Abstract

The utility model relates to an improved sliding plate which can move without depending on inertia when a plate is stepped on. Lower opening parts of two through holes of the plate body are respectively fixed with a bracket; the interior of a cylinder body of each bracket is provided with a shaft bowl and a ball; a rotary shaft connected with a shaft gear is threaded through the cylinder, the lower end is connected with a wheel shaft, and the upper end is connected with cover plates; both ends of the wheel shaft are respectively connected with a roller; the plate body is inserted with a ring slot body whose interior is provided with the ball; the lower bottom surfaces of the cover plates are abutted to the ball and keep distance with the plate body. Two rollers of the sliding plate have the same structures; two feet step on the two cover plates of the sliding plate, and changes the gravity center in a coordinate mode to rotate, and the sliding plate can move towards one direction; simultaneously, the human body can obtain body-building exercises of a torsion pendulum mode.

Description

A kind of improved slide plate

The utility model relates to slide plate.

Existing skateboarding apparatus, its wheel relative fixed be in plate body, this slide plate is through initially applying a power, slides by inertia, when both feet are stepped on onboard simultaneously, can not apply the power that slides to slide plate again, unless pedal ground with leg again.Because the wheel relative fixed, it is single that this slide plate slides mode, and adaptive with it human motion mode is also more single.

The purpose of this utility model is to provide a kind of improved slide plate, and the core wheel of two pairs of wheels of this slide plate is unfixing with respect to plate body, and twisting just can constantly apply to plate body and slide power about both feet were stepped on onboard simultaneously, and slide plate is slided towards a direction.

The technical scheme of a kind of improved slide plate of the utility model is to be provided with plate body and roller, its special character is, plate body is corresponding to the axis and be symmetrical in equator and be provided with two through holes, the end opening position of each through hole axially is provided with a support accordingly and is fixed in plate body, mid-stent is a cylindrical shell, on this cylindrical shell, the lower end is built-in with axle bowl and lower shaft bowl respectively, rotating shaft passes axle bowl and lower shaft bowl and is provided with, be arranged with the axle gear in the rotating shaft in the plate body through hole, be equipped with ball between last axle shelves and the last axle bowl, in the rotating shaft and be arranged with the lower shaft shelves, be equipped with down ball between lower shaft shelves and the lower shaft bowl, on, the top is provided with steel pipe between the lower shaft bowl, be embedded with above the plate body annular groove body radially from rotating shaft one distance and with the coaxial heart of rotating shaft, be equipped with this ball vault of ball plane on the plate body in the annular groove body, cover plate is fixed in rotating shaft with its centre and is provided with in ball with its bottom surface closing, the rotating shaft lower end vertically is associated with wheel shaft with it, and the wheel shaft two ends are fixed with roller.

A kind of improved slide plate of the utility model, because plate body is positioned at the axis and is symmetrical in equatorial two through hole end opening positions and respectively is fixed with the support that a middle part is a cylindrical shell, in this axially corresponding plate body through hole and support cylindrical shell, the axle shelves that are provided with rotating shaft and link with it, this rotating shaft can be according to just last together with the axle shelves, following ball is with respect on set, the lower shaft bowl rotates, this rotation takes place simultaneously with the rotation that is coupled to the cover plate of rotating shaft, so, when stepping on a pin (another pin is stepped on another cover plate in same structure) when board plane rotate to drive cover plate and rotates in cover plate, rotating shaft is also rotated together with the wheel shaft that its lower end joined, the roller that the wheel shaft two ends are joined will roll by opposite direction mutually, when pin is stepped on the deviation of gravity center rotating shaft core of cover plate, this roll displacement of two rollers is just unequal, thereby can make rotating shaft except that rotating, produce the displacement of a translation, two pair rollers move respectively, and slide plate is moved towards a direction, will remake description to this below in conjunction with diagrammatic sketch.Because not needing just can moving slide board by the inertia that promotes first, also not strict to the requirement in place so the manner of this slide plate is comparatively various, and the people steps on and mostly is health when movable onboard and twists posture, becomes a kind of good fitness and body-building activities.

Below in conjunction with accompanying drawing embodiment of the present utility model is described.

Fig. 1 is a kind of improved skateboard schematic diagram of the utility model;

Fig. 2 is the A-A or the B-B cutaway view of Fig. 1 slide plate;

Fig. 3 is the C-C cutaway view of Fig. 1 slide plate.

1 one kinds of improved slide plates of embodiment, plate body 15 is corresponding to the axis and be symmetrical in equator and be provided with two through holes, the end opening position of each through hole axially is provided with a support 7 accordingly and is fixed in plate body, support 7 middle parts are cylindrical shell, on this cylindrical shell, the lower end is built-in with axle bowl 14 and lower shaft bowl 13 respectively, rotating shaft 2 passes axle bowl and lower shaft bowl and is provided with, be arranged with axle shelves 3 in the rotating shaft and be positioned at the plate body through hole, be equipped with ball 8 between last axle shelves and the last axle bowl, in the rotating shaft and be arranged with lower shaft shelves 11, be equipped with down ball 10 between lower shaft shelves and the lower shaft bowl, on, the top is provided with steel pipe 9 between the lower shaft bowl, be embedded with above the plate body annular groove body 5 radially from rotating shaft 2 one distance and with the rotating shaft 2 coaxial hearts, be equipped with ball 4 these ball vaults plane on the plate body in the annular groove body, cover plate 1 is fixed in rotating shaft 2 with its centre and is provided with in ball 4 with its bottom surface closing, and rotating shaft 2 lower ends vertically are associated with wheel shaft 16 with it, and the wheel shaft two ends respectively are fixed with a roller 12.

A pair roller schematic diagram that is coupled to same wheel shaft of representing referring to Fig. 3.Be right against rotating shaft 2 when rotating when pin steps down on the cover plate center of gravity, cover plate rotates an angle together with rotating shaft 2 and wheel shaft 16, and mechanism becomes state 2 by state 1, and rotating shaft 2 does not produce the translation displacement except that rotating an angle; When pin steps down in deviation of gravity center rotating shaft 2 on the cover plate, when center of gravity is corresponding to the E point as shown, the roller frictional force over the ground of ordering near E increases, and the displacement that rolls left is little, and the roller of ordering away from E frictional force over the ground reduces, and to roll displacement big on the right side, be equivalent to produce a kind of rotation of ordering around E, at this moment, rotating shaft 2 also produces a translation except that rotating, move to D ' point from the D point.Another pin is stepped in its deviation of gravity center of another cover plate in the opposite side of ordering relative to E and is rotated, and makes another rotating shaft by the equidirectional displacement, and both feet are weight shift then, and wheel stirs work, and slide plate is constantly moved, and slide plate is moved towards other direction; Simultaneously, health is rocking and is moving, and can play good amusement and body-building effect.
