Description

Technical Field

[0001] The invention relates to the technical field of hydraulic hoses, in particular to a high-strength hydraulic hose assembly with a freely positioned butt joint. Background Art

[0002] Hydraulic hoses, also known as hydraulic oil pipes, hydraulic hoses, high-pressure hoses or hydraulic pipes, are mainly composed of synthetic rubber. When in use, hydraulic hoses need to be connected to hydraulic equipment through hose joints, so that they can stably transport high-pressure hydraulic oil. The hydraulic equipment will move during use, and will drive the hydraulic hose to move accordingly to ensure the normal use of the hydraulic equipment. In order to ensure the stable docking of the hydraulic hose and the hydraulic equipment, a highly sealed joint is required, in which the joint and the hydraulic hose form an integrated connection structure.

[0003] However, the existing hydraulic hose assemblies still have certain defects when used; For example, a hydraulic hose connector proposed in application number CN202210317665.X includes a hose, a threaded sleeve, a buckle connector and an anti-slip nut. The buckle connector is threadedly matched with the threaded sleeve to buckle and clamp the hose between the threaded sleeve and the buckle connector, and at the same time, the connecting end face of the threaded sleeve and the buckle connector is tightly attached to the side end face of the annular rubber anti-slip part in the compartment. The buckle connector has a buckle slope that matches the hose connection end. The present invention can perform secondary anti-slip fixation on the threaded sleeve and the buckle connector through the anti-slip nut. The setting of the annular rubber anti-slip part improves the bonding degree between the hose connection end and the threaded sleeve and the buckle connector. By setting the buckle slope on the buckle connector, the thickness of the hose connection end can be gradually increased with the increase of the contact area between the threaded sleeve and the buckle connector, thereby achieving the purpose of improving the effect of preventing the hose from falling off. In actual use, the following problems still exist: The hydraulic hose connector adopts a threaded fixed connection method during the connection process. When the angle of the connected hydraulic equipment changes, the connection between the hydraulic hose and the connector will bend. Long-term bending will cause damage to the hydraulic hose, thereby reducing the service life and use effect of the hydraulic hose. During the process of transporting hydraulic oil at the connection between the connector and the hydraulic equipment, the residue and impurities in the hydraulic oil will directly accumulate inside the mounting base of the connector and the hydraulic equipment. The impurities accumulated inside are not easy to clean, and a large amount of accumulation can easily cause blockage. In addition, the threaded connection method is not easy to disassemble and maintain.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the present case.
