The display 2 adopts a high-definition liquid crystal display screen, which can clearly display various data and parameters of natural gas analysis, such as the component ratio, pressure and temperature of natural gas. The top end of the analysis instrument shell 1 is slidably connected with a cover plate 3. The cover plate 3 is made of a material matched with the gas analysis instrument shell 1, so as to effectively prevent dust and moisture from entering the instrument interior in the closed state. The sliding connection mode of the cover plate 3 can be realized through the guide rail arranged on the top of the gas analysis instrument shell 1, so that the cover plate 3 can be smoothly opened and closed. The middle part of the cover plate 3 is rotatably connected with a power transmission rotating assembly, and the rotating assembly comprises a rotating rod 4;

[0036] The surface of the rotating rod 4 is smooth to reduce friction when rotating. The outer part of the rotating rod 4 is rotatably connected to the middle inner wall of the cover plate 3. This rotatable connection can be achieved by installing a bearing on the inner wall of the cover plate 3, so that the rotating rod 4 can rotate smoothly. The top side of the rotating rod 4 is fixedly connected with a handle 5. The handle 5 makes it more comfortable and convenient for users to operate. The bottom side of the rotating assembly is fixedly connected with a circular plate 6. The circular plate 6 ensures that the power can be transmitted stably when rotating. The bottom side of the rotating rod 4 is fixedly connected to the top side of the circular plate 6. This fixed connection can be achieved by welding, threaded connection or using fasteners, etc., to ensure the firmness of the connection. The bottom side of the circular plate 6 is fixedly connected with two push columns 7. The fixed connection of the push column 7 with the circular plate 6 can be achieved by welding or using screws, etc., to ensure that it will not loosen during pushing.

[0037] The far side of each of the two opening plates 8 is fixedly connected with a sliding plate 9. The fixed connection of the sliding plate 9 with the opening plate 8 can be achieved by welding, screw connection or using adhesives, etc., to ensure the firmness of the connection. The outer part of each of the two sliding plates 9 is slidably connected to the left and right inner walls of the cover plate 3. The left and right inner walls of the cover plate 3 are provided with special slides or guide rails, so that the sliding plates 9 can slide smoothly therein.

[0038] Referring to Figure 1 and Figure 4 , the bottom front end of the gas analysis instrument shell 1 is fixedly connected with an inlet pipe 13. The fixed connection of the inlet pipe 13 with the gas analysis instrument shell 1 can be achieved by welding, to ensure the firmness and sealing of the connection. The front bottom of the gas analysis instrument shell 1 is fixedly connected with an outlet pipe 14. The material and connection method of the outlet pipe 14 are similar to those of the inlet pipe 13, and its function is to discharge the analyzed natural gas from the instrument. The outer part of the inlet pipe 13 is fixedly connected with a limiting ring 15. The limiting ring 15 is fixedly connected to the outer part of the inlet pipe 13 by welding. The front side of the limiting ring 15 is fixedly connected with a reset assembly for abutting against the subsequent components. The reset assembly includes a spring 16.

[0039] The rear end of the spring 16 is fixedly connected to the front side of the limiting ring 15, and the fixed connection can be achieved by welding. The front end of the spring 16 is fixedly connected to the sealing ring 17. The sealing ring 17 is made of elastic materials such as rubber or silicone, and its shape and size are matched with the inlet pipe 13 to ensure effective sealing when the connecting pipe 19 is connected, preventing natural gas leakage. The inside of the sealing ring 17 is slidably connected to the outside of the inlet pipe 13. The outside of the inlet pipe 13 is threadedly connected to the threaded cylinder 18. The threads inside the threaded cylinder 18 are matched with the threads outside the inlet pipe 13, and the threaded cylinder 18 can be connected and detached with the inlet pipe 13 by rotating. The front side of the sealing ring 17 is in contact with the rear side of the threaded cylinder 18, and when the threaded cylinder 18 is tightened, it will push the sealing ring 17 to move backward, so that it is tightly fitted with the connecting pipe 19, achieving sealing. The front end of the threaded cylinder 18 is fixedly connected to the connecting pipe 19.

