Description
Technical field
A kind of multimedia teaching facility is the utility model is related to, is a kind of religion being applied in teaching in more detail
The dais of room teaching.
Background technology
In present school instruction, multi-media classroom turns into essential educational aid, and multi-media classroom is by more matchmakers
The various moderns such as body computer, liquid crystal projector, digital video frequency display table, central control system, projection screen, stereo set are taught
Learn equipment composition.
But for the multi-media classroom that so many equipment is formed, will necessarily cost it is very high, therefore general condition
School is only equipped with several multi-media classrooms with whole auxiliary facilities, it is desirable to realizes entirely multi-media classroom for current
Fund of teaching for or it is difficult.
In order to save cost, existing school also uses projecting apparatus being placed directly on a desk and attended class for student.But
That the camera lens of projecting apparatus highly adjusts and but annoyings teacher's teaching because want regulation to proper angle and will projection it is upright also
Be it is highly difficult, it is just no longer handy using the angle demodulator of existing discrete spacing here.
And in view of the weight of student's schoolwork burden now, correspondingly the daily hours of instruction of teacher will be very long, therefore is awarding
Feel exhausted during class, will alleviate much if can lean against and be taught on backed chair；But of the prior art say
Platform is all rectangle desktop, if leaning against both hands on chair back can't reach the notebook computer placed on the desktop at dais.
In summary, inventor combines experience for many years, invented it is a can solve the problem that it is above-mentioned it is of all the problems can be real
The now dais of simple multimedia teaching.
The content of the invention
If reach notebook computer and throwing on dais to overcome class-teaching of teacher in the prior art to lean against the chair back
The inconvenient technological deficiency of shadow instrument angular adjustment, the utility model provide a kind of Multi-media teaching platform, the multimedia teaching
Dais can lean against on the chair back and teach during teachers ' teaching, and the angle of projecting apparatus is easy to adjust.
To achieve these goals, the present invention provides following technical scheme：
A kind of Multi-media teaching platform, including table leg and desktop, two phases are provided with the downside in the middle part of the desktop
Mutually parallel guide rail, the length direction of the guide rail is vertical with the long side of the desktop and the guide rail extends beyond the desktop
Long side；The slideway slided for pulley is offered in the middle part of the guide rail, and the slideway extends to the length of the desktop
The circular duct being connected with the slideway is converted to after at side；Also include pull plate, the width of the pull plate is less than two
The distance between guide rail, and pulley is provided with two sides of the length direction of the pull plate, the pulley is symmetrically set
Put on two sides of the length direction of the pull plate, and the pulley is slidably arranged in adjacent slideway
It is interior；The external diameter of the pulley is more than the diameter in the circular duct；The pull plate can be by the pulley in the circular port
Rotated in road and reverse flip on the desktop；Circular hole is offered in the middle part of the desktop, cylinder, institute are provided with circular hole
The circular hole can be passed by stating the external part of cylinder；The pull plate can reverse flip to stretching by the cylinder above the desktop
Go out end support.
Above-described Multi-media teaching platform, in the application teacher can lean against on the chair back and pull out pull plate, pay attention to
It not move circular duct opening position to, then notebook computer is placed on pull plate, it is possible to extend the supporting surface of desktop
Product, realizes the purpose against teaching on the chair back.Of course, need to use projecting apparatus broadcasting teaching unreal for classmates in teacher
When lamp piece or film, it is only necessary to the pulley set on pull plate is pulled out in circular duct, using circular duct as rotary shaft,
Pull plate described in can reverse flip, after pull plate upset, supported by the external part of cylinder, adjust the folder of pull plate and desktop
Angle only needs to adjust the extension elongation of cylinder.
In order to pull plate pull out desktop long side after it is more stable in the height direction, avoid the occurrence of pull plate pull out after take out
Arm-tie influences the placement security of notebook computer for inclined plane, and the technical scheme that can be used is, the pull plate it is upper
Elastic cushion block is provided with surface, the elastic cushion block is located at the inboard edge placement of the pull plate upper surface.
Further improved technical scheme also includes, and the quantity of the elastic cushion block is at least three, multiple elasticity
Line between cushion block is broken line.
In order to realize that the protrusion height of cylinder can be adjusted precisely (using the air inlet of small tolerance input cylinder to gas
Micro rise of the external part of cylinder is realized), the technical scheme that can be selected, which is that the air inlet of the cylinder is connected by tracheae, inflates
Capsule, the afterbody of the aerated capsule is provided with afterbody check valve.
The air intake structure of above-described cylinder is identical with sphygmomanometer air intake structure.
Further improved technical scheme also includes, and pressure release is additionally provided with the tracheae being connected with the air inlet of the cylinder
Valve.
Because in classroom teaching, teacher is generally to stand in demonstration courseware, because it is more vivid so to teach.
But if teacher teaches on one's feet, just occur that the notebook computer put on dais is less than the position that teacher's arm naturally droops
Height is put, is not easy to Operational Note this computer, is for this technical scheme that can be selected, it is vertical by least three on the desktop
Post supports a small table surface that can place notebook computer.
The size of small table surface is more than the size of notebook computer.
Further improved technical scheme includes, and all columns are Collapsible structures.
Further improved technical scheme includes, and the telescopic altitude range of column is 0~30cm.
In order to cause the external part of pull plate and cylinder to be combined together well, the technical scheme that can select
It is that the external part of the cylinder is provided with magnet, the external part relevant position on the pull plate with the cylinder is provided with iron
Block.
In order that projecting apparatus can be securely placed on pull plate and be not easy slide and notebook computer be not easy to slide
Dynamic, the technical scheme that can be used is that the front and back of the pull plate is provided with anti-slip veins.
The utility model have the advantage that including：
Pull plate can be pulled open when class-teaching of teacher has tired out to be placed on notebook computer above, and is leaned against on the chair back
Work；When needing presentation slides or film, notebook computer can be placed on above, led to by overturning pull plate
The angle of the height regulation projecting apparatus of toning displacements of cylinders external part, can be achieved fine setting, is easy to regulation to arrive correct position；It is unreal when demonstrating
During lamp piece, notebook computer can also be placed on small table surface, be easy to teacher to operate notebook computer, avoid and bend over to grasp
That makees is tired out.
