Description

Technical Field

[0001] This utility model relates to the field of blackboard drawing technology, specifically to a blackboard drawing device for English education. Background Technology

[0002] With the development of information technology, the education sector is constantly moving towards digitalization and intelligence. The market demand for intelligent teaching equipment such as interactive whiteboards is growing, prompting manufacturers to develop more advanced teaching aids. As one such tool, English education blackboard drawing devices have also gained development opportunities.

[0003] Traditional English teaching involves drawing lines on the blackboard, primarily using a ruler and chalk to manually create four lines and three grids. Teachers need to prepare 1-2 rulers of appropriate length for the blackboard and white chalk. Some may also use a set square to help establish right angles. First, on the left edge of the blackboard, use chalk to mark the height of the first line on the ruler's markings, and draw a short horizontal line along the ruler's edge on the left. Then move to the right side of the blackboard and draw a short horizontal line on the right at the same height, ensuring alignment. Hold the ruler firmly against the short horizontal lines on both sides to prevent slippage, and slowly draw the first complete horizontal line along the ruler's edge. Using the first line as a reference, estimate or use the ruler's markings to determine the spacing between lines, repeating steps 2-3 to draw the second, third, and fourth horizontal lines, ultimately forming a standardized four-line, three-grid layout.

[0004] However, with traditional methods, when drawing lines, teachers use a ruler and hold chalk to draw the lines. However, the ruler is of limited length, so it is only possible to draw horizontal and vertical lines along the edge of the blackboard. It is difficult to draw horizontal or vertical lines in the middle of the blackboard, resulting in low efficiency. Utility Model Content

[0005] To solve the above problems, this utility model provides an English education blackboard drawing device, which is achieved through the following technical solution.

[0006] An English education blackboard drawing device includes a blackboard, frames fixed to both sides of the blackboard, an extension plate fixed to the left side of one of the frames, a sliding plate fixed to the top surface of the extension plate, the sliding plate being fixed to the frame and the blackboard, a guide post fixed to the inner front side of the sliding plate, and chalk provided at the front of the blackboard. The device also includes:

[0007] A horizontal line drawing mechanism, wherein the horizontal line drawing mechanism is used for horizontal line drawing;

[0008] An adjustment mechanism is provided for adjusting the height of the drawing line and the vertical drawing line.

[0009] A fixing mechanism for fixing chalk.

[0010] As a further embodiment of this utility model, the slide plate and guide post are provided in two symmetrically distributed at the top and bottom of the blackboard.

[0011] As a further embodiment of this utility model, the transverse drawing mechanism includes a slotted plate, a connecting plate on the front side of the blackboard, a primary sliding plate fixedly connected to the top back of the connecting plate, the primary sliding plate being slidably connected to the outer wall of the guide column, a secondary sliding plate on the top of the primary sliding plate, the secondary sliding plate being fixedly connected to the connecting plate, and the secondary sliding plate being slidably connected to the outer wall of the slide rail on the top of the sliding plate. There are two primary and secondary sliding plates, which are symmetrically distributed, and a slotted plate is provided on the front side of the connecting plate.

[0012] As a further embodiment of this utility model, the card slots on the front side of the card slot plate are distributed vertically at equal intervals.

[0013] As a further embodiment of this utility model, the adjusting mechanism includes a button plate, slide rails are provided on both sides of the front part of the connecting plate, an adjusting plate is slidably connected to the inner wall of the slide rails, a partition is fixedly connected to the inner wall of the middle part of the adjusting plate, a spring is fixedly connected to the side of the partition, the button plate is fixedly connected to the side of the spring away from the partition, the button plate is slidably connected to the inner wall of the adjusting plate, the button plate is engaged with the slot plate, the spring and the button plate are symmetrically distributed on both sides of the partition, and a handle is fixedly connected to the side of the adjusting plate away from the connecting plate.

[0014] As a further embodiment of this utility model, the fixing mechanism includes a second spring, a side plate is fixedly connected to the top surface of the adjusting plate, two side plates are provided, a rotating shaft is fixedly connected to the inner side of the two side plates, a left clamping plate is rotatably connected to the front and rear parts of the outer wall of the rotating shaft, the second spring is fixedly connected to the lower left of the left clamping plate, the second spring is fixedly connected to the adjusting plate, a right clamping plate is rotatably connected to the outer wall of the middle part of the rotating shaft, a third spring is fixedly connected to the lower right of the right clamping plate, the third spring is fixedly connected to the adjusting plate, and the chalk is snapped between the left clamping plate and the right clamping plate.

[0015] The beneficial effects of this utility model are as follows:

[0034] Adjustment mechanism 3 is used to adjust the height of the drawing line and the vertical drawing line;

[0035] Fixing mechanism 4 is used to fix the chalk.

[0036] Two slide plates 14 and guide posts 15 are provided and symmetrically distributed on the top and bottom of the blackboard 11.

[0037] The fixing mechanism 4 includes a second spring 43. A side plate 41 is fixedly connected to the top surface of the adjusting plate 31. There are two side plates 41. A rotating shaft is fixedly connected to the inner side of the two side plates 41. A left clamping plate 42 is rotatably connected to the front and rear parts of the outer wall of the rotating shaft. The second spring 43 is fixedly connected to the lower left of the left clamping plate 42. The second spring 43 is fixedly connected to the adjusting plate 31.

