Therefore, according to the utility model discloses a bolt end cap 1 for vehicle can shelter from the bolt, has improved the aesthetic property of whole car and the reliability of bolt, and has advantages such as simple structure, simple to operate, low cost.

According to the utility model discloses all terrain vehicle, through according to the utility model discloses a bolt end cap 1 for vehicle has advantages such as pleasing to the eye clean and tidy and safe and reliable.

According to some embodiments of the present invention, as shown in fig. 1 to 4, the surface of the expansion plug 200 facing the nut 400 is provided with an anti-rotation groove 210, and the nut 400 is fitted in the anti-rotation groove 210 to prevent the nut 400 from rotating relative to the expansion plug 200. The anti-rotation groove 210 communicates with the second through hole 230, and the anti-rotation groove 210 coincides with the axial center of the second through hole 230.

Further, the nut 400 includes a rotation prevention portion 410 and a stopper piece 420. The rotation preventing portion 410 is fitted in the rotation preventing groove 210, the stopper piece 420 is provided on a surface of the rotation preventing portion 410 facing away from the expansion plug 200, and the stopper piece 420 is stopped on the surface of the expansion plug 200 where the rotation preventing groove 210 is constructed.

Further, the anti-rotation portion 410 and the anti-rotation groove 210 are hexagonal shapes that match each other.

In this way, the anti-twisting connection between the nut 400 and the expansion plug 200 prevents the nut 400 and the expansion plug 200 from being displaced relative to each other in the circumferential direction when the screw 300 is screwed, and thus the screw 300 can be effectively screwed and unscrewed, so as to conveniently and accurately control the expansion state of the expansion plug 200. The rotation preventing portion 410 and the rotation preventing groove 210 are hexagonal shapes matched with each other, the fitting is tight, and the anti-rotation effect is further enhanced, and the stopper piece 420 is provided to improve the stability of the relative positions of the expansion plug 200 and the nut 400 in the axial direction.

Of course, it will be understood by those skilled in the art that the anti-rotation portion 410 and the anti-rotation slot 210 may have other shapes matching each other, as long as the anti-rotation effect is achieved, such as non-circular shape.

According to some embodiments of the present invention, as shown in fig. 1 to 4, the stopper piece 420 has a circular shape, and the outer diameter of the stopper piece 420 is larger than the maximum outer diameter of the rotation preventing part 410. Thus, the stopper piece 420 is further prevented from entering the rotation preventing portion 410 by mistake, and the nut 400 is easily removed from the expansion plug 200.

According to some embodiments of the present invention, as shown in fig. 1-4, the screw 300 is a countersunk head screw, the decorative cover 100 is configured with a tapered portion 110 recessed toward the expansion plug 200, the countersunk head screw passes through the tapered portion 110, and the nut 310 of the screw 300 is engaged with the tapered portion 110. The countersunk head screw may be a cross countersunk head screw. The tapered portion 110 communicates with the first through hole 130.

Further, the surface of the expansion plug 200 facing the trim cover 100 is provided with a tapered depressed groove 220, and the tapered portion 110 is fitted in the tapered depressed groove 220. The tapered sink 220 communicates with the second through-hole 230.

Specifically, the tapered portion 110 coincides with the axial center of the trim cover 100, and the tapered sinking groove 220 coincides with the axial center of the expansion plug 200. Nut 310 mates with cone 110, i.e., nut 310 is embedded in cone 110. The tapered portion 110 fits within the tapered recess 220, i.e., the tapered portion 110 fits into the tapered recess 220. The screw 300 passes through the tapered portion 110 and the tapered sinking groove 220.

Thus, the screw 300 is a countersunk head screw, and the nut 310 of the screw 300 is matched with the conical part 110, so that the aesthetic property of the vehicle is enhanced. The nut 310 of the screw 300 is matched with the conical part 110, the conical part 110 is matched in the conical sinking groove 220, the three are further positioned in the axial direction, the connection stability among the screw 300, the decorative cover 100 and the expansion plug 200 is ensured, the alignment of the decorative cover 100, the expansion plug 200 and the nut 400 can be ensured, and therefore the screw 300 can be conveniently and smoothly penetrated and arranged.

According to some embodiments of the present invention, as shown in fig. 1 to 4, the decoration cover 100 is configured in a spherical crown shape protruding in a direction away from the expansion plug 200, the decoration cover 100 is provided with a plurality of hollow holes 120 arranged at intervals along a circumferential direction thereof, the expansion plug 200 is configured in a cylindrical shape, and an outer diameter of the expansion plug 200 is smaller than an outer diameter of the decoration cover 100.

Specifically, the plurality of hollow holes 120 may be disposed at equal intervals. The outer diameter of the expansion plug 200 may be less than or equal to the outer diameter of the trim cover 100. The cosmetic cover 100 is located at one end of the expansion plug 200 in the longitudinal direction, and the nut 400 is located at the other end of the expansion plug 200 in the longitudinal direction.

Thus, the decorative cover 100 is configured into a spherical cap shape protruding in the direction away from the expansion plug 200, so that passengers can be prevented from being scratched, the safety of the passengers is guaranteed, and the attractiveness of the whole vehicle is improved. Due to the arrangement of the hollow holes 120, the weight of the whole vehicle is reduced, and the attractiveness of the whole vehicle is further improved. The expansion plug 200 is cylindrical, the stress of each part in the circumferential direction of the expansion plug 200 is uniform, the expansion effect is good, the contact position between the expansion plug 200 and the decorative cover 100 is high in fitting degree, and the shielding effect is good. In addition, since the outer diameter of the expansion plug 200 is smaller than that of the decoration cap 100, the decoration cap 100 can completely close the end of the bushing 4 after the expansion plug 200 is fitted into the bushing 4.

Other configurations of atvs according to embodiments of the invention are known to those of ordinary skill in the art and will not be described in detail herein.
