Detailed implementation manners
[0021] Such as Figures 1 to 8As shown in the figure, a sealed fastener includes a cylindrical main body connecting and fitting column 1. An integrally formed mounting stop and stabilizing column 2 is provided on the right side of the main body connecting and fitting column 1. An overall fastening thread groove is provided on the outer cylindrical surface of the main body connecting and fitting column 1. A cylindrical combined sealing and stabilizing groove 3 is provided on the left side of the main body connecting and fitting column 1, which can enable a more stable sealing fit for the fitting structure at the internal position during fitting. A tapered transition fitting connection groove 4 is provided on the right side of the combined sealing and stabilizing groove 3, and a gasket can be fitted for internal combined connection at this position according to needs. A cylindrical second combined fastening hole 5 is provided on the right side of the transition fitting connection groove 4. A second combined thread groove is provided on the inner cylindrical surface of the second combined fastening hole 5, and inner-side fastening connection can be achieved through this position. A sealing combined groove is provided at the central position on the right side of the mounting stop and stabilizing column 2. A sealing and anti-loosening fitting seat 6 is placed in the sealing combined groove. It can achieve an interlocking connection with the structure on the right side during internal fitting, making the overall fastening more firm. A conical combined sealing fitting groove 7 is provided on the left side of the sealing and anti-loosening fitting seat 6, which communicates with the second combined fastening hole 5. Combined pressing and deformation grooves 8 that penetrate the outside of the sealing and anti-loosening fitting seat 6 and are evenly distributed in a circumferential manner are provided on the outside of the combined sealing fitting groove 7. Pressing deformation can be achieved during the fastening process, so as to achieve the effect of preventing loosening of the fitting at the fastening position. A cylindrical central fitting connection hole 9 is provided at the central axis position of the sealing and anti-loosening fitting seat 6. A conical sealing combined fitting groove is formed between the outside of the sealing and anti-loosening fitting seat 6 and the mounting stop and stabilizing column 2, and a sealing ring can be fitted for sealing assembly at this position, making the sealing stability at the connection position more reliable. When in use, double fastening and fitting connection can be carried out through the inner and outer fastening structures. The internal structure has better fitting tightness during installation by setting multiple mutually cooperating combined structures. The right side position is provided with an embedded sealing component, which can ensure reliable sealing after fastening during fitting, and has higher overall safety during the later use process. The overall installation and combination operation is more convenient, which can replace the combined use of multiple existing fasteners, making the combination connection efficiency during assembly higher and the fitting strength at the combination connection position more reliable.
[0022] Preferably, the right end face of the mounting stop and stabilizing column 2 is in the same plane as the right end face of the sealing and anti-loosening fitting seat 6, making the flatness of the structure on the right side better, having a longer service life during use, and better structural stability.
[0023] Preferably, the dimension of the left side position of the combined sealing fitting groove 7 is larger than the dimension of the right side position of the second combined fastening hole 5, providing a larger fitting space during internal combination and making the combination operation more convenient.
[0024] Preferably, the cross-section at the middle position of the transition fit connection groove 4 is an arc-shaped structure, and a sealing waterproof gasket can be fitted and connected at this position as required, with a larger sealing fit area at the fitting position and better fitting tightness.
[0025] Preferably, the depth of the sealing combination groove is greater than the thickness of the installation stop stabilizing column 2, making the structural stability more reliable during the overall combination.
[0026] The above is the preferred embodiment 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.
