Description

Quick release structure of bicycle hub

technical field

The utility model relates to a quick dismantling structure of a bicycle flower hub, which provides a wheel body that can be locked on the front and rear forks of the bicycle, so that the wheel body can be removed when the bicycle is carried or placed, so as to reduce the The volume of the bicycle, when using the bicycle for riding, can lock the wheel body to the front and rear forks.

Background technique

The front and rear forks of its bicycle are combined with a wheel body. The wheel body is a combination of an arbor and a flower hub. Then lock it with nuts so that the wheel body can be fixed at the front and rear forks. However, this combination method cannot separate the frame and wheel body of the bicycle in a simple way, so a quick release structure will be used to replace the nut. The lock is set so that the frame and the wheel body can be easily separated, and the quick release is also attached to the mandrel of the hub. Between the frame forks 30, a perforation 21 is formed through the center of the mandrel 20, and a quick release group 40 is provided through the through hole 21. The quick release group 40 is a screw rod 41 combined with a locking head 42, 43 at both ends. Each is formed with a spring 420, 430. One end of the screw rod 41 is provided with a screw head 411, and the screw head 411 can rotate in conjunction with the tool A. A locking head 42 is passed through the screw head 411. The other end is provided with a threaded section 412 , and the threaded section 412 is screwed by another locking head 43 , and the locking head 43 can cooperate with another tool B to rotate or be fixed.

With the use of the quick release group 40, after the screw rod 41 of the quick release group 40 passes through the perforation 21 of the mandrel 20, the locking heads 42 and 43 respectively combined at both ends are frame forks located on both sides of the hub 10. On the outer side of the part 30, the two ends are fixed and rotated with the screw head 411 and the locking head 43 of the screw rod 41 respectively with tools A and B respectively, and the hub 10 and the mandrel 20 are locked to the vehicle frame with the locking heads 42 and 43 30 forks.

In the combination of this kind of mode, when the quick release group 40 is locked or loosened, the two ends must be fixed and rotated by the screw head 411 and the locking head 43 of the screw rod 41 respectively with the tools A and B respectively, so as to be able to be fixed and rotated with one end Tool A, B rotates, and this kind must use the mode of two kinds of tools A, B at the same time, relative to the second hand that one hand is screwed, and the other hand is fixed to use at the same time, the design of structure uses locking or unloading, all has its inconvenience.

In view of this, the creator thought and created the idea, then designed it with many years of experience, after many discussions and sample tests, and many revisions and improvements, the utility model was released.
