Embodiment
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed Thin explanation, it is therefore an objective to help design of the those skilled in the art to the utility model, technical solution have it is more complete, accurate and Deep understanding, and contribute to its implementation.
As shown in Figure 1, the utility model is a kind of hydralic hose high sealing connector, hydraulic fitting connection is improved The leakproofness at place, ensure that the stability of the hydraulic work system of engineering machinery.
Specifically, as shown in Figure 1, including connector 1, locking nut 1, connector 23, rubber ring 4, rubber pad 5 and locking nut 26, the connector 1 is equipped with annular groove 10, the locking nut 1 and the annular on connector 1 Groove 10 is rotatablely connected, and one 1 end of connector is equipped with convex shoulder 11, and the outer rim of the convex shoulder 11 is equipped with ring-shaped platform 12, described 23 outer wall of connector is equipped with external screw thread 30, and 23 end of connector is equipped with countersunk head platform 31, and the rubber ring 4 is installed on In countersunk head platform 31, the rubber pad 5 is sleeved on external screw thread 30, and the locking nut 26 is connected with external screw thread 30 by screw pair Connect, and the locking nut 26 is arranged on the left side of rubber pad 5.
As shown in Figure 1, the outside diameter of the convex shoulder 11 is identical with the oilhole internal diameter in connector 23.
As shown in Figure 1,11 outside front ends of convex shoulder are equipped with chamfering.
