A new type of bicycle hub

Abstract

This utility model discloses a novel bicycle hub, relating to the field of bicycle hub technology. It includes a hub housing, a freehub base, a hollow shaft, a ratchet, an internal spline, and a bearing. The freehub base is located on one side of the hub housing. By installing the sealing ring, the movable ring is moved, allowing it to contact the vertical rod and the insertion rod during movement. The vertical rod then moves the movable block and insertion rod inside the movable ring, fixing its position and preventing rotation. Simultaneously, after the insertion rod engages with the movable ring, an internal round-headed locking block and a return spring prevent the movable ring from moving. The locking bolt further stabilizes the movable ring after movement, preventing further shifting. Therefore, during use, the bicycle hub not only prevents the sealing ring from loosening due to vibration or impact but also improves the sealing effect through the movable ring.

Description

Technical Field

[0001] This utility model relates to the field of bicycle hub technology, specifically a novel bicycle hub. Background Technology

[0002] As the most important component of a bicycle wheel, the hub largely determines indicators such as riding resistance, the load-bearing capacity of the bicycle, and the durability of the wheel. The hub, commonly known as the hub barrel, is the barrel outside the axle that connects the spokes. It is usually called the axle skin. Depending on the number of spokes, there are generally two types of lacing: 3-spoke and 5-spoke. There are two types of hubs: iron hubs and aluminum hubs.

[0003] When using the aforementioned bicycle hubs, it is necessary to protect the internal bearings, which requires the installation of sealing rings at both ends of the hub. These sealing rings are generally connected by threads. Over time, the vibration and impact of the hub can cause the threads to loosen, making the sealing rings prone to loosening and falling off. This allows external impurities and dust to enter the bearings, causing the grease inside the bearings to deteriorate and affecting the use of the bicycle hub. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of bicycle hub to solve the problem mentioned in the background art that the sealing ring of the bicycle hub is prone to falling off during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel bicycle hub, comprising a hub shell, a freehub base, a hollow shaft, a ratchet, an internal spline, and bearings. A freehub base is provided on one side of the hub shell. A hollow shaft is provided inside the freehub base and the hub shell. A ratchet is provided inside the hub shell. An internal spline is fitted onto the surface of the ratchet. Bearings connected to the hollow shaft are provided inside both the hub shell and the freehub base. Mounting rods are provided at both ends of the hollow shaft. A sealing ring is threaded onto the surface of the mounting rod. A vertical rod is provided at one end of the sealing ring, and the vertical rods are symmetrically distributed at one end of the sealing ring.

[0006] Preferably, the sealing ring has an insert rod at one end near the vertical rod, and the insert rods are symmetrically distributed at one end of the sealing ring.

[0007] Preferably, a movable ring is fitted onto the surface of the sealing ring, a slider is provided inside the movable ring and slidably connected to the sealing ring, and a movable block is provided inside the sealing ring, the movable blocks being symmetrically distributed inside the sealing ring.

[0008] Preferably, a plug rod is connected to one side of the movable block, and a movable seat is provided at one end of the movable block.

[0009] Preferably, a guide rod connected to a sealing ring passes through the interior of the movable seat, the guide rods are symmetrically distributed inside the sealing ring, and a limit spring is provided on the side of the movable seat near the guide rod.

[0010] Preferably, a round-headed locking block is provided at the bottom of the insertion rod, and the round-headed locking blocks are symmetrically distributed inside the insertion rod. A return spring connected to the insertion rod is provided on one side of the round-headed locking block.

[0011] Preferably, the end of the moving ring away from the moving block is provided with a locking bolt that is threadedly connected to the sealing ring, and the locking bolts are symmetrically distributed at one end of the moving ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This new type of bicycle hub, when in use, allows for quick installation of the sealing ring and mounting sleeve via a threaded connection. The sealing ring is then quickly installed at both ends of the hollow axle. After installation, the surface-mounted movable ring is pushed, causing it to contact the vertical rod and insert rod. This allows the movable block to move the insert rod, engaging it with a pre-drilled groove inside the hub housing and freehub. Simultaneously, the insert rod inserts into the movable ring as the vertical rod contacts the movable block. The movable ring's position is then fixed by a round-headed locking block and a return spring. Finally, a locking bolt is installed at the bottom of the movable ring, locking it to the sealing ring and preventing loosening. The insert rod is then inserted into the pre-drilled groove, preventing the sealing ring from loosening due to vibration or impact during use. This design not only prevents the sealing ring from loosening due to vibration or impact but also enhances the sealing effect through the movable ring. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a novel bicycle hub, comprising a hub shell 1, a freehub base 2, a hollow axle 3, a ratchet 4, an internal spline 5, and a bearing 6. The freehub base 2 is located on one side of the hub shell 1. The hollow axle 3 is located inside the freehub base 2 and the hub shell 1. The ratchet 4 is located inside the hub shell 1, and the surface of the ratchet 4 is fitted with an internal spline 5. Bearings 6, which connect to the hollow axle 3, are located inside both the hub shell 1 and the freehub base 2. Mounting rods 7 are located at both ends of the hollow axle 3. The surface of the mounting rods 7 is threaded, and a sealing ring 8 is threaded onto the surface of the mounting rods 7. One end of the sealing ring 8 is... There is a vertical rod 9, which is symmetrically distributed at one end of the sealing ring 8. An insert rod 10 is provided at the end of the sealing ring 8 near the vertical rod 9, which is also symmetrically distributed at one end of the sealing ring 8. A movable ring 11 is sleeved on the surface of the sealing ring 8. A slider 12 is provided inside the movable ring 11 and is slidably connected to the sealing ring 8. The slider 12 is shaped like a "T" and is symmetrically distributed inside the movable ring 11. A groove matching the slider 12 is provided inside the sealing ring 8. A movable block 13 is provided inside the sealing ring 8. The movable block 13 is shaped like a triangle and is symmetrically distributed inside the sealing ring 8.

