Embodiment Construction
[0020] The present invention will be further described below in conjunction with the drawings.
[0021] Such as figure 1 with 2 As shown, the toggle device for movably coupling between the flywheel and the hub of the folding bicycle of the present invention includes a shift fork structure 4, a screw drive structure 5, a control screw positioning frame 6, a control screw 7 and a knob 8.
[0022] The outer end of the shift fork structure 4 is bent 90 degrees, and a metal block with a threaded hole is welded. The metal block and the control screw 7 cooperate to form the screw transmission structure 5.
[0023] Such as Figure 3-5 As shown, the control screw positioning frame 6 is a 90-degree bent plate, one end of which is compressed and positioned on the rear axle 1 by a sleeve and a nut. The knob 8 is connected with the control screw 7 and fixed on the control screw. On the lever positioning frame 6, the fork of the fork structure 4 is stuck in the fork notch that matches the fork ne...

The invention discloses a movable connection shifting device between a flywheel and a hub of a folding bicycle. The movable connection shifting device comprises a shifting fork structure, a lead screw transmission structure, a control lead screw positioning frame, a control lead screw and a knob. An inner hole of a core structure of the flywheel of the folding bicycle is fittingly in spline joint with the outer edge of a rear axle hub, a fork opening of the shifting fork structure is clamped in a shifting fork notch matched with a shifting fork, and the shifting fork structure and the control lead screw are matched with each other to form the lead screw transmission structure. The movable connection shifting device between the flywheel and the hub of the folding bicycle has the advantages that the movable connection shifting device is simple in structure and low in modification cost, and problems of inflexibility in movement direction and inconvenience in carrying due to the fact that a rear wheel of an existing bicycle only can rotate in a single direction after the existing bicycle is folded can be effectively solved.
Description
Technical field [0001] The invention belongs to the field of portable transformation of folding bicycles, and in particular relates to a movable connection toggle device between a flywheel and a hub of a folding bicycle. Background technique [0002] With the progress of the times and the improvement of social civilization, while the country vigorously promotes energy conservation and emission reduction, people have also begun to advocate the concept of "low carbon, environmental protection, and green travel". More and more people choose to travel by bus or subway, but because the bus and subway line network does not fully cover every corner of the city, there will always be some vacuum areas for green travel, so it can be flexibly folded and easy to carry. While ensuring green travel, bicycles can be well connected with other traffic lines to form a continuous green travel route. With the advancement of technology and the improvement of living standards, people have higher and ...
