Description

Technical Field

[0001] The utility model relates to the technical field of bicycles, in particular to a deformable bicycle. Background Art

[0002] A bicycle can be called a bike or a bicycle. It is usually a small land vehicle with two or three wheels. After a person rides on the bicycle, the pedals are used as power. It is a green and environmentally friendly means of transportation. For bicycles used by children (or babies), they are generally two-wheeled with a rear auxiliary wheel structure or a two-wheeled walker. However, no matter what shape or structure of the bicycle or walker, its structure is fixed and the shape cannot be changed, so that it cannot be adapted to children of different ages when using one bicycle.

[0031] As a preferred embodiment, the connecting buckle 24 is rotatably connected to the rear wheel 8 via the first rotating shaft and the first bearing, so that the second adjusting mechanism 7 and the rear wheel 8 are effectively connected, which not only facilitates the second adjusting mechanism 7 to adjust the position of the rear wheel 8, but also ensures that the rear wheel 8 can rotate effectively.

[0032] As a preferred embodiment; the bicycle also includes a seat cushion 35, the seat cushion 35 is connected to a lifting rod 36, and the lifting rod 36 is provided with a plurality of connecting holes 37, the frame 1 is provided with a mounting hole matched with the lifting rod 36 in the vertical direction, and a fastening hole is provided on the side of the frame 1, the seat cushion 35 is inserted into the mounting hole through the lifting rod 36 and the fastening hole and the connecting hole 37 are connected by bolts to form a fixation; the purpose of this structural design is to enable the seat cushion 35 to be adjusted to meet the needs of users of different heights, and the practicality is further enhanced; the process is: first unscrew the bolts there, adjust the lifting rod 36 up and down, and after determining the adjustment height, make the connecting hole 37 correspond to the fastening hole there, and then fasten it by bolts to achieve the height adjustment of the seat cushion 35.

[0033] As a preferred embodiment; the handlebar 2 includes a handlebar 38, a head tube 39 and a front fork 40, the two ends of the head tube 39 are fixedly connected to the handlebar 38 and the front fork 40 respectively, the head tube 39 is rotatably connected to the connecting tube 41 of the frame 1, and the front wheel part 4 includes a foot pedal 42 and a front wheel 43; the front fork 40 is rotatably connected to the front wheel 43 through a second rotating shaft and a second bearing, and the foot pedal 42 is fixedly connected to the second rotating shaft; the setting of the front fork 40 has a certain shock-absorbing effect, and the head tube 39 is rotatably connected to the connecting tube 41 of the frame 1, so that the handlebar 2 can effectively control the direction of the front wheel 43; in addition, the foot pedal 42 can also be used to drive the bicycle to start. When it is a bicycle, it can be convenient for users to pedal the bicycle. When it is a walker, it does not affect children from directly using their legs as power.

[0034] The method of using the utility model is as follows: Figure 1 The figure shows a bicycle. When it is necessary to transform it into a baby walker, first release the limit of the first adjustment mechanism 6 and the second adjustment mechanism 7. The process is: turn the first knob 16 to disengage the first connecting member 11 from the fastening head 18, and then rotate the connecting plate 19. At the same time, turn the second knob 30 to allow the second connecting member 21 to continue to enter the fourth mounting groove inside the bottom connecting head 23, and the second connecting member 21 will also be disengaged from the rotating ring 25, so that the rotating ring 25 can be rotated to adjust the position of the rear wheel 8, and the connecting plate 19 is rotated inwardly for adjustment, and the rear wheel 8 is rotated inwardly for adjustment, so that the two rear wheels 8 are close to each other to form a baby walker.

[0035] It should be pointed out that the main problem in the prior art is that no matter what shape or structure of the bicycle or walker, its structure is fixedly connected and its shape cannot be changed, so that it cannot be adapted to children of different ages when using one bicycle. In the process of growing up, the baby needs to buy a walker first, and then buy a bicycle when he reaches a certain age, which makes the use effect of this type of bicycle poor and difficult to meet the needs of the majority of users;

[0036] Therefore, after the improvement of the present application, by providing a first adjusting mechanism 6 and a second adjusting mechanism 7, after the limit of the first adjusting mechanism 6 is released, the two connecting plates 19 can be rotated inwardly to be deformed. At the same time, after the limit of the second adjusting mechanism 7 is released, the rear wheel 8 is also rotated inwardly, so that the bicycle is transformed into a baby walker, which can be used for two purposes, thereby greatly improving the use effect of the bicycle and better meeting the needs of the majority of users.

[0037] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
