DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the embodiments.

[0021] 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.

[0022] See also Figure 1-3 The utility model provides a hose assembly with a protective function, including two hose main bodies 1. The connecting ends of the two hose main bodies 1 are both provided with docking parts, and the docking parts include a No. 1 docking part 2 with an internal thread opened inside and a No. 2 docking part 201 with an external thread matching the internal thread opened outside. The two docking parts are respectively fixedly connected to the connecting ends of the two hose main bodies 1; when the hoses need to be docked, the No. 1 docking part 2 of one hose is aligned with the No. 2 docking part 201 of the other hose, and rotated so that the No. 2 docking part 201 is embedded in the No. 1 docking part 2, thereby completing the docking between the hoses.

[0023] Among them, the protective component is used to protect the connection of the hose body 1. The protective component is connected to the hose body 1. The protective component includes two protective members 3 connected to the outside of the hose body 1. The two protective members 3 are located on the outside of the hose body 1 and are provided with a connecting portion 301. The interior of the two connecting portions 301 fits with the outside of the hose body 1. The outer surfaces of the connection of the two connecting portions 301 are provided with a fixing portion 302. The two connecting portions 301 are fixedly connected by matching the fixing portion 302 and bolts. A positioning portion is provided on the fitting surface of one of the connecting portions 301. 303, a positioning groove 3032 is provided on the mating surface of the other connecting portion 301, which is adapted to the positioning portion 303. A protrusion 3031 is provided on the contact surface between the positioning portion 303 and the positioning groove 3032. When external protection of the hose joint is required, the two protective members 3 can be respectively placed on both sides of the hose body 1, so that the fixing portion 302 on one connecting portion 301 of the other two protective members 3 is embedded in the positioning groove 3032 on the connecting portion 301 of the other protective member 3. Bolts are used to secure the two fixing portions 302 at the matching positions. The tightening process of the bolts should ensure that the connection between the two protective members 3 is stable and not easy to loosen. During the fixing process, the protrusion 3031 on the contact surface between the positioning portion 303 and the positioning groove 3032 will provide additional fixing and anti-slip functions, ensuring that the two protective members 3 will not slide or misalign relative to each other at the connection.

[0024] Next, a protective part 304 is provided on one side of the two connecting parts 301, and the two protective parts 304 are wrapped around the outside of the hose joint. A plurality of annularly distributed elastic parts 306 are fixedly connected to the inside of the protective part 304, and a fitting part 305 is fixedly connected to one end of the elastic part 306 facing the axis of the protective part 304. The fitting part 305 fits the surface of the hose joint, and an arc-shaped guide surface 3051 is provided at one end of the fitting part 305. A weakening groove 3061 for deformation is provided on the outside of the elastic part 306. The protective part 3 is an integral injection molding structure. After the installation of the protective component is completed, the protective component can be translated as a whole toward the hose joint. First, the guide surface 3051 of the fitting part 305 will first contact the hose joint. When the protective component is installed close to the hose joint, the guide surface 3051 of the fitting part 305 will first make preliminary contact with the surface of the hose joint. This design cleverly utilizes the curved shape of guide surface 3051, allowing the protective assembly to more smoothly and accurately position itself at the hose joint during translation, avoiding friction damage or installation misalignment caused by direct collision. As the protective assembly continues to translate, guide surface 3051 gradually expands along the contour of the hose joint until the entire fitting 305 is completely in contact with the surface of the hose joint. During this process, the elastic portion 306 begins to deform due to the pressure from the hose joint, and this deformation is guided and controlled by the weakened groove 3061. The design of the weakened groove 3061 enables the elastic portion 306 to more evenly distribute stress when subjected to pressure, avoiding damage or permanent deformation caused by excessive local stress. It also enables the elastic portion 306 to better adapt to the shape differences of the hose joint, ensuring a tight fit between the fitting 305 and the hose joint. When the fitting 305 is fully fitted to the hose joint, the deformation of the elastic portion 306 reaches a stable state. At this time, the protective portion 304 is tightly wrapped around the outside of the hose joint through the support of the elastic portion 306. This wrapping not only provides physical protection, but also effectively reduces the impact of external shock or vibration on the hose joint through the buffering effect of the elastic portion 306. In addition, due to the close fit between the elastic portion 306 and the fitting 305, and the characteristics of the protective member 3 as an integral injection molded structure, the entire protective assembly is more structurally stable and less likely to loosen or deform due to external forces. This stability not only ensures the durability of the protective effect, but also improves the overall reliability and service life of the hose assembly.

[0025] The working principle and usage process of the present invention are as follows: first, when the hoses need to be docked, align the No. 1 docking piece 2 of one hose with the No. 2 docking piece 201 of the other hose and rotate them so that the No. 2 docking piece 201 is embedded in the No. 1 docking piece 2, thereby completing the docking between the hoses. When external protection of the hose docking point is required, the two protective pieces 3 can be respectively sleeved on both sides of the hose body 1, so that the fixing part 302 on one connecting part 301 of the other two protective pieces 3 is embedded in the positioning groove 3032 on the connecting part 301 of the other protective piece 3, and bolts are used to fix the connection at the matching position of the two fixing parts 302. The bolt tightening process ensures a secure and stable connection between the two guard members 3. During the tightening process, the raised portion 3031 on the contact surface between the positioning portion 303 and the positioning groove 3032 provides additional securing and anti-slip properties, preventing relative sliding or misalignment between the two guard members 3 at the connection. After the guard assembly is installed, the entire guard assembly can be translated toward the hose interface. Initially, the guide surface 3051 of the fitting 305 will make initial contact with the hose interface. This design cleverly utilizes the curved shape of the guide surface 3051, enabling smoother and more accurate positioning of the guard assembly during translation, avoiding friction damage or misalignment caused by direct collision. As the guard assembly further translates, the guide surface 3051 gradually expands along the contour of the hose interface until the entire fitting 305 is fully aligned with the hose interface. During this process, the elastic portion 306 begins to deform due to the pressure from the hose joint, and this deformation process is guided and controlled by the weakened groove 3061. The design of the weakened groove 3061 allows the elastic portion 306 to more evenly distribute the stress when subjected to pressure, avoiding damage or permanent deformation caused by excessive localized stress. It also allows the elastic portion 306 to better adapt to the shape differences of the hose joint, ensuring a tight fit between the fitting 305 and the hose joint. When the fitting 305 is fully attached to the hose joint, the deformation of the elastic portion 306 reaches a stable state. At this time, the protective portion 304, supported by the elastic portion 306, tightly wraps around the outside of the hose joint. This wrapping not only provides physical protection but also effectively reduces the impact of external shock or vibration on the hose joint through the cushioning effect of the elastic portion 306. Furthermore, the close fit between the elastic portion 306 and the fitting 305, as well as the integral injection-molded structure of the protective element 3, make the entire protective assembly more structurally stable and less susceptible to loosening or deformation due to external forces. This stability not only ensures the long-term protection effect, but also improves the overall reliability and service life of the hose assembly.