[0022] This new type of bicycle hub, because the moving block 13 is triangular in shape, allows the vertical rod 9 to be squeezed to one side when it comes into contact with it.

[0023] exist Figure 4 In the middle, a plug rod 14 is connected to one side of the movable block 13, and a movable seat 15 is provided at one end of the movable block 13. A guide rod 16 connected to the sealing ring 8 passes through the inside of the movable seat 15. The guide rod 16 is symmetrically distributed inside the sealing ring 8. A limit spring 17 is provided on the side of the movable seat 15 near the guide rod 16.

[0024] This new type of bicycle hub has a movable block 13 that can move synchronously with the connected plug rod 14 when it moves. After being plugged into the reserved slot, it can limit the movement ring 11. At the same time, the purpose of the limiting spring 17 is to reset the movable seat 15 after the restriction is lost, so that the movable seat 15 can move the connected movable block 13 and plug rod 14.

[0025] exist Figure 5 In the middle, a round-headed locking block 18 is provided at the bottom of the insertion rod 10. The round-headed locking blocks 18 are symmetrically distributed inside the insertion rod 10. A reset spring 19 connected to the insertion rod 10 is provided on one side of the round-headed locking block 18. A locking bolt 20 threadedly connected to the sealing ring 8 is provided at the end of the moving ring 11 away from the moving block 13. The locking bolts 20 are symmetrically distributed at one end of the moving ring 11.

[0026] This novel bicycle hub, when the insert rod 10 contacts the moving ring 11, can compress the round-headed locking block 18 at its bottom end, thereby causing the round-headed locking block 18 to move and retract into the interior of the insert rod 10. It can also compress the return spring 19. After the insert rod 10 is fully inserted, the moving ring 11 has a reserved groove inside that matches the round-headed locking block 18, allowing the round-headed locking block 18 to be unrestricted. Then, the return spring 19 connected on one side can be reset, and after resetting, it can move the round-headed locking block 18 so that the round-headed locking block 18 can engage with the reserved groove, thereby restricting the position of the moving ring 11. By tightening the locking bolt 20, the position of the moving ring 11 on the surface of the sealing ring 8 can be fixed, thereby preventing the sealing ring 8 from loosening.

[0027] When the bicycle hub is in use, the sealing ring 8 can be installed with the mounting sleeve 7 via a threaded connection, allowing the sealing ring 8 to be quickly installed on both ends of the hollow shaft 3. After installation, the moving ring 11 fitted on the surface is pushed, causing it to slide on the surface of the sealing ring 8 via the slider 12. During this movement, the moving ring 11 contacts the vertical rod 9 and the insert rod 10. This contact causes the vertical rod 9 to contact the internally mounted moving block 13, causing it to move. This movement of the moving block 13 then moves the connected insert rod 14 and the bottom-connected moving seat 15, allowing it to slide on the surface of the guide rod 16. This ensures the moving seat 15 moves smoothly during its movement. The mechanism is stable, and when the movable seat 15 moves, it can compress the limiting spring 17 set on one side. At this time, the plug rod 14 and the movable block 13 can be moved to the outside of the movable ring 11, and can be engaged with the reserved slots opened inside the hub housing 1 and the freehub base 2. At the same time, when the vertical rod 9 contacts the movable block 13, the plug rod 10 can be inserted into the interior of the movable ring 11. Then, the position of the movable ring 11 can be fixed by the round head locking block 18 and the reset spring 19. Then, the locking bolt 20 can be installed at the bottom of the movable ring 11, so that the movable ring 11 can be locked with the sealing ring 8 to prevent loosening. At this time, the plug rod 14 is inserted into the reserved slot, so that the sealing ring 8 will not be loosened due to vibration or impact during use. This not only prevents the sealing ring 8 from being loosened due to vibration or impact during use, but also improves the sealing effect through the setting of the movable ring 11.

[0028] In summary, the hub, as the most important component of a bicycle wheel, largely determines indicators such as riding resistance, the load-bearing capacity of the bicycle, and the durability of the wheel. By installing the sealing ring 8, the moving ring 11 is moved so that it can contact the vertical rod 9 and the insertion rod 10 during movement. At this time, the vertical rod 9 can move the moving block 13 and the insertion rod 14 set inside the moving ring 11, thereby fixing the position of the moving ring 11 and preventing it from rotating. At the same time, after the insertion rod 10 is inserted into the moving ring 11, it can prevent the moving ring 11 from moving through the round head locking block 18 and the return spring 19 set inside. The locking bolt 20 locks the moving ring 11 so that it can be stably restricted after movement, preventing it from moving. Thus, when the bicycle hub is in use, it not only prevents the sealing ring 8 from loosening due to vibration or impact, but also improves the sealing effect through the setting of the moving ring 11.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
