Description

Technical Field

[0001] This disclosure relates to the field of bicycle technology, specifically to a spoke and a wheel. Background Art

[0002] Bicycles often use spoked wheels, which typically include a rim, axle, tire, and multiple spokes. The axle is located inside the rim, and each spoke is located between the axle and the rim. One end of each spoke is connected to the axle, and the other end is connected to the rim. The tire is fitted onto the rim.

[0003] One drawback of spoked wheels is that the spokes are prone to breakage, especially during maintenance or malicious damage. The spokes are the weakest point of the entire wheel assembly, and a single broken spoke can affect the lifespan of the entire wheelset, leading to a high repair rate. The end of the spoke that connects to the axle is the most vulnerable point. When a spoke breaks at this point, it is usually necessary to first remove the tire, then detach the end of the spoke that connects to the rim, and finally pull the entire spoke out of the axle hole to remove it completely. The spoke removal and installation process is relatively complex, resulting in low spoke replacement efficiency and significantly impacting work time. Utility Model Content

[0004] This disclosure provides a spoke and wheel that improves spoke replacement efficiency and saves materials.

[0005] In a first aspect, embodiments of the present invention provide a spoke, comprising:

The bent head of the first body is fitted with the wheel axle for limiting. The rim connection portion of the second body of each spoke is threaded to the spoke nut.

[0029] When the spokes provided in this embodiment break at the bend end of the first spoke body, the connection between the first and second spoke bodies can be released by operating the connector. The first spoke body is short and can be easily and quickly removed and replaced with a new first spoke body.

DETAILED DESCRIPTION

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0041] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0043] Figure 1 A schematic diagram of the external structure of the spoke 100 provided in an embodiment of this disclosure is shown. Figure 4 This diagram illustrates the structure of a wheel provided in an embodiment of the present disclosure. The spoke 100 provided in this embodiment includes a first spoke 1 and a second spoke 2. The first spoke 1 can be connected to the axle 300 of the wheel 300, and the second spoke 2 can be connected to the rim 200 of the wheel. The first spoke 1 and the second spoke 2 are detachably connected. If one of the first spoke 1 and the second spoke 2 breaks, only the broken first spoke 1 or the broken second spoke 2 needs to be replaced, without replacing the unbroken one. Compared to replacing the entire spoke 100, replacing only the first spoke 1 or the second spoke 2 is a simpler process and saves materials.

[0044] Typically, the end of the first spoke 1 that connects to the axle 300 is a vulnerable part. When the first spoke 1 breaks at one end of the axle 300, the connection between the first spoke 1 and the second spoke 2 can be severed, the first spoke 1 can be removed from the axle 300 side, and a new first spoke 1 can be replaced. The second spoke 2 does not need to be removed, thus eliminating the need to remove the tire 400, which significantly improves the efficiency of spoke 100 replacement and saves materials.

[0045] Figure 2 An exploded view of a spoke provided in an embodiment of this disclosure is shown. (In conjunction with...) Figure 1 and Figure 2As shown, the spoke 100 also includes a connector 3. One end of the first spoke 1 has a bend 11. After the first spoke 1 passes through the axle hole 310 on the wheel axle 300, the end of the bend 11 is confined within the axle hole 310. The other end of the first spoke 1 has a first mating portion 12. The second spoke 2 extends in a straight line. One end of the second spoke 2 has a second mating portion 21, and the other end has a rim connecting portion 22 for connecting with the wheel rim 200. The connector 3 is located between the first spoke 1 and the second spoke 2. The connector 3 can be combined with the first mating portion 12 and the second mating portion 21 respectively to connect the first spoke 1 and the second spoke 2. The connector 3 is at least detachably connected to the first mating portion 12.

[0046] By providing an independent connector 3, the first strip 1 and the second strip 2 can be easily connected or separated. The connector 3 and the first mating part 12 can be connected by threaded connection, snap-fit, fastener connection, or other connection methods. The connector 3 and the second mating part 21 can also be connected by threaded connection, snap-fit, fastener connection, or other connection methods.

