They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0021] According to an embodiment of the utility model, a vehicle oil drain screw is provided.

[0022] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-Figure 4 As shown, the automobile oil drain screw according to the embodiment of the utility model includes an oil drain screw body 1, a gasket 2 is sleeved on the circumferential outer side of the oil drain screw body 1, the gasket is connected to the oil drain screw body 1 through a clamping assembly 3, and a pressure ring 4 is arranged at the bottom of the gasket 2.

[0023] With the aid of the above scheme, the automobile oil drain screw provided by the utility model consists of a screw head 101 and a screw rod 102, and by sleeved with a gasket 2 and a pressure ring 4 on the circumferential outer side of the oil drain screw body 1, the direct contact of the oil drain screw body 1 can be reduced, and wear can be reduced, thereby extending the service life of the oil drain screw body 1, and the screw rod 102 is divided into a non-threaded portion 1021 and a threaded portion 1022, so that the overall structure of the screw is more stable, and the threaded portion is located at the bottom end, ensuring an effective connection with the oil pan.

[0024] In one embodiment, for the above-mentioned oil drain screw body 1, the oil drain screw body 1 is composed of a screwing head 101 and a screw rod 102, the screwing head 101 is arranged at the top of the screw rod 102, and a screwing groove 103 is opened on the inner side of the circumference of the screwing head 101, and the screwing groove 103 is a hexagonal structure, and the outer side of the circumference of the screwing head 101 is evenly opened with a dial groove 1011, the screw rod 102 is composed of a non-threaded part 1021 and a threaded part 1022, and the threaded part 1022 is arranged at the bottom end of the non-threaded part 1021, so that by arranging a gasket 2 and a pressure ring 4 on the outer side of the circumference of the oil drain screw body 1, the direct contact of the oil drain screw body 1 can be reduced, the wear is reduced, and the service life of the oil drain screw body 1 is extended, and the screw rod 102 is divided into a non-threaded part 1021 and a threaded part 1022, so that the overall structure of the screw is more stable, and the threaded part is located at the bottom to ensure effective connection with the oil pan.

[0025] In one embodiment, for the above-mentioned clamping assembly 3, the clamping assembly 3 includes a plurality of clamping grooves 301 opened inside the screwing head 101, a plurality of clamping blocks 302 connected to the top of the gasket 2 are arranged inside the clamping groove 301, a compression spring 303 matched with the clamping block 302 is arranged at the inner top of the clamping groove 301, and a compression plate 304 is arranged at the bottom end of the compression spring 303.
