Description

Technical Field

[0001] This utility model relates to the field of hydraulic hose technology, and in particular to a hydraulic hose assembly. Background Technology

[0002] Hydraulic hose assemblies are two key components of hydraulic systems, each performing different functions. A hose crimping assembly is a connector used to connect the two ends of a high-pressure or low-pressure hose, ensuring a tight connection between the hose and the connector. A hydraulic hose assembly is a commonly used auxiliary device in hydraulic systems, consisting of a synthetic rubber inner hose resistant to liquid corrosion, a steel wire braided or wound reinforcement layer, and a high-performance synthetic rubber outer layer.

[0003] Existing hydraulic hose assemblies connect the fittings and hoses through a crimping process, providing sufficient connection strength to ensure that the hoses and fittings do not easily separate during hydraulic system operation. This guarantees system stability and reliability, effectively prevents leakage of hydraulic oil and other media, maintains stable system pressure, improves system efficiency, and reduces oil waste and environmental pollution caused by leakage.

[0004] However, in practical applications, existing hydraulic hose assemblies typically rely on simple crimping to connect the fittings to the hoses. When the hydraulic hose assembly is subjected to pressure and tension, the force tends to concentrate in localized areas of the crimping area, which may cause premature fatigue cracks or ruptures in these areas, or cause deformation or loosening of the fittings, thus hindering the extension of the service life of the hydraulic hose assembly.

[0005] Therefore, this application provides a hydraulic hose assembly to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies and propose a hydraulic hose assembly.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a hydraulic hose assembly, comprising:

[0008] Total cost of hydraulic hoses; A connector crimping assembly is provided, which is located at both ends of the hydraulic hose assembly. The connector crimping assembly includes an outer sleeve disposed at both ends of the hydraulic hose assembly. A rubber snap-fit ​​block is fixedly connected to the side of the hydraulic hose assembly near the outer sleeve, and a metal snap-fit ​​block is fixedly connected to the side of the outer sleeve near the rubber snap-fit ​​block. The hydraulic hose assembly and the outer sleeve are snapped together by the rubber snap-fit ​​block and the metal snap-fit ​​block. The sides of the rubber snap-fit ​​block and the metal snap-fit ​​block that are close to each other are both inclined structures.

[0009] Furthermore, a connector core is fixedly connected to one end of the outer casing near the inner side of the hydraulic hose assembly, and a sealing ring is fitted on the connector core near the inner side of the hydraulic hose assembly.

[0010] The beneficial effects of adopting the above-mentioned further solutions are: ensuring that the system maintains stable pressure, enabling hydraulic energy to be transmitted and converted efficiently, and ensuring the normal operation of the system.

[0011] Furthermore, an anti-slip coating is provided on one end of the connector core near the inner side of the hydraulic hose assembly.

[0012] The beneficial effect of adopting the above-mentioned further solution is that it can increase the tightness of the connection between the hose and the connector core, and reduce the relative displacement caused by vibration.

[0013] Furthermore, an elastic rubber pad is fixedly connected between the rubber clamping block and the metal clamping block of the hydraulic hose assembly.

[0014] The beneficial effects of adopting the above-mentioned further solutions are: preventing oil or other media from leaking from these gaps and forming multiple sealing defenses, which helps to further improve the sealing performance between the hose and the joint.

[0015] Furthermore, a strip-shaped snap-fit ​​block is fixedly connected to one end of the hydraulic hose assembly near the outer sleeve, and the hydraulic hose assembly is snapped to the outer sleeve through the strip-shaped snap-fit ​​block.

[0016] The beneficial effects of adopting the above-mentioned further solution are: preventing equal displacement between the hydraulic hose assembly and the outer sleeve, and improving the stability of the hydraulic hose assembly and the joint crimping assembly in use.

[0017] Furthermore, the length of the strip-shaped snap-fit ​​block is greater than the distance between the main body of the hydraulic hose and the outer sleeve.

[0018] The beneficial effect of adopting the above-mentioned further solution is that it enables the strip-shaped snap-fit ​​block to snap into the snap-fit ​​groove, providing positional and angular calibration between the hydraulic hose assembly and the outer sleeve, which facilitates subsequent crimping operations.

