Please refer to FIG. 1 , which shows a rim spoke adjusting fixture provided by the present invention, which comprises a rim 1 , a flower hub 2 and a plurality of spokes 3 , wherein the rim 1 is annular and defined with a The center position C, the hub 2 is disposed at the center position C, and the plurality of spokes 3 are connected between the rim 1 and the hub 2, and the rim 1 is maintained as a perfect circle by the spokes 3 as a support.
In the structure of the detail, as shown in the second and third figures, the flower hub 2 is a cylinder, and a plurality of second connecting holes 21 are respectively formed at the outer edges of the two ends, wherein the second connecting hole 21 is a screw In the present embodiment, a second ridge 22 is disposed in the radial direction of the flower hub 2 corresponding to each of the second connecting holes 21, thereby reinforcing the flower hub 2 in the vicinity of each of the second connecting holes 21. Structural strength.
A screw segment 32 is respectively disposed at each end of each spoke 3, and each spoke 3 is screwed into the second connecting hole 21 of the flower hub 2 by a screw segment 32 at one end thereof. In this embodiment, the two ends of each spoke 3 are respectively fixed with a joint member 31, and the threaded portion 32 is disposed on the circumferential side of the joint member 31. A fixing nut 33 is disposed on the coupling member 31 of each of the spokes 3, wherein the fixing nut 33 is screwed on the threaded portion 32 of the coupling member 31. Here, the fixed joint between the spokes 3 and the flower hub 2 is divided into two stages, as shown in Fig. 3, wherein the first stage is locked to the second connection of the flower hub 2 by the joint 31 of one end of each spoke 3 The hole 21, and then the second stage, is further rotated by the fixing nut 33 so as to approach and urge the second ridge 22 toward the hub 2. Thereby, in addition to the fixing effect that the spokes 3 are locked in the second connecting hole 21 of the flower hub 2, the fixing nut 33 can further strengthen the fixing effect of fixing the spokes 3 to the flower hub 2.
On the other hand, on the detailed structure of the rim 1, as shown in Fig. 1, it is defined that the side of the rim 1 facing the center position C is the inner side 11 and the side facing the center position C is the outer side. 12. With the fourth figure, the rim 1 is provided with a plurality of first connecting holes 13 along the circumference, the number of which corresponds to the number of the second connecting holes of the flower hub; wherein each of the first connecting holes 13 along the rim 1 In the present embodiment, the first ridge 14 is respectively disposed on the inner side 11 of the rim 1 corresponding to each of the first connecting holes 13 to strengthen the rim 1 in each first The structural strength near the connection hole 13.
