Abstract
The invention discloses a self-sliding plate capable of exercising balance. A bracket base is arranged at the bottom of a pedal; a bracket is hinged with the bracket base; an axle is rotationally arranged on the bracket; a wheel is fixed on the axle; an inner engaged circular rack and an outer engaged circular rack are respectively in transmission connection with the axle through unidirectional gear transmission mechanisms; and front and rear supporting wheels are arranged below the bracket. Therefore, the scooter can be driven to run continuously when a user alternately treads the front and rear ends of the pedal, and can be in a balance state by coordination of double feet of the user during running; and the self-sliding plate has different sliding style compared with the conventional market sliding plate, can exercise the balance capability of the user and has strong entertainment and body-building effects.
Description
Technical field
The present invention relates to a kind of slide plate, particularly relate to a kind of self sliding board of tempering balance.
Background technology
The amusement shape slide plate of selling in the market mostly is under pedal, to be fixed with base, and support is installed on the base, and wheel shaft is installed on the support, and wheel is installed on the wheel shaft.When sliding, pin of user steps down on the pedal, and the another the feet step on the ground makes slide plate obtain the power that advances.Such slide plate has simple in structure, and has certain recreational.But such slide plate has the shortcomings such as balanced capacity that can not continue to slide (have only with pin and just can keep continuing to slide with constantly pedaling) and be difficult for taking exercise the user.
Summary of the invention
In view of the deficiency that background technology exists, the technical problem that the present invention will solve provides a kind of balanced capacity that can temper the user, and alternately back and forth pushing down on the pedal through front and back just to make the self sliding board of the taken exercise balance that slide plate continues to go.
In order to solve the problems of the technologies described above; The present invention adopts following technical scheme to realize: a kind of self sliding board of tempering balance; Comprise pedal, bracket base, support, wheel shaft, wheel, interior engagement arc-shaped rack and external toothing arc-shaped rack; On the bottom surface of pedal bracket base is installed; Described support and bracket base are hinged, and described wheel shaft is rotating rack-mount, are fixed with wheel on the wheel shaft; Engagement arc-shaped rack and external toothing arc-shaped rack in being fixed with on the bottom surface of described pedal; The center of circle of the hinged axle center of described support and bracket base, the center of circle of interior engagement arc-shaped rack and external toothing arc-shaped rack is positioned on the same axial line, and described interior engagement arc-shaped rack, external toothing arc-shaped rack are in transmission connection through gear one-way driving mechanism and wheel shaft respectively, and the below of support is equipped with the back and front supporting wheel.
Under the pedal of the present invention bracket base is installed; Described support and bracket base are hinged; And mesh arc-shaped rack and external toothing arc-shaped rack under pedal, being equipped with, because the center of circle of the center of circle of the hinged axle center of support and bracket base, interior engagement arc-shaped rack and external toothing arc-shaped rack is positioned on the same axial line; Therefore when the front end that pushes down on the pedal, pedal rotates before the jointed shaft mind-set of support and bracket base, through interior engagement arc-shaped rack and gear one-way driving mechanism with transmission of power to wheel shaft, thereby the drive wheel to overtake; When the rear end that pushes down on the pedal, pedal rotates after the jointed shaft mind-set of support and bracket base, gives wheel shaft through external toothing arc-shaped rack and gear one-way driving mechanism with transmission of power, drives wheel to overtake.(second kind of the present invention, the third embodiment: the front end that pushes down on the pedal, give wheel shaft through external toothing arc-shaped rack and gear one-way driving mechanism with transmission of power, drive wheel to overtake; The rear end that pushes down on the pedal is given wheel shaft through interior engagement arc-shaped rack and gear one-way driving mechanism with transmission of power, thereby drives wheel to overtake).The present invention needs the cooperation of user's both feet and health just can make it be in poised state; And can make slide plate continue the state that goes through the front and back end that both feet alternately back and forth push down on the pedal; With the slide plate of selling in the market the different styles that slides is arranged, in the process of going, have stronger body-building and entertainment effect.
