Description

Technical Field

[0001] This utility model relates to the field of rubber and plastic pipe technology, specifically to a rubber and plastic pipe resistant to aging and deformation. Background Technology

[0002] Rubber and plastic pipes are commonly used materials in air conditioning ducts, industrial equipment, and building insulation due to their excellent thermal insulation properties and flexibility. However, traditional rubber and plastic pipes have the following significant drawbacks during installation:

[0003] Traditional rubber and plastic pipes are integral structures that require direct insertion into the pipe surface during installation. This is especially problematic at bends or irregularly shaped pipes, where excessive friction can easily cause the pipe wall to crack, affecting insulation performance and lifespan. Furthermore, traditional rubber and plastic pipes often rely on tape or cable ties for fixation, which are susceptible to displacement or detachment due to environmental vibrations or thermal expansion and contraction, further exacerbating damage or compromising the protection of pipe structures such as air conditioning ducts.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 and Figure 2 An anti-aging and deformation rubber-plastic pipe may include two inner covering layers 10, two sets of inner layer fixing units, two outer covering layers 30, two sets of outer layer fixing units, and a winding tape layer 50. When installed on the outside of a pipe structure such as an air conditioning duct, the two inner covering layers 10 are first symmetrically wrapped around the outside of the air conditioning duct. Then, the two sets of inner layer fixing units are respectively fitted onto the opposite ends of the two inner covering layers 10, and the two sets of inner layer fixing units are used to limit and fix the inner covering layers 10. The two sets of inner layer fixing units are connected by fasteners such as bolts or screws, allowing them to be detached. Next, the two outer covering layers 30 are symmetrically wrapped around the outer layers of the two inner covering layers 10, covering the gap between the two inner covering layers 10. Then, the two sets of outer layer fixing units are respectively fitted onto the opposite ends of the two outer covering layers 30, and the two sets of outer layer fixing units are used to limit and fix the outer covering layers 30. The two sets of outer fixing units are connected by fasteners such as bolts or screws, making them detachable. Finally, waterproof tape is wrapped around the outer layers of the two outer covering layers 30 to form a wrapping tape layer 50 that covers the outside of the two outer covering layers 30 and covers the gap between the two outer covering layers 30.

[0022] See Figure 3The inner fixing unit includes two symmetrical first fixing members 20. Each first fixing member 20 includes a first arc-shaped seat 21, two first connecting portions 22, an extension 23, and a first arc-shaped positioning section 24. The cross-section of the first arc-shaped seat 21 is set as a semi-circular arc, and the two first connecting portions 22 are respectively formed at both ends of the first arc-shaped seat 21. A connecting hole is formed on the first connecting portion 22 so that the two first fixing members 20 in the inner fixing unit can be connected by fasteners passing through the connecting hole. The extension 23 is formed at the center of the inner wall of the first arc-shaped seat 21, and the first arc-shaped positioning section 24 is formed at the end of the extension 23 facing away from the first arc-shaped seat 21, and the first arc-shaped positioning section 24 is coaxially distributed with the first arc-shaped seat 21. Two first slots 25 are formed between the first arc-shaped positioning section 24 and the extension section 23 and the inner wall of the first arc-shaped seat 21, which are positioned and engaged with the inner covering layer 10, so that the side end face of the inner covering layer 10 can be inserted into the first slots 25 and limited and pressed against the outside of the air conditioning pipe by the first fastener 20.

[0023] See Figure 4 The outer fixing unit includes two symmetrical second fixing members 40. Each second fixing member 40 includes a second arc-shaped seat 41, two second connecting portions 42, and a second arc-shaped positioning section 43. The cross-section of the second arc-shaped positioning section 43 is also set as a semi-circular arc, and the two second connecting portions 42 are respectively formed at both ends of the second arc-shaped seat 41. Connecting holes are also formed on the second connecting portions 42 so that fasteners can be used to connect the two second fixing members 40 in the outer fixing unit through the connecting holes. The second arc-shaped positioning section 43 is formed at the center of the inner wall of the second arc-shaped seat 41, and the second arc-shaped positioning section 43 and the second arc-shaped seat 41 are coaxially distributed. Two second slots 44 are formed between the end face of the second arc-shaped positioning section 43 and the inner wall of the second arc-shaped seat 41, which are positioned and engaged with the outer covering layer 30, so that the side end face of the outer covering layer 30 can be inserted into the second slots 44 and limited and pressed against the outside of the inner covering layer 10 by the second fixing members 40.

[0024] In this embodiment, both the inner covering layer 10 and the outer covering layer 30 are configured as rubber-plastic pads with closed-cell structures. They can be made of rubber (such as EPDM, NBR) and plastic (such as PVC, PE). The rubber provides elasticity, and the plastic provides strength and processability. During the production process, a foaming agent (such as AC foaming agent) is added to decompose it at high temperature, generate gas, and form bubbles. After extrusion molding, the bubbles are fixed after cooling to form a closed-cell structure.

[0025] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
