Technical field

The utility model relates to a kind of body frame structure for automotive, be specifically related to a kind of shock-absorptive frame of bicycle.

Background technology

Cycle frame, as the skeleton of whole bicycle, has farthest determined, has affected correctness and the traveling comfort of riding posture.On general vehicle frame, shock absorption device is all installed, but damping effect is not good, and body frame structure for automotive is not novel, intensity is low, and safety is not high.

Utility model content

For the deficiency existing in prior art, the utility model object is to be to provide a kind of shock-absorptive frame of bicycle, novel structure, and intensity is high, and good damping effect is practical.

To achieve these goals, the utility model is to realize by the following technical solutions: a kind of shock-absorptive frame of bicycle, comprise pipe, upper intermediate tube, Seat stay, Chain stay, lower pipe, lower intermediate tube, first pipe, permanent seat, bumper, bearing and reinforced tube, Seat stay is all connected with upper pipe postmedian by rotating shaft with lower pipe upper end, between Seat stay and lower pipe lower end, be connected with Chain stay, upper pipe front end is provided with first pipe, upper pipe afterbody is provided with upper intermediate tube, on upper intermediate tube, be provided with permanent seat, permanent seat is connected with bumper one end, the bumper other end is connected with bearing, bearing is connected with lower pipe middle part by reinforced tube, bearing is also connected with five-way by lower intermediate tube.

On described Seat stay, be disposed with bridge tube, C type wire seat, brake mount, disc brake fetching from top to bottom.

Described Chain stay two ends are respectively arranged with rear hook and five-way, and Chain stay right side is provided with lower bridge tube, and rear hook and Seat stay lower end are fixed, and five-way is also fixedly connected with lower pipe lower end.

On described lower pipe, be provided with lower pipe bridge pipe and lower support pipe.

The utility model novel structure, intensity is high, and good damping effect is practical.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.

With reference to Fig. 1-4, this specific embodiment is by the following technical solutions: a kind of shock-absorptive frame of bicycle, comprise pipe 1, upper intermediate tube 2, Seat stay 3, Chain stay 4, lower pipe 5, lower intermediate tube 6, first pipe 7, permanent seat 8, bumper 9, bearing 10 and reinforced tube 11, Seat stay 3 is all connected with upper pipe 1 postmedian by rotating shaft 11 with lower pipe 5 upper ends, between Seat stay 3 and lower pipe 5 lower ends, be connected with Chain stay 4, upper pipe 1 front end is provided with first pipe 7, upper pipe 1 afterbody is provided with upper intermediate tube 2, on upper intermediate tube 2, be provided with permanent seat 8, permanent seat 8 is connected with bumper 9 one end, bumper 9 other ends are connected with bearing 10, bearing 10 is connected with lower pipe 5 middle parts by reinforced tube 11, bearing 10 is also connected with five-way 12 by lower intermediate tube 6.

It should be noted that on described Seat stay 3 and be disposed with bridge tube 31, C type wire seat 32, brake mount 33, disc brake fetching 34 from top to bottom.

It should be noted that described Chain stay 4 two ends are respectively arranged with rear hook 41 and five-way 12, Chain stay 4 right sides are provided with lower bridge tube 42, and rear hook 41 is fixed with Seat stay 3 lower ends, and five-way 12 is also fixedly connected with lower pipe 5 lower ends.

In addition, on described lower pipe 5, be provided with lower pipe bridge pipe 51 and lower support pipe 52.

This specific embodiment can reach the optimal damping effect of bicycle, also makes the structure of shock-proof cart simplify most; And these combinations are all triangular structures, can increase the intensity of car load; Increase the setting of lower intermediate tube 6, can fill the more Front Derailleur of polytypic, very easy to use.

This specific embodiment novel structure, intensity is high, and good damping effect is practical.

More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
