The utility model has the advantages of being able to seal the flange end of the gas pipeline, and being able to block and open the gas transmission of the pipeline, so that when the pipeline needs to be connected later, it can be directly connected. When the device is actually used, due to the lack of a secondary reinforcement component for sealing, the structure needs to be frequently repaired and replaced during long-term use, increasing the input cost, and there are also potential safety hazards. At the same time, the device does not have a reinforcement component for plugging, so the long-term effectiveness of the plugging structure cannot be guaranteed, and it does not have a quick disassembly function. In view of the above problems, a gas pipeline plugging piece is provided here. Content of the Utility Model

Specific implementation manner

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figures 1-5 , an embodiment provided by the present utility model: a gas pipeline plugging member, including a gas pipeline 1, one end of the gas pipeline 1 is provided with a flange 2, one end of the flange 2 is provided with a plugging assembly 3, and a sealing and extrusion assembly 4 is embedded on the inner side surface of the flange 2 and the gas pipeline 1;

[0026] The plugging assembly 3 includes a plugging head 301, one end of the plugging head 301 penetrates into the interior of the gas pipeline 1, a pressing block 302 is installed at the other end of the plugging head 301, and a fastening ring 303 is sleeved on the outer surface of the pressing block 302. The plugging head 301 is inserted into the interior of the gas pipeline 1 to complete the plugging work. The fastening ring 303 is fixedly connected to the pressing block 302, which is convenient for continuously providing an anti-loosening effect for the plugging head 301 in the future.

[0027] Around the inner side of the outer surface of the fastening ring 303, a pressure rod 9 is installed. One end of the pressure rod 9 is sleeved with a protective outer cylinder 5. The pressure rod 9 passes through the inside of the protective outer cylinder 5 and is sleeved with a sleeve 10. A tension spring 11 is sleeved on the outer surface of the bottom end of the pressure rod 9. The pressure rod 9 is connected to the inside of the sleeve 10 through the tension spring 11 in a limited way. The fastening ring 303 drives the pressure rod 9 through the tension spring 11 and is firmly fixed inside the sleeve 10. When loosening occurs, the plugging head 301 generates a backward thrust. At this time, the fastening ring 303 is driven to move backward through the pressure block 302. The fastening ring 303 drives the pressure rod 9 to move backward inside the sleeve 10, thereby acting on the tension spring 11. At this time, the tension spring 11 generates a rebound force, which can stop the loosening of the plugging head 301 and make it return to its original position, ensuring the plugging timeliness.

[0028] One end of the sleeve 10 passes through one end of the protective outer cylinder 5. A positioning mechanism is arranged through the outer surface of the sleeve 10, and the sleeve 10 is fixedly connected to the protective outer cylinder 5 through the positioning mechanism. The sleeve 10 can be conveniently disassembled from the inside of the protective outer cylinder 5 by manually rotating the screw.

[0029] Two pressing plates 6 are sleeved on both sides of the outer surface of the protective outer cylinder 5. One end of the surface of the pressing plate 6 is fixedly installed with a mounting strip 7. Fastening bolts 8 are arranged through both sides of the mounting strips 7. The protective outer cylinder 5 is made of an elastic material. The protective outer cylinder 5 squeezes its elastic material through the fastening bolts 8 and the mounting strip 9, so as to strengthen the stability effect of the plugging head 301.

[0030] The sealing and pressing assembly 4 includes two arc-shaped plates 401. At both ends of one side of one arc-shaped plate 401, a compression spring 402 is installed. The compression spring 402 is in a compressed state. One end of the compression spring 402 is fixedly installed with a push block 403. An extrusion part 404 is installed between the push blocks 403. Both sides of the extrusion part 404 are in extrusion contact with the push block 403 through inclined surfaces. The extrusion part 404 is fixedly installed at the center of the top of the other arc-shaped plate 401. The sealing and pressing assembly 4 is used to strengthen the sealing effect of the plugging head 301. The compression spring 402 in the compressed state drives the push block 403 to extrude the extrusion part 404, so as to drive the extrusion part 404 to move inward by using the stress effect of the inclined surface force. The extrusion part 404 drives the arc-shaped plate 401 to extrude the plugging head 301, so as to ensure that the plugging head 301 will not be pushed and loosened during long-term use, and ensure the sealing effect of the structure.

[0031] Working principle: When in use, the plugging head 301 is inserted into one end of the gas pipeline 1, and then the flange 2 is used to seal and install one end of the gas pipeline 1. After the flange is sleeved on the gas pipeline 1, the sealing extrusion assembly 4 is used to enhance the sealing effect of the plugging head 301. The compression spring 402 in the compressed state drives the push block 403 to extrude the extrusion part 404, so as to drive the extrusion part 404 to move inward by the stress effect of the inclined surface force. The extrusion part 404 drives the arc plate 401 to extrude the plugging head 301, so as to ensure that the plugging head 301 will not be displaced or loosened during long-term use, and ensure the sealing effect of the structure. At the same time, the protective outer cylinder 5 is sleeved on the outer surface of the plugging head 301 to provide safety protection. At the same time, the protective outer cylinder 5 squeezes its elastic material through the fastening bolts 8 and the installation strip 9, so as to enhance the stability of the plugging head 301. The plugging head 301 is fixedly connected to the pressure rod 9 through the pressure block 302 and the fastening ring 303 to improve the plugging force. The fastening ring 303 drives the pressure rod 9 to be firmly fixed inside the sleeve 10 through the tension spring 11. When loosening occurs, the plugging head 301 generates a backward thrust. At this time, the fastening ring 303 is driven to move backward by the pressure block 302, and the fastening ring 303 drives the pressure rod 9 to move backward inside the sleeve 10, so as to act on the tension spring 11. At this time, the tension spring 11 generates a rebound force, which can stop the plugging head 301 from loosening and return it to its original position to ensure the plugging timeliness. The sleeve 10 can be conveniently disassembled from the inside of the protective outer cylinder 5 by manually rotating the screw.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
