Abstract
The utility model discloses a biological specimen display device for teaching. The biological specimen display device comprises a base, and a motor and a speed reducer which are fixedly arranged on the base, wherein the speed reducer is provided with a main shaft which is vertically upward; the upper part of the main shaft is connected with a rotating shaft by virtue of a coupling; the top of the rotating shaft is fixedly provided with a display plate; the upper surface of the display plate is provided with a glass cover; and the display plate is provided with a shift knob used for controlling the on and off of the motor. The biological specimen display device for teaching has the following beneficial effects: (1), the structure is simple; (2) during display, multiple glass wares for containing biological specimens are placed on the display plate and covered by the glass cover; then the shift knob is turned on, the motor starts operating and drives the main shaft and the display plate to turn, and students can observe the details of the biological specimens conveniently; and (3), the shift knob is arranged on the display plate, so that the motor can be turned off at any time according to needs, and observation can be performed conveniently.
Description
Technical field
The utility model relates to a kind of bioconversion medium apparatus, particularly a kind of teaching biological sample display device.
Background technology
At present; in the teaching practice of middle school biology; in order to allow the better various biologies of understanding of students; the teacher can show multiple biological sample usually; because various biological samples are all deposited in the glassware; in order to allow students can see the details of biological sample clearly, the rotary glass vessel that the teacher has to not stop, thereby very inconvenient.
Summary of the invention
Problem to be solved in the utility model is: a kind of teaching biological sample display device simple in structure, that can rotate automatically is provided.
In order to solve the problems of the technologies described above, teaching of the present utility model biological sample display device, comprise base, be fixed on motor and speed reduction unit on the base, described speed reduction unit is provided with main shaft straight up, the top of described main shaft is connected with rotating shaft by shaft coupling, Graphic Panel is fixedly arranged at the top of described rotating shaft, places cloche on the upper surface of described Graphic Panel, and described Graphic Panel is provided with the shift knob of control motor switch.
The beneficial effect that the utility model is obtained is: (1) is simple in structure; When (2) showing, a plurality of glasswares that hold biological sample are placed on the Graphic Panel and good with the cloche cover, starting switch button then, motor is started working, and drives main shaft and Graphic Panel rotates, and is convenient to the details of observation of students biological sample; (3) shift knob is located on the Graphic Panel, thereby can close down motor as required at any time, the convenient observation.
