The protective shell 4 is rotatably mounted on the base plate 1. The device is characterized by: a first vertical plate 5 fixedly mounted on the base plate 1; a second vertical plate 6 fixedly mounted on the side of the mounting plate 2 opposite to the first vertical plate 5; the protective shell 4 being a U-shaped shell with an opening facing downwards; the upper end of the protective shell 4 being rotatably mounted on the base plate 1 via a hinge shaft; and a locking device for fixing the position of the protective shell 4 fixedly mounted on the lower end of the protective shell 4. The left and right sides of the protective shell 4 are respectively connected to... The first vertical plate 5 and the second vertical plate 6 are in close sliding contact with each other on their corresponding sides. Several dovetail grooves 7 are opened on the upper side of the base plate 1. Dovetail sliders 8 are fixedly installed on the lower side of the mounting plate 2 corresponding to the dovetail grooves 7. The dovetail sliders 8 are slidably installed in the corresponding dovetail grooves 7. In this embodiment, there are two dovetail grooves 7 and two dovetail sliders 8. The inner wall of the dovetail groove 7 is in sliding contact with the corresponding side wall of the dovetail slider 8. A strip-shaped locking block 9 is fixedly installed on the side of the protective shell 4 near the second vertical plate 6. A corresponding L-shaped locking block 10 is fixedly installed on the second vertical plate 6. The strip-shaped locking block 9 can engage with the L-shaped locking block 10. This utility model has a simple structure and ingenious design. It does not require moving the gas alarm device 3. Only the protective shell 4 needs to be opened to inspect the gas alarm device 3. At the same time, the gas alarm device 3 can be removed from the base plate 1 for easy replacement of the gas alarm device 3 or the base plate 1. The structure is more reasonable, and the assembly and disassembly operations are simple. It can meet practical needs and is suitable for promotion. When using this utility model, firstly, the base plate 1 is fixedly installed on the wall. Then, the dovetail slider 8 on the mounting plate 2 is aligned with the dovetail groove 7 on the base plate 1, so that the dovetail slider 8 is slidably installed into the corresponding dovetail groove 7 until the right side wall of the second vertical plate 6 abuts and contacts the corresponding side wall of the base plate 1, thereby installing the gas alarm device 3 on the mounting plate 2 onto the base plate 1. Then, the protective shell 4 is rotated to slide along the corresponding side walls of the first vertical plate 5 and the second vertical plate 6, so that it completely covers the gas alarm device 3. The position of the protective shell 4 and the base plate 1 is fixed by the snap-fit ​​device, thereby protecting the gas alarm device 3. The cooperation of the strip-shaped snap-fit ​​block 9 and the L-shaped snap-fit ​​block 10 can fix the second vertical plate 6 when the protective shell 4 completely covers the gas alarm device 3, preventing the second vertical plate 6 from shifting to the left.

[0017] Specifically, as shown in the figure, the gas alarm device 3 in this embodiment includes a main board 20, which is fixedly mounted on the mounting plate 2. A gas detection alarm module 21 and an alarm sounder 22 are fixedly mounted on the main board 20. A sensor probe 23 is fixedly connected to the gas detection alarm module 21. The gas detection alarm module 21 on the left side of the main board 20 is used to detect the concentration of gas in the air, and the alarm sounder 22 on the right side of the main board 20 is used to emit a sound to alert on-site personnel. The sensor probe 23 is fixedly connected to the gas detection alarm module 21 to detect the concentration of gas in the air.

[0018] Furthermore, as shown in the figure, in this embodiment, a through hole 30 is provided on the second vertical plate 6, through which the sensing probe 23 can extend. The sensing probe 23 extends from the through hole 30 to detect gas leaks in the external environment.

[0019] Furthermore, as shown in the figure, the snap-fit ​​device in this embodiment includes two wedge-shaped snap-fit ​​blocks 40 fixedly installed on the lower side of the protective shell 4. Grooves 41 are formed on the base plate 1 corresponding to the wedge-shaped snap-fit ​​blocks 40. Two symmetrically distributed grooves 41 are formed on the lower side of the base plate 1. Slide rods 43 are elastically installed in the grooves 41 via springs 42. One end of the spring 42 is fixedly connected to the inner wall of the groove 41, and the other end is fixedly connected to the side wall of the slide rod 43. Through slots 44 are formed on the upper side of the grooves 41, connecting the grooves 41 to the upper side of the base plate 1. By simultaneously pushing the two slide rods 43 towards the springs 42 with a finger, the two slide rods 43 move inward within their respective grooves 41, causing the slide rods 43 to no longer snap into the corresponding wedge-shaped snap-fit ​​blocks 40, thereby releasing the restriction on the protective shell 4. At this time, the protective shell 4 can rotate.

[0020] Furthermore, as shown in the figure, in this embodiment, sliding grooves 50 are respectively formed on the side wall of the groove 41, and the sliding rods 43 are slidably installed in the corresponding sliding grooves 50. The inner wall of the sliding groove 50 and the corresponding side wall of the sliding rod 43 are in sliding contact. Through the guiding function of the sliding groove 50, the sliding rod 43 can be guided to prevent it from deviating when moving in the groove 41.

[0021] Furthermore, as shown in the figure, several countersunk holes 60 are formed on the base plate 1 in this embodiment. The mounting assembly is fixed to the wall by installing fastening bolts in the countersunk holes 60.

[0022] Furthermore, as shown in the figure, the protective shell 4 in this embodiment has several ventilation slots on its side. The ventilation slots facilitate the gas alarm device 3 in detecting gas, and also facilitate the sound transmission of the alarm sounder 22.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
