Description

The rolling-gate anti-theft device

(1) technical field.The utility model relates to a kind of rolling-gate anti-theft device, is loaded on the building rolling-gate.

(2) background technology.At present, the pin card of employed rolling-gate generally is tiny flat steel bar or the circle bar that inserts the doorframe chute, and is extremely insecure, very easy being pried open, and safety, theftproof are relatively poor.Do not find as yet with the anti-theft device that this device is similar.

(3) summary of the invention.

Technical problem to be solved in the utility model is: design a kind of rolling-gate anti-theft device, to improve the theftproof of rolling-gate.

The technical scheme that the utility model addresses the above problem is: its support vertically is installed on the spout, lockpin sleeve vertically is loaded on the support, lock pin is loaded in the lockpin sleeve, be equiped with return spring on the lock pin, design has pintle hook lock piece and a triangle iron block that cooperates with lock pin, and designing has the drive block that cooperates with the buzzing contact head installed on the spout.Design has the hole and the installing hole of pin bushing, oblong aperture, installation buzzing contact head on the base plate of spout, two wallboards have been welded, form groove between the wallboard, be equiped with cross locking bar bayonet lock between two wallboards, design has the arc notch that matches with the locking cone head of lock pin on a wallboard.Design has pane and pin bushing, the pane of support to be plugged in the oblong aperture on the spout base plate on the support, and inserts in the pin bushing by latch and to adorn connection.

The beneficial effects of the utility model.Owing to the utlity model has the said structure design, during installation, need not to change in a large number the rolling-gate structure, only need rolling-gate left and right sides doorframe chute bottommost is sliced off suitable with the spout size one section (newly install rolling-gate only need reserve the relevant position get final product), on the wall of this position, load onto spout then, and its groove is alignd with the doorframe chute of rolling-gate, on the following relevant position of rolling-gate door leaf perpendicular to the covering of the fan triangle iron block that has been welded, and be contained in pintle hook lock piece and drive block on the cross locking bar of rolling gate door lock with different angles, make the pintle hook lock piece, the triangle iron block cooperates appropriately with the lock pin head, and drive block cooperates appropriately with the buzzing contact head and gets final product.When locking rolling-gate, the lock pin head of this device is blocked by the pintle hook lock piece, even when having the people upwards to force open the door, the pintle hook lock piece blocks the lock pin head all the time, and orders about the buzzing contact head and connect buzzer, reports to the police.Thereby fixing, the theftproof of rolling-gate have been improved greatly.In the time will opening rolling-gate, only need with key turn rolling-gate door lock, the cross locking bar of its lock inwardly contracts and moves, when upwards mentioning the rolling-gate door leaf, pintle hook lock piece and drive block break away from lock pin head and buzzing contact head respectively, and lock pin is out of control, triangle iron block inclined-plane pushing lock pin head, the return spring compression, lock pin retreats, thereby opens rolling-gate.At closing time, carry out and above-mentioned opposite moving, return, the pintle hook lock piece blocks the lock pin head, the theftproof performance of reinforced door.
