Shape, there is an urgent need to develop a kind of distribution box anti-theft alarm systems, to overcome the shortcomings of in currently practical application.
Utility model content
The purpose of this utility model is to provide a kind of distribution box anti-theft alarm systems, improve the deficiencies in the prior art,
Can reduce distribution box inner air switch stolen risk and it is stolen when sound an alarm, it is practical.
The embodiments of the present invention are achieved in that
A kind of distribution box anti-theft alarm system, comprising: cabinet, cabinet door and air switch, the air switch surface are equipped with
Shield, the shield surface are equipped with opening, and described shield one end is welded with convex block, and the convex block and tank surface are all provided with
There is bolt hole, is equipped with elastic piece inside the tank surface bolt hole, the elastic piece surface and bolt hole inner wall are equipped with touching
Point, the elastic piece surface run through loose slot, run through inside the loose slot and be equipped with hold-down bars, and the hold-down bars surface is equipped with multiple
Position spring.
Preferably, the shield left end is connected through hinge activity with cabinet, and is between hinge, shield and cabinet
Welding.
Preferably, the shield opening width is less than shield width, and is open and is located at shield center.
Preferably, the elastic piece is steel disc, and the contact and elastic piece on bolt hole inner wall pass through conducting wire and extraneous power supply
It is electrically connected with alarm.
Preferably, the reset spring is set to elastic piece lower surface, and loose slot is ellipse.
The utility model has the advantages that
1, by setting shield, opening and convex block, bolt is inserted into bolt hole and shield is fixed on sky the utility model
The fixing bolt on air switch is blocked in air cock surface, shield upper surface, and air switch handle is embedded in opening, In
The normal use of air switch is not influenced while playing protection and anti-theft function to air switch.
2, the utility model has the advantage of by bolt hole be arranged elastic piece, contact, when air switch is stolen,
Play the role of exciting alarm, by the way that reset spring is arranged in elastic piece lower end, can be avoided since elastic piece deformation causes
Contact the case where can not touching.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment:
Please refer to Fig. 1 to 4, in the utility model embodiment, a kind of distribution box anti-theft alarm system, comprising: cabinet 1, cabinet
Door 2 and air switch 3,3 surface of air switch are equipped with shield 4, and 4 surface of shield is equipped with opening 5, the welding of 4 one end of shield
There is convex block 6, convex block 6 and 1 surface of cabinet are equipped with bolt hole 7, are equipped with elastic piece 8, elastic piece 8 inside 1 surface bolt hole 7 of cabinet
Surface and 7 inner wall of bolt hole are equipped with contact 9, and loose slot 10 is run through on 8 surface of elastic piece, run through to be equipped with inside loose slot 10 and fix
Stick 11,11 surface of hold-down bars are equipped with reset spring 12.
Wherein, 4 left end of shield is connected through hinge activity with cabinet 1, and is weldering between hinge, shield 4 and cabinet 1
It connects, when air switch 3 is needed replacing or repaired, 4 side rotating opening of shield can be repaired.
Wherein, shield 4 is open 5 width less than 4 width of shield, and is open 5 positioned at 4 center of shield, protection
Cover 4 can block the fixing bolt of air switch 3, avoid air switch 3 stolen, meanwhile, usually in use, not needing to prevent
Shield 4 is opened can normal use air switch 3.
Wherein, elastic piece 8 is steel disc, the contact 9 and elastic piece 8 on 7 inner wall of bolt hole by conducting wire and extraneous power supply and
Alarm is electrically connected, and when bolt is inserted into bolt hole 7, withstands elastic piece 8, is made in contact 9 and the bolt hole 7 on 8 surface of elastic piece
The contact separation of wall, when someone loosers a bolt, with the rising of bolt, two contacts 9 are contacted, and alarm is alarmed.
Wherein, reset spring 12 is set to 8 lower surface of elastic piece, and loose slot 10 is ellipse, can avoid touching on elastic piece 8
9 poor contact of contact of point and 7 inner wall of bolt hole, influences alarm work.
Working principle, firstly, by inside mounted 1 bolt hole 7 of distribution box body contact 9 and elastic piece 8 by leading
Line and extraneous alarm and power supply are electrically connected, and then, with the bolt hole 7 on bolt insertion 4 convex block 6 of protecting crust, tighten bolt
It is bent elastic piece 8, two contacts 9 separate, at this time alarm no power, and protecting crust 4 has protection and antitheft to air switch 3
Effect, when distribution box is stolen, needs to unscrew the bolt on convex block 6, and when bolt is unscrewed, elastic piece 8 is acted in natural resiliency
Under the elastic force of spring 12,9 one end of contact is popped up, and touches two contacts 9, excites alarm, this distribution box excitation report
Alert device structure is not easy to be found than more covert.
