Abstract

The utility model relates to a quadrangular frustum pyramid groove ball type rolling toy. The rolling toy comprises a quadrangular frustum pyramid-shaped foundation; the top of the quadrangular frustum pyramid-shaped foundation is provided with a semi-cylindrical groove; a ball is embedded into the groove and has a hollow structure; the inner wall of the ball is fixed with a weighing block; and the outer wall of the ball is provided with a semi-cylindrical arc bulge which is positioned in the groove. According to the rolling toy, the ball can roll along the groove back and forth through the arc bulge under the action of the weighing block in the ball and finally stops on the groove under the action of frictional force of the groove, and the weighing block is positioned below the inner wall of the ball, so that children can play the toy, and the toy used as an ornament is placed in home.

Description

A kind of truncated rectangular pyramids groove ball type rolling toy

Technical field

The utility model relates to a kind of truncated rectangular pyramids groove ball type rolling toy.

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 truncated rectangular pyramids groove ball type 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: a kind of truncated rectangular pyramids groove ball type rolling toy comprises the base of truncated rectangular pyramids shape; The top of said truncated rectangular pyramids shape base is provided with the groove of the semicolumn bodily form; Said groove is embedded with spheroid, and said spheroid is a hollow-core construction, is fixed with a weighting block on the inwall of said spheroid; The circular-arc projection that has the semicolumn bodily form on the outer wall of said spheroid, said circular-arc projection is positioned at groove.

The beneficial effect of the utility model is: roll to and fro along groove through circular-arc projection under the effect of weighting block within it of the spheroid of the utility model truncated rectangular pyramids groove ball type rolling toy; At last be parked on the groove under the frictional force effect of groove and weighting block be positioned at sphere inner wall under; 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 utility model truncated rectangular pyramids groove ball type rolling toy.

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; Said truncated rectangular pyramids groove ball type rolling toy comprises the base 1 of truncated rectangular pyramids shape, and the top of said truncated rectangular pyramids shape base 1 is provided with the groove 2 of the semicolumn bodily form, and said groove 2 is embedded with spheroid 3; Said spheroid 3 is a hollow-core construction; Be fixed with a weighting block 4 on the inwall of said spheroid 3, have the circular-arc projection 5 of the semicolumn bodily form on the outer wall of said spheroid 3, said circular-arc projection 5 is positioned at groove 2.

The utility model truncated rectangular pyramids groove ball type rolling toy can be placed on spheroid one end of groove in use, and makes weighting block in it be positioned at that part departs from directly over the sphere inner wall and near the position of the groove other end; Open openhanded again; So at this moment the center of gravity of spheroid is owing to will roll to the direction of the other end along an end of groove in the effect of gravity at higher position, in the time of under weighting block is positioned at sphere inner wall center of gravity minimum and since inertia can continue to roll to the other end of groove, when being rolled to the other end of groove; Thereby meeting repetition said process is realized the rolling back and forth of spheroid; Under the frictional force effect of groove, be parked on the groove at last, this moment weighting block be positioned at sphere inner wall under, in addition; In whole rolling process, circular-arc projection can prevent spheroid dropping in rolling process all the time in groove.

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.

Claims

1. a truncated rectangular pyramids groove ball type rolling toy is characterized in that, comprises the base of truncated rectangular pyramids shape; The top of said truncated rectangular pyramids shape base is provided with the groove of the semicolumn bodily form; Said groove is embedded with spheroid, and said spheroid is a hollow-core construction, is fixed with a weighting block on the inwall of said spheroid; The circular-arc projection that has the semicolumn bodily form on the outer wall of said spheroid, said circular-arc projection is positioned at groove.
