Description

Technical Field

[0001] The utility model belongs to the technical field of rubber tubes, and in particular relates to a high-pressure flexible rubber hose. Background Art

[0002] When high-pressure flexible rubber hoses are used, they often need to be connected to pipe joints. The traditional connection method is usually to connect them through resin and joints. Although this connection method has certain advantages in some aspects, it also has some disadvantages and inconveniences. As a result, the following problems exist: 1. The hose connected by resin has a strong fixity. Once the connection is fixed, it is difficult to disassemble easily, which means that when the hose needs to be replaced or repaired, it takes more time and effort; 2. Due to the characteristics of the connection between resin and joints, once removed, it is usually not reusable. This connection method cannot be reused, which increases costs and wastes resources; 3. The installation and disassembly process of the connection through resin and joints is relatively complicated and requires experienced and professional personnel to operate, which increases the difficulty of the installation and maintenance process and may cause operational errors and damage to the hose.

[0003] Therefore, it is necessary to design a new high-pressure hose structure to solve the above problems. Utility Model Content
