Rear frame anti-vibration structure ", the anti-vibration structure include front truck link block, bolt, front truck connecting rod, block plate, helical spring,
Shock-absorbing connection is bolted block, main force rod, main force's connection spreader, triangle joint spreader and rear-wheel link block, described to block plate
It is fixed on the lower end of front truck connecting rod, described to be bolted block connection main force rod, the main force rod, which is inlayed, is connected to main force's connection
The left upper end of the centre of spreader, main force's connection spreader is provided with mud guard, and the triangle joint spreader is in the 4th bolt
Connection under be fixed on main force's connection spreader, rear-wheel link block connection triangle joint foundation and triangle joint spreader, and
The 5th bolt is provided on rear-wheel link block, although the shock absorbing apparatus using the effect of spring buffer so that the vibration of bicycle
It reduces, plays the purpose of bumper and absorbing shock, still, spring forms the structure of straight barrel type using the equal steel wire spiral winding of outer diameter,
So that the suspension stroke after spring is compressed is short, so that shock-proof effect is not good enough.
Therefore, it is necessary to the shock absorbing apparatus to existing bicycle to be improved further.
Utility model content
For the current state of the art, the technical problem to be solved by the utility model is to provide one kind by increasing shock-absorbing
Stroke, to increase the shock absorbing apparatus of the bicycle of shock-proof effect.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of shock absorbing apparatus of bicycle, packet
It includes and is arranged on the vehicle frame of bicycle and retractable shock-absorbing part and the shock-proof spring being set on the shock-absorbing part, first gear
Ring and the second baffle ring, the shock-proof spring is between the first baffle ring and the second baffle ring, and the both ends of shock-proof spring are respectively with
One baffle ring and the second baffle ring offset, it is characterised in that: the outer diameter of the shock-proof spring is gradually reduced from interlude to both ends.
There are many structure types of shock-absorbing part, it is preferable that the shock-absorbing part includes casing and inserted link, the inserted link part
It is inserted in casing and can be axially moved with respect to the casing, the first baffle ring fixing sleeve is located on casing, second baffle ring
Fixation is set on the inserted link.
Casing and the first baffle ring are fixedly connected there are many modes, it is preferable that be provided on the periphery wall of described sleeve pipe with
The external screw thread that the internal screw thread of first baffle ring matches.
There are many setting positions of shock-absorbing part, it is preferable that described sleeve pipe is connected on the cushion rod of vehicle frame, and the inserted link connects
It connects in the rear wheel bar of vehicle frame.
Compared with the prior art, the advantages of the utility model are: the shock-proof spring of the shock absorbing apparatus of the bicycle is outer
Diameter size is gradually reduced from interlude to both ends, in this way, when shock-proof spring is compressed, the lesser circle portion in the both ends of shock-proof spring
It is compressed to inner side of the in-between section compared with great circle portion, biggish deflection can be obtained, to increase shock-proof spring energy
Compressed suspension stroke, and then improve the absorbing shock performance of shock-proof spring.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the structural schematic diagram of shock absorbing apparatus in Fig. 1；
The cross-sectional view that Fig. 3 is Fig. 2 (shock-proof spring is in and is uncompressed under state)；
Fig. 4 is the cross-sectional view of Fig. 2 (shock-proof spring is under compressive state).
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in Figures 1 to 4, the shock absorbing apparatus of the bicycle of the utility model embodiment includes shock-absorbing part 1 and set
Shock-proof spring 2, the first baffle ring 3 and the second baffle ring 4 being located on the shock-absorbing part 1, wherein
Shock-absorbing part 1 is arranged between the cushion rod 51 and rear wheel bar 52 of the vehicle frame 5 of bicycle and flexible is specifically kept away
Shake part 1 includes casing 11 and inserted link 12, and 12 part of inserted link is inserted in casing 11 and can axially move with respect to the casing 11,
Casing 11 is connected on the cushion rod 51 of vehicle frame 5, and inserted link 12 is connected in the rear wheel bar 52 of vehicle frame 5, and rear wheel bar 52 is from front to back
It tilts gradually downward, specifically, casing 11 is connected on cushion rod 51 by mounting plate 511, right on casing 11 and mounting plate 511
