[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] See also Figure 1-3 , the utility model provides the following technical solutions:

[0027] A drilling bolt and nut assembly for automobile accessories, comprising:

[0028] A bolt cover 1, the lower end of which is fixedly connected with a bolt 7;

[0029] A nut 8, the nut 8 being threadedly connected to a circumferential surface of the bolt 7;

[0030] A rotating ring 9, which is rotatably connected to the outer side of the nut 8; and

[0031] Two sets of tightening mechanisms, each set of tightening mechanisms consists of a mounting block 2, a connecting plate 3, a connecting rod 4, a plurality of docking grooves 5, a connecting groove, a placement groove 13, a spring 14, a push rod 11 and a docking bead 12. The mounting block 2 and the connecting plate 3 are respectively fixedly connected to one end of the bolt cover 1 and the circumferential surface of the rotating ring 9. The connecting groove is opened at the upper end of the connecting plate 3, the connecting rod 4 is fixedly connected to the lower end of the mounting block 2, a plurality of docking grooves 5 are opened at one end of the connecting rod 4, the placement groove 13 is opened on one side inner wall of the connecting groove, the spring 14 is fixedly connected to one side inner wall of the placement groove 13, the push rod 11 is fixedly connected to one end of the spring 14, the docking bead 12 is fixedly connected to one end of the push rod 11, and the docking bead 12 matches the docking groove 5.

[0032] In a specific embodiment of the utility model, when the nut 8 is connected to the circumferential surface of the bolt 7 through a thread and is gradually tightened, the rotating ring 9 will be driven to move by the nut 8, and the connecting plate 3 will also move on the outer surface of the connecting rod 4 through the connecting groove. By elastic expansion of the spring 14 fixedly connected to the inner wall of one side of the placement groove 13, the push rod 11 can be pushed to the left, and the docking bead 12 and the docking groove 5 can be pushed to cooperate and connect. When the thread cooperation between the nut 8 and the bolt 7 fails, the cooperation between the docking bead 12 and the docking groove 5 can compensate for the failed part of the thread, so that the nut 8 and the bolt 7 always maintain a suitable and stable connection force.

[0033] For details, please refer to Figure 2 A telescopic rod 15 is fixedly connected to the inner wall of one side of the placement groove 13, and a spring 14 is sleeved on the circumferential surface of the telescopic rod 15. An I-shaped groove 10 is opened on the circumferential surface of the nut 8, and the rotating ring 9 is rotatably connected in the I-shaped groove 10. A rotating groove 6 is opened at the upper end of the bolt cover 1, and the rotating groove 6 is cross-shaped. The docking groove 5 and the docking bead 12 are both bead-shaped. The length of the connecting rod 4 should be consistent with the length of the bolt 7.

[0034] In this embodiment: the telescopic rod 15 can prevent the spring 14 from bending and deforming to cause damage. When the nut 8 moves, the rotating ring 9 can be rotated through the I-slot 10, so that the nut 8 will not affect the vertical movement of the rotating ring 9 when it rotates and moves. The rotating groove 6 can facilitate the rotation of the bolt cover 1 by a screwdriver or the like.

[0035] The working principle and use process of the utility model are as follows: when the nut 8 is connected to the circumferential surface of the bolt 7 through threads and is gradually tightened, the rotating ring 9 will be driven to move by the nut 8, and the connecting plate 3 will also move on the outer surface of the connecting rod 4 through the connecting groove. By elastic expansion of the spring 14 fixedly connected to the inner wall of one side of the placement groove 13, the push rod 11 can be pushed to the left, and the docking bead 12 and the docking groove 5 can be pushed to cooperate and connect. When the thread cooperation between the nut 8 and the bolt 7 fails, the cooperation between the docking bead 12 and the docking groove 5 can compensate for the failed part of the thread, so that the nut 8 and the bolt 7 always maintain a suitable and stable connection force.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
