[0001] This utility model relates to the field of architectural decoration marking technology, specifically an adjustable parallel line marking tool. Background Technology

[0002] In the process of building decoration and renovation, it is usually necessary to draw marking lines parallel to the existing structure. For example, parallel auxiliary lines need to be drawn when positioning the construction of cabinets, wardrobes, and plasterboard ceilings.

[0003] In existing construction positioning methods, when drawing parallel auxiliary lines, the distance between the desired line location and the wall is usually measured first, and then the line is drawn using a chalk line or a ruler. This method has low line accuracy, makes it difficult to ensure that the line trajectory remains parallel to the wall, and the line drawing operation is relatively complicated.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0009] The guide assembly includes a scale for marking the adjustment distance of the slider and a back plate located at one end of the scale for moving the scale along the extension direction of the wall.

[0010] Furthermore, the scale is fixedly connected to the back plate, and the scale and the back plate are perpendicular to each other;

[0011] The ruler has a scale bar on its upper side, which is used to mark the distance between the slider and the wall.

[0012] Furthermore, a rib is fixedly connected to one end of the scale on the back plate, and the rib is parallel to the scale.

[0013] A fixing block is fixedly connected to the side of the scale away from the back plate. One end of the fixing block relative to the scale is fixedly connected to the rib plate to reinforce the scale.

[0014] Furthermore, the slider is slidably sleeved on the outside of the scale, and a slot for clamping the marking pen is fixedly connected to one side of the rib plate.

[0015] The slot is made of a tough material.

[0016] Furthermore, a reading window is provided through one side of the scale bar on the slider;

[0017] A reading finger is fixedly connected to the upper end of the reading window, which is used to read the distance between the drawing pen and the wall;

[0018] The zero mark of the scale bar is located at the contact surface between the back panel and the wall.

[0019] Furthermore, a limiting block for limiting the slider is fixedly connected to the upper end of the scale and away from the back plate.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please refer to Figures 1-5. This utility model provides a technical solution:

[0033] An adjustable parallel line drawing tool, including a wall 100, and further including:

[0034] The marking assembly 2 includes a marking pen 23 for marking lines along the ground, and a slider 21 located on one side of the marking pen 23 for limiting the marking pen 23 and adjusting the distance between the marking position and the wall 100.

[0035] The guide assembly 1 includes a scale 13 for marking the adjustment distance of the slider 21, and a back plate 11 located at one end of the scale 13 for moving the scale 13 along the extension direction of the wall 100.

[0036] It should be noted that by placing one end of the back plate 11 against the side of the wall 100 and the lower end of the back plate 11 against the ground, sliding the slider 21 along the ruler 13 causes the drawing pen 23 to move until the distance between the drawing pen 23 and the wall 100 meets the distance between the parallel line to be drawn and the wall 100. Then, the back plate 11 is moved horizontally along the wall 100. The back plate 11 moves the slider 21 through the ruler 13. The slider 21 causes the drawing pen 23 to draw a straight line parallel to the wall 100 along the ground. This achieves the effect of simple drawing operation and the line trajectory always remaining parallel to the wall 100.

[0037] As an improvement, as shown in Figures 2-3, the scale 13 is fixedly connected to the back plate 11, and the scale 13 and the back plate 11 are perpendicular to each other.

[0038] The ruler 13 has a scale bar 131 on its upper side, which is used to mark the distance between the slider 21 and the wall 100.

[0039] Furthermore, as shown in Figure 2, a rib plate 12 is fixedly connected to one end of the back plate 11 located on the scale 13, and the rib plate 12 is parallel to the scale 13.

[0040] A fixing block 14 is fixedly connected to the side of the scale 13 and away from the back plate 11. One end of the fixing block 14 relative to the scale 13 is fixedly connected to the rib plate 12 to reinforce the scale 13 in conjunction with the rib plate 12.

[0041] Furthermore, as shown in Figures 2-5, the slider 21 is slidably sleeved on the outside of the ruler 13, and a slot 22 for clamping the marking pen 23 is fixedly connected to one side of the rib plate 12.

[0042] The slot component 22 is made of a tough material.

[0043] As shown in Figures 2 and 4, the slider 21 is provided with a reading window 211 through one side of the scale bar 131;

[0044] The upper end of the reading window 211 is fixedly connected to a reading finger 212, which is used to read the distance between the drawing pen 23 and the wall 100.

[0045] The zero mark of the scale bar 131 is located at the contact surface between the back plate 11 and the wall 100.

[0046] In addition, as shown in Figure 2, a limiting block 15 for limiting the slider 21 is fixedly connected to the upper end of the scale 13 and away from the back plate 11.

[0047] The inner wall of the slider 21 is limited by friction with the scale 13.

[0048] Furthermore, the back plate 11 is in contact with the ground;

[0049] The plane containing the lower end of the rib plate 12 is higher than the plane containing the lower end of the back plate 11.

[0050] It should be noted that, in the specific implementation process of this utility model, as shown in Figures 1-5, one end of the back plate 11 is placed against the side of the wall 100 and the lower end of the back plate 11 is placed against the ground. The slider 21 is slid along the ruler 13, and the slider 21 drives the marking pen 23 to move. The reading finger 212 is observed to indicate the reading on the scale bar 131. The slider 21 is stopped when the distance between the marking pen 23 and the wall 100 meets the distance between the parallel line to be drawn and the wall 100. At this time, the slider 21 makes the ruler 13 stay in a limited state through the friction between it and the ruler 13, so that parallel lines with different spacing can be drawn.

[0051] As shown in Figure 1-2, the back plate 11 is then moved horizontally along the wall 100. The back plate 11 moves the slider 21 through the ruler 13. The slider 21 drives the drawing pen 23 to draw a straight line parallel to the wall 100 along the ground, thus achieving the effect of simple drawing operation and the drawing trajectory always remaining parallel to the wall 100.
