For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0021] The following is combined with Figure 1-3 This application is described in further detail.

[0022] The present application discloses a waterproof screw for connecting electronic products. Figure 1 , including a screw body 1, a gasket 2 and a cover 3. It can be understood that the screw body 1 is used to connect and fix electronic products, the gasket 2 is used to increase the contact area between the screw body 1 and the electronic product, reduce pressure and prevent loosening, and the cover 3 is used to improve the sealing between the screw body 1 and the gasket 2.

[0023] See also Figure 2 It should be noted that the screw body 1 includes a head 11, an extrusion portion 12 and a threaded portion 13 sequentially distributed from top to bottom. The head 11, the extrusion portion 12 and the threaded portion 13 are integrally formed. The extrusion portion 12 is configured to be tapered with a width at the top and a narrowness at the bottom, so that it has a gradual extrusion effect. The end of the threaded portion 13 away from the head 11 is configured to be a smooth semi-elliptical shape to prevent the threaded portion 13 from accidentally pricking the hand during use of the screw; it should be further noted that the gasket 2 includes a ring body 21 and a cover body 22 sequentially distributed from top to bottom. The ring body 21 and the cover body 22 It is integrally formed, and the same rubber block 23 is embedded in the inner side of the ring body 21 and the cover body 22. When the downward extrusion part 12 completely squeezes the rubber block 23, the rubber block 23 tightly fills the inside of the ring body 21 and the cover body 22 to avoid gaps between the cover body 22 and the electronic product, thereby enhancing the sealing and waterproof effect of the screw; in order to improve the strength of the cover body 22, the cover body 22 is set to be arc-shaped. It can be understood that the outer diameter of the cover body 22 is larger than the outer diameter of the ring body 21, and the blocking cover 3 is threadedly sleeved on the outer side of the ring body 21, and the outer side of the blocking cover 3 is provided with anti-slip grooves.

[0024] Please combine Figure 2 and Figure 3 It should be noted that the rubber block 23 includes an integrally formed first filling portion 231 and a second filling portion 232. The first filling portion 231 is located on the inner side of the ring body 21, and the second filling portion 232 is located on the inner side of the cover body 22. A vertical through-hole is provided on the first filling portion 231 and the second filling portion 232, and the aperture of the reserved hole is larger than the diameter of the threaded portion 13. When using a screw, the threaded portion 13 and the extrusion portion 12 pass through the reserved hole in sequence.

[0025] The implementation principle of the waterproof screw for connecting electronic products in the embodiment of the present application is as follows: when using the screw, first, the rubber block 23 needs to be embedded in the inside of the ring body 21 and the cover body 22 until the first filling part 231 and the second filling part 232 are respectively attached to the ring body 21 and the cover body 22. Then, the threaded part 13 can be passed through the reserved holes of the first filling part 231 and the second filling part 232 by pinching the head 11, and the threaded part 13 can be inserted into the connection hole of the electronic product. The screw body 1 is tightened by using relevant tools until the head 11 is attached to the cover body 22. The ring body 21 is tightly pressed against each other to connect and fix the electronic product. During this process, the downward-moving extrusion part 12 gradually squeezes the first filling part 231 and the second filling part 232, causing the first filling part 231 and the second filling part 232 to deform, thereby tightly filling the ring body 21 and the cover body 22 respectively to avoid gaps between the cover body 22 and the electronic product, thereby enhancing the sealing and waterproof effect of the screw. Finally, the blocking cover 3 can be put on the ring body 21 and tightened to improve the sealing between the screw body 1 and the gasket 2.

[0026] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
