It is mainly used for precise positioning and layout work in the early stage of building construction. Such devices can determine the positions on the ground through measurement according to the marked points on the design drawings, providing an accurate basis for subsequent construction work. Therefore, it can be seen that the existing marking devices basically meet people's usage requirements, but there are still the following problems.

[0003] When the operator is marking, it moves through the roller to discharge the powder in the powder chamber, thereby marking. However, since the size of the powder discharge port for discharging powder may be fixed, it may be impossible to adjust the width of the discharged powder. For this reason, we propose a marking device for building planning. Content of the Utility Model

[0004] The utility model provides a marking device for building planning. After the adjusting block moves, the adjusting block adjusts the size of the powder discharge port of the discharge pipe, thereby facilitating the adjustment of the marking width and improving the convenience of use for the operator.

[0023] In order to further understand the content, features and effects of the present utility model, the following embodiments are hereby exemplified and described in detail with reference to the accompanying drawings.

[0024] Embodiment:

[0025] Please refer to Figure 1 - Figure 6, a line marking device for building planning, including a push rod 1. A support pipe 3 is heat-melted and attached to the end of the push rod 1. A powder cavity 5 that is interconnected with a powder trough 8 is heat-melted and attached to the side of the support pipe 3 close to the powder trough 8. And a traction wheel 2 is arranged on one side of the support pipe 3. A rotating shaft 4 that penetrates the support pipe 3 is heat-melted and attached to the middle of the traction wheel 2. And a guiding wheel 6 is heat-melted and attached to the end of the rotating shaft 4. A powder trough 8 opened in the support pipe 3 is sleeved on the surface of the guiding wheel 6. And the powder trough 8 is rotationally connected to the guiding wheel 6. The powder trough 8 is communicated with a discharge pipe 7 heat-melted and attached to the support pipe 3. And an adjusting block 11 is embedded at the end of the discharge pipe 7. A bolt 13 is rotationally connected to the end of the adjusting block 11. A rotating block 15 is fixed to the side of the adjusting block 11 close to the bolt 13. And a rotating groove 16 opened on the bolt 13 is sleeved on the surface of the rotating block 15. And a thread groove 14 heat-melted and attached to the inner wall of the discharge pipe 7 is sleeved on the surface of the bolt 13. A screwing block 27 is heat-melted and attached to the end of the bolt 13. When the operator is marking a line, after the operator places the marking powder in the powder cavity 5 first, the operator pushes the push rod 1. The push rod 1 drives the rotating shaft 4 to move through the support pipe 3. The rotating shaft 4 drives the traction wheel 2 to move. When the traction wheel 2 moves on the ground, the traction wheel 2 rotates on the ground. The traction wheel 2 drives the guiding wheel 6 to rotate through the rotating shaft 4, so that the guiding wheel 6 rotates in the powder trough 8. When the guiding wheel 6 rotates in the powder trough 8, the wavy groove opened on the surface of the guiding wheel 6 draws the marking powder falling from the powder cavity 5 to the side where the powder trough 8 is interconnected with the discharge pipe 7, and discharges it through the discharge pipe 7. When the operator needs to adjust the width of the marked line, the operator first holds the surface of the screwing block 27 with the hand. Then the operator twists the screwing block 27. The screwing block 27 drives the bolt 13 to rotate. The bolt 13 is in threaded cooperation with the thread groove 14, so that the bolt 13 rotates. And when the bolt 13 rotates in threaded cooperation with the thread groove 14, the bolt 13 drives the rotating groove 16 to rotate on the surface of the rotating block 15, so that when the bolt 13 rotates, the bolt 13 cannot drive the adjusting block 11 to rotate, preventing the adjusting block 11 from interfering with the rotation of the bolt 13 after the bolt 13 is connected to the adjusting block 11. At the same time, when the bolt 13 is in threaded cooperation with the adjusting block 11, the bolt 13 pushes the adjusting block 11 to move, so that the adjusting block 11 slides horizontally in the discharge pipe 7, adjusting the size of the notch opened at the end opening of the discharge pipe 7, thereby adjusting the width of the marked line.

