Description

Technical Field

[0001] This utility model relates to the technical field of drafting machines or drawing devices that maintain parallelism, and more particularly to an English line marker. Background Technology

[0002] With the continuous development of education in my country, teaching methods for various subjects have greatly improved, especially the improvement of equipment for English teaching, such as English line markers. Currently, most English line markers use two clamps to hold four pieces of chalk for marking lines. However, since the distance between the four pieces of chalk within the clamps is fixed, it's inconvenient for teachers to adjust the spacing when teaching English characters of varying sizes. This makes it difficult to draw lines with different spacing, hindering the adjustment of the chalk spacing based on the size of the English characters and thus hindering English writing instruction. Therefore, a new English line marker is needed to solve these problems. Utility Model Content

[0003] The purpose of this invention is to solve the problem in the prior art that it is inconvenient to adjust the spacing between four chalks according to the size of the English writing, and thus to propose an English line drawing device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An English line marker, comprising a mounting plate, a groove is laterally formed inside the lower end of the mounting plate, a slide rod is laterally fixed inside the groove, four sliders are slidably arranged on the surface of the slide rod, and the spacing between the four sliders is the same, a round rod is fixedly arranged at the rear end of each of the four sliders, a round plate is fixedly arranged at the outer end of each of the four round rods, and a ring is rotatably sleeved on the surface of each of the four round rods, and the ring, the round plate and the round rod are located at the rear end of the mounting plate.

[0005] Furthermore, a movable plate is movably provided at the rear end of the mounting plate. The end face of the movable plate has four inclined grooves, four round rods and four rings are respectively located in the four inclined grooves, and the four round plates are all located outside the movable plate. A threaded block is fixedly provided at one end of the top of the movable plate, and a movable block is fixedly provided at the other end of the top of the movable plate.

[0006] Furthermore, a first fixing block is fixedly installed at both the top and bottom ends of one rear end of the mounting plate, and a threaded rod is vertically rotatably installed between the two first fixing blocks. A turntable is fixedly installed at the top of the threaded rod, and the turntable is located above the mounting plate. The threaded block is threaded onto the threaded rod. A second fixing block is fixedly installed at both the top and bottom ends of the other rear end of the mounting plate, and a moving rod is vertically fixed between the two second fixing blocks. The moving block is slidably installed on the moving rod. A handle is fixedly connected between the centers of the two rear ends of the mounting plate, and the handle is located outside the moving plate.

[0007] Furthermore, each of the four sliders has a vertically fixed plate at its front end, and the vertical plate is located at the front end of the mounting plate. Each of the four vertical plates has a first clamping plate fixed at its bottom end, and each of the four vertical plates has a fixed plate fixed at its top end. Each of the four fixed plates has a sliding rod vertically slidingly mounted inside its center end face, and each of the four sliding rods has a second clamping plate fixed at its bottom end, and the second clamping plate is located between the fixed plate and the first clamping plate.

[0008] Furthermore, a spring is fixedly connected between the second clamping plate and the fixed plate, and the spring is sleeved on the sliding rod.

A rectangular groove is opened horizontally inside each of the four rectangular blocks, and a rectangular rod is slidably installed horizontally inside the four rectangular grooves. Handles are fixedly connected to the top of both sides of the rectangular rods, and the handles are located above the four rectangular blocks.

[0010] The beneficial effects of this utility model are:

[0011] 1. In this utility model, rotating the turntable facilitates the rotation of the threaded rod, which in turn facilitates the up-and-down movement of the threaded block. The up-and-down movement of the threaded block facilitates the up-and-down movement of the moving plate, which in turn facilitates the convergence and divergence of the four round rods and four rings within the four inclined slots. The convergence and divergence of the four round rods facilitates the movement of the four sliders closer to or further away from each other, thereby facilitating the adjustment of the spacing between the four chalks at the front ends of the four sliders. This allows for the drawing of lines with different spacings, making it convenient to adjust the spacing between the four chalks according to the size of the English writing, thus facilitating English writing instruction.

