Technical Field

[0001] The utility model relates to the technical field of pipe joints, in particular to an impact-resistant crimping hose joint. Background Art

[0002] Pipe fittings are parts used to install pipes in hydraulic systems or to install pipes on hydraulic components. They are a general term for connectors that can be installed and removed in fluid passages. Pipe fittings are mainly divided into welding type, ferrule type, crimping type and flaring type. The crimping type hose fitting mainly uses the crimping machine to shrink the die to connect the metal fitting and the hose. However, the existing hose fittings have the following shortcomings when used:

[0003] 1. The impact resistance of many hose joints is poor. After multiple impacts by the internal medium, the structure is prone to loosening, resulting in medium leakage, which is inconvenient to use.

[0004] Therefore, we propose an impact-resistant crimping hose connector. Utility Model Content

[0013] In a possible design, a first guide edge is provided on one side of the inner annular groove.

[0014] In a possible design, a second guide edge is provided at one end of the joint body.

[0015] In the present application, during installation, first place one end of the hose into the mounting tube to the deepest point, then pass one end of the connector body through the mounting tube and place it into the hose until the positioning ring and the mounting tube are in contact, then place the mounting tube into the shrinking mold of the crimping machine for processing, the shrinking mold squeezes the outer ring and then pushes the pressing block to squeeze the hose into the two first annular grooves, so that the hose is bent in multiple sections, thereby completing the positioning of the hose and completing the sealing through the two first sealing rings.

[0016] In the utility model, the impact-resistant crimping hose connector is provided with a plurality of structures such as a pressing block, a first annular groove and a sealing ring. When the crimping machine extrude and installs the tube, the pressing block can press the hose into the first annular groove, so that the hose is bent and extruded in the two first annular grooves respectively, thereby ensuring the limiting effect of the hose. In combination with the first sealing ring, the impact resistance of the hose connector is effectively improved, the sealing performance of the hose connector is ensured, and the leakage of the medium is avoided.

[0017] In the utility model, the impact-resistant crimping hose connector is provided with a plurality of structures such as a positioning ring, a first guide edge, and a second guide edge. The positioning ring can position the mounting tube, the first guide edge is used to position the hose, and the second guide edge can facilitate the fitting body to enter the hose, thereby providing convenience for structural assembly.

[0018] In the utility model, the limiting effect and sealing effect of the hose can be improved, thereby improving the impact resistance of the hose joint, avoiding medium leakage, and can also position and guide the structure, providing convenience for structural assembly.
