Description

Technical Field

[0001] This application relates to the field of mathematical teaching aids technology, and in particular to an improved writing board for mathematics teaching. Background Technology

[0002] Mathematics is the foundation of engineering, and various mathematical theories have played an important role in the development of various industries. In order to better promote the progress of mathematics, universities have established various mathematics-related disciplines. Due to the complexity of mathematics in higher education institutions, large writing boards are needed to demonstrate the calculation process of various theories. Traditional writing boards have a relatively simple structure, consisting of a large board with a writing plastic film attached to the surface, and an external frame that is fixed to the wall. Users can write directly on the surface of the writing board. This type of writing board is currently the most widely applicable, with simple structure, convenient use, and low cost.

[0003] While existing writing boards have many advantages, they still have certain limitations in practical use. Due to their large size and height, teachers may not be able to reach the top of the writing board while writing, resulting in the top part of the writing board not being fully utilized. Furthermore, the writing board is easily damaged when exposed to the elements for a long time, requiring replacement of the entire board, which reduces its lifespan and increases maintenance costs. In response, this application proposes an improved writing board for mathematics teaching, aiming to solve the problems mentioned above. Summary of the Invention

[0004] This application proposes an improved writing board for mathematics teaching, which has the advantage of height adjustment to solve the problem that the top of traditional writing boards is difficult to fully utilize.

[0005] To achieve the above objectives, this application adopts the following technical solution: an improved writing board for mathematics teaching, comprising a support chamber, a storage chamber fixedly installed at the bottom of the support chamber by welding, U-shaped grooves being formed on both sides of the inner wall of the support chamber by drilling, the U-shaped grooves being U-shaped in shape, a writing device being movably installed inside the U-shaped grooves by sliding fit, vertical grooves being formed on both sides of the inner wall of the support chamber near the middle by casting, a compaction device being movably installed inside the vertical grooves by sliding fit, a chart device being fixedly installed on the outer surface of the writing device by snap-fit, a driving device being sleeved on both sides of the inner wall of the support chamber near the bottom by shaft holes, a partition plate being fixedly installed on the back of the inner wall of the support chamber near the bottom by welding, a door being formed on the front of the storage chamber by shaft holes, and a brush strip being fixedly installed on the front of the storage chamber above the door by bolt connection.

[0006] Furthermore, the writing device includes a writing strip plate, the top and bottom of which are provided with connecting grooves by drilling. Connecting strips are fixedly installed inside the connecting grooves by snap-fit. Limiting rods are fixedly installed at both ends of the writing strip plate by welding. The writing strip plate and the connecting strips are alternately connected to form a whole. The limiting rods are slidably set inside the U-shaped grooves. The outer surface of the limiting rods cooperates with the driving device.

[0007] Furthermore, there are gaps between the writing strips, there is a color difference between the writing strips and the limiting rod, the writing strips can be divided into dark and light colors and arranged alternately according to the color depth, and the connecting strip is made of soft rubber material.

[0008] Furthermore, the compaction device includes a travel plate, with travel blocks fixedly installed at both ends of the travel plate by welding. The travel blocks are movably installed inside the vertical groove by sliding fit. A connecting plate is fixedly installed on the front of the travel plate by welding. A counterweight is fixedly installed at the bottom of the connecting plate by bolt connection. A compaction strip is fixedly installed at the bottom of the travel plate by welding. The compaction strip is in contact with one end of the integral structure formed by the writing strip and the limiting rod.

[0009] Furthermore, the drive device includes a main shaft and a roller brush. Drive gear discs are fixedly mounted on both ends of the main shaft via bolts. A drive shaft is fixedly mounted on one side of the drive gear disc via bolts. The drive shaft is movably fitted onto both sides of the inner wall of the bearing chamber through shaft holes. A drive pulley is fixedly mounted on one end of the drive shaft via bolts. A power unit is fixedly mounted on one end of the drive pulley via bolts. One end of the power unit's output shaft is connected to the drive pulley. Driven shafts are fixedly mounted on both ends of the roller brush via welding. Driven shafts are movably fitted onto both sides of the inner wall of the bearing chamber through shaft holes. A driven pulley is fixedly mounted on one end of the driven shaft via bolts. A drive belt is fitted onto the outer surface of the driven pulley, and the drive belt is simultaneously fitted onto the drive pulley.

