Abstract
The utility model provides a probability teaching tool for university teaching and relates to the field of teaching aid tools. The probability teaching tool for university teaching is composed of a rectangular frame, cylinder modules and a hook. More than one longitudinal separation board is installed in the rectangular frame for dividing the rectangular frame longitudinally uniformly into three parts or above. Two ends of the separation boards are fixed on the upper end and the lower end of the rectangular frame. Fixing shafts are installed between the adjacent longitudinal separation boards. Two ends of the fixing shafts are fixed on the upper end and the lower end of the rectangular frame. Centers of more than one cylinder module are threaded on the fixed shaft axially. Transverse separation boards are arranged between two adjacent cylinder modules on the same fixed shaft. And the fixed shaft penetrates through the transverse separation board. Two ends of the transverse separation boards are fixed on the left frame and the right frame of the rectangular frame and the separation boards are clamped with the longitudinal separation boards. More than two colors are arranged on the surfaces of the cylinder modules longitudinally in average. According to the utility model, the adjacent cylinders can be in different colors, so that the demonstration can be direct and clear and convenience is made for students to understand and learning Probability. The probability teaching tool for university teaching has characteristics that the probability teaching tool for university teaching is striking and easy to operate when being used for demonstrating, so that convenience is made for students to understand and learning Probability.
Description
Technical field
The utility model relates to teaching appurtenance field, relates in particular to a kind of Teaching in University probability teaching aid.
Background technology
Probability is the comparison abstract concept, in big immunologing mathematics theory of probability course, if can cooperate explanation by the demonstration of probability teaching aid, can make the student be more readily understood and grasp.And up to now, because not being fit to the probability teaching aid of teaching usefulness, the student can only explain by the teacher and understand probability theory, this mode student who gives lessons is not high to understanding and the grasp degree of probability, teaching is painstaking the process of explaining also ten minutes, is badly in need of a kind of teaching and cooperates teaching with the probability teaching aid.
Summary of the invention
Of the present utility modelly be intended at the deficiency that exists in the background technology, and a kind of Teaching in University probability teaching aid that provides.
A kind of Teaching in University of the utility model probability teaching aid, be by rectangular frame, right cylinder module and link constitute, more than one longitudinal baffle is installed with rectangular frame vertically more than average two five equilibriums in rectangular frame inside, the two ends of longitudinal baffle are fixed on the two ends up and down of rectangular frame, between two adjacent longitudinal baffles stationary shaft is installed all, the two ends of stationary shaft are fixed on the two ends up and down of rectangular frame, on stationary shaft, axially wear the center of more than one right cylinder module, be provided with lateral partitions between adjacent two right cylinder modules on the same stationary shaft, and stationary shaft passes lateral partitions, the lateral partitions two ends be fixed on the right and left frame of rectangular frame and with the longitudinal baffle clamping, vertically on average be provided with two or more colors on the right cylinder module surface.
As further improvement of the utility model, the diameter of right cylinder module is greater than the air line distance between two adjacent longitudinal baffles.
As further improvement of the utility model, the specification of all right cylinder modules is identical.
As further improvement of the utility model, the rectangular frame top is provided with more than one link.
A kind of Teaching in University of the utility model probability teaching aid, the structural design novelty, be provided with several stationary shaft at rectangular frame, can express the demonstration of probability intuitively, and adjacent demonstration cylinder can be selected different colors for use, demonstrates more intuitively, more eye-catching, is beneficial to that the student understands and this subject of study probability, when demonstration, have eye-catching, easy-operating characteristics, be convenient to student's understanding and this subject of study probability.
Description of drawings
Fig. 1 is one-piece construction front view of the present utility model;
Fig. 2 is the partial enlarged drawing of adjacent two right cylinder modules on the same stationary shaft of the utility model.
Embodiment
Below in conjunction with 1 pair of a kind of Teaching in University of the utility model of accompanying drawing probability teaching aid, be described further;
A kind of Teaching in University probability teaching aid of the present utility model is to be made of rectangular frame 1, right cylinder module 2 and link 3, is provided with more than one link 3 at rectangular frame 1 top, conveniently carries and puts.It is vertical more than average two five equilibriums with rectangular frame 1 that more than one longitudinal baffle 4 is installed in rectangular frame 1 inside, the two ends of longitudinal baffle 4 are fixed on the two ends up and down of rectangular frame 1, between two adjacent longitudinal baffles 4 stationary shaft 5 is installed all, the two ends of stationary shaft 5 are fixed on the two ends up and down of rectangular frame 1, axially wearing the center of the identical right cylinder module 2 of above specification on stationary shaft 5, its right cylinder module 2 can be that bearing is connected with stationary shaft 5.Be provided with lateral partitions 6 between adjacent two right cylinder modules 2 on the same stationary shaft 5 and stationary shaft 5 passes lateral partitions 6, lateral partitions 6 two ends be fixed on the right and left frame of rectangular frame 1 and with longitudinal baffle 4 clampings, right cylinder module 2 surfaces are gone up and vertically on average are provided with two or more colors, and the diameter of right cylinder module 2 is greater than the air line distance between two adjacent longitudinal baffles.
Utilize link 3 that it is hung on the wall the utility model during use, rotate several right cylinder modules 2 on each stationary shaft 5, the right cylinder module 2 on two adjacent stationary shaft 5 can be selected different colors for use.
