Description
Technical Field
[0001] The utility model relates to the technical field of bicycle chains, in particular to a wear-resistant and high-strength bicycle chain. Background Technique
[0002] A bicycle chain is a common transmission device. A bicycle chain is composed of a series of chain links. Each chain link is equipped with two side plates and is firmly connected together by rivets. It is a key component of the transmission system and is mainly used to transmit power. It transmits the power of pedaling to the rear wheel by meshing with the chainring and the freewheel, so that the bicycle moves forward. During this period, the pin and the sleeve constantly contact the gear and are affected by more vibrations. At the same time, the chain is also pulled, and different chain links may touch each other. As a bicycle traveling on the road, a road bike has a relatively high traveling speed, and its chain strength also needs to be relatively high to ensure its service life. The following problems exist in the prior art:
[0003] Because the existing road bikes have a relatively high traveling speed and have relatively high requirements for the chain, and the chain bears a relatively large strength, it is easy for the chain links and the rivets to become loose during a long-term cycling process, resulting in the problem that the chain is separated and detached from the chainring. At the same time, the existing road bike chains are mainly exposed to the air. When parked for a long time or ridden in a place with a lot of dust, dirt and dust will accumulate on the chain and may enter the gap between the rivet and the chain link during the transmission of the chain, resulting in increased wear between the rivet and the chain link, and finally problems such as abnormal noise or unsmooth transmission occur. Content of the Utility Model
[0004] The utility model provides a wear-resistant and high-strength bicycle chain to solve the problems raised in the above background technique.

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] As Figure 1 、 Figure 2 shown, the present utility model provides a wear-resistant and high-strength bicycle chain, including a link mechanism 1. Protection mechanisms 2 are arranged on both the left and right sides of the link mechanism 1. A strengthening mechanism 3 is arranged on the top of the protection mechanism 2. The link mechanism 1 includes two chain plates 11. Two rivet grooves 12 are opened on the opposite surfaces of the two chain plates 11. Two rivets 13 are arranged between the opposite surfaces of the two chain plates 11. The left and right ends of the two rivets 13 respectively penetrate into the two rivet grooves 12 opened on the left and right chain plates 11. Two connecting chain plates 14 are sleeved on the outer walls of the two rivets 13. A rolling ring 15 is sleeved in the middle of the outer walls of the two rivets 13. The rolling ring 15 is located between the two connecting chain plates 14.
[0023] As Figure 3As shown in the figure, both of the two protection mechanisms 2 include protection reinforcement plates 21. The two protection reinforcement plates 21 are respectively located on the opposite sides of the two chain plates 11. Two threaded mounting holes 22 are opened on the side of the protection reinforcement plate 21 away from the chain plate 11. A through hole 23 that penetrates left and right is opened in the two threaded mounting holes 22. A threaded disc 24 is threadedly mounted on the inner ring of the threaded mounting hole 22. A transverse groove 25 is opened on the side of the threaded disc 24 away from the protection reinforcement plate 21. A clamping block 26 is fixedly mounted on the side of the threaded disc 24 close to the protection reinforcement plate 21. A sealing ring 27 is fixedly mounted on the outer wall of the clamping block 26. Rivet holes 131 are opened at both the left and right ends of the rivet 13. One end of the clamping block 26 close to the chain plate 11 penetrates through the through hole 23 and is clamped with the rivet hole 131;
[0024] First, put the two protection reinforcement plates 21 on the two chain plates 11, align the through hole 23 with the rivet holes 131 opened at both the left and right ends of the rivet 13. Then, a flat-head screwdriver can be inserted into the transverse groove 25 opened in the threaded disc 24, and the threaded disc 24 is aligned with the threaded mounting hole 22 and rotated until the clamping block 26 passes through the through hole 23 and is clamped into the rivet hole 131 opened in the rivet 13, and the sealing ring 27 is used to improve the stability after clamping. The two protection reinforcement plates 21 can well block the gap between the rivet 13 and the protection reinforcement plate 21. At the same time, after tightening the threaded disc 24, the tightness between the two chain plates 11 can also be improved to avoid loosening.
[0025] As Figure 4 、 Figure 5 As shown in the figure, the strengthening mechanism 3 includes a protection top plate 31. The protection top plate 31 is fixedly mounted on the tops of the two protection reinforcement plates 21. An anti-chain-breaking mechanism 32 is arranged on the top of the protection top plate 31. Arc-shaped plates 311 are fixedly mounted at both the front and rear ends of the protection top plate 31. The two arc-shaped plates 311 are respectively lapped on the front and rear sides of the top of the chain plate 11. The anti-chain-breaking mechanism 32 includes a bolt cap 321. A metal connection belt 322 is fixedly connected between the opposite surfaces of the bolt caps 321 on the tops of the front and rear adjacent protection reinforcement plates 21. A bolt 323 is fixedly mounted at the bottom of the bolt cap 321. A threaded hole 312 is opened at the center of the top of the protection top plate 31. The bolt 323 is threadedly connected with the threaded hole 312;
[0026] After the protection reinforcement plate 21 is installed, the protection top plate 31 can block the gap between the chain plate 11 and the connecting chain plate 14 by means of the two arc-shaped plates 311. At the same time, it can also prevent the surface of the chain from being worn when the road bicycle falls to the ground. Then, the two bolt caps 321 are respectively fixed on the protection top plate 31 at the tops of the two chain plates 11 included in the two chain link mechanisms 1, and are fixed by the threaded connection between the bolt 323 and the threaded hole 312. Thus, the connection stability between the front and rear two chain link mechanisms 1 can be strengthened by the metal connection belt 322 to avoid the chain from breaking due to a large tensile force during high-speed driving.
[0027] The working principle of the wear-resistant and high-strength bicycle chain will be specifically described below.
[0028] As Figures 1 - 5 shown, a complete chain can be formed by multiple link mechanisms 1. At the same time, the connecting link plate 14 is sleeved on the outer wall of the rivet 13 to ensure the flexibility of meshing, and the rivet 13 is used to ensure the stability between the two rivet grooves 12. At the same time, the rolling ring 15 between the two connecting link plates 14 contacts the chainring to avoid excessive wear and improve smoothness. At the same time, first, the two protective reinforcement plates 21 are sleeved on the two link plates 11, aligning the through holes 23 with the rivet holes 131 opened at the left and right ends of the rivet 13. Then, a flat-head screwdriver can be inserted into the transverse groove 25 opened in the threaded disc 24, and the threaded disc 24 is aligned with the threaded mounting hole 22 and rotated until the locking block 26 passes through the through hole 23 and is locked into the rivet hole 131 opened in the rivet 13, and the sealing ring 27 is used to improve the stability after locking. The two protective reinforcement plates 21 can well block the gap between the rivet 13 and the protective reinforcement plate 21. At the same time, after tightening the threaded disc 24, the tightness between the two link plates 11 can also be improved to avoid loosening. At the same time, after the protective reinforcement plate 21 is installed, the protective top plate 31 can block the gap between the link plate 11 and the connecting link plate 14 by using the two arc plates 311, and at the same time, it can also prevent the surface of the chain from being worn when the road bicycle falls to the ground. Then, the two bolt caps 321 are respectively fixed on the protective top plate 31 at the top of the two link plates 11 included in the two link mechanisms 1, and fixed by the threaded connection of the bolt 323 and the threaded hole 312, so that the connection stability between the front and rear two link mechanisms 1 can be strengthened by the metal connection belt 322 to avoid chain breakage caused by a large tensile force during high-speed driving.
[0029] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit and idea of the present utility model are within the protection scope of the present utility model.
