Abstract

The utility model relates to an ultra-thin type folding bicycle, which belongs to the field of a vehicle. The problem that the volume of the existing folding bicycle is still larger after folded is solved. The lengths of a front wheel axis 1 and a rear wheel axis 8 of the utility model are both shorter than front and rear wheel axes of other bicycles, wherein, the length of the front wheel axis 1 is 75 mm, and the length of the rear wheel axis 8 is 105 mm. The deflective forward position 24 mm away from the middle position of a frame 9 with a single curved beam is provided with an enclosed type folding joint 4 on which a rotating pin 10 and a switch handwheel 11 are arranged. The utility model has the advantages that the volume of the utility model is thinner and smaller after the utility model is folded, and the utility model is more convenient for people to carry and store.

Description

Super thin type folding bicycle

The utility model belongs to field of vehicles.

Existing folding bicycle, volume after folding is generally all bigger, for example: the product of well-known Taiwan Han Shi company to produce folded bicycle, they are 16 years old " the volume of folding bicycle after folding be 0.711 * 0.457 * 0.266=0.086 (m ³), (" Chinese bicycle " 96 year the 5th phase carries).Afterwards, constantly the someone released new kind, and its volume after folding is more and more littler, and for example the patent No. is 96236535.1, and specification is similarly 16 " Multi-purpose Folding Travelling Cart, the volume after it is folding is 0.635 * 0.465 * 0.23=0.065 (m ³), though little a lot, carry when it goes up train, aircraft, automobile, subway and think that still volume is bigger than normal, that is to say that it is still little convenient sometimes to use.

The purpose of the utility model is to provide a kind of volume after folding thinner, littler folding bicycle.

The utility model comprises front wheel spindle, hind axle, single camber beam vehicle frame, (except the ordinary bicycle part).The length of forward and backward wheel shaft is all shorter than the forward and backward wheel shaft of ordinary bicycle, and wherein front wheel spindle is 75 millimeters, and hind axle is 105 millimeters; Closed folding joint is equipped with at 24 millimeters places, inclined to one side the place ahead, single camber beam vehicle frame middle part, and rotational pin and switch handwheel are housed on the closed folding joint.

Advantage of the present utility model is: volume after folding is thinner littler, for example: 16, and " the specification volume after folding is: 0.64 * 0.46 * 0.16=0.047 (m ³), almost only be above-mentioned taiwan products 1/2,12 " the specification volume after folding is 0.6 * 0.39 * 0.16=0.037 (m ³).Simultaneously, the utility model is in light weight, and folding operation is convenient, thereby conveniently carries and deposit in people.

The contrast accompanying drawing is illustrated below.Fig. 1 is a structural representation of the present utility model, and Fig. 2 is a B-B profile among Fig. 1, and Fig. 3 is full folded state diagram.Among the figure:

1. front wheel spindle 2. quick degree of tightness card 3. handlebars

4. closed folding joint 5. quick degree of tightness card 6. saddles

7. hide axis hole 8. hind axles 9. single camber beam vehicle frames

10. rotational pin 11. switch handwheels

Degree of tightness card 2 is used for controlling handlebar 3 fast.Closed folding joint 4 is contained in the biased anterior position of monotropic beam vehicle frame 9 pars intermedias, the distance of this position and front wheel spindle 1 than with short 24 millimeters of the position of hind axle 8 so that front wheel spindle 1 can be aimed at and hides axis hole 7 when folding.Degree of tightness card 5 usefulness are controlled saddle 6 fast.The utility model is in Fig. 1 state, and then its functions of use and ordinary bicycle are just the same.If need to fold, then carry out in the following order: inhour rotation switch handwheel 11 about totally 6 circles, is seen Fig. 2; The front-wheel untie-sell 10 that rotates is rolled over backward, front wheel spindle 1 is placed hide in the axis hole 7, quick degree of

tightness card

2 and 6 is all unclamped, extract handlebar 3 and saddle 6, they are put between the two-wheeled, see Fig. 3.Because front wheel spindle 1 and hind axle 8 are than common weak point, and front wheel spindle 1 places to be hidden in the axis hole 7, overlapping 20 millimeters with hind axle, be equivalent to shorten 20 millimeters, after so the utility model is folding only 160 millimeters, this numerical value is: the numerical value of front wheel spindle length (75 millimeters)+hind axle length (105 millimeters)-overlapping value (20 millimeters), thereby greatly attenuate the volume behind the bicycle folding.

Claims

A kind of super thin type folding bicycle, mainly form by front wheel spindle (1), hind axle (8), single camber beam vehicle frame (9), closed folding joint (4), rotational pin (10) and switch handwheel (11), it is characterized by: wherein the length of front wheel spindle (1) is 75mm, and the length of hind axle (8) is 105mm; Closed folding joint (4) is equipped with at the 24mm place, the biased the place ahead of pars intermedia of single camber beam (9), and rotational pin (10) and switch handwheel (11) are housed on it.
