Description

Technical Field

[0001] The utility model relates to the technical field of bicycles, in particular to an adjusting mechanism for preventing the loosening of a bicycle chain. Background Technique

[0002] A bicycle, also known as a pedal bike or a bicycle, is usually a small two-wheeled land vehicle. After a person rides on the bike, it uses the pedals as power and is a green and environmentally friendly means of transportation.

[0003] When riding a bicycle, if it encounters a bumpy road condition, it is extremely easy to cause the separation between the bicycle chain and the gear disc, resulting in the inability to ride the bicycle normally. And after a long time of riding the bicycle, it is also easy to cause the chain to loosen, and the chain is more likely to loosen. For this reason, we propose an adjusting mechanism for preventing the loosening of a bicycle chain. Content of the Utility Model

The adjusting mechanism is used to adjust the left and right positions of the connecting mechanism. One side of the connecting mechanism is fixedly installed with an anti-detachment mechanism for preventing the bicycle chain from falling off. One side of the anti-detachment mechanism is provided with a tensioning mechanism for tensioning the bicycle chain.

[0024] Among them, the connecting mechanism 3 is sleeved on the outer surface of the adjusting screw 10, and then the positions of the two sets of first locking nuts 11 on the adjusting screw 10 are adjusted, so that the two sets of first locking nuts 11 can be used to fix the connecting mechanism 3, so that the anti-slip mechanism 4 can be located above the chain that needs to be anti-slipped and positioned.

[0025] See also Figure 1 and Figure 2 The connecting mechanism 3 includes a connecting plate 12 and an adjusting groove 13. The connecting plate 12 is sleeved on the outer surface of the adjusting screw 10 and is located between the two groups of first locking nuts 11. A rectangular adjusting groove 13 is opened on the connecting plate 12. A second hexagon socket bolt 14 is inserted into the position of the anti-slipping mechanism 4 corresponding to the adjusting groove 13.
