More specifically, the gas pipeline to be detected is inserted into the socket component 1, and the socket component 1 is locked by the locking component 2, so that the socket component 1 is stably installed on the surface of the gas pipeline, wherein the gas monitor body 4 is placed inside the protective component 3, and the gas monitor body 4 can be protected by the protective component 3. At the same time, the protective component 3 can be rotated to facilitate the adjustment of the direction of the gas monitor body 4 according to the direction of the gas pipeline. The surface of the protective component 3 is cleaned by the self-cleaning component 6 to prevent dust from hindering the gas monitor body 4 from detecting gas. The positioning component 7 can release the limit on the gas monitor body 4, and the gas monitor body 4 can be taken out from the inside of the protective component 3 to complete the quick disassembly.

[0029] The socket assembly 1 includes a first clamp ring 101 and a second clamp ring 102, the end of the first clamp ring 101 is fixedly connected with a concave seat 104, the end of the second clamp ring 102 is fixedly connected with a connector 103, and the connector 103 and the concave seat 104 are rotatably connected. It should be noted that the gas pipeline to be tested is clamped between the first clamp ring 101 and the second clamp ring 102, and the first clamp ring 101 and the second clamp ring 102 can be rotated around the position of the connector 103 and the concave seat 104, so that the first clamp ring 101 and the second clamp ring 102 are closely attached to the surface of the gas pipeline. It is best to roll up the ends of the first clamp ring 101 and the second clamp ring 102 through the locking assembly 2, so that the first clamp ring 101 and the second clamp ring 102 can clamp and fix the gas pipeline.

[0030] The locking assembly 2 includes a mounting seat 201, and the mounting seat 201 is fixedly connected to one end of the second retaining ring 102 away from the connecting head 103, the inner wall of the mounting seat 201 is rotatably connected to the worm 202, the end of the worm 202 is fixedly connected to the first knob 203, the surface of the mounting seat 201 is rotatably connected to the winding shaft 204, the surface of the winding shaft 204 is fixedly sleeved with a worm gear 205, and the worm gear 205 is meshed with the worm 202, and the end of the first retaining ring 101 away from the concave seat 104 is fixedly connected to a tightening belt 206, and the tightening belt 206 is wound on the surface of the winding shaft 204. More specifically, the tightening belt 206 is pulled to the surface of the winding shaft 204 and simply wound, and then the first knob 203 is turned to drive the worm 202 to rotate, and the worm 202 drives the worm wheel 205 meshing with it to rotate, thereby driving the winding shaft 204 to rotate, and further tightening the tightening belt 206, so that the first clamping ring 101 and the second clamping ring 102 are close to each other and squeeze the gas pipeline, so that the socket assembly 1 is stably installed on the surface of the gas pipeline, and the worm 202 and the worm wheel 205 have a self-locking effect, so that the tightening belt 206 cannot be sent.

[0031] The first clamping ring 101 and the second clamping ring 102 are fixedly connected to the opposite side with a toothed anti-skid strip 9, and the toothed anti-skid strip 9 is made of rubber. It should be noted that by adding the toothed anti-skid strip 9 made of rubber, the friction with the surface of the gas pipeline can be increased, so that the sleeve assembly 1 is sleeved on the pipeline more stably and not easy to slide.

[0032] The protection assembly 3 includes a damping shaft 301, and the damping shaft 301 is rotatably connected to the surface of the second clamping ring 102, the front end of the damping shaft 301 is rotatably connected to a protection shell 302, and the gas monitor body 4 is movably plugged into the inner wall of the protection shell 302, the top of the protection shell 302 is hinged with a top cover 303, the front of the protection shell 302 is provided with an air inlet slot 304, and the air inlet slot 304 is arranged in alignment with the detection hole 5.

[0033] The positioning assembly 7 includes a double-headed screw 701, and the double-headed screw 701 is rotatably connected to the protective shell 302. The end of the double-headed screw 701 is fixedly connected to the second knob 702. The surface of the double-headed screw 701 is threadedly connected to a connecting rod 703. The top of the connecting rod 703 is fixedly connected to a clamping plate 706. The side of the clamping plate 706 close to the gas monitor body 4 is fixedly connected to a pressure pad 704. The inner wall of the protective shell 302 is provided with a limiting groove 705, and the inner wall of the limiting groove 705 is slidably connected to the surface of the connecting rod 703. It should be noted that by rotating the second knob 702, the double-headed screw 701 can be driven to rotate, and under the action of the thread, the connecting rod 703 will be driven to slide along the inner wall of the limiting groove 705, thereby driving the clamping plate 706 to move, so that the pressure pad 704 no longer touches the surface of the gas monitor body 4, and the limit on the gas monitor body 4 can be released. After opening the top cover 303, the gas monitor body 4 can be quickly disassembled by pulling it upwards.

[0034] The self-cleaning assembly 6 includes a motor 601, and the motor 601 is fixedly mounted on the front of the protective shell 302, the output end of the motor 601 is fixedly connected with a screw rod 602, the surface of the screw rod 602 is threadedly connected with a mounting rod 604, the front of the protective shell 302 is fixedly connected with a slide column 603, and the slide column 603 is slidably connected to the mounting rod 604, the surface of the mounting rod 604 is slidably connected with a brush 605, and the brush 605 is slidably connected to the surface of the air inlet slot 304. More specifically, the motor 601 is operated to drive the screw rod 602 to rotate, and under the action of the surface thread, the mounting rod 604 will be driven to slide along the surface of the slide column 603, and the mounting rod 604 will drive the brush 605 to slide horizontally, and the surface of the air inlet slot 304 is cleaned by the brush 605 to avoid dust on the surface of the air inlet slot 304 from being blocked, thereby ensuring the ventilation effect at the air inlet slot 304, so that the gas that may leak can smoothly enter the air inlet slot 304.

[0035] The surface of the reel 204 is fixedly sleeved with an anti-skid ring 8. It should be noted that by providing the anti-skid ring 8, the friction force with the surface of the tightening belt 206 is increased, so that the tightening belt 206 wound on the surface of the reel 204 is not easy to slip.

[0036] In summary: the gas pipeline to be detected is inserted into the socket component 1, and the socket component 1 is locked by the locking component 2, so that the socket component 1 is stably installed on the surface of the gas pipeline, wherein the gas monitor body 4 is placed inside the protective component 3, and the gas monitor body 4 can be protected by the protective component 3, and the protective component 3 can be rotated at the same time, so as to facilitate the adjustment of the direction of the gas monitor body 4 according to the direction of the gas pipeline, and the surface of the protective component 3 is cleaned by the self-cleaning component 6 to prevent dust from hindering the gas monitor body 4 from detecting gas.

In use, the effect of effective dust protection for the gas detector is achieved, the detection position can be automatically cleaned to prevent dust and impurities from adversely affecting the monitor, and the monitor can be quickly disassembled, making maintenance or replacement more convenient.
