Bent wood structure in child's bicycle

Abstract

The invention relates to a bent wood structure in a child's bicycle. The bent wood structure comprises a frame part made of a wood material, a metal conversion block part and a middle tube, wherein a bottom bracket of a transmission part of the child's bicycle is fixedly arranged on the bottom of the middle tube during mounting; the frame part is formed by combining two bent plates which are the same in shape; the two bent plates which are the same in shape are clamped into two U-shaped spaces; a hasp for clamping the middle tube is mounted on a juncture of the two U-shaped spaces; the conversion block part and wheels of the child's bicycle are respectively positioned in the two U-shaped spaces; the conversion block part and the frame part are clung and are fixed through a detachable fixing device. The bent wood structure disclosed by the invention replaces a metal tube and a plate structure on a common bicycle. The bent wood structure is adopted, so that consumption of non-renewable resources is effectively reduced; moreover, with the design of the bent wood structure, the whole child's bicycle is relatively light, so that needs of different children at different periods can be met, the resources are saved, and the bent wood processing cost is low.

Description

technical field [0001] The invention relates to a bent wood structure, in particular to a bent wood structure that can be used in a children's bicycle that can be assembled into a slide car used in childhood, and can also be assembled in a bicycle used in childhood. Background technique [0002] At present, the frames of children's bicycles on the market are all made of ferrous metals, non-ferrous metals or carbon fiber composite materials. The above products have the following problems in the manufacturing process and finished products: [0003] 1. The frame part is made of "non-renewable resources"; [0004] 2. Waste water, waste gas, radiation and a large amount of carbon emissions are generated during the processing and manufacturing process, polluting the environment; [0005] 3. From raw materials to finished products, the process is complicated, a lot of equipment is used, and the production process is complicated, resulting in high costs; [0006] 4. The R bending ...
