Abstract
The utility model provides an anti-theft device for alarm, which comprises an alarm bottom cover and an alarm base, and is characterized in that: the edge of the alarm bottom cover is provided with two heaves, and a security groove is arranged at an appropriate position; two L-shaped slots are arranged on an fringe wall of the alarm base, and the positions of the L-shaped slots are corresponding to the two heaves on the alarm bottom cover; an anti-theft card is positioned at the fringe wall; the processing structures for the anti-theft card can be in an A-part circular arc structure, a B-part circular heave structure and a C-part groove structure; the position of the anti-theft card is corresponding to the security groove on the alarm bottom cover; an opening slot is positioned nearby the anti-theft card; the position of the opening slot relatives to the C-part groove structure of the anti-theft card, and the alarm bottom cover is tightly matched with the alarm base through the match between the L-shaped slots and the heaves. The anti-theft purpose can be reached by matching the B-part circular heave of the anti-theft card with the security groove.
Description
Technical field
The utility model relates to a kind of anti-theft device, especially a kind of anti-theft device that is used for alarm.
Background technology
The connected mode of the stationary installation of existing fire protection warning device generally is: the groove that twice L type is arranged on alarm base edge wall, at alarm bottom edge two small embossments are arranged, the vertical slot of two on alarm bottom projectioies being aimed at L type groove on the alarm base edge wall during installation inserts, rotating to an angle by the translot direction of L type groove screws in the bossing on the alarm bottom edge in the translot of L type groove again, thereby alarm is fixed on the alarm base.This coupling arrangement can retrograde rotation, and therefore, anyone can any instrument and alarm is taken off from base steal like a cork.
The purpose of this utility model is a kind of anti-theft device that overcomes above shortcoming of development.
The utility model is by alarm bottom (1), alarm base (2) is formed, wherein, be processed with two projectioies (3) on the edge of alarm bottom (1), in position process an antitheft groove (4), be processed with two L type grooves (5) on the edge wall of alarm base (2), the position of L type groove (5) is corresponding with two projectioies (3) on the alarm bottom (1), and on edge wall, process an antitheft card (6), the structure of antitheft card (6) has been processed into A portion arc structure, B portion bulge-structure, C portion groove structure, the position of antitheft card (6) is corresponding with antitheft groove (4) on the alarm bottom (1), process an opening groove (7) on the next door of antitheft card (6), the position of opening groove (7) is corresponding with the C portion groove structure of antitheft card (6), and alarm bottom (1) cooperates to reach with alarm base (2) and closely cooperates with projection (3) by L type groove (5).The B portion bulge-structure of antitheft card (6) cooperates with antitheft groove (4) and reaches antitheft purpose.Opening groove (7) is realized light pickup.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Figure one is the structural representation of the utility model embodiment 1.
Figure two is structural representations of the utility model embodiment 2.
Figure three is structural representations of the utility model embodiment 3.
Figure four is structural representations of the utility model embodiment 4.
Figure five is sectional views of alarm base of the present utility model.
1 alarm bottom, 2 alarm bases, 3 projectioies, 4 antitheft grooves, 5L type groove, 6 antitheft cards, 7 opening grooves among the figure
In the drawings, alarm bottom (1) cooperates to reach with alarm base (2) and closely cooperates with projection (3) by L type groove (5).The B portion bulge-structure of antitheft card (6) cooperates with antitheft groove (4) and reaches antitheft purpose.Opening groove (7) is realized light pickup.
Embodiment
The vertical slot that the projection (3) of alarm bottom of the present utility model (1) is aimed at L type groove (5) inserts, horizontally rotate the translot end of L type groove (5), at this moment, the B portion bulge-structure of antitheft card (6) just in time embeds in the antitheft groove (4) on the alarm bottom (1), because it is the right angle that B portion bulge-structure has a limit, so alarm can't retrograde rotation, thereby can't take out, reach antitheft purpose, the A portion arc structure of antitheft card (6) is keeping at ordinary times, before formal the installation, just it is cut with nose pliers, at this moment, burglar-proof mechanism just is in operating state, if do not cut the A portion arc structure of antitheft card (6), the B portion bulge-structure of antitheft card (6) is because length is not enough, can't embed in the antitheft groove (4), therefore alarm can rotate freely, convenient debugging, after formal the installation, when needs take out maintenance with alarm, can insert from opening groove (7) with a tip of a root head spillikin shape instrument, and just in time insert in the C portion groove structure of antitheft card (6), antitheft card (6) is levered up, the B portion bulge-structure of antitheft card (6) is spun off from antitheft groove (4), this moment, alarm can be taken out by retrograde rotation.
That anti-theft device of the present utility model has is easy and simple to handle, good anti-theft effect, durable in use etc. Advantage.
Claims (5)
