Description

Thread cover plate structure of automobile oil filter

Technical Field

The utility model relates to a car oil cleaner's thread cover plate structure.

Background

The filter is a filter that filters impurities or gas through filter paper. Generally referred to as an automobile filter, is an accessory of an engine. The method is divided into the following steps according to different filtering functions: oil filters, fuel filters (gasoline filters, diesel filters, oil-water separators, hydraulic filters), air filters, air-conditioning filters, and the like. The engine has three filters of air, engine oil and fuel oil, generally called three filters, and an air-conditioning filter, commonly called four filters. Respectively takes charge of the filtration of a lubricating system, a medium in a combustion system, an engine air inlet system and a carriage air circulating system. But the sealing performance of the oil inlet is not good at present, and the sealing performance of the sealing ring can not meet the installation requirement of the existing filter though the sealing ring is arranged on the sealing ring fixing plate.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect that exists among the prior art, provide a car oil cleaner's thread cover plate structure, increased the sealing performance of sealing washer on the sealing washer fixed plate, increased the leakproofness of filter oil feed hole department, solved the poor problem of leakproofness, improved the availability factor of filter, prolonged the life of filter.

In order to achieve the above object, the technical scheme of the utility model is to design a car oil filter's thread cover plate structure, including the thread cover plate and the sealing washer fixed plate of mutually supporting, be equipped with cyclic annular seal groove on the sealing washer fixed plate, be equipped with the structure that is used for increasing sealing performance in the seal groove, be equipped with the sealing washer with the seal groove adaptation.

The further technical scheme is that the shape of the sealing groove is a circular groove, the structure for improving the sealing performance is a convex rib arranged in the sealing groove, and the convex rib is arranged on the bottom wall of the groove and is integrally formed with the sealing ring fixing plate. Because the bottom wall of the sealing groove is provided with the convex rib, the sealing is tighter, and the sealing performance of the oil inlet hole of the filter is improved.

The further technical proposal is that the convex rib is annular. Like this whole protruding muscle is as an organic whole form, and it is protruding to the sealing washer in the groove diapire, even appear vibrating because the place of revealing can hardly appear in the setting sealing washer of protruding muscle. Even on the basis, the groove side wall can be provided with a convex rib, so that the tightness of sealing is further ensured.

The further technical proposal is that the convex rib is formed by a plurality of arc-shaped convex rib sections which are discontinuous, and a space is arranged between the adjacent convex rib sections; the end surface of the sealing ring facing the bottom wall of the groove is provided with a groove matched with the convex rib. All the convex ribs are distributed on a circle; the convex ribs are arranged in an non-integrated mode and are arranged in an intermittent split mode, the deformation of the whole sealing ring is small during vibration, and the problem that the sealing ring is not tight due to large deformation of the integrated sealing ring during vibration is solved (the end face, facing the groove bottom wall, of the sealing ring can be also not provided with a groove).

The sealing ring is characterized in that a structure for improving the sealing performance is a blind hole arranged on the bottom wall of the sealing groove, and a bulge matched with the blind hole is arranged on the end face, facing the bottom wall of the sealing groove, of the sealing ring; the blind hole is a circular hole, and the bulge is annular. The blind holes can also be arranged into a plurality of arc blind holes which are intermittently arranged at intervals, and the bulges are intermittently arranged at intervals.

The utility model has the advantages and the beneficial effects that: the sealing performance of the sealing ring on the sealing ring fixing plate is improved by arranging the convex rib in the original sealing groove, the sealing performance of the oil inlet hole of the filter is improved, the problem of poor sealing performance is solved, the service efficiency of the filter is improved, and the service life of the filter is prolonged; whole protruding muscle is the form as an organic whole, and it is protruding to the sealing washer in the groove diapire, even appear vibrating because the place of revealing can hardly appear in the setting sealing washer of protruding muscle. The convex ribs are not integrally arranged and are arranged into an intermittent split type, the deformation of the whole sealing ring is small during vibration, and the problem that the sealing ring is not tight due to large deformation of the integral sealing ring during vibration is solved.
