Abstract
The utility model relates to a teaching instrument, in particular to a chemical experiment video demonstration device, which comprises a test box. A reaction container installation position and a camera device are arranged in the test box, wherein the camera device faces towards the reaction container installation position. The chemical experiment video demonstration device additionally comprises a display device. The video output end of the camera device is electrically connected with the video input end of the display device. The reaction container installation position comprises installation holes which are arranged on the upper surface of the test box and installation brackets which are arranged in the test box. By using the chemical experiment video demonstration device, videos of a chemical experiment can be acquired and be displayed on the display device with a large screen, all students can see the experiment clearly, the times of repeating the experiment by a teacher can be reduced, the time, the effort and chemical reagent can be saved and the teaching quality can be improved.
Description
Technical field
The utility model relates to a kind of instruments used for education, is specifically related to a kind of chemical experiment video display device.
Background technology
In middle school chemistry education; the teacher for the student demonstrate chemical experiment be the teaching in important step; but since middle school chemical experiment usually with test tube, beaker as reaction vessel; and some chemical experiment phenomenons are trickleer; every must student far away being difficult to see clearly, therefore, in existing teaching; the teacher can repeat to do experiment usually in face of many group students in batches, loses time and the labour.
The utility model content
In view of this, in order to address the above problem, the utility model provides a kind of chemical experiment video display device, can gather the video of chemical experiment and plays on the display device of giant-screen.
The purpose of this utility model is achieved in that chemical experiment video display device, comprises chamber, is provided with the reaction vessel installation position in the described chamber, also is provided with camera head, described camera head orientating reaction container installation position.
Further, also comprise display device, the video output terminals of described camera head is electrically connected with the video inputs of display device.
Further, described reaction vessel installation position comprises the mounting hole that is arranged at the chamber upper surface and is arranged at installation bracket in the chamber.
Further, described mounting hole comprises the test tube mounting hole that at least one size and test tube adapt, and at least one big or small beaker mounting hole that adapts with beaker, described installation bracket comprises test tube carriage and beaker carriage, the test tube carriage is provided with the test tube spacing hole, and the beaker carriage is provided with the beaker spacing hole.
Further, described test tube carriage and beaker carriage are arranged in the chamber by arrangement for adjusting height.
The beneficial effects of the utility model are: chemical experiment video display device of the present utility model, can gather the video of chemical experiment and on the display device of giant-screen, play, make all students all see experimental phenomena clearly, the teacher also can reduce the number of times of repeated experiments, save time, labour and chemical reagent, improve the quality of teaching simultaneously.
Description of drawings
In order to make the purpose of this utility model, technical scheme and advantage clearer, the utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 shows the structural representation of chemical experiment video display device.
Embodiment
Referring to Fig. 1, chemical experiment video display device, comprise chamber 1, be provided with the reaction vessel installation position in the described chamber 1, also be provided with camera head 2, described camera head 2 orientating reaction container installation positions, the video output terminals of described camera head 1 is electrically connected with the video inputs of display device 3.In the present embodiment, the reaction vessel installation position comprises the test tube mounting hole 4 that 3 sizes being arranged at the chamber upper surface and test tube adapt, the beaker mounting hole 5 that size and beaker adapt, be respectively arranged with test tube carriage 6 and beaker carriage 7 in the chamber below test tube mounting hole 4 and beaker mounting hole 5, described test tube carriage 6 is provided with test tube spacing hole 8, described beaker carriage 7 is provided with beaker spacing hole 9, described test tube carriage 6 and beaker carriage 7 can be fixedly set in the madial wall of chamber 1, also can be arranged in the chamber 1 by the arrangement for adjusting height (not shown), so that the height according to test tube and beaker is regulated, make the key reaction zone over against camera head, obtain better demonstration video.Described arrangement for adjusting height can be adjustable for height base, it also can be the slide rail that can slide up and down that is arranged at chamber 1 madial wall, one end of described test tube carriage 6 and beaker carriage 7 slidably is connected with described slide rail, can also be that the different a plurality of slots of height and position are set on chamber 1 madial wall, can insert corresponding slot internal fixation with an end of test tube carriage 6 and beaker carriage 7 as required.
The above is only for the utility model that preferably is not limited to of the present utility model, and obviously, those skilled in the art can carry out various changes and modification and not break away from spirit and scope of the present utility model the utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
