[0028] See Figure 1-8 As shown, as an embodiment of the present invention, a wheel rim assembly with anti-rotation spokes is provided, including a spoke 1, a first connecting member 2 is fixedly installed at one end of the spoke 1, the first connecting member 2 is used to be installed in the receiving groove 52 of the hub 5, the first connecting member 2 includes a first anti-rotation portion 22, the first anti-rotation portion 22 is used to cooperate with the receiving groove 52 of the hub 5 to limit the first connecting member 2 from rotating in the receiving groove 52 of the hub 5, thereby preventing the spokes installed between the wheel rim and the hub from rotating, improving the assembly stability, and ensuring that when the bicycle is riding, the narrow side of the spoke 1 is always facing the riding direction, reducing the riding wind resistance and ensuring riding safety.

[0029] In this embodiment, the first connecting member 2 further includes a first sleeve 21 , and the first anti-rotation portion 22 includes an annular diameter expansion portion 221 arranged at the outer end of the first sleeve 21 and extending radially outward, and an anti-rotation protrusion 222 arranged on one side of the annular diameter expansion portion 221 .

[0030] In this embodiment, the extension direction of the anti-rotation protrusion 222 is perpendicular to the axial direction of the first sleeve 21, and right-angled sections 223 are formed between the two sides of the anti-rotation protrusion 222 and the annular expanded diameter portion 221, further improving the anti-rotation limit stability.

[0031] Of course, in other cases, it is also possible to have a smooth transition between the two sides of the anti-rotation protrusion and the annular expanded diameter portion through an arc surface, thereby reducing the friction between the first connecting member and the hub and extending the service life.

[0032] In this embodiment, a flat cut surface 224 is formed on one side of the annular enlarged diameter portion 221 away from the anti-rotation protrusion 222 , thereby achieving dual anti-rotation limitation on both sides of the first connecting member 2 .

[0033] In this embodiment, a second connecting member 3 is fixedly installed at the other end of the spoke 1. The second connecting member 3 includes a second sleeve 31 with an external thread and an elliptical second anti-rotation portion 32 arranged at the inner end of the second sleeve 31. The second sleeve 31 extends into the interior of the rim 4 through the spoke hole 41 and cooperates with the nut to connect the spoke 1 to the rim 4. The second anti-rotation portion 32 is used to be limitedly inserted into the spoke hole 41 of the rim 4. The shape of the spoke hole 41 is an ellipse corresponding to the shape of the second anti-rotation portion 32, thereby preventing the second connecting member 3 from rotating in the spoke hole 41. The shape and structure of the second anti-rotation portion 32 are easy to process and have good stability. Of course, the second anti-rotation portion 32 can also be other shapes, as long as the shape of the spoke hole 41 corresponds to the shape of the second anti-rotation portion 32, the anti-rotation function of the second anti-rotation portion 32 can be achieved, such as a square.

[0034] In this embodiment, the first connecting member 2 is a cap head, the second connecting member 3 is a thread cap, and the spoke 1 is made of carbon fiber composite material, which has high strength and is lighter. The spoke 1 includes a main body 11 and end heads 12 located at both ends of the main body 11. The main body 11 is flat, so as to reduce wind resistance. The end head 12 is a conical end head with a small inside and a large outside. The thread cap and the cap head are respectively provided with conical holes corresponding to the conical end heads. The thread cap and the cap head are respectively fixedly mounted on the conical end heads at both ends of the main body 11 through the conical holes, thereby forming a complete spoke mechanism. The spoke mechanism has better assembly stability, which prevents the thread cap and the cap head from detaching from the two ends of the main body 11, thereby improving safety.

[0035] The wheel rim assembly with anti-rotation spokes of this embodiment also includes a wheel rim and a hub, and the two ends of the spokes are connected to the hub and the wheel rim respectively through a cap and a threaded cap. Specifically, a plurality of spoke holes 41 are provided on the circumferential inner wall of the wheel rim 4. The shape of the spoke holes 41 is an ellipse corresponding to the shape of the second anti-rotation portion 32. The second anti-rotation portion 32 is limitedly inserted into the spoke holes 41 of the wheel rim 4. A plurality of accommodating slots are provided on the hub 5. The accommodating slots include an introduction hole 51 located at the edge of the hub 5 and an accommodating slot 52 connected to the introduction hole 51. The cap is introduced through the introduction hole 51 and pulled back so that the first anti-rotation portion 22 is limitedly installed in the accommodating slot 52. Specifically, the accommodating slot 52 includes a first groove 521 and a second groove 522 arranged in sequence in a direction away from the introduction hole 51. The first anti-rotation portion 22 and the first shaft sleeve 21 are respectively limitedly installed in the first groove 521 and the second groove 522. The depth of the first groove 521 is greater than the depth of the second groove 522, and the size of the introduction hole 51 is greater than the size of the accommodating groove 52, so that the cap head is introduced through the introduction hole 51 and pulled back to be limited and installed in the accommodating groove 52, wherein the annular enlarged diameter portion 221 is limited and installed in the first groove 521, and the anti-rotation protrusion 222 is limited and clamped at the notch of the first groove 521, and the flat surface limit card is set at the bottom of the first groove 521, thereby realizing double anti-rotation. This arrangement enables the tooth cap and the cap head to be respectively anti-rotation and limited and assembled on the rim 4 and the hub 5, thereby preventing the wheel rim spokes from rotating, improving the assembly stability, and making the narrow side of the spoke 1 always face the riding direction when the bicycle is riding, reducing the riding wind resistance and ensuring riding safety.

[0036] In this embodiment, the second anti-rotation portion 32 is a fully hidden limiter inserted into the spoke hole 41 of the rim 4, preventing the second anti-rotation portion 32 from being exposed outside the spoke hole 41, further reducing the riding wind resistance, and under the premise of ensuring product performance and stability, the product is designed to be lighter.

[0037] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims shall fall within the scope of protection of the present invention.
