Abstract

The invention relates to a folded wheel type bicycle which comprises a frame and wheels, wherein the frame comprises a front vertical pipe and a back vertical pipe; and each wheel comprises a rim, spokes and a middle axle. The folded wheel type bicycle is characterized in that the rim is a ring formed by sequentially hinging multiple sections of loops; one end of each spoke is fixedly provided with a sliding block, and the inner circumferential surface of the rim is provided with a circle of sliding chute matched with the sliding block of each spoke; and the other end of each spoke is sleeved on the middle axle, and a compression nut forms threaded connection on the middle axle at the outer side of each spoke. Since the wheels can be folded, the diameter of the wheels does not need to be deliberately reduced in order to reduce the volume of the folded bicycle, thereby ensuring that the ride is more comfortable, convenient and labor-saving.

Description

The folding wheel bicycle

Technical field

The present invention relates to technical field of bicycles, specifically is a kind of folding wheel bicycle.

Background technology

Bicycle since coming out, has enjoyed people to favor as the energy-conservation vehicle of a kind of important low-carbon environment-friendly always.Along with the quickening of life paces, the increasing gradually of the serious day by day and operation pressure of traffic congestion phenomenon, people's exercise time is also fewer and feweri; The green health idea becomes more and more popular; Therefore, People more and more hopes to have a kind of more convenient, more environmental protection trip mode, at this moment; Bicycle rely on self environmental protection, convenient convenience, take exercises and can not block up, dangerous advantage such as little, become the preferred traffic instrument of people's trip.

Folding bicycle rely on self volume after folding little, deposit, advantage such as convenient in carrying, have more preceence.Though in the prior art, folding bicycle structure, folding mode are varied, general wheel is all very little, and the effort of riding, and foldable structure is reasonable inadequately is compact inadequately, causes folding back bicycle volume bigger, causes to carry that to carry still be not very convenient.And existing folding bicycle generally adopts inflatable inner tube, needs often inflation, and often pricked, and is prone to the tire that exposes to the sun summer, and service life is short.

Summary of the invention

In order to overcome the shortcoming that above-mentioned prior art exists, the object of the present invention is to provide a kind of folding wheel bicycle, its wheel can fold, and therefore needn't painstakingly dwindle wheel diameter for reducing volume after folding, guarantees the traveling comfort of riding.

In order to address the above problem, the present invention adopts following technical scheme: this folding wheel bicycle comprises vehicle frame, wheel; Said vehicle frame comprises preceding standpipe, rear profile tube; Said wheel comprises wheel rim, spoke, axis; Said wheel rim is hinged to annular in order by multistage arc circle body; One end of said spoke is installed with slide block, and the inner peripheral surface of said wheel rim is provided with the chute that a circle matches with the slide block of spoke; The other end of said spoke is nested with on the axis and be positioned at the spoke outside hold-down nut that on axis, has been threaded.

As further technical scheme of the present invention:

In this folding wheel bicycle, said before the rear side of the standpipe vertical shaft before that is connected; The front side of said rear profile tube be connected one the back vertical shaft; The front end of one intermediate pipe is relatively turnable to be nested with on preceding vertical shaft, and the rear end is relatively turnable to be nested with on the vertical shaft of back.

The invention has the beneficial effects as follows: its wheel can fold, therefore needn't be for reducing volume after folding, and painstakingly dwindle wheel diameter, it is more comfortable convenient and strength-saving to ride; In addition, vehicle body is folding also very convenient.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is done further explanation:

Fig. 1 is the structural representation of wheel in the embodiment of the invention;

Fig. 2 is the mounting structure scheme drawing of spoke and axis in the embodiment of the invention;

Fig. 6 is the structural representation of vehicle frame folding state in the embodiment of the invention;

Among the figure: 1 wheel rim, 2 spokes, 3 axis, 4 hinges, 5 slide blocks, 6 chutes, 7 hold-down nutes, 8 preceding standpipes, 9 rear profile tubes, 10 preceding vertical shafts, 11 back vertical shafts, 12 intermediate pipes.

The specific embodiment

This folding wheel bicycle comprises vehicle frame, wheel.

As shown in Figure 1, said wheel comprises wheel rim 1, spoke 2, axis 3; Said wheel rim 1 is hinged to annular through hinge 4 in order by multistage arc circle body; One end of said spoke 2 is installed with slide block 5, and the inner peripheral surface of said wheel rim 1 is provided with the chute 6 that a circle matches with the slide block 5 of spoke; The other end of said spoke 2 is nested with on the axis 3 and be positioned at spoke 2 outsides hold-down nut 7 that on axis 3, has been threaded, and is as shown in Figure 2.

During the wheel non-folded state, the end of the spoke 2 on 7 pairs of axis that are nested with 3 of hold-down nut compresses, and realizes fixing spoke 2.When wheel folds, rotate hold-down nut 7, remove compressing spoke 2 ends; Spoke 2 can rotate around axis 3, and as shown in Figure 3, the slide block 5 that is installed in spoke 2 other ends slides in the chute 6 of wheel rim 1; The slide block 5 of all spokes 2 after all sliding in the chute of one section arc circle body is opened the hinge between wantonly two sections arc circle bodies, can each section arc circle body be folded up successively; As shown in Figure 4, promptly realized the folding of wheel.

As shown in Figure 5, said vehicle frame comprises preceding standpipe 8, rear profile tube 9; The rear side of standpipe 8 vertical shaft 10 before that is connected before said; The front side of said rear profile tube 9 be connected one the back vertical shaft 11; The front end of one intermediate pipe 12 is relatively turnable to be nested with on preceding vertical shaft 10, and the rear end is relatively turnable to be nested with on the vertical shaft 11 of back.

When vehicle body folded, intermediate pipe 12 front ends rotated around preceding vertical shaft 10, and vertical shaft 11 rotates around the back in the rear end, can vehicle body be folded into the N type, and is as shown in Figure 6.
