Description

Multi-functional combination does not have the chain cart

The utility model relates to a kind of multi-functional combination does not have the chain cart, belongs to the technical field of bicycle.

Wheelbarrow and bicycle all are a kind of apparatuses of sport and body-building, bicycle can also be used as the vehicle, solely car moves and progressively develops into a kind of motion of riding of novelty at present, capability of reaction in fitness that can both improve the cyclist aspect total balance of the body and the acrobatics and tumblings and maintenance balance, but wheelbarrow also has some shortcomings, make it can not penetration and promotion, for example wheelbarrow has only a wheel, the skill of car of walking alone of will on top of riding, still have certain difficulty, and safety is relatively poor, wheelbarrow can't be used as the vehicle in addition, existing wheelbarrow function singleness can not be used by the double as bicycle.If purchase bicycle and wheelbarrow simultaneously, just change Fei Taigui.

Chinese patent CN1099345A (93116520.2) folding lever bicycle, its transmission adopt foot-operated by being that the crank conduction chain of fulcrum drives flywheel with the rear axle, and two final drive gears link to each other through pulley by belt, parts are more in addition for this bicycle, maintenance is inconvenience very, and car load is heavier, has the mechanical drive loss, and greasy dirt is arranged, in the process of riding, often be prone to chain rupture and fall the chain phenomenon, as for chain-less bicycle, though its driving efficiency is high, also do not have greasy dirt, but cost is higher.

The purpose of this utility model is that a kind of multi-functional combination chain-less bicycle will be provided, and it can overcome above-mentioned shortcoming, and it both can use as wheelbarrow, can be used as cart and hand barrow again, and simple in structure, be easy to make, weight is also lighter, volume is little, and sturdy and durable, keeps in repair easy.

The purpose of this utility model is achieved in that

A kind of multi-functional combination does not have the chain cart; by front fork; back vent; front-wheel; trailing wheel; saddle is formed; each connects preceding pipe box (4) and rear casing (5) to it is characterized in that adaptor union (1) two ends; rear casing (5) has lock hole (6) and the last lock hole of saddle standpipe (19) to be connected; fixing with mortise lock or special-purpose lock; preceding pipe box (4) connects a front fork (14); front-wheel (15) is equipped with in its lower end; front fork (14) upper end affixed leader's standpipe (12) and handle (13); be provided with in the middle of the adaptor union (1) and rotate node A; B (3) and safety guard-safeguard pipe box (2); decoupling rod (8) one ends are fixed on protection steamboat (10) axle; the other end is installed on the back vent (7) with movable whorl; strut bar (9) one ends are fixed on protection steamboat (10) axle, and the other end is fixed in the bearing below of trailing wheel (18) axle.

Click's grip (16) is housed on the handle (13).

The multi-functional combination of Fig. 1 does not have chain cart scheme drawing.

Now the structure of in conjunction with the accompanying drawings multi-functional combination not being had a chain cart is described in detail:

By Fig. 1, pipe box (4) and rear casing (5) before adaptor union (1) two ends respectively connect one, rear casing (5) has lock hole (6), link with the lock hole on saddle pipe and the saddle standpipe, the saddle standpipe has 5-2 lock hole, can be used to adjust the height of saddle, with latch or special-purpose fixedly a connector (1) saddle standpipe (19) and the pipe locked, the preceding pipe box (4) of adaptor union (1) connects a front fork (14), a front-wheel (15) is equipped with in the front fork lower end, front fork (14) upper end affixed proficiency handle riser (12) and handle (13), the handgrip standpipe can turn to 90 degree, so that the volume of the cart after folding reaches minimum degree.

Be provided with in the middle of the adaptor union (1) and rotate node A, B (3); and safety guard-safeguard pipe box (2); (20 move back on one side the safety guard-safeguard pipe box when folding; rotate node A, B (3), press equidirectional and rotate, front-wheel (15) and trailing wheel (18) just can fold symmetrically like this; foot-operated by the space between the spoke; so the cart after folding can reach the volume minimum, can be used as hand barrow and use, be used for delivering luggage.

As launch this cart; the safety guard-safeguard pipe box entangled rotates node A, B (3), make and rotate node and no longer can rotate, between safety guard-safeguard pipe box (2) two ends and the adaptor union (1) with concavo-convex groove or use spiral method of attachment; after like this condom being fixed, just can be used as bicycle and use.

Trailing wheel (18) is equipped with in back vent (7) lower end; decoupling rod has single or double acting door on (8); one end is fixed on the axle of protection steamboat (10); decoupling rod (8) other end is installed on the back vent (7) with the movable screw folder; can adjust protection steamboat (10) and ground distance, strut bar (9) one ends are fixed on the axle of protection steamboat (10), and the other end is fixed in trailing wheel (18) axle bearing below; strut bar (9) length is greater than trailing wheel (18) radius, so can be connected to each other between two protection steamboats.

Because all there is the protection steamboat (10) of damping trailing wheel (18) both sides; the helping so do not choose; also can practice flying the wheelbarrow of riding alone, be unlikely to fall and fall, when the exercise wheelbarrow is ridden; can be adjusted to protection steamboat (10) one in front and one in back; very steady safety according to skill level, can be aligned the distance on protection steamboat (10) and ground when riding; in the time skillfully riding wheelbarrow, with regard to dismountable this protection steamboat (10).

Click's grip (16) all is equipped with at handle (12) two ends, the brake system of this cart adopts the cable brake braking, back brake adopts movable click's grip (16), as bicycle the time, click's grip (16) packs into handle (12), just can braking rear-wheel (18), as wheelbarrow the time, can take out click's grip (16), just can independent brake.

Compared with prior art, Multifunctional combination chainless two-wheel cycle has following advantages:

1, has bicycle, the function of wheelbarrow and handcart;

2, do not use chain, do not have chain rupture, fall the shortcoming of chain and greasy dirt;

3, the protection steamboat is equipped with in both sides, can practise separately riding of wheelbarrow, does not have and falls the thing of falling So;

4, adopt the cable brake braking, click's grip is housed on the handle;

5, in light weight, volume is little, and is for ease of maintenaince collapsible, is easy to deposit;

6, cost is low.
