Abstract

The invention belongs to the field of a fire alarm, and particularly to an explosion-proof hand-operated fire alarm. For aiming at problems of direct exposure of an outer side of a traditional fire alarm to outside, easy insect entering from a slit of the fire alarm, and fire alarm malfunction in a severe condition, the invention provides the explosion-proof hand-operated fire alarm which is characterized in that the explosion-proof hand-operated fire alarm comprises a mounting enclosure and an alarm device which is connected with the mounting enclosure; a mounting board fixedly sleeves the outer ring at one end, which is next to the mounting enclosure, of the alarm; one side, which is far from the mounting enclosure, of the mounting board is provided with an abutting sleeve ring; one endat one side, which is far from the mounting board, of the abutting sleeve ring is provided with a fixed base that is welded; a rotating shaft is movably sleeved on the fixed base; and the outer ring of the rotating shaft is fixedly sleeved with a connecting rod. According to the explosion-proof hand-operated fire alarm, the insulating enclosure is added outside the alarm, thereby preventing entering of insects through the slit of the alarm, protecting safety of the alarm, improving the explosion-proof function of the alarm, and realizing convenient and quick mounting and detachment of the insulating enclosure, wherein the insulating enclosure is fixed by means of an interlocking mode.

Description

technical field [0001] The invention relates to the technical field of fire alarms, in particular to an explosion-proof manual fire alarm. Background technique [0002] Manual fire alarm is a type of equipment in the fire alarm system. When a fire occurs and the fire detector does not detect the fire, the personnel manually press the manual fire alarm button to report the fire signal. The outside of the traditional fire alarm is directly exposed In the outside world, insects are easy to enter from the gaps in the fire alarm, and in severe cases, the fire alarm will fail. For this reason, an explosion-proof manual fire alarm is required. Contents of the invention [0003] The explosion-proof manual fire alarm proposed by the present invention solves the problem that the outside of the traditional fire alarm is directly exposed to the outside world, insects are easy to enter from the gap of the fire alarm, and the fire alarm fails in severe cases. [0004] In order to achie...