[0019] Furthermore, a friction coating is provided on the side of the metal snap block near the rubber snap block.

[0020] The beneficial effects of adopting the above-mentioned further solutions are: to make the connection between the hydraulic hose assembly and the outer sleeve more secure, to reduce the loosening of the connection caused by factors such as vibration and pressure changes, and to ensure the stability of the connection.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: By setting up a connector clamping assembly, the rubber clamping block and the metal clamping block interlock with each other, forming a mechanical interlocking method similar to a mortise and tenon structure. This unique connection method greatly enhances the connection strength between the hydraulic hose assembly and the outer sleeve, effectively preventing the hydraulic hose assembly from coming off the inside of the outer sleeve under pressure. The sides of the rubber clamping block and the metal clamping block that are close to each other are designed with bevels, which allows the force to be transmitted more evenly, avoiding stress concentration in local areas and reducing the risk of hose breakage due to stress concentration. It also reduces the possibility of joint damage due to uneven force, which has a positive effect on improving the service life of the hydraulic hose assembly. Attached Figure Description

[0024] 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.

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a hydraulic hose assembly, comprising: a hydraulic hose assembly body 1; like Figures 1-4As shown, the connector crimping assembly 2 is located at both ends of the hydraulic hose assembly 1. The connector crimping assembly 2 includes outer sleeves 21 at both ends of the hydraulic hose assembly 1. A rubber clamping block 22 is fixedly connected to the side of the hydraulic hose assembly 1 near the outer sleeve 21, and a metal clamping block 23 is fixedly connected to the side of the outer sleeve 21 near the rubber clamping block 22. The hydraulic hose assembly 1 and the outer sleeve 21 are connected by the rubber clamping block 22 and the metal clamping block 23. Both the rubber clamping block 22 and the metal clamping block 23 have beveled sides. By using a crimping tool, the outer sleeve 21 is crimped onto both ends of the hydraulic hose assembly 1, causing the rubber clamping block 22 and the metal clamping block 23 to engage. The interlocking blocks 23 interlock with each other, forming a mechanical interlocking structure similar to mortise and tenon, which greatly increases the connection strength between the hydraulic hose assembly 1 and the outer sleeve 21. This effectively prevents the hydraulic hose assembly 1 from coming out of the outer sleeve 21 under pressure. Furthermore, since the sides of the rubber interlocking blocks 22 and the metal interlocking blocks 23 that are close to each other are both inclined, the force transmission is more uniform, avoiding stress concentration in local areas. This solves the problem that when the hydraulic hose assembly is subjected to pressure and tension, the force is easily concentrated in the local area of ​​the crimping part, reducing the risk of hose rupture due to stress concentration or joint damage due to uneven force, and thus helping to improve the service life of the hydraulic hose assembly 1.

[0026] Furthermore, such as Figure 3 As shown, a connector core 26 is fixedly connected to one end of the outer sleeve 21 near the inner side of the hydraulic hose assembly 1. A sealing ring 27 is fitted on one end of the connector core 26 near the hydraulic hose assembly 1. By installing the sealing ring 27 between the hydraulic hose assembly 1 and the connector core 26, hydraulic oil can be effectively prevented from leaking out from the connection between the connector core 26 and the hydraulic hose assembly 1, ensuring that the system maintains stable pressure, enabling hydraulic energy to be transmitted and converted efficiently, and ensuring the normal operation of the system.

[0027] Furthermore, such as Figure 3 As shown, an anti-slip coating 28 is provided on one end of the connector core 26 near the inner side of the hydraulic hose assembly 1. By spraying the anti-slip coating 28 onto the connector core 26, the friction between the hydraulic hose assembly 1 and the connector core 26 can be significantly increased. This additional friction can make the connection between the hose and the connector core 26 tighter and reduce the relative displacement caused by vibration.

[0028] Furthermore, such as Figure 4As shown, an elastic rubber pad 24 is fixedly connected between the rubber clamping block 22 and the metal clamping block 23 in the hydraulic hose assembly 1. By installing the elastic rubber pad 24 between the rubber clamping block 22 and the metal clamping block 23, the space between the hydraulic hose assembly 1 and the outer sleeve 21 can be effectively filled, preventing oil or other media from leaking from these gaps. Together with the metal clamping block 23 and the rubber clamping block 22, it forms multiple sealing lines, which helps to further improve the sealing performance between the hose and the connector.

