Specific embodiments

[0020] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0021] As Figure 1 - Figure 2 shown, a gas filling joint convenient for docking includes a filling joint pipe 1, a connecting pipe 2 and a sealing component 4. Both ends of the filling joint pipe 1 are connected with a connecting pipe 2, and a sealing component 4 is arranged at the connection between the filling joint pipe 1 and the connecting pipe 2. Connecting threads 3 are arranged on the inner walls at both ends of the filling joint pipe 1 and on the outer wall of the connecting pipe 2 near one end of the filling joint pipe 1, and the filling joint pipe 1 and the connecting pipe 2 are screwed together; a reinforcement component 5 is installed outside the filling joint pipe 1;

[0022] The specific operation is as follows. Both ends of the filling joint pipe 1 can be screwed with the connecting pipe 2 respectively, so as to facilitate docking, without using flange or bolt connection, and the sealing component 4 at the connection between the filling joint pipe 1 and the connecting pipe 2 can enhance the connection sealing performance.

[0023] As Figure 2 - Figure 3 shown, the sealing component 4 includes a fixed inner pipe 401, an airbag layer 402, a clamping inner pipe 404 and a sealing layer 406. Fixed inner pipes 401 are integrally fixed on the inner sides at both ends of the filling joint pipe 1, and an airbag layer 402 is adhesively arranged on the inner side of the fixed inner pipe 401. A clamping inner pipe 404 is integrally fixed on the inner side of one end of the connecting pipe 2, and the cross-sections of the fixed inner pipe 401 and the clamping inner pipe 404 are both in an "L" shape. A sealing layer 406 is adhesively attached to the outer side of the fixed inner pipe 401 close to the inner wall of the connecting pipe 2. The airbag layer 402 is in an annular structure, and a rubber layer is arranged on the inner surface of the airbag layer 402, and the rubber layer on the inner surface of the airbag layer 402 is in mutual contact with the clamping inner pipe 404; the sealing component 4 includes an inflation nozzle 403 and an air extraction nozzle 405, and both the inflation nozzle 403 and the air extraction nozzle 405 penetrate through the pipe wall of the filling joint pipe 1. One side of the airbag layer 402 is connected with the inflation nozzle 403, and one side of the connection between the connecting pipe 2 and the fixed inner pipe 401 is connected with the air extraction nozzle 405;

[0024] The specific operation is as follows. After the docking and assembly between the filling joint pipe 1 and the connecting pipe 2, both ends of the connecting pipe 2 can be clamped between the fixed inner pipe 401 and the connecting pipe 2. At this time, the sealing layer 406 can play a sealing role. Through the air extraction nozzle 405, it is convenient to extract air between the fixed inner pipe 401 and the connecting pipe 2 to form a negative pressure between them, thereby tightly connecting to prevent loosening. The airbag layer 402 provided between the clamping inner pipe 404 and the fixed inner pipe 401 can further enhance the sealing performance of the connection, and through the inflation nozzle 403, it is convenient to inflate the airbag layer 402 to make it fully expand, so as to fully seal the connection.

[0025] As Figure 1 - Figure 2 shown, the reinforcement assembly 5 includes a fixed outer ring 501, a fixed rod 502 and a cross plate 503. The fixed outer ring 501 is fixedly connected to the filling joint pipe 1, and a fixed rod 502 is connected above the fixed outer ring 501, and a cross plate 503 is fixed above the fixed rod 502; the reinforcement assembly 5 further includes a sliding block 504 and a connecting rod 505. The lower side of the cross plate 503 is slidably connected with the sliding block 504 through a T-shaped groove and a T-shaped block, and a connecting rod 505 is fixed below the sliding block 504; the reinforcement assembly 5 further includes a clamping upper ring 506, a connecting bolt 507, a clamping lower ring 508 and a rubber pad 509. The connecting rod 505 is fixed with a clamping upper ring 506 below, and the connecting bolt 507 penetrates through the convex plates on both sides of the clamping upper ring 506. The lower side of the connecting bolt 507 is connected with a clamping lower ring 508, and rubber pads 509 are bonded to the inner sides of the clamping upper ring 506 and the clamping lower ring 508;

[0026] The specific operation is as follows. The upper cross plate 503 can play a certain protective role. Through the sliding connection between the sliding block 504 and the cross plate 503, it is convenient to adjust the positions of the clamping upper ring 506 and the clamping lower ring 508, so that the clamping upper ring 506 and the clamping lower ring 508 can be located outside the connection at both ends of the filling joint pipe 1. By tightening the connecting bolt 507, it is convenient to tighten the upper and lower clamping upper rings 506 and clamping lower rings 508, so that the clamping upper ring 506 and the clamping lower ring 508 clamp the connection between the filling joint pipe 1 and the connecting pipe 2, and can perform secondary positioning and fastening after installation, enhancing the connection strength at the connection between the two.

[0027] In summary, as Figure 1 - Figure 3As shown, for the gas filling connector with convenient docking, during use, first, both ends of the filling connector pipe 1 can be threadedly connected to the connecting pipe 2 respectively. This method is convenient for docking and does not require the use of flanges or bolt connections. After the filling connector pipe 1 and the connecting pipe 2 are assembled by docking, both ends of the connecting pipe 2 can be clamped between the fixed inner pipe 401 and the connecting pipe 2. At this time, the sealing layer 406 can play a sealing role. It is also possible to evacuate the space between the fixed inner pipe 401 and the connecting pipe 2 through the air extraction nozzle 405 to create a negative pressure between them, thereby tightly connecting to prevent loosening. Then, the airbag layer 402 provided between the clamping inner pipe 404 and the fixed inner pipe 401 can further enhance the sealing performance of the connection, and the airbag layer 402 can be inflated through the inflation nozzle 403 to make it fully expand, so as to fully seal the connection point.

[0028] Then, the positions of the clamping upper ring 506 and the clamping lower ring 508 can be adjusted by the sliding connection between the sliding block 504 and the cross plate 503, so that the clamping upper ring 506 and the clamping lower ring 508 can be located outside the connection points at both ends of the filling connector pipe 1. Then, by tightening the connecting bolts 507, the upper and lower clamping upper rings 506 and clamping lower rings 508 are tightened, and locked with nuts, so that the clamping upper ring 506 and the clamping lower ring 508 clamp the connection point between the filling connector pipe 1 and the connecting pipe 2, thereby enabling secondary positioning and fastening after installation, enhancing the connection strength at the connection between the two. In this way, the use process of the gas filling connector with convenient docking is completed.
