Abstract

The utility model relates to a bicycle rack technical field especially relates to a two shock attenuation bicycle frames, including front fork sleeve, saddle sleeve pipe, well axle sleeve pipe and rear axle yoke, saddle sleeve pipe below sets up upright roof beam set up the type of bending crossbeam between front fork sleeve pipe and the last upright roof beam, the type of bending crossbeam includes first crossbeam and second crossbeam set up the sloping between well axle sleeve pipe and the second crossbeam, rear axle yoke includes rear axle upper boom and rear axle lower beam, the front end and the lower vertical beam fixed connection of rear axle upper boom and rear axle lower beam, rear axle yoke tail end sets up rear axle tail hook, at the articulated first damping spring of sloping upper end and rear axle upper boom front end rear axle upper boom with the articulated second damping spring of upper boom lower extreme. Under the cushioning effect of first damping spring and second damping spring, the buffering comes from the impact force on ground, improves the comfort level and the security of the process of riding.

Description

Double-damping bicycle frame

Technical Field

The utility model relates to a bicycle frame technical field especially relates to a two shock attenuation bicycle frames.

Background

In order to relieve air pollution and urban traffic pressure, the bicycle is more and more adopted as a green healthy travel mode, has the advantages of environmental protection, convenience and the like, and can play a body-building role while riding instead of walking.

In the prior art, the bicycle frame does not have a damping function or the damping function is weak, so that when a riding bicycle passes through a road section with a poor road surface condition, large jolts are easily generated, and the riding comfort level and safety are affected.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a two shock attenuation bicycle frame.

The utility model discloses a realize through following technical scheme:

the utility model provides a two shock attenuation bicycle frame, includes front fork sleeve, saddle sleeve pipe, well axle sleeve pipe and rear axle fork frame, its characterized in that: an upper vertical beam is arranged below the saddle sleeve, a lower vertical beam is arranged between the upper vertical beam and the middle shaft sleeve, a containing area is arranged between the upper vertical beam and the lower vertical beam, a bending type cross beam is arranged between the front fork sleeve and the upper vertical beam, the bending type cross beam comprises a first cross beam fixedly connected with the front fork sleeve and a second cross beam fixedly connected with the lower end of the upper vertical beam, the first cross beam and the second cross beam are connected at the bending position through a folder, an oblique beam is arranged between the middle shaft sleeve and the second cross beam, the upper end of the oblique beam is welded with the second cross beam, the lower end of the oblique beam is hinged with the lower vertical beam through a hinge shaft, the rear shaft fork frame comprises a rear shaft upper rod and a rear shaft lower rod, the front ends of the rear shaft upper rod and the rear shaft lower rod are fixedly connected with the lower vertical beam, and the rear ends of the rear shaft upper rod and the rear shaft lower rod are hinged through a hinge shaft, the rear shaft fork frame is characterized in that a rear shaft tail hook is arranged at the tail end of the rear shaft fork frame, the upper end of the oblique beam and the front end of the upper rod of the rear shaft are hinged with a first damping spring in the containing area, and the upper rod of the rear shaft and the lower end of the upper vertical beam are hinged with a second damping spring.

The utility model has the advantages that:

because the setting is in the first damping spring of sloping upper end and rear axle upper boom front end with set up the rear axle upper boom with the second damping spring of last upright roof beam lower extreme when riding the highway section of jolting, by the cooperation relation compression between rear axle upper boom and rear axle lower beam and the lower upright roof beam first damping spring, go up the cooperation relation compression between upright roof beam and the second crossbeam the second damping spring can cushion to the impact that comes from the road surface effectively, improves the comfort level and the security of the process of riding.

Drawings

Fig. 1 is a schematic view of the structure of the present invention.

In the figure: 1. the front fork comprises a front fork sleeve, 2 a saddle beam sleeve, 3 an upper vertical beam, 4 a first cross beam, 5 a second cross beam, 6 an oblique beam, 7 a rear shaft upper rod, 8 a middle shaft sleeve, 9 a first damping spring, 10 a second damping spring, 11 a rear shaft tail hook, 12 a folder, 13 a lower vertical beam and 14 a rear shaft lower rod.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, two shock attenuation bicycle frame, including front fork sleeve 1, saddle sleeve pipe 2, well axle sleeve pipe 8 and rear axle crotch, its characterized in that: an upper vertical beam 3 is arranged below the saddle sleeve 2, a lower vertical beam 13 is arranged between the upper vertical beam 3 and a middle shaft sleeve 8, a holding area is arranged between the upper vertical beam 3 and the lower vertical beam 13, a bending type cross beam is arranged between the front fork sleeve 1 and the upper vertical beam 3, the bending type cross beam comprises a first cross beam 4 fixedly connected with the front fork sleeve 1 and a second cross beam 5 fixedly connected with the lower end of the upper vertical beam 3, the first cross beam 4 and the second cross beam 5 are connected at the bending position through a folder 12, an oblique beam 6 is arranged between the middle shaft sleeve 8 and the second cross beam 5, the upper end of the oblique beam 6 is welded with the second cross beam 5, the lower end of the oblique beam 6 is hinged with the lower vertical beam 13 through a hinge shaft, the rear shaft fork frame comprises a rear shaft upper rod 7 and a rear shaft lower rod 14, and the front ends of the rear shaft upper rod 7 and the rear shaft lower rod 14 are fixedly connected with the lower vertical beam 13, the rear axle upper rod 7 is hinged to the rear end of the rear axle lower rod 14 through a hinge shaft, the rear axle fork frame tail end is provided with a rear axle tail hook 11, the upper end of the oblique beam 6 and the front end of the rear axle upper rod 7 are hinged to a first damping spring 9 in the containing area, and the rear axle upper rod 7 and the lower end of the upper vertical beam 3 are hinged to a second damping spring 10.
