A wedge-shaped head is provided at one end of the spoke and is inserted into the wedge groove. The other end of the spoke is installed with a tire. A limiting component is slidably sleeved on the spoke.

[0007] Furthermore, in a preferred configuration, slots are provided on both sides of the inner wall of the wedge-shaped groove.

[0008] In addition, a preferred structure is that the spoke discs at both ends of the hub are provided with several sets of connecting grooves, and hook grooves are provided inside the connecting grooves.

[0009] In addition, a preferred structure is that elastic blocks are provided on both sides of the wedge head, and the elastic blocks are engaged in the slots.

[0010] In addition, a preferred structure is that the limiting component includes a limiting baffle with a sliding hole, and the limiting baffle is slidably sleeved on the spoke through the sliding hole.

[0011] In addition, a preferred structure is that both ends of the bottom of the limiting baffle are provided with connecting plates, and hooks are provided on the inner side of the connecting plates. The connecting plates are slidably inserted into the connecting grooves, and the hooks are engaged in the hook grooves.

[0012] The beneficial effects of this utility model are as follows:

[0013] In this invention, the wedge-shaped head of the spoke is inserted into the wedge-shaped groove, and then the hook is deformed in the connecting groove and locked into the hook groove. At this time, the limiting component limits the spoke, and the spoke can be installed on the hub without special tools, which is extremely convenient. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-6 A spoke and hub connection structure includes a hub 1 and spokes 2. Several wedge-shaped grooves 11 are provided on the spoke discs at both ends of the hub 1. A wedge-shaped head 21 is provided at one end of the spoke 2 and is inserted into the wedge groove 11. The other end of the spoke 2 is installed with a tire 3. A limiting component 4 is slidably sleeved on the spoke 2.

[0023] The wedge-shaped groove 11 has slots 111 on both sides of its inner wall.

[0024] Meanwhile, several sets of connecting grooves 12 are provided on the spoke discs at both ends of the hub 1, and hook grooves 121 are provided on the inner side of the connecting grooves 12.

[0025] Furthermore, elastic locking blocks 211 are provided on both sides of the wedge head 21. The elastic locking blocks 211 are locked in the locking groove 111 to initially limit the wedge head 21.

[0026] Meanwhile, the limiting component 4 includes a limiting baffle 41, on which a sliding hole 411 is provided. The limiting baffle 41 is slidably sleeved on the spoke 2 through the sliding hole 411. The limiting baffle 41 can slide on the spoke 2, thereby facilitating the installation of the spoke 2 onto the hub 1.

[0027] Furthermore, both ends of the bottom of the limiting baffle 41 are provided with connecting plates 42, and hooks 43 are provided on the inner side of the connecting plates 42. The connecting plates 42 are slidably inserted into the connecting groove 12, and the hooks 43 are locked in the hook groove 121 to limit the limiting baffle 41. The limiting baffle 41 is firmly attached to the top of the wedge head 21 to limit the wedge head 21 and prevent the spokes 2 from falling off the hub 1.

[0028] In this embodiment, the wedge head 21 of the spoke 2 is aligned with the wedge groove 11 and inserted. At this time, the elastic block 211 undergoes elastic deformation and then the elastic block 211 is engaged in the groove 111, which initially limits the wedge head 21. Then, the limiting component 4 is slid down and the connecting plate 42 of the limiting component 4 is aligned with the connecting groove 12. Then, the two ends of the limiting baffle 41 are pressed down forcefully, so that the hook 43 slides into the connecting groove 12. The hook 43 will deform. Then, the limiting baffle 41 is pressed down further, and the hook 43 will be engaged in the hook groove 121 and return to its original shape. At this time, the limiting baffle 41 can further limit the wedge head 21 and prevent the spoke 2 from falling off the hub 1.

[0029] In this invention, the wedge-shaped head 21 of the spoke 2 is inserted into the wedge-shaped groove 11, and then the hook 43 is deformed in the connecting groove 12 and then locked into the hook groove 121. At this time, the limiting component 4 limits the spoke 2, and the spoke 2 can be installed on the hub 1 without special tools, which is extremely convenient.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
