[0020] Such as Figures 1 to 7As shown in the figure, a sealed and waterproof fastening component includes a hexagonal nut main body structure 1 whose projection in the left-right direction is a regular hexagon. A cylindrical sealed fastening and mating connection column 2 is integrally formed at the center position on the left side of the hexagonal nut main body structure 1. They form the overall structure of the mating component. When installed, the inner and outer sides of the sealed fastening and mating connection column 2 can be mated with a sealing ring for double-sealed mating connection. A fastening connection threaded hole 3 that penetrates the left side of the whole is provided on the right side of the hexagonal nut main body structure 1, which can be mated and connected with a threaded column at the installation position. A conical mating guiding and avoiding groove 4 is provided on the right side of the fastening connection threaded hole 3. A cylindrical mating stopping and sealing groove 5 is provided inside the mating guiding and avoiding groove 4. At this position, mating with a sealing ring can achieve a sealed mating connection. Sealed waterproof mating grooves 6 that are circumferentially and evenly distributed and penetrate the inside of the fastening connection threaded hole 3 and the outside of the sealed fastening and mating connection column 2 are provided on the left side of the sealed fastening and mating connection column 2. When assembling, the sealing rings on the inner and outer sides can be firmly pressed into this position during the fastening process. First sealing limit grooves 7 and second sealing limit grooves 8 that are distributed in an inner-outer staggered manner are respectively provided on both sides in the width direction of the sealed waterproof mating groove 6. The sealing ring pressed into the inside can have reliable anti-loosening and waterproof properties. The staggered distribution structure makes the sealed waterproof effect on the inner and outer sides more reliable during the press-fitting process, and can meet the fastening mating requirements in an application environment with a relatively high humidity. The depths of the first sealing limit groove 7 and the second sealing limit groove 8 are the same as the length of the sealed fastening and mating connection column 2, which is more convenient for production and processing and has better structural stability. When in use, through the combined use of multiple sealing rings on the inner and outer sides at both ends, it can achieve the combined effect of multiple seals at different positions. And with the setting of the sealing limit grooves, the sealing rings can be pressed into the internal limit structure during mating, making the overall sealed waterproof performance better during use, meeting the safe use requirements in an application environment with a relatively high humidity, being more convenient to operate during the fastening mating process, having better safety during later use, and being more reliable in durability.
[0021] Preferably, the depth of the sealed waterproof mating groove 6 is the same as the length of the sealed fastening and mating connection column 2, making the overall structural support strength better and the service life longer during use.
[0022] Preferably, the cross-sections of the first sealing limit groove 7 and the second sealing limit groove 8 are both arc-shaped structures, which are more convenient for production and processing and have higher production efficiency.
[0023] Preferably, the width of the outer side positions of the first sealing limit groove 7 and the second sealing limit groove 8 is greater than the width of the inner side positions. When mating, it can be more smoothly pressed together with the sealing ring. If a rectangular-like structure is adopted, the smoothness during pressing will be relatively poor.
[0024] Preferably, a mating guiding fillet structure for facilitating combination is provided at the outer edge positions of the first sealing limiting groove 7 and the second sealing limiting groove 8. It is more convenient during assembly and combination, has the function of mating guidance, can improve the mating efficiency during combination, and further improve the smoothness when the sealing ring is press-fitted.
[0025] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements or substitutions can be made, and these improvements or substitutions should also be regarded as the protection scope of the present invention.