[0012] 2. In this utility model, pulling the handle facilitates the upward movement of the rectangular rod, which in turn facilitates the upward movement of the four rectangular blocks. The upward movement of the four rectangular blocks then facilitates the upward movement of the four sliding rods, which in turn facilitates the upward movement of the four second clamping plates, compressing the four springs. The upward movement of the four second clamping plates away from the four chalks makes it easy to remove the four chalks and replace them, thereby improving the efficiency of line drawing.

The movement of the round rod 5 facilitates the movement of the slider 4 on the slide bar 3, thereby facilitating the movement of the slider 4 within the groove 2, and ultimately, facilitating the horizontal movement of the slider 4 within the lower end of the mounting plate 1.

[0021] Furthermore, a movable plate 8 is movably provided at the rear end of the mounting plate 1. Four inclined grooves 9 are formed on the end face of the movable plate 8. Four round rods 5 and four round rings 7 are respectively located within the four inclined grooves 9. Four round plates 6 are all located outside the movable plate 8. A threaded block 10 is fixedly provided at one end of the top of the movable plate 8, and a movable block 11 is fixedly provided at the other end of the top of the movable plate 8. Preferably, the movable plate 8 facilitates the lateral movement of the slider 4 within the lower end of the mounting plate 1, and the inclined grooves 9 facilitate the movement of the round rings 7 and round rods 5 closer to or further away from each other within the movable plate 8. The movable plate 8 is positioned within the inclined groove 9 by a circular plate 6, which prevents the circular ring 7 and circular rod 5 from detaching from them. A threaded block 10 facilitates the up-and-down movement of the movable plate 8 at the rear end of the mounting plate 1, allowing the circular ring 7 and circular rod 5 to move closer to or further away. This, in turn, facilitates the lateral movement of the four sliders 4 within the lower end of the mounting plate 1. A movable block 11 provides stable support for the up-and-down movement of the movable plate 8, thereby improving its stability. Furthermore, first fixing blocks 12 are fixedly installed at both the top and bottom ends of one rear end of the mounting plate 1.

A second fixing block 15 facilitates the vertical fixation of a movable rod 16 on the other side of the rear end of the mounting plate 1. The movable rod 16 facilitates the up-and-down movement of the movable block 11 on the other side of the rear end of the mounting plate 1. A handle 17 facilitates the lifting of the entire mounting plate 1, thus making it convenient for teachers to use the English line marker. Rotating the turntable 14 facilitates the rotation of the threaded rod 13 between the two first fixing blocks 12. The rotation facilitates the up-and-down movement of the threaded block 10 between the two first fixed blocks 12. The up-and-down movement of the threaded block 10 facilitates the up-and-down movement of the moving plate 8. The up-and-down movement of the moving plate 8 facilitates the up-and-down movement of the moving block 11 on the moving rod 16, which in turn facilitates the up-and-down movement of the moving block 11 between the two second fixed blocks 15, thereby facilitating the stable up-and-down movement of the moving plate 8.

[0022] Furthermore, each of the four sliders 4 has a vertically fixed vertical plate 18 at its front end, and the vertical plate 18 is located at the front end of the mounting plate 1. Each of the four vertical plates 18 has a first clamping plate 19 fixed at its bottom end, and each of the four vertical plates 18 has a fixed fixing plate 20 fixed at its top end. Each of the four fixed fixing plates 20 has a sliding rod 21 vertically slidably mounted within its center end face, and each of the four sliding rods 21 has a second clamping plate 22 fixedly mounted at its bottom, with the second clamping plate 22 located between the fixed plate 20 and the first clamping plate 19. Preferably, the vertical plates 18 facilitate the mounting of the fixed plate 20 and the first clamping plate 19 on the upper and lower sides of the front end of the slider 4, respectively. The first clamping plate 19 facilitates the placement of chalk 24 at the front end of the slider 4. The fixed plate 20 facilitates the vertical sliding mounting of the sliding rod 21 within it, and the sliding rod 21 facilitates the placement of the second clamping plate 22 between the fixed plate 20 and the first clamping plate 19. The second clamping plate 22 is provided to easily clamp the chalk 24 onto the first clamping plate 19. By pulling the sliding rod 21 to move up and down within the fixed plate 20, the second clamping plate 22 can be easily moved up and down on the first clamping plate 19, thus making it convenient to clamp and fix chalk 24 of different sizes.

