Description

A kind of electronic lock body

Technical field

This utility model relates to a kind of electronic lock body.

Background technology

Electronic lock body is a kind of to come control circuit or chip operation by input validation information, thus control mechanical switch complete to unblank, the electronic product of locking task.

The dead bolt of existing electronic lock body is all rigidly connected with driving motor, thus cause dead bolt cannot promote compression dead bolt by artificial when stretching out, this exists for a problem, during once lock damages, dead bolt is just at the state stretched out, so door just cannot be closed, therefore can only use picking lock or etc. to be repaired, bother very much.

In consideration of it, the present inventor develops a kind of electronic lock body for this, effectively solving the problems referred to above, this case thus produces.

Utility model content

A kind of electronic lock body that this utility model provides, simple in construction, low cost, dead bolt can push in lock housing from front by hand-operated forced.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of electronic lock body, including lock housing, and driving motor, slide block, compression spring and the dead bolt being arranged in lock housing, forming slide block slot in lock housing, slide block is arranged in this slide block slot, drives motor and slide block connects and drives slide block along slide block slot slide anteroposterior, lock tongue slot is offered in slide block, dead bolt is T-shaped, and the T-shaped bottom of dead bolt is placed in lock tongue slot and can be movable along lock tongue slot, is provided with T-shaped bottom is pressed on the compression spring on lock tongue slot antetheca between this T-shaped bottom and lock tongue slot rear wall.

It is formed with slide rail on described slide block slot, slide block is formed corresponding rail groove, make slide block accurately along slide block slot slide anteroposterior by the cooperation of rail groove and slide rail.

It is mounted on balancing spring between described slide block and driving motor and slide block slot antetheca.

Connected by screw body between described slide block and driving motor.

Fixedly mounting thread spindle on the motor shaft of described driving motor, the through hole stretched into for thread spindle offered by the rear wall of slide block, offers the screw body described in the screwed hole with threaded shaft fits, thread spindle and screwed hole composition in this through hole.

Vertical slot also offered by the rear wall of described slide block, U-shaped jump ring it is plugged with in slot, U-shaped jump ring is plugged in the screw thread of thread spindle, and thread spindle rotates and makes U-shaped jump ring deform, and the U-shaped jump ring tight abutment after deformation is relatively fixed with holding thread spindle and slide block in the threaded side wall of thread spindle.

After using such scheme, this utility model simple in construction, the slide block being offered lock tongue slot by inside connects driving motor and dead bolt, and dead bolt is pressed on the antetheca of lock tongue slot by compression spring, therefore when artificially forcing to promote dead bolt from the front of dead bolt, dead bolt will overcome the active force of spring, continue compression spring, thus be pushed in lock housing by dead bolt.Therefore once lock damages, then can pushing lock cylinder, the lock core after then pushing fixes, and can continue to close the housed devices such as door.

Label declaration

Lock housing 1, slide block slot 11, slide rail 12, drive motor 2, thread spindle 21, slide block 3, rail groove 31, rear wall 32, through hole 33, slot 34, U-shaped jump ring 35, lock tongue slot 36, compression spring 4, dead bolt 5, T-shaped bottom 51, balancing spring 6.

Detailed description of the invention

In order to the technical solution of the utility model is explained further, below by specific embodiment, the utility model is elaborated.

As Figure 1-3, it is a kind of electronic lock body of this utility model announcement, including lock housing 1, and driving motor 2, slide block 3, compression spring 4 and the dead bolt 5 being arranged in lock housing 1.

Forming slide block slot 11 in lock housing 1, slide block 3 is arranged in this slide block slot 11.Drive motor 2 and slide block 3 to connect, and drive slide block 3 along slide block slot 11 slide anteroposterior.Wherein it is formed with slide rail 12 on slide block slot 11 inwall, slide block 3 is formed corresponding rail groove 31, by rail groove 31 and the cooperation of slide rail 12, make slide block 3 accurately along slide block slot 11 slide anteroposterior.

Owing to slide block 3 is easily generated the trend of inclination during sliding, the friction causing slide rail 12 and rail groove 31 is excessive.In order to reduce abrasion and reduce the power of driving motor 2, it is mounted between slide block 3 and driving motor 2 and slide block slot 11 antetheca ensureing the balancing spring 6 that slide block 3 is not skewed, the power on slide block 3 is acted on by these two balancing springs 6, increase the stability that slide block 3 runs, thus reduce the frictional force between slide rail 12 and rail groove 31.Balancing spring 6 still prevents slide block 3 and slides excessive and touch and forward wall before and after slide block slot 11 to simultaneously, and prevents following thread spindle 21 from departing from slide block 3.

Connected by screw body between slide block 3 and driving motor 2.Concrete, the motor shaft driving motor 2 fixedly mounts thread spindle 21, the through hole 33 stretched into for thread spindle 21 offered by the rear wall 32 of slide block 3, the screwed hole (not shown in common structure figure) coordinated with thread spindle 21 is offered, by constituting screw body by this thread spindle 21 and screwed hole in this through hole 33.

Owing to certain gap is joined and existed in the transmission between screw thread, therefore when motor stalling, slide block can play forward, slide block is caused to run shakiness, for solving this problem, as Figure 2-3, vertical slot 34 offered by rear wall 32 at slide block 3, U-shaped jump ring 35 it is plugged with in slot 34, U-shaped jump ring 35 is plugged in the screw thread of thread spindle 21, when thread spindle 21 rotates, U-shaped jump ring 35 will be made to deform, U-shaped jump ring 35 after deformation by tight abutment in the threaded side wall of thread spindle 21, thus keep thread spindle 21 and slide block 3 to be relatively fixed, drive motor 2 when shutting down, slide block can be avoided to produce certain play, increase slide block traveling comfort and accuracy.

Offering lock tongue slot 36 in slide block 3, dead bolt 5 is T-shaped, and the T-shaped bottom 51 of dead bolt 5 is placed in lock tongue slot 36, and can move forward and backward along lock tongue slot 36.Between this T-shaped bottom 51 and lock tongue slot 36 rear wall, compression spring 4 is installed, by this compression spring 4, T-shaped bottom 51 is pressed on lock tongue slot antetheca.

The present embodiment simple in construction, the slide block 3 being offered lock tongue slot 36 by inside connects driving motor 2 and dead bolt 5, and dead bolt 5 is pressed on the antetheca of lock tongue slot 36 by compression spring 4, therefore when artificially forcing to promote dead bolt 5 from the front of dead bolt 5, dead bolt 5 will overcome the active force of compression spring 4, continue compression spring 4, thus dead bolt 5 is pushed in lock housing 1.Therefore once lock damages, so can dead bolt 5 be pushed in lock housing 1, then the dead bolt 5 after being pushed by adhesive tape etc. is fixed, can continue to close the housed devices such as door, the particularly suitable antitheft door with multiple dead bolt, it is also suitable the drawer that can allow not lock, and optimizing further thus reduce the power consumption of electronic lock by structure.

These are only preferred embodiment of the present utility model, the not restriction to protection domain of the present utility model.All equivalent variations done according to the mentality of designing of this case, each fall within the protection domain of this case.
