Description

Technical Field

[0001] This utility model relates to the field of gas alarm technology, specifically a prefabricated gas alarm. Background Technology

[0002] A gas alarm is a safety device used to detect the concentration of combustible gases (such as natural gas and liquefied petroleum gas) in the air. When the gas concentration exceeds a preset safety value, the alarm will emit an audible and visual alarm to remind the user to take timely measures to prevent fires or explosions. It is typically installed in gas-using areas such as kitchens and bathrooms, monitoring the gas concentration in the environment in real time through built-in sensors. Gas alarms are available in both residential and industrial versions, featuring high sensitivity, fast response, and good stability, making them essential devices for ensuring safety in homes and public places. Regular maintenance and battery replacement ensure normal operation. Different types of gas require different gas alarms for real-time monitoring, but the body of a conventional gas alarm is installed inside the casing and is difficult to disassemble; the body fits perfectly with the bottom shell, making it impossible to replace the body. Utility Model Content

[0023] Please see Figures 1-3 This utility model provides a technical solution: a prefabricated gas alarm, comprising;

[0024] The gas alarm body 300 has an assembly structure on its outer side, which includes a mounting base 100, a gas alarm housing A400, and a gas alarm housing B500.

[0025] Gas alarm housing A400 and gas alarm housing B500 are located at the top of the mounting base 100 at both ends. Near one end, there are two symmetrical limiting shafts A401 on both sides. Gas alarm housing B500 near one end has two symmetrical limiting shafts B501 on both sides.

[0026] The mounting base 100 has multiple integrally fixed guide frames 102 at both ends. Each guide frame 102 has a guide groove. The limiting shaft A401 passes through the guide frame 102 and is slidably connected to the mounting base 100. The limiting shaft B501 passes through the guide frame 102 and is slidably connected to the mounting base 100.

[0027] The ends of the gas alarm housing A400 and the gas alarm housing B500 abut against each other, and the two ends of the gas alarm body 300 are respectively embedded inside the gas alarm housing A400 and the gas alarm housing B500.

[0028] Furthermore, both the gas alarm housing A400 and the gas alarm housing B500 have hollow interiors. The top of the gas alarm housing A400 has an embedded acrylic panel A402, and the top of the gas alarm housing B500 has an embedded acrylic panel B502. The gas alarm unit 300 inside can be observed through the acrylic panels A402 and B502, thereby allowing observation of the status of the indicator lights on the gas alarm unit 300.

[0029] Furthermore, both the gas alarm housing A400 and the gas alarm housing B500 are provided with multiple air inlets, which allow the gas alarm body 300 to come into contact with the outside air, thereby enabling real-time monitoring of gas leaks.

[0030] Furthermore, the guide grooves on the guide frame 102 are all "L" shaped, and the limiting shafts A401 and B501 can slide and rotate inside the guide frame 102. By sliding the gas alarm housings A400 and B500 towards both ends of the mounting base 100, a gap is created between the gas alarm housings A400 and B500. Then, the gas alarm housings A400 and B500 are rotated so that their orientation is upward, at which point they can be separated from the gas alarm body 300, and different gas alarm bodies 300 can be replaced to detect different types of gas. Moreover, the bottoms of the gas alarm housings A400 and B500 are both through-hole, so they are not obstructed when rotating.

[0031] Furthermore, an adhesive plate 200 is attached to the bottom of the mounting base 100, which allows the device to be attached near the gas pipeline for real-time gas monitoring.

[0032] Furthermore, both sides of the gas alarm housing A400 and gas alarm housing B500 are provided with through slots. A pressure plate 601 is embedded inside each slot.

Each connector 602 has a bolt 604 at its top for installation. The base 100 has two integrally fixed threaded tubes 101 on both sides. The bottom of the bolt 604 passes through the connector 602 and is embedded in the threaded tube 101. The two clips 600 can be tightened by the connector 602 and the pin 603, so that the ends of the gas alarm housing A400 and the gas alarm housing B500 are tightly fitted. The bolt 604 is used to tighten the connector 602 to limit and fix it, preventing the connector 602 from falling off. The pressure plate 601 is pressed on the top of the gas alarm body 300 to prevent the gas alarm body 300 from shaking.

[0033] Working principle: When in use, attach the gas alarm body 300 to the top of the mounting base 100, then rotate the gas alarm housing A400 and gas alarm housing B500 to fasten them to both ends of the gas alarm body 300. At this time, insert the pins 603 at both ends of the connector 602 into the two clips 600, and then tighten the bolts 604 to limit the position, so that the gas alarm body 300 is tightened and fixed. The device can be pasted near the gas pipeline through the adhesive plate 200, so as to monitor the gas in real time.

[0034] Furthermore, the guide grooves on the guide frame 102 are all "L" shaped. The limiting shafts A401 and B501 can slide and rotate inside the guide frame 102. By sliding the gas alarm housings A400 and B500 towards both ends of the mounting base 100, a gap is created between the gas alarm housings A400 and B500. Then, the gas alarm housings A400 and B500 are rotated so that their orientation is upward. At this point, they can be separated from the gas alarm body 300, and different gas alarm bodies 300 can be replaced to detect different types of gas.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
