Abstract
The invention relates to an anti-theft alarm structure for a door lock. The anti-theft alarm structure comprises a lock casing, a screw, a microswitch and a circuit board, wherein a through hole is formed in the lock casing, the screw penetrates through the through hole to fix a sliding cover onto the lock casing, the microswitch is arranged at the position perpendicularly far away from the through hole, the tail of the screw is in contact with the microswitch to enable an oscillating bar of the microswitch to be in a pressing state, and the microswitch is connected with the circuit board comprising a communication module through a line. The anti-theft alarm structure for the door lock is simple in structure. When someone enters a room maliciously, special tools are utilized to destroy the door lock through mechanical means, then, falling or skewing of the screw is caused by destroying of the door lock, therefore, the microswitch is disconnected with the circuit board, and when the circuit board receives the signal, a corresponding module sends out an alarm signal immediately. Accordingly, the anti-theft alarm structure for the door lock is high in alarm accuracy.
Description
Technical field
The present invention relates to a kind of door lock anti-theft alarm structure, belong to lock technology field.
Background technology
Common door lock does not possess anti-theft alarm function, also mainly concentrate on the theftproof performance that increases door lock for the optimization of door lock, particularly electronic lock, although its continuous intellectuality has improved its reliability, a drawback of theftproof performance or electronic lock.The Chinese patent application that for example application number is 201220194699.6 discloses a kind of electronic anti-theft door lock, the both sides up and down of its lock body are hinged with respectively semi-circular dead bolt, the sidewall of lock body is provided with the through hole that semi-circular dead bolt penetrates and passes, the center of semi-circular dead bolt is fixed with gear, on upper locking bar and lower locking bar, be equipped with tooth bar, tooth bar is mutually meshing with the gear on corresponding semi-circular dead bolt, this fingerprint electron theftproof lock has increased by two box semi-circular dead bolts on the basis of existing technology, has effectively improved its theftproof performance; Although its improvement by structure has strengthened theftproof, enter the room if forced open the door, more also use not of good door lock, so people start to continually develop various burglar alarms.Application number is that 99254048.8 Chinese patent application discloses a kind of burglar alarm device for double electronic lock, it comprises the power supply electronic lock and the alarming electronic lock that are respectively equipped with contact switch and slide switch, lock with bielectron the electronic lock control circuit being connected, the audible alarm control circuit connecting respectively at electronic lock control circuit, motor and Drive and Control Circuit thereof, also include the dead bolt that is connected with motor and deadboft actuation structure thereof and with the warning latching circuit that affects alarm control circuit and link, two electronic locks restrict control mutually, only have while also synchronously turning two keys to a direction simultaneously, ability CD-ROM drive motor is towards a direction rotation, and control dead bolt and move to a direction, open, shut, although this class door lock has increased warning function, greatly increase security performance compared with other door locks, its method of operating is easy to cause maloperation, false alarm, and feasible degree is little.In addition, the networking door lock that development upgrades, what itself more focus on is door lock network-enabled intelligent, aspect safety, has much room for improvement.
Summary of the invention
The object of the invention is to overcome above-mentioned defect, provide a kind of simple in structure, design the door lock anti-theft alarm structure that ingenious, intelligent degree is high, it is preferably applicable to the door lock of networking, do not need to increase complicated warning device and just can reach desirable anti-theft alarm function, with low cost, be suitable for promoting the use of on door lock.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of door lock anti-theft alarm structure, includes lock housing, screw, microswitch and circuit board, and described lock housing is provided with through hole, and screw is fixed on slip lid in lock housing through described through hole; Described microswitch is arranged at the position of perpendicular distal from through hole, and the afterbody of described screw contacts with microswitch and makes its fork in stitching state, and microswitch passes through connection with the circuit board being arranged in lock housing, and described circuit board comprises communication module.Advantage is: when door lock is under normal operating condition, the fork of described screw pressing microswitch, now microswitch and circuit board are in on-state, in the time that door lock is pried open, described screw can be removed, and now the fork of microswitch flicks under self elastic force effect, microswitch and circuit board disconnect, circuit board is receiving after this cut-off signal and can send immediately alarm signal, meanwhile, and the communication module terminal that also this signal can be uploaded onto the server.
Further, described microswitch is screwed and lock housing inside.
Further, described through hole is arranged at lock housing bottom.Its advantage is, has certain disguise, prevented that to a certain extent artificial opposite house is locked into the dismounting of row malice.
Beneficial effect of the present invention is: apparatus of the present invention are simple in structure, if and artificial malice want to enter room, generally all can be by using special tool(s) machinery means to destroy door lock, and the destruction of door lock is bound to cause coming off or being offset of screw, now microswitch and circuit board disconnect, circuit board receives this signal, and corresponding module just can send alarm signal immediately, so the warning degree of accuracy is high.
