DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] In one embodiment, Figure 1-Figure 5 As shown, a conveying pipeline that is easy to dock includes a pipe body 101, the outer wall of the pipe body 101 is coated with an aerogel insulation layer 104, the outside of the aerogel insulation layer 104 is coated with a cold-resistant layer 105, the outside of the cold-resistant layer 105 is coated with an anti-corrosion and drag-reducing epoxy resin coating 106, a first flange 102 is provided on one end of the outer wall of the pipe body 101, a second flange 103 is provided on the other end of the outer wall of the pipe body 101, a fixing component 200 is provided on the side of the first flange 102, a positioning component 300 is provided on the side of the second flange 103, and sealing gaskets 107 are symmetrically provided at both ends of the pipe body 101.

[0024] In this embodiment, the pipe body 101 and the fixing component 200 and the positioning component 300 on the pipe body 101 are aligned, and the gas-liquid leakage is prevented by the close contact between the sealing gaskets 107 and the sealing gaskets 107. The outer layer of the pipe body 101 is provided with an aerogel insulation layer 104, a cold-resistant layer 105 and an anti-corrosion and drag-reducing epoxy resin coating 106, so that the pipe body 101 can be used for a long time.

[0025] In one embodiment, Figure 5 As shown, the fixing assembly 200 includes an insertion rod 201, and the insertion rod 201 is arranged in a circular array on the side of the first flange 102. A slide groove 203 is arranged on the side of the other end of the insertion rod 201. The slide groove 203 is arranged on the side of the insertion rod 201 close to the central axis of the tube body 101. One end of a spring 204 is fixedly arranged at the bottom of the slide groove 203, and the other end of the spring 204 is fixedly connected to a slider 202. A guiding inclined surface is arranged on the slider 202. The slider 202 is slidably arranged in the slide groove 203. A limiting sleeve 205 is fixedly arranged at the lower end of the slider 202, and the sum of the length of the limiting sleeve 205 and the height of the slider is less than the depth of the slide groove 203.

[0026] In this embodiment, when the insertion rod 201 is inserted into the positioning groove 301, the notch of the positioning groove 301 squeezes the guiding slope on the slider 302, causing the slider 202 to slide into the slide groove 203. The slider 202 squeezes the spring 204 to compress the spring 204. The limiting sleeve 205 at the bottom of the slider 202 ensures that the slider 202 does not slide out of the slide groove 203.

[0027] In one embodiment, Figure 4 As shown, the positioning assembly 300 includes positioning grooves 301, which are arranged in a circular array on the side of the second flange 103, and a fixing groove 302 is arranged on the side of the inner bottom of the positioning groove 301. The fixing groove 302 is arranged on the side of the positioning groove 301 close to the central axis of the tube body 101.

[0028] In this embodiment, when the top of the insertion rod 201 contacts the bottom of the positioning groove 301, the slider 202 loses its thrust, and under the elastic action of the spring 204, the slider 202 slides outward in the slide groove 203, so that the slider 202 slides into the fixing groove 302, docking and fixing the tube body 101 and the tube body 101.

[0029] The above embodiment discloses a delivery pipeline that is easy to dock, wherein the pipe body 101 and the insertion rod 201 on the pipe body 101 are aligned with the positioning groove 301, and the insertion rod 201 is inserted into the positioning groove 301. The notch of the positioning groove 301 squeezes the guiding inclined surface on the slider 302, so that the slider 202 slides into the slide groove 203. The slider 202 squeezes the spring 204 to compress the spring 204. The limiting sleeve 205 at the bottom of the slider 202 ensures that the slider 202 does not slide out of the slide groove 203. When the top of the insertion rod 201 contacts the positioning groove 301, the slider 202 is pressed against the guide inclined surface on the slider 302. When the slider 202 reaches the bottom of the tube body 101, the slider 202 loses its thrust. Under the elastic action of the spring 204, the slider 202 slides outward in the slide groove 203, so that the slider 202 slides into the fixing groove 302, and the tube body 101 is docked and fixed with the tube body 101. The close contact between the sealing gasket 107 and the sealing gasket 107 is used to prevent gas and liquid leakage. The outer layer of the tube body 101 is provided with an aerogel insulation layer 104, a cold-resistant layer 105 and an anti-corrosion and drag-reducing epoxy resin coating 106, so that the tube body 101 can be used for a long time. The conveying pipeline achieves the purpose of convenient docking pipelines.

Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
