Description
Technical field:
The utility model relates to a kind of College Maths curves drawing plate, belongs to College Maths apparatus technical field.
Background technology:
Mathematics is a subject of the concepts such as research quantity, structure, change, space and information, belongs to the one of formal science viewed from certain angle.Be divided into higher mathematics and elementary mathematics, the also set of handlebar senior middle school complexity, algebraically, geometry are called medium mathematics.It plays irreplaceable effect in development of human history and social life, is also study and the requisite basic tool of research modern science and technology.
Mathematics stems from old Greek, and it has the meaning of study, knowledge, science.Ancient Greek scholar regards it as the starting point of philosophy, " basis of knowledge ".In addition, also have narrower and technical meaning---" Mathematics Research ".Even if in its derivation, its adjective meaning is all relevant with study, also can be used to refer to mathematics.It is at the plural form of English, and the plural form+es in French becomes, and can trace back to Latin neutral plural number (Mathematica), be translated from Greek plural number by cicero.
The knowledge of background mathematics is individual and a part indispensable in group life with using.Just considerablely in the refining of its key concept ancient mathematics text in ancient Egypt, Mesopotamia and ancient Gingko to see.From then on, its development just has progress by a small margin continuously.But algebra at that time and geometry are still in independently state for a long time.
Existing College Maths is when curve plotting, and need first to draw coordinate in board of education, then at curve plotting, its inconvenient operation, loses time.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of College Maths curves drawing plate.
A kind of College Maths curves drawing plate of the present utility model, it comprises board, hitching frame, installing frame, laser lamp, accumulator, operating switch, rack, steel band, adhesive sheet, sliding shoe, magnetic patch, the top of board is provided with hitching frame, left end and the upper end of board are all provided with installing frame, the inner homogeneous of installing frame several laser lamp is installed, accumulator, magnetic patch is installed in the inside of board, rack is arranged on the lower end of board, operating switch is arranged on the side of rack, the inside of rack is provided with steel band, the side of steel bands is bonded with adhesive sheet, sliding shoe is connected with the slide on steel band, accumulator is connected with several laser lamp by operating switch.
As preferably, described accumulator is charged lithium cells.
As preferably, the upper surface of described sliding shoe is provided with reflecting piece.
The beneficial effects of the utility model are: be convenient to fast drafting curve, easy and simple to handle, easy to use, save time, and improve work efficiency.
Accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
In figure: 1-board; 2-hitching frame; 3-installing frame; 4-laser lamp; 5-accumulator; 6-operating switch; 7-rack; 8-steel band; 9-adhesive sheet; 10-sliding shoe; 11-magnetic patch.
Embodiment:
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by the specific embodiment shown in accompanying drawing, the utility model is described.But should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
As shown in Figure 1, this embodiment is by the following technical solutions: it comprises board 1, hitching frame 2, installing frame 3, laser lamp 4, accumulator 5, operating switch 6, rack 7, steel band 8, adhesive sheet 9, sliding shoe 10, magnetic patch 11, the top of board 1 is provided with hitching frame 2, the left end of board 1 and upper end are all provided with installing frame 3, the inner homogeneous of installing frame 3 several laser lamp 4 is installed, accumulator 5, magnetic patch 11 is installed in the inside of board 1, rack 7 is arranged on the lower end of board 1, operating switch 6 is arranged on the side of rack 7, the inside of rack 7 is provided with steel band 8, the side of steel bands 8 is bonded with adhesive sheet 9, sliding shoe 10 is connected with the slide on steel band 8, accumulator 5 is connected with several laser lamp 4 by operating switch 6.
Further, described accumulator 5 is charged lithium cells.
Further, the upper surface of described sliding shoe 10 is provided with reflecting piece.
The principle of work of this embodiment is: open laser lamp 4 by operating switch 6, horizontal laser lamp can form coordinate with longitudinal laser lamp, select coordinate points, steel band 8 is inhaled on board 1 by adhesive sheet 9, when curve is restricted, slide sliding shoe 10 destination county of coordinate, is convenient to curve plotting fast, easy and simple to handle.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
