Abstract
The utility model discloses a formula projecting apparatus in mathematical education, it contains projecting apparatus body (1), and connecting plate (2) are outwards extended to the one end of this projecting apparatus body (1) bottom, the other end of connecting plate (2) upwards extends mounting panel (3) perpendicularly, and the last top surface of this mounting panel (3) flushes with the last top surface of projecting apparatus body (1), mounting panel (3) on install and go up projection hole (4) corresponding amplifier (5) with projecting apparatus body (1), projecting apparatus body (1) on be provided with the laminating the gliding position sleeve of its lateral surface (6). The utility model discloses simple structure, convenient to use, during the use, with mounting panel and position sleeve lock good, insert the constant head tank with the mathematical formula film from the slot in, through the projection hole can with the mathematical formula projection on the mathematical formula film to the projection curtain, and owing to be provided with the amplifier on the mounting panel, therefore can enlarge the mathematical formula that the projection was come out, more clear.
Description
Technical field
This utility model relates to tutor auxiliary platform apparatus field, the formula projection being specifically related in a kind of mathematical education
Instrument.
Background technology
The study of mathematical formulae plays very important effect in daily teaching process, and student is learnt well number
Play conclusive effect, and existing mathematical formulae especially higher mathematics formula is the most more complicated, always
Teacher usually there will be mistake during writing on the blackboard, and most teacher is typically all and first finishes writing inspection with small blackboard
Good, then it is suspended on big blackboard for Students ' Learning, occurs during writing on the blackboard although this method can reduce
The probability of mistake, but very inconvenient, it is impossible to repeatedly use, and can not meet existing
The teaching of generationization.
Utility model content
This utility model purpose is to provide the formula projector in a kind of mathematical education, and it can efficiently solve the back of the body
Problem in the presence of scape technology.
In order to solve the problem in the presence of background technology, it comprises projector main body 1, this projector main body 1
One end of bottom extends outward connecting plate 2, and the other end of described connecting plate 2 upwards vertically extends installing plate
3, the upper end face of this installing plate 3 flushes with the upper end face of projector main body 1, and described installing plate 3 is installed
There is the amplifier 5 corresponding with projection hole 4 on projector main body 1, described projector main body 1 is provided with
Fit its lateral surface slide positioning sleeve 6, the bottom of described projection hole 4 is provided with location-plate 7, this location-plate
Offer on 7 be available for mathematical formulae film gap insert locating slot 8, the upper end face of described positioning sleeve 6 to
Inside offer slot 9, after positioning sleeve 6 and installing plate 3 fasten completely, described slot 9 and locating slot 8
Corresponding.
Owing to have employed above technical scheme, this utility model has the advantages that simple in construction, makes
With convenient, during use, installing plate and positioning sleeve being fastened, it is fixed to be inserted into from slot by mathematical formulae film
In the groove of position, the mathematical formulae on mathematical formulae film can be projected on projection screen by projection hole, and by
Amplifier it is provided with, therefore, it is possible to be amplified by the mathematical formulae projected, more clearly on installing plate
Clear, it is simple to the student sat in the back row can be clearly visible that, and mathematical formulae film can be used for multiple times, energy
Enough teaching meeting modernization.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model, below in conjunction with accompanying drawing, embodiment is briefly described.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be readily apparent from effect
Understand, below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment
Scheme is clearly and completely described.
Referring to Fig. 1, this detailed description of the invention is to be achieved by the following technical solutions, and it comprises projector originally
Body 1, the one end bottom this projector main body 1 extends outward connecting plate 2, the other end of described connecting plate 2
Upwards vertically extending installing plate 3, the upper end face of this installing plate 3 flushes with the upper end face of projector main body 1,
The amplifier 5 corresponding with projection hole 4 on projector main body 1 is installed on described installing plate 3, described
Being provided with the positioning sleeve 6 that its lateral surface of fitting slides on projector main body 1, the bottom of described projection hole 4 is arranged
There is location-plate 7, this location-plate 7 offers and is available for the locating slot 8 that mathematical formulae film gap inserts, described
The upper end face of positioning sleeve 6 inwardly offer slot 9, after positioning sleeve 6 and installing plate 3 fasten completely, institute
The slot 9 stated is corresponding with locating slot 8.
Owing to have employed above technical scheme, this detailed description of the invention has the advantages that simple in construction,
Easy to use, during use, installing plate and positioning sleeve are fastened, mathematical formulae film is inserted into from slot
In locating slot, the mathematical formulae on mathematical formulae film can be projected on projection screen by projection hole, and
Owing to being provided with amplifier on installing plate, therefore, it is possible to the mathematical formulae projected is amplified, more
Clearly, it is simple to the student sat in the back row can be clearly visible that, and mathematical formulae film can be used for multiple times,
Disclosure satisfy that the teaching of modernization.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, rather than right
It limits；Although this utility model being described in detail with reference to previous embodiment, this area common
It will be appreciated by the skilled person that the technical scheme described in foregoing embodiments still can be modified by it,
Or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make corresponding skill
The essence of art scheme departs from the spirit and scope of this utility model each embodiment technical scheme.
