Description

Technical Field

[0001] This utility model relates to the field of bicycle wheel assembly technology, specifically to a spoke rim connection structure, a spoke rim assembly tool, a wheel assembly, and a bicycle. Background Technology

[0002] A bicycle wheelset mainly consists of hubs, rims, spokes, and tires. The hub, located at the center of the wheelset, contains bearings and connects the rim and spokes to ensure smooth wheel rotation. The rim is the outer frame of the wheelset, used to mount the tire and connected to the hub via spokes. Spokes are slender, rod-like components connecting the hub and rim; multiple spokes are arranged circumferentially or in a straight line within the wheelset to provide support and transmit force. The tire is mounted on the outside of the rim, directly contacting the ground and providing grip, cushioning, and protection for the bicycle.

[0003] Current spoked rim connection structures typically involve evenly distributed holes along the circumference of the rim, with threads at the ends of the spokes. After inserting the spoke ends into the holes on the rim, spoke nuts are screwed on. The spoke nuts press against the rim, tightening the spokes and ensuring a secure connection. The spoke tension can be adjusted by changing the tightness of the spoke nuts. Appropriate spoke tension is crucial for the stability and strength of the wheel. Insufficient spoke tension may cause the wheel to deform or "bounce" during riding; excessive spoke tension may put excessive stress on the rim and hub, leading to component damage.

[0004] The aforementioned spoked rim connection structure requires through mounting holes on the rim. Current rims come in two types: those with external holes and those without. Rims with external holes have a through hole on the wall where the tire is mounted, allowing a wrench to be inserted. Additionally, there's a corresponding through hole on the inner edge of the brake rim for the spokes to pass through, allowing for easy tightening of the nuts during installation. Rims without external holes lack this through hole; tightening the nuts requires accessing the inside of the rim, inserting them from the valve stem. Rims with external holes, due to the increased number of through holes, suffer from reduced structural strength. Rims without external holes allow for spoke tension adjustments without removing the tire, directly from the inside of the rim. However, when installing spokes on wheel rims without external holes, the nuts can only be inserted from the valve stem position, and then the nuts must be moved from inside the wheel rim to the corresponding spoke hole position, making installation relatively inconvenient.

[0005] To address this, existing technologies have proposed a structure where the nut is fixed to the rim. When connecting the spokes, another nut is screwed onto the nut, and the spokes then engage with this nut in an axial upper limit to achieve a fixed connection between the spokes and the rim. However, in this structure, the spokes and rim can only be indirectly engaged via the nut, leading to unstable spoke tension adjustment. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned defects or problems in the background art and provide a spoke wheel rim connection structure, a spoke wheel rim assembly tool, a wheel set, and a bicycle.

[0016] Technical solution nine based on technical solution eight: the first mating part and the second mating part are at least one set of grooves arranged symmetrically along the circumference of the nut and the spoke, and the opening of the groove faces the inner side of the wheel rim radially.

[0017] Technical solution ten based on technical solution one: the second anti-rotation part is hole-shaped, and the first anti-rotation part is inserted into the second anti-rotation part and is limited by the second anti-rotation part in the circumferential direction to form an anti-rotation fit.

[0018] Technical solution eleven based on technical solution ten: The second anti-rotation part is a through hole.

[0019] In addition, this utility model also provides technical solution twelve: a spoke wheel rim assembly tool, which is used to assemble spokes in the spoke wheel rim connection structure as described in any one of technical solutions one to eleven to the wheel rim, characterized in that it includes a rotary wrench and an anti-rotation wrench; the rotary wrench is provided with a first mating part for axially mating with the nut and circumferentially anti-rotation; the anti-rotation wrench is provided with a second mating part for axially mating with the spoke and circumferentially anti-rotation.

[0022] In addition, this utility model also provides technical solution fifteen: a bicycle, which includes a frame, characterized in that the frame is equipped with a wheel set as described in technical solution fourteen.

[0023] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0024] Technical solution one provides a spoke rim connection structure, which is used to connect spokes to the rim, and can facilitate the adjustment of spoke tension and ensure the stability of spoke tension adjustment.

