Description

Technical Field

[0001] This utility model relates to the field of hose technology, specifically to a high-toughness wear-resistant hose. Background Technology

[0002] Rubber hoses are flexible tubular materials used to transport media such as liquids, gases, or particulate matter, and have wide applications in industry, agriculture, construction, machinery manufacturing, and daily life. Depending on the environment and media used, rubber hoses can be manufactured from various materials, such as rubber, silicone, and polyurethane, and designed with different functional structures according to operating conditions. However, in actual use, ordinary rubber hoses, due to deficiencies in their materials or structural design, are easily affected by external wear and high-pressure extrusion, leading to a shortened service life and increased maintenance costs.

[0003] Utility model patent CN220060886U discloses a high-toughness wear-resistant silicone tube, including a silicone outer jacket, with wear-resistant rubber evenly distributed on the outer side of the silicone outer jacket, a support sleeve on the inner side of the silicone outer jacket, a silicone inner sleeve on the inner side of the support sleeve, and a pressure-resistant sleeve evenly distributed on the inner side of the silicone inner sleeve. Tensile strips are provided inside the multiple sets of pressure-resistant sleeves. This utility model, through the structural design and material of the wear-resistant rubber, effectively improves the wear resistance of the silicone tube and effectively prevents breakage caused by external wear. Through the structural design and material of the tensile strips and pressure-resistant sleeves, it effectively improves the pressure resistance and bending resistance of the silicone tube, effectively preventing deformation in the later stages. Through the structural design of the support sleeve, it effectively improves the support performance of the silicone tube, thereby improving the stability of the tubular structure and further enhancing its pressure resistance and bending resistance.

[0004] The existing technology described above improves wear resistance by incorporating multiple evenly distributed wear-resistant rubber layers on the outer wall of the silicone jacket. However, this design has certain limitations. Because the wear-resistant rubber does not completely cover the entire outer wall of the silicone jacket, the uncovered portion remains exposed to the abrasive environment during use, potentially leading to increased localized wear and affecting the overall service life. Therefore, we propose a high-toughness wear-resistant hose. By optimizing the design structure, we address the aforementioned technical problems, improving wear resistance while further enhancing the overall toughness, compressive strength, and service life of the hose. Utility Model Content

[0005] The purpose of this invention is to provide a high-toughness, wear-resistant rubber hose to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-toughness, wear-resistant hose includes an inner layer and an anti-pressure layer on the outer side of the inner layer. The anti-pressure layer is used to disperse internal pressure and prevent the hose from deforming under pressure. The anti-pressure layer includes multiple annular support blocks arranged at equal intervals. The annular support blocks uniformly transmit pressure through their even arrangement, avoiding stress concentration. The annular support blocks are sleeved on the outer wall of the inner layer. Multiple positioning grooves arranged in an annular array are formed on the outer side of the annular support blocks. The positioning grooves are used to fix the position of the support sleeves and ensure structural stability. Each positioning groove is provided with a support sleeve. A reinforcing layer is provided on the outer side of the anti-pressure layer to improve the hose's resistance to bending and torsion. An outer layer is provided on the outer side of the reinforcing layer to completely cover the outer wall of the hose and prevent external wear.

[0007] Preferably, the inner layer is made of silicone material and is used to directly contact the conveying medium. Its high temperature resistance and corrosion resistance are suitable for complex working conditions. The inner surface of the inner layer is smooth, which reduces the flow resistance of the medium and reduces friction loss.

[0008] Preferably, the annular support block is made of engineering plastic, which enhances the rigidity and fatigue resistance of the compression layer. The annular support block is bonded and fixed to the inner layer, which ensures that the compression layer and the inner layer are tightly fitted together and avoids displacement.

[0009] Preferably, the support sleeve is made of rubber material, which has both elasticity and cushioning properties. The outer wall of the support sleeve abuts against the inner wall of the reinforcing layer, and the outer wall contacts the reinforcing layer to maintain the shape of the tubing and assist in resisting pressure.

[0010] Preferably, the support sleeve is provided with a tensile strip, which is used to improve the longitudinal tensile strength of the hose and prevent excessive elongation. The tensile strip is made of carbon fiber material, which is lightweight and has excellent tensile properties.

[0011] Preferably, the inner layer, the annular support block, the support sleeve, and the reinforcing layer form an air cavity, which uses air elasticity to buffer pressure fluctuations, reduce vibration, and improve the heat insulation effect.

[0012] Preferably, the reinforcing layer is a metal mesh structure, which provides high-strength support to the tubing and prevents bending and deformation.

[0013] Preferably, the outer layer is a wear-resistant rubber layer made of polyurethane material. The polyurethane material improves the wear resistance and anti-aging properties of the outer layer. The outer surface of the outer layer is provided with wear-resistant particles with a height of 0.3-1 mm. The wear-resistant particles reduce the wear rate by reducing the contact area and enhance the anti-slip properties.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This high-toughness wear-resistant hose, through the design of a wear-resistant rubber layer and wear-resistant particles covering the entire outer surface, solves the problem of local wear of silicone outer shell caused by uneven distribution of wear-resistant rubber in the existing technology, significantly reduces the wear rate of the hose outer wall directly rubbing against the external environment, while improving anti-slip performance and extending the service life of the hose under complex working conditions.

[0015] 2. This high-toughness wear-resistant hose, through the equidistant arrangement of the annular support blocks in the pressure-resistant layer and their cooperation with the support sleeve, combined with the elastic buffering effect of the rubber material, achieves uniform distribution of internal pressure, effectively avoiding local deformation or rupture of the hose caused by stress concentration, and enhancing the hose's pressure resistance and bending resistance.

