Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a low-voltage apparatus's anti-electricity-theft device, including

box

2 and 2 opening parts of box rotate the chamber door 1 of connecting, still include fixed lock 3 on the

chamber door

1, 3 inboard rotations of lock are connected with lock core 4, buckle 5 has been seted up to 4 one sides of lock core, and

buckle

5 and 2 opening parts joint of box, it is connected with swinging arms 6 to rotate through pivot 12 on the 3 bottom chamber door 1 of lock, plate electrode 11 has all been seted up to 6 both sides of swinging arms on the

chamber door

1, 11 outside electric connection of plate electrode have siren 10, and

siren

10 and 6 electric connection of swinging arms, so that put through siren 10 and begin to send out the police dispatch newspaper when swinging arms 6 and plate electrode 11 contact each other, wherein 10 built.

Specifically, as shown in fig. 2, the magnet 9 is disposed at the bottom end of the swing rod 6, the electromagnetic coil 7 is disposed on the inner side of the box door 1, and the central axis of the electromagnetic coil 7 and the central axis of the rotating shaft 12 are located on the same vertical plane, so that the magnet 9 does not swing when not being vibrated.

Specifically, as shown in fig. 3, a power supply device 8 is disposed at the bottom end of the electromagnetic coil 7, and the power supply device 8 is electrically connected to the electromagnetic coil 7, so that the electromagnetic coil 7 generates a magnetic field repulsive to the magnet 9.

Specifically, as shown in fig. 2, the outer surface wall of the latch 5 and the top end profile of the swing lever 6 are mutually attached, so that after the lock cylinder 4 is twisted, the latch 5 and the swing lever 6 are mutually attached and rubbed, and the swing lever 6 stops swinging.

Specifically, as shown in fig. 3, the central section of the rotating shaft 12 is in an "H" shape, and the swing lever 6 and the magnet 9 are both conductors, so that the deviation generated by the rotation of the swing lever 6 and the rotating shaft 12 is reduced.

Specifically, as shown in fig. 2, the magnetic poles of the electromagnetic coil 7 and the magnet 9 are in the same direction, so that the electromagnetic coil 7 and the magnet 9 repel each other until the magnet 9 and the electrode plate 11 contact each other and are energized.

The working principle is as follows: when the alarm is used, firstly, the rotating shaft 12 is connected with the swinging rod 6 in a rotating manner, so that the swinging rod 6 slightly swings when the box door 1 and the box body 2 are damaged by vibration or impact, then the swinging rod 6 is pushed by repulsive force to enhance the swinging when swinging through the electric connection between the electromagnetic coil 7 and the power supply device 8 and the same-direction magnetic poles between the magnet 9 and the electromagnetic coil 7 until the swinging rod 6 is contacted with the electrode plate 11, and at the moment, the circuit of the alarm 10 is switched on, so that the alarm 10 starts to alarm; secondly, when normally opening lock core 4, rotate lock core 4 and make buckle 5 and swing rod 6 top rub mutually, reduce swing of swing rod 6 to warning when avoiding normal use, when picking lock or illegally unblanking appearing, owing to need extra time to pick the lock, make the picking lock in-process can cause swing rod 6 to swing fast, and then lead to the work of siren 10, with the emergence of restriction picklock action.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
