Description

Folding bicycle

The utility model relates to a kind of bicycle, particularly a kind of Folding Bicycle.

Up to now, Collapsible bicycle has many patent application cases, comes into the market but seldom form product, traces it to its cause, and mainly has the deficiency of the following aspects: the one, and intensity difference, dangerous; The 2nd, for old man and women and children, the installation requirement height, office is too many; The 3rd, folding back inconvenience is guided and supported, or is unsuitable for the adult.

The purpose of this utility model is to provide a kind of linking intensity height, and installation is folding easy, can be placed on the bicycle in the bag behind the folding, makes it to be applicable to more the rider of different levels.

The utility model is achieved in that bicycle is made up of handlebar, vehicle frame, wheel, driving device and folding device, the folding device that it is characterized in that its vehicle frame (9) is a kind of touching hook formula unitor (7), and the lifting of described handlebar (1), vehicle seat (3) is finished by spiral lifting structure (2).

Touching hook formula unitor can be bumped groove (20) and is arranged at a left side and bump the securing rod (15) that groove (20) one sides can stretch in the groove that inserts left touching hook (14) automatically and formed by left touching hook (14), the right side of matching with above-mentioned left touching hook (14).

Advantage of the present utility model is: owing to adopt hook-type unitor (7), working strength, safe reliability strengthen greatly, and connect fast; Spiral lockout mechanism makes height adjustment and dismounting easy to be reliable, at a glance can.Handlebar (1) and vehicle seat (3) can take off, and pedal (6) can upwards overturn, the car load easy accessibility, and the time was no more than for 30 seconds.After car load is taken apart, handlebar (1), vehicle seat (3) and folding after integral body, can be placed in the hand baggage, make and carry very conveniently, be widely used in adult and women and children, for the pupil, live the family, building, go on business, go to the countryside, tourism etc. is especially suitable.

Description of drawings: Fig. 1 is the assembly drawing of this car.1 is handlebar, and 2,4 is twist-lock mechanism, and 3 is vehicle seat, and 5 is rear wheel, and 6 pedal for car, and 7 is touching hook formula unitor, and 8 is front vehicle wheel, and 9 is vehicle frame.2, the constructional drawing of 4 twist-lock mechanisms.10 is the person in charge of handlebar (1) among the figure, and 11 is the front fork person in charge of vehicle frame (9), and 12 is lock nut, and 13 is handle.Handlebar is responsible for (10) and upward and in the front fork person in charge (11) is processed with screw thread, makes it and can rotate relatively.In use, the rotation handlebar is responsible for (10) and is made it the height that reaches suitable, and then screws lock nut (12) and get final product.Vehicle seat (3) also adopts this connecting mode with connecting of vehicle frame (9).Fig. 3 is a touching hook formula coupling constructional drawing.(14) are the left touching hook of coupling among the figure, and (20) bump groove for the right side of touching hook formula unitor, and (15) are the securing rod under spring (17) pressure, and (16) for to bump the fixed cover that groove is connected as a single entity with the right side, (18) are the pressure-bearing packing ring, and (19) are the pressure-bearing pin.When left touching hook (14) bumps when securing rod (15), under the effect of inclined-plane power, make on the securing rod and move, pressure-bearing pin (19) on the securing rod drives pad (19) and makes spring (17) compression, when left touching hook (14) when putting in place, securing rod (15) resets under the pressure of spring (17), securing rod (15) is stuck in the groove of touching hook, makes the front and back connection of vehicle frame (9) be straight line.Fig. 4 is the birds-eye view of Fig. 3, and (21) are the turning cylinder of touching hook formula unitor, shown in vehicle frame (9) be the square vehicle frame.In use, push securing rod aside, can make left touching hook (14) serves as that axle is folding with vehicle frame (9) with (21).

When specifically implementing this utility model, can select single-beam formula vehicle frame for use, be beneficial to fold, the radius of front and back wheel should not be too big, to select being advisable of 160MM for use, drives with the people who adapts to all ages and classes level.Vehicle frame is selected square beam for use, can gain in strength.Touching hook formula unitor (7) can be selected the refined steel Quenching Treatment for use, to gain in strength and resistance to abrasion.This touching hook unitor (7) also can be used on the other forms of bicycle of two-beam type.

Claims

1, a kind of Folding Bicycle, formed by handlebar, vehicle frame, wheel, driving device and folding device, it is characterized in that making the folding folding device of vehicle frame (9) is a kind of touching hook formula unitor, and the lifting of described handlebar (1), vehicle seat (3) is finished by spiral lifting structure (2).

2, Folding Bicycle according to claim 1, it is characterized in that: its touching hook formula coupling bumps groove (20) by the right side that left touching hook (14) matches with above-mentioned left touching hook (14), and is arranged at the right side and bumps the securing rod that groove (20) one side automatically retractables insert in the groove of left touching hook (14) and form.
