Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, a bicycle chain auxiliary device capable of accurately butting chain hole tracks comprises a movable shaft 1, a channel 2 is arranged in the inner side wall of the movable shaft 1, an arc-shaped ring 3 is arranged in an interlayer at the outer side wall of the movable shaft 1, an elastic rod 8 is arranged at the arc-shaped side wall of the arc-shaped ring 3, a compression spring 9 is fixedly connected to the bottom side of the elastic rod 8, the bottom end of the compression spring 9 is elastically connected to the top side wall of the arc-shaped ring 3, a cover hook 4 penetrates through the side wall of the arc-shaped ring 3, a convex block 5 is fixedly connected to the top side of the cover hook 4, a through button 6 is fixedly connected to the top end of the convex block 5, a support column 13 is fixedly connected to the top end of the arc-shaped ring 3, a connecting cable 12 is fixedly connected to the axis center of the side end of the support column 13, a rolling shaft 7 is arranged at the top end of the connecting cable 12, the top end of the side wall of the convex block 5 is penetrated with a movable ring 10, and the outer side wall of the convex block 5 is penetrated with an elastic ring 11.

The top end of the connecting cable 12 is rotatably connected to two ends of the rolling shaft 7, and the axis of the side wall of the rolling shaft 7 can rotate around the side wall of the connecting cable 12.

Wherein, the middle section of the side wall of the pull rope 14 penetrates through the inner side wall of the elastic rod 8, and when the side wall of the elastic rod 8 is arched upwards, the exposed distance of the pull rope 14 can be shortened.

Wherein, the end of the rotating plate 15 far away from the rolling shaft 7 is clamped in the side wall crack of the elastic ring 11, and when the top side of the elastic ring 11 is bounced upwards, the rotating plate 15 can be driven to be bounced upwards.

When the top end of the movable ring 10 is located at the top end of the elastic ring 11, and the side wall of the movable ring 10 presses the top side of the elastic ring 11 upwards, it means that the side of the movable shaft 1 rotates to the side with the largest extrusion force at this time.

Wherein, the side wall of the through button 6 is provided with adsorptive sponge, when the side wall of the movable ring 10 passes back and forth, the side wall of the through button 6 can be wiped back and forth, the soil splashed in rainy season can be removed, and the side wall of the movable ring 10 is prevented from being bonded into blocks.

Wherein, both ends of the elastic rod 8 are fixedly connected to the bottom side wall of the supporting column 13, and when the middle bottom side wall of the elastic rod 8 is arched upwards, the positions of both ends thereof are used as supporting points according to the side wall of the supporting column 13.

The pull rope 14 is positioned on the rolling shaft 7 and surrounds the rolling shaft in the direction of the convex block 5, and when the side wall of the pull rope 14 is dragged, the rolling shaft 7 can be conveniently driven to rotate in the direction of the convex block 5.

The working principle is as follows: when the chain is used, as shown in fig. 1 and 4, when the inner side wall of the hole movable ring 10 on the chain penetrates to the top of the bump 5 along with the rotation of the chain, the pressure applied by the side wall of the chain at the side wall of the movable shaft 1 is gradually increased along with the rotation of the movable shaft 1, and the inner side wall of the movable shaft 1 is tightened, that is, the outer side wall of the arc-shaped ring 3 is tightened;

at this time, the movable ring 10 approaches the side wall of the elastic rod 8, when the side wall of the movable ring 10 pushes the side wall of the elastic ring 11 inwards to compress inwards, the side wall of the elastic ring 11 drags the rotating plate 15 downwards (as shown in fig. 4), the side wall of the rolling shaft 7 is driven to rotate at this time, the rotating direction of the rolling shaft 7 rotates towards the direction of the bump 5, so that the inner side wall of the movable ring 10 can slide along the side wall of the rotating plate 15 when being sleeved in the bump 5, and the chain can be prevented from falling off when being butted;

as shown in fig. 2-4, after the movable shaft 1 rotates, the chain gradually separates from the side wall of the movable shaft 1, and the side wall of the cover hook 4 loses the extrusion of the movable ring 10 and then can recover to the upward arched state, the top side of the cover hook 4 jacks up the projection 5, and the elastic rod 8 at the bottom side of the cover hook 4 is also popped up upwards by the action force of the bottom side compression spring 9 and is attached to the bottom side of the cover hook 4;

after the pull rope 14 in the inner side of the elastic rod 8 loses a part of limited force, the side wall of the rolling shaft 7 returns to rotate, and the side wall of the rotating plate 15 is adjusted to the topmost part of the side wall of the lug 5, so that the inner ring of the movable ring 10 can be butted accurately in the next rotation.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
