Long oil outlet pipe special for automobile tailgate power unit

Abstract

This utility model discloses a dedicated long oil outlet pipe for a car tailgate power unit, including a pipe body with a first threaded connector and a second threaded connector at both ends. A retaining plate is provided on the inner wall of the pipe body near the first threaded connector. Two to three layers of filter screens are stacked inside the first threaded connector, with one end of the filter screen abutting against the retaining plate. An annular groove is formed on the inner wall of the pipe body on the side of the retaining plate, and a retaining spring is installed in the annular groove, abutting against one end of the filter screen. The inner diameter of the retaining spring is smaller than the diameter of the filter screen. The multiple layers of filter screens filtering impurities such as iron filings in the hydraulic oil prevent them from flowing into the hydraulic valve with the hydraulic oil, and also facilitate disassembly and cleaning, thereby avoiding damage to the hydraulic valve core and ensuring the normal operation of the equipment.

Description

Technical Field

[0001] This utility model belongs to the field of oil pipe technology, and in particular relates to a long oil pipe for a power unit on the tailgate of an automobile. Background Technology

[0002] The tailgate power unit is a compact hydraulic system. Its basic working principle is as follows: a DC motor (powered by the vehicle battery) drives a high-pressure gear pump, drawing hydraulic oil from the tank and generating a high-pressure oil flow. This high-pressure oil is then delivered to the tailgate's lifting or tilting cylinders via various hydraulic valves on an integrated valve block, thereby driving the tailgate to perform various actions. During long-term operation, impurities such as iron filings can accumulate in the oil. Current oil outlet pipes lack mechanisms to intercept these impurities, easily damaging the valve cores and causing equipment malfunction. Utility Model Content

[0003] To solve the above problems, this utility model provides a dedicated long oil pipe for the power unit of the automobile tailgate.

[0004] This utility model is implemented as follows: A dedicated long oil outlet pipe for a car tailgate power unit includes a pipe body. A first threaded connector and a second threaded connector are fixedly installed at both ends of the pipe body for easy connection to equipment. The first and second threaded connectors are hollow and connected to the interior of the pipe body to facilitate the flow of hydraulic oil. A retaining plate is provided on the inner wall of the pipe body near the first threaded connector to limit and block the filter screen. Two to three layers of filter screens are stacked inside the first threaded connector, with one outer edge of each filter screen abutting against the retaining plate. Impurities such as iron filings in the hydraulic oil are filtered through these multiple layers of filter screens. To prevent the filter from flowing into the hydraulic valve with the hydraulic oil, the diameter of the clamping platform at its widest point, the diameter of the filter screen, and the inner diameter of the first threaded connector are the same, ensuring that the filter screen moves smoothly to the clamping platform and abuts against it. An annular groove is formed on the inner wall of the tube on the side of the clamping platform near the first threaded connector to limit the position of the retaining spring. The diameter of the annular groove is larger than the inner diameter of the first threaded connector, and a retaining spring is installed in the annular groove. The retaining spring abuts against the outer edge of one end of the filter screen, and the inner diameter of the retaining spring is smaller than the diameter of the filter screen. The retaining spring limits the position of the filter screen to ensure that the filter screen does not move.

[0005] Preferably, the diameter of the filter screen is 10mm to 15mm.

[0006] Preferably, the filter screen has a mesh size of 35 to 45 mesh to ensure a reliable filtration effect on impurities such as iron filings.

[0007] Preferably, a washer is fitted on the second threaded connector.

[0008] The beneficial effects of this utility model are: 2 to 3 layers of filter screens are stacked inside the first threaded joint, and the outer edge of one end of the filter screen abuts against the clamp. The multi-layer filter screens filter impurities such as iron filings in the hydraulic oil, preventing them from flowing into the hydraulic valve with the hydraulic oil. At the same time, it is easy to disassemble and clean, thereby avoiding damage to the hydraulic valve core and ensuring the normal use of the equipment. Attached Figure Description

[0010] To better understand the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, further illustrates this utility model.

[0011] like Figure 1 and 2 The illustrated extended oil pipe for a car tailgate power unit includes a pipe body 1. A first threaded connector 2 and a second threaded connector 3 are fixedly installed at both ends of the pipe body 1 for easy connection to equipment. A washer 8 is fitted onto the second threaded connector 3. The first threaded connector 2 and the second threaded connector 3 are hollow and interconnected with the interior of the pipe body 1 to facilitate the flow of hydraulic oil. A retaining plate 4 is provided on the inner wall of the pipe body 1 near the first threaded connector 2 to limit and block the filter screen 5. Two layers of filter screen 5 are stacked inside the first threaded connector 2, with one outer edge of each filter screen 5 abutting against the retaining plate 4. The multiple layers of filter screen 5 filter impurities such as iron filings in the hydraulic oil, preventing them from flowing into the hydraulic valve with the hydraulic oil. The diameter of the filter screen 5 is 12mm. The mesh size of the filter screen 5 is 40 mesh, ensuring reliable filtration of impurities such as iron filings. The diameter of the wide part of the clamping platform 4 and the diameter of the filter screen 5 are the same as the inner diameter of the first threaded connector 2, ensuring that the filter screen 5 moves smoothly to the clamping platform 4 and abuts against the clamping platform 4. An annular groove 6 is provided on the inner wall of the tube body 1 on the side of the clamping platform 4 near the first threaded connector 2 to limit the position of the retaining spring 7. The diameter of the annular groove 6 is larger than the inner diameter of the first threaded connector 2. The retaining spring 7 is provided in the annular groove 6 and abuts against the outer edge of one end of the filter screen 5. The inner diameter of the retaining spring 7 is smaller than the diameter of the filter screen 5. The retaining spring 7 limits the position of the filter screen 5 to ensure that the filter screen 5 will not move.

[0012] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