[0025] In this spoked rim connection structure, the spokes have a threaded portion and a first anti-rotation portion. A receiving cavity is provided in the rim, and an axially sliding nut is installed within the receiving cavity. The end of the spoke can be inserted into the receiving cavity through a mounting hole, forming a threaded connection with the nut in the receiving cavity. During the tightening of the nut, the spoke needs to be fixed circumferentially, and then the nut is rotated so that it approaches the first limiting wall of the receiving cavity axially until the nut and the first limiting wall are tightly abutted, at which point the spoke is tightened and fixed to the rim. A second anti-rotation portion is provided on the second limiting wall of the receiving cavity. The first and second anti-rotation portions can form a circumferential anti-rotation fit, effectively restricting the rotation of the spoke around its own axis after it is assembled to the rim. This improves the torsional deformation of the spoke under stress, reduces the torsional stress of the spoke, and thus improves the tension transmission efficiency. This effectively increases the lacing tension, reduces spoke fatigue damage, extends spoke service life, and improves the durability of the wheelset. Furthermore, by adjusting the tightness of the nut, precise adjustment of the spoke tension can be easily achieved. Since the nut is directly connected to the threaded portion of the spoke, adjustments to the nut are directly transmitted to the spoke through the threaded connection, significantly improving the efficiency and stability of tension transmission compared to methods using limiting fits. Moreover, because the first anti-rotation part of the spoke and the second anti-rotation part of the rim form an anti-rotation fit, the spoke is already fixed circumferentially. Therefore, when adjusting the spoke tension by turning the nut, the set spoke tension value can be well maintained, preventing changes in tension due to vibration or loosening during use.

[0026] However, because a second anti-rotation part is provided on the second limiting wall of the accommodating cavity, the first anti-rotation part of the spoke needs to accurately form an anti-rotation fit with the second anti-rotation part during assembly. However, when the spokes are assembled to the rim, they are usually not straightened, and after being inserted into the mounting hole, the spokes will still have a certain degree of bending. Obviously, a bent spoke cannot achieve an accurate fit between the first and second anti-rotation parts. Therefore, in this technical solution, the nut is designed to slide axially, while the sliding range of the nut is limited by the cooperation of the first and second limiting walls. In the initial assembly stage, the threaded portion at the spoke end is just inserted into the mounting hole and forms a preliminary threaded connection with the nut. At this time, the spoke pushes the nut, typically pushing it to the position against the second limiting wall. Then, as the nut is rotated, the spoke gradually straightens, increasing the threaded engagement between the spoke and the nut. The first anti-rotation part at the spoke end is gradually guided to align with the second anti-rotation part until the first anti-rotation part protrudes from the nut. At this point, the spoke is straightened. Continuing to rotate the nut allows the first and second anti-rotation parts to accurately engage, forming an anti-rotation connection. This two-stage assembly method ensures the orderly and reliable spoke assembly process. In stage one, the axial sliding of the nut smoothly forms a threaded connection with the nut and straightens the spoke. In stage two, the spoke is straightened and aligned with the second anti-rotation part. Then, rotating the nut tightens the spoke, ensuring the orderly and reliable assembly process and effectively guaranteeing the accurate engagement between the first and second anti-rotation parts. This further improves the torsional stress on the spoke, thereby increasing the spool tension.

[0027] In technical solution two, a plug-in portion is provided on the nut, which has a clearance fit with the mounting hole, allowing the nut to slide axially while facilitating its rotation from the plug-in position. Furthermore, with the nut internally within the receiving cavity and still sliding axially, the plug-in portion easily guides the threaded portion of the spokes into the nut in the correct direction, initially forming a threaded connection with the nut's internal threads. Without the plug-in portion, when the nut slides away from the mounting hole, it becomes difficult to locate the nut's internal threads after the spokes pass through the mounting hole, leading to reduced assembly efficiency.

[0028] In technical solution three, since the insertion part is located in the mounting hole, it is easily obscured by the mounting hole. After the spoke is inserted into the mounting hole, it is easy to misalign the hole of the insertion part. Therefore, a guide slope can be set to guide the end of the spoke into the insertion part, thereby improving assembly efficiency.

[0029] In technical solution four, the nut body slides axially in the sliding cavity of the receiving cavity, and the outer diameter of the nut body is smaller than the inner diameter of the sliding cavity. The axial sliding of the nut is limited by the clearance fit between the insertion part and the mounting hole. The sliding cavity plays a role in preventing the nut body from deflecting. When the nut is rotated, the nut body does not need to contact the cavity wall of the sliding cavity, thereby reducing the resistance when rotating the nut and further reducing the torsional stress on the spokes.

[0030] In technical solution five, the abutment fit between the first limiting wall and the first abutment wall of the nut body is designed as a conical fit structure. This structure allows the nut to maintain its position in a more centered state when it abuts against the first limiting wall, preventing the nut's position from shifting relative to the axial direction of the mounting hole. At the same time, compared with the planar contact structure, it can further increase the contact area, disperse stress, thereby improving the reliability and durability of the connection. Furthermore, because the stress is dispersed, the wheel tension can be further increased, improving the rigidity of the wheel set.

