Detailed Implementation

[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0028] Please see Figures 1 to 3 This utility model provides an auxiliary device for adding spokes to a wheel hub, including a support plate 100, a clamping member 200 and a support block 300.

[0029] Specifically, the clamping member 200 is disposed on the support plate 100 and is used to clamp and fix the hub of the wheel to the support plate 100. There are multiple support blocks 300, which are arranged circumferentially on the support plate 100 with the clamping member 200 as the center. The top surface of the support block 300 is provided with a slot 310, and the bottom of the wheel hub retainer can be engaged in the slot 310.

[0030] In use, first place the hub on the support plate 100, then clamp and fix the hub with the clamp 200. Next, sequentially insert the hub retainer into the retainer groove 310 to complete the positioning of the hub and retainer. Then, manually connect the first end of the spoke to the corresponding hole of the hub. Then, insert the other end of the spoke into the corresponding hole of the retainer to complete the installation of one spoke. Then, use the same method to complete the installation of all spokes.

[0031] The aforementioned wheel hub spokes are equipped with auxiliary devices. By fixing the positions of the hubs (200 pairs of clamping parts) and the retaining rings (300 pairs of support blocks), the hubs and retaining rings can be prevented from sliding arbitrarily during spoke installation, which could cause misalignment of the spokes and affect the installation progress.

[0032] In practical implementation, to prevent the retaining ring from being scratched, an elastic pad can be placed on the inner wall of the retaining groove 310 to prevent direct contact between the inner wall of the retaining groove 310 and the retaining ring.

[0033] In this embodiment, the clamping member 200 includes a clamping rod 210 and a linear motion drive member 220. The support plate 100 has a downwardly recessed mounting hole at its center. The top surface of the support plate 100 has a plurality of guide grooves that communicate with the mounting hole at circumferential intervals. A clamping rod 210 is slidably clamped in each guide groove. The linear motion drive member 220 is connected to all the clamping rods 210 and can simultaneously drive all the clamping rods 210 to slide along the guide groove toward the central axis of the mounting hole or slide outward.

[0034] In use, simply activate the linear motion drive 220 to drive all the clamping rods 210 to slide along the guide groove toward the central axis of the mounting hole until the ends of the clamping rods 210 are clamped onto the side wall of the hub, thus fixing the hub.

[0035] In practice, to prevent the clamping rod 210 from damaging the surface of the hub, an anti-slip pad can be installed at the end of the clamping rod 210.

[0036] In this embodiment, the linear motion drive 220 includes a rotary power source 221, a drive ring 222, and a insertion rod 223. The drive ring 222 is rotatably mounted on the support plate 100. The drive ring 222 has multiple arc-shaped first grooves spaced circumferentially, with one end of each groove offset towards its central hole. Each clamping rod 210 has an insertion rod 223 at its end, which slidably inserts into the first groove. The rotary power source 221 is connected to the drive ring 222 and drives the drive ring 222 to rotate. When the drive ring 222 rotates, it can drive the clamping rod 210 to slide inward or outward along the guide groove via the first groove.

[0037] In use, simply start the rotary power source 221 to drive the drive ring 222 to rotate. Through the first slide groove, guide groove and insert rod 223, the clamp rod 210 can be driven to slide along the guide groove.

[0038] In this embodiment, the rotary power source 221 includes a handle 2211 and a tightening screw 2212. The handle 2211 is disposed on the outer wall of the drive ring 222, and the tightening screw 2212 is threadedly connected to the drive ring 222. When the tightening screw 2212 is rotated, the end of the tightening screw 2212 can pass through the drive ring 222 and abut against the support plate 100.

[0039] In use, first loosen the tightening screw 2212 to allow the drive ring 222 to be in its natural state. Then, the handle 2211 can be used to rotate the drive ring 222. When the clamping rod 210 reaches the desired position, stop rotating the drive ring 222 and lock it in place using the tightening screw 2212. Of course, in other embodiments, the rotational power source 221 can be other types, such as belt pulleys, sprockets, or other transmission methods.

[0040] In a preferred embodiment, the device further includes a radial push-pull member 400, and a support block 300 is freely placed on the support plate 100. There are multiple radial push-pull members 400, and the multiple radial push-pull members 400 are arranged and connected in a one-to-one correspondence with the multiple support blocks 300. The radial push-pull members 400 can provide elastic force to the support block 300 along the radial direction of the support plate 100.

[0041] When using the device, gently pull the retaining ring outwards when threading the spoke end. Once the spoke end is aligned with the hole on the retaining ring, release the retaining ring. The radial push-pull component 400 can apply radial elastic force to the retaining ring to reset it, allowing the spoke end to be smoothly inserted into the hole.

[0042] Specifically, the radial push-pull member 400 includes a fixing block 410 and an elastic member 420. The fixing block 410 is fixed to the support plate 100 and is located on the outer side relative to the support block 300. The elastic member 420 is arranged radially along the support plate 100 and connects the support block 300 and the fixing block 410. When the retaining ring moves, the elastic member 420 contracts or returns accordingly, facilitating the movement and reset of the retaining ring.

[0043] Furthermore, the number of support blocks 300 is even, and the number of radial push-pull parts 400 that are matched with them is also even.

[0044] An even number of support blocks ensures that each of the 300 support blocks is set in pairs, which ensures that the clamp ring is always subjected to force in its radial direction when pulled, thus avoiding large-scale shaking of the clamp ring.

[0045] By using the aforementioned auxiliary device for the hub spokes, and fixing the position of the hub and rim with the clamping component 200, it is possible to prevent the hub and rim from sliding arbitrarily during the spoke installation process, which could cause the spokes to be misaligned and affect the installation progress.

[0046] Meanwhile, the radial push-pull element 400 further facilitates the insertion of the spoke tail end, thereby further improving installation efficiency.
