Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile accessories, in particular to an oil drain screw with a spiral structure. Background Art
[0002] In the process of changing the oil in a car, the drain screw plays a vital role. The drain screw (also known as the drain bolt or drain plug) is a screw fixed to the engine oil pan, mainly used to control and release the used oil. It is a component that must be opened when changing the oil.
[0003] The oil drain screw is not only used to drain the old oil, but also must ensure that it can effectively seal the oil pan after the new oil is added to prevent oil leakage, which is essential to keep the engine and the environment clean. The oil drain screw is usually made of corrosion-resistant materials such as stainless steel or metal with anti-corrosion coating to resist chemical corrosion and physical wear.
[0004] During the process of changing the car's engine oil, an oil drain screw with an adsorption function is used to capture metal impurities in the oil. By adsorbing these impurities, it helps to reduce this wear and tear, thereby extending the service life of the engine. However, if the metal impurities cannot be effectively adsorbed, the presence of metal impurities in the oil may increase the wear between mechanical parts, especially for those high-precision or high-speed mechanical parts, thereby increasing the frequency of maintenance and replacement of parts.
[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0027] In one embodiment, for the above-mentioned adjustment component 3, the adjustment component 3 includes a mounting hole 301 arranged inside the screw rod 102, a compression spring 302 is arranged at the inner top of the mounting hole 301, a connecting plate 303 is arranged at the bottom end of the compression spring 302, a plurality of connecting blocks 304 are arranged at the outer bottom of the connecting plate 303, an adsorption magnet 4 is arranged at the bottom end of the connecting plate 303, a plurality of arc-shaped protrusions 306 are arranged on the circumferential outer side of the adsorption magnet 4, the connecting plate 303 and the adsorption magnet 4 are both arranged inside the fixed cylinder 307, and a mounting groove 305 matched with the arc-shaped protrusion 306 is opened on the outer side of the fixed cylinder 307, so as to enhance the sealing performance of the oil drain screw, effectively prevent oil leakage, and keep the equipment clean and operating normally; under the cooperation of the adjustment component 3 and the adsorption magnet 4, the utility model can adjust the position of the adsorption magnet 4 to adsorb metal impurities in the engine oil, thereby effectively reducing the deposition of impurities, thereby reducing the damage of metal impurities to mechanical parts, and reducing the frequency of maintenance and replacement of parts.
