Abstract
The utility model relates to a portable antitheft cushion. The antitheft cushion is provided with a thin, light and rectangular hollow cushion body which can be placed in a computer bag or a handbag; a switch is arranged on the cushion body, and an automatic detection control circuit and an alarm device with an alarm HA are installed in the cushion body. In case of theft, once the cushion body is pressed, then the alarm HA can give an alarm; and the portable antitheft cushion has simple structure, can give an alarm in case of theft, stops the theft behavior and effectively protects the safety of property of people.
Description
Technical field
The utility model relates to a kind of mat with anti-theft feature, especially a kind of portable security alarm pad.
Background technology
In the public place of crowd's comparatively dense, as automobile, train or peak period on and off duty, article are easy to stolen, cause serious economy loss to the people, how can in time find stolen situation and call a halt, and are the problems that needs solve.
The utility model content
In order to solve the stolen problem of people's article, the utility model proposes a kind of portable security alarm pad, this antitheft mat structure is simple, can send the warning of reporting to the police in stolen, stops proceeding of pilferage behavior, has effectively protected the safety of people's properties.
The technical scheme that its technical matters that solves the utility model adopts is: this portable security alarm pad comprises pad, Automatic Detection and Control circuit and switch; This is antitheft to be lined with a hollow pad of frivolous rectangle that can be placed in computer package or the handbag; This pad is provided with switch, and the Automatic Detection and Control circuit is installed in the pad, the R in this Automatic Detection and Control circuit
