[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following examples are intended to illustrate the present invention and are not intended to limit the scope of protection of the present invention. The conditions in the examples may be further adjusted according to specific conditions. Simple improvements to the method of the present invention based on the concept of the present invention fall within the scope of protection claimed by the present invention.

[0021] See also Figure 1-3 The utility model provides a hose assembly that is convenient for connection, including a hose body 1, one end of the hose body 1 is fixedly connected to a No. 1 flange 3, and the other end of the hose body 1 is fixedly connected to a No. 2 flange 4; a connecting component, the connecting component is used for connecting and fixing the two hose bodies 1, the connecting component is connected to the hose body 1, the connecting component includes four connecting pieces 6 fixed to the outside of the No. 1 flange 3 in an annular shape, four cavities adapted to the connecting pieces 6 are opened inside one side of the No. 2 flange 4, the connecting piece 6 is an arc-shaped structure as a whole, and a deformation cavity 7 is opened inside the connecting piece 6, the surface of the connecting piece 6 is provided with three arc-shaped protrusions, and the inner wall of the deformation cavity 7 is provided with a deformation groove adapted thereto;

[0022] When the two hose bodies 1 need to be connected, first ensure that the No. 1 flange 3 and the No. 2 flange 4 are aligned with each other. At this time, the four connectors 6 on the outside of the No. 1 flange 3 will correspond to the four holes opened inside the No. 2 flange 4. Since the connector 6 is designed as an arc structure and has a deformation cavity 7 inside, this makes the connector 6 have a certain elastic deformation ability. When the connector 6 is inserted into the cavity of the No. 2 flange 4, the arc-shaped protrusion will deform along the path of the deformation groove, thereby smoothly entering the cavity. As the connector 6 is fully inserted, the deformation cavity 7 and the deformation groove on its inner wall will gradually return to their original state. At this time, the arc-shaped protrusion will be firmly engaged in the deformation groove, achieving a stable connection between the two hose bodies 1. The connection assembly design of the utility model is simple and efficient. The connection can be completed without the use of additional auxiliary tools, which greatly improves work efficiency. The arc-shaped design of the connector 6 and the setting of the deformation cavity 7 enable the connector 6 to deform during the insertion process, thereby increasing the tightness and stability of the connection. Once the connection is complete, the arcuate protrusion will be securely engaged within the deformation groove, effectively preventing the connection from loosening or falling off. The arcuate protrusion and deformation groove design of the connector 6 not only increases the stability of the connection, but also enhances the structural strength of the entire hose assembly. This allows the hose assembly to maintain stable performance when subjected to high pressure or external forces. Due to its convenient connection method and stable connection performance, the hose assembly of the present invention is suitable for various applications requiring hose connection, such as hydraulic systems and pneumatic systems. The design of the connection component makes the connection process simple and secure, thereby reducing the maintenance cost and time caused by loose or falling connections.

[0023] The hose body 1 is fitted with a threaded ring 5 made of stainless steel and wrapped with a braid 2 made of polytetrafluoroethylene. The design of the threaded ring 5 and braid 2 on the hose body 1 primarily enhances the overall performance and durability of the hose assembly. The threaded ring 5 provides an additional layer of protection, its stainless steel material providing excellent corrosion resistance and mechanical strength. The braid 2 tightly wraps around the threaded ring 5, its polytetrafluoroethylene (PTFE) material imparting excellent chemical and high-temperature resistance. In practical applications, the threaded ring 5 and braid 2 play a vital role when the hose assembly is in operation, whether conveying high-pressure media or facing complex external environments. The threaded ring 5, with its robust structure and stainless steel material properties, effectively resists external pressure and abrasion, protecting the hose body 1 from damage. At the same time, the polytetrafluoroethylene material of the braided layer 2 enables it to resist the erosion of various chemicals, as well as deformation and aging in high temperature environments, further extending the service life of the hose. The addition of the threaded ring 5 and the braided layer 2 significantly enhances the structural strength of the hose assembly, enabling it to withstand greater pressure and tension, and improves the overall safety and reliability. The stainless steel threaded ring 5 and the polytetrafluoroethylene braided layer 2 both have excellent corrosion resistance and can resist the erosion of various corrosive media, extending the service life of the hose. The polytetrafluoroethylene material has good high temperature resistance, which enables the braided layer 2 to maintain stable performance in high temperature environments and will not deform or age due to high temperature. The tight wrapping of the stainless steel threaded ring 5 and the braided layer 2 effectively protects the hose assembly from wear, reducing damage and maintenance costs caused by wear. The design of the threaded ring 5 not only enhances the structural strength of the hose, but also makes the hose assembly more stable when connected and not easy to loosen or fall off due to external force.

[0024] The working principle and usage of this utility model are as follows: First, ensure that flange 1 (3) and flange 2 (4) are aligned with each other. At this point, the four connectors 6 on the outside of flange 1 (3) correspond to the four cavities within flange 2 (4). Because connector 6 is designed as an arcuate structure and has a deformable cavity 7 inside, it has a certain elastic deformation capability. When connector 6 is inserted into the cavity of flange 2 (4), the arc-shaped protrusion deforms along the path of the deformable groove, allowing it to smoothly enter the cavity. As connector 6 is fully inserted, the deformable cavity 7 and the deformable groove on its inner wall gradually return to their original shape. The arc-shaped protrusion is now firmly engaged in the deformable groove, achieving a stable connection between the two hose bodies 1. The connection assembly of this utility model is simple and efficient, and the connection can be completed without the use of additional auxiliary tools, greatly improving work efficiency. The threaded ring 5 and braided layer 2 on the outside of the hose body 1 are designed primarily to enhance the overall performance and durability of the hose assembly. The threaded ring 5 acts as an additional protective layer, and its stainless steel material provides excellent corrosion resistance and mechanical strength. Braid 2 tightly wraps around threaded ring 5. Its polytetrafluoroethylene (PTFE) material provides it with excellent chemical and high-temperature resistance. In practical applications, when the hose assembly is in operation, whether conveying high-pressure media or facing complex external environments, threaded ring 5 and braid 2 play a vital role. The threaded ring 5, with its sturdy structure and stainless steel material properties, effectively resists external pressure and abrasion, protecting the hose body 1 from damage. At the same time, the polytetrafluoroethylene material of the braided layer 2 enables it to resist the erosion of various chemicals, as well as deformation and aging in high temperature environments, further extending the service life of the hose. The addition of the threaded ring 5 and the braided layer 2 significantly enhances the structural strength of the hose assembly, enabling it to withstand greater pressure and tension, and improves the overall safety and reliability. The stainless steel threaded ring 5 and the polytetrafluoroethylene braided layer 2 both have excellent corrosion resistance and can resist the erosion of various corrosive media, extending the service life of the hose. The polytetrafluoroethylene material has good high temperature resistance, which enables the braided layer 2 to maintain stable performance in high temperature environments and will not deform or age due to high temperature. The tight wrapping of the stainless steel threaded ring 5 and the braided layer 2 effectively protects the hose assembly from wear, reducing damage and maintenance costs caused by wear. The design of the threaded ring 5 not only enhances the structural strength of the hose, but also makes the hose assembly more stable when connected and not easy to loosen or fall off due to external force.
