Description

Technical Field

[0001] This utility model belongs to the field of oil pipe technology, specifically relating to a connecting oil pipe with a multi-hole coaxial arrangement structure. Background Technology

[0002] As the name suggests, an oil supply device is a device that delivers oil to oil-requiring equipment. It supplies stored hydraulic oil to the corresponding hydraulic machine, thereby driving it to perform specified tasks. After the hydraulic machine completes its task, the hydraulic oil flows back to the oil tank of the oil supply device, creating a circulation system to ensure a continuous supply of oil to the hydraulic machine from subsequent devices.

[0003] In existing technology, hydraulic devices typically have multiple oil outlet joints. Each oil outlet joint is equipped with a return oil pipe for returning hydraulic oil to the oil supply device. However, too many return oil pipes can easily become tangled and intertwined during installation. This increases the workload for workers during later maintenance and replacement of the return oil pipes. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a connecting oil pipe with a multi-hole coaxial arrangement structure to solve the technical problem of easy backflow oil pipes in existing hydraulic devices becoming intertwined.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0006] A connecting oil pipe with a multi-hole coaxial arrangement structure includes multiple oil delivery joints and multiple oil delivery pipes. The various oil delivery joints are connected in series through the respective oil delivery pipes.

[0007] The oil connector has an oil inlet and an oil outlet at its top and bottom, respectively. One side of the oil connector has an oil outlet that communicates with the oil inlet and the oil outlet.

[0008] Furthermore, a flow chamber is provided on the oil delivery connector. The oil inlet, oil outlet, and oil delivery port are all connected to the flow chamber.

[0009] Furthermore, an oil drain port is provided on the side of the oil connector facing away from the oil inlet. The oil drain port is connected to the flow chamber on the oil connector. A removable and fixed plug is provided at the oil drain port of the oil connector.

[0010] Furthermore, there are a total of eight oil delivery connectors.

[0011] Furthermore, the oil connector located at the head end is only provided with an oil outlet.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This invention sets up multiple oil delivery joints that cooperate with the oil outlet joints on the hydraulic device, and connects each oil delivery joint in series through multiple oil delivery pipes. This allows the oil outlet joints on the hydraulic device to discharge oil in a centralized and directional manner, effectively avoiding the problem of excessive return oil pipes installed on the oil outlet joints causing the return oil pipes to become tangled and intertwined, thus increasing the workload of the staff when maintaining and replacing the return oil pipes later.

[0017] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1 and 2 As shown, a connecting oil pipe with a multi-hole coaxial arrangement structure includes multiple oil delivery joints 1 and multiple oil delivery pipes 2. Each oil delivery joint 1 has an oil delivery port 3. The oil delivery joint 1 is installed on the oil outlet of the corresponding oil discharge machine through the oil delivery port 3. The various oil delivery joints 1 are connected in series through the oil delivery pipes 2, so that the multiple oil outlets of the oil discharge machine can achieve centralized oil discharge.

[0020] The specific structure is as follows: Figure 2 As shown, the oil connector 1 has an oil inlet 4 at its top and an oil outlet 5 at its bottom. A flow chamber 6, communicating with the oil inlet 4 and the oil outlet 5, is located in the middle of the oil connector 1. An oil outlet 3 is located on one side of the oil connector 1.

[0021] When the oil outlet 5 on the oil discharge machine is discharging oil, each oil delivery connector 1 is installed on the corresponding oil outlet connector. The oil discharged by the oil discharge machine enters the flow chamber 6 through the oil delivery port 3, and is then discharged in a centralized and directional manner through each oil delivery pipe 2 connected to the oil outlet 5 of each oil delivery connector 1.

[0022] Furthermore, an oil drain port 7 is provided on the side of the oil connector 1 facing away from the oil inlet 3. The oil drain port 7 is connected to the flow chamber 6 on the oil connector 1. A removable plug is provided at the oil drain port 7 of the oil connector 1. During operation, when the corresponding connector is not in use, each oil connector 1 is equipped with a corresponding plug, and the oil discharged by the oil draining machine is output from the oil connector 1 at the tail end. When it is necessary to divert and drain the oil, the plug on one of the oil connectors 1 is removed and a diversion pipe is installed to achieve diversion and draining of the oil.

[0023] In this embodiment, there are eight oil supply connectors 1 in total. Among them, the oil supply connector 1 located at the first end is only provided with an oil outlet 5.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
