CN2778665Y - Single-shaft double flywheel apparatus for seesaw sleigh - Google Patents

Abstract

The utility model relates to a single shaft and double fly wheel device for a slide vehicle of a seesaw, which belongs to the class of entertainment slide vehicles. At present, slide vehicles of seesaws used for entertainment are stressed to run in one way. The utility model is formed by connecting a seesaw, a front wheel, a rear wheel, fly wheels and chain racks. When the utility model slides, the unsteady slide of the utility model is caused by poor balance effect because feet strenuously tread the ground for doing action. The fly wheels meshed by two chain racks and chains are arranged on the shaft under the seesaw in the utility model for solving the problem, and thus, two fly wheels become coaxial double fly wheel structure that the two fly wheels are tightly locked in one same direction and freely rotate in one same direction. When the utility model is used, a vehicle body can run forward continuously as long as the pedal is treaded down forward and back by one foot, and thus, power can be saved and the running speed of the sliding vehicle is increased. Because the utility model has simple structure and convenient operation, the utility model can be used in other manual power vehicles with spacing structure besides sliding vehicles.

Description

A kind of single shaft round trip flight wheel apparatus that is used for the seesaw scooter

Technical field:

The utility model relates to a kind of single shaft round trip flight wheel apparatus that is used for the seesaw scooter, belongs to amusement and slides vehicle.

Background technology:

Body-building apparatus is varied, and scooter is as the instrument of body-building recreation, liked by the teenager, that sells on the market in the existing technology has single leg scooter and a double-legged seesaw type scooter, wherein single leg scooter is to do power with one to move forward by car foot-operatedly, and double-legged seesaw scooter, it is same that both feet stand in ahead running on the pedal with pedaling then before the pin, above-mentioned scooter is owing to lack flywheel gear, can not advance by car by the front and back pedal, seem very inconvenient, and recreational also comparatively dull.

The utility model content:

The utility model purpose is in order to overcome above-mentioned shortcoming, and a kind of single shaft round trip flight wheel apparatus that is used for the seesaw scooter that provides, no matter this device is installed on the scooter toward front running board or to back step, and scooter is slided forward, laborsaving convenience is recreational strong.

For achieving the above object, the technical solution adopted in the utility model is such:

It is that two bolts hole are housed on oblong seesaw transversal centerline, also be provided with two corresponding bolts holes on the axle on cylindrical, and will lift up with last axle fixing with bolt, two ends at last axle respectively are provided with bearing, outside bearing, is furnished with bearing shell respectively, bearing shell is fixed on the mullion of rectangular base frame with bolt, seesaw center line rear is provided with four bolts hole and two semicircle chains, corresponding positions is equipped with four bolts hole in the chain frame upper end, make four of the chain frame upper end to be bolted on the seesaw, each is fixing a chain with bolt above the chain for each, and a flywheel interlock with it is housed on the every chain, is respectively equipped with bearing in two trailing wheels, bearing shell and underframe bolt, the lower shaft two ends are provided with two trailing wheels, and by bolt or be weldingly fixed on above the lower shaft, underframe and handlebar are welded to each other with stirrup.

Owing in the coaxial round trip flight wheel construction described in the utility model two flywheels are installed on the chain of underframe top, underframe and last axle weldering knot are together, and two same direction lockings of flywheel, same direction rotates freely, therefore, can be as the double dynamical transmission of scooter, promptly when an end of seesaw is stepped on downwards, flywheel, but link chain mechanism transferring power, a rotating band motor-car is travelled forward, and at this moment flywheel is in reverse idling conditions, when the other end of seesaw is stepped on the time downwards, flywheel one link chain mechanism transfer motion power drives the lower shaft rotation, scooter is travelled forward, and flywheel is in reverse idling conditions, each downward stroke of seesaw two ends can both make the seesaw scooter travel forward like this, thereby guaranteed the continuous running of seesaw, can be laborsaving, improved the scooter running velocity again, also overcome traditional seesaw scooter and had only when stepping on the rear end downwards, just moving once of seesaw, and preceding stepping on only is in the drawback of stepping on sky.

The utility model compared with prior art has distinguishing feature:

Because the utility model is equipped with two flywheel transmission devices by the chain interlock on axle, this mechanism can drive car and travel forward, be seesaw an end by under when stepping on, the car body flywheel can make a rotating band motor-car travel forward, this moment between another flywheel be in reverse idling conditions.When the other end of seesaw is stepped on downwards, flywheel drives the axle rotation again can make scooter travel forward equally, flywheel still is in reverse idling conditions, each decending stroke at seesaw two ends can both make and lift up the scooter maintenance to front slide like this, thereby guaranteed the continuous running of seesaw, so promptly laborsaving, improved the scooter running velocity again, change when stepping on the seesaw scooter before the tradition and only stepping on downwards in the rear end, seesaw could move once, and front end is in when stepping on and steps on empty drawback.This in addition structure also can be used in other man power car that has position limiting structure.

Description of drawings:

Fig. 1 is that the utility model integral structure is illustrated attached view.

Fig. 2 is the utility model structural representation front elevation.

Among the figure by 1, seesaw, 2, go up axle, 3, chain frame, 4, flywheel, 5, lower shaft, 6, trailing wheel, 7, handlebar, 8, front-wheel, 9, underframe forms.

The specific embodiment:

The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.

In Fig. 1, oblong seesaw 1 transversal centerline is provided with bolt hole, also be provided with two corresponding bolts holes on the axle 2 on cylindrical, by bolt seesaw 1 and last axle 2 are fixed, seesaw 1 center line rear portion is provided with bolt hole, in relevant position, semicircle chain frame 3 upper end two bolts hole are arranged also, the upper end of chain frame 3 is fixed by bolts on the seesaw, article two, chain is with bolt or be weldingly fixed on the chain frame 3, chain and flywheel 4 teeth are engaged, two flywheels 4 are welded on cylindrical lower shaft 5 middle parts, be respectively equipped with bearing and bearing shell in two trailing wheels 6, bearing shell and underframe 9 are used bolt, and two trailing wheels 6 are equipped with at lower shaft 5 two ends, by being bolted on the lower shaft 5, underframe 9 is welded to each other with handlebar 7 usefulness stirrups.

Claims (1)
