Problems solved by technology

[0004] But the anti-theft alarm door plug of the above-mentioned structure still has an obvious technical defect, and this technical defect is exactly that the anti-theft alarm door plug of the above-mentioned structure is inserted in the door gap when in use, and can only prevent outsiders from forcibly opening the door and entering the room. When the distance between the door body and the ground is relatively large, when an outsider pushes the door stopper of the above structure out of the door gap with bare hands or with their own tools, the outsider then opens the door, and the door stopper Just can't be subjected to the exerted pressure of door, promptly the door stopper of above-mentioned structure has also just lost the function of original alarm reminder

Abstract

The invention discloses a door stopper alarm apparatus. The door stopper alarm apparatus comprises a base body with a wedge face on the top, an elastic pressing plate is arranged above the wedge face of the base body, the end of one side of the elastic pressing plate is inserted into the end of one side of the base body, the base body applies rotating torsion to the elastic pressing plate so as to ensure that an included angle is kept between the elastic pressing plate and the wedge face all the time, and an alarm device, a battery, a storage unit, a controller and a detection unit with a telescopic detection rod are arranged in the base body; a through hole is formed in the wedge face of the base body, a telescopic trigger connecting rod is arranged in the through hole in a penetrating manner, the trigger connecting rod ensures that the top of the connecting rod makes contact with the bottom face of the elastic pressing plate under the effect of a first reset spring, and the bottom end of the trigger connecting rod is arranged on the telescopic detection rod and makes contact with the telescopic detection rod; the detection unit converts displacement amount of the telescopic detection rod into an electric signal to be input to the controller, and when the detection unit detects that the elastic pressing plate has the displacement changes, the controller controls the alarm device to given an alarm; the technical aim of improving sensitivity of the alarm of the door stopper alarm apparatus is achieved, and the wide market application prospect is achieved.

Description

technical field [0001] The invention relates to an anti-theft alarm device, in particular to a door plug alarm. Background technique [0002] When the door is in the open or closed state, the traditional door stopper alarm can only achieve the purpose of stopping the door. But, along with the development of modern society, this single-function door stopper alarm can no longer satisfy people's needs in daily life, and people need a door stopper alarm with more functional effects. In particular, family theft often occurs in modern society, which poses a great threat to people's personal and property safety. [0003] In view of the above situation, the patent No. is 201520141484.1 and just provides a kind of anti-theft alarm door plug in the announced Chinese utility model patent document. Its structure includes an alarm horn for alarming, a power supply device for providing power to the alarm horn, a switch for controlling the alarm horn and a switch fixed to the elastic con...