[0010] Furthermore, there is a gap between the roller brush and the front wall of the storage compartment, through which the charting device can enter the interior of the storage compartment.

[0011] Furthermore, the chart device includes a chart board, on the back of which a locking strip is fixedly installed by welding. The locking strip is distributed in a linear array and engages with the gap between the locking strip and the writing strip. The chart is printed on the front of the chart board.

[0012] This application has the following beneficial effects.

[0013] 1. During calculations, users can ensure that the mathematical formulas they write remain aligned by observing the color changes of the writing board area, thus avoiding the problem of the formulas becoming crooked due to their length when writing horizontally. At the same time, students can also observe or record the verification steps by observing the varying shades of the writing board, thus avoiding the problem of misreading the lines due to excessively low line spacing, thereby improving the practicality of the device.

[0014] 2. When the surface of the writing strip is damaged, the user can disassemble and replace the individual writing strip, reducing the maintenance cost of the device.

[0015] 3. The writing device is compacted under the gravity of the compaction device, which avoids the writing strips being too loose and causing the user to wobble up and down during writing, thus further improving the practicality of the device.

[0016] 4. The height of the writing device can be continuously adjusted by the power unit as needed to ensure that users can easily write and record from the top, avoiding the problem that the writing board is too high and makes it difficult for users to write from the top, thus improving the ease of use of the device.

[0017] 5. The charting device is removed from the storage compartment and installed on the surface of the drive unit. The chart is then drawn directly on the charting board according to the chart, eliminating the need to draw the corresponding coordinate axes, thus improving the practicality of the device. In addition, the power unit drives the main shaft and the drive gear to rotate in opposite directions. When the writing bar rotates to the position of contact with the drive gear, the whole formed by the writing bar and the connecting strip bends, and the gap between the writing bars widens, allowing the card strip to disengage from the gap between the writing bars and fall back into the storage compartment from the gap between the inner wall of the storage compartment and the charting device, thus achieving automatic storage.

[0018] 6. During the rotation of the main shaft and drive gear disc driven by the power unit, the roller brush can be driven to rotate simultaneously. The roller brush can clean the content recorded on the surface of the writing strip, thus facilitating the next use. After resetting, the front of the writing strip faces the back of the inner wall of the carrying chamber, thus providing good protection. In addition, as the chart device detaches from the surface of the writing device and enters the storage chamber, it will simultaneously come into contact with the roller brush, reducing the falling speed of the chart device and squeezing the chart device. The surface of the brush can fully contact the front of the chart device, thereby achieving thorough cleaning of the content recorded on the surface of the chart device, further improving the automation of the device.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0034] An improved writing board for mathematics teaching, please refer to [link / reference]. Figures 1-3 The container includes a carrying chamber 1, a storage chamber 2 fixedly installed at the bottom of the carrying chamber 1 by welding, U-shaped grooves 3 are provided on both sides of the inner wall of the carrying chamber 1 by drilling, the U-shaped grooves 3 are U-shaped, and a writing device 4 is movably installed inside the U-shaped grooves 3 by sliding fit, vertical grooves 5 are provided on both sides of the inner wall of the carrying chamber 1 near the middle by casting, and a compaction device 6 is movably installed inside the vertical grooves 5 by sliding fit, a chart device 7 is fixedly installed on the outer surface of the writing device 4 by snap-fit, a drive device 8 is sleeved on both sides of the inner wall of the carrying chamber 1 near the bottom by shaft hole fit, a partition plate 9 is fixedly installed on the back of the inner wall of the carrying chamber 1 near the bottom by welding, a door 10 is provided on the front of the storage chamber 2 by shaft hole fit, and a brush strip 11 is fixedly installed on the front of the inner wall of the storage chamber 2 above the door 10 by bolt connection.

