Rack for test tube is placed on lectern teacher or the hand-held rack for test tube of teacher is touring in classroom shows student, so as to allow student to fill
Divide observation experiment process and phenomenon, so as to the related chemistry knowledge that sharpens understanding.But traditional rack for test tube is only one and shelves examination
The support of pipe, when phenomenon is observed with surrounding environment poor contrast, and test tube has the interference of veiling glare behind, along with chemical anti-
The speed answered often is exceedingly fast, therefore is difficult to observe clear, and traditional rack for test tube unitary function is without secondary presentation function, demonstrating effect
Difference, it is impossible to the need for meeting teaching.
The content of the invention：
Goal of the invention of the present utility model is to overcome traditional rack for test tube observing effect in lecture experiment in the prior art
Poor deficiency, design provides a kind of new chemical experimental demonstration rack for test tube with secondary presentation function, consequently facilitating student fills
Divide and clearly observe operating process and invisible spectro reacting phenomenon.
To achieve the above object, the agent structure of the new chemical experimental demonstration rack for test tube that the utility model is related to includes square
Shape base, support body, test tube jack, background board, transparent sidekick, background card, microspur wide-angle camera, LCDs, controller,
Video recording key, play button, USB interface and control chip；Transparent support body is fixed on one end of base upper surface, is set on support body
The dorsal part for having multiple test tube jacks, support body is provided with one piece of vertical background board, and the middle and lower part of background board is provided with one upwards
The transparent sidekick of opening, is inserted with multiple background cards in slash pocket, the top of background board is provided with a microspur wide-angle camera；Base
The other end of upper surface is vertically installed with LCDs, and controller is provided with base, and control chip is provided with controller,
Four inputs and an output end are provided with control chip；Base front side be disposed with video recording key, play button and
USB interface, video recording key, play button, microspur wide-angle camera and USB interface respectively with controller in control chip four
Individual input electric signal connection, the output end of control chip is connected with LCDs electric signal；Battery is provided with base, with
Just for above-mentioned electronic component is powered；Pressing video recording key control microspur wide-angle camera carries out video acquisition, then will collection
Vision signal be input in control chip by input, video acquisition module in control chip collection video information is simultaneously deposited
Storage, presses the video information that play button will collect and is then sent in LCDs by the output end of control chip, liquid crystal
Display screen plays the video of microspur wide-angle camera collection and operating procedure, the experiment of the chemical experiment being input into by USB interface
The video and picture of phenomenon and points for attention.
The utility model compared with prior art, because this new chemical experimental demonstration rack for test tube is provided with background board, background
Card, camera and LCDs, background board, background card have the interference for blocking test tube rear veiling glare, the work(for increasing contrast
Can, consequently facilitating invisible spectro reacting phenomenon is clearly observed, and the lecture experiment can be shot with video-corder and be played to camera and display screen
Execute-in-place video or the video and picture related to the lecture experiment that prestores of broadcasting, can provide sufficient slow for student
Speed or the repeatedly chance of observation chemical experiment demonstration process and phenomenon, therefore the function with secondary presentation, so as to improve
The classroom teaching efficiency of lecture experiment.
Brief description of the drawings：
Accompanying drawing 1 is agent structure principle schematic of the present utility model.
Accompanying drawing 2 is the control principle schematic diagram of the control chip being related to of the present utility model.
Specific embodiment：
The utility model is described in further detail below by specific embodiment and with reference to accompanying drawing.
Embodiment 1：
The agent structure of the new chemical experimental demonstration rack for test tube that the present embodiment is related to includes rectangular base 1, support body 2, examination
Pipe jack 3, background board 4, transparent sidekick 5, background card 6, microspur wide-angle camera 7, LCDs 8, controller 9, video are taken the photograph
Record key 10, play button 11 and usb 12；Transparent support body 2 is fixed on one end of the upper surface of base 1, and multiple is provided with support body 2
Test tube jack 3, the dorsal part of support body 2 is provided with one piece of vertical background board 4, and the middle and lower part of background board 4 is provided with one and opens upwards
Multiple background cards 6 are inserted with the transparent sidekick 5 of mouth, slash pocket 5, the top of background board 4 is provided with a microspur wide-angle camera 7；
The other end of the upper surface of base 1 is vertically installed with LCDs 8, base 1 and is provided with controller 9, is provided with controller 9
Control chip A, is provided with four inputs A1, A2, A3, A4 and an output terminals A 5 in control chip；The front side of base 1 sets successively
