Abstract
The utility model discloses a kind of magnetic suspension demonstration shelf, comprise pedestal and suspension, be provided with accommodating cavity in described pedestal, suspension is placed in this accommodating cavity, is provided with coil in base bottom, is provided with magnet in bottom suspension, and pedestal is provided with power interface; Pedestal energising after-current, by producing eddy current during coil, produces with the magnet in suspension and interacts, and makes suspension be subject to an electromagnetic force contrary with gravity direction, makes suspension unsettled.The eddy current that the utility model utilizes electromagnetic field to produce in metal surface realizes the suspension to suspension, easy to operate, suspending stabilized.
Description
Technical field
the utility model relates to a kind of showing stand, specifically a kind of magnetic suspension demonstration shelf.
Background technology
magnetic is utilized mode unsettled for suspension to be used in a lot of occasion, as the tellurion used as teaching.Logical this kind magnetically globe, primarily of spheroid, ball-collecting rack, South Pole magnet, iron sheet spherical shell and North magnet composition, the South Pole of tellurion and the arctic install one block of magnet respectively, can signal magnetic field in analog, fixed magnet marker, makes tellurion be subject to magnetic force and unsettled, carries out teaching and uses.In other occasions, as market or exhibition place, part businessman adopts mechanical show apparature to carry out exhibiting product, and this type of mechanical show apparature bandwagon effect is comparatively fixing, interesting poor.Had a kind of maglev showing stand at present, the upper and lower side of suspension produces different magnetic to have suspended object by the iron core after permanent magnet and energising.This kind of product is more loaded down with trivial details in the middle of implementation process, and it must have permanent magnet and iron core to be just achieved up and down, repels each other below, being difficult to find central point, being easy to allow product depart from equalization point when carrying out reconciliation of inventory location due to attracting above.Moreover need all will be energized up and down, so linking up up and down, all many-sided restrictions must be subject to when carrying out exhibiting product design.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of magnetic suspension demonstration shelf, easy to operate, suspending stabilized.
In order to solve the problems of the technologies described above, the utility model takes following technical scheme:
A kind of magnetic suspension demonstration shelf, comprise pedestal and suspension, be provided with accommodating cavity in described pedestal, suspension is placed in this accommodating cavity, is provided with coil in base bottom, is provided with magnet in bottom suspension, and pedestal is provided with power interface; Pedestal energising after-current, by producing eddy current during coil, produces with the magnet in suspension and interacts, and makes suspension be subject to an electromagnetic force contrary with gravity direction, makes suspension unsettled.
The described electric current passing into coil is alternating current, and the frequency of this alternating current is 104 ~ 105Hz, and the quality of suspension is within 600 grams.
Described pedestal is in " C " word shape.
Be provided with bracing frame in described base bottom, coil is contained in this support frame end.
Also illuminating source is provided with in described pedestal.
Described pedestal adopts acrylic material and stainless steel material to make.
The utility model is easy to operate, only needs bottom suspension, arrange a magnet, utilizes the magnet of the electromagnetic force of base bottom and suspension interior bottom portion to produce mutual repulsive force, make suspension unsettled, suspending stabilized.
Accompanying drawing explanation
Fig. 1 is the utility model perspective view;
Fig. 2 is the utility model decomposing state structural representation.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the utility model will be further described.
As illustrated in fig. 1 and 2, a kind of magnetic suspension demonstration shelf, comprises pedestal 1 and suspension 2, be provided with accommodating cavity 3 in described pedestal 1, suspension 2 is placed in this accommodating cavity 3, is provided with coil 4 in bottom pedestal 1, be provided with magnet in bottom suspension 2, pedestal 1 is provided with power interface; Pedestal energising after-current is by producing eddy current during coil, produce with the magnet in suspension and interact, suspension is made to be subject to an electromagnetic force contrary with gravity direction, this electromagnetic force is adjusted to equal with the gravity of suspension, the downward gravity of suspension can be offset, suspension is in one without the poised state of friction, contactless suspension, makes suspension unsettled.Pedestal is in the moulding of " C " word, and accommodating cavity is positioned at middle empty cavity position.After pedestal is connected with the mains by attaching plug, usual access be 220V alternating current, the frequency of this alternating current is 104 ~ 105Hz, the quality control of suspension within 600 grams with, it is too large that such suspension can not do, and entirety is suitable for showing comparatively light and handy product.Pedestal adopts acrylic material and stainless steel material to make, not fragile, and comparatively light and handy.
Be provided with bracing frame 5 in bottom pedestal 1, coil 4 is contained in this bracing frame 5 end, ensures the stability of coil.
In addition, be also provided with illuminating source in pedestal, after connecting with the mains, this illuminating source can send light, and light source can select all kinds of model style as required, increases the interest of product.
After the utility model is connected with the mains, high-frequency vortex is produced during high frequency electric flowing through coil, because coil is positioned at the below of accommodating cavity, therefore, after suspension is placed on accommodating cavity, the magnet of suspension interior bottom portion and the eddy current of generation produce and interact, under the preparation of suitable space, the direction of electromagnetic force can be made contrary with suspension gravity direction, make electromagnetic force equal with gravity by the power changing high frequency source, thus offset the strategy of suspension, can electromagnetic suspension be realized.
It should be noted that, the above is not the restriction to technical solutions of the utility model, and under the prerequisite not departing from creation design of the present utility model, any apparent replacement is all within protection domain of the present utility model.
