Abstract
A sphere rotating and turning over for 180 degrees is composed of a large spherical crown (1), a small spherical crown (2), and fillers (3). The sphere is characterized in that a hollow spherical body (for example, a ping pang ball) is cut at 2/3 to 4/5 of the diameter to form the large spherical crown (1) and the small spherical crown (2); the inner space of the large spherical crown (1) is partially or completely filled with the soft fillers (3); liquid glue is used to fix the fillers (3) with the large spherical crown (1) and to coat the inner side edges of the large spherical crown (1) and the small spherical crown (2); the edges of the small spherical crown (2) and the large spherical crown (1) are fixed together again to restore the appearance of the original spherical body; and a colored oily pen is used to paint the area of a top portion (4) of the small spherical crown (2) for distinguishing the small spherical crown (2) from the large spherical crown (1). The unique point of the sphere is that unlike instruments in convenient tests, the spherical body can rotate and turn over for 180 degrees. The sphere is very simple to manufacture and obvious in effect. The sphere can have more educating functions when being popularized in teaching and also can be popularized to the field of toys.
Description
Technical field
The utility model patent relates to the demonstration friction square to the lecture experiment instrument of rotary body upset Changing Pattern, belongs to the physical experiment apparatus field.
Background technology
Ripe egg is holded up when it allows it behind the vertical axes High Rotation Speed in horizontal table top gradually, continues to rotate around vertical axes behind an angle of 90 degrees that namely overturns.For complete hard ball, generally anyway allow it rotate around vertical axes, we can't see it and can overturn, as if this give us an illusion, only have traditional upset gyro could in rotary course, realize turning over the turnback angle, for cultivating student's initiative spirit and the ability of practice, teach through lively activities, need to provide the practical plan of more quick Fabrication upset gyro sort, the inventor herein periodical " Physical Experiment " 2002.3 " can fall gyro mechanism research with make " in provide the scheme of the general angle of upset, but manufacture craft relative complex, how to accomplish to be convenient to student's self-control or improvement, simple, the ball of 180 degree is stood up in rollover effect rotation good and failure rate is low, and this patent will address this problem.
Summary of the invention
The utility model patent is to solve the ball that stands up of using under classroom or the class, solves emphatically the spheroid turnover technology.
The utility model patented technology scheme: the ball of 180 degree is stood up in a kind of rotation, is made of large ball prefix, little spherical crown and filling material etc.It is characterized in that a hollow ball (such as, soldier's pang ball etc.) is cut into large ball prefix and little spherical crown at 2/3 to 4/5 place of diameter; With space segment in the large ball prefix or all put completely soft filling material, with liquid glue filling material and large ball prefix are fixed, and smeared large ball prefix and bead hat inside edge with glue; Little spherical crown and large ball prefix edge retightened recover the external sight of protocorm together, spread upon on the bead hat top area to be different from large ball prefix with band look oil pen again.
During experiment, ball is placed on the surface level, because barycenter is in the large ball prefix part, the large ball prefix contact plane, bead hat top twists spheroid with hand and rotates around vertical axes up, just can see that spheroid begins to stand upside down in rotation, along with large ball prefix is holded up, bead hat top contact plane begins stable rotation, has realized that spheroid turns over turnback.
Its unique distinction of the utility model patent is different from existing experiment, has realized that the spheroid rotation stands up 180 degree.Make extremely simple and easy, successful, promotion conference increases more educational function in teaching, also can be generalized to the popular science toys field.
Description of drawings
Accompanying drawing is the structure A-A diagrammatic cross-section of the utility model patent.Wherein: (1) is large ball prefix, and (2) are little spherical crowns, and (3) are filling materials, and (4) are bead hat tops
Embodiment
Such as accompanying drawing: the balls of 180 degree are stood up in a kind of rotation, by large ball prefix (1), little spherical crown (2) and filling material (3) formation.It is characterized in that a hollow ball (such as, soldier's pang ball etc.) is cut into large ball prefix (1) and little spherical crown (2) at 2/3 to 4/5 place of diameter; With the interior space segment of large ball prefix (1) or all put completely soft filling material (3), with liquid glue that filling material (3) and large ball prefix (1) is fixing, and smear large ball prefix (1) and little spherical crown (2) inside edge with glue; Little spherical crown (2) and large ball prefix (1) edge retightened recover the external sight of protocorm together, again with being with the look oil pen to spread upon on the zone, little spherical crown (2) top (4) to be different from large ball prefix (1).
Claims (1)
1. 180 balls of spending are stood up in a rotation, are made of large ball prefix (1), little spherical crown (2) and filling material (3), it is characterized in that a hollow ball is cut into large ball prefix (1) and little spherical crown (2) at 2/3 to 4/5 place of diameter; With the interior space segment of large ball prefix (1) or all put completely soft filling material (3), with liquid glue that filling material (3) and large ball prefix (1) is fixing, and smear large ball prefix (1) and little spherical crown (2) inside edge with glue; Little spherical crown (2) and large ball prefix (1) edge retightened recover the external sight of protocorm together, again with being with the look oil pen to spread upon on the zone, little spherical crown (2) top (4) to be different from large ball prefix (1).
