Description

Technical fields:

[0001] This utility model relates to the technical field of cast shell caps, and more specifically to shell oil cap assemblies. Background technology:

[0002] Currently, automobiles contain many housings, such as fuel tank housings and electrical control box housings. These housings typically require cover plates for sealing. These cover plates are generally cast, and some cover plates also need to accommodate inlet and outlet pipes. These pipes are usually connected to the housing, and the installation of these components follows a specific sequence; installing or removing the inlet or outlet pipe requires first removing the cover plate. However, installing and fixing inlet and outlet pipes within some housings can interfere with the installation of other components, necessitating an increase in housing volume. This increases the weight. Therefore, some have proposed installing the inlet and outlet pipes directly on the cover plate to avoid interference with internal components. This requires the development of a cover plate assembly that integrates the inlet and outlet pipes with the cover plate, while also ensuring a tight fit and easy installation. Utility Model Content:

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a housing oil cap assembly. The housing oil cap assembly consists of a housing cap, an inlet pipe, and an outlet pipe. The inlet pipe and outlet pipe are easy to install and connect to the housing cap, and they fit tightly with the housing cap, making it less prone to leakage at the connection.

[0004] The housing oil cap assembly includes a disc-shaped housing cap, the outer ring of which is formed with a flange edge, and several mounting holes are formed on the flange edge.

The lower end of the second tube body is formed with an outlet tube connector. Circular positioning protrusions are formed on the outer wall of the middle and upper parts of the second tube body. The outer wall of the positioning protrusions abuts against the inner wall of the sealing seat ring. The lower end of the positioning protrusions is formed with a lower retaining ring, which abuts against the lower surface of the shell cover. The upper end of the second tube body extends out of the shell cover and is formed with an upper retaining ring.
