Description

Technical Field

[0001] The utility model belongs to the technical field of spokes, and in particular relates to an integrally formed spoke that prevents external separation. Background Art

[0002] Spokes are supporting components installed between the axle and the rim of the wheel. Spokes are used to maintain the same radial spacing at any position in the gap between the axle and the rim, so that the axle remains at the center of the circle, thus forming a complete spoke wheel frame. This type of wheel is commonly used on various bicycle wheels.

[0003] The space between the symmetrical step sections on the left and right sides of the spoke and the inner wall of the sleeve is narrow, and it is difficult for glue to stay between the step sections and the inner wall of the sleeve, which makes it easy for the glue to overflow and makes it inconvenient to inject glue into the inner wall of the sleeve, resulting in loose bonding of the sleeve on the left and right sides of the spoke, making it difficult to assemble the sleeve. The centrifugal force generated by the rotation of the wheel will swing the spokes outward, and the sleeve will easily loosen from the left and right ends of the spokes, which can easily cause the wheel to collapse.

The guide groove can guide the glue from the inside of the straight glue injection groove to the inside of the assembly groove. The glue is fully in contact with the arched elastic plug inside the assembly groove. The arched elastic plug is reinforced and connected with the inside of the adjacent assembly groove by glue. The arched elastic plug limits the sleeve on the left and right sides of the strip body. The glue flows from the inside of the assembly groove to the inside of the annular groove, so that the glue is evenly applied to the inner wall of the sleeve. The sleeve is bonded and connected to the left and right sides of the strip body by glue, so as to achieve the effect of reinforcing the sleeve on the left and right sides of the strip body;
