Problems solved by technology
[0003] However, there are still deficiencies in the above-mentioned technology, because the alarm body needs to be connected with other electric wires during installation, and when the alarm body is screwed when the thread is twisted, the upper wire of the alarm body is connected The direction of the mouth will change. In the case of other wires with limited distance, it is not easy to connect with the alarm body. If the alarm body is not tightened completely, it is worried that the alarm body will become loose in the future and there will be a drop. The possibility of falling, shorten the service life of the alarm body

Abstract
The invention belongs to the technical field of alarm equipment, in particular to an explosion-proof audible and visual alarm. The explosion-proof audible and visual alarm comprises a case, wherein the bottom of the case is provided with an opening; an alarm body is mounted inside the case in a threaded manner; an annular box with an opening at the bottom is fixedly arranged on the case in a sleeving manner; two sides of the alarm body are both fixedly equipped with first strip-shaped blocks; first grooves are formed in the bottoms of the first strip-shaped blocks; each of the first grooves isprovided with an opening on one side; second strip-shaped blocks are slidably mounted in the first grooves; the side, away from the alarm body, of each of the second strip-shaped blocks extends to the outside of the corresponding first groove; and three annular grooves are formed in the inner wall of the annular box. The explosion-proof audible and visual alarm is simple in structure and high inpracticability. The explosion-proof audible and visual alarm can enable the alarm body to adjust the connection direction of an electric wire connection port during installation while enabling the alarm body not to move, thereby preventing the alarm body from falling off due to the untightened condition, prolonging the service life of the alarm body, and simplifying and facilitating the operation.
Description
technical field [0001] The invention relates to the technical field of alarm equipment, in particular to an explosion-proof sound and light alarm. Background technique [0002] An alarm is an electronic product that reminds or warns us that we should take certain actions in the form of sound, light, air pressure, etc., in order to prevent or prevent the consequences of an event. Alarms are divided into mechanical alarms and electronic alarms. Alarm, after retrieval, the authorized publication number is CN201765652U patent document, which discloses an explosion-proof sound and light alarm, including a lampshade, a threaded joint is fixed on the cavity, a lower cover is threadedly connected to the right end of the cavity, the cavity and the lower A front inlay cover is installed in the cavity at the connection of the cover. The left end of the cavity is threaded to connect a cover, and the left end of the cover is threaded to a lampshade. Mechanized mass production, using the...
