Thereby improving the functional diversity of the bicycle.
Description
Technical Field
The invention relates to a bicycle, in particular to a multifunctional bicycle.
Background
Baby carriages are the most typical and common of the baby products, and account for a significant proportion of the overall consumption of the baby product. The baby carriages are various in types, including baby carriages and children bicycles, and each baby carriage has different functions and is suitable for children of different ages. This is a problem, as the existing strollers are single in function, and most households need to purchase multiple strollers for meeting the needs of children in different growth stages. In this way, on one hand, the cost of child care in the home and on the other hand, the replaced baby carriage is usually discarded, and social resource waste is caused. Thus, a more versatile stroller is needed.
Disclosure of Invention
Aiming at the current state of the art, the invention aims to provide the multifunctional bicycle with various functions and reasonable structure.
The technical scheme adopted for solving the technical problems is as follows: a multifunctional bicycle comprises a bicycle frame, wherein a power device which is detachably connected is arranged on the bicycle frame; the power device comprises a housing, a center shaft, a chain wheel, a flywheel and an adapter, wherein the center shaft, the chain wheel, the flywheel and the adapter are arranged in the housing, the chain wheel is connected with the center shaft through a key, the chain wheel is in transmission with the flywheel through a chain, one side of the connector is in threaded connection with the flywheel, at least one connecting rod is arranged on the other side of the connector, and correspondingly, a mounting hole matched with the connecting rod is arranged on a hub of the rear wheel;
the middle part of the frame is provided with a middle shaft mounting seat, the middle shaft mounting seat comprises a first semicircular flange fixed on the frame and a second semicircular flange matched with the first semicircular flange, and the first semicircular flange is abutted with the second semicircular flange.
Furthermore, an end cover is arranged on one side of the middle shaft mounting seat. Prevent the lubricating oil from leaking outside, and prevent external dust from entering the middle shaft mounting seat.
Further, the first semicircular flange is connected with the second semicircular flange through bolts. Is convenient to disassemble and assemble.
Further, the two ends of the middle shaft are respectively connected with pedals.
Compared with the prior art, the invention has the beneficial effects that: by adopting the technical scheme, as the power component is detachable, the power component is not arranged on the frame during the walker learning of children, and the bicycle can be used as a walker; when a child grows at a certain stage and needs to be on a bicycle, the power assembly can be automatically arranged on the bicycle frame, and the bicycle is simple and convenient to operate and stable and reliable in structure. Thereby improving the functional diversity of the bicycle.

Detailed Description
The following description, taken in conjunction with the accompanying drawings, illustrate preferred, but not all, embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1-3, when the multifunctional bicycle is used as a bicycle, the multifunctional bicycle comprises a frame 1 and a power device, wherein the power device comprises a housing 5, a center shaft 4 arranged in the housing, a chain wheel, a flywheel and an adapter, two ends of the center shaft are respectively connected with pedals, the chain wheel is connected with the center shaft through keys, the chain wheel is in transmission 7 with the flywheel through a chain, one side of the connecting piece 8 is provided with threads and 81 is in threaded connection with the flywheel 7, the other side of the connecting piece is provided with at least one connecting rod 82, and correspondingly, a mounting hole matched with the connecting rod is formed in a hub of a rear wheel; the middle part of the frame 1 is provided with a middle shaft mounting seat, the middle shaft mounting seat comprises a first semicircular flange 2 fixed on the frame and a second semicircular flange 3 matched with the first semicircular flange 2, the first semicircular flange 2 is abutted to the second semicircular flange 3, and the first semicircular flange 2 is connected with the second semicircular flange 3 through bolts.
In order to prevent the lubricating oil in the middle shaft from leaking outwards, external dust is prevented from entering the middle shaft mounting seat, and an end cover is arranged on one side of the middle shaft mounting seat.
As shown in fig. 4, the multifunctional bicycle is used as a walker, and a power device is not required to be arranged on a frame of the multifunctional bicycle.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
