Detailed implementation manners

[0019] Such as Figures 1 to 7As shown in the figure, an easily combinable and anti-loosening wheel hub fastening assembly includes a cylindrical main body combined stabilizing column 1 made of stainless steel material. A cylindrical mating stop connecting plate 2 is integrally formed at the lower end of the main body combined stabilizing column 1, which can play a mating stop role during installation and mating. The diameter of the main body combined stabilizing column 1 is smaller than that of the mating stop connecting plate 2. A cylindrical combined sealing connection groove 3 is provided at the upper end of the main body combined stabilizing column 1, which can be embedded and combined with the mating structure at the wheel hub installation position to ensure better tightness during mating. A cylindrical reinforcing combined connection column 4 is integrally formed at the center position of the lower end of the combined sealing connection groove 3, making the strength inside the mating position higher. A cylindrical central mating connection hole 5 that penetrates the entire lower end face is provided at the center position of the upper end of the reinforcing combined connection column 4, which can be mated with the central axis of the wheel hub installation position. Spiral combined fastening mating grooves 6 that are evenly distributed in a circle on the inner cylindrical surface of the combined sealing connection groove 3 and completely penetrate the outside of the whole can be spirally fastened and mated with the positioning structure at the mating position. On the one hand, it ensures more convenient operation during mating, and on the other hand, it enables a larger combined space at the mating position. First fastening connection holes 7 that are evenly distributed in a circle are provided at the outer position of the lower end face of the mating stop connecting plate 2, and second fastening connection holes 8 that are evenly distributed in a circle are provided at the inner position of the lower end face of the mating stop connecting plate 2. By selecting fastening connection holes at different positions for fastening and mating as needed, it can meet the fastening and mating requirements of various different specifications of wheel hub structures. Lubricating mating connection holes 9 that are evenly distributed in a circle and completely penetrate the whole lower end face are provided at the lower end of the combined sealing connection groove 3. According to needs, lubricating fluid can be added for use, and it is more convenient to add lubricating fluid.
