Abstract
The utility model relates to a balancing device for a lottery turntable. The balancing device is positioned on the back side of the lottery turntable, and comprises magnetic metal strips and magnets; the magnetic metal strips are fixedly connected on the back side of the lottery turntable; the magnets are adsorbed on the magnetic metal strips under the magnetic force, and can move on the magnetic metal strips. The magnetic metal strips are arranged on the back side of the lottery turntable, then the magnets are adsorbed on the lottery turntable, and the gravity center of the whole lottery turntable is adjusted through different weights, quantities and positions of magnets, so that the lottery turntable is matched with a rotating shaft, and the gravity center is coincided with the axis, which can enable the lottery turntable to be uniform in number rocking, and enable rocked possibilities of all numbers to be the same.
Description
Technical field
The utility model relates to a kind of bascule, relates in particular to a kind of bascule of lot cast rotating disk.
Background technology
The lot cast rotating disk is a kind of very common marketing methods and apparatus for entertainment, and the probability that its each position is shaken should be the same, but because material is inhomogeneous, the coarse for example centralized positioning of manufacture craft is inaccurate, punching deviates, and circle of contact arc is round, in transportation, occurs falling, pushes and cause the center of gravity deviation.The lot cast rotating disk is normally circular, there is the center of circle middle part, the material of lot cast rotating disk is generally the materials such as PVC, Ya Like, three-ply board, the center of lot cast rotating disk is exactly the center of lot cast rotating disk geometry, the lot cast rotating disk also has center of gravity, in the middle of the lot cast rotating disk, generally be connected with rotating shaft, the lot cast rotating disk rotates around rotating shaft, and the position of axle is axle center.In the ideal case, these four hearts should overlap, but in fact often depart from.In actual use, even in order to guarantee lot cast, guarantee that each probability that will occur is the same, will accomplish four hearts coincidences as far as possible of lot cast rotating disk, especially center of gravity and axle center must overlap.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of bascule of lot cast rotating disk, solves deficiency of the prior art, can adjust the center of gravity of lot cast rotating disk, makes the axis coinciding of center of gravity and lot cast rotating disk.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of bascule of lot cast rotating disk, the bascule of described lot cast rotating disk is positioned at the back side of lot cast rotating disk, comprise magnetic metal bar and magnet, described magnetic metal bar is fixedly connected on the back side of lot cast rotating disk, described magnet can rely on magnetic-adsorption on the magnetic metal bar, and can on the magnetic metal bar, move.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described magnetic metal bar has four, and on the same diameter that wherein two are positioned at the lot cast rotating disk back side, and symmetrical mutually with respect to the center of circle, two other is positioned on the different string at the lot cast rotating disk back side, and with before two be respectively 90 ° of angles.
Further, to be fixedly attached to the mode at the lot cast rotating disk back side be that sticking double faced adhesive tape, glue stickup, riveted joint or bolt are fixed to described magnetic metal bar.
Further, described magnetic metal bar is made by iron or ferroalloy.
The beneficial effect that adopts above-mentioned further scheme is to use iron or ferroalloy to make the magnetic metal bar, and namely having magnetic can be drawn materials conveniently simultaneously by magnet adsorption, and cost is low.
The magnet used in the utility model, size, quantity and weight all can be multiple, to adapt to different lot cast rotating disk sizes and the demand of weight, uses extensively, convenient.
The beneficial effects of the utility model are: at the lot cast rotating disk back side, the magnetic metal bar is set, again magnet adsorption is got on, the center of gravity of utilizing the different weight of magnet, quantity and position to regulate whole lot cast rotating disk, make it to adapt with rotating shaft, center of gravity and axis coinciding, so just can make the lot cast of lot cast rotating disk even, the probability that each will be occurred is the same.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In accompanying drawing, the list of parts of each label representative is as follows:
1, lot cast rotating disk, 2, rotating shaft, 3, the magnetic metal bar, 4, magnet.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only be used to explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of bascule of lot cast rotating disk, the bascule of described lot cast rotating disk is positioned at the back side of lot cast rotating disk 1, comprise magnetic metal bar 3 and magnet 4, described magnetic metal bar 3 is fixedly connected on the back side of lot cast rotating disk 1, described magnet 4 can rely on magnetic-adsorption on magnetic metal bar 3, and can on magnetic metal bar 3, move.
Described magnetic metal bar 3 has four, and on the same diameter that wherein two are positioned at lot cast rotating disk 1 back side, and symmetrical mutually with respect to the center of circle, two other is positioned on the different string at lot cast rotating disk 1 back side, and with before two be respectively 90 ° of angles.
The mode that described magnetic metal bar 3 is fixedly attached to lot cast rotating disk 1 back side is that sticking double faced adhesive tape, glue stickup, riveted joint or bolt are fixed.Wherein adopting the fixing mode of bolt is the most easily, and long service life, more firm.
Described magnetic metal bar 3 is made by iron or ferroalloy.Use iron or ferroalloy to make magnetic metal bar 3, namely having magnetic can be drawn materials conveniently simultaneously by magnet adsorption, and cost is low.
The magnet 4 used in the utility model, size, quantity and weight all can be multiple, to adapt to different lot cast rotating disk 1 sizes and the demand of weight, uses extensively, convenient.
At lot cast rotating disk 1 back side, magnetic metal bar 3 is set, again magnet 4 absorption are got on, the center of gravity of utilizing the different weight of magnet 4, quantity and position to regulate whole lot cast rotating disk 1, make it to adapt with rotating shaft 2, center of gravity and axis coinciding, so just can make 1 lot cast of lot cast rotating disk even, the probability that each will be occurred is the same.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
