[0016] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.
[0017] As shown in Figures 1-3, an anti-falling bolt includes a bolt rod 10 and a bolt head 11, and the bolt head 11 is fixed to one end of the bolt rod 10, characterized in that: the outer peripheral side of the bolt rod 10 is provided with a thread, and the other part of the bolt rod 10 is provided with at least two cardboard cavities 13, and a snap assembly is provided in the cardboard cavity 13, and the snap assembly includes a cardboard 12 rotating in the cardboard cavity 13, and the cardboard 12 is rotatably connected in the cardboard cavity 13 through a rotating shaft 14, and a torsion spring is mounted on the rotating shaft 14, which can keep the cardboard 12 in the cardboard cavity 13 at one end away from the bolt head 11 under normal circumstances. A gathering block 15 is movably provided in the bolt head 11, and the gathering block 15 can be a magnet, that is, the gathering block 15 can be strongly magnetically attracted to be used for disassembling the bolt, and a groove can be opened in the gathering block 15 to facilitate pulling apart the gathering block 15 and disassembling the bolt, and the gathering block 15 is set with an opening on the side close to the bolt rod 10, and one side of the cardboard 12 is clamped through the opening, so that the other side of the cardboard 12 is clamped to the wheel hub.
[0018] A slide groove 17 is provided at the top of the bolt head 11, and the slide groove 17 is connected to the card plate cavity 13. The gathering block 15 is located in the slide groove 17. A gathering groove 18 is provided in the gathering block 15. The gathering block 15 and the bottom of the slide groove 17 are installed together through a spring 19. A main limiting ring 20 is fixed on the inner wall of the gathering groove 18. At least two clamping edges 16 are provided on the end face of one side of the card plate 12. A secondary limiting ring 21 is fixed on the side of the card plate 12 away from the clamping edge 16. The material of the clamping edge 16, the main limiting ring 20 and the secondary limiting ring 21 is one of rubber and resin.
[0019] When in use, the bolt rod 10 can be screwed, and its upper part is a smooth part. When the bolt rod 10 is gradually inserted into the screw hole, the screw hole will abut the clamping plate 12, so that the end of the clamping plate 12 close to the bolt head 11 rotates in the direction of the center line of the bolt rod 10. At the same time, the other end of the clamping plate 12 will gradually abut against the thread in the screw hole, and then be clamped in the thread through the clamping edge 16. Then, the gathering block 15 is pressed down to compress the spring 19, clamp the clamping plate 12, and the mutual limitation of the auxiliary limiting ring 21 and the main limiting ring 20 can avoid the spring 19 from rebounding. At the same time, the pressure of the clamping edge 16 on the clamping plate 12 will be increased, making it clamped on the thread more tightly, effectively avoiding the phenomenon of the thread falling off due to vibration.
[0020] When removing the bolts, it is necessary to pull the gathering block 15 upwards, and make the secondary limiting ring 21 fall off the main limiting ring 20 by means of magnetic attraction or pulling holes, and then the pressure of the edge 16 on the clamping plate 12 is reduced. When the screwed bolts are removed, it can be avoided that the edge 16 is damaged due to the screwing of the bolts when there is pressure on the edge 16.
[0021] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
