Description

Shock-absorbing folding bicycle frame

Technical Field

The utility model relates to the technical field of bicycle, especially, relate to a bicycle frame is folded in shock attenuation.

Background

Bicycles, also known as bicycles or bicycles, are typically two-wheeled small land vehicles. After the person rides the bicycle, the person steps on the pedal as power. Bicycles are a traditional industry, have a history of over a hundred years, and due to the problems of environmental protection and traffic, bicycles become a favorite means of transportation and fitness for residents of all countries in the world, especially developed countries, and the center of gravity of the bicycle industry in the world is being changed from a traditional transportation means instead of walking to sports, mountain land and leisure. The existing bicycle frame is generally of a rigid structure, so that a rider is easy to cause fatigue and has poor comfort due to road jolt in the riding process.

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 shock attenuation folding bicycle frame.

The utility model discloses a realize through following technical scheme:

the utility model provides a folding bicycle frame of shock attenuation, includes girder, rigid coupling in the front fork sleeve pipe of girder front end, rigid coupling in the riser of girder rear end and the back crotch at riser rear, lean on the rear position to be equipped with the scray in the middle of the girder, riser below rigid coupling has the well axle sleeve pipe, lean on lower position rigid coupling to have a supporting seat in the middle of the riser front side, back crotch lower extreme articulates in well axle sleeve pipe rear side, back crotch upper end articulates there is first bumper shock absorber, the first bumper shock absorber other end articulates in the riser rear side, the articulated department downside of articulated of the first bumper shock absorber of back crotch articulates there is the connecting plate, the connecting plate other end articulates in the supporting seat, the connecting plate middle part is equipped with dodges the groove of dodging the riser, the connecting plate is close to that supporting seat position articulates there is the second bumper shock absorber, the second bumper shock absorber other end articulates in girder scray rear side.

The utility model has the advantages that:

in the riding process, vibration caused by road bumping is transmitted to the first shock absorber through the rear fork frame and is transmitted to the second shock absorber through the adjusting plate to filter and absorb the vibration, and when the bicycle is not ridden, the bicycle is folded through the folder. The utility model discloses can fold it when not using the bicycle, reduce its occupation space, two bumper shock absorbers can alleviate the vibration that the road surface jolted and brought by a wide margin, improve and ride passerby's travelling comfort.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. the front fork type folding fork comprises a front fork sleeve, 2. a folder, 3. a stand pipe, 4. a first shock absorber, 5. a rear fork frame, 6. a connecting plate, 7. a middle shaft sleeve, 8. a supporting seat, 9. a second shock absorber and 10. a main beam.

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.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

As shown in the figure, the utility model comprises a main beam 10, a front fork sleeve 1 fixedly connected with the front end of the main beam, a vertical pipe 3 fixedly connected with the rear end of the main beam and a rear fork 5 fixedly connected with the rear end of the vertical pipe, a folder 2 is arranged at the middle rear position of the main beam, the main beam can be folded when not used, the space occupied by the main beam is reduced, a central shaft sleeve 7 is fixedly connected with the lower part of the front side of the vertical pipe, a supporting seat 8 is fixedly connected with the middle lower part of the front side of the vertical pipe, the lower end of the rear fork is hinged with the rear side of the central shaft sleeve, a first shock absorber 4 is hinged at the upper end of the rear fork, the other end of the first shock absorber is hinged at the rear side of the vertical pipe, the vibration caused by road jolt can be reduced, the riding stability and comfort are improved, a connecting plate 6 is hinged at the lower side of the first shock absorber of the rear fork, the other end of the connecting plate is hinged with the supporting seat, an avoiding groove for avoiding the vertical pipe is arranged at the middle part of the connecting plate, the connecting plate is close to the supporting seat and is articulated with second bumper shock absorber 9, the second bumper shock absorber other end articulates in girder scray rear side, further improves the damping effect.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
