Description

A kind of remote-controlled theft-proof door lock

Technical field

The utility model belongs to the safe-guard door lock technical field, relates to a kind of remote-controlled theft-proof door lock.

Background technology

Existing safe-guard door lock generally all is to adopt key unlocking, but key is replicated easily, can also use unlocked by universal key simultaneously, and security performance is not high, also comparatively bothers and all must open the lock with the key when entering at every turn.What is more, and some person of making trouble clamp-ons glue in the lockhole, and door can't be opened, and disturbs so the people is carried on a shoulder pole.

A kind of door lock remote control anti-theft device of CN200620016066.7 is disclosed in Chinese patent literature at present, comprise lock housing and lock pin, described lock pin connects a tooth bar, fix the track of a support tooth bar on the lock housing, so that tooth bar is along slide, on the lock housing by one fix one with the tooth bar meshed gears, a remote-receiver is set in the lock housing, remote-receiver connects also controls a motor, and machine driving is connected between the output shaft of motor and the gear.Two ends near tooth bar on the lock housing are provided with a stop respectively.Stop is connected with the remote-receiver signal.

The weak point of this kind door lock remote control anti-theft device mainly contains:

(1) to be connected be with several meshing deceleration transmission that realize to gear to this machine driving of the motor output shaft of this kind door lock remote control anti-theft device and gear.If it is just much of that directly gear set to be exported drive tooth bar commentaries on classics half-turn on motor shaft, this required procedure of processing is more, spends also higher.

(2) slip of tooth bar also is necessary for the track that tooth bar slides has also increased manufacturing procedure.

(3) gear and tooth bar, the processing of track cooperates all must have certain machining accuracy, all is slidingly matched.In door lock, do not indicate the part of locking tooth bar.So described lock pin can prize to get back in the lock housing according to reason and go with some thin slices.

The utility model content

The purpose of this utility model provides a kind of simple in structure." opening " and " pass " with remote-control signal transmitter control remote-controlled theft-proof door lock.In case after the locking, just can not be prized by thin slice.Go up the remote-controlled theft-proof door lock that does not just leave lockhole if be installed in door simultaneously.

The technical scheme that realizes the utility model purpose is:

A kind of remote-controlled theft-proof door lock, comprise lock housing, lock pin and piston driver with a kind of rigidity telescopic piston, described lockpin sleeve is located on the axle head of described rigidity telescopic piston, and the locking key on the lock pin is arranged on and is matched in clearance in the side direction square hole of lock housing; Described piston driver comprises support, being arranged on being used on the described support provides the motor of power, have cavity on the motor shaft and female thrust axis is set in described cavity Gu axle fixes on, the double-screw bolt that is provided with external screw thread and keyway as described rigidity telescopic piston, with the pin key that is fixed on the described support and matches with keyway on the described double-screw bolt, the internal thread in the external screw thread of described double-screw bolt and the cavity of described thrust axis matches.

Described thrust axis adopts shaft coupling to be connected with described motor shaft, and adopts bearing that described thrust axis is arranged on the described support.Stroke with the travel control device control piston.

The utility model can be controlled the flexible of rigidity telescopic piston easily by the circuit of control piston drive unit, and then controls described remote-controlled theft-proof door lock " opening " and " pass ".

The utility model can also be provided with the remote signal receiver of the electrical connection of remote-control signal transmitter and described piston driver, and described remote signal receiver is controlled the flexible of rigidity telescopic piston in the described piston driver by receiving described remote-control signal transmitter transmitted radio signal.Locking key entering and coming out in lock housing on the flexible lock pin just of described piston.

The positive effect that the utlity model has:

1. the utility model is simple in structure, and processing cost is light, and employing internal and external threads easy to use cooperates, and becomes straight line by circular motion and moves back and forth.In a single day it just stop and can not be prized.

2. just do not have lockhole on the door if be installed in, make the robber have no way of doing it.

3. come control gate " opening " and " pass " with remote controller, factor control signal transmits and does not generally have duplication code.

4. " opening " and " passs " of control gate and within the specific limits, particularly about floor downstairs just can unblank on also unnecessary.