[0040] Referring to Figure 1 , Figure 6 and Figure 7 , the rear side of the gas analysis instrument shell 1 is fixedly connected to the support frame 20. The rear end of the gas analysis instrument shell 1 is rotatably connected to two rotating plates 21. The rotating plates 21 are used to support the rotation of subsequent components. The rotating connection between the rotating plates 21 and the gas analysis instrument shell 1 can be achieved by installing a rotating shaft at the rear of the gas analysis instrument shell 1, so that the rotating plates 21 can freely rotate. The bottom side of the rear end of the two rotating plates 21 is fixedly connected to the strip-shaped plate 22. The length and width of the strip-shaped plate 22 are determined according to the structure of the rotating plate 21. The fixed connection between the strip-shaped plate 22 and the rotating plate 21 can be achieved by welding, to ensure the firmness of the connection. The bottom side of the strip-shaped plate 22 is provided with a plurality of arc-shaped openings 24. The arc-shaped openings 24 are used to bundle the cables. The top side of the strip-shaped plate 22 is fixedly connected to the handle 23. The handle 23 is convenient for users to carry the instrument more comfortably and conveniently. The left and right ends of the support frame 20 are provided with strip-shaped openings 25. The shape and size of the strip-shaped openings 25 are determined according to the movement trajectory of the rotating plate 21, to ensure that the rotating plate 21 will not be hindered when rotating. The bottom side of the strip-shaped plate 22 is fixedly connected to the elastic members 26 at the left and right ends. The elastic members 26 function to limit and engage when the strip-shaped plate 22 is put down.

[0041] Working principle: first, the connecting pipe 19 is connected with the external natural gas pipeline. By rotating the threaded cylinder 18, it is connected and screwed outside the entering pipe 13. During the screwing process, the threaded cylinder 18 pushes the sealing ring 17 to move backward, and the sealing ring 17 is tightly attached to the connecting part of the connecting pipe 19 and the entering pipe 13 under the action of spring 2 16, which ensures that the natural gas cannot leak and mix with the external air, thereby avoiding the pollution of the natural gas. Then the natural gas enters the gas analyzer instrument shell 1 inside through the entering pipe 13. During the operation of the instrument, the gas analyzer instrument analyzes the natural gas and clearly displays various data and parameters such as the component ratio, pressure and temperature of the natural gas through the display 2.

[0042] When the parts inside the gas analyzer instrument shell 1 need to be repaired, the handle 5 is held and turned. Turning the handle 5 drives the rotating rod 4 to rotate, which in turn drives the circular plate 6 to rotate, and then drives the two push columns 7 to rotate, which in turn drives the opening plate 8 to slide. At this time, the two opening plates 8 slide to the side, thereby driving the sliding plate 9 to slide, which in turn drives the limiting frame 10 to slide and press the spring 1 11, so that the spring 1 11 can store elastic potential energy, thereby giving the sliding plate 9 a force in the opposite direction to engage the sliding plate 9 inside the gas analyzer instrument shell 1 for installation. Conversely, the cover plate 3 can be quickly removed without using tools to repair the parts inside the gas analyzer instrument shell 1, thereby improving the convenience of the device.

[0043] By holding the handle 23, the strip plate 22 is lifted and the rotating plate 21 is rotated, and then the strip plate 22 can drive the elastic member 26 to pop up through the elasticity of the elastic member 26 itself and the strip opening 25, so that the cable required for different detection can be clamped in the arc-shaped opening 24. Then, the strip plate 22 is pressed, and then the elastic member 26 is pushed to slide in the support frame 20 and is engaged in the strip opening 25 by using the self-resetting effect, thereby avoiding the overheating caused by the entanglement of the cable, thereby improving the test accuracy.

[0044] Finally, it should be pointed out that: the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent substitution, improvement, etc. made within the scope of the present application shall be included in the protection scope of the present application.