[0031] In technical solution six, the wheel rim includes a wheel rim body, a first embedded part, and a second embedded part. The split design facilitates the forming of the receiving cavity, reduces the difficulty of processing and manufacturing, and allows the nut to be easily placed into the receiving cavity. In addition, it facilitates the selection of different materials. For example, the first and second embedded parts can be made of materials more suitable for processing complex shapes or having specific functions, while the wheel rim body can be made of materials that emphasize lightweighting or strength, thus achieving optimized material configuration.

[0032] In technical solution seven, a first mating part is provided on the nut to cooperate with the assembly tool, allowing the nut to be turned using a specialized assembly tool, thus improving assembly efficiency and ease of operation. Simultaneously, in conjunction with the assembly tool, precise control of the nut tightening torque can be achieved, thereby more accurately controlling the spoke tension.

[0033] In technical solution eight, the second mating part on the spokes allows the spokes to be fixed using specialized assembly tools, preventing the spokes from rotating when the nut is turned, ensuring the effectiveness of the anti-rotation fit, and simplifying the assembly operation.

[0034] In technical solution nine, the first and second mating parts are designed as circumferentially symmetrical grooves. The groove structure is simple to process, has low cost, and has good versatility in matching with assembly tools. The circumferentially symmetrical arrangement of the grooves makes the force and torque applied by the assembly tool more uniform and balanced, avoiding deformation or damage to the parts caused by unilateral force.

[0035] In technical solution ten, the first anti-rotation part and the second anti-rotation part are designed as a hole-shaft anti-rotation structure, which has a reliable anti-rotation effect. At the same time, the hole-shaped second anti-rotation part is easier to guide the first anti-rotation part to be aligned and inserted compared to other shapes, thus improving the assembly success rate.

[0036] In technical solution eleven, the second anti-rotation part is designed as a through hole. The structure of the through hole allows the first anti-rotation part to extend out from the second anti-rotation part. Compared with the countersunk hole structure, the spoke length design can have more redundant space, and at the same time, it can also have a larger adjustment space when adjusting the spoke tension.

[0037] Technical solution twelve provides a spoked wheel rim assembly tool, which includes a rotary wrench and an anti-rotation wrench. This assembly tool can be used in conjunction with the spoked wheel rim connection structure in the above technical solution to fully leverage its advantages of simplified assembly and precise tension adjustment.

[0038] In technical solution thirteen, the rotary wrench and the anti-rotation wrench are designed as a nested sleeve structure. This sleeve structure allows the rotary wrench and the anti-rotation wrench to be integrated into one compact structure, making operation convenient. Simultaneously, the sleeve structure allows the operator to control both the rotary wrench and the anti-rotation wrench at the same time, achieving synchronous rotation of the nut and fixing of the spokes, thus improving assembly efficiency.

[0039] Technical solution fourteen provides a wheelset including a rim, hub and spokes, which adopts the spoke rim connection structure provided by technical solutions one to eleven above. Due to the improvement of the connection structure, the overall performance of the wheelset is improved, and it has the effects of simplified assembly, improved spoke torsional strength and improved wheel tension.

[0040] Technical solution 15 provides a bicycle that uses the aforementioned wheelset. Due to the improved performance of the wheelset, the overall performance of the bicycle and the user experience are both enhanced. Attached Figure Description

[0068] Example

[0069] This utility model relates to a bicycle, which includes a frame and wheelsets. The frame employs a conventional structure in the art, and its material can be metal or carbon fiber. The wheelsets are one aspect of the bicycle described in this utility model embodiment, and will be detailed below. The wheelsets are conventionally mounted on the frame and, together with conventional drivetrain, braking system, and other components, constitute a complete bicycle.

[0070] Reference Figure 1 This illustration shows the structure of a wheelset according to an embodiment of the present invention. The wheelset includes a rim 20, a hub 50, and a plurality of spokes 10. The spokes 10 are connected to the rim 20 using a spoke-rim connection structure, which is one aspect of the bicycle according to an embodiment of the present invention. Simultaneously, the spokes 10 are connected to the hub 50, and the hub 50 is connected to the frame, thereby assembling the wheelset to the frame. The aforementioned spoke-rim connection structure and the structure connecting the spokes 10 to the hub 50 will be described in detail below.

