Abstract
The utility model discloses an anti-theft lock which comprises a lock box, a control circuit box and a remote controller. A lock tongue playing a locking role is mounted in the lock box; an electromotor is also mounted in the lock box; the lock tongue is driven by the electromotor to move; the electromotor is electrically connected with the control circuit body; and the remote controller is used for controlling the corotation and the reversion of the electromotor through controlling the circuit box, thereby controlling the extension and the retraction of the lock tongue. The movement of the lock tongue in the door lock is controlled by the remote controller in the utility model, so that the keyhole and the key of the traditional door lock are eliminated and the unlocking performed by usingother unlocking tools through the keyhole is prevented, thereby playing a good anti-theft role.
Description
Technical field
The utility model relates to door lock.
Background technology
The structure of common door lock generally comprises lock box, tapered end and key, and knob and the dead bolt that plays the locking effect are arranged on the lock box, and lock core is arranged in the tapered end, is connecting driver blade on the lock core, in the knob on the driver blade insertion lock box.When key inserts in the lock core, twist lock core, can drive knob by driver blade, thereby drive dead bolt.The lockset of this structure owing to have keyhole, except key, be easy to unblank by keyhole to other unlocking tools, so security performance is not high.
The utility model content
The purpose of this utility model provides a kind of door lock that does not have keyhole.
For achieving the above object, the technical solution of the utility model is: a kind of theftproof lock, comprise lock box, control circuit box and remote controller, the dead bolt of locking effect has been housed in the lock box, motor also is housed in the lock box, and the motion of dead bolt is by Motor Drive, is electrically connected between motor and the control circuit box, remote controller is controlled the rotating of motor by the control circuit box, thereby controls stretching out and withdrawal of dead bolt.
Motor is fixed on the dead bolt, and the output of motor is equipped with gear, is fixed with tooth bar in the lock box, and wheel and rack is meshing with each other.
On the circuit between motor and the control circuit box magnetic switch is set, magnetic switch is a normally open, connects circuit when magnetic switch is subjected to magneticaction.
Oblique tongue also is housed on the lock box, and tiltedly tongue is provided with the shifting block that stretches out lock box, and shifting block is used for manually stirring oblique tongue; Tiltedly be provided with link gear between tongue and the dead bolt, when unblanking, the dead bolt withdrawal can drive oblique tongue withdrawal.
Link gear is the push rod of stirring oblique tongue that is arranged on the dead bolt, and push rod can move along its axis, and the lock box at close dead bolt rear portion is provided with jacking block, push rod is provided with the inclined-plane, when the dead bolt withdrawal, when jacking block is run on the inclined-plane of the push rod on the dead bolt, push rod moves vertically, can discharge oblique tongue.
The beneficial effects of the utility model are, it has cancelled the keyhole and the key of conventional door lock by the motion that remote controller comes control gate Lock with inside lock tongue, can prevent that other unlocking tools from unblanking by keyhole, play good antitheft effect.

The specific embodiment
As shown in Figure 1, a kind of theftproof lock, comprise lock box 1, control circuit box 2 and remote controller 3, the dead bolt 4 of locking effect has been housed in the lock box 1, motor 5 also is housed in the lock box 1, motor 5 is fixed on the dead bolt 4, the motion of dead bolt 4 is driven by motor 5, the output of motor 5 is equipped with gear, is fixed with tooth bar 6 in the lock box 1, and wheel and rack 6 is meshing with each other, motor 5 can drive dead bolt 4 motions when rotating, be electrically connected between motor 5 and the control circuit box 2, on the remote controller 3 wireless launcher be housed, on the control circuit box 2 wireless receiver is housed.The effect of remote controller 3 is key, and open and close lock button is set on it, and remote controller 3 is controlled the rotating of motor 5 by control circuit box 2, thereby controls stretching out and withdrawal of dead bolt 4.Wireless launcher on the remote controller 3 adopts the electronic code transmitter, and it is corresponding with Lineside encoding unit that decoder is set on the control circuit box 2, like this, just makes door lock not have traditional keyhole and key, had better anti-theft effect.
As shown in Figure 1, on the circuit between motor 5 and the control circuit box 2 magnetic switch 7 is set, magnetic switch 7 is a normally open, the closed circuit of connecting when magnetic switch 7 is subjected to magneticaction.This magnetic switch 7 can be installed in the shelter, before unblanking, with magnetic bodies or ferrous material near magnetic switch, can be with the magnetic switch closure of often opening, thus connect circuit.Like this, can play further raising anti-theft effect.
Shown in Fig. 1,4, oblique tongue 8 also is housed on the lock box 1, tiltedly tongue 8 is provided with the shifting block 9 that stretches out lock box, and shifting block 9 is used for manually stirring oblique tongue 8, and this structure and common door are phase-locked together.
As shown in Figure 1, 2, 3, tiltedly be provided with link gear between tongue 8 and the dead bolt 4, when unblanking, the dead bolt withdrawal can drive oblique tongue withdrawal.This link gear is a push rod of stirring oblique tongue 8 10 that is arranged on the dead bolt 4, this push rod 10 can move along its axis, push rod 10 is provided with inclined-plane 11, and the lock box 1 at close dead bolt 4 rear portions is provided with jacking block 12, and this jacking block 12 faces the inclined-plane 11 of push rod.When dead bolt 4 withdrawals, when jacking block 12 was run on the inclined-plane 11 of the push rod on the dead bolt, push rod 12 moved axially along self, just can discharge oblique tongue 8.In the push rod back-moving spring 13 can be set, make push rod 10 be in the position that to stir oblique tongue 8.Set the relative position of jacking block 12 and push rod 10, make when unblanking, dead bolt 4 can be withdrawn into lock box 1 simultaneously with oblique tongue 8, so that open the door.As people at home the time, can only use oblique tongue 8 to close the door dead bolt 4 withdrawals, use a teleswitch the open and close door thereby saved, just more convenient.
