Description

Technical Field

[0001] The present application relates to the technical field of pipe materials, and in particular to a compression-resistant and deformation-preventing composite pipe. Background Art

[0002] A composite pipe is a pipe made of a combination of two or more different materials. This design combines the advantages of different materials to meet specific usage requirements.

[0003] In the related art, reference can be made to the Chinese utility model patent with the authorization announcement number CN211203158U, which discloses a composite pipe. The composite pipe includes: an inner layer made of a first material; a core layer sleeved on the inner layer and made of a second material; and an outer layer sleeved on the core layer and made of a third material. The expansion coefficient of each of the first material and the third material is greater than or less than the expansion coefficient of the second material, and a first elastic buffer layer is provided between the inner layer and the core layer and / or a second elastic buffer layer is provided between the outer layer and the core layer.

[0004] However, in the actual use process of the above composite pipe, since the inner layer, the outer layer, and the filling material between the inner and outer layers are all elastic, the composite pipe is prone to deformation when affected by external pressure. Either the inside of the composite pipe is for passing a medium or it is filled with uniformly arranged pipelines. Therefore, the deformation of the composite pipe easily leads to the occlusion of the internal conveying channel of the composite pipe or the disorder of the pipelines located inside the composite pipe, thus having an adverse impact on the conduction performance of the composite pipe. Utility Model Content

[0005] In order to reduce the probability of deformation of the composite pipe after bearing external pressure, the present application provides a compression-resistant and deformation-preventing composite pipe.

[0006] A compression-resistant and deformation-preventing composite pipe provided by the present application adopts the following technical solutions:

[0007] A compression-resistant and deformation-preventing composite pipe includes an outer pipe and an inner pipe. The inner pipe is disposed inside the outer pipe, and a filling mechanism for filling and supporting the gap between the outer pipe and the inner pipe is provided between the outer pipe and the inner pipe. The filling mechanism includes:

[0008] Filling rings, the filling rings are sleeved on the inner pipe and abutted against the inner side wall of the outer pipe. A plurality of the filling rings are provided, and the plurality of filling rings are uniformly distributed along the axial direction of the inner pipe;

[0009] Filling ribs, the filling ribs are disposed on adjacent two filling rings and located between the adjacent two filling rings. A plurality of the filling ribs are provided, and the plurality of filling ribs are uniformly distributed along the outer side wall of the inner pipe;

[0010] A positioning assembly is arranged on the outer tube and is used to fix the position between the outer tube and the filling ring.

[0011] By adopting the above technical solution, a plurality of filling rings are sleeved on the inner tube, and a plurality of filling ribs are arranged between the filling rings. The filling rings and the filling ribs cooperate to fill the gap between the inner tube and the outer tube, and the filling rings and the filling ribs cooperate to support the outer tube. The filling rings support the radial deformation of the outer tube, and the filling ribs support the axial deformation of the outer tube, thereby reducing the probability of deformation after being subjected to external pressure, thereby protecting the inner tube to perform normal conduction work and improving the overall service life of the composite tube.

[0012] Optionally, the positioning component includes:

[0013] A first positioning clamping plate, the first positioning clamping plate is arranged on the inner side wall of the outer tube, and the first positioning clamping plates are arranged in a plurality of groups of two, and the two first positioning clamping plates in a group are respectively located on both sides of the filling ring and in conflict with the filling ring;

[0014] The second positioning clamping plate is arranged on the inner wall of the outer tube, and the second positioning clamping plates are arranged in a plurality of groups of two. The two second positioning clamping plates in a group are respectively located on both sides of the filling rib and are in conflict with the filling rib.

[0015] By adopting the above technical solution, two first positioning clamps are arranged on both sides of the filling ring, and two second positioning clamps are arranged on both sides of the filling rib. The two first positioning clamps cooperate with the clamping column filling ring to fix the axial position of the filling ring on the inner tube, thereby reducing the probability of the filling ring being offset or bent when subjected to external force, and while positioning the filling ring, the overall compressive resistance of the composite pipe is improved; the two second positioning clamps cooperate to clamp the filling rib, thereby fixing the position between the filling rib and the filling ring, so that the filling rib can always press against the two filling rings, ensuring the fixing effect of the filling rib on the two filling rings.

[0016] Optionally, a buffer layer is provided on the inner side wall of the outer tube between the two first positioning clamps and on the inner side wall of the outer tube between the two second positioning clamps, and the buffer layer contacts the end of the filling ring.

[0017] By adopting the above technical solution, a buffer layer is installed between the two first positioning clamps and the two second positioning clamps. When the outer tube is deformed by external pressure, the buffer layer buffers the deformation displacement of the outer tube, thereby reducing the pressure transmitted from the outer tube to the inner tube and improving the overall compressive resistance of the composite tube.