[0071] It is necessary to note that, due to the numerous rotating structures and rotational movements, this specification and claims extensively use axial, radial, and circumferential directions to define position and movement. These axial, radial, and circumferential directions may not be the same for different components; the directions shown in the drawings and described in the specification shall prevail. For example, in... Figure 1In the design, the rim 20 is circular, the hub 50 is located at its center, its axial direction is the extension direction of the hub 50, its radial direction is the direction in which the rim 20 extends to the hub 50, and its circumferential direction is the circular direction of the rim 20 itself.

[0072] The following section will first explain the spoke wheel rim connection structure described above.

[0073] Reference Figure 2 , Figure 3 and Figure 6 The spoke 10 has a threaded portion 11 on its end sidewall and a first anti-rotation portion 12 at its end. The rim 20 has accommodating cavities 21 evenly arranged circumferentially, and a nut 22 adapted to be threadedly engaged with the threaded portion 11 is installed in the accommodating cavity 21. The accommodating cavity 21 has an opening radially toward the inner side of the rim 20 to form a mounting hole 213 for inserting the spoke 10. The nut 22 is slidably engaged in the accommodating cavity 21 along its axial direction and is adapted to abut against a first limiting wall 211 and a second limiting wall 212 provided in the accommodating cavity 21 and opposite to it in its axial direction to limit the sliding range. The first limiting wall 211 is close to the mounting hole 213, and the second limiting wall 212 is away from the mounting hole 213 and is provided with a second anti-rotation portion 215 facing the nut 22; the first anti-rotation portion 12 is adapted to engage with the second anti-rotation portion 215 to restrict the spoke 10 from rotating about its axial direction, and after the threaded portion 11 is screwed to the nut 22 and before the first anti-rotation portion 12 and the second anti-rotation portion 215 form an anti-rotation engagement, the axial position of the nut 22 in the receiving cavity 21 is configured to straighten the spoke 10 so that the first anti-rotation portion 12 is aligned with the second anti-rotation portion 215.

[0074] Specifically, first refer to Figure 6The diagram illustrates the structure of the spoke 10 as described in this embodiment. It should be understood that the structure of the spoke 10 ends varies depending on the material. For example, in this embodiment, the spoke 10 includes a strip-shaped spoke body 15 and metal parts fixedly disposed at both ends of the spoke body 15. The spoke body 15 is made of carbon fiber, and external threads are provided on the metal parts fixedly disposed at both ends. The external thread at the end for connection with the rim 20 forms a threaded portion 11. In other embodiments, the spoke 10 can be made of metal, in which case external threads can be directly provided at both ends of the spoke 10 without the need for additional metal parts. In this embodiment, a metal part is provided at the first end of the spoke body 15 along the axial direction. This metal part is fixedly connected to the spoke body 15 as a single unit. The connection method allows the spoke body 15 and the metal part to form a fixed fit in both the axial and circumferential directions. That is, the metal part will not detach from the spoke body 15 along the axial direction, nor will it rotate relative to the spoke body 15 in the circumferential direction. Meanwhile, a first anti-rotation part 12 is provided at the end of the first end of the spoke 10. The first anti-rotation part 12 can be provided on the metal part or on the spoke body 15. If it is provided on the spoke body 15, the spoke body 15 needs to extend out of the metal part along the axial direction.

[0075] Among them, reference Figure 2 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the second anti-rotation part 215 is hole-shaped, and the first anti-rotation part 12 is inserted into the second anti-rotation part 215 and limited in the circumferential direction by the second anti-rotation part 215 to form an anti-rotation fit. For example, the second anti-rotation part 215 can be configured as a countersunk hole structure, and the hole of the second anti-rotation part 215 can be formed as a non-circular shape or a shape with edges, such as elliptical or rectangular. In this embodiment, the second anti-rotation part 215 is designed as a square. At the same time, the first anti-rotation part 12, adapted to the second anti-rotation part 215, is configured as a protruding structure, which can be inserted into the second anti-rotation part 215, and its shape is adapted to the shape of the second anti-rotation part 215, so that after the first anti-rotation part 12 is inserted into the second anti-rotation part 215, the spoke 10 cannot rotate around its axis. The first anti-rotation part 12 and the second anti-rotation part 215 are designed as a hole-shaft anti-rotation structure, which has a reliable anti-rotation effect. At the same time, the hole-shaped second anti-rotation part 215 is easier to guide the first anti-rotation part 12 to be aligned and inserted compared to other shapes, thus improving the assembly success rate.

[0076] Furthermore, the second anti-rotation part 215 is a through hole. By designing the second anti-rotation part 215 as a through hole, the structure of the through hole allows the first anti-rotation part 12 to extend out from the second anti-rotation part 215. Compared with the structure of a countersunk hole, the length design of the spoke 10 can have more redundant space, and at the same time, it can also have a larger adjustment space when adjusting the tension of the spoke 10.

