Abstract

Structure for moving a folding bicycle (10) has two connecting wheels (20, 30). The two connecting wheels respectively located at the bottom of a telescopic saddle tube (16) and at the bottom of an inner tube (24), which is on a fixed frame of a rear wheel (13). The folded bicycle can slide in virtue of these two connecting wheels (20, 30). One can easily drag the folding bicycle by holding a bicycle saddle (15).

Description

Folding bicycle moving structure

The present invention provides a field of folding bicycle technology, and more particularly to a bicycle moving structure that allows a relatively easy tow movement after the bicycle is folded. Background technique

With the advancement of the times, bicycles have become quite popular when they are not in use. However, bicycles are only short-distance vehicles, and they also require manpower to step on them. Therefore, the mobility is not very strong, but they still have the advantages of environmental protection and energy-free use. Nowadays, there are quite a lot of transportation equipment that can allow folding bicycles to accompany them. Therefore, people will be more willing to use bicycles as a means of transportation.

The above-mentioned known bicycle moving structure still has the following defects:

1. Bicycles have bicycle lanes, but before entering the MRT system or transportation equipment, there is a distance that cannot be ridden. It can only fold the bicycle and move it to the mass transit, but generally after folding. The bicycle still has considerable weight, and the volume is also slightly larger. It is difficult to carry it directly, but it is dragged on the ground, because the folded bicycle wheel has been unfavorable for towing, and the folded bicycle is also unfavorable for hand pulling. This creates another troublesome and thorny issue.

Second, there is no problem in the action of the bicycle before folding, but it can only be carried after folding, and sometimes it is not for carrying. If there is a need to drag, it will cause considerable trouble, and the result will inevitably cause people. The use of folding bicycles is reduced or not used, which is missing. Summary of the invention

It is an object of the present invention to provide a bicycle moving structure to solve the following technical problems: Bicycle riding has a bicycle lane, but before entering the MRT system or transportation equipment, there is a distance that cannot be ridden. The bicycle can only be folded and moved to the mass transit vehicle, but the folded bicycle is still quite heavy, and the volume is also slightly larger. It is difficult to carry it directly, but it is dragged on the ground because it is folded. The rear bicycle wheel has been unfavorable for towing, and the folded bicycle is also disadvantageous for hand gripping, thus creating another troublesome and troublesome problem.

Technical features of the problem: A bicycle moving structure, mainly provided with two pulley seats at the bottom of the telescopic seat tube of the bicycle and the bottom of the rear wheel. According to this, when the bicycle is folded, the two pulleys can be folded The bottom side of the bicycle, and can slide smoothly, and the bicycle seat cushion can be used for holding and towing, so that it is quite convenient to drag the folding bicycle with one hand, so that Easily moved to transportation equipment and free of handling.

Compared with the efficacy of the prior art: the prior art can only fold the bicycle, and then can only carry it, and often does not need to carry, but uses towing, but the folding bicycle can not be used, and the present invention is folded The rear side of the bicycle is provided with two pulleys. Thus, the seat cushion can be provided for one-handed holding, and the two pulleys can be used to drag the folded bicycle, which is quite convenient to use. DRAWINGS

Referring to FIG. 1, a schematic plan view of a bicycle moving structure according to an embodiment of the present invention includes:

A folding bicycle 1 0, the folding bicycle 10 has a riser 1 1 , a rear fork 1 2, 2 wheels 1 3, a crank 1 4 and a mat 1 5 and a tube 1 6;

a first coupling wheel 20 (shown in FIG. 4), the first coupling wheel 20 has a sleeve portion 21 and a bottom end of the sleeve portion 2 1 forms a U-shaped seat 2 2 , the U-shaped seat 2 2, a pulley 2 3 can be pivoted, the sleeve portion 2 1 of the first coupling wheel 20 can be sleeved on the inner tube 24 of the fixed structure, and the outer tube 121 and the rear fork 12 are fixedly integrated, and the outer tube 12 1 The inner tube 24 is sleeved and stretched, and is fixed after the expansion and contraction is completed. The sleeve portion 2 1 of the first joint wheel 20 forms an elastic slot 2 1 1 and an elastic slot 2 1 1 on both sides. Two ears 2 2 2, 2 1 3, two ears 2 1 2, 2 1 3 when locked with screws 214, the sleeve portion 2 1 can be tightly sleeved and fixed to the bottom of the inner tube 24;

a second coupling wheel 30 (shown in FIG. 3), the second coupling wheel 30 has a sleeve portion 31 and a side portion of the sleeve portion 3 1 is provided with a convex portion 3 2 , and the convex portion 3 2 A U-shaped seat 3 3 extends in a vertical direction, the U-shaped seat 3 3 is pivotally provided with a pulley 3 4 , and the sleeve portion 31 of the second coupling wheel 30 is sleeved on the bottom of the seat tube 16 6 and the sleeve portion 3 1 and form an elastic slot 3 1 1 and two slots 3 1 2, 3 1 3 on both sides of the elastic slot 3 1 1 , when the two ears are locked by screws 3 1 4, the sleeve portion 3 can be made 1 tightly sleeved and fixed on the bottom of the bicycle seat tube 16;

Referring to FIG. 2, it is a plan view of another embodiment of the present invention, wherein the outer tube 1 2 1 can also be fixed on a support plate 25, and the middle portion of the support plate 25 is screwed to the folding bicycle 10. The free end of the support plate 25 is inserted into the slit of the rear fork to form a two-point support and is more stable. The inner tube 2 4 and the first combined wheel 20 are supported.

Through the above combination, the first combining wheel 20 (shown in FIG. 1) and the second combining wheel 30 can be retracted without being hindered until the two wheels 1 3 are normal when the folding bicycle 10 is deployed as a bicycle. Rotate the ground, and when the folding bicycle 1 Q is folded, the first combined wheel 20 and the second combined wheel 30 can be pulled out and fixed, and the pulleys 2 3, 3 4 (Fig. 3, Fig. 3) 4) Snap on the ground, and hold the seat cushion 1 5 position (as shown in Figure 5), you can easily drag the folding bicycle 10, which is easy to move after the bicycle is folded.
