Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment is as follows:

as shown in fig. 1, the present embodiment provides a hydraulic pipe joint, which includes an intermediate joint 1, a nut 3 and a ferrule 2, where a first connecting portion is disposed at an end of the intermediate joint 1, the ferrule 2 is sleeved on a hydraulic pipe 4, and the nut 3 is connected with the first connecting portion in a matching manner to fix the ferrule 2 between the intermediate joint 1 and the nut 3, and between the hydraulic pipe 4.

In this embodiment, as shown in fig. 1 to 2, the intermediate joint 1 is made of a steel material with a relatively high hardness, and first connecting portions are respectively machined at two ends thereof, in this embodiment, the first connecting portions are external threads; a through channel is arranged in the center of the middle joint 1, the inner diameter of the through channel is the same as that of the hydraulic pipe 4, limiting grooves are arranged at two ends of the through channel, the inner diameter of each limiting groove is the same as the outer diameter of the hydraulic pipe 4, and therefore the position of the end head of the hydraulic pipe 4 is limited through the limiting grooves; the outside of spacing groove sets up the tapered groove again, and the contained angle of tapered groove and 1 axis of intermediate head is 5-45, and in this embodiment, the contained angle of tapered groove and axis is 30 degrees.

Nut 3 chooses for use hexagonal cutting ferrule nut to, when screwing up nut 3, can compress tightly cutting ferrule 2 between nut 3 and intermediate head 1 through nut 3, and make all form sealedly between cutting ferrule 2 and nut 3, intermediate head 1 and the hydraulic pressure pipe 4 through 3 extrusion to cutting ferrule 2 of nut, avoid hydraulic oil to leak.