[0026] In other embodiments, the inner wall of the powder trough 8 is adhered to a baffle 10 penetrated by the guide wheel 6, and the end of one side of the baffle 10 is hot-melt-adhesively adhered to a lever 26 penetrating one side of the powder trough 8, and the end of the lever 26 is sleeved with a collar 19, and the collar 19 is elastically connected to the lever 26, and a traction groove 23 is opened in the middle of the lever 26, and a back plate 21 hot-melt-adhesively adhered to the inner wall of the collar 19 is inserted in the middle of the traction groove 23, and a slide rod 20 hot-melt-adhesively adhered to the inner wall of the traction groove 23 is penetrated in the middle of the back plate 21, and a spring 2 is wound around the surface of the slide rod 20. 2, the two ends of the spring 22 are respectively in contact between the surface of the support plate 21 and the inner wall of the traction groove 23, and the collar 19 and the support tube 3 are both hot-melt-bonded with a positioning rod 18 on one side, and the surface of the positioning rod 18 is provided with a positioning groove 25 on the outer wall of the support tube 3. When the operator needs to discharge the marking powder remaining in the powder tank 8, the operator first holds the hand on the surface of the collar 19, and then the operator pulls the collar 19, and when the collar 19 moves, the collar 19 drives the support plate 21 to move in the traction groove 23 When the plate 21 moves in the traction groove 23, the circular through hole in the middle of the plate 21 slides on the surface of the cylindrical slide bar 20, so that the slide bar 20 pulls the plate 21 to move, thereby improving the stability of the plate 21. When the plate 21 moves, the plate 21 squeezes the spring 22, causing the spring 22 to undergo elastic deformation. After the spring 22 undergoes elastic deformation, the spring 22 avoids the plate 21, causing the ring 19 to slide on the surface of the lever 26, and the ring 19 moves on the lever 26. When the surface slides, the collar 19 drives the positioning rod 18 to move, so that the positioning rod 18 moves out of the positioning groove 25. After the positioning rod 18 and the positioning groove 25 no longer fix the collar 19 and the support tube 3, the operator pulls the collar 19, and the collar 19 drives the baffle 10 to slide in the powder trough 8 through the lever 26, aligning the notch on the surface of the baffle 10 with the notch on the side of the support tube 3 connected to the powder trough 8, so that the dust in the powder trough 8 is discharged from the notch on the side of the baffle 10 and the support tube 3 connected to the powder trough 8.

[0027] In other embodiments, a guide groove 24 is opened on the outer wall of the baffle 10, and a plurality of traction blocks 17 hot-melt-bonded to the inner wall of the powder trough 8 are inserted in the middle of the guide groove 24. When the baffle 10 rotates in the powder trough 8, the guide groove 24 opened on the outer wall of the baffle 10 moves on the surface of the traction block 17, so that the guide groove 24 and the traction block 17 restrict the baffle 10, thereby preventing the baffle 10 from shaking when the baffle 10 rotates in the powder trough 8.

[0028] In other embodiments, a waist-shaped hole is formed in the middle of the adjusting block 11, and a cylindrical traction rod 12 is passed through the waist-shaped hole formed in the middle of the adjusting block 11. The traction rods 12 are all heat-melted and adhered to the inner wall of the discharge pipe 7. When the adjusting block 11 moves, the waist-shaped hole formed in the middle of the adjusting block 11 slides on the surface of the cylindrical traction rod 12, so that the traction rod 12 pulls the adjusting block 11, improving the stability of the movement of the adjusting block 11.

[0029] In other embodiments, a push block 9 is arranged at the opening of the discharge pipe 7, and the push block 9 is heat-melted and adhered to the guide wheel 6. When the guide wheel 6 rotates, the guide wheel 6 drives the push block 9 to rotate, so that the push block 9 stirs the powder collected in the powder trough 8, preventing the powder from accumulating in the powder trough 8 and improving the smoothness of discharging.
