CN205637953U - Alarm device is prevented tearing open by electron climbers - Google Patents

Abstract

The utility model discloses an alarm device is prevented tearing open by electron climbers, the electron climbers include circuit board, spring bolt and hasp, the strong magnet is installed to the spring bolt below, the magnetic force switch is installed to the hasp below, the magnetic force switch be connected with the circuit board. The hasp below is equipped with the protection cavity, the magnetic force switch mounting is in the protection cavity. The circuit board is installed in circuit case. The utility model discloses prevent at the whole in -process of going out to escort that climbers from being opened, normal during operation, the strong magnet is close to the magnetic force switch, and the switch closure does not produce the warning, after climbers are opened, go up and then can produce the warning after the strong magnet breaks away from the magnetic force switch of opening in the protection cavity. Guarantee the controllable and safety of the whole process of escorting.

Description

An electronic foot buckle tamper-proof alarm device

technical field

The utility model relates to the field of structure anti-dismantlement, in particular to an electronic foot buckle anti-dismantlement alarm device.

Background technique

The functional management and control system is used on the outbound escort device, which can not only locate the user in real time, but also perform positioning when an escape occurs. If it is not managed and controlled during the entire use process, it will not be able to achieve the role of supervision. Anti-demolition is the management and control One of the means is that according to the regulations, under no circumstances anyone (including the police) can open the electronic foot buckle at will when going out for escort, so it is necessary to design an electronic foot buckle anti-demolition alarm device to control this situation.

Contents of the invention

Aiming at the problems existing in the prior art, the utility model provides an electronic foot buckle anti-disassembly alarm device which prevents the foot buckle from being opened during the whole process of going out to escort, and ensures the controllability and safety of the whole escort process.

The purpose of this utility model is achieved through the following technical solutions.

An electronic foot buckle anti-demolition alarm device, the electronic foot buckle includes a circuit board, a lock tongue and a lock buckle, a strong magnet is installed under the lock tongue, a magnetic switch is installed under the lock buckle, and the magnetic switch Connect to the circuit board.

Further, a protective cavity is provided under the lock, and the magnetic switch is installed in the protective cavity.

Further, the circuit board is installed in the circuit box.

Compared with the prior art, the utility model has the advantages that: the utility model prevents the foot buckle from being opened during the whole process of going out for escort. After being opened, an alarm will be generated after the upper strong magnet is separated from the magnetic switch in the protection cavity. Ensure the controllability and safety of the entire escort process.

detailed description

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in FIG. 1 , an electronic foot buckle tamper-proof alarm device, the electronic foot buckle includes a circuit board 1 , a lock tongue and a lock buckle, and the circuit board 1 is installed in a circuit box.

As shown in FIG. 2 , a strong magnet 3 is installed in the wall of the buckle under the lock tongue, and a magnetic switch 4 is installed under the lock tongue, and the magnetic switch 4 is connected to the circuit board 1 . A protection cavity 2 is provided below the lock, and the magnetic switch 4 is installed in the protection cavity 2 . In the closed state of the deadbolt, the strong magnet 3 is protected in the wall body of the foot buckle and the protection cavity 2 .

When working normally, the strong magnet 3 installed on the wall of the foot buckle is close to the magnetic switch 4, the switch is closed, and no alarm is generated; when the foot buckle is opened, the strong magnet 3 installed on the wall of the foot buckle is separated from the protection cavity 2 After the magnetic switch 4 in the alarm will be generated.

The ankle strap is on the ankle, and the protection cavity 2 is between the lock buckle and the ankle, and the protection cavity 2 is partly protected in the circuit box.
