Embodiment 1

[0036] Such as Figure 1~2 The push pedal non-rotating mechanism used for riding and pushing dual-purpose vehicles, the flywheel 8 is sleeved on the rear wheel shaft 6; a linkage device is also provided, one end of the linkage device is connected to the flywheel 8, and the other end is connected to the seat rod 17. The device can drive the flywheel 8 to axially displace on the rear wheel shaft 6; when the seat rod 17 is lifted, the flywheel 8 is driven by the linkage device to be in the first position in the axial direction of the rear wheel shaft 6, and the flywheel 8 It is connected with the hub of the rear wheel shaft 6; when the seat bar 17 is lowered, the flywheel 8 is in the second axial position of the rear wheel shaft 6, and the flywheel 8 and the rear wheel shaft 6 are separated from the hub connection.

[0037] On a conventional bicycle, the flywheel 8 is connected to the hub of the rear wheel shaft 6, and the flywheel 8 cannot move in the axial direction of the rear...

Embodiment 2

[0039] Such as Figure 1 to Figure 4 As shown, the stroller can be used as a stroller or shopping cart for easy riding or switched to push. When riding, people sit on the seat cushion 18 and ride forward. When promoting, the direction of the handle is turned, and the seat cushion 18 is put down simultaneously, and the rear wheel becomes the front wheel to realize carrying out. At present, the pedal 4 will rotate along with the rotation of the rear wheel 5 due to the presence of the promotion, and the pedal 4 may run into other places or pedestrians, thereby causing inconvenience.

[0040] Under normal circumstances, people step on the pedal 4 to drive the crank 2 to rotate, and the crank 2 drives the sprocket 1, and the sprocket 1 and the flywheel 8 realize the rotation of driving the rear wheel 5 through the chain 3. The present invention has designed a kind of mechanism that prevents the pedal from turning when pushing, has specifically improved the structure of the cushion...

Embodiment 3

[0053] On the basis of the above examples, if Figure 5 The shapes of the teeth on the end faces of the flywheel 8 and the driven wheel 7 are shown. Taking the flywheel 8 as an example, the gear teeth are located on the end surface 52 of the flywheel 8, and the gear teeth are circumferentially distributed on the end surface of the flywheel 8. Two of each gear tooth include two meshing contact surfaces, namely surface one 50 and surface two 51, Wherein the first surface 50 is perpendicular to the end surface 52, and the angle between the second surface 51 and the end surface 52 is an inclined surface, preferably 45°. The same driven wheel 7 end face is provided with the tooth that matches with flywheel tooth. In the process of the flywheel 8 being pushed by the spring one 9 to gradually mesh with the driven wheel 7, because the surface two 51 is an inclined plane, if the two gear teeth are not aligned with each other, then the surface two 51 has a guiding effect, and the surfa...

Abstract

The invention discloses a push pedal non-rotating mechanism for a riding and pushing dual-purpose bicycle. A flying wheel is connected to a rear wheel shaft in a sleeving mode. A linkage device is arranged. One end of the linkage device is connected to the fly wheel and the other end of the linkage device is connected to a cushion bar. The linkage device can drive the fly wheel to move axially onthe rear wheel shaft. When the cushion bar is lifted, the fly wheel is driven by the linkage device to be positioned at a first position in the axial direction of the rear wheel shaft, and the fly wheel is connected with the rear wheel shaft by a propeller boss. When the cushion bar is lowered, the fly wheel is positioned at a second position in the axial direction of the rear wheel shaft, and thefly wheel is no more connected with the rear wheel shaft by the propeller boss. When the riding and pushing dual-purpose bicycle is switched between the pushing mode and the riding mode, the purposeof stopping a pedal to rotate can be achieved by adjusting the height of a cushion. Switching is convenient, no other operation is required, and riding is more convenient after switching.

Description

technical field [0001] The invention relates to a dual-purpose vehicle for riding and pushing, in particular to a non-rotating mechanism for pushing pedals used for a dual-purpose riding and pushing vehicle. Background technique [0002] The patent application No. 201721079031.6 proposes a foldable dual-purpose vehicle for riding and pushing, which can be used for shopping and outdoor activities as a stroller. It can be used for cycling and pushing, and it can be folded. When riding, people step on the pedals to make the vehicle move forward. Changing the direction of the handle can realize pushing. When pushing, the pedals will be driven along with the rotation of the rear wheels. The pedals may bump into other places or cause inconvenience to pedestrians. Contents of the invention [0003] The technical problem to be solved by the invention is to solve the problem that the pedals rotate when the dual-purpose bicycle is pushed. The present invention provides a push ped...
