Description

Technical Field

[0001] The utility model relates to the technical field of teaching tools, in particular to an English teaching board. Background Art

[0002] A teaching board is a device used for writing and demonstration in the education industry. Usually, a teaching board is placed in a classroom or conference room, and content is written with chalk or water-based pen to serve the purpose of explanation and demonstration.

[0003] In the process of teaching English, when teaching and writing in a standardized way on the letter format, it is necessary to draw four lines and three grids on the teaching board. Generally, this is done by manual writing, which makes it impossible to ensure the distance between the lines, and the drawing speed is slow, affecting the teaching progress. In order to improve the above problems, after searching, for example, a patent application number CN202020670733.7 disclosed an English teaching board, which includes a support box, support columns symmetrically fixed on the upper surface of the support box, a magnet fixed on the left surface of the support column, a drawing component magnetically attracted to the surface of the magnet, and a teaching board body fixed to the front surface of the support column. By fixing the chalk at equal intervals, it is convenient to draw four lines and three grids, which improves the drawing accuracy while avoiding repeated drawing that affects the teaching progress.

[0004] However, the drawing component of the above-mentioned English teaching board is relatively independent of the teaching board and is easily lost during use (for example, it is placed on the desk and covered by books after use, or is taken away by students to play with, etc.). In addition, when using the drawing component to manually draw four lines and three grids, it is difficult for teaching staff to ensure that the drawing is in a straight line, resulting in non-standard four lines and three grids, which is not conducive to the standardized writing teaching of letters. Therefore, an English teaching board is proposed to improve the above-mentioned problems. Utility Model Content

[0005] The purpose of this application is to provide an English teaching board to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present application provides the following technical solution: an English teaching board, comprising a board body, mounting seats being mounted on both left and right side ends of the board body, a horizontal rail being mounted vertically slidably between the two mounting seats, a driving assembly being mounted on the mounting seats for driving the horizontal rail to slide up and down, and a line drawing assembly being mounted horizontally slidably on the horizontal rail;

[0007] The line drawing assembly includes a moving block, a pressing plate, a clamping sleeve, a line drawing pen and a spring;

[0008] The moving block is horizontally slidably installed on the cross rail, the pressure plate is installed on the end of the moving block away from the plate body through the spring, the four clamping sleeves are equidistantly installed from top to bottom on the side of the pressure plate close to the moving block, the four drawing pens are correspondingly clamped on the inner side of the clamping sleeves, and the moving block is provided with a limiting through hole for the drawing pens to pass through horizontally.

[0009] As a further supplement to this solution, a guide column is vertically fixed to the end face of the pressure plate close to the moving block, a guide hole for inserting the guide column is provided on the moving block, and a handle is fixed to the end face of the pressure plate away from the moving block.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example: Reference Figure 1-5 The English teaching board shown in the figure includes a board body 1, and mounting seats 15 are installed on both the left and right ends of the board body 1. A horizontal rail 16 is vertically slidably installed between the two mounting seats 15, and a driving component for driving the horizontal rail 16 to slide up and down is installed on the mounting seat 15 to adjust the horizontal rail 16 to the position where the line is required to be drawn. Regarding the driving component, Figure 2 As shown, this embodiment adopts a driving motor 18 to cooperate with a threaded rod 19 to make the cross rail 16 slide up and down. Specifically, the driving motor 18 is installed on the top of the mounting seat 15, and the threaded rod 19 is vertically rotatably installed on the inner side of the mounting seat 15, and one end of the threaded rod 19 is coaxially fixed with the output shaft of the driving motor 18. A slider 17 is fixed at both ends of the cross rail 16, and a sliding groove 1 for sliding the slider 17 is vertically provided on the mounting seat 15, for the threaded rod 19 to thread through the slider 17, and a drawing component 20 is horizontally slidably installed on the cross rail 16.

[0032] Specifically, the line drawing assembly 20 includes a moving block 201, a pressing plate 203, a clamping sleeve 204, a line drawing pen 205 and a spring 207. The moving block 201 is horizontally slidably mounted on the cross rail 16. Specifically, as shown in FIG. Figure 2 and Figure 3As shown, a slider 202 is fixed to the top of the moving block 201, and a slide groove 2 is horizontally set at the lower end of the cross rail 16 for the slider 202 to slide horizontally. The pressure plate 203 is installed on the end of the moving block 201 away from the plate body 1 through a spring 207. Four clamping sleeves 204 are equidistantly installed from top to bottom on the side of the pressure plate 203 close to the moving block 201. The four drawing pens 205 are correspondingly connected to the inner side of the clamping sleeve 204, and in order to improve the stability of the clamping, a rubber ring is set on the inside of the clamping sleeve 204 to increase the friction between the clamping sleeve 204 and the drawing pen 205. A limiting through hole 206 is set on the moving block 201 for the drawing pen 205 to pass through horizontally.