[0035] Please see Figures 3-5 The writing device 4 includes a writing strip 41. The top and bottom of the writing strip 41 are provided with connecting grooves 42 through drilling. Connecting strips 43 are fixedly installed inside the connecting grooves 42 via snap-fit. The writing strip 41 and connecting strips 43 are alternately connected to form a whole, allowing the user to disassemble and replace individual writing strips 41 if their surface is damaged. Traditional devices use an integrated writing board, requiring replacement of the entire board if damaged. The device described in this application avoids this limitation, reducing maintenance costs. Limiting rods 44 are fixedly installed at both ends of the writing strip 41 by welding. The writing strip 41 and connecting strips 43 are alternately connected to form a whole. The limiting rods 44 are slidably fitted inside the U-shaped groove 3, and their outer surface engages with the driving device 8.

[0036] Please see Figures 1-3There are gaps between the writing strips 41, and there is a color difference between the writing strips 41 and the limiting rod 44. The writing strips 41 can be divided into dark and light colors and arranged alternately according to the color depth. During the calculation process, the user can ensure that the mathematical formulas recorded are aligned according to the color change of the writing area, avoiding the problem of skewing due to the length of the formula during horizontal writing. At the same time, students can also observe or record the calculation steps according to the color change of the writing strip, avoiding the problem of misreading the formula due to the low line spacing on the writing strip, thus improving the practicality of the device. The connecting strip 43 is made of soft rubber material.

[0037] Please see Figures 3-4 and Figures 6-8 The compaction device 6 includes a travel plate 61. Travel blocks 62 are fixedly installed at both ends of the travel plate 61 by welding. The travel blocks 62 are movably installed inside the vertical groove 5 by sliding fit. A connecting plate 63 is fixedly installed on the front of the travel plate 61 by welding. A counterweight block 64 is fixedly installed at the bottom of the connecting plate 63 by bolt connection. A compaction strip 65 is fixedly installed at the bottom of the travel plate 61 by welding. The compaction strip 65 is in contact with one end of the whole formed by the writing strip 41 and the limiting rod 44. The weight of the entire compaction device 6 will act on the top of the writing device 4 and compact the writing device 4, which is located in front of the bearing chamber 1, under the gravity of the compaction device 6. This prevents the writing strip 41 from being too loose, which would cause the user to wobble up and down during writing, and further improves the practicality of the device.

[0038] Please see Figure 3 and Figure 9The drive unit 8 includes a main shaft 81 and a roller brush 82. Drive gear discs 83 are bolted to both ends of the main shaft 81. A drive shaft 84 is bolted to one side of the drive gear disc 83. The drive shaft 84 is movably fitted into both sides of the inner wall of the bearing chamber 1 via shaft holes. A drive pulley 85 is bolted to one end of the drive shaft 84. A power unit 86 is bolted to one end of the drive pulley 85. One end of the output shaft of the power unit 86 is connected to the drive pulley 85. Driven shafts 87 are welded to both ends of the roller brush 82. The driven shafts 87 are movably fitted into both sides of the inner wall of the bearing chamber 1 via shaft holes. One end of the 7 is fixedly installed with a driven pulley 88 by bolts. A transmission belt 89 is sleeved on the outer surface of the driven pulley 88. The transmission belt 89 is also sleeved with the driving pulley 85. The main shaft 81 and the drive gear plate 83 are driven to rotate together by the power machine 86. The height of the front side of the writing device 4 can be adjusted. The user can start writing from the top of the front of the writing device 4 and continuously adjust the height of the writing device 4 by the power machine 86 as needed to ensure that the user can easily write from the top. This avoids the problem that the writing board is too high and the user has difficulty writing from the top of the writing board, thus improving the ease of use of the device.

[0039] Please see Figures 3-5 and Figure 9 There is a gap between the roller brush 82 and the inner wall of the storage compartment 2, allowing the chart device 7 to enter the storage compartment 2. A transmission belt 89 is fitted onto the outer surface of the driven pulley 88, and the transmission belt 89 is also fitted onto the driving pulley 85. This allows the roller brush 82 to rotate simultaneously while the power unit 86 drives the main shaft 81 and the drive gear 83. During the resetting process of the writing device 4, the roller brush 82 can clean the content recorded on the surface of the writing strip 41, making it convenient for the next use. At the same time, the front of the reset writing strip 41 faces... The back of the inner wall of the bearing chamber 1 provides excellent protection, preventing damage to the surface of the writing strip 41 during non-use periods and improving the stability of the device. In addition, as the chart device 7 detaches from the surface of the writing device 4 and enters the storage chamber 2, it simultaneously comes into contact with the roller brush 82, thereby reducing the falling speed of the chart device 7 and squeezing the chart device 7. This allows the surface of the brush strip 11 to fully contact the front of the chart device 7, thus achieving thorough cleaning of the content recorded on the surface of the chart device 7 and further improving the automation of the device.

