The present invention will be described in detail below with reference to the accompanying drawings and embodiments creates.
A kind of projection arrangement of education and instruction software easy to use, as shown in Figure 1 to Figure 3, including pedestal 1 and pedestal 1
The projecting subassembly of side setting；The projecting subassembly includes rotating on the support rod 2 and support rod 2 for be arranged in 1 side of pedestal
The projector 3 of setting；The pedestal 1 is equipped with desktop 4 and projection plate 5, and the projection plate 5 and pedestal 1 are hinged；The desktop 4
It is slidably arranged in the sliding slot 6 of pedestal, the two sides of desktop are connect by link mechanism 7 with projection plate；The link mechanism 7 includes
The second shaft 9 being arranged in the middle part of the first rotating shaft 8 and projection plate 5 of the prominent sliding slot 6 in desktop two sides, first rotating shaft 8 and second turn
It is connected between axis 9 by connecting rod 10.
The projection plate 5 is equipped with the placing modules for placing paper, which includes hinged with projection plate
Baffle 12；This projection arrangement can be placed on desk and use, and teacher plays CAI software by computer, and controls support rod
On projector computer on image be shown in making image definition by adjusting angle of the projector on support rod
On projection plate；Student can be very convenient by the image learning that shows on projection plate, and will not damage student's
Eyes；
Student can also place some blank sheet of paper on the placing modules of projection plate 5, and for recording notes, paper is placed on
Before on projection plate, baffle 12 first can be placed on placing modules along lifting, then by paper, then compress paper with baffle, this
Paper moves when sample can prevent from writing, and is more convenient student and writes；
Since image is directly projected on projection plate 5, student need not come back again and look at the blackboard, directly according on projection plate
The data logging of display, teacher can also directly operate in computer end, draw knowledge point for student, student is facilitated to remember pen
Note, can greatly speed up the speed that student records the note and absorbs knowledge；And teacher is during teaching, and it will not also be because manual
Remote controller, and thinking of giving lessons is interrupted, therefore this projection arrangement can greatly improve efficiency of giving lessons, make student's Fast Learning
Knowledge.
The desktop 6 can pull out forward, and first rotating shaft 8 is arranged at desktop rear portion；The desktop is equipped with knob 13.It throws
Shadow plate 5 can also be lifted to be used directly as display screen, is more convenient student viewing, when needing to lift projection plate, need to only use hand
Knob 13 is pulled, desktop is pulled out from pedestal, when desktop pulls out forward pedestal, first rotating shaft just will drive the shifting of connecting rod one end
Dynamic, so that connecting rod be made to lift, connecting rod just will drive projection plate and lift at this time, after projection plate lifts, only need again by adjusting projection
Angle of the instrument on support rod, so that it may which, so that image clearly is shown on inclined projection plate, such student can be at one
Comfortable angle watches projection plate, facilitates the sitting posture for adjusting student, further prevents student's hypometropia, makes student for a long time
Study is also unlikely to tired；
Meanwhile the desktop 4 of stretching can then be used to place the study articles such as books, when teacher uses projection plate display problem
When, desktop can be convenient student and be computed or looked up data, greatly increase area workable for student, and student is facilitated to write or read
It reads.
1 two sides of pedestal are equipped with the positioning component for being capable of fixing connecting rod, and positioning component includes fixture block 15, and the one of fixture block 15
End is hinged with pedestal 1, and the other end is connect by compressed spring 16 with pedestal 1.The pedestal is equipped with the appearance for accommodating fixture block
Receive slot 17, fixture block 15 is mounted in holding tank 17, the direction that fixture block 15 is pulled out with one end of compressed spring 16 towards desktop, this
Sample while connecting rod is mobile to desktop pull-out direction, will squeeze fixture block, compress compressed spring when desktop pulls out, and will
Fixture block is pushed into holding tank, and such fixture block would not stop connecting rod mobile, and connecting rod can quickly support its projection plate；
After connecting rod crosses fixture block, fixture block will pop up, fixture block under the active force that compressed spring resets out of holding tank
Connecting rod will be withstood towards one end of desktop pull-out direction, positioning action is played to connecting rod, move connecting rod can not；Pass through in this way
Connecting rod connection desktop and projection plate will also be fixed, thus make student can be used desktop or projection plate it is stable writing note
Record does not have to worry that desktop and projection plate can move in written record；
When needing to pack up desktop 4 and projection plate 5, fixture block 15 need to be only pressed into holding tank 17 with hand, fixture block will release
Then desktop 4 only need to be pushed into again sliding slot 6 by the fixation to connecting rod, desktop will be driven by link mechanism and be thrown at this time
Shadow plate is put down, and in this way by pulling desktop that can realize the control lifted or stored to projection plate, is operated very convenient.
The projector 3 can use common portable projector；The side of pedestal is arranged in projector, not only can be with
By projecting on projection plate for image clearly, and when student's written record on projection plate, projector will not be blocked,
It is shown in image on projection plate always, while projector will not interfere the normal written record of student；
The projector 3 is equipped with eye-protecting lamp 11, can provide illumination when student writes, while can also protect student
Eyes；The support rod 2 be telescopic support bar, can by adjust support rod 2 collapsing length, adjustment projector with
The distance between projection plate makes what image showed to become apparent from.It is connect by shaft with support rod in the middle part of the projector, projector
The side for lifting end towards projection plate is equipped with connecting rod 14, and the projection plate connecting rod 14 is connect with projector, connecting rod 14 and throwing
The connection type of shadow instrument and projection plate is identical as above-mentioned connecting rod；
While projection plate 5 lifts, it just will drive connecting rod 14 and lift, so that connecting rod 14 pushes projector supporting
It is rotated on bar, the angle in this way lifting projection plate is identical as rotational angle of the projector on support rod, so that on projection plate
Image can be mobile with projection plate, to make image in projection plate adjustment always on projection plate, or only occur small size
The movement of degree, subsequent need to slightly adjust projector, so that projector adjustment becomes very simple, avoid student from adjusting and lose
Accidentally, projector is damaged, the work load of teacher is also greatly reduced simultaneously, quick beginning of giving lessons can be made.
The invention replaces common display screen using projector and shows CAI software, and teacher is made to use CAI software
When giving lessons, student can directly by projection plate watch, due to projection plate compare with traditional electronic display, projection image is not
It does not only radiate, and projects the image on projection plate, eyes are entered by refraction, diffusing reflection, close to lamp, are more met
The visual custom of human eye, can effectively mitigate the asthenopia of student, visual impairment caused by fundamentally preventing because of asthenopia,
Safer eyeshield.
The invention is by setting desktop and link mechanism, so that student is by pulling desktop that can realize to projection
The control that plate is lifted or stored operates very convenient；And student can directly place paper on projection plate, for remembering
Record notes, it is not necessary to come back look at the blackboard again, directly according to the data logging shown on projection plate, teacher can also be directly in electricity
The operation of brain end draws knowledge point for student, facilitates student to record the note, can greatly speed up the speed that student records the note and absorbs knowledge
Degree.