[0077] Reference Figure 2 and Figure 3 The wheel rim 20 includes a wheel rim body 23, a first embedded part 24, and a second embedded part 25; the first embedded part 24 and the second embedded part 25 are fixedly connected to each other and are both fixedly disposed on the wheel rim body 23, and cooperate to form the receiving cavity 21; the first limiting wall 211 and the mounting hole 213 are disposed on the first embedded part 24; the second limiting wall 212 and the second anti-rotation part 215 are disposed on the second embedded part 25; the wheel rim body 23 is provided with a through hole 231 corresponding to the mounting hole 213.

[0078] Among them, reference Figure 1 The wheel rim body 23 is annular and can be made of carbon fiber or metal. In the brake edge structure of the wheel rim body 23, a plurality of through holes 231 are evenly distributed along the circumference of the wheel rim body 23. Corresponding to the positions of these through holes 231, a receiving cavity 21 formed by the cooperation of a first embedded part 24 and a second embedded part 25 is provided. (Refer to...) Figure 4 and Figure 5 The first embedded part 24 is located axially below the second embedded part 25. The first embedded part 24 is hollow inside, with its axial top end open and external threads provided on the outer peripheral surface of its axial top end. The second embedded part 25 has internal threads that match the external threads of the first embedded part 24 and can be screwed to the top end of the first embedded part 24 to close the top opening of the first embedded part 24. The bottom end of the first embedded part 24 is also open in the axial direction and forms a mounting hole 213. The mounting hole 213 extends axially, and the portion of the accommodating cavity 21 other than the mounting hole 213 forms a sliding cavity 214. Therefore, the first embedded part 24 can be divided into a protruding structure with mounting hole 213 and a main body forming the main part of the first embedded part 24. The outer diameter of the portion of the first embedded part 24 with mounting hole 213 is smaller than the outer diameter of the main body of the first embedded part 24. Figure 2 and Figure 3The mounting hole 213 of the first embedded part 24 corresponds precisely to the through hole 231 on the wheel rim body 23. Simultaneously, the outer surface of the main body of the first embedded part 24 is a polygonal shape with sharp edges, which improves the circumferential fixing effect between the first embedded part 24 and the wheel rim body 23 when the first embedded part 24 is fixed to the wheel rim body 23. The second embedded part 25 has the aforementioned second anti-rotation part 215 located in the middle of the bottom wall of the second limiting wall 212. In this embodiment, the second anti-rotation part 215 is a square through hole. In this embodiment, the split design of the wheel rim 20 facilitates the forming of the receiving cavity 21, reduces the manufacturing difficulty, and allows for easy placement of the nut 22 into the receiving cavity 21. Furthermore, it facilitates the selection of different materials; for example, the first embedded part 24 and the second embedded part 25 can be made of materials more suitable for processing complex shapes or having specific functions, while the wheel rim body 23 can be made of materials that prioritize lightweight or strength, achieving optimized material configuration.

[0079] Reference Figure 2 , Figure 4 and Figure 5 A nut 22 is installed in the accommodating cavity 21. The center of the nut 22 forms a through hole with internal threads, allowing it to thread into the threaded portion 11 at the end of the spoke 10. The nut 22 has an insertion portion 221 that communicates axially with its internal thread. The insertion portion 221 is inserted into the mounting hole 213 and maintains a clearance fit with the mounting hole 213 throughout the sliding range of the nut 22. The spoke 10 is adapted to pass through the insertion portion 221 axially to thread into the nut 22. Furthermore, a guide slope 222 is provided along the inner edge of the free end of the insertion portion 221, and the inner diameter of the guide slope 222 gradually increases from the inside to the outside along the axial direction of the nut 22. The portion of the nut 22 located in the sliding cavity 214 is the nut body 223, and the outer diameter of the nut body 223 is smaller than the inner diameter of the sliding cavity 214.

[0080] Reference Figure 2 The first limiting wall 211 is provided in the sliding cavity 214, and the inner diameter of the first limiting wall 211 gradually decreases from the inside to the outside along the axial direction of the nut 22; the nut body 223 is provided with a first abutting wall 224 for abutting and cooperating with the first limiting wall 211, and the outer diameter of the first abutting wall 224 gradually increases from the inside to the outside along the axial direction of the nut 22 and is adapted to the shape and size of the first limiting wall 211.

