Abstract

The utility model discloses a vibration absorbing bicycle frame which comprises a seat supporting pipe. The seat supporting pipe is fixedly connected with an upper pipe; arc bend is arranged on the upper pipe close to the seat supporting pipe; the upper pipe is fixedly connected with the upper part of a head pipe; the lower part of the head pipe is fixedly connected with a lower pipe; a supporting pipe is arranged between the upper pipe and the lower pipe; the lower pipe is fixedly connected with a middle pipe; an elastic component is arranged between the middle pipe and the lower pipe; two ends of the middle pipe are respectively connected with an rear upper fork and a rear lower fork; and a knuckle is connected on the rear upper fork and the rear lower fork at one end far from the middle pipe. The vibration absorbing bicycle frame can ensure that vibration is absorbed by the elastic component through elastic deformation, effectively reduces the vibration sensation of a person who rides a bicycle, and improves the riding comfort level.

Description

A kind of Shockproof type bicycle rack

Technical field

The utility model relates to a kind of bicycle rack, relates in particular to a kind of Shockproof type bicycle rack.

Background technology

Bicycle has become the indispensable vehicle in people's daily life, bicycle is made up of parts such as vehicle frame, tire, foot-operated, brake, chains, wherein vehicle frame is the skeleton of bicycle, it is the basic structure body that constitutes bicycle, miscellaneous part all is directly or indirectly to be installed on the vehicle frame, and vehicle frame generally adopts the normal carbon copper pipe through welding, combining., in daily driving process, run into and jolt and impact is inevitably as the vehicle, therefore directly influence the performance of car load as its shock-absorbing performance of vehicle frame of main load bearing component.

The utility model content

The utility model provides a kind of Shockproof type bicycle rack, can effectively must alleviate the vibrations in travelling.

The technical solution of the utility model is: a kind of Shockproof type bicycle rack, comprise the seat support tube, manage on the seat support tube captive joint, last pipe is provided with arc-shaped bend near described seat support tube place, the top of last pipe fixed connector pipe, the bottom captive joint of pipe is pipe down, be provided with support tube between the top tube and down tube, under manage in the captive joint and manage, be provided with elastomeric element between middle pipe and the following pipe, the two ends of middle pipe are connected with Seat stay and Chain stay respectively, and Seat stay and Chain stay are connected with hook at the end away from middle pipe.

As of the present utility model a kind of preferred, middle pipe is provided with handle below following pipe.

As of the present utility model a kind of preferred, hook comprises J-shaped gib head, hook body and two hook tails, and the hook tail connects Seat stay and Chain stay respectively.

In sum, the utlity model has following advantage:

1, the utility model is provided with elastomeric element between middle pipe and following pipe, the vibrations of bicycle rear are the pipe place in Chain stay and Seat stay conduct to, the vibrations of front-wheel conduct to down the pipe place, between is provided with elastomeric element so, make vibrations be absorbed with elastic deformation by elastomeric element, effective vibratory sensation that must reduce the people that rides has improved the comfort level of riding.Also rationally be provided with the annexation between each parts of vehicle frame, and separated the existing seat supporting role of original middle pipe,, adopted independent seat support tube again as link, under the identical situation of load-carrying capacity, reduce the use of tubing, reduced cost.
