Description

Technical Field

[0001] This utility model relates to the field of gypsum processing technology, and in particular to a gypsum board surface marking device. Background Technology

[0002] After being cut into strips, gypsum board can be used for interior decoration, generally referred to as gypsum lines. Gypsum board can be cut with a blade and a ruler, or it can be manually marked and then cut along the marked lines using a marble cutter. When manually marking lines, multiple measuring tools are needed to draw lines parallel to the edge of the gypsum board.

[0003] For example, a Chinese patent discloses a plasterboard marking auxiliary device (patent number: CN220680793U). By holding one of the clamping components and pulling it to one side, the connecting plate slides within the mounting block, adjusting the distance between the two clamping components. Rotating the rotating block then inserts the first threaded rod into the corresponding adjustment hole, fixing the connecting plate. Rotating the turntable sequentially moves the second threaded rod, causing the first clamping block to move towards the second clamping block, clamping and fixing both sides of the plasterboard. This fixes the marking board to the upper surface of the plasterboard, facilitating marking on the plasterboard surface and preventing displacement due to force during marking. This improves the marking effect of the plasterboard marking auxiliary device.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were found: As mentioned above, manual drawing of lines is required when using the solution. If there are uneven areas on the plasterboard, the lines may be bent, resulting in the lines not being straight. Utility Model Content

[0025] This application provides a gypsum board surface marking device, effectively solving the problem mentioned above where manual marking by workers is required, and lines may bend or become crooked if there are uneven areas on the gypsum board. The device uses a base, sliding plate, and connecting seat that move from left to right. The base and connecting seat drive the hub to slide on the surface of the gypsum board. A limiting block restricts the movement trajectory of the base and connecting seat to prevent one end from tilting up. The connecting seat drives the sliding seat to move from left to right, and the connecting seat drives the ruler and marking pen to move from left to right, marking the surface of the gypsum board. Even if the surface of the gypsum board is uneven, the lines can be drawn straight, thus ensuring that the lines are straight. The device is placed on one side of the plasterboard body. The first rotating disk is rotated counterclockwise, which drives the first threaded rod to rotate counterclockwise. The first threaded rod drives the sliding plate to move from bottom to top, and the sliding plate drives the base to move from bottom to top, so that the hub is locked with the bottom of the plasterboard body. Then, the scale is pulled to move the scale to the appropriate position. The second rotating disk is rotated counterclockwise, which drives the second threaded rod to rotate counterclockwise. The second threaded rod rotates in the sliding seat, so that the clamp block moves from top to bottom and locks the clamp block on the top of the scale. This allows for marking lines on plasterboard bodies of different lengths and thicknesses, thus facilitating marking on plasterboard bodies of different lengths and thicknesses.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problem mentioned above that manual marking is required during use, and if there are uneven areas on the gypsum board, the lines may be curved, resulting in non-straight lines. The overall idea is as follows: A gypsum board surface marking device includes a gypsum board body 11, and a marking mechanism is provided on the side wall of the gypsum board body 11. The marking mechanism includes a base 12, a sliding plate 13, a connecting seat 16, a sliding seat 17, a scale 18, a marking pen 23, a limiting block 24, a connecting rod 25, and a hub 26. The sliding plate 13 is fixedly installed on the top of the base 12 and slidably installed inside the connecting seat 16. The sliding seat 17 is fixedly installed on the side wall of the sliding seat 17. The scale 18 is slidably installed inside the sliding seat 17. The marking pen 23 is fixedly installed inside the scale 18. The limiting block 24... The connecting rods 25 are fixedly installed on the side wall of the connecting seat 16. There are six connecting rods 25, which are respectively fixedly installed on the side walls of the base 12 and the connecting seat 16. There are also six hubs 26, which are respectively fixedly installed on the side walls of the connecting rods 25. The base 12, the sliding plate 13 and the connecting seat 16 move from left to right. The base 12 and the connecting seat 16 drive the hubs 26 to slide on the surface of the gypsum board body 11. The limiting block 24 will limit the movement trajectory of the base 12 and the connecting seat 16 to prevent one end from tilting up. The connecting seat 16 drives the sliding seat 17 to move from left to right. The connecting seat 16 drives the scale 18 and the scribing pen 23 to move from left to right to scribing lines on the surface of the gypsum board body 11. Even if there are uneven areas on the surface of the gypsum board body 11, the lines can be drawn straight, thereby achieving the function of ensuring that the lines are straight.

