Description

The tumbler of adjustable balance weight

The utility model relates to a kind of tumbler of adjustable balance weight, belongs to the technical field of teaching aid and toy for children.

The product of tumbler is a lot, but all is one-piece construction, can not put adjustable counterweight in the inner chamber, therefore as teaching aid, can't make the student thoroughly understand the principle that tumbler does not fall, and existing tumbler moulding is simpler and cruder.

The purpose of this utility model is the tumbler that a kind of adjustable balance weight will be provided, and it can overcome above-mentioned deficiency, and the tumbler inner chamber has the counterweight of adjustable positions, center of gravity is changed, can make the student be more readily understood the principle of tumbler, be suitable for use as teaching aid, also can be used as toy for children.

The purpose of this utility model is achieved in that

A kind of tumbler of adjustable balance weight, its top cone (1) is combined into one with base (2), and plasticine (5) places in the base (2), and base (2) is a semisphere, and nose (4) is arranged at its top, and annular arrowband (3) is arranged at the bottom of top cone (1) inwall.

The tumbler synoptic diagram of Fig. 1 adjustable balance weight;

Fig. 2 user mode synoptic diagram.

Now in conjunction with the accompanying drawings the structure of the tumbler of adjustable balance weight is described in detail.

By Fig. 1, tumbler is by top cone (1) and hemispheric base (2), there is an annular arrowband (3) top cone (1) inner chamber middle and lower part, base (2) is a hollow hemisphere, nose (4) is arranged at its top, and top cone (1) and base be chimeric being integral mutually, and arrowband (3) just in time contact with nose (4), with viscosity preferably plasticine (5) place in the base (2), promptly form the tumbler of an adjustable balance weight.

By Fig. 2, when if plasticine (5) places base (2) middle position, tumbler can be kept and stablely and unlikely topple over, if plasticine (5) is placed when taking back the position, tumbler just can only be when dotted line position balance, utilize the changing position of plasticine (5), can make the student thoroughly understand the unlikely principle of toppling over of tumbler.

Compared with prior art, the adjustable tumbler of counterweight has following advantages:

1, top cone and base combination with separate all extremely convenient;

2, cone and base are all used plastic production, and any surface finish is bright-colored;

3, plasticine is soft, is easy to press displacement with fingers with finger;

4, be suitable for as teaching aid;

5, volume is little, is easy to carry;

6, adopt split type structure, be easy to make.

Claims

1, a kind of tumbler of adjustable balance weight, it is characterized in that top cone (1) and base (2) are combined into one, plasticine (5) places in the base (2), and base (2) is a semisphere, nose (4) is arranged at its top, and annular arrowband (3) is arranged at the bottom of top cone (1) inwall.
