Abstract

The utility model discloses a top which is composed of a rotator 1 and a motive power traction mechanism. A shaft rod 2 stands on the rotator, the bottom end of the shaft rod is connected with the rotator in a rolling mode through a bearing 3, and the other end of the shaft rod forms a handle 4. Rotation swing frames 5 rotating around the shaft rod 2 as axis are arranged on the shaft rod and the rotator. The rotation swing frames are provided with three gravity loading blocks 6 which are in 120-degree arrangement around and outside the rotation shaft rod. The top is simple and compact in structure, the whole top is of a relative-movable structure, different patterns are showed between spinning top and non-spinning top, the top is novel to people, and thus people can be interested in the top for a long time. The top is attached with a lot of scientific knowledge, so the relationship among inertia, arm of force, moment of force, and rotation is easy to understand.

Description

A kind of gyro

Affiliated technical field

The utility model relates to the toy field, is specifically related to a kind of new spinning top.

Background technology

Existing most gyro is made of rotating main body and rotating shaft.Give rotating main body certain power, just can make teetotum be given to the people and bring certain enjoyment.But because occupation mode is single, it is permanent that interest is not easy to keep.So in design afterwards, people have injected some different elements.For example electric, sound, light etc.But do not escape from traditional occupation mode all the time, too many variation does not take place in the main body thing, has no idea to make our interest to keep permanent yet.

The utility model content

In view of the above-mentioned deficiency of prior art, the purpose of this utility model is on the basis of traditional gyro, increases more the principles of science, and the main body thing is changed in rotary course, thus the interest that stimulates us to play.

The purpose of this utility model is to realize by following means.

A kind of gyro is made up of rotary body 1 and power traction mechanism, it is characterized in that, an axostylus axostyle 2 stands on the rotary body, and its bottom connects by being on bearing and the rotary body to roll, its other end formation handle 4; One is that the rotation whipping framework 5 of center of rotation is arranged on axostylus axostyle and the rotary body with axostylus axostyle 2; Described rotation whipping framework has to be centered around and revolves axis bar and be three gravity loading blocks 6 that 120 degree distribute outward, and loading blocks has last extensible arm 7 and following extensible arm 8, and last extensible arm 7 is socketed on the axostylus axostyle by coupling ring 9, and following extensible arm is connected on the rotary body upper end; Axostylus axostyle between described coupling ring and bearing is provided with elastic recovery mechanism; Power traction is configured to be arranged on the traction groove 10 that revolves the axis bar bottom.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Can see that in conjunction with Fig. 1 to Fig. 3 the utility model gyro is made up of rotary body 1 and power traction mechanism.One axostylus axostyle 2 stands on the rotary body 1, and its bottom is to roll by bearing 3 and rotary body and connects, and its other end constitutes handle 4.One is that the rotation whipping framework 5 of center of rotation is arranged on axostylus axostyle and the rotary body with axostylus axostyle 2.Rotation whipping framework has to be centered around and revolves axis bar and be three gravity loading blocks 6 that 120 degree distribute outward, and loading blocks has last extensible arm 7 and following extensible arm 8, and last extensible arm 7 is socketed on the axostylus axostyle 2 by coupling ring 9, and following extensible arm 8 is connected on the rotary body upper end; The axostylus axostyle that described coupling ring 9 and bearing are 3 is provided with elastic recovery mechanism, is spring 11 at this, and power traction is configured to be arranged on the traction groove 10 that revolves the axis bar bottom.

Axostylus axostyle 2 is to roll by bearing and rotary body and connects, and used bearing can be used common rolling bearing, but the also coupling arrangement of use side spherical bearing or other rolling (or slip), and its concrete structure presents different modes with the bearing of selecting for use.Fig. 5 is to use the situation of rolling swivel bearing 31: following extensible arm 8 is connected on the chuck 12 mutually, and axostylus axostyle 2 connects firmly in the endoporus of swivel bearing 31, and chuck 12 is connected by interior assembling dish 13 usefulness screws and rotary body 1, like this, guarantees that axostylus axostyle 2 can rotate freely.

Play when using, one holds handle 4, the another hand use pull rope 14 be wound in traction grooved 10 the insides a few, pull out with strength then.Because action of inertia, strong rotation can take place in gyro.Because action of inertia is rotated the support arm expansion downwards that gravity loads on the whipping framework, as the variation among Fig. 4, gravity adds the end that object carrier can slide to support arm automatically, follows rotation simultaneously.When the rotating speed reduction of gyro, because the change of the arm of force, gravity adds object carrier and can slide to rotating shaft, keeps comparatively faster rotating speed thereby keep gyro.

The advantage of the utility model utility model and good effect can be summarized as following some:

1) simple in structure, compact.

2) whole gyro is a movable relatively structure, rotation with do not rotate between present different patterns, make the people feel novel, thus maintenance long period interest.

3) added a lot of scientific knowledges, made the straightaway relation of understanding inertia, the arm of force, moment and rotation of people.
