Embodiment Construction

[0014] The present invention as figure 1 , 2 shown.

[0015] The universal joint of the front telescopic sleeve hydraulic cylinder of the dump truck includes a hydraulic cylinder 1, and a joint seat 2 is correspondingly installed on the oil inlet hole 9 on the side of the hydraulic cylinder 1, and a hollow pipe 10 is arranged inside the joint seat 2. Empty pipe 10 corresponds to oil inlet hole 1 9, and joint seat 2 is provided with a plurality of oil inlet holes 2 3 that communicate with hollow pipe 10 in the radial direction, corresponding to a plurality of oil inlet holes 2 3. Rotary joint 4 is provided on joint seat 2 , the inner side of the rotary joint 4 forms an annular channel 6 outside the plurality of oil inlet holes 3, and the annular channel 6 and the oil inlet hole 5 of the rotary joint 4 are connected.

[0016] Sealing rings 7 are provided on both sides of the annular channel 6 of the rotary joint 4 , and the sealing rings 7 make the rotary joint 4 and the joint...

Abstract

The invention provides an oil inlet / outlet connector of a front telescopic sleeve hydraulic oil cylinder of a dumper. The oil inlet / outlet connector of the front telescopic sleeve hydraulic oil cylinder of the dumper comprises the hydraulic oil cylinder. A connector base is correspondingly installed on a first oil inlet in the side face of the hydraulic oil cylinder. A hollow pipe is arranged in the connector base and corresponds to the first oil inlet. A plurality of second oil inlets communicated with the hollow pipe are formed in the connector base in the radial direction. A rotary connector corresponding to the multiple second oil inlets is arranged on the connector base. The inner side of the rotary connector forms an annular channel outside the multiple second oil inlets, and the annular channel is communicated with an oil inlet of the rotary connector. Sealing rings are arranged on the two sides of the annular channel of the rotary connector, and the rotary connector and the connector base form a relative sealing environment through the sealing rings. A check ring is arranged on the connector base and located outside the rotary connector. According to the oil inlet / outlet connector of the front telescopic sleeve hydraulic oil cylinder of the dumper, 360-degree rotation and connection of the connector of the hydraulic oil cylinder can be achieved without direction limitation; the structure is simple, the problem of interference of the installation process is solved, and thus installation is smoother.

Description

technical field [0001] The invention relates to the manufacturing field of oil cylinders in dump truck parts, in particular to an oil inlet and outlet joint connected with a telescopic sleeve hydraulic cylinder at the front of the dump truck and a high-pressure oil pipe of a hydraulic system. Background technique [0002] The oil inlet and outlet of the front telescopic sleeve hydraulic cylinder of the traditional dump truck is a straight-through joint. The size of the required oil tank is also different. When the installation space of the hydraulic system is relatively compact, it is difficult to bend the high-pressure oil pipe with steel wires in the structure to a suitable direction and connect it with the joint. Convenience. Contents of the invention [0003] The purpose of the present invention is to solve the problem of compact installation space and versatility of the dump truck hydraulic system, the oil inlet and outlet joints of the front telescopic sleeve hydrau...
