Abstract

The utility model relates to an anti-dismounting device of an alarm controller, for solving the problems of high cost and poor application effects of a conventional iron casing machine anti-dismounting device. The technical scheme of the solution is as follows: the anti-dismounting device comprises a plate body, a fixation body and conductive metal elastic sheets, wherein the fixation body is installed on the inner surface of the plate body through a screw; the fixation body is provided with a first conductive metal elastic sheet and a second conductive metal elastic sheet which are alternated; one end portion of the first conductive metal elastic sheet is provided with a conductive compressed tablet; the conductive compressed tablet is corresponding to one end of the second conductive metal elastic sheet; and the other corresponding ends of the first conductive metal elastic sheet and the second conductive metal elastic sheet are respectively provided with leads connected with an alarm. The anti-dismounting device of the alarm controller has the advantages of simple structure, easy production, low cost, convenient installation and use and good effects.

Description

The antiwithdrawal device of alarm controller

Technical field

The utility model relates to safety-security area, particularly a kind of antiwithdrawal device of alarm controller.

Background technology

Along with security product is constantly universal, market capacity constantly increases, and increasing manufacturer also joins security protection industry, and bring is also increasing market competition thereupon, especially also fiercer to the competition of product price, so each manufacturer is all at the cost that reduces by every means product.And in current security protection market, the iron shell machine of antitheft alarming controller, according to GB, require all will have antiwithdrawal device, and current iron shell machine antiwithdrawal device, cost is all higher, uses plastic cement structure, because of needs production mould, same cost is very high, and result of use is poor, is therefore difficult to apply.

Summary of the invention

For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of antiwithdrawal device of alarm controller, can effectively solve the current problem that iron shell machine antiwithdrawal device cost is high and result of use is poor.

The technical solution of the utility model is, comprise plate body, fixed body and conducting metal shell fragment, fixed body is contained on plate body inner face through screw, the first alternate conducting metal shell fragment is housed on fixed body, the second conducting metal shell fragment, on one end of the first conducting metal shell fragment, conduction compressing tablet is housed, conduction compressing tablet is corresponding with one end of the second conducting metal shell fragment, on the corresponding other end of the first conducting metal shell fragment, the second conducting metal shell fragment, the wire being connected with alarm is housed respectively.

The utility model is simple in structure, easily produces, and cost is low, easy to install, effective.

Accompanying drawing explanation

Fig. 1 is the structural front view of two shell fragments of the present utility model while opening.

Structural front view when Fig. 2 is two shell fragments closure of the present utility model.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.

By Fig. 1 Fig. 2, provided, the utility model comprises plate body, fixed body and conducting metal shell fragment, fixed body 4 is contained on plate body 7 inner faces through screw 6, the first alternate conducting metal shell fragment 1 is housed on fixed body, the second conducting metal shell fragment 2, conduction compressing tablet 3 is housed on one end of the first conducting metal shell fragment, conduction compressing tablet is corresponding with one end of the second conducting metal shell fragment, on the corresponding other end of the first conducting metal shell fragment, the second conducting metal shell fragment, wire 5a, the 5b being connected with alarm is housed respectively.

In order to guarantee result of use, described plate body be insulating material make square or circular; The first described conducting metal shell fragment, the second conducting metal shell fragment are identical square of length that the copper of same structure becomes; Described conduction compressing tablet is the Elastic Circular sheet that copper or alloy are made.

When the utility model is used, plate body is fixed on the sidewall below of alarm lid, alarm lid is pressed on the second conducting metal shell fragment conducting electricity compressing tablet on the first conductive metal sheet, and

wire

5a, 5b are connected with alarm gauge tap, when alarm lid closes while closing, conduction compressing tablet is pressed on another conducting metal shell fragment and forms alarm short-circuit, alarm is not reported to the police, and when opening while covering, conduction compressing tablet and another conductive metal sheet are separated, form alarm path, alarm equipment alarm.

As can be seen from the above, the antitheft alarming controller that is iron-clad for shell, its antiwithdrawal device is generally installed on iron-clad inwall, and when face-piece is closed, face-piece inwall is pressing breaking-proof switch, two shell fragments of breaking-proof switch are contacted tightly, and two shell fragments of breaking-proof switch are followed respectively a wire, receive respectively on wired defence area connection terminal of burglar alarm main frame one end in addition, thereby having formed a closed loop, is that alarm is not reported to the police for normal condition in this state; When opening face-piece (lid), the breaking-proof switch that face-piece inwall is pressing, separates two shell fragments of breaking-proof switch because external force disappears, and the state that originally forms a closed-loop path has been changed, and alarm gives the alarm in this state;

When the utility model is implemented in concrete installation, also can save plate body, directly insulation fixed body is fixed in iron-clad wall with joint cement, location distance from face-piece inwall very close to, follow respectively in addition a wire, receive respectively on wired defence area connection terminal of burglar alarm main frame one end in addition, makes when face-piece is closed, two shell fragments can be oppressed together, thereby form a closed loop; When face-piece is opened, two shell fragment separation, closed loop is disconnected, thereby produce, reports to the police, and very easy to use flexible, tamper is effective, is the innovation on security device, has good economic and social benefit.
