In the drawings, the list of components represented by the various numbers is as follows:

1. a cap head; 2. a plug hole; 3. a mounting part; 4. a connection part; 5. a first pit; 6. a second pit; 7. a spoke rod.

Description of the embodiments

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The present application is described in further detail below in conjunction with figures 1-2.

The utility model provides a combined material spoke, includes cap head 1, spoke stick 7, offers spliced eye 2 on the cap head 1, and spoke stick 7 one end is pegged graft in spliced eye 2, and cap head 1 adopts alloy material to make, and spoke stick 7 includes installation department 3 and connecting portion, and installation department 3 is pegged graft in spliced eye 2, and installation department 3 also adopts the alloy to make. The cap head 1 is provided with a first concave point 5, the spoke 7 is provided with a second concave point 6, and the first concave point 5 is positioned in the second concave point 6.

The first bump and the second bump are obtained through the following steps, wherein the first step is to provide a plug hole 2 on the cap head 1; secondly, inserting one end of a spoke 7 into the inserting hole 2; thirdly, pressing the cap head 1; during pressing, the cap head 1 and the spoke 7 are simultaneously extruded, the cap head 1 and the mounting part 3 are simultaneously deformed, the first concave point 5 is formed on the cap head 1 after pressing, the second concave point 6 is formed on the spoke 7, the first concave point 5 is located in the second concave point 6, and when the spoke 7 moves, the first concave point 5 can abut against the second concave point 6, so that the spoke 7 is prevented from moving. During production, the spoke 7 does not need to be provided with a thread, and the cap head 1 is provided with a threaded hole, so that the process steps are reduced, and the effect of improving the production efficiency is achieved.

The mounting portion 3 made of alloy can reduce the rebound after the mounting portion 3 is pressed, meanwhile, the strength of the mounting portion 3 is improved, the connecting portion 4 is made of carbon fibers, and the connecting portion 4 made of carbon fibers can reduce the weight of the spoke rod 7, so that the effect of the weight of the whole rim is reduced. The first pits 5 are provided in plurality on the cap head 1, and the plurality of first pits 5 can further stabilize the cap head 1 to be mounted on the spoke 7, thereby further stabilizing the first cap head 1.