[0081] Specifically, refer to Figure 2 , Figure 3 , Figure 4 and Figure 5The accommodating cavity 21 contains a first limiting wall 211 and a second limiting wall 212 that are axially opposed. The second limiting wall 212 is the bottom wall of the second embedded part 25, and is a planar structure perpendicular to the axis of the nut 22. The first limiting wall 211 is disposed in the sliding cavity 214 portion of the accommodating cavity 21, and the second limiting wall 212 is an inclined conical structure. The nut 22 has a second abutment wall 225 facing the second limiting wall 212 and a first abutment wall 224 that matches the shape of the first limiting wall 211. (Refer to...) Figure 4 The nut 22 has an axially extending insertion portion 221 on its lower axial side. The insertion portion 221 can extend into the mounting hole 213 of the second embedded part 25, allowing the nut 22 to slide back and forth axially. A guide slope 222 is also provided along the inner edge of the free end of the insertion portion 221. The inner diameter of the guide slope 222 gradually increases from the inside to the outside along the axial direction of the nut 22. This structure has the portion containing the accommodating cavity 21 as the inside and the portion outside the accommodating cavity 21 as the outside, gradually increasing in the axial direction. In other words, the free end of the insertion portion 221 gradually opens from the inside to the outside, making it easier for the end of the spoke 10 to be inserted into the nut 22.

[0082] In this embodiment, a plug-in portion 221 is provided on the nut 22. The plug-in portion 221 is clearance-fitted with the mounting hole 213, thereby allowing the nut 22 to slide axially and facilitating its rotation from the position of the plug-in portion 221. Furthermore, when the nut 22 is inside the receiving cavity 21 and is still sliding axially, the plug-in portion 221 facilitates guiding the threaded portion 11 of the spoke 10 into the nut 22 in the correct direction and initially forming a threaded connection with the internal thread of the nut 22. Without the plug-in portion 221, when the nut 22 slides away from the mounting hole 213, it is difficult to locate the internal thread of the nut 22 after the spoke 10 passes through the mounting hole 213, leading to a decrease in assembly efficiency. Since the insertion part 221 is located in the mounting hole 213, it is easily obscured by the mounting hole 213. After the spoke 10 is inserted into the mounting hole 213, it is easy to misalign the hole of the insertion part 221. Therefore, a guide slope 222 can be provided to guide the end of the spoke 10 into the insertion part 221, thereby improving assembly efficiency. In addition, the nut body 223 of the nut 22 slides axially in the sliding cavity 214 of the receiving cavity 21, and the outer diameter of the nut body 223 is smaller than the inner diameter of the sliding cavity 214. The axial sliding of the nut 22 is limited by the clearance fit between the insertion part 221 and the mounting hole 213. The sliding cavity 214 serves to prevent the nut body 223 from deflecting. When the nut 22 is rotated, the nut body 223 does not need to contact the cavity wall of the sliding cavity 214, thereby reducing the resistance when rotating the nut 22 and further reducing the torsional stress on the spoke 10. Meanwhile, the abutment fit between the first limiting wall 211 and the first abutting wall 224 of the nut body 223 is designed as a conical fit structure. This structure allows the nut 22 to maintain its position in a more centered state when it abuts against the first limiting wall 211, preventing the position of the nut 22 from shifting relative to the axial direction of the mounting hole 213. Compared with the planar contact structure, it can further increase the contact area, disperse stress, thereby improving the reliability and durability of the connection. Furthermore, since the stress is dispersed, the wheel tension can be further increased, improving the rigidity of the wheel set.

[0083] Reference Figure 2 , Figure 4 and Figure 5The nut 22 has a first mating portion 226 at its free end of the insertion portion 221 for engaging with an assembly tool along the axial direction of the nut 22 to rotate the nut 22. The spoke 10 has a second mating portion 13 for engaging with the assembly tool along its axial direction to fix the spoke 10. In this embodiment, the first mating portion 226 and the second mating portion 13 are at least one set of grooves symmetrically arranged circumferentially along the nut 22 and the spoke 10, and the openings of the grooves are radially toward the inner side of the rim 20. The second mating portion 13 may be provided on the metal part of the spoke 10. The first mating portion 226 on the nut 22 for engaging with the assembly tool allows the nut 22 to be rotated using a specialized assembly tool, improving assembly efficiency and ease of operation. At the same time, with the assembly tool, precise control of the tightening torque of the nut 22 can be achieved, thereby more accurately controlling the tension of the spoke 10. The second mating part 13 on the spoke 10 allows for the use of specialized assembly tools to secure the spoke 10, preventing it from rotating when the nut 22 is turned, ensuring the effectiveness of the anti-rotation fit, and simplifying the assembly operation. The first mating part 226 and the second mating part 13 are designed as circumferentially symmetrical grooves. The groove structure is simple to manufacture, has low cost, and offers good versatility in use with assembly tools. The circumferentially symmetrical arrangement of the grooves ensures that the force and torque applied by the assembly tool are more evenly balanced, avoiding deformation or damage to the parts caused by unilateral force.

