[0003] In summary: In the above case, the high-pressure hose assembly is pressure-relieved by manual pressure relief. However, when using the manual pressure relief method, there are not only limitations but also a risk of danger due to the inability to relieve pressure in a timely manner. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-pressure hose assembly with a rapid pressure relief function for the deficiencies of the prior art, so as to solve the problem that in the above case, the high-pressure hose assembly is pressure-relieved by manual pressure relief, but when using the manual pressure relief method, there are not only limitations but also a risk of danger due to the inability to relieve pressure in a timely manner.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A high-pressure hose assembly with a rapid pressure relief function includes a high-pressure hose assembly structure, and an automatic pressure relief structure is arranged inside the high-pressure hose assembly structure;

[0006] The structure of the high-pressure hose assembly includes a high-pressure hose assembly body as the main body. A connection groove is provided on the surface of the high-pressure hose assembly body, and a through hole extending into the high-pressure hose assembly body is penetrated inside the connection groove.

[0007] The surface of the high-pressure hose assembly body is sprayed with a carbon fiber layer, and a high-temperature resistant, heat-insulating coating layer is sprayed on the surface of the carbon fiber layer.

[0020] (1) In this case, by setting up an automatic pressure relief structure, the problem in the above case of relieving the pressure of the high-pressure hose assembly through manual pressure relief is solved. However, when using the manual pressure relief method, there are not only limitations but also a risk of failure to relieve the pressure in a timely manner, which may lead to danger. When the internal pressure of the high-pressure hose assembly body is relatively high, the pressure is transmitted to the inside of the matching pipe. The pressure entering the inside of the matching pipe pushes the adjusting ball to move under force. During the movement of the adjusting ball under force, the connecting pipe is driven to pierce through the elastic sealing cushion and extend outside the matching pipe. When the connecting pipe extends outside the matching pipe, the pressure transmitted to the inside of the matching pipe is discharged through the pressure relief groove for pressure relief treatment;

At the same time, in the working environment, the high-pressure hose assembly will also be corroded by other substances, resulting in a reduced service life and an increased replacement cost.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-5 , the present utility model provides a technical solution: a high-pressure hose assembly with a rapid pressure relief function, as Figure 1 , Figure 2 and Figure 3 shown, which includes a high-pressure hose assembly structure 1. The high-pressure hose assembly structure 1 includes a high-pressure hose assembly body 101 as the main body, and a connection groove 102 is provided on the surface of the high-pressure hose assembly body 101. At the same time, a through hole 103 extending into the high-pressure hose assembly body 101 is penetrated inside the connection groove 102.

[0030] In the above solution, further, a carbon fiber layer 104 is sprayed on the surface of the high-pressure hose assembly body 101, and a high-temperature heat-insulating coating layer 105 is sprayed on the surface of the carbon fiber layer 104.

[0031] As Figure 4 and Figure 5 shown, an automatic pressure relief structure 2 is provided inside the high-pressure hose assembly structure 1. The automatic pressure relief structure 2 includes a connection pipe 201 with a hollow structure inside, and pressure relief grooves 202 are penetrated on the surface of the connection pipe 201. There are 4 pressure relief grooves 202, and the pressure relief grooves 202 are arranged in a circular array with respect to the connection pipe 201. When there are 4 through the above structure, it not only reflects the practicability of the above structure arrangement, but also reflects the penetration and pressure discharge and transportation of the above structure arrangement. And when there are 4 through the above structure, it also reflects the symmetry and aesthetic practicability of the above structure arrangement. At the same time, the connection pipe 201 is fixedly connected with the adjustment ball 203, and the adjustment ball 203 and the connection pipe 201 are arranged in a "spherical lightning rod" shape. When the connection shape of the above two is in a "spherical lightning rod" shape, it not only reflects the integrity of the installation connection of the above two, but also reflects the synchronous force-driven adjustment of the installation connection of the above two. And when the connection shape of the above two is in a "spherical lightning rod" shape, it also reflects the axis symmetry of the above two in the axial and longitudinal directions. Among them, the adjustment ball 203 is made of a foam ball, and the connection pipe 201 is made of a high molecular polyethylene pipe, which effectively reduces the weight of the above two and facilitates the pressure to adjust the force on the above two.

[0032] Further in the above solution, the adjusting ball 203 is movably installed inside the supporting pipe 204, and a through-hole disc 205 is installed on the supporting pipe 204. At the same time, an elastic sealing cushion 206 is installed on the through-hole disc 205. There are 4 elastic sealing cushions 206, and the elastic sealing cushions 206 are installed around the through-hole disc 205. When there are 4 of the above components, the surrounding installation of the above components on the through-hole disc 205 is reflected, and the mutual contact and mutual force separation after the surrounding installation of the above components are also reflected. And when there are 4 of the above components, the practicability of the installation of the above components is also reflected at the same time.

[0033] In the above solution, when the internal pressure of the high-pressure hose assembly 101 is relatively high, the pressure is then conveyed inside the supporting pipe 204. The pressure entering the inside of the supporting pipe 204 pushes the adjusting ball 203 to move under force. During the process of the adjusting ball 203 moving under force, it drives the connecting pipe 201 to pierce through the elastic sealing cushion 206 and extend outside the supporting pipe 204. When the connecting pipe 201 extends outside the supporting pipe 204, the pressure conveyed inside the supporting pipe 204 is discharged through the pressure relief groove 202 for pressure relief. After the pressure relief is completed, at this time, the adjusting ball 203 and the connecting pipe 201 fall inside the supporting pipe 204 to seal the inside of the supporting pipe 204.

[0034] The orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only a simplified description for facilitating the description of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation on the protected content of the present invention.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
