Abstract

The utility model discloses a multifunctional folding bicycle. Two front wheels which are parallel are arranged on both ends of a front wheel shaft, a transverse frame is divided into a front section and a rear section, and a steering column jacket, a front transverse frame, a rear transverse frame and a saddle main frame which are arranged at the center of the front wheel shaft are orderly connected through a folding, steering and connecting mechanism. A big chain disk is arranged on the rear transverse frame through a chain disk frame and is fixed by a clamp tenon, the upper end of the saddle main frame and a small chain disk are connected through a rear support frame, and both ends of the rear support frame are connected with moveable hinge heads. The folding bicycle has the advantages of small volume and light weight. People can ride the folding bicycle for replacing walking when the folding bicycle is unfolded. The folding bicycle can be used as a handcart to load goods and people when the folding bicycle is folded. The folding bicycle is especially suitable for people to go to work and off work and is suitable to be used in journey.

Description

The multifunction folding bicycle

The utility model relates to a kind of bicycle, especially has the Folding Bicycle of multiple functions such as bicycle, hand barrow.

The continuous expansion of city scope at present, many people's workings or outdoor activity all will be taken subway or other public transport means, and from shelter to the distance that often has a section to grow the bus station field, be necessary to seek a kind of " relaying " vehicle, certain speed should be arranged, again volume little, in light weight, be convenient for carrying.And existing Folding Bicycle exists that volume is big, function singleness, carry shortcoming such as inconvenience.

The purpose of this utility model is exactly the multifunction folding bicycle that can use as hand barrow provide a kind of volume little, in light weight, simple in structure, folding in order to overcome above-mentioned weak point after.

The purpose of this utility model is achieved by the following technical solution: this multifunction folding bicycle, comprise wheel, handle, big or small chain drum, vehicle seat support, step tread plate etc., and there are two front-wheels that are parallel to each other at the two ends of front wheel spindle; Crossbearer divides forward and backward two sections, is connected by the bindiny mechanism that turns back, between the front end of preceding crossbearer and the steering column jacket that is installed in the front wheel spindle center, afterwards also be connected by the bindiny mechanism that turns back between rear end and the vehicle seat body frame lower end of crossbearer; Big chain plate is placed on the crossbearer back segment by chain drum, is fixed by trip; Be connected by the two ends after poppet that moves twist joint of taking over a job between vehicle seat body frame upper end and little chain drum.

Adopt such structure, as long as crossbearer is turned back from the centre, big chain plate is up mentioned when not riding, trailing wheel is drawn close forward, promptly can be folded into light buggy; Body tail after folding rotated to revolve to axle sleeve to be turn 90 degrees, and whole car volume that then becomes is littler, is easy to carry, and can place car, ship seat down or in the baggage container.So this multifunction folding bicycle structure is simple, folding convenient, volume is little, and is in light weight, opens rideable riding instead of walk, it is folding that can to do the hand barrow loading manned, be well suited on and off duty and the travelling way in use.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the structural representation of Folding Bicycle of the present utility model when opening.

Fig. 2 is the structural representation of this Folding Bicycle when being folded into hand barrow.

Fig. 3 is the structural representation of this Folding Bicycle when carrying and depositing.

Fig. 4 is the turn back enlarged diagram of bindiny mechanism 8 of Fig. 1.

Fig. 5 is that turn back another of bindiny mechanism 8 implemented the enlarged diagram of structure.

As Fig. 1, there are two front-wheels that are parallel to each other 4 at the two ends of front wheel spindle 20; Crossbearer divides forward and backward two sections, is connected by the bindiny mechanism 8 of turning back, between the front end of preceding crossbearer 5 and the steering column jacket 19 that is installed in the front wheel spindle center, afterwards also be connected by the bindiny mechanism 8 that turns back between rear end and vehicle seat body frame 16 lower ends of crossbearer 6; Big chain plate 18 places on the crossbearer 6 of back by chain plate rail 9, and is fixing by trip 17; 10 on the upper end of vehicle seat body frame 16 and chainlet dish are connected by the take over a job after poppet 12 of moving twist joint 13 of two ends.Height according to the user is promptly rideable by the height that stop spanner 14 regulates handle 1, vehicle seat 15.

When needs are used as hand barrow, at first vehicle seat 15 is advanced in the vehicle seat body frame 16, by 14 lockings of stop spanner, then front and back

crossbearer

5,6, between preceding crossbearer 5 steering column jackets 19, the location of three bindiny mechanisms 8 that turn back pin 22 alive is extracted between back crossbearer 6 and the vehicle seat body frame 16, open trip 17 simultaneously, big chain plate 18 is up mentioned, crossbearer is mentioned from the centre, front and back

crossbearer

5,6 promptly to folding up, trailing wheel is close to forward thereupon, with the bolt taut band on the Handle cover 2 24 vehicle body after folding is fastened again, be the buggy of forming by two front-wheels, one trailing wheel, as Fig. 2.But loading or take Xiao Tong on the baggage rack 3.

When needs carry or deposit bicycle, handle 1 is advanced in the Handle cover 2, by 14 lockings of stop spanner, the body tail of folding up, promptly comprise parts such as trailing wheel 11, big or

small chain drum

18,10, vehicle seat body frame 16, front and

back crossbearer

5,6, steering column jacket 19 rotation an angle of 90 degrees around the center that is positioned at front wheel spindle 20, turn over 90 degree on the baggage rack 3, whole car is folding fully, and the volume that becomes is littler, be more convenient for carrying and depositing, as Fig. 3.

Turn back bindiny mechanism 8 except living pin 22 forms by as shown in Figure 4 turning cylinder 21 and location in the foregoing description, also can adopt mode as shown in Figure 5, promptly form with being fixed in by the projection on a connection piece 23 by turning cylinder 21,23 position-limiting actions of projection only allow to turn back to a direction.

In order to alleviate the weight of car as far as possible, the parts of Folding Bicycle of the present utility model adopt the light material manufacturing as crossbearer, handle, vehicle seat body frame, chain plate rail, after poppet etc., as aluminum alloy, carbon fiber.Step tread plate 7 can be selected existing folding pedal plate for use.
