| description | The utility model discloses a portable gas safety detector which comprises a protective shell and a mounting seat, a gas detector body is fixedly mounted on the inner wall of the protective shell, the inner wall of the protective shell is rotatably connected with a wind-up roller through a connecting shaft, a through groove is formed in the inner wall of the wind-up roller, a wire is wound on the surface of the wind-up roller, and the surface of the wind-up roller is fixedly connected with the mounting seat. An electric slip ring is arranged on the right side surface of the gas detector body. By arranging the winding roller and the mounting seat, when gas in a deep hole is detected, the winding roller is firstly rotated to unwind the wire, and when the winding roller rotates, one end of the wire is connected with the gas detector body through the electric slip ring, so that the wire can be prevented from interfering with the rotation of the winding roller; therefore, the semiconductor gas detection sensor on |
