Description

Technical Field

[0001] This utility model relates to the field of bicycle hub technology, and in particular to a bicycle hub that prevents reverse rotation. Background Technology

[0002] A roto-stop hub is a specially designed bicycle hub that prevents the wheel from spinning backwards. This design is typically used to fix the wheel in place, such as when the bicycle is stationary for maintenance, repair, or parking. Roto-stop hubs are usually ratchet hubs.

[0003] During prolonged riding, the bearings and ratchet teeth inside the hub may dry out due to lack of lubrication, resulting in loud noise and affecting the rider's riding experience. Therefore, the hub needs to be maintained and lubricated frequently. However, during maintenance, the rider needs to disassemble each component inside the hub, including the ratchet, bearings, and ratchet teeth, apply lubricant, and then reassemble them. This maintenance is quite troublesome and may also cause the components to be installed incorrectly, affecting subsequent normal riding and causing unnecessary trouble. Therefore, this application proposes a reverse anti-rotation bicycle hub. Utility Model Content

[0004] The purpose of this invention is to address the problems in the prior art where maintenance is cumbersome and component installation may be incorrect, affecting subsequent normal riding, by proposing a reverse-rotation anti-rotation bicycle hub.

[0005] The technical solution of this utility model: A bicycle hub with anti-rotation capability, comprising a central shaft, on which a hub body and a ratchet assembly are sleeved, and further comprising:

[0006] A groove is formed on the central axis, and a slider is slidably installed in the groove;

[0007] A lubrication device, which is disposed on the slider, is used for lubrication of the internal components of the hub body;

[0008] An auxiliary mechanism is provided on the lubrication device for convenient spraying of lubricating oil.

[0009] Optionally, the ratchet assembly includes a ratchet housing, a ratchet, and a permanent magnet, wherein the permanent magnet is connected to the ratchet, and the ratchet is pressed into the hub body.

[0010] Optionally, the ratchet includes a first ratchet plate and a second ratchet plate, and the permanent magnet is disposed between the first ratchet plate and the second ratchet plate.

[0011] Optionally, the lubrication device includes a support rod fixedly mounted on the slider, a storage ring connected to the support rod, a storage ring containing lubricating oil, and a plurality of outlet holes on the storage ring.

[0012] Optionally, the slider is provided with a pull rod, and the bottom end of the pull rod is fixedly connected to the top end of the slider.

[0013] Optionally, the auxiliary mechanism includes a telescopic bladder disposed on the inner wall of the storage ring, with an air tube fixedly connected to the top of the telescopic bladder, and a compression plug disposed inside the air tube.

[0014] Optionally, an injection tube is fixedly installed at the top of the storage ring, and a sealing cap is provided on the injection tube.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] This invention, by setting up a sliding groove, a sliding block, a support rod, a storage ring, and an injection pipe, avoids direct contact between personnel and the lubricant during maintenance work. The sliding of the sliding block can drive the movement of the storage ring, making it convenient to apply lubricant to the components that need maintenance, thus increasing the flexibility and adaptability of the device.

[0017] Furthermore, by setting up a telescopic bladder, a compression plug, an air tube, and an outlet, the compression plug compresses the air tube, allowing the telescopic bladder to expand and squeeze the lubricating oil inside the storage ring, and then discharge this lubricating oil from the outlet. This allows for better and more even application of the lubricating oil to the inner wall of the components that need maintenance, extending the service life of the device, reducing noise, and improving the rider's riding experience.

[0018] In summary, this invention enables lubrication and maintenance of components without disassembling the internal parts of the hub, improving maintenance efficiency, extending the service life of the components, reducing noise, and enhancing the rider's riding experience.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] like Figure 1-3 As shown, the present invention proposes a bicycle hub with a reverse rotation stop, including a central shaft 1, a hub body 2 and a ratchet assembly 3 sleeved on the central shaft 1, and a sliding groove 4 opened on the central shaft 1. A slider 5 is slidably installed in the sliding groove 4, and the slider 5 can slide up and down on the sliding groove 4.

[0031] In addition, a pull rod 12 is provided on the slider 5. The bottom end of the pull rod 12 is fixedly connected to the top end of the slider 5. The slider 5 is driven to slide by pulling the pull rod 12. The pull rod 12 provides a tension point, making the movement of the slider 5 effortless and easy.

[0032] It is worth noting that the ratchet assembly 3 includes a ratchet housing 301, a ratchet, and a permanent magnet 302. The permanent magnet 302 is connected to the ratchet, and the ratchet is pressed into the hub body 2. The ratchet includes a first ratchet plate 303 and a second ratchet plate 304. The permanent magnet 302 is disposed between the first ratchet plate 303 and the second ratchet plate 304. The ratchet assembly 3 also includes a check valve. When the hub body 2 and the ratchet housing 301 are connected, the check valve and the ratchet teeth of the ratchet engage and abut.

[0033] like Figure 2-4 As shown, the device also includes a lubrication device, which is installed on the slider 5 for lubricating the internal components of the hub body 2. The lubrication device includes a support rod 6 fixedly installed on the slider 5, a storage ring 13 connected to the support rod 6, a storage ring 13 containing lubricating oil, a plurality of outlet holes 8 on the storage ring 13, an injection pipe 7 fixedly installed at the top of the storage ring 13, and a sealing cap on the injection pipe 7. Lubricating oil is injected into the storage ring 13 through the injection pipe 7, and subsequent lubricating oil can slide out through the outlet holes 8 to coat the inner wall of the internal components.

[0034] Furthermore, by using the sliding of slider 5 to drive the movement of storage ring 13, the position of the lubricating oil can be adjusted during application, resulting in more even application and increasing the flexibility and adaptability of the device.

[0035] like Figure 3 and Figure 4As shown, the device also includes an auxiliary mechanism, which is set on the lubrication device for convenient spraying of lubricating oil. The auxiliary mechanism includes a telescopic bladder 11 set on the inner wall of the storage ring 13. The inner wall of the storage ring 13 is hollow, and this hollow structure is filled by the telescopic bladder 11. The telescopic bladder 11 has a rubber layer on the side facing the outlet hole 8.

[0036] Furthermore, an air tube 9 is fixedly connected to the top of the telescopic bladder 11, and a compression plug 10 is installed inside the air tube 9. The compression plug 10 compresses the air tube 9, causing the pressure to expand the telescopic bladder 11, which can squeeze the lubricating oil out of the outlet 8 and apply it to the inside of the component.

[0037] The working principle of this embodiment is as follows: When the hub needs maintenance, lubricating oil is first successfully injected into the storage ring 13 through the injection tube 7, so that the lubricating oil in the storage ring 13 is sufficient and adequate. After filling, the pull rod 12 is pulled to make the slider 5 slide on the slide groove 4. The position height of the storage ring 13 is adjusted so that the storage ring 13 can be moved next to the component that needs maintenance. At this time, the compression plug 10 is pressed, so that the compression plug 10 compresses the air tube 9, so that the pressure can open the telescopic bladder 11, so that the telescopic bladder 11 squeezes the lubricating oil in the storage ring 13 and squeezes the lubricating oil out of the outlet hole 8, and evenly spreads it on the component that needs maintenance, which extends the service life of the device, reduces noise, and improves the rider's riding experience.

[0038] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