[0023] Furthermore, a spring 23 is fixedly connected between the second clamping plate 22 and the fixed plate 20, and the spring 23 is sleeved on the sliding rod 21. Chalk 24 is clamped between each of the four second clamping plates 22 and the four first clamping plates 19, and the inner end faces of the second clamping plates 22 and the first clamping plates 19 are all arc-shaped. Preferably, the second clamping plates 22 facilitate the sleeved spring 23 on the sliding rod 21, the spring 23 facilitates the pressure for the up and down movement of the second clamping plates 22, the chalk 24 facilitates drawing lines on the blackboard, the upward movement of the second clamping plates 22 compresses the spring 23 to facilitate the removal of the chalk 24, and the rebound of the spring 23 causes the second clamping plates 22 to move downward to fix the chalk 24, thereby facilitating the replacement of the chalk 24 between the second clamping plates 22 and the first clamping plates 19.

[0024] Furthermore, a rectangular block 25 is fixedly installed on the top of each of the four sliding rods 21, and the rectangular blocks 25 are located above the fixed plate 20. A rectangular groove 26 is horizontally opened inside each of the four rectangular blocks 25, and a rectangular rod 27 is horizontally slidably installed inside the four rectangular grooves 26. Handles 28 are fixedly connected to the top of both sides of the rectangular rod 27, and the handles 28 are located above the four rectangular blocks 25. Preferably, the rectangular blocks 25 are provided to limit the vertical sliding distance of the sliding rods 21, the rectangular grooves 26 are provided to facilitate the horizontal sliding of the rectangular rod 27 inside the rectangular blocks 25, the rectangular rod 27 is provided to facilitate the simultaneous movement of the four rectangular blocks 25, the handles 28 are provided to facilitate the vertical movement of the rectangular rod 27, the vertical movement of the rectangular rod 27 facilitates the simultaneous vertical movement of the four rectangular blocks 25 through the rectangular grooves 26, and the simultaneous vertical movement of the four rectangular blocks 25 facilitates the simultaneous vertical movement of the four second clamping plates 22 through the sliding rods 21, thereby facilitating the simultaneous replacement of the four chalks 24 and improving the efficiency of chalk marking.

[0025] In this invention, during use, pulling the handle 28 moves the rectangular rod 27 upward. The upward movement of the rectangular rod 27, via the rectangular groove 26, moves the four rectangular blocks 25 upward simultaneously. The upward movement of the four rectangular blocks 25 moves the four sliding rods 21 upward simultaneously. The upward movement of the four sliding rods 21 moves the four second clamping plates 22 upward, compressing the four springs 23. Then, the four pieces of chalk 24 are placed on the four first clamping plates 19 respectively. Releasing the handle 26 causes the four second clamping plates 19 to move downward under the rebound force of the four springs 23, thus conveniently clamping and fixing the four pieces of chalk 24 between the four second clamping plates 22 and the four first clamping plates 19. When it is necessary to adjust the spacing between the four pieces of chalk 24... When adjusting the spacing, the turntable 14 drives the threaded rod 13 to rotate between the two first fixed blocks 12. The rotation of the threaded rod 13 drives the threaded block 10 to move up and down between the two first fixed blocks 12. The up and down movement of the threaded block 10 drives the moving plate 8 to move up and down at the rear end of the mounting plate 1. The up and down movement of the moving plate 8 drives the four rings 7 to move closer or further away through the four inclined grooves 9. In turn, the four round rods 5 drive the four sliders 4 to move laterally closer or further away on the slide rod 3, so as to facilitate the adjustment of the spacing between the four chalks 24 at the front end of the four sliders 4. After the adjustment is completed, the handle 17 is removed so that the four chalks 24 can draw English lines on the blackboard, thus facilitating the teaching of English writing.
