Protective device with anti-theft function

Abstract

The invention provides a protective device with an anti-thief function, and relates to the technical field of alarm devices, the protective device comprises a base, a sponge windowsill is hinged to the front end of the base, the middle upper end of the sponge windowsill is of a sponge structure, the lower end of the sponge windowsill is of a solid structure, and guide columns are fixedly connected to the left side face and the right side face of the sponge windowsill; the sponge windowsill is slidably connected to the inner side of the base through the guide columns, and side plates are further fixedly connected to the left side face and the right side face of the base. The problems that when an existing alarm device carries out warning, sound and light are mostly adopted for reminding indoor personnel, mutual reminding of surrounding neighbors is lacked, and thieves cannot be effectively prevented from entering a room are solved, a support is synchronously unfolded through a steel cable installed on one side of a hook B, so that the safety of the thieves is improved, and the safety of the thieves is improved. After the support is separated from the pressing block arranged on one side of the stand column, thieves can be repelled through continuous flickering of the flashing lamp arranged on one side of the support and continuous buzzing alarming of the buzzing baffle arranged on the outer side of the support.
