Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] See attached figure 1 , The bicycle bracket of the present invention includes: a connecting head and a connecting pipe 60, the connecting head has a connecting sleeve, and one end of the connecting pipe 60 is fixed in the connecting sleeve through a sleeve.

[0023] There are multiple connectors, including a handle connector 10, a seat cushion connector 20, a pedal connector 30, a left wheel connector 40, and a right wheel connector 50. The connectors are connected through a connecting pipe 60 to form a bicycle. The main body of the bracket, wherein the shape of the handle connector 10, the seat cushion connector 20, the pedal connector 30, the left wheel connector 40, the right wheel connector 50 and the connecting pipe 60 is basically consistent with the shape of the existing parts, Therefore, too many explanations are not given in the following description t...

Abstract

The invention relates to the technical field of bicycles, in particular to a bicycle frame and a manufacture method thereof. The frame comprises connecting heads and connecting tubes, wherein each connecting head is provided with a connecting sleeve, and one end of each connecting tube penetrates through and is fixed to the interior of each connecting sleeve. The bicycle frame is provided with the connecting heads with the molded connecting sleeves for directly penetrating through and fixing the connecting ends of the connecting tubes for connecting the adjacent connecting heads so that the connecting heads and the connecting tubes are formed into a whole, thereby effectively improving the anti-deformation capability of the whole bicycle frame, having higher safety, extremely convenient processing and assembly and attractive whole appearance without welding points.

Description

Technical field: [0001] The invention relates to the technical field of bicycles, in particular to a bicycle bracket and a manufacturing method thereof. Background technique: [0002] The materials used for the bicycle frame currently on the market are: carbon steel, chrome-molybdenum steel, stainless steel, aluminum alloy, titanium alloy, carbon fiber material, etc. When producing bicycle brackets, the connecting head and the connecting pipe are generally produced first, and then one end of the connecting pipe is welded to the outer wall of the connecting head by means of electric welding, so that the connecting pipe and the connecting head are fixed together, thereby assembling the bike stand. For the bicycle bracket with the aforementioned structure, due to the large overall volume of the bicycle bracket during welding production, it is very difficult for the operator to perform welding operations, which can easily cause false welding, solder cracking, incomplete weld be...
