Abstract
The utility model relates to a groove cambered surface three-dimensional heart-shaped rolling toy which comprises a base with a circular arc surface; a circular-arc-shaped groove is arranged on the top of the base with the circular arc surface; the top of the circular-arc-shaped groove is a circular arc surface; the bottom of the circular-arc-shaped groove is a circular arc surface; a three-dimensional heart-shaped rolling body is embedded in the circular-arc-shaped groove; the three-dimensional heart-shaped rolling body is of a hollow structure; an eccentric block is fixed on the inner wall of the three-dimensional heart-shaped rolling body; and the outer wall of the three-dimensional heart-shaped rolling body is provided with a circular-arc-shaped protrusion which is positioned in the circular-arc-shaped groove. The three-dimensional heart-shaped rolling body of the groove cambered surface three-dimensional heart-shaped rolling toy provided by the utility model can roll back and forth along the circular-arc-shaped grove through the circular-arc-shaped protrusion under the effect of the eccentric block internally, and finally the three-dimensional heart-shaped rolling body stops at the circular-arc-shaped groove, namely the top end of the base with the circular arc surface under the frictional force effect of the circular-arc-shaped groove, and not only can be provided for the entertainment for children, but also can be placed at home as decoration.
Description
Technical field
The utility model relates to the three-dimensional heart-shaped rolling toy of a kind of groove cambered surface.
Background technology
At present the toy for children function ratio is more single, can only supply entertainment for children, and the market do not have a kind of can the free rolling toy.
The utility model content
The utility model provides a kind of groove cambered surface three-dimensional heart-shaped rolling toy to the above-mentioned deficiency that existing toy for children exists.
The technical scheme that the utility model solves the problems of the technologies described above is following: the three-dimensional heart-shaped rolling toy of a kind of groove cambered surface comprises the base with arc surface; Said top with arc surface base is provided with arc-shaped groove; The top of said arc-shaped groove is an arc surface; The bottom of said arc-shaped groove is an arc surface, and said arc-shaped groove is embedded with three-dimensional heart-shaped rolling element, and the heart-shaped rolling element of said solid is a hollow-core construction; Be fixed with a weighting block on the inwall of the heart-shaped rolling element of said solid; Have circular-arc projection on the outer wall of the heart-shaped rolling element of said solid, said circular-arc projection is positioned at arc-shaped groove, and the two ends of said arc-shaped groove respectively are provided with a position limiting structure.
The beneficial effect of the utility model is: roll to and fro along arc-shaped groove through circular-arc projection under the effect of weighting block within it of the three-dimensional heart-shaped rolling element of the three-dimensional heart-shaped rolling toy of the utility model groove cambered surface; At last under the frictional force effect of arc-shaped groove, be parked in the top that arc-shaped groove promptly has the arc surface base; Not only can also put at home as ornament for entertainment for children.
Description of drawings
Fig. 1 is the partial sectional view of the three-dimensional heart-shaped rolling toy of the utility model groove cambered surface.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1; The three-dimensional heart-shaped rolling toy of said groove cambered surface comprises the base 1 with arc surface, and said top 1 with arc surface base is provided with arc-shaped groove 2, and the top of said arc-shaped groove 2 is an arc surface; The bottom of said arc-shaped groove 2 is an arc surface; Said arc-shaped groove 2 is embedded with three-dimensional heart-shaped rolling element 3, and the heart-shaped rolling element 3 of said solid is a hollow-core construction, is fixed with a weighting block 4 on the inwall of the heart-shaped rolling element 3 of said solid; Has circular-arc projection 5 on the outer wall of the heart-shaped rolling element 3 of said solid; Said circular-arc projection 5 is positioned at arc-shaped groove 2, and the two ends of said arc-shaped groove 2 respectively are provided with a position limiting structure 6, can be used to prevent three-dimensional heart-shaped rolling element 3 dropping of appearance accidentally.
The three-dimensional heart-shaped rolling toy of the utility model groove cambered surface in use; Can the heart-shaped rolling element of solid be placed on an end of groove; And make weighting block in it be positioned at that part departs from directly over the three-dimensional heart-shaped rolling element inwall and near the position on base top with arc surface; Open openhanded again; So at this moment the center of gravity of three-dimensional heart-shaped rolling element is owing to will roll to the direction on the base top with arc surface along the part of arc surface in the effect of gravity at higher position; Center of gravity is minimum and because inertia can continue to roll to another part of arc surface, when being rolled to the other end of groove, thereby can repeat the rolling back and forth that said process is realized three-dimensional heart-shaped rolling element when having the base top of arc surface; The last top that under the frictional force effect of arc surface, is parked in base with arc surface, this moment weighting block be positioned at three-dimensional heart-shaped rolling element inwall under.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
