Problems solved by technology
[0002] The steering rod and seat rod of the existing folding bicycles are generally folded directly by folding chains, and each fold can only be folded once, and the effect of two folds cannot be obtained for each fold. Although the Chinese patent 200610028415.5 "folding frame" applied for earlier introduced the technology and advantages of the folding frame, its structure uses double ear pieces and groove-shaped parts as other parts for folding, which makes the appearance of the folding frame unsatisfactory

The present invention relates to a folding frame which can be drawn in and spread. It includes upper tube component and lower tube component which are connected by means of folding chain, on the upper tube component a hoop-shaped component is fixed, the top end of its supporting frame is clamped by said hoop-shaped component, the bottom end of said supporting frame is extended into the transverse hole of its folding base seat, the lower tube component is connected with turn-over hinge on the folding base seat by means of welding. Said folding frame can be connected with bicycle front fork tube and handlebar, said folding frame can be formed into the folding frame of bicycle handlebar; if said folding frame is connected with bicycle body and saddle, it can be formed into the folding frame of bicycle saddle tube.
Description
Technical field: [0001] The invention relates to a folding method of a structural part, in particular to a folding frame for a direction bar and a seat bar of a bicycle or a light and small power-assisted bicycle. Background technique: [0002] The steering rod and seat rod of the existing folding bicycles are generally folded directly by folding chains, and each fold can only be folded once, and the effect of two folds cannot be obtained for each fold. Although the Chinese patent 200610028415.5 "folding frame" applied for earlier has introduced the technology and advantages of the folding frame, its structure uses ear pieces and groove parts as other parts for folding, which makes the appearance of the folding frame unsatisfactory. Invention content: [0003] The purpose of the present invention is to provide a folding frame that is beautiful and harmonious, easy to fold, and can obtain two folding effects every time it is folded. The purpose of the present invention is ...
