FIG. 3 is a cross-sectional view of FIG. 2 taken about A-A;

FIG. 4 is a schematic structural view of the mud plate support of the present invention;

FIG. 5 is a schematic structural view of the mud plate of the present invention;

fig. 6 is a partially enlarged view of fig. 5 about C.

The specific implementation mode is as follows:

in an embodiment, as shown in fig. 1 to 6, an angle-adjustable bicycle mudguard comprises a mudguard support 1 and a mudguard 2 fixed below a saddle support rod, wherein the mudguard support 1 comprises a support arm 11 in a U shape, two ends of the support arm 11 are respectively fixed with an adjusting base 12, a counter bore 13 with an opening on the outer side of the adjusting base 12 is formed, and a plurality of convex teeth 14 which are uniformly distributed on the circumference are formed on the bottom surface of the counter bore 13;

the mud plate 2 comprises two support plates 21 which are symmetrically arranged front and back, a boss 22 matched with the counter bore 13 is fixed on the inner side wall of each support plate 21, and a plurality of grooves 23 which are uniformly distributed on the circumference and matched with the convex teeth 14 are formed on the boss 22; the boss 22 is inserted in the counterbore 13 and the teeth 14 are inserted in the grooves 23.

Furthermore, a first chamfer 15 is formed on the convex tooth 14, and a second chamfer 24 is formed at two openings of the groove 23.

Furthermore, a bolt through hole 16 is formed on the bottom surface of the counter bore 13; a hexagonal counterbore 25 is formed on the support plate 21 at the front side, a bolt through hole 26 is formed on the bottom surface of the hexagonal counterbore 25, and a step through hole 27 with a large outer part and a small inner part is formed on the support plate 21 at the rear side; a hexagonal head screw 31 is sleeved in the bolt through hole 26, a hexagonal head of the hexagonal head screw 31 is inserted in the hexagonal counterbore 25, and a screw part of the hexagonal head screw 31 sequentially penetrates through the bolt through holes 16 on the two adjusting bases 12 and an extending end of the step through hole 27 to be screwed with the locking nut 32.

More specifically, the lock nut 32 is a wing nut.

Further, a disc spring 33 is held between the lock nut 32 and the stepped surface of the stepped through hole 27.

The working principle is as follows: when the angle of the mud plate needs to be adjusted, the nut 32 is locked, the support plate 21 of the mud plate 2 is rotated forcibly, the support plate 21 drives the groove 23 on the boss 22 to rotate and slide on the convex tooth 14 on the adjusting base 12 (at this time, the two support plates 21 are opened outwards by a certain angle); the angle of the mud plate 2 can be adjusted by rotating the support plate 21, so that the distance between the mud plate and the wheel is adjusted; after the angle is adjusted, the convex teeth 14 are inserted into the grooves 23 again, so that a new included angle is formed between the mud plate 2 and the mud plate bracket 1, and the locking nut is screwed by the spring to prevent the mud plate 2 from freely rotating on the mud plate bracket 1.

Finally, the above embodiments are only used for illustrating the present invention, and not for limiting the present invention, and those skilled in the relevant art can make various changes and modifications without departing from the spirit and scope of the present invention, so that all equivalent technical solutions also belong to the scope of the present invention, and the protection scope of the present invention should be defined by the claims.
