Description

Technical Field

[0001] The utility model relates to the technical field of fire alarms, in particular to a fire early warning alarm. Background Art

[0002] A fire alarm is a device used to detect fires and sound the alarm. It usually includes sensors such as smoke detectors and temperature detectors, as well as components such as alarm hosts and alarm speakers. Fire alarms are very important for early detection of fires, because early fires often do not produce a lot of smoke and flames, but there are obvious changes in temperature and smoke. If a fire can be discovered and an alarm can be sounded in time when it first starts, measures can be taken quickly to extinguish the fire source and prevent the fire from expanding and spreading.

[0003] When installing the existing fire warning alarm, most of them are directly fixed on the ceiling of the room for easy detection. However, the fire alarm is a warning device and has a long standby time. After being placed for a long time, staff are required to detect it to ensure its normal function and replace the faulty fire alarm. However, it is not convenient to disassemble and replace it during replacement, and the steps are cumbersome, which affects the maintenance efficiency. In order to solve the above problems, while facilitating the installation of the fire alarm, it is also convenient for it to be repaired and replaced, thereby speeding up work efficiency. For this reason, we propose a fire warning alarm. Utility Model Content

[0017] 1. The fire warning alarm, through the mutual cooperation between the clamping end and the clamping groove, when it is necessary to install the mounting ring plate, it is only necessary to align the clamping ends on both sides with the clamping grooves opened at the bottom of the mounting plate, and then push the clamping ends into the inside of the clamping grooves. When the clamping ends enter the inside of the clamping grooves and contact with the limiting ends, the top blocks on both sides of the clamping ends are fitted with the limiting ends, and then the limiting ends are squeezed along the inclined surfaces of the limiting ends to make the squeezing springs contract. Then the clamping ends will pass through the two groups of limiting ends, and the two groups of limiting ends will be pushed out by the springs, thereby limiting the clamping ends and completing the installation of the mounting ring plate. When disassembling, it is only necessary to pinch the clamping ends and pull them down hard, which is more convenient.

When installing the alarm, first send the insertion end into the installation ring plate through the insertion groove opened at the bottom of the installation ring plate, and then rotate the alarm as a whole along the rotating slide groove opened on the installation ring plate, so that the connecting piece fixedly installed on the top of the alarm rotates along the rotating slide groove as the alarm rotates, until the limit groove opened on the insertion end fits with the limit column fixedly installed on the top of the installation ring plate, until the limit column contacts the bottom of the inner wall of the limit groove, The alarm can be pulled to make the connecting piece sink on the top of the mounting ring plate, so that the insertion end is snap-fitted and installed inside the slot, completing the overall installation of the connecting piece and the alarm. When the alarm needs to be repaired, it is only necessary to lift the alarm first to make the insertion end pass through the inside of the slot, and then rotate the alarm counterclockwise to make the insertion end rotate together on the top of the mounting ring plate until the insertion end returns to the position of the insertion slot, and then the alarm can be pulled out as a whole. Installation and disassembly are more convenient, which can effectively improve work efficiency and is more practical. BRIEF DESCRIPTION OF THE DRAWINGS
