Description

A kind of alarm of rolling-gate

[technical field]

The utility model relates to a kind of anti-theft device, especially relates to a kind of anti-theft device of rolling-gate.

[background technology]

Rolling-gate is extensive use now, has characteristics easy to use, but often hears that rolling-gate is pried open, and stolen property the thief rob everything, and causes very big loss to the masses.This explanation rolling-gate anti-theft capability is poor, can both pry open with simple tools, does not have warning function, does not more have the ability that remote phone is reported to the police.

[utility model content]

The purpose of this utility model is a kind of rolling-gate alarm with warning function and remote phone alert capability that provides for the deficiency that overcomes existing rolling-gate alert capability.

In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposal:

A kind of alarm of rolling-gate, comprise base support, bolt support, bolt, ground box hook, expansion bolt, hook, lock core box, lock core; It is characterized in that being provided with in the lock core box microswitch, bolt withstands the contact of microswitch, microswitch is connected with expelling plate and controls the break-make of expelling plate power supply, and the digital intelligent alarm receives the signal of expelling plate, and the digital intelligent alarm connects telephone network, alarm buzzer;

Aforesaid microswitch is normally closed microswitch.

Vertical fixing has the bolt support on the aforesaid base support, and bolt one end passes in the hole of bolt support, and the bolt other end is set in the lock core box; The middle part of ground hook is hinged on the hinge on the base support, and hook top, ground is provided with a chute, places the slide-bar that is located on the bolt in the chute, the bottom of ground hook be fixed on expansion bolt the ground box hook in the box cooperate; Also be provided with back-moving spring between bolt and the base support; Base support is provided with the contact thimble, and bolt is provided with and contacts the locating piece that thimble cooperates.

The utility model compared with prior art has following advantage:

1, the utility model can be reported to the police by alarm buzzer, and in time reminds people makes people avoid property loss;

2, digital intelligent alarm buzzer acknowledge(ment) signal is arranged again after, thereby can put through the mobile phone of setting or landline telephone is reported to the police, make the masses know that rolling-gate is destroyed, in time protect one's own property and do not suffer a loss;

3, simple in structure, the dependable performance of the utility model.

[specific embodiment]

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

The alarm of (seeing Fig. 1,2,4) a kind of rolling-gate, comprise base support 1, bolt support 2, bolt 3, ground box hook 4, expansion bolt 5, hook 6, lock core box 7, lock core 8; Be provided with microswitch K in the lock core box, bolt 3 withstands the contact of microswitch K, microswitch is connected with expelling plate 9 and controls the break-make of expelling plate power supply, and digital intelligent alarm 15 receives the signal of expelling plates, and digital intelligent alarm 15 connects telephone networks, alarm buzzer 17.

Microswitch is normally closed microswitch.

When rolling-gate was in closed condition, bolt withstood microswitch K, made normally closed microswitch K dependence external force effect and was in off-state, and the expelling plate non-transformer is not worked.Force open the door or turn the key in the lock in case the robber is taken place, make bolt no longer withstand microswitch, microswitch recovers normally off, and expelling plate is connected power work, output alarm signal.

The circuit of expelling plate 9 comprises power circuit 9A and radiating circuit 9B; (seeing Fig. 2,3) power circuit is adjusted into external power supply the working power of radiating circuit; The core of radiating circuit is integrated IC1 of digital coding, and the model of IC1 is PT2262; IC1 gets electric work when microswitch K connects, by the 17 pin output high level coding alarm signal of ic chip 1, by resistance R 6, triode Q5, Q6, capacitor C 4 modulation, send signal by antenna L again; IC1 cuts off the power supply when microswitch K disconnects, 17 pin output low levels of ic chip 1, and signal is no longer sent in the radiating circuit failure of oscillations.SAW is a resonator.

(seeing Fig. 2,4-7) digital intelligent alarm 15 connects the input of telephone network, alarm buzzer 17, and digital intelligent alarm 15 receives the signal of expelling plate, can give landline telephone or the handset dialing that has set in the alarm after the processing, reminds the user; Also can report to the police by near the alarm buzzer of drive installation rolling-gate near people reminding and deterrence robber; Digital intelligent alarm 15 can also be provided with remote controller 20, is used for removing warning or carries out other operational orders.

Vertical fixing has bolt support 2 on the base support 1, and bolt 3 one ends pass in the hole of bolt support 2, and the bolt other end is set in the lock core box 7; The middle part of ground hook 6 is hinged on the hinge 10 on the base support 1, and hook top, ground is provided with a chute 11, places the slide-bar 12 that is located on the bolt in the chute, the bottom of ground hook be fixed on expansion bolt 5 the ground box hook 4 in the box cooperate; Also be provided with back-moving spring 13 between bolt and the base support.Base support 1 is provided with contact thimble 14, and bolt 3 is provided with and contacts the locating piece 140 that thimble cooperates.

The rolling-gate of leaving behind, when the base support kiss the earth, the contact thimble blocks locating piece on its right when door opening state, at this moment contact thimble touching ground, the contact thimble no longer blocks locating piece, and bolt stretches out toward and arranged on left and right sides under the tension of back-moving spring, when bolt stretches out, slide-bar on the bolt drives the ground hook and rotates around hinge, and the ground hook hooks ground box hook, finishes the process of closing the door; Again with the remote controller unlatching warning function of deploying troops on garrison duty.At this moment, if not lawless person's method is forced open the door or started lock core, the digital intelligent alarm all can be reported to the police.

When opening the door, turn off the digital intelligent alarm with remote-control key earlier; Start door lock with key, drive the ground hook when bolt shrinks, make the ground hook break away from ground box hook, can open the door around the hinge counter-rotation; At this moment, bolt is shunk to the centre by and arranged on left and right sides, and the contact thimble blocks locating piece, and simultaneously, the back-moving spring boil down to is closed the door ready.