[0016] 3. This high-toughness wear-resistant hose adopts the synergistic effect of the metal mesh structure of the reinforcing layer and the carbon fiber tensile strips in the support sleeve, which significantly improves the longitudinal tensile strength and transverse torsional resistance, preventing the hose from excessively elongating or bending and breaking under high pressure or external force, and ensuring its structural integrity in working conditions.

[0020] Please see Figures 1-4 This utility model provides a technical solution: A high-toughness, wear-resistant rubber hose includes an inner layer 100 and an anti-pressure layer 200 on the outer side of the inner layer 100. The anti-pressure layer 200 is used to disperse internal pressure and prevent the hose from deforming under pressure. The anti-pressure layer 200 includes a plurality of annular support blocks 210 arranged at equal intervals. The annular support blocks 210 uniformly transmit pressure through their equal-distance arrangement, avoiding stress concentration. The annular support blocks 210 are sleeved on the outer wall of the inner layer 100. A plurality of positioning grooves 211 arranged in a ring array are formed on the outer side of the annular support blocks 210. The positioning grooves 211 are used to fix the position of a support sleeve 220. The positioning groove 211 is embedded and combined with the annular support block 210 through rubber vulcanization process to ensure structural stability. Each positioning groove 211 is provided with a support sleeve 220. The outer side of the pressure-resistant layer 200 is provided with a reinforcing layer 300. The reinforcing layer 300 is used to improve the bending and torsional resistance of the hose. The reinforcing layer 300 is wrapped around the pressure-resistant layer 200 by braiding and directly abuts against the outer wall of the support sleeve 220. The outer side of the reinforcing layer 300 is provided with an outer layer 400 to prevent external wear. The outer layer 400 is compounded with the reinforcing layer 300 through co-extrusion molding process to form a full-coverage protective structure.

[0021] In this embodiment, the inner layer 100 is made of silicone material. The inner layer 100 is used to directly contact the conveying medium. Its high temperature resistance and corrosion resistance are suitable for complex working conditions. The inner surface of the inner layer 100 is smooth, which reduces the flow resistance of the medium and reduces friction loss.

[0022] Specifically, the annular support block 210 is made of engineering plastic. The engineering plastic material enhances the rigidity and fatigue resistance of the compression layer 200. The annular support block 210 is bonded and fixed to the inner layer 100. The annular support block 210 is bonded to the outer wall of the inner layer 100 with a high-strength adhesive to form a compression skeleton, ensuring that the compression layer 200 and the inner layer 100 are tightly fitted and preventing displacement.

[0023] Furthermore, the support sleeve 220 is made of rubber material. The rubber support sleeve 220 has both elasticity and cushioning properties. The outer wall of the support sleeve 220 abuts against the inner wall of the reinforcing layer 300. The outer wall contacts the reinforcing layer 300 to maintain the shape of the tubing and assist in resisting pressure.

[0024] Furthermore, the support sleeve 220 is provided with a tensile strip 230, which is used to improve the longitudinal tensile strength of the hose and prevent excessive elongation. The tensile strip 230 is made of carbon fiber material, which is lightweight and has excellent tensile properties.

[0025] Furthermore, the inner layer 100, the annular support block 210, the support sleeve 220 and the reinforcing layer 300 form an air cavity 240. The air cavity 240 uses air elasticity to buffer pressure fluctuations, reduce vibration and improve the heat insulation effect.

[0026] Furthermore, the reinforcing layer 300 is a metal mesh structure, which provides high-strength support to the hose and prevents bending and deformation.

[0027] Furthermore, the outer layer 400 is a wear-resistant rubber layer made of polyurethane material. The polyurethane material enhances the wear resistance and anti-aging properties of the outer layer 400. The outer surface of the outer layer 400 is provided with wear-resistant particles 410. The height of the wear-resistant particles 410 is 0.3-1 mm. The wear-resistant particles 410 reduce the wear rate by reducing the contact area and enhance the anti-slip properties.

[0028] In this embodiment, the high-toughness wear-resistant hose first directly contacts the conveying medium through the inner layer 100. Its smooth inner surface reduces flow resistance, and its high-temperature and corrosion-resistant properties make it suitable for high-temperature or corrosive environments. The pressure-resistant layer 200 on the outside of the inner layer 100 is composed of multiple equally spaced annular support blocks 210. The annular support blocks 210 are reinforced with engineering plastic material and bonded to the inner layer 100 to evenly distribute the internal pressure. The positioning grooves 211 on the outside of the annular support blocks 210 are used to fix the rubber support sleeve 220. The carbon fiber tensile strips 230 are pre-embedded in the support sleeve 220. The longitudinal tensile strength is enhanced to prevent excessive elongation of the hose; the outer wall of the support sleeve 220 abuts against the metal mesh structure of the reinforcing layer 300, and the metal mesh structure provides anti-bending and anti-torsion support; the air cavity 240 formed by the inner layer 100, the annular support block 210, the support sleeve 220 and the reinforcing layer 300 buffers pressure fluctuations through air elasticity, reduces vibration and provides heat insulation; the outer layer 400 is made of polyurethane material and completely covers the outer wall of the reinforcing layer 300. The wear-resistant particles 410 on its surface reduce the wear rate and enhance anti-slip properties by reducing the contact area, ensuring the wear resistance and service life of the hose under complex working conditions.
