Abstract

The utility model relates to a dry skating vehicle with a vehicle frame supported by three or more than three wheels. A front fork and a front wheel are installed on the front part of the vehicle frame, and a standpipe for the front fork and handle bars are used for controlling direction. A rear shaft, a gear wheel for the rear shaft and a free wheel are instilled in a rear pipe of the vehicle frame, and rear wheels are installed on two end parts of the rear shaft. The rear part of the vehicle frame is a vehicle body, an intermediate shaft is installed in the vehicle body, and a gearwheel and a free wheel gear wheel are installed on the intermediate shaft. A pair of fan-shaped gear wheels are also arranged in the vehicle body and are installed on shafts for the fan-shaped gear wheels, the shafts for the fan-shaped gear wheels are right above the rear shaft, a circular hole is arranged on the intermediate section of each of the shafts, and a rocker arm is installed in the hole. A pair of pedals, cranks and rocker arms are arranged on the vehicle body, and the cranks and the rocker arms are in rigid connection with the fan-shaped gear wheels. When people stand on the pedals and alternate left feet and right feet to support bodies, a left pedal and a right pedal can perform seesaw motion; through a transmission chain which comprises the crank, the rocker arms, the fan-shaped gear wheels, the free wheel gear wheel, the gearwheel, the gear wheel for the rear shaft, the rear shaft and the free wheel on the rear shaft, motive power is transmitted to rear wheels to realize that the rear wheels of a vehicle roll and slide forwards.

Description

The dry skating scooter

Roller skate is that numerous teenagers like a good entertainment body-building activity, normally slides by roller skate.

The purpose of this utility model is, a kind of have three or three above pulley bearing vehicle frames are provided, be equipped with in the vehicle frame front portion front fork, front-wheel and handlebar with controlling party to, one group of gear, flywheel gear and axle are housed, by stepping on the dry skating scooter that two pedal drive cars move ahead up and down repeatedly at the vehicle frame rear portion.

Accompanying drawing 1 is a lateral plan of the present utility model, and accompanying drawing 2 is birds-eye vieies of the present utility model.

In conjunction with the accompanying drawings structure of the present utility model and principle of work are described below:

Front fork (1), front-wheel (2), vertical tube of front fork (3) and handlebar (17) are equipped with in vehicle frame (5) front portion, connect with lock screw (4).In vehicle frame (5) rear cross tube rear axle (23) is housed, rear axle gear (15), trailing wheel (16) is equipped with at rear axle (23) both ends, and trailing wheel (16) supports with bearing (28) with rear axle (23).Also be shaped on 2 upright arms (14) at vehicle frame (5) rear portion, sector shaft (21) is housed between two arms, quadrant gear (11) is equipped with at the axle two ends, the axle stage casing is shaped on hole, a garden and the rocking arm of packing into (13), is shaped on 2 bulbs (20) on the rocking arm (13) and is filled to respectively in the hole, microscler garden on two quadrant gears (11).Electric crank of pedal (8) (10) and rocking arm (13) supporting, two pedals are in same plane and are parallel to ground.Crank (10) becomes to be rigidly connected with quadrant gear (11).When pedal (8) is up and down reciprocatingly stepped on, drive quadrant gear (11) by crank (10) and rocking arm (13) and do swing up and down reciprocatingly---when a side pedal moves downward; homonymy one end of rocking arm; hole, microscler garden acts on application force on the homonymy rocking arm bulb in the direct effect of pedal with by quadrant gear, makes downward tilting; Rocking arm (13) is supporting with the hole, garden in sector shaft (21) stage casing; When this end had a downwarp, the other end of rocking arm upwarped, and the bulb on this end holds up this quadrant gear and crank simultaneously by the hole, microscler garden of quadrant gear, made that this side pedal and respective side pedal are done synchronously, upward movement in opposite directions.Flywheel gear (18) on the tween drive shaft (19) is driven by quadrant gear (11), flywheel gear (18) drives big gear wheel (9) again, big gear wheel (9) drives rear axle gear (15) again and rear axle (23) rotates, by flat key (26), flywheel (27) and hub (29), drive trailing wheel (16) again and roll, thereby realize that car slides forward.

In pipe inboard, two ends, vehicle frame (5) back cramp bar (25) and brake control lever (12) are housed,, slide safety with guarantee by flexible axle (22) and handlebar (17) control brake.

The driving section has protective cover (7) bag to protect to see that whole transmission device is clean and tidy to keep, safety.This partly is commonly called as vehicle body.

Unclamp clamp handle (6), handlebar (17) can fold back.

The utility model modern design is skillfully constructed, and carries and deposits conveniently.