[0084] Reference Figure 6 , Figure 7 and Figure 8 The spoke 10 has a connecting portion 14 at the other end opposite to the threaded portion 11. The connecting portion 14 is screwed to the hub 50 or snapped into place along its axial direction. In this embodiment, the spoke 10 and the hub 50 are connected by a threaded connection. Specifically, the hub 50 has a threaded hole 51 for screwing into the connecting portion 14 of the spoke 10, and the connecting portion 14 of the spoke 10 also has an external thread. When assembling the spoke 10, the connecting portion 14 of the spoke 10 can be screwed into the threaded hole 51 of the hub 50 first. Since the threaded hole 51 on the hub 50 is a through hole, the connecting portion 14 of the spoke 10 can continuously rotate to the appropriate position without being restricted. Therefore, when the spoke 10 and the hub 50 are firmly connected, the spoke 10 can still rotate relative to the hub 50 around its axis. Next, the threaded portion 11 of the spoke 10 is passed through the through hole 231 of the rim body 23 and inserted into the insertion portion 221 of the nut 22. At this time, the spoke 10 will have a certain degree of bending deformation, but it can still be aligned with the through hole with internal threads of the nut 22. Then, using an assembly tool, the spoke 10 is fixed in the circumferential direction, and the nut 22 is rotated in the circumferential direction to tighten the spoke 10 and fix it to the rim 20.

[0085] As one aspect of this utility model embodiment, the above-mentioned spoke rim connection structure is used to connect the spokes 10 to the rim 20, which facilitates the adjustment of the tension of the spokes 10 and ensures the stability of the tension adjustment. In this spoke rim connection structure, the spokes 10 are provided with a threaded portion 11 and a first anti-rotation portion 12. A receiving cavity 21 is provided in the rim 20, and an axially sliding nut 22 is installed in the receiving cavity 21. The end of the spokes 10 can be inserted into the receiving cavity 21 through the mounting hole 213 and form a threaded connection with the nut 22 in the receiving cavity 21. During the process of tightening the nut 22, the spokes 10 need to be fixed in the circumferential direction, and then the nut 22 is rotated so that the nut 22 can approach the first limiting wall 211 of the receiving cavity 21 in the axial direction until the nut 22 is tightly abutted against the first limiting wall 211, and the spokes 10 are tightened and fixed on the rim 20. The second limiting wall 212 of the accommodating cavity 21 is provided with a second anti-rotation part 215. The first anti-rotation part 12 and the second anti-rotation part 215 can form a circumferential anti-rotation fit, thereby effectively restricting the rotation of the spoke 10 around its own axis after it is assembled to the rim 20. This improves the torsional deformation of the spoke 10 under stress, reduces the torsional stress of the spoke 10, and thus improves the tension transmission efficiency. This can effectively increase the treading tension, reduce fatigue damage to the spoke 10, extend the service life of the spoke 10, and improve the durability of the wheelset. In addition, by adjusting the tightness of the nut 22, the tension of the spoke 10 can be easily and precisely adjusted. Since the nut 22 is directly connected to the threaded part 11 of the spoke 10, the adjustment of the nut 22 can be directly transmitted to the spoke 10 through the threaded connection structure. Compared with the limiting fit method, this can greatly improve the efficiency and stability of tension transmission. Furthermore, since the first anti-rotation part 12 of the spoke 10 and the second anti-rotation part 215 of the rim 20 form an anti-rotation fit, the spoke 10 is already fixed in the circumferential direction. Therefore, when adjusting the tension of the spoke 10 by rotating the nut 22, the set tension value of the spoke 10 can be well maintained, preventing the tension from changing due to vibration or loosening during use. However, since the second anti-rotation part 215 is provided on the second limiting wall 212 of the accommodating cavity 21, the first anti-rotation part 12 of the spoke 10 needs to accurately form an anti-rotation fit with the second anti-rotation part 215 during the assembly process. However, when the spoke 10 is assembled to the rim 20, it is usually not straightened. After being inserted into the mounting hole 213, the spoke 10 will still have a certain degree of bending. The bent spoke 10 obviously cannot achieve an accurate fit between the first anti-rotation part 12 and the second anti-rotation part 215. Therefore, in this technical solution, the nut 22 is configured to slide axially, while the sliding range of the nut 22 is limited by the cooperation of the first limiting wall 211 and the second limiting wall 212.During the initial assembly stage, the threaded portion 11 at the end of the spoke 10 is just inserted into the mounting hole 213 and forms a preliminary threaded connection with the nut 22. At this time, the spoke 10 will push the nut 22. Under normal circumstances, it will push the nut 22 to the position of abutting the second limiting wall 212. Then, as the nut 22 is rotated, the spoke 10 will gradually straighten. The threaded portion 11 and the nut 22 will have more threaded engagement parts. The first anti-rotation portion 12 provided at the end of the spoke 10 will be gradually guided to the position of aligning with the second anti-rotation portion 215 until the first anti-rotation portion 12 is exposed from the nut 22. At this time, the spoke 10 has straightened. Continue to rotate the nut 22, and the first anti-rotation portion 12 can accurately engage with the second anti-rotation portion 215 to form an anti-rotation connection. This two-stage assembly method ensures the orderly and reliable assembly process of the spokes 10. In the first stage, the spokes 10 are smoothly connected to the nut 22 by the axial sliding of the nut 22 and straightened. In the second stage, the spokes 10 are straightened and aligned with the second anti-rotation part 215. Then, the spokes 10 are tightened by rotating the nut 22. This ensures the accurate fit between the first anti-rotation part 12 and the second anti-rotation part 215, and further improves the torsional stress on the spokes 10, thereby increasing the tension of the spool.

