Description
Technical field
The utility model relates to toy for children, specifically is the device that a kind of children play husky usefulness.
Background technology
" play husky " activity is the ludic activity that each children very likes, and also is a kind of activity of developing creativity, it have start with beat one's brains combine, social science knowledge combines with natural science knowledge, science and the artistic characteristics that combine.Commonplace object for appreciation sand all is to utilize mould of plastics to make certain moulding in sand mostly at present; It is comparatively single to play husky mode; In playing husky activity, experience, let children can experience flowing of sand intuitively and observe sand fall behind the motion process that drives balance down layer by layer, the husky weight of impression in object for appreciation in order to bring the more Science Explorations of children; Understand the basic principle of lever, balance, balance, this problem does not have comparatively ideal solution so far.
Summary of the invention
The purpose of the utility model provides a kind ofly can experience flowing and observe sand and falling behind down layer by layer and drive the balance motion process of sand in object for appreciation, the weight that impression is husky, and the children that understand the basic principle of lever, balance, balance play sand and use device.
The technical scheme that the utility model adopted is:
A kind of children play the balance drift sand device of husky usefulness; 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, and middle riser is provided with upper lever; Swing in the lever hole that upper lever can be provided with on middle riser; Below the upper lever, be respectively arranged with a left side lever and bottom right lever down on left side vertical plate and the right side riser, left side lever and bottom right lever down can be swung in the lever hole of setting respectively on left side vertical plate and right side riser, the length of upper lever is greater than the distance between lever under the left side and the bottom right lever.
The upper end of body is a top board, is respectively arranged with husky hole of filling, a left side and the husky hole of right filling on the top board, and husky hole of filling, a left side and right centre bore distance of irritating between the husky hole are not more than the length of upper lever.
In riser be provided with at least two upper levers, below the every upper lever, be respectively arranged with lever and bottom right lever under the left side on left side vertical plate and the right side riser.
The lower end of body is provided with container.
Upper lever is a concave arc shape with the cross sectional shape of left lever down and bottom right lever.
Lever is provided with pin in the hole, and lever and bottom right lever and lever hole are respectively through pin and middle riser and left side vertical plate and the flexible connection of right side riser under a upper lever and the left side.
Beneficial effect: the utility model pours into sand from the filling Sha Kongzhong on the top board of the circular arc of body top, because the weight of sand makes lever tilt, falls behind the swing process that drives lever layer by layer down thereby observe sand; Make children experience husky weight intuitively; In object for appreciation, know from experience the notion of lever, balance, balance, further understand basic principle, the origin of balance, the EQUILIBRIUM CONDITION of lever, stretch into step by step; All linked with one another; Make children with the mutual use of instrument, material in, learnt knowledge, in object for appreciation, improved the profound interest of the science of trying to explore.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the side view of Fig. 1.
Among the figure: husky hole is irritated on 1A-left side, husky hole, 2-upper lever, 3A-left side 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 are down irritated in 1B-right side.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further.
A kind of children play the balance drift sand device of husky usefulness; Comprise body 9; Body 9 comprises the left side vertical plate 6 and right side riser 4 that is arranged on both sides, and the middle riser 5 in the middle of being arranged on, and middle riser 5 is provided with upper lever 2; Swing in the lever hole 7 that upper lever 2 can be provided with on middle riser 5; Below the upper lever 2, be respectively arranged with a left side lever 3A and bottom right lever 3B down on left side vertical plate 6 and the right side riser 4, left side lever 3A and bottom right lever 3B down can be swung in the lever hole 7 of setting respectively on left side vertical plate 6 and right side riser 4, the length of upper lever 2 is greater than the distance between lever 3A under the left side and the bottom right lever 3B.
The upper end of body 9 is a top board 10, is respectively arranged with husky hole 1A of left side filling and the husky hole 1B of right filling on the top board 10, and a left side husky hole 1A of filling and right centre bore distance of irritating between the husky hole 1B are not more than the length of upper lever 2.In riser 5 be provided with at least two upper levers 2, below the every upper lever 2, be respectively arranged with lever 3A and bottom right lever 3B under the left side on left side vertical plate 6 and the right side riser 4.
