Abstract

The utility model relates to a nested top composed of a central top and an outer covered top. The outer covered top is provided with a hollow groove which is opened upward, and the central top is higher than the hollow groove; the outer circumferential of the nested top is provided with a plurality of tooth grooves which are parallel to an axis of the nested top. When the nested top rotates at high speed, the central top can jump out of the outer covered top to rotate automatically after landing ground, which increases the interesting of the nested top.

Description

The telescopiform gyro

The utility model relates to the gyro of whipping rotation, particularly a kind of telescopiform gyro.

Have in the existing gyro and a kind ofly make the gyro reinforcing with the gyro whip, the gyro that it is ceaselessly rotated, it is shaped as bottom cylinder spherical in shape, be embedded with a steel ball at the center of spherical, with ball as pivot point, the one, be the frictional force of minimizing gyro to ground, the 2nd, wear-resisting durable in order to make gyro.Traditional gyro generally is wooden solid, though can make it attractive in appearance lovely at the various color fringe patterns of surface rendering, exists the pattern shape single, the shortcoming of playing method dullness.The existing gyro of whipping is considered and friction when lashing is all adopted timber Xuan system, formulates as adopting macromolecular material and metal, and because of friction is little, poor effect.

The purpose of this utility model provides a kind of telescopiform gyro, in the diabolo of a upper opening, put into a less center gyro, when the gyro fast rotational, because the rotating speed difference of inside and outside gyro, the center gyro can be by jumping out in the diabolo, rotation automatically after landing.Increase the variety of gyro like this, increase the interest of toy, this telescopiform gyro can still have good result of use with macromolecular material or light metal manufacturing in addition.

For achieving the above object, the utility model is taked following design: it is made of center gyro and overcoat gyro, and center gyro shape is with to whip gyro identical; The overcoat gyro is provided with the groove of a upward opening, and the groove internal diameter is slightly larger than center gyro external diameter, and bottom land is a hemispherical, and the degree of depth of groove is less than the height of center gyro; Uniform one 10 teeth groove parallel on the cylindrical of center gyro and overcoat gyro with its axis.

The utility model provides a kind of novelty interesting Entertainment toy gyroscope, in use the center gyro is placed in the groove of overcoat gyro.Because center gyro height is greater than the groove degree of depth, gyro upper end in center is higher than overcoat gyro upper end, and the center gyro is exposed to outside the overcoat gyro one section, is convenient to it is taken out groove; The groove bottom land is a hemispherical simultaneously, and gyro bottom in center also is hemispherical, but the gyro bottom is provided with ball routinely, ball contact overcoat gyro groove bottom land is only arranged, make gyro bottom, center and groove bottom that more abundant gap be arranged, not only reduce the friction of the two, and can prevent that the two from attaching rear center's gyro mutually and being difficult for deviating from the groove.Make it fall within ground after rotating the overcoat gyro by hand, make the overcoat gyro with the gyro whip again, accelerate its rotary speed, the center gyro simultaneously by induced effect to rotation.But because the two has abundant gap, frictional force is less when overcoat rotates at a high speed, and the center gyro of passive rotation can be gone in the groove to jump out by sky, and falls within rotation voluntarily on the ground.Available whip was made two gyros and was rotated simultaneously this moment, also can be placed in the overcoat gyro after little gyro stall, after the overcoat gyro quickens rotation, the center gyro was jumped out once more.Like this, the utility model has increased the variety of toy gyroscope, has increased the interest of toy.This telescopiform gyro can be saved timber, and use the mould manufacturing with macromolecular material or light metal material manufacturing, reduces cost.Enhance productivity, because the smooth finish surface frictional force of above-mentioned material is little, the effect of rotation is whipped in influence.The utility model is uniform a plurality of teeth groove on the gyro cylindrical, lash the effect of rotation with improvement, and an above-mentioned difficult problem is resolved.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 2 is a multilayer telescopiform gyro cut-away view

Fig. 3 is the Sound-emitting top structural representation

As shown in Figure 1, this telescopiform gyro is made of center gyro 1 and overcoat gyro 3, and the center gyro is with to whip gyro identical; The overcoat gyro is provided with the groove 2 of a upward opening, and groove is slightly larger than center gyro external diameter, and bottom land is a hemispherical, the degree of depth of groove, and less than the height of center gyro, the gyro bottom is embedded with

ball

4,5; The uniform 3-10 bar teeth groove 6,7 parallel on the gyro cylindrical with its axis.In order further to improve the interest of this gyro, the groove and the overcoat gyro in it that can add the second overcoat gyro, 8, the second overcoat gyros outside magneto gyrocompass can mate, and its form as shown in Figure 2.Can also in the gyro of center, add sound-producing device, make gyro can send sound equipments such as music language firecracker sound in use, increase the atmosphere in its recreation, its structure is as shown in Figure 3: establish lid 9 on gyro top, center, lid is provided with air vent 10, and the device 11 of winnowing is installed at the air vent place, establishes electric apparatus room in the gyrostat, install battery 12, vibration switch 13 in it, acoustics circuit chip 14.
