Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Specifically, in the process of the multifunctional gas leak alarm performing its working duties, the plastic shell 4 plays an effective protective role on the control panel 3, extending its service life. The upper shell 7 and the lower shell 5 provide a protective barrier for the display panel 6 by snapping together. The protective cover 10 provides an additional protective layer for the sensor to protect it from interference from various environmental factors, thereby ensuring the sensitivity and accuracy of the sensor. The adapter 9 realizes the connection between the detector shell 1 and the protective cover 10, ensuring the structural stability and overall performance of the entire alarm.

[0034] Reference Figure 1 、 Figure 3 and Figure 5 The clamping mechanism 2 includes a groove 201, which is provided in the middle of the right side of the inner wall of the detector shell 1. The inner bottom end of the groove 201 is rotatably connected to a rotating gear 202, and the outer wall left side of the rotating gear 202 is fixedly connected to an arc-shaped clamping plate 1 203, and the inner top of the groove 201 is rotatably connected to a driven gear 204, and the outer wall left side of the driven gear 204 is fixedly connected to an arc-shaped clamping plate 205, the rotating gear 202 and the driven gear 204 are meshed and connected, and the front side of the outer wall of the rotating gear 202 is fixedly connected to a connecting rod 206, and the other end of the connecting rod 206 is fixedly connected to a turning handle 207; the four corners on the front side of the outer wall of the detector shell 1 are threadedly connected with bolts 13, and the detector shell 1 is threadedly connected to the shell cover 11 by the bolts 13;

[0035] Specifically, during the placement of the detection component, the handle 207 is turned. As the handle 207 is turned, the connecting rod 206 will also rotate accordingly, and the rotating gear 202 begins to rotate under the joint action of the connecting rod 206 and the handle 207. Since there is a meshing connection between the driven gear 204 and the rotating gear 202, the driven gear 204 will also start to rotate under the drive of the rotating gear 202. The arc-shaped clamping plate 205 will work together with the arc-shaped clamping plate 1 203 under the action of the driven gear 204 to clamp and fix the detection component together, effectively avoiding unnecessary shaking of the detection component inside the detector shell 1, ensuring the stability and accuracy of the detection process, and using bolts 13 to achieve the connection between the shell cover 11 and the detector shell 1 to ensure the integrity of the detector shell 1.

[0036] Reference Figure 2 and Figure 4 , the rear side of the top of the outer wall of the detector housing 1 is threadedly connected with a fixing plate 14, and fixing holes 15 are opened on the left and right sides of the outer wall of the fixing plate 14; an alarm light 19 is installed on the right side of the outer wall of the detector housing 1, and a threaded coil 20 is opened at the bottom of the alarm light 19;

[0037] Specifically, the detector shell 1 can be fixed at a specified position through the fixing plate 14, and the fixing plate 14 is fixed through the fixing hole 15. The alarm light 19 can effectively provide danger information to the staff, and the connection with the detector shell 1 is achieved through the threaded coil 20 opened at the bottom of the alarm light 19.

[0038] Reference Figure 1 and Figure 3 , an indicator light 16 is installed on the left side of the upper middle part of the upper shell 7, an indicator light 2 17 is installed on the upper middle part of the upper shell 7, and an indicator light 3 18 is installed on the right side of the upper middle part of the upper shell 7; a card slot 21 is opened on the rear side of the outer wall of the shell cover 11, and a gasket 22 is engaged with the inner part of the card slot 21;

[0039] Specifically, the information provided by the display panel 6 is analyzed according to the lighting conditions of the indicator light 16 , the indicator light 2 17 and the indicator light 3 18 . The card slot 21 can engage the gasket 22 , and the gasket 22 can ensure the sealing of the detector housing 1 .

[0040] Working principle: When the multifunctional gas leak alarm is working, the plastic shell 4 protects the control panel 3, the upper shell 7 and the lower shell 5 are engaged to protect the display panel 6, and the protective cover 10 protects the sensor. The connection between the detector shell 1 and the protective cover 10 is achieved through the adapter 9.

[0041] When the detection component is placed inside the detector shell 1, the handle 207 is turned and the connecting rod 206 will rotate at the same time. At this time, the rotating gear 202 starts to rotate under the action of the connecting rod 206 and the handle 207. Since the driven gear 204 is engaged with the rotating gear 202, the driven gear 204 drives the arc-shaped clamping plate 2 205 to cooperate with the arc-shaped clamping plate 1 203 to clamp and fix the detection component under the action of the rotating gear 202, which effectively prevents the detection component from shaking inside the detector shell 1.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
