DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Such as Figures 1 - 5As shown in the figure, the present utility model provides a technical solution: a high-pressure resistant automotive hose, including a hose body 1. The hose body 1 is woven with aramid fibers, making the hose body 1 have high toughness and tensile resistance. A connecting portion 2 is fixed at the front end of the hose body 1. A high-pressure resistant device 3 is provided on the hose body 1, and a clamping device 4 is fixed at the front end of the high-pressure resistant device 3.

[0023] The above-mentioned high-pressure resistant device 3 includes a high-strength steel wire mesh layer 31, stainless steel wires 32, a protective layer 33, a connecting groove 34, a fixing block 35, a spring 36 and a movable plate 37. The high-strength steel wire mesh layer 31 is fixedly installed on the inner wall of the hose body 1. The high-strength steel wire mesh layer 31 serves as a support to provide initial strength support. The stainless steel wires 32 are helically wound around the outer wall of the hose body 1. The helically wound stainless steel wires 32 enhance the overall compressive and wear-resistant capabilities. A protective layer 33 is fixed on the outer wall of the stainless steel wires 32. The protective layer 33 further protects the automotive hose on the outer wall of the stainless steel wires 32, preventing erosion, and at the same time balancing the external pressure to avoid the internal automotive hose being damaged due to uneven pressure. Connecting grooves 34 are formed on the outer wall of the protective layer 33. Fixing blocks 35 are fixedly connected to the inner walls of the connecting grooves 34. The pressure received by the fixing blocks 35 is balanced by the protective layer 33, enabling the internal automotive hose to be evenly pressured. A spring 36 is fixed to the side of the fixing block 35 away from the connecting groove 34. When the spring 36 is compressed to the maximum extent, it transmits pressure to the fixing block 35. One end of the spring 36 away from the fixing block 35 is fixed with a movable plate 37. When the movable plate 37 receives pressure, it compresses the spring 36. The movable plate 37 wraps around the outside of the protective layer 33, so that the protective layer 33 will not directly receive pressure. This high-pressure resistant device 3 uses different materials of reinforcing layers to be alternately stacked, and each layer of reinforcing layer is connected by an adhesive to ensure that there will be no slippage or separation between the layers in a high-pressure environment, ensuring that the automotive hose can be more high-pressure resistant during use and avoiding damage due to inability to withstand pressure.

[0024] The above clamping device 4 includes a protective sleeve 41, a first ejector rod 42, a second ejector rod 43 and a slider 44. The protective sleeve 41 is fixedly connected to the front end of the protective layer 33. The inner wall of the protective sleeve 41 is hinged with the first ejector rod 42. One end of the first ejector rod 42 away from the inner wall of the protective sleeve 41 is hinged with the second ejector rod 43. When the second ejector rod 43 rotates, it drives the first ejector rod 42 to rotate around the hinge point between the first ejector rod 42 and the inner wall of the protective sleeve 41. One end of the second ejector rod 43 away from the first ejector rod 42 is hinged with the slider 44. The sliding of the slider 44 drives the second ejector rod 43 to move. When the second ejector rod 43 moves, it rotates around the hinge point between the second ejector rod 43 and the slider 44. The inclined surface of the slider 44 is in contact with the movable plate 37. When the movable plate 37 is subjected to pressure, it moves towards the center of the automotive hose. When moving, it pushes the slider 44. The slider 44 slides along the inclined surface in the direction away from the protective layer 33. The bottom surface of the slider 44 is slidably connected to the outer wall of the protective sleeve 41. When the first ejector rod 42 and the second ejector rod 43 rotate, the hinge point between the first ejector rod 42 and the second ejector rod 43 moves towards the center of the protective sleeve 41, applying pressure to the component connected to the automotive hose and clamping it. This clamping device 4 can further stably install the automotive hose when it is under pressure, preventing the automotive hose from being excessively pressured in a certain direction and causing the automotive hose to fall off, resulting in accidents.

[0025] Working principle: A high-strength steel wire mesh layer 31 is used as a support inside the hose body 1 to provide initial strength support. The hose body 1 is woven with aramid fibers, making the hose body 1 have high toughness and tensile resistance. The outer layer of the hose body 1 is a helically wound stainless steel wire 32, enhancing the overall compressive and wear-resistant capabilities. The protective layer 33 further protects the automotive hose on the outer wall of the stainless steel wire 32, preventing erosion and at the same time balancing the external pressure. When the movable plate 37 is subjected to pressure, it compresses the spring 36. Only when the spring 36 is compressed to the maximum extent will it transmit pressure to the fixed block 35. The pressure received by the fixed block 35 is balanced by the protective layer 33, enabling the internal automotive hose to be evenly pressured.

[0026] When the movable plate 37 is subjected to pressure, it moves towards the center of the automotive hose. When moving, it pushes the slider 44. The slider 44 slides along the inclined surface in the direction away from the protective layer 33. The sliding of the slider 44 drives the second ejector rod 43 to move. When the second ejector rod 43 moves, it rotates around the hinge point between the second ejector rod 43 and the slider 44. When the second ejector rod 43 rotates, it drives the first ejector rod 42 to rotate around the hinge point between the first ejector rod 42 and the inner wall of the protective sleeve 41. When the first ejector rod 42 and the second ejector rod 43 rotate, the hinge point between the first ejector rod 42 and the second ejector rod 43 moves towards the center of the protective sleeve 41, applying pressure to the component connected to the automotive hose and clamping it.

[0027] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made thereto, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present utility model are all within the protection scope of the present utility model.
