Problems solved by technology

The disadvantage is that the strength of the frame structure is not good, and it must be reinforced with the help of a reinforcing structure, otherwise it is easy to produce breakage marks from the folding hinges, and its appearance is limited by the folding hinges and folding directions, so it is not easy to design. Consumers accept and love the appearance; in addition, in terms of the volume of packaging materials, although the length of the folding bicycle can be shortened after being folded, its overall width will increase significantly, so it cannot effectively reduce the volume of packaging materials after folding. For manufacturers and dealers, it is still inconvenient whether it is stored or transported; at the same time, the weight of folding bicycles is heavier than that of ordinary stationary bicycles, and its handling is not as good as that of stationary bicycles.

Embodiment Construction

[0026] Please refer to Fig. 1 to Fig. 4 at the same time, the bicycle that is combined by different stress directions provided by the present invention is mainly made up of a front frame 10 and a rear frame 30; wherein the lower tube of the front frame 10 11 is detachably inserted and locked in a combined sleeve 32 welded to the front of the bottom bracket 31 of the rear frame 30, and a first quick-lock clamp 23 is used to lock its joint end; A suspended upper seat tube 19 of the vehicle frame 10 can be stacked above the lower seat tube 36 of the rear frame 30, and inserted into the upper segment sequentially from top to bottom through the seat cushion riser 22 attached to the seat cushion 21 After the seat tube 19 and the lower seat tube 36, use the third and fourth quick-lock clamps 25, 26 to lock the seat tube 22 in the upper and lower seat tubes 19, 36, so as to connect the upper and lower seat tubes 19 , 36, and its connection direction is roughly perpendicular to the dir...

Abstract

A bicycle with the combination of different stress directions for allowing its frame structure to bear push force and pull force has a front frame and a back frame. A lower tube of its front frame is inserted in a sleeve tube of back frame in a detachable mode. The upper segment of saddle tube for front frame and the lower segment of saddle tube for back frame are vertically aligned and the vertical tube of saddle is inserted in them. Finally they are fastened by two locking fixtures.

Description

technical field [0001] The invention relates to a bicycle, in particular to a bicycle combined with different stress directions, which is not only convenient for disassembly and assembly, but also easy to store and transport, and can maintain the structural strength equivalent to the integral frame. Background technique [0002] The traditional frame structure of bicycles can be roughly divided into two categories: fixed type and folding type. [0003] The fixed frame structure is to weld or weld the frame tubes such as the head tube, front fork, upper tube, down tube, seat cushion riser and rear fork into one body in a permanent way. Its advantage is that the structure of the frame is strong and the design of the exterior shape is not limited, and it is easy to design such an appearance shape as a rhombus frame that is easier for consumers to accept and love; and its disadvantage is that the packaging material is too bulky, causing storage problems. The cost of packaging, ...
