Alarm roadblock for position placement and manufacturing method of alarm roadblock

Abstract

The invention relates to the field of roadblocks, and discloses an alarm roadblock for position placement and a manufacturing method thereof, the roadblock comprises a frame mechanism, a support mechanism and an alarm mechanism; the frame mechanism comprises a lower plate, vertical rods located in the vertical direction are fixed to the two sides of the lower plate, an upper plate located above the lower plate is fixed between the two vertical rods, and a plurality of detachable transverse rods evenly distributed in the two vertical rods are arranged between the upper plate and the lower plate. The supporting mechanism comprises a base fixed to the bottom end of the lower plate. The alarm mechanism comprises a dark glass tube which is installed between the two vertical rods and located above the upper plate, a foam layer is attached to the inner wall of the dark glass tube, dry ice is wrapped in the foam layer, and openings in the two sides of the dark glass tube are connected with plungers. When the roadblock is knocked down, the dark glass tube falls and is broken to expose dry ice in the dark glass tube, and the dry ice is in contact with air to sublimate into carbon dioxide gas and form white fog, so that damage of the roadblock can be known in time.

Description

technical field [0001] The invention belongs to the field of roadblocks, in particular to an alarm roadblock for setting up positions and a manufacturing method thereof. Background technique [0002] Barricades are divided into fixed barricades and movable barricades. [0003] Fixed roadblocks cannot be moved once they are set up, so the flexibility is not high; while some movable roadblocks can be raised and lowered, and some can be moved at will, with high flexibility, so they are more and more widely used. [0004] For the roadblocks used on the battlefield, the function of the roadblock is not only to block, but also to warn passers-by not to pass by. [0005] But existing roadblock has following several problems, one: install trouble, need a lot of time to install roadblock; In order to solve this problem, a kind of warning barricade and its manufacturing method for setting up a position are proposed here. Contents of the invention [0006] In order to solve the pr...