[0018] Optionally, an arc-shaped guide surface is provided on an end surface of the filling ring that contacts the buffer layer.

[0019] By adopting the above technical solution, an arc-shaped guiding surface is provided on one end surface of the filling ring in contact with the buffer cushion layer, thereby increasing the contact area between the buffer cushion layer and the filling ring, and thus reducing the pressure transmitted by the buffer cushion layer to the filling ring.

[0020] Optionally, deformation soft blocks are provided on the outer side wall of the outer tube. There are a plurality of the deformation soft blocks, and the plurality of deformation soft blocks are evenly distributed on the outer side wall of the outer tube, and deformation grooves are provided between the plurality of deformation soft blocks.

[0021] By adopting the above technical solution, a number of deformation soft blocks are installed on the outer side wall of the outer tube. After the deformation soft blocks receive an external impact, they first deform through the deformation grooves, thereby reducing part of the pressure received by the outer tube and improving the compressive performance of the outer tube.

[0022] Optionally, a fluorescent dye is evenly coated on the surface of the deformation soft block.

[0023] By adopting the above technical solution, a fluorescent dye is evenly coated on the surface of the deformation soft block, so that in a dim environment, people or animals can distinguish the position of the composite tube, thereby reducing the probability that people or animals accidentally step on the composite tube and cause it to deform.

[0024] Optionally, the inner tube and the filling rib strips are integrally formed, and the outer tube, the first positioning clamp plate and the second positioning clamp plate are all integrally formed.

[0025] By adopting the above technical solution, the inner tube and the filling rib strips are integrally formed, and the outer tube, the first positioning clamp plate and the second positioning clamp plate are all integrally formed, thereby improving the overall structural strength of the inner tube and the outer tube and improving the compressive performance of the composite tube.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. By sleeving a number of filling rings on the inner tube and arranging a number of filling rib strips between the filling rings, the filling rings and the filling rib strips cooperate to fill the gap between the inner tube and the outer tube, and the filling rings and the filling rib strips cooperate to support the outer tube. The filling rings support the radial deformation of the outer tube, and the filling rib strips support the axial deformation of the outer tube, thereby reducing the probability of deformation after bearing external pressure, protecting the inner tube to conduct normally, and improving the overall service life of the composite tube;

[0028] 2. By installing a buffer cushion layer between the two first positioning clamp plates and the two second positioning clamp plates, when the outer tube deforms under the action of external pressure, the buffer cushion layer buffers the deformation displacement of the outer tube, thereby reducing the pressure transmitted by the outer tube to the inner tube and improving the overall compressive performance of the composite tube.

[0029] 3. By integrally forming the inner tube and the filling rib, and integrally forming the outer tube with both the first positioning clamp and the second positioning clamp, the overall structural strength of the inner tube and the outer tube is improved, and the compressive performance of the composite tube is enhanced.

The inner tube 12 is inserted into the inner part of the outer tube 11, and a filling mechanism 2 for filling and supporting the gap between the outer tube 11 and the inner tube 12 is arranged between the outer tube 11 and the inner tube 12.

[0037] Referring to Figure 1 and Figure 2 , the filling mechanism 2 includes a filling ring 21 and a filling rib 22. A plurality of filling rings 21 are arranged, and the plurality of filling rings 21 are uniformly sleeved on the outer side wall of the inner tube 12 along the axial direction of the inner tube 12. The filling rib 22 is fixedly installed on the outer side wall of the inner tube 12, and the filling rib 22 is integrally formed with the inner tube 12. A plurality of filling ribs 22 are arranged, and the filling ribs 22 are located between two adjacent filling rings 21. Both ends of the filling rib 22 respectively abut against the opposite side walls of two adjacent filling rings 21. The plurality of filling ribs 22 are uniformly arranged along the outer side wall of the inner tube 12.

[0038] Referring to Figure 1 and Figure 3, the filling mechanism 2 further includes a positioning component 23. The positioning component 23 is arranged on the outer tube 11 and is used to fix the position between the outer tube 11 and the filling ring 21.

Both the first positioning clamping plate 24 and the second positioning clamping plate 25 are integrally formed with the outer tube 11 and are located on the inner side wall of the outer tube 11.

[0039] Referring to Figure 2 and Figure 3 , several groups of the first positioning clamping plates 24 are arranged in groups of two. The two first positioning clamping plates 24 in a group are respectively located on both sides of the filling ring 21 and are in contact with the filling ring 21. A buffer cushion layer 13 is arranged on the inner side wall of the outer tube 11 between the two first positioning clamping plates 24. The buffer cushion layer 13 is in contact with the end of the filling ring 21. An arc-shaped guiding surface 14 is provided on the end surface of the end of the filling ring 21 in contact with the buffer cushion layer 13.

[0043] A number of packing rings 21 are sleeved on the inner tube 12, and a number of packing ribs 22 are arranged between the packing rings 21.
