[0002] By continuously monitoring the gas through a detector and converting the gas concentration and system information into digital signals, which are then transmitted to the gas alarm controller, the gas leak alarm is a key safety device used to detect leaks of combustible gases and issue timely warnings.

[0003] In practical use, existing alarm devices are usually installed by fastening screws for pipe mounting, ceiling mounting, or wall mounting. However, as the usage time increases, the slight vibration generated during the operation of the alarm device can cause the fastening screws to loosen, and in severe cases, even cause the fastening screws to fall off. This results in a lack of stability after installation. Therefore, there is a need to provide an alarm device that can detect gas leaks and improve the stability and reliability of the alarm device after installation. Utility Model Content

[0004] The purpose of this utility model is to provide an alarm device that can detect gas leaks, in order to solve the problem mentioned in the background art. In actual use, existing alarm devices are usually installed by fastening screws for pipe mounting, ceiling mounting, or wall mounting. However, as the usage time increases, the alarm device will generate slight vibration during operation, which will cause the fastening screws to loosen. In severe cases, the fastening screws may even fall off, resulting in a lack of stability after installation.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an alarm device that can detect gas leaks, comprising:

[0007] The mounting components include an alarm housing, an extension plate, and mounting holes;

[0008] The positioning component includes a side plate, a turntable, a rotating shaft, a positioning ring, a support block, an internal threaded ring, a threaded rod, a clamp, and a rubber block. The lower part of both sides of the outer surface of the alarm device is symmetrically connected to the turntable. The rotating shaft is connected to one side of the turntable, the side plate is connected to one side of the outer surface of the rotating shaft, the support block is connected to the upper part of the other side of the outer surface of the side plate, and the positioning ring is connected to one side of the outer surface of the support block.

[0009] Furthermore, an internal threaded ring is connected to the lower part of one side of the outer surface of the side plate, a threaded rod is connected to the middle of the internal threaded ring, and a handle is rotatably connected to one side of the threaded rod.

[0010] Furthermore, a clamp is connected to the other side of the outer surface of the threaded rod. The clamp is made of rubber and is clamped to the lower part of both sides of the outer surface of the alarm housing.

[0011] Furthermore, extension plates are symmetrically connected to both sides of the outer surface of the alarm housing, and mounting holes are provided in the middle of the extension plates.

[0012] Furthermore, it also includes protective components, which include a first retaining ring, a second retaining ring, a first inner rubber ring, a second inner rubber ring, an insert plate, a slot, an inner groove, a mating block, a limiting block, and a positioning plate. The two ends of the inner surface of the positioning ring are respectively connected to the first inner rubber ring and the second inner rubber ring. The first retaining ring is connected to one end of the first inner rubber ring, and the second retaining ring is connected to one end of the second inner rubber ring. The other end of the first inner rubber ring is connected to the insert plate, and the other end of the second inner rubber ring has a slot. The insert plate is inserted into and connected to the inside of the slot.

[0013] Furthermore, the upper and lower parts of one end of the first retaining ring are connected to a docking block, and the upper part of one end of the docking block is connected to a positioning plate.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] This invention, using a turntable, rotating shaft, and positioning ring, allows the alarm housing to be installed in the desired position. Fastening screws are inserted into the mounting holes to secure the alarm housing. Then, the side plates rotate within the turntable via the rotating shaft, causing the positioning rings to engage with the fastening screws. Next, rotating the threaded rod causes the clamping plate to hold the lower part of both sides of the alarm housing's outer surface, fixing the position of the rotated side plates. The positioning rings position the fastening screws, preventing slight vibrations during alarm operation from causing the fastening screws to loosen or even fall off in severe cases, thus improving the stability and reliability of the alarm housing after installation.

[0016] Based on the aforementioned beneficial effects, by providing a first rubber inner ring and a second rubber inner ring inside the positioning ring, the positioning ring is permanently fastened to the outside of the fastening screw. The inner wall of the positioning ring will rub against the fastening screw. The insert plate is inserted into the slot, and the first and second rubber inner rings are installed inside the positioning ring. When the positioning ring is fastened to the outside of the fastening screw, the first and second rubber inner rings will directly contact the fastening screw, avoiding the loosening phenomenon caused by the friction between the inner wall of the positioning ring and the fastening screw when it is permanently fastened to the outside of the fastening screw, thus improving the protective performance.

[0029] Please see Figure 1-4As shown, this embodiment is an alarm device capable of detecting gas leaks, comprising:

[0030] The mounting components include an alarm housing 11, an extension plate 12, and mounting holes 13.

[0031] The positioning component includes a side plate 21, a turntable 22, a rotating shaft 23, a positioning ring 24, a support block 25, an internal threaded ring 26, a threaded rod 27, a clamping plate 28, and a rubber block. The turntable 22 is symmetrically connected to the lower part of both sides of the outer surface of the alarm device. The rotating shaft 23 is connected to one side of the turntable 22. The side plate 21 is connected to one side of the outer surface of the rotating shaft 23. The support block 25 is connected to the upper part of the other side of the outer surface of the side plate 21. The positioning ring 24 is connected to one side of the outer surface of the support block 25.

[0032] The side plates 21 on both sides rotate inside the turntable 22 via the rotating shaft 23, so that the positioning ring 24 is engaged with the outside of the fastening screw. Then, the threaded rod 27 is rotated so that the clamping plate 28 is clamped on the lower part of both sides of the outer surface of the alarm housing 11, fixing the position of the side plates 21 after rotation, and using the positioning ring 24 to position the fastening screw.
