Description

Door lock anti-theft alarm structure

Technical field

The invention relates to a door lock anti-theft alarm structure, belonging to the technical field of locks.

Background technique

The usual door locks do not have anti-theft alarm function. The optimization of the door lock is mainly focused on increasing the anti-theft performance of the door lock, especially the electronic door lock. Although its continuous intelligence improves its reliability, the anti-theft performance is still electronic. A drawback of the door lock. For example, Chinese Patent Application No. 201220194699.6 discloses an electronic anti-theft door lock, wherein a semi-annular locking tongue is respectively hinged on the upper and lower sides of the lock body, and a semi-annular locking tongue is inserted and passed through on the side wall of the lock body. a through hole, a center of the semi-annular locking tongue is fixed with a gear, and the upper locking rod and the lower locking rod are provided with a rack, and the rack is meshed with the gear on the corresponding semi-annular locking tongue, and the fingerprint electronic anti-theft lock is Based on the prior art, two boxes of semi-annular locking tongues are added, which effectively improves the anti-theft performance; although the anti-theft performance is enhanced by the improvement of the structure, if the door is inserted into the room, no matter how good the door lock is, it is useless. People began to develop various anti-theft alarm devices. Chinese Patent Application No. 99254048.8 discloses a dual electronic lock anti-theft alarm lock, which comprises a power electronic lock and an alarm electronic lock respectively provided with a contact switch and a slide switch, and an electronic lock control circuit connected with the double electronic lock. The audible alarm control circuit, the motor and the drive control circuit thereof respectively connected to the electronic lock control circuit further comprise a lock tongue connected to the motor and a lock tongue drive structure thereof and an alarm self-locking circuit linked with the influence alarm control circuit, two electronic The locks are controlled by each other. Only when the two keys are screwed in one direction at the same time and simultaneously, the motor can be driven to rotate in one direction, and the lock tongue is controlled to move in one direction, and the lock is opened and closed; although the door lock has an alarm function. Compared with other door locks, the safety performance is greatly increased, but the operation method is easy to cause misoperation and false alarm, and the feasibility is not large. In addition, the continuous development of updated networked door locks, which is more focused on the intelligentization of the door lock network, needs to be improved in terms of security.

Summary of the invention

The object of the present invention is to overcome the above drawbacks and provide a door lock anti-theft alarm structure with simple structure, ingenious design and high intelligence degree, which is preferably applied to a networked door lock, and can achieve an ideal anti-theft without adding complicated alarm equipment. The alarm function is low in cost and suitable for promotion on the door lock.

In order to achieve the above object, the technical solution of the present invention is as follows:

A door lock burglar alarm structure includes a lock case, a screw, a micro switch and a circuit board, wherein the lock case is provided with a through hole through which the screw is fixed to the lock case; The movable switch is disposed vertically away from the through hole Position, the tail of the screw contacts the micro switch and the swing lever is in a pressed state, and the micro switch is connected to a circuit board disposed in the lock case, and the circuit board includes a communication module. The advantage is that when the door lock is in the normal use state, the screw presses the swing lever of the micro switch, and the micro switch and the circuit board are in an on state, and when the door lock is opened, the screw is Remove, at this time, the swing lever of the micro switch pops open under the action of its own elastic force, the micro switch is disconnected from the circuit board, and the circuit board immediately sends an alarm signal after receiving the disconnection signal, and the communication module also This signal will be uploaded to the server terminal.

Further, the micro switch is fixed to the inside of the lock case by screws.

Further, the through hole is disposed at the bottom of the lock case. The advantage is that it has a certain concealment, and to some extent prevents artificially disassembling the door lock.

The invention has the advantages that the device of the invention has a simple structure, and if a person wants to enter the room maliciously, the door lock is generally broken by using a special tool mechanical means, and the damage of the door lock must cause the screw to fall off or shift. When the micro switch is disconnected from the circuit board, the board receives this signal, and the corresponding module will immediately send an alarm signal, so the alarm accuracy is extremely high.

detailed description

The specific embodiments of the present invention are described below in conjunction with the drawings in order to provide a better understanding of the invention.

The door lock anti-theft alarm structure shown in FIG. 1 includes a lock case 1, a screw 2, a micro switch 3 and a circuit board, and the lock case 1 is provided with a through hole 5 through which the screw 2 passes. The sliding cover 6 is fixed on the lock case 1 as shown in FIG. 3 and FIG. 4; the micro switch 3 is disposed at a position vertically away from the through hole 5, and the tail portion of the screw 2 is in contact with the micro switch 3 and The swinging rod 4 is in a pressed state. As shown in FIG. 2, the micro switch 3 is connected to the circuit board through a line, and the circuit board includes a communication module. The advantage is that when the door lock is in normal use, the screw 2 is pressed The swing lever 4 of the micro switch 3 is connected, and the micro switch 3 and the circuit board are in an ON state. When the door lock is opened, the screw 2 is removed, and the swing lever of the micro switch 3 is at this time. 4 Bounced under the action of its own elastic force, the micro switch 3 is disconnected from the circuit board, and the circuit board will immediately send an alarm signal after receiving this signal, and the communication module will also upload this signal to the server terminal.

The micro switch 2 is fixed to the inside of the lock case 1 by screws 2. As shown in FIG. 3 and FIG. 4, the through hole 5 is disposed at the bottom of the lock case 1 and has a certain concealing property. To some extent, an artificially disassembled door lock is artificially placed.

The door lock anti-theft alarm structure according to the present invention has a simple structure, and if a person wants to enter the room maliciously, the door lock is generally broken by using a special tool mechanical means, and the destruction of the second door lock must cause the screw 2 to fall off or shift. At this time, the micro switch 3 is disconnected from the circuit board, and the circuit board receives this signal, and the corresponding module will immediately issue an alarm signal, so the alarm accuracy is extremely high.

The above is a preferred embodiment of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. It is the scope of protection of the present invention.
