The angle between the supporting arm and the frame can be adjusted by rotating the adjusting rod so as to adapt to wheels of different types, reduce the pressure of tires and rolling shafts, adjust resistance and avoid riding difficulty.

Drawings

The invention will be further explained with reference to the drawings and examples, wherein:

FIG. 1 is a schematic structural view of the adjustable supporting device for outdoor exercise of a bicycle in a narrow space;

fig. 2 is a cross-sectional view of the inventive device;

fig. 3 is a schematic view of the utility model of the adjustable supporting device for realizing the outdoor exercise function of the bicycle in a narrow space.

Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in figures 1-3, the device for realizing the function of outdoor exercise of the bicycle in a narrow space comprises a frame 2, a supporting arm 1, a mandril 4, a transmission structure and an inertia flywheel.

One end of the supporting arm 1 is hinged on the frame 2, the other end of the supporting arm 1 is provided with two opposite push rods 4, and a rear wheel axle of the bicycle is fixed on the supporting arm 1 through the push rods 4. The transmission structure comprises a roller 5, a reduction gearbox and a driving wheel 7, wherein the roller 5 is in contact with a bicycle wheel and transmits torque, the roller 5 is connected with the reduction gearbox, the reduction gearbox is connected with the driving wheel 7, the driving wheel 7 is installed on the rack 2, and the inertia flywheel is fixed at one end of the roller 5.

The utility model discloses the device is when using, at first is connected with the rear axle of ordinary bicycle, and the rear wheel and the roller bearing 5 contact of bicycle, when riding, exert the effort to the pedal, drive roller bearing 5 and rotate when the rear wheel rotates, drive wheel 7 through reducing gear box and belt drive's mode and rotate, and the speed of normally riding reduces substantially through the reducing gear box to realize that the bicycle moves ahead at a slow speed and removes. The reduction ratio of the reduction gearbox is more than 700 times, and the normal riding speed can be greatly reduced, so that the aim of only riding for one circle at home after half an hour of movement is achieved. The inertia flywheel is arranged to enable the bicycle to run from the inertia in normal running and ensure the smooth running and the smooth running.

The bicycle advances the in-process, because self has certain kinetic energy, this kinetic energy can keep the stability and the smooth and easy degree of riding, even at the in-process of riding, the power on the pedal reduces to some extent, and the motion state of bicycle can not change suddenly yet, but change and steadily change according to the dynamics on the pedal. By utilizing the point, the utility model discloses increase an inertia flywheel on the roller bearing. Kinetic energy generated by high-speed rotation of the inertia flywheel is equivalent to riding kinetic energy, and the effect of simulating riding is achieved.

Further, still be equipped with between frame 2 and the support arm 1 and adjust pole 3, be equipped with first support on the support arm 1, be equipped with the second support in the frame 2, be equipped with the screw hole axle 6 of taking the screw hole on the first support, be equipped with the blind hole axle 9 of taking the blind hole on the second support, be equipped with the external screw thread on adjusting pole 3, adjust the one end of pole 3 and pass the screw hole of screw hole axle 6 and insert in the blind hole of blind hole axle 9. Through the angle between the adjustable support arm 1 of rotation regulation pole 3 and frame 2 to the wheel of adaptation different grade type reduces tire and roller bearing 5's pressure, adjusts the resistance, avoids riding the difficulty.

Further, be equipped with auxiliary wheel 8 on the frame 2, auxiliary wheel 8 width is 180~220mm, and preferred 200mm both can prevent that the bicycle from empting, make the bicycle have certain space of swaying again, more is close the actual scene of riding.

While the embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and many modifications may be made by one skilled in the art without departing from the spirit and scope of the present invention as defined in the appended claims.
