Detailed Description

The accompanying drawings, which are incorporated in and constitute a part of this application, illustrate preferred embodiments of the utility model and together with the description, serve to explain the principles of the utility model and not to limit the scope of the utility model.

As shown in fig. 1, 2, and 3, an embodiment of the present invention provides a servomotor joint, which includes a main body 1 and a sealing washer 2, wherein an annular groove 3 is formed in an end portion of the main body 1, which is in butt joint with an oil pipe, and the sealing washer 2 is installed in the annular groove 3.

Specifically, the main body 1 includes a first connection pipe 11 and a second connection pipe 12, one end of the first connection pipe 11 is coaxially fixed with one end of the second connection pipe 12, the annular groove 3 is formed in an end surface of the other end of the first connection pipe 11, and the other end of the second connection pipe 12 forms a connection end connected with the servomotor.

Furthermore, the first adapter tube 11 and the second adapter tube 12 are made of PVC.

Furthermore, a plurality of mutually staggered abutting blocks 31 are formed on the inner wall of the annular groove 3 in an extending manner, and the abutting blocks 31 abut against the part of the sealing gasket 2 extending into the annular groove 3.

It can be understood that the mutually staggered abutment blocks 31 in the annular groove 3 form a serpentine channel, and the sealing gasket 2 is clamped in the serpentine channel, so that the sealing gasket is firmer; is not easily detached from the main body 1.

Furthermore, the bottom surface of the annular groove 3 is coated with adhesive, and the part of the sealing gasket 2 extending into the annular groove 3 is fixed with the bottom surface of the annular groove 3 through the adhesive. Seal ring 2 through paste with joint dual mode with ring channel 3 is fixed, can avoid appearing seal ring 2 is relative the condition that main part 1 drops.
