Strong magnetic adsorption iron filings oil drain plug

Abstract

The invention discloses an oil drain plug capable of adsorbing iron filings through strong magnetism. The oil drain plug comprises a rod body of which the section is circular, wherein the right end of the rod body and the middle part of the left end face of a nut are connected into an integral body; a magnet core inserting hole is formed the middle part of the right end face of the nut in the left-right horizontal direction; the magnet core inserting hole extends leftwards along the axis of the rod body into the rod body; a screw thread is arranged on the outer surface of the right half part of the rod body; an oil pass hole which penetrates through the side wall of the rod body is formed in the middle part of the left side wall of the rod body in the front-back direction; a compression spring is arranged at the left end of the magnet core inserting hole; the left end of the compression spring is propped against the inner wall of the inner left end of the magnet core inserting hole; the right end of the compression spring is propped against the left end face of a rubber plug; the cross section of the rubber plug is circular; and a circumferential surface of the rubber plug is mounted on the left side in the magnet core inserting hole through clearance fit. According to the oil drain plug capable of adsorbing iron filings through strong magnetism provided by the invention, the structure is simple, the utilization is convenient, a magnet core on the oil drain plug can be taken down at any time to remove iron filings on the magnet core, the quality of an oil product is effectively guaranteed, and the service life of related equipment can be prolonged.

Description

technical field [0001] The invention relates to a strong magnetic adsorption iron filings drain plug. Background technique [0002] Most of the existing oil drain plugs do not have the function of absorbing iron filings in the oil, although there are also magnets on the oil drain plug to absorb iron filings in the oil, but due to its unreasonable structural design, the oil cannot be removed at any time. The iron filings adsorbed on the plug can only be removed when the oil needs to be changed. As a result, it cannot remove the adsorbed iron filings in time, resulting in its practicality. Sex is poor. Contents of the invention [0003] The purpose of the present invention is to provide a kind of simple structure, easy to use, can remove the magnetic core on the oil plug at any time to remove the iron filings on it, effectively ensure the quality of oil products, and then can improve the service life of related equipment. Chip drain plug. [0004] The strong magnetic adso...