[0033] When it is necessary to draw a line, the teaching staff can use an external controller to control the drive motor 18 to start, and the drive motor 18 drives the threaded rod 19 to rotate so that the slider 17 brings the cross rail 16 to the position where the line is needed to be drawn. Then the teaching staff only needs to manually press the pressure plate 203 and push it toward the blank side of the board body 1 to draw four lines, forming four lines and three grids for standard writing of letters. The set cross rail 16 can ensure that the four lines drawn are straight. When the pressure plate 203 is not pressed, the pressure plate 203 is under the elastic force of the spring 207 so that the drawing pen 205 does not contact the board body 1. Only when the pressure plate 203 is pressed and pushed at the same time can the line be drawn, so that the teaching staff can draw lines according to the actual drawing position required, which is more convenient to use. In addition, the line drawing component 20 is connected to the board body 1 and is not easy to lose.

[0034] In addition, the drawing pen 205 can be a cylindrical chalk, and when the drawing pen 205 is chalk, the board body 1 can be a conventional blackboard.

[0035] In order to prevent the drawing pen 205 from being easily distorted and broken when drawing lines, a guide column 208 is vertically fixed to the end face of the pressure plate 203 close to the moving block 201, and a guide hole 209 for the guide column 208 to be inserted is provided on the moving block 201. A handle 2010 is fixed to the end face of the pressure plate 203 away from the moving block 201. When drawing lines, the teaching staff manually holds the handle 2010 and presses it to move along the horizontal rail 16 to draw four lines and three grids.

[0036] In addition, the English teaching board also includes a T-shaped sliding sleeve 2 and a fixed seat 4, which are both fixedly connected to the wall. A T-shaped slide rail 3 is fixedly connected to the back of the board body 1, and the T-shaped slide rail 3 slides in conjunction with the T-shaped sliding sleeve 2. A screw rod 5 is connected to the middle of the back of the board body 1, and the screw rod 5 is vertically threaded from top to bottom through the fixed seat 4.

[0037] By coordinating the T-shaped sliding sleeve 2, the T-shaped sliding rail 3, the fixing seat 4 and the screw 5, the board body 1 can be moved up and down by rotating the screw 5, and the board body 1 can be adjusted to a comfortable height for writing, which is more convenient to use.

[0038] Among them, a second mounting block 7 is fixedly connected to the upper middle side of the back side of the plate body 1, and a connecting ring 8 is rotatably connected to the lower end of the second mounting block 7. The connecting ring 8 is sleeved on the top of the screw rod 5, and the connecting ring 8 and the screw rod 5 are fixed by a fixing bolt 9. The structure is simple and easy to install.

[0039] Furthermore, a first mounting block 6 is installed on the lower middle side of the back side of the plate body 1, and the screw 5 passes through the first mounting block 6 and is connected to the plate body 1 with an operating component. Specifically, the operating component includes gear 10, gear 2 11 and an adjusting knob 12. Gear 10 is coaxially fixed to the bottom of the screw 5, and the adjusting knob 12 is rotatably connected to the bottom of the plate body 1. Gear 2 11 is coaxially fixed to the adjusting knob 12 and meshes with gear 10. By rotating the adjusting knob 12, gear 10 rotates with gear 2 11, thereby causing the screw 5 to rotate, thereby realizing the up and down movement of the plate body 1. Among them, the diameter of gear 2 11 is larger than the diameter of gear 10, and the adjustment is faster.

[0040] In order to enhance the supporting strength of the plate body 1 , a supporting bar 13 is fixedly connected to the back of the plate body 1 , and the supporting bar 13 abuts against the wall.

[0041] As another improved implementation of this embodiment, the support bar 13 is movably connected to the end face away from the plate body 1 with a ball 14, and the ball 14 is in contact with the wall. During the up and down movement of the plate body 1, the ball 14 rolls and rubs against the wall to reduce the movement resistance.

[0042] The working principle of the utility model is as follows: the T-shaped sliding sleeve 2 and the fixing seat 4 are fixed to the wall by screws, the screw rod 5 is threaded through the fixing seat 4 from bottom to top, so that the top of the screw rod 5 is inserted into the inner side of the connecting ring 8, and the connecting ring 8 and the screw rod 5 are fixed by the fixing bolt 9. The adjusting knob 12 is turned to rotate the gear 10 with the gear 2 11, thereby rotating the screw rod 5 to realize the up and down movement of the board body 1, and the board body 1 is adjusted to a comfortable height for writing, which is more convenient to use. In the process of the board body 1 moving up and down, the ball 14 rolls and rubs against the wall, reducing the movement resistance.

[0043] When it is necessary to draw a line, the teaching staff can use an external controller to control the drive motor 18 to start, and the drive motor 18 drives the threaded rod 19 to rotate so that the slider 17 brings the horizontal rail 16 to the position where the line is needed to be drawn. Then the teaching staff only needs to manually press the pressure plate 203 and push it toward the blank side of the board body 1 to draw four lines, forming four lines and three grids for standard writing of letters. The set horizontal rail 16 can ensure that the four lines drawn are straight. When the pressure plate 203 is not pressed, the pressure plate 203 is under the action of the elastic force of the spring 207 so that the drawing pen 205 does not contact the board body 1. Only when the pressure plate 203 is pressed and pushed at the same time can the line be drawn, so that the teaching staff can draw lines according to the actual drawing position, which is more convenient to use.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
