Abstract
The utility model discloses a pick-proof switch of the protective netting, comprising a insulating pedestal, a fixed contacting piece, a dynamic contact striking flake and an insulating cover, wherein the insulating pedestal is equipped with a projection, the fixed contacting piece is arranged on the right side of the projection and bends along the surface of the projection, the dynamic contact striking flake is disposed on the left side of the projection and fixed on the surface of the projection, the fixed contacting piece and the dynamic contact striking flake constitute a contact on the top of the projection, and the insulating cover is covered on the projection and cooperates with the projection. When the pick-proof switch of the protective netting is utilized, the pedestal is fixed on the main path of the aluminum alloy path of the hidden protective netting, the insulating cover is resisted against the path cover board, the fixed contacting piece and the dynamic contact striking flake are connected with an alarm, and the upper ends of the fixed contacting piece and the dynamic contact striking flake are electronically connected under the pushing of the insulating cover. When the aluminum alloy path is broken open artificially, the cover board loosens and the insulating cover loses the pushing of the cover board and loosens, the dynamic contact striking flake rebounds off the fixed contacting piece, and finally the power-off alarm alarms, thereby realizing the pick-proof purpose.
Description
Technical field
The utility model relates to a kind of pick-proof switch, relates in particular to a kind of protection network pick-proof switch.
Background technology
The stealth protection net that is made of steel wire rope and aluminium alloy track has entered people's balcony, window, and is very popular with its peculiar stealthy effect, and has protection and anti-theft feature simultaneously.The anti-theft feature of stealth protection net realizes by connect broken string or short-circuit alarming device at the steel wire rope two ends, opens circuit or during short circuit, alarm can be finished actuation of an alarm when protection network is caused by artificial destruction.But owing to the aluminium alloy track is connected with alarm, when the aluminium alloy track suffers artificial destruction, the antitheft effect that the stealth protection net just loses.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of protection network pick-proof switch that is installed in the stealth protection net aluminium alloy track to be provided.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind of protection network pick-proof switch, comprise insulator foot, fixed touching plate, movable contact shell fragment and insulating cover, insulator foot is provided with a projection, fixed touching plate is located at the right of projection and bends along lug surface, the movable contact shell fragment is located at the left side of projection and is fixed in lug surface, fixed touching plate and movable contact shell fragment constitute a contact at the item end of projection, and insulating cover is enclosed within on the projection and with projection and matches.
The described projection left side is provided with an inclined-plane, and movable contact shell fragment lower end is fixed on the base, and the upper end edge projection has stood tall and upright and has been bent to the fixed touching plate top along the inclined-plane, forms a contact with fixed touching plate.
The lower end of described fixed touching plate and movable contact shell fragment all by screw on base.
Be respectively equipped with through hole on the described base both ends of the surface.
Owing to adopted said structure, protection network pick-proof switch of the present utility model in use, base is fixed on the backbone of aluminium alloy track of stealth protection net, insulating cover props up the track cover plate, fixed touching plate is connected with alarm with the movable contact shell fragment, and the upper end of fixed touching plate and movable contact shell fragment being connected by depressing conduction insulating cover.When the aluminium alloy track by the people when prying open, cover plate unclamps, insulating cover unclamps when losing pushing of cover plate, movable contact shell fragment bullet is from fixed touching plate, power-off alarm is reported to the police, thereby realizes the purpose of pick-proof.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the part exploded view of Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figures 1 to 3, a kind of protection network pick-proof switch comprises insulator foot 1, fixed touching plate 5, movable contact shell fragment 3 and insulating cover 7, and 1 central authorities are provided with a projection at insulator foot, are respectively equipped with through hole 8,9 on the plate face of base the right and left.The projection left side is provided with an inclined-plane, and movable contact shell fragment 3 is located at the left side of projection, fixedlys connected with base 1 by screw 4 in the lower end, the bending of upper end edge lug surface.Fixed touching plate 5 is located at the right of projection, fixedlys connected with base 1 by screw 6 in the lower end, the bending of upper end edge lug surface.Fixed touching plate 5 tops 51 constitute a contact with the top 31 of movable contact shell fragment 3 at the item end of projection.Insulating cover 7 is enclosed within on the projection and with projection and matches.
Operation principle of the present utility model is as follows:
1, with the movable contact shell fragment with touch shell fragment surely and be fixed on the base, then base is fixed on the backbone of aluminium alloy track of stealth protection net, and movable contact spring with touch shell fragment surely and be connected with wire break alarm;
2, put insulating cover, cover the aluminium alloy cover plate then, the movable contact shell fragment is connected with the fixed touching plate conduction;
3, when aluminium alloy track during by artificial destruction, cover plate is loosening, and the movable contact spring bullet is from fixed touching plate, and circuit disconnects, alarm equipment alarm, thus realize the purpose that the pick-proof newspaper is stolen.
Claims (4)
1, a kind of protection network pick-proof switch, it is characterized in that: comprise insulator foot, fixed touching plate, movable contact shell fragment and insulating cover, insulator foot is provided with a projection, fixed touching plate is located at the right of projection and bends along lug surface, the movable contact shell fragment is located at the left side of projection and is fixed in lug surface, fixed touching plate and movable contact shell fragment constitute a contact at the item end of projection, and insulating cover is enclosed within on the projection and with projection and matches.
