Preferably, the outside diameter of the convex shoulder is identical with the oilhole internal diameter in connector two.
Preferably, the convex shoulder outside front ends are equipped with chamfering.
Preferably, the width of the rubber ring is bigger 5-8mm than the length of convex shoulder.
It is using the beneficial effect of above technical scheme：Hydralic hose high sealing connector, it is described in installation process
One one end of connector is connected with a high-pressure oil pipe, and described two one end of connector is connected with an other high-pressure oil pipe, then will
Connector two rotates locking nut one, locking nut one is connected with the external screw thread on two outer wall of connector close to connector one,
Until in the oilhole in the convex shoulder insertion connector two of connector one end, and making the rubber in two end countersunk head platform of connector
Circle is firmly compressed by the ring-shaped platform in convex shoulder outer rim, then twists locking nut two again, rubber pad is firmly pressed on locking screw
On the end face of mother one, rubber ring and rubber pad are firmly compressed by sealing by locking nut one and locking nut two, improve liquid
The leakproofness of pressure pipe joint junction, ensure that the stability of the hydraulic work system of engineering machinery.
In addition the outside diameter of the convex shoulder is identical with the oilhole internal diameter in connector two, is connected in connector one and connector two
Afterwards, it is inserted into due to the convex shoulder in the oilhole in connector two, rubber ring is not contacted with hydraulic oil, avoid hydraulic oil to rubber
The corrosion of cushion rubber；The convex shoulder outside front ends are equipped with chamfering, facilitate connector one and are engaged with aligning for connector two；The rubber
The width of cushion rubber is bigger 5-8mm than the length of convex shoulder, ensure that the air-tightness that connector one is connected with connector two.

Embodiment
Below against attached drawing, by the description of the embodiment, making to embodiment of the invention further details of
Explanation, it is therefore an objective to help those skilled in the art to have more complete, accurate and deep reason to design of the invention, technical solution
Solution, and contribute to its implementation.
As shown in Figure 1, the present invention is a kind of hydralic hose high sealing connector, hydraulic fitting junction is improved
Leakproofness, 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.
