Abstract
The utility model belongs to the technical field of the teaching equipment, concretely relates to portable teaching presentation device, including strutting arrangement 2, blank 4, electronic display screen 5, its characterized in that: install strutting arrangement 2 on removing base 1, double -layered device 3 is drawn to last being provided with of strutting arrangement 2, draws double -layered device 3 to fix blank 4 on strutting arrangement 2 with electronic display screen 5 respectively, the utility model discloses a portable base has substituted the unable adjustment base of traditional show board, introduces again and draws double -layered device and the strutting arrangement through transforming, can support a blank and a electronic display screen simultaneously, having solved the removal of traditional presentation device, having turned to inflexible while, has lightened teacher's writing on the blackboard volume, has got rid of a large amount of dust that produce among the traditional teaching, has strengthened the student classroom and has understood the effect, has improved the efficiency of giving lessons.
Description
Technical field
The utility model belongs to teaching equipment technical field, is specifically related to a kind of removable teaching demonstration device.
Background technology
In the teaching practice of senior secondary course, teacher needs lead students ' reading and a large amount of outstanding model essay of explanation and really inscribe over the years usually, this not only needs very large energy, and teacher writes on blackboard limit for a long time, answer is easy to suck a large amount of dust, endanger the health of self, form occupational illness, and common Graphic Panel not only cannot show multiple true topic comparison be associated simultaneously, also cannot on-the-spot the process that it makes answer thinking be explained in detail, be unfavorable for that very much student understands digestion knowledge of awarding in court, and the writing on the blackboard that usual teacher carries out with normal blackboard, it can not move and indexing owing to can only be fixed on dais, dirigibility is poor, have impact on efficiency of giving lessons.
In sum, in prior art, there is following defect: one, blackboard is given lessons dumb, not lively, cannot promote student classroom understanding effect; Although two, demonstration blank eliminates dust harzard, write intensity still very greatly, when a large amount of true topic comparison answers, more aobvious constraint;
Utility model content
Technical problem to be solved in the utility model overcomes above-mentioned defect, provides the removable teaching demonstration device that a kind of structure is simple, easy and simple to handle.
To achieve these goals, the utility model is achieved by the following technical solutions:
A kind of removable teaching demonstration device, comprise bracing or strutting arrangement 2, blank 4, electronic display 5, it is characterized in that: movable base 1 is provided with bracing or strutting arrangement 2, bracing or strutting arrangement 2 is provided with and draws clamp device 3, draw clamp device 3 blank 4 and electronic display 5 to be fixed on bracing or strutting arrangement 2 respectively.
The described clamp device 3 that draws is 2 covers.
Described bracing or strutting arrangement 2 adopts Telescopic rod structure.
Bottom described movable base 1, universal wheel 11 is installed.
Described electronic display 5 selects capacitance touch screen.
Its beneficial effect is: the utility model adopts movable pedestal to instead of the firm banking of conventional display plate, introduce again and draw clamp device and the bracing or strutting arrangement through transformation, one piece of blank and one piece of electronic display can be supported simultaneously, solve traditional apparatus for demonstrating move, turn to inflexible while, alleviate the writing on the blackboard amount of teacher, eliminate a large amount of dust produced in conventional teaching, enhance student classroom understanding effect, improve efficiency of giving lessons.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Shown in figure: movable base 1, universal wheel 11, bracing or strutting arrangement 2, draw clamp device 3, blank 4, electronic display 5.
Embodiment
Below in conjunction with accompanying drawing 1, structure of the present utility model and beneficial effect thereof are further illustrated.
Example
A kind of removable teaching demonstration device, comprise bracing or strutting arrangement 2, blank 4, electronic display 5, it is characterized in that: movable base 1 is provided with bracing or strutting arrangement 2, bracing or strutting arrangement 2 is provided with and draws clamp device 3, draw clamp device 3 blank 4 and electronic display 5 to be fixed on bracing or strutting arrangement 2 respectively.
The described clamp device 3 that draws is 2 covers, and often cover adopts absolute construction, makes blank 4 or the electronic display 5 that can clamp different size separately, and can rotate around support bar respectively.
Described bracing or strutting arrangement 2 adopts Telescopic rod structure, can carry out suitable height adjustment according to the height at classroom landform or student seat.
Be provided with universal wheel 11 bottom described movable base 1, the universal wheel 11 installed below by movable base 1 makes this apparatus for demonstrating can move freely in classroom.
Described electronic display 5 selects capacitance touch screen, can select the capacitance touch screen of suitable size, reach effect of giving lessons preferably according to actual conditions.
Above embodiment is only the utility model a kind of embodiment wherein, and it describes comparatively concrete, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, not departing under prerequisite of the present utility model, can also make some distortion and improvement, these all belong to the protection domain of this practicality.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
