Description

Technical Field

[0001] This invention belongs to the field of mathematics teaching technology, specifically relating to a device for explaining bar graphs in mathematics. Background Technology

[0002] In teaching mathematics, it is often necessary to explain bar graphs. A bar graph is a statistical chart that uses long bars to represent data. The length of each bar represents the numerical value of the corresponding data, and the width of the bars is usually the same.

[0003] Chinese patent CN218729515U discloses a bar graph explanation device for elementary school mathematics, comprising: a standing plate with multiple guide grooves on its outer surface; multiple lifting components, each including a slider and a lead screw, the slider being disposed within a corresponding guide groove and slidably connected to the inner wall of the guide groove, the lead screw passing longitudinally through the slider and rotatably connected at both ends to the inner wall of the guide groove, the lead screw being threadedly connected to the slider; and multiple winding components, each corresponding to one of the lifting components, each winding component including a rotating shaft, a rolled cloth, and a torsion spring, both ends of the rotating shaft being rotatably connected to the inner wall of the guide groove, the first end of the rolled cloth being wound around the rotating shaft and fixedly connected to the rotating shaft, the second end of the rolled cloth being fixedly connected to the corresponding slider, and the torsion spring being sleeved on the rotating shaft, the torsion spring causing the second end of the rolled cloth to tend to approach the rotating shaft.

[0004] The bar chart explanation device in the aforementioned comparative patent can be quickly adjusted according to the teacher's needs, reducing the teacher's workload and improving teaching efficiency. However, it cannot perform multiple splicing operations between bar charts, making it unsuitable for different types of bar charts. Furthermore, it is not easy to clean chalk dust from the chart, causing chalk dust to adhere to the chart and affecting the viewing experience during statistical teaching. Summary of the Invention

[0005] The purpose of this invention is to provide a bar graph explanation device for mathematics, so as to solve the problems mentioned in the background art.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1:

[0032] Please see Figures 1-5 As shown, a bar graph explanation device for mathematics includes:

[0033] Plate 1;

[0034] Strip plate mechanism 2, which is disposed on the outside of plate body 1;

[0035] The cleaning mechanism 3 is installed on the outside of the strip plate mechanism 2;

[0036] The winding mechanism 4 is located inside the strip plate mechanism 2;

[0037] Cleaning mechanism 5 is installed on the outer wall of strip plate mechanism 2.

[0038] The strip plate mechanism 2 includes a display plate 201, a first slide groove 202, a sliding block 203, and a display belt 204. The display plate 201 is disposed on the outside of the plate body 1. The first slide groove 202 is provided on the inner side wall of the display plate 201. The sliding block 203 is inserted into the inside of the first slide groove 202. The bottom end of the sliding block 203 is connected to the display belt 204. The second slide groove 205 is provided on the outer side wall of the display plate 201. An adsorption plate 206 is fixedly connected to the outside of one side of the display plate 201. The sliding block 203 is slidably connected to the outside of the first slide groove 202. The display belt 204 is wound up outside the winding mechanism 4. The adsorption plate 206 is fixedly connected to the outside of one side of the display plate 201. A rectangular insert is fixedly connected to the outside of one side of the display plate 201. The outer surface of the display belt 204 is a rough elastic cloth.

[0039] Specifically, by inserting the rectangular blocks on the display panel 201 into the second slide groove 205, multiple display panels 201 can be spliced ​​together, making them suitable for different bar charts. When the sliding block 203 slides and stretches inside the first slide groove 202, the display strip 204 can be easily unfolded, allowing for a more intuitive representation of the chart and the writing and marking on the display strip 204.

[0040] As can be seen from the above, when splicing between display panels 201, the second slide 205 enables splicing between multiple display panels 201, making it suitable for displaying various bar charts. The sliding block 203 is inserted inside the first slide 202, which facilitates the sliding and stretching of the display belt 204, making it easy to adjust the height of the sliding block 203 on the display panel 201, thus facilitating the display of bar chart data.

[0041] refer to Figure 2 and Figure 5 As shown, the cleaning mechanism 3 includes a cleaning head 301, a first penetration hole 302, and a collection cylinder 303. The cleaning head 301 is disposed outside the strip plate mechanism 2. Multiple first penetration holes 302 are opened on the outer surface of the cleaning head 301. The collection cylinder 303 is inserted inside the cleaning head 301. Multiple second penetration holes 304 are opened on the outer surface of the collection cylinder 303. The second penetration holes 304 are evenly opened on the outer surface of the collection cylinder 303. The outer surface of the cleaning head 301 is made of a rough-structured rubber material. The collection cylinder 303 is rotatably connected to the inner side wall of the display panel 201.

[0042] Specifically, by cleaning the surface of the display belt 204 with the cleaning head 301, the chalk dust on the outside of the display belt 204 can be cleaned. The cleaned chalk dust falls into the inside of the collection cylinder 303 through the first penetration hole 302 for collection.

[0043] Example 2:

[0044] refer to Figures 1-5 As shown, the winding mechanism 4 includes a rotating base 401, a rotating rod 402, and a torsion spring 403. The rotating base 401 is fixedly connected to the inner wall of the display panel 201. A torsion spring 403 is fixedly connected to the outside of one side of the rotating base 401. The rotating rod 402 is inserted inside the rotating base 401. A sleeve 404 is fixedly connected to the outside of one side of the rotating rod 402. A display belt 204 is sleeved on the outside of the sleeve 404. The rotating rod 402 is rotatably connected inside the rotating base 401. The torsion spring 403... One side is fixedly connected to the outside of the sleeve 404. The sleeve 404 is elastically telescopically connected to the torsion spring 403. The cleaning mechanism 5 includes a water storage tank 501, a rotating shaft 502 and a wetting wheel 503. The water storage tank 501 is fixedly connected to the inner side wall of the display panel 201. The rotating shaft 502 is installed at the bottom of the water storage tank 501. The wetting wheel 503 is rotatably connected inside the rotating shaft 502. The wetting wheel 503 abuts against the outside of the cleaning head 301. A water outlet groove is opened at the lower end of the water storage tank 501.

[0045] Specifically, the water outlet at the bottom of the water storage tank 501 can continuously drip water onto the wetting wheel 503, thereby wetting the cleaning head 301 and improving the efficiency of cleaning chalk dust on the surface of the display belt 204. Furthermore, the elastic contraction between the sleeve 404 and the torsion spring 403 allows the display belt 204 to be easily wound up and unwound outside the sleeve 404.

[0046] As can be seen from the above, when the sliding block 203 is pulled down and retracted, the cleaning head 301 abuts against the surface of the display belt 204 to clean the chalk dust on the surface of the display belt 204. The cleaned dust is collected and processed inside the collection cylinder 303 through the penetration of the first penetration hole 302 and the second penetration hole 304. At this time, the outside of the cleaning head 301 abuts against the surface of the wetting wheel 503, which can wet the surface of the cleaning head 301, thus facilitating the cleaning head 301 to wet and clean the display belt 204 when cleaning it.