[0047] Considering that one end of the bend 11 of the first mating part 12 is prone to breakage, in this embodiment of the present disclosure, the connector 3 is at least detachably connected to the first mating part 12. When the first spoke 1 is disconnected from the wheel axle 300, the connection between the first mating part 12 of the first spoke 1 and the connector 3 can be disengaged. At this time, the first spoke 1 can be easily removed from the wheel axle 300 to facilitate the replacement of the new first spoke 1. After the new first spoke 1 is connected to the wheel axle 300, the connector 3 can be operated to reconnect the connector 3 to the first mating part 12 on the first spoke 1, thereby completing the replacement of the spoke 100. During this process, the connector 3 remains connected to the second spoke 2.

[0048] In some possible implementations, Figure 3 A cross-sectional view showing a partial structure of the spokes provided in an embodiment of this disclosure is shown, in conjunction with... Figure 1 , Figure 2 and Figure 3 As shown, the first mating part 12 has an external thread, the connector 3 and the second mating part 21 are rotatably mated, the connector 3 has a connecting groove 31, the connecting groove 31 has an internal thread, and the first mating part 12 is threadedly connected to the connecting groove 31.

[0049] like Figure 3 As shown, a first mating part 12 is provided at one end of the first strip body 1 away from the bent head 11. The first mating part 12 can be a threaded section provided at the end of the first strip body 1. The connector 3 and the second mating part 21 can be rotatably mated, which allows the connector 3 to rotate relative to the first mating part 12 so that the connector 3 can be threadedly connected to the first mating part 12.

[0050] In some possible implementations, the connector 3 is slidably connected to the second strip 2, and the connector 3 can slide along the second strip 2 to partially extend out of the second strip 2 and be threadedly connected to the first mating part 12. Under the action of external force, the connector 3 can rotate around the second strip 2 to gradually disengage from the first mating part 12 and move to the second strip 2.

[0051] The connector 3 can both rotate and slide along the extension direction of the second strip 2, facilitating the connection and disassembly of the connector 3 and the first strip 1. When it is necessary to disassemble the first strip 1, the connector 3 can be rotated, causing it to gradually detach from the first strip 1 and move to the second strip 2 until it is completely detached from the first strip 1. This actively avoids the first strip 1, allowing it to detach naturally without bending it, simplifying the operation. When replacing the first strip 1, it is first connected to the wheel axle 300. At this time, the first mating part 12 of the first strip 1 is close to the second strip 2 but has a gap with it. The connector 3 is slid, causing it to extend out of the first strip 1 and contact the first mating part 12. Rotating the connector 3 then threadedly connects the connector 3 and the first mating part 12.

[0052] In some possible implementations, such as Figure 3 As shown, the connector 3 has a connecting port 32 that connects to the connecting groove 31. A limiting step 33 is formed between the connecting groove 31 and the connecting port 32. The second strip 2 slidably passes through the connecting port 32. The second mating part 21 is located in the connecting groove 31 and can be limited and mated with the limiting step 33.

[0053] The inner diameter of the limiting step 33 is smaller than the outer diameter of the second mating part 21. The second mating part 21 can be a boss located at the end of the second strip 2. Before leaving the factory, the connecting piece 3 needs to be inserted onto the second strip 2 from the rim connecting part 22 side and moved to the second mating part 21 side. The second mating part 21 is accommodated in the connecting groove 31, and the connecting piece 3 will no longer detach from the second strip 2. The first strip 1 and the second strip 2 can be connected or disconnected simply by rotating the connecting piece 3.

[0054] In some possible implementations, the connecting groove 31 includes a threaded groove section 311 and a limiting groove section 312. The threaded groove section 311 has an internal thread, and the limiting groove section 312 communicates with the threaded groove section 311. The limiting groove section 312 has a smooth inner wall, and the communicating port 32 communicates with the limiting groove section 312. The second mating part 21 can be located within the limiting groove section 312.

[0055] The threaded groove section 311, the limiting groove section 312, and the connecting port 32 are arranged sequentially along the length of the connector 3. The threaded groove section 311 is used for threaded connection with the first mating part 12, the limiting groove section 312 is used for limiting engagement with the second mating part 21, and the connecting port 32 is used to avoid the second strip 2. The inner wall of the limiting groove section 312 does not have internal threads and has a smooth surface to avoid excessive contact between the internal threads and the second mating part 21, which would make them prone to severe wear due to rigid compression.