[0086] In addition, refer to Figures 9 to 11 This utility model embodiment also relates to a spoked wheel rim assembly tool, used to assemble the spokes 10 in the above-mentioned spoked wheel rim connection structure to the wheel rim 20, which includes a rotary wrench 30 and an anti-rotation wrench 40. The rotary wrench 30 has a hollow first extension rod 32, with a first mating portion 31 located at the end of the first extension rod 32; the anti-rotation wrench 40 has a second extension rod 42, adapted to be placed within the first extension rod 32, with the second mating portion 41 located at the end of the second extension rod 42.

[0087] Specifically, both the rotary wrench 30 and the anti-rotation wrench 40 are provided with wide operating sections arranged symmetrically in the circumferential direction, allowing the operator to easily apply force to the rotary wrench 30 and the anti-rotation wrench 40 in the circumferential direction. A first extension rod 32 extending axially is provided in the middle of the operating section of the rotary wrench 30. This first extension rod 32 is hollow and slotted, with its opening facing to one side, thus forming a receiving groove 33. A first mating portion 31, adapted to the first mating portion 226 of the nut 22, is provided at the free end of the first extension rod 32. Since the first mating portion 226 is a groove structure, the first mating portion 31 is correspondingly a protruding structure. A second extension rod 42 extending axially is provided in the middle of the operating section of the anti-rotation wrench 40. This second extension rod 42 is also hollow and slotted, with its opening facing to one side. A second mating portion 41, adapted to the second mating portion 13 of the spoke 10, is provided at the free end of the second extension rod 42. Since the second mating portion 13 has a groove structure, the second mating portion 41 has a corresponding protruding structure. The groove width of the receiving groove 33 of the first extension rod 32 is approximately matched with the width of the second extension rod 42, so that the second extension rod 42 can be placed into the receiving groove 33 of the first extension rod 32. At the same time, the groove structure of the second extension rod 42 allows the spoke 10 to be placed in the second extension rod 42, so that the rotating wrench 30 and the anti-rotation wrench 40 can make way for the spoke 10 during assembly.

[0088] The aforementioned spoke wheel assembly tool can be used in conjunction with the spoke wheel connection structure in the above technical solution, fully leveraging its advantages of simplified assembly and precise tension adjustment. Specifically, the rotary wrench 30 and the anti-rotation wrench 40 are designed as nested sleeve structures, allowing for integrated use. This sleeve structure makes the rotary wrench 30 and the anti-rotation wrench 40 compact and easy to operate. Simultaneously, the sleeve structure allows the operator to control both the rotary wrench 30 and the anti-rotation wrench 40 at the same time, achieving synchronous rotation of the nut 22 and fixing of the spoke 10, thus improving assembly efficiency.

[0089] As one aspect of this utility model embodiment, the improved connecting structure of the aforementioned wheelset enhances its overall performance and simplifies assembly, while also increasing the torsional strength of the spokes 10 and the lacing tension. Furthermore, as another aspect of this utility model embodiment, the aforementioned bicycle utilizes the aforementioned wheelset, resulting in improved overall bicycle performance and user experience due to the enhanced wheelset performance.

[0090] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
