Physically triggered alarm device for use in monitoring unit

Abstract

The invention discloses a physical trigger type alarm device used in a monitoring unit, relates to the technical field of alarm equipment, and solves the problem that a monitoring camera in an existing alarm device is easily covered by a hydrogen balloon by a thief. The device comprises a carrying shell, a driving rod is rotationally mounted in the middle of the interior of the carrying shell, a shaft rod is rotationally mounted on the left side of the interior of the carrying shell, and the top end of the shaft rod penetrates through the top of the carrying shell; a follow-up gear is arranged on the lower section of the shaft rod; a positioning piece is arranged at the front end of the left side of the top of the carrying shell; the right side of the top of the carrying shell is provided with a sound broadcasting bin cylinder. The top of the sound broadcasting silo is provided with a sound simulating silo. And a plurality of groups of sound playing holes are formed in the circumferential outer wall of the sound playing bin cylinder. According to the invention, the hydrogen balloon is punctured through the puncturing piece, so that the camera equipment is prevented from being covered by the hydrogen balloon and cannot capture and recognize the stealing behavior of a thief in time.

Description

technical field [0001] The invention relates to the technical field of alarm equipment, in particular to a physically triggered alarm device used in a monitoring unit. Background technique [0002] Alarm devices refer to information display devices that indicate failures, accidents or dangerous situations.
