Abstract
The utility model discloses an integrated bicycle frame. The integrated bicycle frame comprises a front fork pipe, a vertical pipe and a bicycle body cross beam, wherein the bicycle body cross beam is arranged between the front fork pipe and the vertical pipe. A center shaft pipe is arranged at the lower end of the vertical pipe. The vertical pipe is provided with a vertical fork, and the vertical fork is provided with a stiffening rib. A rear fork is arranged between the center shaft pipe and the vertical fork. The cross section of the bicycle body cross beam is U-shaped, the upper surface of the bicycle body cross beam is a straight beam, the lower surface of the bicycle body cross beam is a curved beam, and the curved beam extends and is connected with the center shaft pipe. Due to the fact that the curved beam on the lower surface of the bicycle body cross beam extends and is connected with the center shaft pipe, bearing capacity of the whole bicycle frame is improved. Due to the fact that the stiffening rib is arranged on the vertical fork, strength of the rear fork is improved.
Description
Technical field
The utility model relates to a kind of bicycle rack, especially a kind of integral bike frame.
Background technology
Traditional bicycle rack is by various tube stampings, welding fabrication then, and such processing mode structure more complicated, and also cost is than higher.Because the cause of welding also may cause in a collection of vehicle frame because the reason of operation construction causes the generation of substandard products respectively.And the problem that the bicycle rack of traditional casting mold integral body exists bulk strength to descend.
Summary of the invention
Goal of the invention: at the deficiencies in the prior art, the applicant through experimental design repeatedly a kind of integral bike frame.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the utility model adopts is: a kind of integral bike frame, comprise front fork tube, standpipe and be arranged at car body crossbeam between described front fork tube and the standpipe, described standpipe lower end is provided with central siphon, be provided with upright fork on the described standpipe, described upright sticking is provided with ribbed stiffener one.
Be provided with the back chain stay between described central siphon and the upright fork.
The cross-sectional plane of described car body crossbeam is U-shaped, and the upper surface of described car body crossbeam is straight beam, and lower surface is curved beam, and described curved beam extension is connected with central siphon.
Beneficial effect: the utility model compared with prior art, its beneficial effect is:
1, the car body crossbeam lower surface curved beam extension of this device employing is connected with central siphon, increases the weight capacity of unitized frame;
2, this device has added ribbed stiffener one upright sticking, and has increased the intensity of back vent;
3, this apparatus structure is simple, cost is lower, makes more convenient.
Description of drawings
Fig. 1 is the structural representation of a kind of integral bike frame of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, by a most preferred embodiment, technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of integral bike frame comprises front fork tube 1, standpipe 3 and is arranged at car body crossbeam 2 between described front fork tube 1 and the standpipe 3 that described standpipe 3 lower ends are provided with central siphon 6, be provided with upright fork 4 on the described standpipe 3, be provided with ribbed stiffener 5 on the described upright fork 4.
Be provided with back chain stay 7 between described central siphon 6 and the upright fork.
The cross-sectional plane of described car body crossbeam 2 is U-shaped, and the upper surface of described car body crossbeam 2 is straight beam, and lower surface is curved beam, and described curved beam extension is connected with central siphon 6.Like this when making, car body crossbeam 2 and central siphon 6 just can realize that the parts of integral type make.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
