Description

Technical Field

[0001] This utility model relates to the field of chain technology, and in particular to a self-lubricating chain. Background Technology

[0002] The bicycle chain is a key component of the bicycle drivetrain. It consists of a series of interconnected links that, in conjunction with sprockets, transmit the rider's power from the pedals to the rear wheel, propelling the bicycle forward. Bicycle chains are typically made of steel or alloys, with different materials varying in strength, weight, and durability. High-quality chains often possess higher strength and better wear resistance.

[0003] In daily use, bicycle chains require regular maintenance to keep them well lubricated and reduce friction and wear. Currently, it is necessary to manually add lubricant to the bicycle chain regularly to reduce chain friction and wear. This method is time-consuming and laborious. In addition, bicycle chains are usually composed of rolling chains and fixed chains. During the bicycle ride, the rolling chain and fixed chain rub against each other, which can easily cause wear to the chain and affect its service life. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a self-lubricating chain, including a support plate 3. A rotating shaft 2 is rotatably connected to the bottom of opposite ends of the support plate 3. A sprocket 1 is fixedly connected to the middle of the rotating shaft 2. A chain is mounted on the outer wall of the sprocket 1. The chain includes a first chain plate 9, a second chain plate 10 disposed on the inner side of the first chain plate 9, and fixing pins 11 disposed on both the left and right sides of the second chain plate 10. The first chain plate 9 and the second chain plate 10 are connected by the fixing pins 11. A graphite ring 12 is disposed on the outer side of the second chain plate 10. The outer side of 12 is in contact with the inner side of the first chain plate 9. The upper side of the opposite end of the support plate 3 is movably connected to the movable plate 4. The left and right sides of the rotating shaft 2 are fixedly connected to the cam 13. The upper part of the cam 13 is provided with the movable rod 14. The movable rod 14 is movably connected to the inside of the support plate 3. The top of the movable rod 14 is fixedly connected to the bottom of the movable plate 4. The lower part of the movable plate 4 is provided with the hollow plate 7. The left and right ends of the hollow plate 7 are fixedly connected to the opposite ends of the support plate 3. The bottom of the hollow plate 7 is equipped with a brush 8, which is in contact with the chain.

[0027] Specifically, graphite rings 12 are provided at the contact ends of the first chain plate 9 and the second chain plate 10. The layered structure of the graphite rings 12 gives them good lubricity, which can effectively reduce friction, improve the lubrication performance of the chain, reduce damage to the chain caused by friction, and improve the service life of the chain. The rotating shaft 2 drives the cam 13 to rotate, and the cam 13, together with the movable rod 14, drives the movable plate 4 to move up and down. The movable plate 4 drives the conical piston 16 to move up and down through the fixed tube 17, so that the lubricant inside the lubricant storage tank 6 enters the interior of the conical piston 16, and enters the interior of the hollow plate 7 through the fixed tube 17 and the conical piston 16. The lubricant permeates to the surface of the brush 8 through the permeation hole at the bottom of the hollow plate 7, and the brush 8 applies the lubricant to the link.

[0028] Reference Figure 5 A connecting plate 5 is fixedly connected to the top of the support plate 3. A lubricant storage tank 6 is provided in the middle of the connecting plate 5. A top cover is provided at the top of the lubricant storage tank 6. A sealing ring 15 is provided at the bottom of the lubricant storage tank 6. The bottom of the lubricant storage tank 6 is shaped like an inverted frustum. A conical piston 16 is movably connected to the bottom of the lubricant storage tank 6. The conical surface of the conical piston 16 fits against the inner wall of the lubricant storage tank 6 and is provided with a water inlet hole. A fixing tube 17 is fixedly connected to the bottom of the conical piston 16. The outer wall of the bottom of the fixing tube 17 is provided with threads. A ring 18 is fixedly connected to the middle of the fixing tube 17. The bottom of the fixing tube 17 passes through the middle of the movable plate 4.

[0029] Specifically, the bottom of the lubricant storage tank 6 is shaped like an inverted truncated cone. The conical piston 16 is connected to the movable plate 4 and the movable rod 14 through the fixed tube 17. Under the action of gravity, the conical piston 16 is tightly attached to the inner wall of the lubricant storage tank 6. Therefore, the lubricant inside the lubricant storage tank 6 cannot flow out through the water inlet hole opened on the conical surface of the conical piston 16. When the cam 13 cooperates with the movable rod 14 to drive the movable plate 4 to rise, the movable plate 4 drives the conical piston 16 to rise through the fixed tube 17, so that the conical piston 16 is completely exposed to the lubricant liquid. At this time, the lubricant will enter the interior of the conical piston 16 through the water inlet hole and flow out.

[0030] Reference Figure 6 A connecting pipe 19 is fixedly connected to the upper end of the hollow plate 7, and a threaded connector 20 is fixedly connected to the other end of the connecting pipe 19. The threaded connector 20 is threadedly connected to the bottom end of the fixed pipe 17. The bottom end of the ring 18 is in contact with the top end of the movable plate 4, and the top end of the threaded connector 20 is in contact with the bottom end of the movable plate 4.

[0031] Specifically, the ring 18 and the threaded connector 20 work together to fix the fixed tube 17 and the movable plate 4, so that the movable plate 4 can drive the fixed tube 17 to move up and down, and then drive the conical piston 16 to move.

[0032] Working principle: The rotating shaft 2 is connected to the bicycle pedal. When the bicycle is moving, the rotating shaft 2 is driven to rotate by the pedal. The rotating shaft 2 drives the cam 13 to rotate. The cam 13, together with the movable rod 14, drives the movable plate 4 to rise and fall. The movable plate 4 drives the conical piston 16 to move up and down inside the lubricant storage tank 6 through the fixed tube 17. When the conical piston 16 rises, the lubricant enters the fixed tube 17 through the water inlet hole set on its conical surface and enters the interior of the connecting tube 19 through the connecting tube 19. The lubricant permeates from the bottom end of the connecting tube 19 to the surface of the brush 8. The brush 8 evenly applies the lubricant to the surface of the chain for lubrication.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
