Description

Technical Field

[0001] This utility model relates to the field of high-pressure hose technology, and in particular to a reinforcing rib structure for anti-twisting high-pressure hose. Background Technology

[0002] High-pressure hoses are flexible pipes composed of an inner rubber layer, a reinforcing layer, and an outer rubber layer. They can withstand high pressure and are mainly used in hydraulic and pneumatic systems to transport fluid media such as oil, water, and gas. They are widely used in engineering machinery, mining equipment, automobiles, and other fields. They can adapt to the movement requirements of equipment, achieve stable fluid transmission, and ensure the normal operation of various power systems or transmission systems.

[0003] A search revealed that the document with publication number "CN217177748U" states that "this utility model relates to the field of hose technology, and in particular to an ultra-high pressure hose, comprising a hose body, a collar provided on the outer side of the hose body, an inner hose provided on the inner side of the hose body; a reinforcing mesh provided on the outer side of the inner hose, an outer connecting ring provided at the connector of the inner hose, and a sealing bevel provided at the connector of the inner hose." Compared with existing hoses, this utility model, through its design, can improve the overall connection strength, economy, and practicality of the hose.

[0004] However, during the use of high-pressure hoses, due to the influence of internal pressure, the hoses will be subjected to strong expansion pressure from the inside out. At this time, relying on simple sheaths and other structures may not provide sufficient protection. Furthermore, during the use of high-pressure hoses, they may become twisted. When high-pressure hoses are twisted, they will cause severe deformation at the twisting point, leading to wear and tear and cracking of the internal structure, and in severe cases, direct breakage.

[0005] Therefore, we provide a torsion-resistant high-pressure hose reinforcing rib structure to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-pressure hose reinforcing structure for preventing torsion includes an inner hose tube, a connecting hose tube on the outer side of the inner hose tube, anti-torsion steel wires inside the connecting hose tubes, a protective tube on the outer side of the connecting hose tubes, and a hose reinforcing rib assembly on the outer side of the protective tube. The hose reinforcing rib assembly includes a circular support ring mounted on the surface of the protective tube, a cross-shaped anti-torsion core in the center of each circular support ring, a rectangular pad groove in the center of each cross-shaped anti-torsion core, and a shock-absorbing pad layer installed inside the rectangular pad groove.

[0007] As a further description of the above technical solution: The anti-torsion steel wire and the connecting hose are bonded together, and the anti-torsion steel wire is distributed at equal intervals.

[0008] As a further description of the above technical solution: The protective tube and the connecting tube are bonded together by adhesive, and the protective tube is made of wear-resistant nylon.

[0009] As a further description of the above technical solution: The circular support rings are evenly distributed on the surface of the protective tube, and the circular support rings are made of elastic stainless steel.

[0010] As a further description of the above technical solution: The cross-shaped anti-torsion core and the circular support ring are welded together. The cross-shaped anti-torsion core is made of elastic stainless steel. The cross-shaped anti-torsion cores are distributed in a crisscross pattern, and the cross-shaped anti-torsion core and the circular support ring form a cross-shaped support structure.

[0011] As a further description of the above technical solution: The shock-absorbing pad layer and the rectangular pad groove are connected by a slot. The shock-absorbing pad layer is made of silicone and has a honeycomb structure.

[0012] As a further description of the above technical solution: The outer side of the shock-absorbing pad is wrapped with a circular steel wire mesh, and the outer side of the circular steel wire mesh is wrapped with an outer rubber tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses anti-torsion steel wires and a protective tube. When needed, the connecting hose between the inner and outer tubes of the hose is enhanced with anti-torsion steel wires that are evenly distributed. When the inner tube of the hose is subjected to external torsional force, the anti-torsion steel wires can effectively disperse the internal stress and reduce the twisting phenomenon of the inner tube of the hose. The protective tube, with its wear-resistant nylon material, effectively reduces the wear and cracking of the internal structure when the high-pressure hose is twisted, thereby improving the service life.

