Abstract

The invention relates to an oil pan and an oil plug cap used on the oil pan. The oil pan oil plug cover consists of a columnar plastic body with two ends respectively being the insertion end and the cut-off end. The surface of the body is also provided with a guide groove including a guide groove and a first transverse area, and a protrusion is fixedly connected to the cut-off end. The platform has a protruding clamping post on the end face of the boss connected to the body. The oil sump includes a plastic shell provided with an oil drain hole, the inner wall of the oil drain hole has a guide column suitable for being inserted into the guide groove and the first transverse area, and the outer end surface of the oil drain hole has a guide column for When the clamping post slides into the slot, the guide post can be located in the first transverse area of ​​the guide slot. The guide column of the oil pan enters the first transverse area of ​​the guide groove on the oil pan cover, and the clamping column enters the slot, so that the oil cover of the oil pan can be installed accurately and the connection degree is ensured. Consistency ensures the anti-loosening effect.

Description

technical field [0001] The invention relates to a sealing cover, in particular to an oil pan oil plugging cover used on an oil pan, and also relates to an oil pan installed with the oil pan oil plugging cover. Background technique [0002] With the improvement of manufacturing technology, the oil pan used in automobiles has changed from aluminum to plastic. Due to the change of material, the oil pan oil plug cap originally installed on the oil drain hole of the oil pan is tightened. Not one, the anti-loosening effect is not good, and the phenomenon of detachment may occur when subjected to vibration and impact, resulting in oil leakage accidents. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides an oil plug cover and an oil pan, which effectively ensure the consistency of the connection degree between the two, and have a better anti-loosening effect. [0004] In order to achieve the above object, the oil...
