Problems solved by technology
[0003] In the teaching of econometrics and statistics in econometrics, it is often necessary to use multimedia teaching devices for econometrics and statistics required for teaching, but traditional multimedia teaching devices are used for a long time, because there is no heat dissipation structure inside, and only rely on the natural heat dissipation of air holes , the heat generation is serious, and most of the teaching devices are external, long-term use, the internal dust pollution is serious, affecting the normal service life of the equipment, so we propose a multimedia teaching device based on measurement and statistics to solve the above problems

Embodiment Construction
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0024] refer to Figure 1-7 , a multimedia teaching device based on measurement and statistics, comprising a housing 1, the side wall of the housing 1 is provided with an installation groove, a touch screen 2 is fixedly installed in the installation groove, and a partition 3 is fixedly connected to the inner wall of the housing 1, The partition 3 is made of insulating material or treated with an insulating painting process, so that the partition 3 cannot conduct static electricity, thereby preventing static electricity from affecting related electronic components inside the housing 1;
[0025] The side wall of the partition 3 is provided with a plurality of through h...

The invention discloses a multimedia teaching device based on measurement statistics, relates to the field of teaching equipment, including a shell, a mounting groove is formed in the side wall of theshell in a penetrating manner; a touch screen is fixedly mounted in the mounting groove; a partition plate is fixedly connected to the inner side wall of the shell. A plurality of through holes are formed in the side wall of the partition plate in a penetrating mode. A driving motor is fixedly mounted on the side wall of the partition plate; the driving motor and the fan blades are matched for use; the driving motor drives the fan blades to rotate; air in the shell circularly flows; heat generated by a touch screen and related electronic elements in the shell is brought out from the interiorof the shell; and meanwhile, when a driving motor operates, a rotary drum and a rubber rod are synchronously driven to rub to generate static electricity, dust, entering the shell, in air is adsorbedthrough the static electricity, the situation that the internal structure of equipment is affected due to the fact that the dust is accumulated in the shell is avoided, and then the normal service life of the equipment is guaranteed.
Description
technical field [0001] The invention relates to the field of teaching equipment, in particular to a multimedia teaching device based on metering and statistics. Background technique [0002] Econometrics is a subject that combines economic theory and mathematical statistics, and uses actual economic data for quantitative analysis. The main content includes theoretical econometrics and applied econometrics. Theoretical econometrics mainly studies how to use, transform and develop The method of mathematical statistics makes it a special method for the determination of stochastic economic relations. Applied econometrics is under the guidance of certain economic theories and based on statistical data reflecting facts, using econometric methods to study the practical application of economic mathematical models Or explore empirical economic laws; [0003] In the teaching of econometrics and statistics in econometrics, it is often necessary to use multimedia teaching devices for e...
