Abstract

The invention discloses a gyroscope, comprising a rotator 1 and a power traction mechanism, wherein a shaft rod 2 is erected on the rotator, the bottom end of the shaft rod 2 is in rolling linkage with the rotator through a bearing 3, and the other end of the shaft rod 2 constitutes a handle 4; and a rotary swinging framework 5 taking the shaft rod 2 as a rotation axis is arranged on the shaft rod and the rotator, and comprises three gravitational loading blocks 6 which are distributed around the outside of the shaft rod by 120 degrees. The gyroscope disclosed by the invention is simple and compact in structure, the entire gyroscope is a relatively moving structure and can present different patterns between rotation and non-rotation, so that the gyroscope is fantastic and people can keep interested in the gyroscope for a longer time, and in addition, much scientific knowledge is attached so as to make people understand the relationship among inertia, arm of force, torque and rotation in a popular and easy way.

Description

A kind of gyro

Affiliated technical field

The present invention relates to the toy field, be 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 all the time traditional occupation mode, too many variation does not occur in the main body thing, has no idea to make our interest to keep permanent yet.

Summary of the invention

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

The objective of the invention is to realize by following means.

A kind of gyro is comprised 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 rotation whipping framework 5 take axostylus axostyle 2 as center of rotation is arranged on axostylus axostyle and the rotary body; Described rotation whipping framework has and is centered around the spin axis rod member and is three gravitational load pieces 6 that 120 degree distribute outward, and loading blocks has upper extensible arm 7 and lower extensible arm 8, and upper extensible arm 7 is socketed on the axostylus axostyle by coupling ring 9, and lower extensible arm is connected on the rotary body upper end; Be provided with elastic recovery mechanism on the axostylus axostyle between described coupling ring and bearing; Power traction is configured to be arranged on the traction groove 10 of spin axis rod member bottom.

The specific embodiment

The invention will be further described below in conjunction with drawings and Examples.

Can see in conjunction with Fig. 1 to Fig. 3, gyro of the present invention is comprised 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 consists of handle 4.One rotation whipping framework 5 take axostylus axostyle 2 as center of rotation is arranged on axostylus axostyle and the rotary body.Rotation whipping framework has and is centered around the spin axis rod member and is three gravitational load pieces 6 that 120 degree distribute outward, and loading blocks has upper extensible arm 7 and lower extensible arm 8, and upper extensible arm 7 is socketed on the axostylus axostyle 2 by coupling ring 9, and lower extensible arm 8 is connected on the rotary body upper end; Being provided with elastic recovery mechanism on the axostylus axostyle that described coupling ring 9 and bearing are 3, is spring 11 at this, and power traction is configured to be arranged on the traction groove 10 of spin axis rod member 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.Fig. 5 is the situation of using rolling swivel bearing 31: lower 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, then pull out with strength.Because the effect of inertia, strong rotation can occur in gyro.Because of the effect of inertia, rotate the support arm expansion downwards of gravitational load on the whipping framework simultaneously, such as the variation among Fig. 4, gravitational load object meeting automatic sliding is followed rotation to the end of support arm.When the rotating speed reduction of gyro, because the change of the arm of force, the gravitational load object can slide to rotating shaft, keeps comparatively faster rotating speed thereby keep gyro.

Advantage of the present invention and good effect can be summarized as following some:

1) simple in structure, compact.

2) whole gyro is a relatively movable 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.
