The four sides of the fixed plate 4 are slidably connected to multiple sliding plates 5. Each sliding plate 5 is rotatably connected to an extension plate 6 on the side away from the fixed plate 4. The end of each sliding plate 5 away from the extension plate 6 is provided with a limit, so that the sliding plate 5 will not completely fall out of the fixed plate 4. The extension plate 6 and the sliding plate 5 cooperate with each other to form a fixed structure of the detection box 1.

[0025] It should be noted that a plurality of limiting holes are provided inside the detection box 1 for fixing the combustible gas detector, which includes a controller, a battery, a combustible gas detector, an alarm light and an alarm. The alarm light and the alarm are connected to the controller through internal circuits. The gas guide pipe and the alarm light connection line of the combustible gas detector pass through the side wall of the detection box 1 through the detection tube 3. The alarm light and the alarm are fixedly connected to the outside of the detection box 1. When the combustible gas detector detects combustible gas, it will sound an alarm through the alarm light and the alarm. The combustible gas detector is a prior art and will not be described in detail here.

[0026] When in use, when assembling and fixing on a conventional wall, it can be fixed directly through the fixing plate 4. When the device needs to be assembled and fixed near a perforated board or a shelf, the fixing plate 4 can be fixed through the sliding plate 5, and then the device can be assembled and fixed indirectly. When the device needs to be hung somewhere, the extension plate 6 can be rotated and unfolded, and the device can be hung, assembled and fixed through the extension plate 6.

[0027] Further, by Figure 1 - Figure 4 As shown, in order to facilitate the maintenance of the device, a plurality of grooves 7 are provided around the box cover 2, each groove 7 has a threaded hole 8 formed inside, and a threaded groove 9 is provided inside the detection box 1 at a position corresponding to each threaded hole 8.

[0028] When in use, the threaded hole 8 and the threaded groove 9 can be fixed by bolts, so that the box cover 2 and the detection box 1 can be fixed.

[0029] Further, by Figure 1 - Figure 4 As shown, in order to facilitate the operation of the staff and achieve the purpose of fixing the fixed plate 4 while fixing the sliding plate 5, a fixing groove 10 is opened in the middle of each sliding plate 5, and a driven plate 11 is rotatably connected to the interior of each fixing groove 10. A fixing hole 12 is opened at one end of each sliding plate 5 close to the corresponding extension plate 6, and a fixing long hole 13 is opened on each driven plate 11 at a position corresponding to the fixing hole 12;

[0030] Further, by Figure 1 - Figure 4 As shown, in order to make the device more stable, each driven plate 11 is fixedly connected to a side close to the detection box 1 with a plurality of fixing bars 14, each fixing bar 14 is semicircular, and the radius of each fixing bar 14 gradually increases in the direction away from the fixed long hole 13;

[0031] During use, when the sliding plate 5 needs to be used for auxiliary fixation, the sliding plate 5 can be pulled out relative to the fixed plate 4. At this time, the fixing hole 12 and the fixing long hole 13 are exposed, and the sliding plate 5 can be fixed by passing the bolt through the fixing hole 12. During the process of tightening the bolt, the bolt will press the side of the fixing long hole 13 backward, thereby causing the driven plate 11 to rotate. At this time, the driven plate 11 drives each fixing bar 14 to rotate, so that each fixing bar 14 contacts the detection box 1. Under the action of friction, the sliding plate 5 is fixed relative to the detection box 1 and the fixed plate 4. By designing the fixing bars 14 with different radii, after the driven plate 11 rotates a certain angle, each fixing bar 14 can contact the rear side plane of the detection box 1 almost at the same time, thereby maximizing the effect of the fixing bar 14.

[0032] Further, by Figure 1 - Figure 4 As shown, in order to facilitate the disassembly and assembly of the device, a reset spring 15 is provided on the rear side of each driven plate 11. Each reset spring 15 is arranged between the driven plate 11 and the fixing groove 10, and each reset spring 15 is concentrically arranged with the corresponding fixing hole 12;

[0033] During use, when the bolt inside the fixing hole 12 is removed by the reset spring piece 15 , the driven plate 11 is rotated and reset under the action of the reset spring piece 15 .

[0034] Further, by Figure 1 - Figure 4 As shown, in order to achieve the purpose of hanging and fixing the device, an auxiliary hole 16 is opened in the middle of each extension plate 6;

[0035] During use, when the device needs to be hung and fixed, the sliding plate 5 on the upper side of the fixing plate 4 can be pulled out, and the corresponding extension plate 6 can be flipped open. At this time, the extension plate 6 can be fixedly connected to the horizontal hanging plane through the auxiliary hole 16, which facilitates the fixation of the device.

[0036] Further, by Figure 1 - Figure 4 As shown, in order to facilitate the staff to fix the fixing plate 4, a plurality of circular holes 17 are opened around the fixing plate 4;

[0037] When in use, the fixing plate 4 can be fixed conventionally through the circular hole 17 .

[0038] When the present invention is used, when it is fixed on a conventional wall, it can be fixed directly through the fixing plate 4. When the device needs to be fixed near a perforated board or a shelf, the fixing plate 4 can be fixed by the sliding plate 5, thereby indirectly fixing the device. At this time, the sliding plate 5 can be pulled out relative to the fixing plate 4, and the fixing hole 12 and the fixing long hole 13 are exposed. The sliding plate 5 can be fixed by passing the bolt through the fixing hole 12. During the process of tightening the bolt, the bolt will press the side of the fixing long hole 13 backward, thereby causing the driven plate 11 to rotate. At this time, the driven plate 11 drives each fixing bar 14 to rotate, so that each fixing bar 14 contacts the detection box 1. Under the action of friction, the sliding plate 5 is fixed relative to the detection box 1 and the fixed plate 4. By designing the fixing bars 14 with different radii, after the driven plate 11 rotates a certain angle, each fixing bar 14 can almost simultaneously contact the rear plane of the detection box 1, thereby maximizing the effect of the fixing bars 14. When the device needs to be hung somewhere, the extension plate 6 can be rotated and unfolded, and the device can be hung and fixed through the extension plate 6.

[0039] The utility model has a novel structure, ingenious conception, simple and convenient operation, and effectively achieves the purpose of being able to fix the device in a variety of ways through this design, achieves the purpose of being able to conveniently repair the device, facilitates the operation of the staff, makes the device more stable, and facilitates the disassembly and assembly of the entire device. In addition, through the mutual cooperation between the sliding plate 5 and the driven plate 11, it is possible to perform only unilateral fixation or bilateral fixation when there is insufficient space at the device installation location (such as a shelf), and the fixed position can be adjusted according to the shelf height. It has a wide range of applications, and the position of the adjusting sliding plate 5 can adapt to the installation hole of the wall or other installation locations.