[0056] In some possible implementations, the extension length of the limiting groove 312 along the length direction of the connector 3 is greater than the extension length of the second mating part 21, so that when the connector 3 is connected to the first strip 1 and the second strip 2, the second mating part 21 can be completely accommodated in the limiting groove 312, and the second mating part 21 will not come into contact with the internal thread, thereby improving product quality.

[0057] In some possible implementations, such as Figure 1 As shown, the outer wall of the connector 3 is provided with a first rotation operation mating part 34. The first rotation operation mating part 34 may include several flat surfaces provided on the outer wall of the connector 3. The flat surfaces are provided so that the connector 3 can be easily rotated after being clamped with a professional tool, and the connector 3 can be prevented from slipping on the professional tool. For example, the professional tool can be a wrench, and the cross-section of the first rotation operation mating part 34 can be polygonal. The two clamping arms of the wrench can clamp the connector 3, so that the two clamping arms respectively fit against the two opposite flat surfaces of the first rotation operation mating part 34. Rotating the wrench can drive the connector 3 to rotate synchronously.

[0058] In some possible implementations, a second rotational operating engagement portion 23 is provided on the outer wall of the second strip 2. The second rotational operating engagement portion 23 may include several flat surfaces provided on the outer wall of the second strip 2. The flat surfaces facilitate easy rotation of the second strip 2 after it has been clamped with a specialized tool, preventing slippage on the tool. For example, the specialized tool can be a wrench. The second rotational operating engagement portion 23 may include flat surfaces on opposite sides of the second strip 2. The two clamping arms of the wrench can clamp the connecting piece 3, so that the two clamping arms respectively conform to the two opposite flat surfaces. Rotating the wrench applies torque to the second strip 2, causing the second strip 2 to rotate synchronously with the wrench, thereby facilitating the connection or separation between the second strip 2 and the rim 200.

[0059] Figure 4 This diagram illustrates the structure of a wheel provided in an embodiment of the present disclosure. Figure 5 Show Figure 4 Enlarged view of section A. Combined with... Figure 1 , Figure 4 and Figure 5As shown, the rim connection 22 may include a stud, and the spoke nut may be provided on the rim 200 of the wheel. When the second spoke 2 is broken or damaged, it needs to be replaced. At this time, the rim connection 22 of the new second spoke 2 can be aligned with the threaded hole of the spoke nut, and then the second spoke 2 can be rotated to screw the end of the second spoke 2 into the spoke nut. During this process, the operator can use the above-mentioned professional tools to rotate the second spoke 2 to tightly thread the second spoke 2 onto the spoke nut.

[0060] In some possible implementations, the connector 3 can be a metal cylinder, which can be respectively fitted onto the first strip 1 and the second strip 2. The metal cylinder covers the disconnected area between the first strip 1 and the second strip 2. The metal cylinder can both connect the first strip 1 and the second strip 2 and cover the disconnected area between the first strip 1 and the second strip 2, protecting the first mating part 12 and the second mating part 21, and also serving a concealing and aesthetic purpose. The connector 3 can be made of iron or copper.

[0061] Combination Figure 4 and Figure 5 As shown in the illustration, this application also provides a wheel, including: a rim 200, an axle 300, and a plurality of spokes 100 as described above. A spoke nut is provided on the rim 200. The axle 300 is located inside the rim 200 and has a plurality of axle holes 310. Each spoke 100 is arranged sequentially along the circumference of the axle 300. The first body 1 of the spoke 100 passes through the corresponding axle hole 310. The bent head 11 of the first body 1 is fitted with the axle 300 for limiting. The rim connecting portion 22 of the second body 2 of the spoke 100 is threadedly connected to the spoke nut. The wheel of this application uses the aforementioned spokes 100, thus also possessing the advantages of convenient spoke replacement, high efficiency in spoke assembly and disassembly, and material saving.

[0062] The above description has been given for purposes of illustration and description. Furthermore, this description is not intended to limit the embodiments of this disclosure to the forms disclosed herein.