[0014] 2. This utility model utilizes a hose reinforcing rib assembly. When needed, the circular support ring, thanks to the elasticity and strength of the elastic stainless steel material, can generate effective restraint when the inner tube of the hose deforms. When the internal pressure of the hose is too high, it can help disperse the pressure and improve overall stability. The cross-shaped anti-torsion core, using a cross-distributed elastic stainless steel structure, works in conjunction with the circular support ring to enhance the overall anti-torsion and anti-compression capabilities. It effectively suppresses deformation when the hose is bent or twisted under force and prevents structural collapse. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Please see Figure 1-4 As shown, this utility model provides a technical solution: a high-pressure hose reinforcing structure for preventing torsion, including an inner hose tube 1, a connecting hose 2 disposed on the outside of the inner hose tube 1, anti-torsion steel wires 3 disposed inside the connecting hose 2, a protective tube 4 disposed on the outside of the connecting hose 2, and a hose reinforcing rib assembly 5 disposed on the outside of the protective tube 4. The hose reinforcing rib assembly 5 includes a circular support ring 501 mounted on the surface of the protective tube 4, a cross anti-torsion core 502 disposed in the middle of the circular support ring 501, a rectangular pad groove 503 disposed in the middle of the cross anti-torsion core 502, and a shock-absorbing pad layer 504 installed inside the rectangular pad groove 503.

[0019] Furthermore, the anti-torsion steel wire 3 is bonded to the connecting hose 2, and the anti-torsion steel wire 3 is evenly distributed. When needed, the connecting hose 2 outside the inner tube 1 is enhanced with anti-torsion performance by the evenly distributed anti-torsion steel wire 3. When the inner tube 1 of the hose is subjected to external torsional force, the anti-torsion steel wire 3 can effectively disperse the internal stress and reduce the twisting phenomenon of the inner tube 1 of the hose.

[0020] Furthermore, the protective tube 4 and the connecting hose 2 are bonded together. The protective tube 4 is made of wear-resistant nylon. When needed, the protective tube 4 effectively reduces internal structural wear and cracking when the high-pressure hose is twisted due to its wear-resistant nylon material, thereby improving its service life.

[0021] Furthermore, the circular support rings 501 are evenly distributed on the surface of the protective tube 4. The circular support rings 501 are made of elastic stainless steel. When needed, the circular support rings 501 can generate an effective restraining force when the inner tube 1 of the hose deforms due to the elasticity and strength of the elastic stainless steel material. When the pressure inside the inner tube 1 of the hose is too high, the circular support rings 501 can help disperse the pressure and improve the overall stability.

[0022] Furthermore, the cross-shaped anti-torsion core 502 and the circular support ring 501 are welded together. The cross-shaped anti-torsion core 502 is made of elastic stainless steel and is distributed in a cross pattern. The cross-shaped anti-torsion core 502 and the circular support ring 501 form a cross-shaped support structure. When needed, the cross-shaped anti-torsion core 502 uses the cross-shaped elastic stainless steel structure, together with the circular support ring 501, to enhance the overall anti-torsion and anti-compression capabilities. This effectively suppresses deformation when the hose is bent or twisted under force and prevents structural collapse.

[0023] Furthermore, the shock-absorbing pad 504 and the rectangular groove 503 are connected by a slot. The shock-absorbing pad 504 is made of silicone and has a honeycomb structure. When needed, the shock-absorbing pad 504 filled inside the rectangular groove 503 formed by the circular support ring 501 and the cross anti-torsion core 502 can effectively absorb and buffer the vibration and impact energy generated by the inner tube 1 of the hose, and reduce fatigue damage caused by high-pressure fluid pulses or external mechanical vibrations.

[0024] Furthermore, the outer side of the shock-absorbing pad 504 is wrapped with a circular steel wire mesh 505, and the outer side of the circular steel wire mesh 505 is wrapped with an outer rubber tube 506. When needed, the circular steel wire mesh 505 will serve as an outer reinforcement structure to further enhance tensile and shear resistance, thereby providing protection from the outside.

[0025] Working principle: When needed, the inner tube 1 of the hose is first connected to the desired location. As the medium flows through the inner tube 1, it is subjected to outward pressure, which restrains the connecting hose 2 and the protective tube 4. The circular support ring 501 also provides protection. When the inner tube 1 twists, the direct contact surface of the inner tube 1 is resisted by the anti-twist steel wires 3 distributed inside the connecting hose 2. The circular support ring 501 on the surface of the protective tube 4 outside the inner tube 1, together with the cross anti-twist core 502, provides anti-twist protection from the outside. At the same time, the shock-absorbing pad 504 filled inside the rectangular groove 503 formed by the circular support ring 501 and the cross anti-twist core 502 provides shock absorption and impact resistance. Finally, the outermost outermost layer of the inner tube 1 is protected by the circular steel wire mesh 505 and the outer hose 506, improving overall safety. This completes the use of an anti-twist high-pressure hose reinforcing structure.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
