Detailed Embodiment
[0020] Such as Figures 1 to 7As shown in the figure, a sealing and pressing type fastening component includes a cylindrical main body pressing and fitting column 1 with its central axis in the front-rear direction. A through main body assembly and connection hole 3 is provided at the central axis position of the main body pressing and fitting column 1. This position can meet the combined placement when cylindrical components are spliced and fitted, and can also be sleeved together with a single cylindrical component. A fastening and fitting movable deformation groove with an opening to the left is provided on the left side of the main body assembly and connection hole 3 to ensure more space during installation. A horizontally leftward support and stable connection plate 2 is provided at the lower end position of the fastening and fitting movable deformation groove. An integrally formed and inclined upward leftward pressing and fitting movable plate 4 is provided at the upper end of the fastening and fitting movable deformation groove, which can move downward and deform during use for overall pressing and fitting. An arc-shaped sealing and fitting combined column 5 with an opening upward is provided at the upper end of the support and stable connection plate 2. A cylindrical fastening, connecting and sealing column 6 is integrally formed at the right side position of the pressing and fitting movable plate 4. When the fastening, connecting and sealing column 6 presses downward and fits, it can be combined and connected with the fitting groove on the sealing and fitting combined column 5, which can ensure the combined sealing performance of the pressing and fitting position and also ensure better connection safety at the fitting position. A combined positioning and fitting hole 7 is provided on the support and stable connection plate 2, which can be used for overall preliminary fastening and installation to fix the overall position. A pressing and fitting connection hole 8 is provided on the pressing and fitting movable plate 4.
