Description of the Invention: [Technical Field] The present invention relates to a sprocket structure, in particular to a reinforced sprocket structure for a bicycle sprocket, and utilizes a single-axis, single-sided, single-setting mode. The sprocket is combined into a key wheel set to increase the overall strength of the sprocket set. [Previous technology] According to Taiwan, Taiwan is the world's largest bicycle manufacturing country. Taiwan's high-quality bicycles are more praised by the world. Because the Chinese people began to pay attention to leisure activities on the 2nd week of the week, the government and private organizations promote bicycle activities, so bicycles are The domestic trend is that the bicycle is not only a means of transportation, but also a kind of competition. Under the rigorous test of speed and time, the bicycle design is developing in the direction of light weight and high strength, but the intensity is often The weight is proportional to 'how to balance the high-intensity miscellaneous... It is the subject of the bicycle industry to be solved. Under the circumstance of cycling and industry development, various ergonomic designs, high-strength structures and light Quantified bicycles have also been asked about the market. For a bicycle sprocket structure, please refer to the "Sprocket support member f〇ra bicycle sprocket assembly" of the US Patent No. 7131656. A bicycle sprocket structure includes at least one component, and the sub-assembly includes a key wheel slab component and The two sprocket wheels, the sprocket support member includes at least one engaging portion and a locking portion for coupling with the bicycle flywheel, the solid portion is radially outwardly extended by the spray portion, and the two-key wheel train And the key wheel support member is fixed on both sides of the concentric portion of the lock portion. The conventional bicycle sprocket needs to use the sprocket support element to lock the sprocket, and then combine with the bicycle flywheel, or the single-piece sprocket is combined with the bicycle flywheel; through the above, the custom 1338655 custom key wheel structure is known. _The locking part is flushed with the same - to the sides; however n. & ~ ton wheel fixed when the sprocket support component is quite large, because Γ heavy fixed, the _ department structure produces a healthy gear. Her lake class 'b- 彡 彡 _ bears two phases for double self, and tear _ The system will produce a powerful force. When the single-axis long-term and double-key rounds are connected, it is easy to cause structural fatigue. What are the problems with the above-mentioned bicycle sprocket structure?
