Specific embodiment
The utility model is described further below with reference to Fig. 1.
Oil cylinder with rotary joint, it is high-voltage oil cylinder that this, which has oil cylinder, including oil cylinder main body 10 and is arranged in oil cylinder main body
The end of the rotary joint of 10 side walls, rotary joint is communicated with oil pipe.Rotary joint is L-type structure, is disposed in rotary joint
The pipeline road communicated with 10 inner cavity of oil cylinder main body.
The rotary joint includes being mounted on the fixed body 20 of 10 side wall of oil cylinder main body and covering the rotation on fixed body 20
Body 30, rotary body 30 can be freely rotated around fixed body 20 makes pipeline road lead to any direction.In addition, in the present embodiment, it is described
The external connection part 40 being mounted on rotary body 30 is also devised in rotary joint.
The first pipeline communicated with 10 inner cavity of oil cylinder main body, the lateral surface cloth of fixed body 20 are disposed in the fixed body 20
It is equipped with the annular oil groove 24 communicated with the first pipeline, the second pipeline communicated with annular oil groove 24 is disposed in rotary body 30, it is right
The third pipeline communicated with the second pipeline is disposed in outer connector 40.
The lateral surface of the fixed body 20 is disposed with annular protrusion and annular groove, and snap ring 23 is disposed in annular groove,
Region between snap ring 23 and annular protrusion is the region being inserted in for rotary body 30.In the present embodiment, snap ring 23 is located at ring
The lower section of shape protrusion.
