Description

Technical Field

[0001] The invention relates to the technical field of economic management teaching, and in particular to a recording data display device used for economic management teaching. Background Art

[0002] The economic management data display device is a device for displaying economic management data, which is usually used to display the data in a linear form on the screen so that users can easily view and understand the data. The Chinese invention patent with the publication number CN112466192B discloses an economic data curve change display device, which drives the gas to move in the limit cavity through the pressure difference formed between the limit cavity and the air bag, so that the points of the relevant curves of economic data in economics can be clearly represented, so that the changes of the economic curves in economics can be vividly displayed; the Chinese invention patent with the publication number CN118522210A discloses a data linear display device for economic management teaching, according to the data table to be displayed, the numerical plate is moved upward, and when the top edge of the numerical plate is flush with the scale line corresponding to the data, the numerical plate is fixed, and when other data on the statistical table need to be displayed, the above steps are repeated to move the numerical plate corresponding to the data to the height of the corresponding data scale plate. At this time, the numerical plate is a bar chart, so that the device can quickly draw a bar chart with simple operation, thereby saving time and improving teaching efficiency.

[0003] In the related art, in order to change the traditional dust problem of drawing economic curves directly on the blackboard with chalk, most of the existing data display devices use a structure to display data on a transparent display board. However, although this method has the function of data display, it lacks the function of data recording. In the process of display, its display structure is easy to interfere with students' concentration and affect their teaching quality. In addition, the display structure cannot be displayed separately when performing column statistics and linear statistics on data, so that overlapping data statistical graphs are difficult to distinguish and observe, which reduces the data display effect.

[0043] The recording assembly 4 includes a plurality of operating rods 41 slidably connected to the inside of the drawing tank 2, the outer surfaces of the plurality of operating rods 41 are provided with columnar recording members 45, and a linear recording member 46 is provided between one ends of the plurality of operating rods 41, and the inside of the drawing tank 2 is provided with a plurality of pigment tanks 44;

[0044] By manually extending and retracting a plurality of operating rods 41, not only can a columnar statistical graph be drawn on the drawing surface of the transparent display board 3 through a plurality of columnar recording members 45, but the linear recording members 46 can also be simultaneously unfolded. By the unfolded linear recording members 46 contacting the drawing surface of the transparent display board 3, a linear statistical graph can be formed, and classified display is performed through the transparent display board 3, which has the functions of data display and data recording, and solves the problem that the data display device in the prior art usually adopts a structural display method. Although it has a data display function, its display structure is easy to interfere with the students' concentration during the display process, affecting its teaching quality.

[0045] Refer to the attached Figure 5 The cylindrical recording member 45 includes a sleeve frame 451 fixed to the outer surface of the operating rod 41, and a liquid absorbing cotton block 452 is fixedly connected to the interior of the sleeve frame 451, and the bottom of the liquid absorbing cotton block 452 extends into one of the pigment grooves 44;

[0046] The front and rear movement of the operating rod 41 can drive the sleeve frame 451 to move forward and backward, and then drive the absorbent cotton block 452 to move forward and backward, and then the absorbent cotton block 452 can be used to perform columnar painting on the depiction surface of the transparent display board 3;

[0047] The bottom of the absorbent cotton block 452 extends into one of the pigment grooves 44 , so that the absorbent cotton block 452 can absorb the liquid pigment inside the pigment groove 44 , so as to provide pigment for the painting of the absorbent cotton block 452 .

[0048] Refer to the attached Figure 5 The linear recording member 46 includes a sleeve 461 fixed to one end of a plurality of operating rods 41, and a plurality of liquid-absorbing cotton rods 462 are fixedly connected inside the plurality of sleeves 461, and the bottom ends of the plurality of liquid-absorbing cotton rods 462 extend to the corresponding pigment grooves 44 below, and an elastic rope 463 is fixedly connected between the top ends of the plurality of liquid-absorbing cotton rods 462, and the elastic rope 463 is made of elastic fabric with liquid-absorbing function.

With the driving of the plurality of operating rods 41, the absorbent cotton block 452 can draw a column on the drawing surface of the transparent display board 3 to form a columnar statistical graph.

[0053] After the columnar statistical drawing is completed, the drawing surface of the transparent display board 3 moves downward, and the plurality of absorbent cotton rods 462 and the interconnected elastic ropes 463 in the linear recording member 46 can contact the drawing surface of the transparent display board 3 to form a linear statistical graph.