[0029] Furthermore, such as Figures 3-4 As shown, a strip-shaped snap-fit ​​block 25 is fixedly connected to one end of the hydraulic hose assembly 1 near the outer sleeve 21. The hydraulic hose assembly 1 is snapped into the outer sleeve 21 by the strip-shaped snap-fit ​​block 25. By opening a snap-fit ​​groove on the outer sleeve 21 that matches the strip-shaped snap-fit ​​block 25, when the outer sleeve 21 is pressed against the outside of the hydraulic hose assembly 1, the outer sleeve 21 pushes the snap-fit ​​groove to snap into the strip-shaped snap-fit ​​block 25. This allows the strip-shaped snap-fit ​​block 25 and the snap-fit ​​groove to provide a force perpendicular to the central axis for the connection between the hydraulic hose assembly 1 and the outer sleeve 21, preventing equal displacement between the hydraulic hose assembly 1 and the outer sleeve 21, and improving the stability of the hydraulic hose assembly 1 and the connector crimping assembly 2 in use.

[0030] Furthermore, such as Figure 4 As shown, the length of the strip-shaped snap-fit ​​block 25 is greater than the distance between the hydraulic hose main body 1 and the outer sleeve 21. By fitting the outer sleeve 21 onto the outside of the hydraulic hose main body 1, the strip-shaped snap-fit ​​block 25 can snap into the snap-fit ​​groove part because the length of the strip-shaped snap-fit ​​block 25 is greater than the distance between the hydraulic hose main body 1 and the outer sleeve 21. This provides positional and angular calibration between the hydraulic hose main body 1 and the outer sleeve 21, facilitating subsequent crimping operations.

[0031] Furthermore, such as Figure 5 As shown, a friction coating 29 is provided on the side of the metal snap-fit ​​block 23 near the rubber snap-fit ​​block 22. By spraying the friction coating 29 onto the metal snap-fit ​​block 23, the friction between the rubber snap-fit ​​block 22 and the metal snap-fit ​​block 23 can be increased, making the connection between the hydraulic hose assembly 1 and the outer sleeve 21 more stable, reducing the loosening of the connection caused by factors such as vibration and pressure changes, and ensuring the stability of the connection.

[0032] Working principle: such as Figures 1-5As shown, first, move the outer sleeve 21 to both ends of the hydraulic hose assembly 1. Insert the connector core 26 and sealing ring 27 into the inner side of the hydraulic hose assembly 1, and use the anti-slip coating 28 to provide friction to ensure a stable connection. Then, partially snap the strip-shaped snap-fit ​​block 25 into the snap-fit ​​groove on the outer sleeve 21. Since the length and angle of the strip-shaped snap-fit ​​block 25 are fixed, it is easy to calibrate the angle and position of the outer sleeve 21. Afterwards, use an external crimping machine to crimp the outer sleeve 21 onto the outside of the hydraulic hose assembly 1. At this time, the metal snap-fit ​​block 23 snaps between the rubber snap-fit ​​block 22 and the elastic rubber pad 24, so that the rubber snap-fit ​​block 22 and the metal snap-fit ​​block 23 interlock with each other, forming a mechanical interlocking structure similar to a tenon and mortise. This greatly increases the connection strength between the hydraulic hose assembly 1 and the outer sleeve 21. Furthermore, since the sides of both the rubber clamping block 22 and the metal clamping block 23 are inclined, the force transmission is more uniform, avoiding stress concentration in localized areas and improving the service life of the hydraulic hose assembly 1. Simultaneously, the strip-shaped clamping block 25 is fully engaged inside the clamping groove, providing a force perpendicular to the central axis for the connection between the hydraulic hose assembly 1 and the outer sleeve 21, preventing equal displacement between them. The friction coating 29 increases the friction between the rubber clamping block 22 and the metal clamping block 23, making the connection between the hydraulic hose assembly 1 and the outer sleeve 21 more stable.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
