Concentrate swash plate, block piece, connecting screw rod, judgement charging conduit, firm banking；The upper end of described probability demonstration box is provided with bead and entered
Mouthful, a pair of concentration swash plates are provided with the inside of bead entrance, the alternate internal of probability demonstration box is provided with several block pieces；Described
The lower end of probability demonstration box is connected with judgement charging conduit by connecting screw rod, judges that the lower end of charging conduit is connected with firm banking；
Wherein, described judgement charging conduit includes baffle plate storage tank, sliding rail, embedded roller, connecting bracket, evenly divided chi, gear
Plate；Judge that the right-hand member of charging conduit is connected with baffle plate storage tank, judge that the bottom of charging conduit is provided with sliding rail, sliding rail it is interior
Portion is provided with embedded roller, and the outside of embedded roller is connected with baffle plate by connecting bracket, and baffle plate activity is connected to judgement
The inside of charging conduit；The outer surface of described judgement charging conduit is provided with evenly divided chi.
Preferably, the inside upper and lower ends of described sliding rail are provided with damping rubber, damping rubber with it is embedded
Roller is connected with each other.
Preferably, using movable plug in construction, connection between the upper end of described connecting screw rod and probability demonstration box
Using the stationary structure that spins between the lower end of screw rod and judgement charging conduit.
When the utility model is operated, baffle plate is equally distributed on by the cooperation of embedded roller and connecting bracket sentenced first
Determine in charging conduit, be then put into ten beads from bead entrance, and random drop to is sentenced in the case where concentrating swash plate, the cooperation of block piece
Determine in charging conduit, then counted；The cooperation non-equidistantly distributed by baffle plate in embedded roller and connecting bracket is judging again
In charging conduit, bead being carried out again and is dropped demonstration, statistics bead quantity is sick to be contrasted twice, reaches the purpose of teaching demonstration
After said structure, the utility model has the beneficial effect that：A kind of new probability religion described in the utility model
Apparatus for demonstrating, it using the dividing plate of movable structure coordinate evenly divided chi will can judge charging conduit be divided into equidistantly or
Person's difference spacing two ways, can be clearly to dissect probability problem by the contrast lecture experiment of two ways so that learn
Raw easier to understand, the utility model has simple in construction, sets reasonable, the advantages of low manufacture cost.
