Detailed Description
The utility model is described in further detail below with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, the oil inlet joint comprises an oil inlet joint 3 and a sealing ring 2, wherein the oil inlet joint 3 and the sealing ring 2 are installed on an oil inlet of a cylinder body 1.
As shown in fig. 2, an annular boss a is arranged in an oil inlet of the cylinder body 1, as shown in fig. 3, a port of the oil inlet connector 3 connected with the cylinder body 1 is designed as a clamping claw b, the clamping claw b is clamped and installed at the annular boss a after the oil inlet connector 3 is installed in the oil inlet of the cylinder body 1, specifically, the clamping claw b is provided with an outer flange, and the outer flange is embedded and clamped in the annular boss a; an annular groove is further formed in the oil inlet of the cylinder body 1 outside the annular boss a, a sealing ring 2 is installed in the annular groove, and the sealing ring 2 is located between the oil inlet of the cylinder body 1 and the oil inlet connector 3.
As shown in fig. 4, both the outer peripheral surface and the outer end surface of the sealing ring 2 are provided with annular protrusions c, the annular protrusions c on the outer peripheral surface of the sealing ring 2 are connected to the wall of an annular groove of an oil inlet of the cylinder body 1, the annular protrusions c on the outer end surface of the sealing ring 2 are slightly higher than the height of the oil inlet connector 3 matched with the cylinder body 1, and the annular protrusions c on the outer end surface of the sealing ring 2 are connected to the step surface of the outer flange of the oil inlet connector 3 outside the oil inlet of the cylinder body 1.
As shown in fig. 4, the inner circumferential surface of the sealing ring 2 may also be provided with an annular protrusion, and the annular protrusion on the inner circumferential surface of the sealing ring 2 is connected with the outer circumferential surface of the oil inlet joint 3 above the clamping claw b.
