High-strength oil adding pipe

Abstract

The invention provides a high-strength oil adding pipe. The high-strength oil adding pipe comprises an oil pipe main body, wherein the oil pipe main body includes a first pipe body, a pipe body connecting part and a second pipe body; the pipe body connecting part is connected with the first pipe body and the second pipe body respectively, and the pipe body connecting part enables the first pipe body and the second pipe body to form a bent structure; the port of the first pipe body is provided with a pipe cap interface, the port of the second pipe body is provided with an interface; the oil pipe main body is further provided with a third pipe body, the third pipe body is arranged on one side of the second pipe body; the side surface of the second pipe body is further provided with a connecting block, and the middle part of the connecting block is further provided with a long strip groove.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a high-strength oil filling pipe. Background technique [0002] The engine must be equipped with an oil filling port, which is usually achieved by setting a fuel oil pipe assembly at a certain position on the cylinder block or other structural parts that communicate with the oil pan. At the same time, the oil pipe assembly must be under 0.1MPa pressure No leakage occurs. The oil filler pipe in the prior art consists of a pipe body of metal material and a pipe body of plastic material. Among them, metal materials [0003] The feed oil pipe is made of steel pipe with a wall thickness of 1.2-3mm. Due to the requirements of the installation of the cover and space bending, especially for the requirements of the pipe body with complex space bending and variable diameter, the pipe body needs to be welded in sections with pipes of different shapes. As a result, the assembly and positioning of...

Problems solved by technology

[0003] The feed oil pipe is made of steel pipe with a wall thickness of 1.2-3mm. Due to the requirements of the installation of the cover and space bending, especially for the requirements of the pipe body with complex space bending and variable diameter, the pipe body needs to be welded in sections with pipes of different shapes. As a result, the assembly and positioning of the cover and other components need to be welded or riveted to related structural parts. This structural product has a complex structure, heavy weight, and high process cost. Due to the large number of welding parts, the risk of failure is high and the appearance is not beautiful; the addition of plastic materials The oil pipe achieves the purpose of light weight, but for the complex space bending structure, its application is limited by the conditions of high temperature resistance and corrosion resistance, and strict and tedious strength and reliability judgments are required for each product, resulting in a new product development cycle. long