The third spring 45 is fixedly connected to the adjusting plate 31. The chalk 16 is snapped between the left clamping plate 42 and the right clamping plate 44.

[0038] In this embodiment, as Figure 1 and Figure 4As shown, when drawing lines, press down on the left clamp 42 and the right clamp 44 simultaneously with two fingers. The left clamp 42 and the right clamp 44 rotate on the outer wall of the rotating shaft, and the second spring 43 and the third spring 45 compress downwards. Place the chalk between the left clamp 42 and the right clamp 44, release the left clamp 42 and the right clamp 44, and the second spring 43 and the third spring 45 pop up, causing the left clamp 42 and the right clamp 44 to rotate in opposite directions on the outer wall of the rotating shaft, thereby fixing the chalk and playing a fixing role. The horizontal drawing mechanism 2 is used to draw horizontal lines, and the height of the horizontal drawing is adjusted by the adjustment mechanism 3, so that vertical lines can be drawn.

[0039] Example 2

[0040] The difference from Embodiment 1 is that this embodiment discloses a transverse line drawing mechanism:

[0041] The horizontal marking mechanism 2 includes a slot plate 24. A connecting plate 21 is provided on the front side of the blackboard 11. A primary slide plate 22 is fixedly connected to the top back of the connecting plate 21. The primary slide plate 22 is slidably connected to the outer wall of the guide column 15. A secondary slide plate 23 is provided on the top of the primary slide plate 22. The secondary slide plate 23 is fixedly connected to the connecting plate 21. The secondary slide plate 23 is slidably connected to the outer wall of the slide rail provided on the top of the slide plate 14. There are two primary slide plates 22 and two secondary slide plates 23, which are symmetrically distributed. The slot plate 24 is provided on the front side of the connecting plate 21.

[0042] Preferably, the card slots on the front side of the card slot plate 24 are distributed vertically at equal intervals.

[0043] In this embodiment, as Figure 2 As shown, when drawing horizontal lines, the connecting plate 21 is manually pushed, and the secondary slide plate 23 slides on the outer wall of the slide rail at the top of the slide plate 14. At the same time, the primary slide plate 22 slides on the outer wall of the guide post 15, thereby using chalk 16 to draw horizontal lines on the surface of the blackboard 11, achieving the function of drawing horizontal lines.

[0044] Example 3

[0045] The difference between this embodiment and Embodiment 2 is that this embodiment discloses an adjustment mechanism:

[0046] The adjustment mechanism 3 includes a push plate 34. The front two sides of the connecting plate 21 are provided with slide rails. The inner wall of the slide rails is slidably connected to the adjustment plate 31. The middle inner wall of the adjustment plate 31 is fixedly connected to the partition plate 32. The side of the partition plate 32 is fixedly connected to the spring 33. The push plate 34 is fixedly connected to the side of the spring 33 away from the partition plate 32. The push plate 34 is slidably connected to the inner wall of the adjustment plate 31. The push plate 34 is engaged with the slot plate 24. The spring 33 and the push plate 34 are symmetrically distributed on both sides of the partition plate 32. The side of the adjustment plate 31 away from the connecting plate 21 is fixedly connected to the handle 35.

[0047] In this embodiment, as Figure 3As shown, when drawing vertical lines, press the two buttons 34 inward with two fingers, compressing the spring 33. This disengages the button 34 from the slot plate 24, allowing manual vertical movement and enabling the chalk 16 to draw vertical lines. To adjust the horizontal line height, press the button 34 inward with two fingers, compressing the spring 33. Once the sliding adjustment plate 31 is adjusted to the desired height, release the fingers, locking the button 34 into the slot of the slot plate 24 for adjustment.

[0048] The working principle of this utility model is as follows:

[0049] When drawing lines, press down on the left clamp 42 and right clamp 44 with two fingers simultaneously. The left clamp 42 and right clamp 44 rotate on the outer wall of the rotating shaft, and springs 2 43 and 3 45 compress downwards. Place the chalk between the left clamp 42 and right clamp 44. Release the left clamp 42 and right clamp 44, and springs 2 43 and 3 45 pop up, causing the left clamp 42 and right clamp 44 to rotate in opposite directions on the outer wall of the rotating shaft, thereby fixing the chalk. When drawing horizontal lines, manually push the connecting plate 21. The secondary slide plate 23 slides on the outer wall of the slide rail at the top of the slide plate 14, while the primary slide plate 22 slides on the outer wall of the guide post 15, thereby using the chalk 16 to draw horizontal lines on the surface of the blackboard 11. When drawing vertical lines, press the two pressing plates 34 inwards with two fingers, causing spring 1 33 to compress, thereby causing the pressing plate 34 to disengage from the slot plate 24. Manually move vertically to drive the chalk 16 to draw vertical lines. When adjusting the height of the horizontal line, press the button 34 inward with two fingers to compress the spring 33. When the sliding adjustment plate 31 is adjusted to the appropriate height, release the two fingers and lock the button 34 into the slot of the slot plate 24 to achieve the adjustment function.

[0050] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
