Description

Technical Field

[0001] The utility model relates to the technical field of pipeline joints, in particular to a high-pressure hose sealing joint. Background Art

[0002] The existing high-pressure hose sealing joint fixes the hose through the joint and the clamping assembly. However, when it is used, it only clamps and fixes the hose from the outside to the inside, and the fixing strength is weak. When subjected to external forces, the connection is easily disconnected directly. For example, a Chinese patent discloses a "high-pressure hose sealing joint" with an application number of "202321650021.9". This device drives two screws to rotate respectively by controlling the rotation of the output shafts of two forward and reverse motors. The rotation of the two screws drives two connection blocks to slide up and down inside two U-shaped frames through thread cooperation with the corresponding connection blocks. Controlling the up and down sliding of the two connection blocks drives two anti-loosening clamping half-rings to clamp the hose, facilitating the hose to be more firmly sleeved outside one end of the core pipe, and facilitating the provision of a better reinforcement and anti-loosening function. However, when it is used, it only clamps and fixes the hose from the outside to the inside, and the fixing strength is weak. When subjected to external forces, the connection is easily disconnected directly. Summary of the Utility Model
