Description
Technical field
This utility model relates to statistics teaching appurtenance technical field, is specifically related to a kind of statistics probabilistic model teaching aid.
Background technology
Probability is to compare abstract concept, in statistics probability course, if explanation can be coordinated by the demonstration of probability teaching aid, student can be made to be easier to understand and grasp.And at present, because being suitable for the probability teaching aid of teaching, student can only explain by teacher and understand probability theory, and this mode given lessons makes student that understanding and the Grasping level of probability is not high, teacher's also very painstaking in the process explained.Therefore, it is badly in need of a kind of teaching probability teaching aid to carry out coordinating teaching.
Utility model content
Technical problem to be solved in the utility model is to provide the statistics probabilistic model teaching aid of a kind of simple in construction, easy to operate, good demonstration effect.
For solving above-mentioned technical problem, this utility model provides techniques below scheme: a kind of statistics probabilistic model teaching aid, including plate body, display channel, telescopic chute, the slider bar corresponding with telescopic chute, the front of described plate body uniformly offers the display channel of several genesis analysis, the end face of described plate body offers the telescopic chute of the genesis analysis corresponding with each display channel, described display channel is connected with telescopic chute, the width of described telescopic chute is more than the width of display channel, described slider bar slides up and down and is placed in telescopic chute, the interior back side of described telescopic chute is provided with instruction colour code；It is characterized in that: also include the suspension arrangement for hanging slider bar, described suspension arrangement includes the link being fixed on slider bar end face, with externally threaded column, moving sleeve, L-type connecting rod, link up with and be with female abutment sleeve, the top of described plate body is provided with top board, the top of described column is fixedly connected on top board, what described moving sleeve moved up and down is enclosed within column, described abutment sleeve is positioned at moving sleeve bottom and is threadedly connected on column, described hook is fixed at the bottom of L-type connecting rod, described link is connected on moving sleeve by hook and L-type connecting rod.
On such scheme basis preferentially, also including base, described plate body is fixed on base, is connected fixing between described top board and base by the support bar of both sides.
On such scheme basis preferentially, the side in the front of described plate body is provided with the graduation mark of genesis analysis.
This utility model compared with prior art has the beneficial effect that this utility model utilizes suspension arrangement to regulate slider bar suspension height, when slider bar rises in telescopic chute, instruction colour code in telescopic chute will pass through display channel and shows, can intuitively express the demonstration of probability, and adjacent display channel can select the instruction colour code of different colours, demonstration more intuitively, more eye-catching, be beneficial to student understand and this subject of learning probability, demonstration time there is feature eye-catching, easy-operating.
