The specific embodiment
Below in conjunction with specific embodiment, the present invention is specifically described.
Embodiment 1: as shown in Figures 1 to 8, a kind of go-kart with step-less adjustment function, as conventional go-kart, comprises dish 1, lower wall 2, and upper dish 1 is provided with backrest 3, and lower wall 2 is provided with wheels 4; Between upper dish 1 and lower wall 2, by adjustable upper dish 1, be connected with the Collapsible structure 5 of the spacing of 2 of lower walls.
Collapsible structure 5 comprises holder 501 and lever arm 502, and holder 501 is connected with lever arm 502 is scalable; In this example, holder 501 upper end open, mate with this opening that one end being connected with holder 501 on lever arm 502.Insert by this opening in the cavity of holder 501 that one end being connected with holder 501 on lever arm 502, and this cavity 503 mates with the size of that one end being connected with holder 501 on lever arm 502.
Holder 501 is fixed on lower wall 2, and described lever arm 502 is connected and fixed on dish 1.Described holder 501 is one-body molded with lower wall 2.In this example, holder 501 is plastic casing.
In this example, in upper dish 1, be provided with coil pipe 6, upper coil pipe 6 is firm with upper dish, is provided with lower coil pipe 8 in lower wall 2, and lower coil pipe and lower wall are fastening, are provided with stay pipe 7 in lever arm 502, and V-type spring leaf 701 is installed in stay pipe 7; Upper coil pipe 6 is fixedly connected with the upper end of stay pipe 7; The scalable connection of bend 801 of the lower end of stay pipe 7 and lower coil pipe 8 can be that insert in the bend 801 of lower coil pipe 8 lower end of stay pipe 7.The bend 801 of lower coil pipe 8 is positioned at holder 501.
Lever arm 502 comprises support enclosing cover 503, supports inner cap 504, supports inner cap 504 and stay pipe 7 fits, supports inner cap 504 and is fixed on support enclosing cover 503.
Holder 501 is provided with rotating regulating wheel 9, and regulating wheel 9 is uprightly placed, and the one side of regulating wheel 9 is provided with the regulating tank 11 arranging along involute 10, and involute 10 is to be located in the plane of regulating wheel 9 sides.That one end being connected with holder 501 on lever arm 502 is provided with locating dowel 505, and one end of described locating dowel 505 puts in regulating tank 11.Certainly locating dowel 505 also can be arranged to lever arm 502 on parts one-body molded.Regulating part 12 is connected with regulating wheel 9, by regulating part 12 use external force, drives, and regulating wheel 9 is rotated.Certainly regulating part and regulating wheel also can one-body moldedly be manufactured.In the improvement of this example, regulating part 12 is for regulating turn-knob, and regulating wheel 9 is connected with regulating turn-knob by rotating shaft 13, and rotating shaft is installed on holder 501, and regulating wheel is positioned at holder 501; Regulate turn-knob to be positioned at outside holder 501.
During work, when regulating turn-knob to clockwise rotate, regulating wheel rotates the gravity that overcomes upper dish, can make lever arm gradually raise, thereby realize upwards, regulates.When regulating turn-knob to rotate counterclockwise, can make lever arm gradually reduce, thereby realize downwards, regulate.Easy to adjust easy.If Fig. 8 is upper dish when the extreme lower position, regulating wheel and locating dowel location diagram.If Fig. 9 is upper dish while mediating, regulating wheel and locating dowel location diagram.If Figure 10 is upper dish when the extreme higher position, regulating wheel and locating dowel location diagram.
Operation principle: step-less adjustment function of the present invention is used the principle of involute to realize.Holder is connected with lever arm is scalable, and that is to say can be movable between holder and lever arm, when regulating wheel rotates, regulating tank and then rotates, and locating dowel is because one end is positioned at regulating tank, the position of locating dowel is changed, and this kind of position changes just in vertical direction, positive direction or negative direction, locating dowel shift in position like this, lever arm is change and then, in this example, stay pipes etc. are and then change also, just can make the height of dish change.Produce the function that rises or fall.And regulating tank arranges along involute, can make like this change of locating dowel position until the height of upper dish changes more smooth and easyly, and be linear, even if car has child, also can with child's height very easily, flexibly, cosily coordinate.The demand regulating is more easily realized.The present invention is simple in structure, uses parts few, and cost is low.
Embodiment 2: this routine feature is, described holder is fixed on dish, and described lever arm is fixed on lower wall.The position of holder and lever arm and embodiment 1 is exchanged, and implements principle in the same manner as in Example 1.
The present invention has the go-kart of step-less adjustment function, there is step-less adjustment function, upper dish regulates when rising or falling, regulating tank arranges along involute, can make like this change of locating dowel position until the height of upper dish changes more smooth and easy, and be linear, can with child's height very easily, flexibly, cosily coordinate.Needed parts are few, simple in structure, easy to manufacture.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
