Description
Technical field
The utility model is related to a kind of devices for addition and subtraction teaching.
Background technology
At present, with the variation of teaching, in order to increase the reception degree of student and interest and appeal teaching, occur more
Carry out more mathematics teaching aids;But in the mathematics teaching aid of existing addition and subtraction, intelligence degree is relatively low, can not provide meter automatically
Calculate result, it is desired nonetheless to which teacher helps, and when students self study can not draw answer in time, and it is poor to learn by oneself effect.
Utility model content
The utility model provides a kind of device for addition and subtraction teaching, it is intended to for the teaching of mathematics addition and subtraction.
In order to solve the above technical problems, the utility model is achieved through the following technical solutions:
A kind of device for addition and subtraction teaching including mounting base, sliding block, U-shaped bar, processor, pressure sensor and is shown
Display screen;U-shaped bar has at least four and is set up in parallel, and the both ends of U-shaped bar are fixed in mounting base, is socketed on each U-shaped bar
Nine sliding blocks;The front side of mounting base, which is equipped with, to be located at the one-to-one display screen of U-shaped bar, each U-shaped bar below one end of front side
Pressure sensor is equipped with, each pressure sensor is electrically connected with processor, and display screen is electrically connected connection with processor and uses
The number of corresponding pressure sensor top shoe is pressed in display.
Further, the rear of each display screen is equipped with nameplate.
Further, U-shaped bar has five, and nameplate indicates successively from right to left, ten, hundred, thousand and ten thousand.
Further, the sliding block is ball or cake equipped with centre bore.
Further, mounting base is equipped with one piece of partition plate, and the both ends of every U-shaped bar are located at the both sides of partition plate respectively.
Compared with prior art the utility model has the advantages that:
In the utility model when sliding block is located at the front side of U-shaped bar, it can detect to be pressed in pressure by pressure sensor
The number of sensor top shoe simultaneously passes through corresponding display screen and is shown, can calculate automatically as a result, convenient for learning by oneself.
Description of the drawings
It, below will be to required use in embodiment in order to illustrate more clearly of the technical solution of the utility model embodiment
Attached drawing be briefly described, it should be understood that the following drawings illustrates only some embodiments of the utility model, therefore should not see

Other relevant attached drawings are obtained according to these attached drawings.
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
In the description of the utility model, unless otherwise clearly defined and limited, term " installation ", " connected ", " company
Connect ", the terms such as " fixation " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected or integral;
Can be mechanical connection or electrical connection;Can be directly connected to or be indirectly connected by intermediary, it can
To be the interaction relationship of connection inside two elements or two elements.For those of ordinary skills, may be used
To understand concrete meaning of the above-mentioned term in the utility model as the case may be.
Refering to Fig. 1, a kind of device for addition and subtraction teaching, including mounting base 1, sliding block 3, U-shaped bar 4, processor, pressure
Sensor 5 and display screen 2;U-shaped bar 4 has at least four and is set up in parallel, and the both ends of U-shaped bar 4 are fixed in mounting base 1, each U
Nine sliding blocks 3 are socketed on shape bar 4;The front side of mounting base 1 is equipped with and 4 one-to-one display screen 2 of U-shaped bar, each U-shaped bar
The 4 one end lower sections for being located at front side are equipped with pressure sensor 5, and each pressure sensor 5 is electrically connected with processor, display screen 2
Connection is electrically connected with processor and for showing the number for being pressed in 5 top shoe 3 of corresponding pressure sensor.
The rear of each display screen 2 is equipped with nameplate.
U-shaped bar 4 has five, and nameplate indicates successively from right to left, ten, hundred, thousand and ten thousand.
Sliding block 3 is ball or cake equipped with centre bore.
Mounting base 1 is equipped with one piece of partition plate 6, and the both ends of every U-shaped bar 4 are located at the both sides of partition plate 6 respectively.
Processor shows corresponding number and belongs to existing on a display screen according to the pressure change of the impression of pressure sensor
There is technology, which is not described herein again.
The operation principle of the present embodiment is:
The present embodiment has 10,010,000,000 five-digit numbers, and when carrying out plus-minus calculating, the result finally drawn can be placed on U-shaped
The front side of bar 4, the sliding block 3 of every 4 front side of U-shaped bar can be pressed in the top of pressure sensor 5, and pressure sensor passes the signal along to
Processor, processor pass the signal to display, and display shows the number for being pressed in respective sensor top shoe.
The foregoing is merely specific embodiment of the utility model, but the technical characteristics of the utility model is not limited to
This, any those skilled in the art in the field of the utility model, all cover in this practicality newly by the variation or modification made
