Description

TECHNICAL FIELD

[0001] The utility model relates to hydraulic hose assembly technical field especially relates to a hydraulic hose assembly with protection structure. BACKGROUND

[0002] Hydraulic hose is also known as hydraulic oil pipe, hydraulic rubber pipe and high-pressure rubber pipe, which is usually used in mine hydraulic support and oil field exploitation. It is suitable for engineering construction, hoisting and transportation, metallurgical forging, mine equipment, ship, injection molding machinery and various machine tools, and is used in the hydraulic system of various industrial departments to play the role of connecting pipe.

[0003] During the use and installation of the hose, it is often difficult to avoid the contact and friction between the hose and the ground due to the complex and diverse working environment. For example, in some construction sites, the site conditions are simple and the space layout is compact, so it is difficult for workers to completely avoid the contact between the hose and the ground when laying or adjusting the position of the hose. However, the existing hydraulic hose often lacks effective outer protection measures in design. When the hose frequently rubs against the ground, the outer rubber or other materials can be easily worn out. As the degree of wear increases, the wall thickness of the hose gradually thins and the pressure resistance decreases, which not only easily causes leakage and other faults, but also may cause safety accidents. Moreover, frequent wear can greatly reduce the service life of the hose, increase the replacement cost and equipment downtime, and affect production efficiency and economic benefits. SUMMARY

[0012] The utility model discloses the beneficial effects of:

[0013] 1. Through the double action of the inner extrusion mechanism and the outer extrusion mechanism, the inner spring can automatically push the movable rod to the two ends of the pipe body without external force, so that the protective sleeve shields and protects the connection part of the pipe body and other components, preventing dust, impurities and the like from entering the connection part; the outer spring makes the limiting ring tightly adhere to the outer wall of the protective sleeve, ensuring that the protection strip does not come off from the mounting slot.

[0014] 2. The special H-shaped structure of the protection strip cooperates with the T-shaped mounting slot, which can effectively protect the pipe body and the protective sleeve, avoiding direct contact with the ground, thereby prolonging the service life of the pipe body.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] refer to Figures 1-4 A hydraulic hose assembly with a protective structure includes a hose body 1 and a protective sleeve 2. The protective sleeve 2 is fixedly installed on the outside of the hose body 1 by adhesive. The protective sleeve 2 has multiple mounting grooves 3, and a protective strip 4 is installed in each mounting groove 3. The protective sleeve 2 also has multiple movable grooves 8, and a movable rod 9 is installed in each movable groove 8 through an internal compression mechanism. The multiple movable rods 9 are connected to limit rings 7 through an external compression mechanism, and the ends of the multiple movable rods 9 are jointly installed with a protective sleeve 5.

[0023] The internal compression mechanism includes an internal spring 11 disposed within the movable groove 8. The two ends of the internal spring 11 are connected to the inner wall of the movable groove 8 and the outer wall of the movable rod 9, respectively. The elastic potential energy provided by the internal spring 11 automatically pushes the movable rod 9 towards both ends of the tube 1 without external force, thereby shielding and protecting the connection points between the tube 1 and other components, effectively preventing dust, impurities, etc., from entering the connection points and avoiding contamination or damage.

[0024] The external compression mechanism includes an external spring 10 sleeved on the outside of the movable rod 9. The two ends of the external spring 10 are connected to the outer wall of the protective sleeve 5 and the outer wall of the limiting ring 7, respectively. The elastic potential energy provided by the external spring 10 allows the limiting ring 7 to fit tightly against the outer wall of the protective sleeve 2 without external force, ensuring that the protective strip 4 will not detach from the mounting groove 3, thereby maintaining the stability of the protective structure.

[0025] The vertical cross-section of the mounting groove 3 is T-shaped, while the vertical cross-section of the protective strip 4 is I-shaped. This structural design allows the protective strip 4 to have a certain limiting effect within the mounting groove 3, ensuring that the protective strip 4 can only move laterally, facilitating disassembly and assembly, and ensuring that it will not easily fall off during operation.

[0026] The protective sleeve 5 is equipped with a sealing ring 12, which has a sealed sliding contact with the tube body 1. The sealing ring 12 can effectively prevent external impurities from entering the gap between the protective sleeve 5 and the tube body 1, ensuring that the connection part of the tube body 1 remains clean and sealed during operation.

[0027] Multiple actuating plates 6 are installed on the protective sleeve 5, each with a rubber protective pad. The actuating plates 6 are designed so that the operator can hold and move the protective sleeve 5 with their fingers, bringing it closer to or away from the protective sleeve 2, thereby facilitating the exposure of the connection between the tube body 1 and other components, and making it easier to perform installation, disassembly or maintenance operations.

[0028] In use, this utility model ensures the automatic reset and tight fit of the protective sleeve 5 through the dual action of the internal and external extrusion mechanisms, effectively preventing the intrusion of dust and impurities. The special structural design of the mounting groove 3 and the protective strip 4 gives the protective strip 4 a limiting function, making it easy to install and remove without easily falling off. Furthermore, the protective strip 4 effectively protects the pipe body 1 and the protective sleeve 2, preventing them from directly contacting the ground and extending the service life of the pipe body 1. The addition of the sealing ring 12 and the actuating plate 6 further enhances the sealing performance and ease of operation of the assembly, making it suitable for various hydraulic systems requiring high protection and easy maintenance.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