[0028] A first threaded rod 14 is threaded inside the sliding plate 13. The first threaded rod 14 is rotatably mounted inside the connecting seat 16. A first rotating disk 15 is fixedly mounted on the side wall of the first threaded rod 14. A clamping block 19 is slidably mounted inside the sliding seat 17. A second threaded rod 21 is rotatably mounted on the top of the clamping block 19. A second rotating disk 22 is fixedly mounted on the side wall of the second threaded rod 21. When the device is placed on one side of the plasterboard body 11, the first rotating disk 15 is rotated counterclockwise. The first rotating disk 15 drives the first threaded rod 14 to rotate counterclockwise. The first threaded rod 14 drives the sliding plate 13 to move from bottom to top. The moving plate 13 drives the base 12 to move from bottom to top, so that the hub 26 is locked to the bottom of the plasterboard body 11. Then, the scale 18 is pulled to move the scale 18 to a suitable position. The second rotating disk 22 is rotated counterclockwise. The second rotating disk 22 drives the second threaded rod 21 to rotate counterclockwise. The second threaded rod 21 rotates in the thread inside the sliding seat 17, so that the clamp block 19 moves from top to bottom and locks the clamp block 19 on the top of the scale 18. This allows for marking lines on plasterboard bodies 11 of different lengths and thicknesses, thus facilitating marking lines on plasterboard bodies 11 of different lengths and thicknesses.

[0029] A handle 27 is fixedly installed on the side wall of the connecting seat 16, making it easy to hold the device for marking lines.

[0030] To address the problems existing in the prior art, this utility model provides a gypsum board surface marking device. The base 12, sliding plate 13, and connecting seat 16 move from left to right. The base 12 and connecting seat 16 drive the hub 26 to slide on the surface of the gypsum board body 11. A limiting block 24 restricts the movement trajectory of the base 12 and connecting seat 16 to prevent one end from tilting up. The connecting seat 16 drives the sliding seat 17 to move from left to right, and the connecting seat 16 drives the scale 18 and marking pen 23 to move from left to right, marking lines on the surface of the gypsum board body 11. Even if the surface of the gypsum board body 11 has uneven areas, the lines can be drawn straight, thus ensuring that the lines are straight. The device is placed on one side of the gypsum board body 11, and the first rotation is turned counterclockwise. The turntable 15 drives the first threaded rod 14 to rotate counterclockwise. The first threaded rod 14 drives the sliding plate 13 to move from bottom to top. The sliding plate 13 drives the base 12 to move from bottom to top, so that the hub 26 is locked to the bottom of the gypsum board body 11. Then, the scale 18 is pulled to move the scale 18 to a suitable position. The second turntable 22 is rotated counterclockwise. The second turntable 22 drives the second threaded rod 21 to rotate counterclockwise. The second threaded rod 21 rotates in the thread inside the sliding seat 17, so that the clamp block 19 moves from top to bottom and locks the clamp block 19 on the top of the scale 18. This allows for marking lines on gypsum board bodies 11 of different lengths and thicknesses, thus facilitating marking lines on gypsum board bodies 11 of different lengths and thicknesses.

[0031] Working principle:

[0032] First, place the device on one side of the plasterboard body 11, and rotate the first rotating disk 15 counterclockwise. The first rotating disk 15 drives the first threaded rod 14 to rotate counterclockwise, and the first threaded rod 14 drives the sliding plate 13 to move from bottom to top. The sliding plate 13 drives the base 12 to move from bottom to top, so that the hub 26 is locked with the bottom of the plasterboard body 11. Then pull the scale 18 to move the scale 18 to a suitable position, and rotate the second rotating disk 22 counterclockwise. The second rotating disk 22 drives the second threaded rod 21 to rotate counterclockwise. The second threaded rod 21 rotates in the thread inside the sliding seat 17, so that the clamp block 19 moves from top to bottom and locks the clamp block 19 on the top of the scale 18. This allows for marking lines on plasterboard bodies 11 of different lengths and thicknesses, thus facilitating marking lines on plasterboard bodies 11 of different lengths and thicknesses.

[0033] The second step is to push the handle 27 from left to right. The handle 27 drives the connecting seat 16 to pull from left to right. The connecting seat 16 drives the sliding plate 13 to move from left to right. The sliding plate 13 drives the base 12 to move from left to right. The connecting seat 16 and the base 12 drive the connecting rod 25 to move from left to right. The connecting rod 25 drives the hub 26 to move from left to right. The limiting block 24 limits the trajectory of the device's movement to prevent one end from tilting up, ensuring that the line is in a straight line, thereby achieving the function of ensuring that the line is in a straight line.

[0034] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
