Embodiment

[0037] As shown in Figure 1-6, two poles of the same shape of the present invention (divided into front pole 10 and rear pole 11) each have a sliding sleeve (front pole sliding sleeve 12, rear pole sliding sleeve tube 13). Two connecting rods (connecting rod I 8, connecting rod II9) of the same shape are superimposed to form an X shape by being positioned at the rotating shaft of its upper third length position, like this, X type connecting rod has two long arms and two For the short arms, the upper ends of the two struts are respectively hinged with the two short arms of the X-shaped connecting rod, and the upper sliding sleeve is respectively hinged with the two long arms of the X-shaped connecting rod for two-thirds of the length. When the two connecting rods of the X type rotate relatively around the common axis, the angle between the two short arms becomes smaller, and the upper ends of the two struts approach, the angle between the two long arms also becomes smaller, and...

Abstract

The invention relates to the field of bicycles, in particular to a folding bicycle, which is characterized in that: the frame of the folding bicycle is a folding frame which is provided with a connecting rod I, a connecting rod II, a front bearing rod, a back bearing rod, a sliding sleeve of the front bearing rod, and a sliding sleeve of the back bearing rod. The connecting rod I and the connecting rod II are intersected and hinged by a pin to form an X-shaped connecting rod; the sliding sleeves are respectively sheathed on the front and the back bearing rods; one end of the connecting rod I is hinged with the front bearing rod, and the other end of the connecting rod I is hinged on the sliding sleeve of the back bearing rod; one end of the connecting rod II is hinged with the back bearing rod, and the other end of the connecting rod II is hinged on the sliding sleeve of the front bearing rod; the front bearing rod and the sliding sleeve of the front bearing rod are hinged with the front part of the automobile body; the back bearing rod and the sliding sleeve of the back bearing rod are hinged with the rear part of the automobile body. The invention can solve the problems of heavier weights and larger size after being folded in the existing folding bicycles, thus having simple operation in folding and convenient carrying.

Description

Technical field [0001] The invention relates to the field of bicycles, in particular to a folding bicycle. Background technique [0002] At present, due to the limited capacity of the bicycle storage, it may be far away from home, there is a cost burden, or there is a certain distance between the boarding station and the departure point or destination, or for reasons such as convenience, people are more and more fond of folding bicycles. The folding bicycle can be freely ridden after being unfolded, and is small in size and light in weight after being folded, and is convenient for storage and carrying. However, most of the folding bicycles produced in China have the disadvantages of heavy weight and large size after folding, and it should be said that they are still relatively bulky. Contents of the invention [0003] In order to make the folding bicycle more convenient to carry, the purpose of the present invention is to provide a folding bicycle, which solves the proble...
