Description

Random pendulum

Technical field

The utility model belongs to instructional device technical field, is specifically related to a kind of magnetic exhibiting device.

Background technology

Magnet is five common in life, two like magnetic poles repel each other, and the opposite sex is repelled each other, and as you know, in instructional device, the exhibiting device of magnet is too dull for this principle, and learner or participant lose interest in to exhibiting device, are unfavorable for displaying and the memory of magnet knowledge.

Utility model content

The technical problem existing for solving prior art, the utility model provides the exhibiting device of magnet magnetic knowledge, and bandwagon effect is good, and participant can experience the enjoyment of participation in learning knowledge.

For achieving the above object, the technical scheme that the utility model adopts is: random pendulum, comprise base, the top of base is fixed with annular bottom panel, the top of base is provided with top panel, top panel, bottom panel and base arrange with one heart, between bottom panel and top panel, pass through stent support, the bottom of top panel is fixed with pendulum, pendulum comprises stainless steel, the upper end of stainless steel is hinged on top panel, stainless steel is fixed with mallet, the bottom of mallet is fixed with main magnet by dormant bolt, the middle part of base is fixed with the centring magnet contrary with main magnet magnetic pole, in bottom panel, be provided with three limit magnet identical with main magnet magnetic pole, three change magnet are uniform around the center equal angles of bottom panel.

This device is for demonstrating the magnetic pole two like magnetic poles repel each other of permanent magnet, the characteristic that there is a natural attraction between the sexes, by the centring magnet of a permanent magnetism is installed at pendulum bottom and the base center of pressing close to pendulum bottom respectively, the magnetic pole of two kinds is that Magnetic Phase of the same name is right, the circumference equal intervals of the bottom panel that is 850mm at diameter is provided with the limit magnet of three permanent magnetism, and its magnetic pole is contrary with the main magnet magnetic pole of pendulum bottom, and polarity is relative. When being subject in the pendulum of stress balance state outside spectators after force-disturbance, due to the two like magnetic poles repel each other between magnetic pole, there is a natural attraction between the sexes effect, the pendulum swinging track showing is unpredictable, is finally parked at random on the position between a certain magnetic pole and the centring magnet on diameter 850mm circumference.

Support comprises four struts, and four struts arrange around the equal angles interval, center of top panel, and the top of four struts connects by upper annulus, and the middle part of four struts connects by middle annulus, and the bottom of four struts connects by lower annulus, and overall structure is stable.

Wherein, as preferably, mallet is cone.

Participant swings pendulum, and the movement locus of pendulum is random, and it is upper that pendulum is finally parked in one of three stress balance positions of pendulum at random, thus the intuitional and experiential thinking the interaction force between magnet magnetic pole.

This device does not need electricity consumption, and showpiece mainly configures and use material: carbon steel, stainless steel, engineering plastics, compact-panel, employing color painting environmental protection baking vanish, magnet steel etc., environmental protection.

In figure, 1 is base, and 2 is bottom panel, and 3 is top panel, and 4 is support, and 5 is pendulum, and 6 is stainless steel, and 7 is mallet, and 8 is dormant bolt, and 9 is main magnet, and 10 is strut, and 11 is upper annulus, and 12 is middle annulus, and 13 is lower annulus.

Detailed description of the invention

In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

As Figure 1-5, random pendulum, comprise base 1, the top of base 1 is fixed with annular bottom panel 2, the top of base 1 is provided with top panel 3, top panel 3, bottom panel 2 and base 1 arrange with one heart, between bottom panel 2 and top panel 3, support by support 4, the bottom of top panel 3 is fixed with pendulum 5, pendulum 5 comprises stainless steel 6, the upper end of stainless steel 6 is hinged on top panel 3, stainless steel 6 is fixed with mallet 7, the bottom of mallet 7 is fixed with main magnet 9 by dormant bolt 8, the middle part of base 1 is fixed with the centring magnet contrary with main magnet 9 magnetic poles, in bottom panel 2, be provided with three limit magnet identical with main magnet 9 magnetic poles, three change magnet are uniform around the center equal angles of bottom panel 2.

This device is for demonstrating the magnetic pole two like magnetic poles repel each other of permanent magnet, the characteristic that there is a natural attraction between the sexes, by the centring magnet of a permanent magnetism is installed at pendulum 5 bottoms and base 1 center of pressing close to pendulum 5 bottoms respectively, the magnetic pole of two kinds is that Magnetic Phase of the same name is right, the circumference equal intervals of the bottom panel 2 that is 850mm at diameter is provided with the limit magnet of three permanent magnetism, and its magnetic pole is contrary with main magnet 9 magnetic poles of pendulum 5 bottoms, and polarity is relative. When the pendulum 5 in stress balance state is subject to outside spectators after force-disturbance, due to the two like magnetic poles repel each other between magnetic pole, there is a natural attraction between the sexes effect, pendulum 5 swinging tracks that show are unpredictable, are finally parked at random on the position between a certain magnetic pole and the centring magnet on diameter 850mm circumference.

Support 4 comprises four struts 10, four struts 10 arrange around the equal angles interval, center of top panel 3, and the top of four struts 10 connects by upper annulus 11, and the middle part of four struts 10 connects by middle annulus 12, the bottom of four struts 10 connects by lower annulus 13, and overall structure is stable.

Wherein, as preferably, mallet 7 is cone.

Participant swings pendulum 5, and the movement locus of pendulum 5 is random, and it is upper that pendulum 5 is finally parked in one of three stress balance positions of pendulum 5 at random, thus the intuitional and experiential thinking the interaction force between magnet magnetic pole.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., all should wrap within the scope of the utility model.
