The foregoing description of the components of the quick release structure 100 for a bicycle according to a preferred embodiment of the present utility model is followed by the following description of the assembly method and the usage characteristics thereof:
when a wheel is to be coupled to a fork (not shown) of a vehicle frame using the present utility model, the quick end cap 60 is separated from the axle 10, the axle 10 is threaded into the wheel and fork, the wrench unit 50 is in a released position (approximately parallel to the axle), the quick end cap 60 is then moved toward the second end 12 of the axle 10, the outer surface of the second end 12 contacts the bead 62, and the bead 62 is pushed outward, so that the bead 62 is pushed onto the inclined surface 631 (as shown in fig. 4), and the outer cap 63 is pushed axially outward until the bead 62 falls into the annular groove 15 of the axle 10, and the outer cap 63 is pulled back by the spring 64 due to the inward movement of the bead 62, so that the boss 632 is pressed against the outer side of the bead 62 (as shown in fig. 5), thereby preventing the quick end cap 60 from being self-propelled with the axle 10, so that the quick end cap 60 is not required to be coupled to the axle 10, which is extremely quickly rotated.
Then, the wrench rod unit 50 is turned to a pressing position (approximately perpendicular to the shaft rod) with the eccentric rod 51 facing upwards, and the swivel 32 of the fine adjustment unit 30 is rotated slightly to tightly abut the swivel 32 on the outer side of the fork, so that the wheel can be coupled to the fork by the present utility model.
Then, when the wheel is to be separated from the fork of the frame, the outer cover 63 of the quick end cap 60 is directly pulled outwards axially, so that the convex pressing portion 632 of the outer cover 63 is not pressed against the bead 62 any more, but the inclined surface 631 corresponds to the bead 62 (as shown in fig. 6), so that the shaft rod 10 can be pulled away directly, the bead 62 is pushed by the shaft rod 10 towards the inclined surface 631, and the bead 62 can be separated from the annular groove 15 (as shown in fig. 7), thereby separating the quick end cap 60 from the shaft rod 10, and achieving the effect of separating the wheel from the fork.
Therefore, the quick end cover 60 of the present utility model can be combined with the shaft rod 10 very quickly and easily (the quick end cover 60 can be pushed into the second end 12 of the shaft rod 10) and can be separated from the shaft rod 10 easily (the outer cover of the quick end cover 60 is pulled first and then the shaft rod 10 is pulled reversely), so that the time and the procedure required for assembling and disassembling the wheel can be reduced greatly and the assembly and disassembly operation of the wheel can be faster.
In addition, since the fine adjustment unit 30 is used to carry out final tightening on the fork body, the eccentric rod body 51 of the wrench rod unit 50 can be turned to the tightening position in a slightly tightened state, and the wrench part 512 of the eccentric rod body 51 faces upwards, so that the impact of foreign matters on the road is avoided, the possibility of self-loosening is reduced, and the effect of improving safety is further achieved.
The present utility model is not limited to the preferred embodiments, and those skilled in the art will appreciate that the present utility model is capable of modification in light of the above-described details.
