the fixing block is controlled by an electrical device or a manual device, and the electrical device is a motor, to the rotating axis of which a plucking block is fixedly connected, while a fixing block rotating baffle which is vertical, protrudes to the left side of the plucking block, and can be plucked by the plucking block is fixedly connected to the fixing block. With the above structure, the utility model is provided with the electrical back locking function, and the safety and reliability of the electrically controlling door lock are elevated effectively. Because the electrical and mechanical efficiency of the electrically controlling door lock are elevated greatly, the power consumption is reduced; at the same time, the utility model also has the advantages of simple structure, and low failure rate, so the applicable field is very broad. The utility model can be used at the trailing-defending mutually locking safety door in the bank besides the common applications, showing more advanced service performance compared with common electrically controlling door locks.

Description

A kind of electric control door lock

(1) technical field:

The utility model relates to a kind of electric control door lock.

(2) background technology:

In order to improve safety, people have designed by Current Control and have opened, close all kinds of electric control door locks of latch mechanism, this class lock as shown in Figure 1, comprise lock housing 1, dead bolt 7, spring lock body double-action part 8 and opening, shut control section, wherein open, shut control section and comprise that end hinge is loaded on the fixture block 3 on the lock housing 1, this fixture block 3 keeps its other end to block the controll block 10 of spring lock body double-action part 8 under the effect of return spring 9, this fixture block 3 can be by electromagnetic coil 11 or manually driving lever control rotation, when needs are unblanked, need only with key by stirring manual shifting block or giving electromagnetic coil 11 energisings, allow electromagnetic actuation fixture block 3, make its certain radian that turns left, fixture block 3 can unclamp the controll block 10 of the spring lock body double-action part 8 that blocks, at this moment, under the spring action of spring lock body double-

action part

8,8 actions of lock body double-action part realize opening door lock.But this lock does not have back locking function, therefore, when its locking state, still can use key operated door lock, so the poor stability of this door lock, the existence of this problem will bring potential safety hazard to people; And use solenoid controlled fixture block rotates, and required load is big, power consumption is also bigger.

(3) utility model content:

The purpose of this utility model has been to provide the electric control door lock that a kind of security performance is good, power consumption is low.

A kind of electric control door lock, comprise lock housing, dead bolt, spring lock body double-action part and opening, shut control section, wherein open, shut control section and comprise that end hinge is loaded on the fixture block on the lock housing, this fixture block keeps its other end to block the controll block of spring lock body double-action part under the effect of return spring, this fixture block is rotated by electric device or hand gear control, described electric device is a motor, the motor level is installed in the left side of fixture block on the lock housing, realize back locking function for making the utility model, make this door lock reach good security performance simultaneously, be fixed with a shifting block that rotates in can face on the machine shaft in level, on fixture block, also be fixed with one and reach shifting block left side, vertical, thereby can be stirred by shifting block and drive the fixture block flap shutter that fixture block rotates, fixture block flap shutter bottom is lower than the shifting block surface.

Make this electric control door lock control system malfunctioning for prevent that shifting block from arbitrarily rotating on motor shaft, also be provided with the torsion spring that is used to make the shifting block return on the described motor shaft, so just, its shifting block remains on desired location in the time of can making the motor no power of this electric control door lock, thus the control system that has solved door lock malfunctioning problem easily.

The described fixture block flap shutter of this electric control door lock present position is in the root of shifting block, promptly near the machine shaft end, thereby reduced the arm of force that shifting block is stirred the fixture block flap shutter, improve the operating efficiency of motor, also fallen at the end power consumption of controlling the open and close of this door lock simultaneously.

For realizing the back locking function of this electric control door lock, the length of described shifting block is withstood for the fixture block that its termination when shifting block is in the lateral attitude just in time will be in locking state.

On described fixture block, also be fixed with one reach the shifting block upside, vertical, can limit the shifting block postive stop baffle that shifting block continues upwards to rotate, shifting block postive stop baffle bottom is lower than the shifting block surface.

The utility model is owing to adopted the structure that is provided with a shifting block in the motor shaft upper end of dialling plate one side, make this electric control door lock have the electron back lock function, after locking a door, the motor counter-rotating makes shifting block one end hold out against fixture block, at this moment, door lock then is difficult for being opened, and has improved the safety and the reliability of this electric control door lock effectively.Because the electrical efficiency and the mechanical efficiency of this electric control door lock improve greatly, thereby can accomplish low-power consumption, have reduced working voltage.Simultaneously, this electric control door lock simple in structure, fault rate is low, thereby range of application is more extensive, except that general applications, also can be used for the anti-interlocking safety door of trailing of bank, and its functional performance is superior more a lot of than traditional electric control door lock.
