Description

Cycle with slide plate

The vehicle that the utility model relates to a kind of amusement, body-building, rides instead of walk, specifically cycle with slide plate.

At present, Kickboard Scooter is as the instrument of amusement, body-building, the wind whole world of rubbing.Because the advantage of its structure must stride forward to the vehicle of riding instead of walk.Must pedal on the ground with pin in order to improve Kickboard Scooter, a segment distance can advance.Britain has loaded onto driving engine this car, has increased speed, in conjunction with its structural advantage, makes its sales volume surge.But because too high speed crisscrosses on the road, the hidden danger of safety is arranged in fact, two-cycle driving engine is again air-polluting source.The most important makes it can not work as Kickboard Scooter again and uses, and lost the effect of amusement, body-building at all.

The purpose of this utility model then is the problem that exists at above-mentioned prior art, has designed a kind of effect that amusement and body-building can not only be provided as Kickboard Scooter, and can also be the same with bicycle can step on the cycle with slide plate walked with manpower.

The purpose of this utility model can reach by following measure:

A kind of cycle with slide plate, comprise steering hardware, body installation, mobile devices, it is characterized in that above the trailing wheel 14 of cycle with slide plate, change speed gear box 11 being housed, about in the change speed gear box 11 two levers 12 by axle A with surmount ratchet 15 and connect, the front end of two levers 12 is equipped with step 13, surmounting ratchet 15 connects with minor sprocket 17 on the B by chain 16, hinge wheel 18 is an integral body with minor sprocket 17, hinge wheel 18 connects with minor sprocket 20 on the A by chain 19, surmounting ratchet 21 is an integral body with minor sprocket 20, surmounts ratchet 21 and connects with minor sprocket 23 on the axle C by chain 22, and trailing wheel 14 and minor sprocket 23 are an integral body, spring 24 upper ends are fixed on the extension arm of lever 12, and the lower end is fixed on the shell of a C or change speed gear box 11.

The purpose of this utility model can also reach by following measure:

Step 13 links to each other with lever 12 suspensions by the axle at two ends;

Step 13 is designed to arc.

The utlity model has following advantage:

To turn to rideability good in order making,, to have strengthened the casterangle of preceding steering hardware, and strengthened the distance of point of crossing, steering stability of the present utility model can be equated with bicycle to front wheel spindle according to the principle of steering stability.In order to cooperate the shear knife of big casterangle, increase the intensity of front frame, and make volume after folding little, neat again, and be designed to folding mode downwards.

Because the device of change speed gear box, make cycle with slide plate of the present utility model by can only pedaling on the ground and become and both can pedal and can step on pin as bicycle, by unilateral can only amusement, body-building can instrument be the cycle with slide plate of one to collection amusement, body-building, the friendship of riding instead of walk.

The utility model volume little, in light weight (about seven kilograms), can fold, center of gravity low (having only 5 centimetres), so safe, practical, be daily travelling and go up downstairs, go up down-hill useful tool.

Fig. 1 is the utility model structural representation.

Fig. 2 is a gearbox designs scheme drawing among Fig. 1.

Below in conjunction with accompanying drawing the utility model is further described:

One, steering hardware: comprise handlebar 1, telescopic rod 2, gripping sleeve 3, stationary pipes 4, steering bearing sleeve pipe 5, link rod 6, front-wheel jaw 7 and front-wheel 8 compositions.Two two ends suitable for reading that handlebar 1 inserts telescopic rod 2, each is fixed with two spring pins, and telescopic rod 2 inserts in the gripping sleeve 3, degree of tightness check screw D, the height of scalable handlebar 1, the bottom of gripping sleeve 3 is enclosed within stationary pipes 4 and weldering is dead, inserts the suitable for reading of front-wheel jaw 7.Front-wheel jaw 7 inserts in the bearing inner ring that is fixed in the steering bearing sleeve pipe 5, and use nut locking, front-wheel 8 is contained in the lower end of front-wheel jaw 7, link rod 6 is welded on and draws into whole steering hardware on the steering bearing sleeve pipe 5, and connect with two pin K of front frame 9 usefulness of body structure, and the below that rotates to vehicle body 10 that it can be whole is folded up by the K point, in order to carrying (seeing that Fig. 1 dotted line partly is the shape after folding).

Two, body installation: the front end of vehicle body 10 is welded as the fixedly front frame 9 of steering hardware, the change speed gear box 11 of rear end welding mobile devices, and trailing wheel 14 is installed, the cycle with slide plate that makes it become the manned load-bearing of energy and do mass motion.

Three, mobile devices: change speed gear box 11 provides the motion-promotion force of cycle with slide plate, its structure and principle of work be as shown in Figure 2: by lever 12 drive A axles when step 13 is stepped on downwards and rotate, surmounting ratchet 15 fixes with axle A, so the minor sprocket 17 that drives on the B axle by chain 16 rotates, hinge wheel 18 is an integral body with minor sprocket 17, so minor sprocket 20 that hinge wheel 18 drives on the A axle by another chain 19 again, another surmounts ratchet 21 is whole with minor sprocket 20, so surmounting ratchet 21 (does not draw on Fig. 2, marked label) again by the minor sprocket 23 on the trailing wheel 14 on an other chain 22 drive C axles, because trailing wheel 14 is whole with minor sprocket 23,, trailing wheel 14 advances so rotating the whole cycle with slide plate of drive.Change from step 13 input each second 1/5, by three grades of raising speeds during to minor sprocket 23 outputs, speed ratio is 21.7 6: 1, promptly changes each seconds 4.35, is 10 centimetres according to wheel diameter Φ and calculates, speed per hour Yue Keda 5 kms.Simultaneously, can adorn a movable seat cushion on the change speed gear box, can pull out to be seated when needing and travel.Because its center of gravity is low, so it is safe especially to travel.

The later-model working process of this reality is as follows:

User's both hands are being held handlebar 1, any pin vehicle body 10 of standing, and the another pin can be pedaled ground, and car is started.As using, can continue to advance with the feet step on the ground when Kickboard Scooter.As changing walking manner, can divide front and back to go up vehicle body 10 in the station simultaneously by both feet.Set foot on step 13 with the heel position of the pin in back this moment, and the kinetic energy of step is after the change speed gear box speed change when stepping on downwards, and the output power is given trailing wheel 14, promotes front-wheel 8 again, makes its integral body make continuous forward movement.When step 13 is stepped on earth, when promptly running into vehicle body 10, unclamp used pin, step 13 is promptly resetted by spring 24, can enter next working process thus.The design-calculated speed per hour is about per hour about 5 kms at present.

Handlebar 1 can be regulated height by gripping sleeve 3 according to the height of user's stature.After finishing using, can the predecessor be rotated to body bottom section by changing pin K, make volume fold into 720 * 250 * 150, carrying very easily upstairs or collection.

Front and back wheel all is equipped with brake, even when descending is walked at a high speed, with hand by the line brake strap moving before and after brake, braking is very much reliable.
