Description
Technical field
The present invention relates to toy for children, specifically the device used of a kind of children playing with sand.
Background technology
" play husky " activity is the ludic activity that each children extremely likes, and is also a kind of activity of ﹠ Development Creative Power, it have start with beat one's brains combine, social science knowledge combines with natural science knowledge, Science and art combines characteristics.Commonplace object for appreciation sand is all to utilize mould of plastics to make certain moulding in sand mostly at present, play husky mode comparatively single, experience in order to bring the more Science Explorations of children in playing husky activity, allow children can experience intuitively flowing of sand and observe the sand lower motion process that drives balance that falls behind layer by layer, the husky weight of impression in object for appreciation, understand the ultimate principle of lever, balance, balance, this problem does not have comparatively ideal solution so far.
Summary of the invention
The purpose of this invention is to provide a kind of can experience in object for appreciation sand flow and observe sand layer by layer lower the backwardness drive the balance motion process, the weight that impression is husky is understood the children playing with sand device of the ultimate principle of lever, balance, balance.
The technical solution adopted in the present invention is:
The balance quicksand device that a kind of children playing with sand is used, comprise body, body comprises left side vertical plate and the right side riser that is arranged on both sides, and the middle riser in the middle of being arranged on, be provided with upper lever on middle riser, upper lever can arrange on middle riser lever swings in the hole, below upper lever, be respectively arranged with lower-left lever and bottom right lever on left side vertical plate and right side riser, lower-left lever and bottom right lever can be on left side vertical plate and right side riser arrange respectively lever swings in the hole, and the length of upper lever is greater than the distance between lower-left lever and bottom right lever.
The upper end of body is top board, is respectively arranged with the husky hole of left filling and right filling husky hole on top board, and the center pit between the husky hole of left filling and right filling husky hole is apart from the length that is not more than upper lever.
Be provided with at least two upper levers on middle riser, below every upper lever, be respectively arranged with lower-left lever and bottom right lever on left side vertical plate and right side riser.
The lower end of body is provided with container.
The cross sectional shape of upper lever and lower-left lever and bottom right lever is concave arc shape.
Lever is provided with pin in the hole, and upper lever and lower-left lever and bottom right lever and lever hole are flexibly connected by pin and middle riser and left side vertical plate and right side riser respectively.
beneficial effect: the present invention pours into sand from the filling Sha Kongzhong on the top board of the circular arc of body top, because making lever, the weight of sand tilts, thereby observe the sand lower swing process that drives lever that falls behind layer by layer, make children experience intuitively husky weight, know from experience lever in object for appreciation, balance, the concept of balance, further understand the ultimate principle of lever, the origin of balance, the condition of balance, stretch into step by step, all linked with one another, make children with instrument, in the mutual use of material, learnt knowledge, improved the interest of trying to explore science profoundness in object for appreciation.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the side view of Fig. 1.
In figure: 1A-left filling husky hole, 1B-right filling husky hole, 2-upper lever, 3A-lower-left lever, 3B-bottom right lever, 4-right side riser, 5-middle riser, 6-left side vertical plate, 7-lever hole, 8-pin, 9-body, 10-top board, 11-container.
Embodiment:
The invention will be further described below in conjunction with accompanying drawing.
the balance quicksand device that a kind of children playing with sand is used, comprise body 9, body 9 comprises left side vertical plate 6 and the right side riser 4 that is arranged on both sides, and the middle riser 5 in the middle of being arranged on, be provided with upper lever 2 on middle riser 5, the lever hole 7 interior swings that upper lever 2 can arrange on middle riser 5, below upper lever 2, be respectively arranged with lower-left lever 3A and bottom right lever 3B on left side vertical plate 6 and right side riser 4, the lever hole 7 interior swings that lower-left lever 3A and bottom right lever 3B can arrange respectively on left side vertical plate 6 and right side riser 4, the length of upper lever 2 is greater than the distance between lower-left lever 3A and bottom right lever 3B.
The upper end of body 9 is top board 10, is respectively arranged with the husky hole 1B of the husky hole 1A of left filling and right filling on top board 10, and the center pit between the husky hole 1B of the husky hole 1A of left filling and right filling is apart from the length that is not more than upper lever 2.Be provided with at least two upper levers 2 on middle riser 5, below every upper lever 2, be respectively arranged with lower-left lever 3A and bottom right lever 3B on left side vertical plate 6 and right side riser 4.