[0040] Please see Figures 3-5 and Figures 9-11The chart device 7 includes a chart plate 71. A retaining strip 72 is welded to the back of the chart plate 71. The retaining strips 72 are arranged in a linear array and engage with the gaps between them and the writing strips 41. Charts are printed on the front of the chart plate 71. There are gaps between the writing strips 41, and the retaining strips 72 engage with the gaps between them. When a user needs to use a combination of text and graphics for teaching, they can directly remove the chart device 7 from the storage compartment 2, install it on the surface of the drive device 8, and draw directly on the surface of the chart plate 71 according to the charts, without needing to... The need to draw corresponding coordinate axes improves the practicality of the device. In addition, when the device is finished, the power unit 86 drives the main shaft 81 and the drive gear 83 to rotate in opposite directions, thereby driving the writing device 4 to reset. When the writing strip 41 rotates to the position of contact with the drive gear 83, the whole formed by the writing strip 41 and the connecting strip 43 is bent, and the gap between the writing strips 41 becomes larger, so that the card strip 72 can disengage from the gap between the writing strips 41 and fall back into the interior of the storage compartment 2 through the gap between the inner wall of the storage compartment 2 and the chart device 7, realizing automatic storage and providing automation of the device.

[0041] The method of using this invention is as follows:

[0042] During use, users can ensure that the mathematical formulas written on the writing board remain aligned by observing the color changes of the writing board area during calculations. Students can also observe or record verification steps based on the varying shades of the writing board. If the surface of a writing strip 41 is damaged, the user can disassemble and replace that individual writing strip 41. The overall weight of the compaction device 6 acts on the top of the writing device 4, compacting the writing device 4 located in front of the bearing chamber 1 under the gravity of the compaction device 6. The power unit 86 drives the main shaft 81 and the drive gear 83 to rotate together, allowing adjustment of the front of the writing device 4. The height of the writing device 4 allows the user to start writing from the top of the front side and continuously adjust the height of the writing device 4 as needed via the power mechanism 86, ensuring that the user can easily write and record from the top. There are gaps between the writing strips 41, and the locking strip 72 engages with the gap between the writing strips 41. The front of the chart board 71 is printed with charts. When the user needs to use a combination of text and graphics for teaching, they can directly take out the chart device 7 from the inside of the storage compartment 2, install it on the surface of the drive device 8, and draw directly on the surface of the chart board 71 according to the chart, without having to draw the corresponding coordinate axes. When the device is finished using, the power unit 86 drives the main shaft 81 and the drive gear 83 to rotate in opposite directions, thereby resetting the writing device 4. When the writing strip 41 rotates to the position of contact with the drive gear 83, the whole formed by the writing strip 41 and the connecting strip 43 is bent, and the gap between the writing strips 41 becomes larger, allowing the retaining strip 72 to disengage from the gap between the writing strips 41 and fall back into the storage compartment 2 through the gap between the inner wall of the storage compartment 2 and the chart device 7. During the process of the power unit 86 driving the main shaft 81 and the drive gear 83 to rotate, the roller brush 82 can be driven to rotate simultaneously, making... During the resetting process of the writing device 4, the roller brush 82 can clean the content recorded on the surface of the writing strip 41, thus facilitating the next use. At the same time, the front of the reset writing strip 41 faces the back of the inner wall of the carrying chamber 1, thus providing good protection. As the chart device 7 detaches from the surface of the writing device 4 and enters the storage chamber 2, it will simultaneously come into contact with the roller brush 82, thereby reducing the falling speed of the chart device 7 and squeezing the chart device 7, so that the surface of the brush strip 11 can fully contact the front of the chart device 7, thereby achieving thorough cleaning of the content recorded on the surface of the chart device 7.
