Description

Technical Field

[0001] The utility model relates to the field of drawing boards, in particular to a portable drawing board component. Background Art

[0002] When drawing architectural drawings by hand, traditional drawing boards and T-squares are usually used. Figure 4 As shown, during the drawing process, the draftsman's left hand must always hold the T-square to ensure that the ruler head is close to the left side of the drawing board in order to draw a horizontal line. When drawing a plumb line, one of the right-angled sides of the triangle ruler must be aligned with the T-square. In other words, the draftsman must fix both the triangle ruler and the T-square at the same time, which makes the drawing operation very inconvenient.

[0003] The existing drawing board and T-square assembly mainly have the following shortcomings:

[0004] 1. When drawing lines using a traditional drawing board, T-square and set square, the draftsman needs to use both hands to coordinate, and the probability of drawing oblique lines is high;

[0005] 2. The drawing board, T-square and triangle are three independent tools, which need to be carried separately. Therefore, it is inconvenient to carry. In particular, the T-square has a special structure. It is easy to collide with others or objects when holding it alone, which is unsafe.

[0006] 3. During the hand-drawing process, the T-square and the triangle need to be adjusted back and forth. Due to the lack of guide and limit structure, the adjustment efficiency is low and the stability after adjustment is poor;

[0007] 4. There is no protection on the left end of the drawing board. The head of the T-square ruler has been rubbing and colliding with the left end of the drawing board for a long time. After long-term use, it is not smooth and needs to be improved. Utility Model Content

[0009] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a portable drawing board assembly, including: a drawing board, a triangle and a T-ruler, the T-ruler includes a ruler head and a ruler body, the ruler body is horizontally arranged on the front of the drawing board, the ruler head is arranged at one end of the ruler body, the drawing board is concavely provided with a longitudinal slide groove corresponding to the ruler head, the ruler head can be slidably arranged in the longitudinal slide groove, the top of the ruler body is concavely provided with a transverse slide groove, and the bottom of the triangle can be transversely arranged in the transverse slide groove.

[0010] In a preferred embodiment of the present invention, the longitudinal slide groove is located at the left end of the front side of the drawing board.

[0011] In a preferred embodiment of the present invention, a bead contacting the side wall of the longitudinal slide groove is arranged at the front end of the ruler head.

[0012] In a preferred embodiment of the present invention, arc-shaped positioning grooves corresponding to the bumping balls are arranged at intervals along the length direction of the side wall of the longitudinal slide groove.

[0013] In a preferred embodiment of the present invention, the front side of the ruler body is concavely provided with a waist hole connected to the transverse slide groove, and a screw connected to the triangle plate is provided in the waist hole.

[0014] In a preferred embodiment of the present invention, the triangular plate is provided with threaded holes corresponding to the screws.

[0015] In a preferred embodiment of the present invention, the ruler head and ruler body adopt an integrated structure.

[0024] like Figure 1 and Figure 3 The portable drawing board assembly shown includes: a drawing board 1, a triangle 3 and a T-rule 2. The T-rule 2 includes a ruler head 21 and a ruler body 22. The ruler body 22 is arranged horizontally on the front of the drawing board 1, which is conducive to drawing horizontal lines. The ruler head 21 is arranged at one end of the ruler body 22. In this embodiment, the ruler head 21 and the ruler body 22 adopt an integrated structure, which is stable and avoids the separation problem of the ruler head 21 and the ruler body 22. The use process is more reliable. The ruler head 21 and the ruler body 22 can be formed in one step by injection molding, which is convenient for production, or they can be made of steel plates.

[0025] The drawing board 1 is provided with a concave longitudinal slot 11 corresponding to the ruler head 21, and the ruler head 21 is slidably arranged in the longitudinal slot 11. The ruler head 21 is guided by the longitudinal slot 11 to achieve rapid adjustment of the T-rule 2, and it is convenient to draw a horizontal line at any longitudinal position. In this embodiment, the longitudinal slot 11 is located at the left end of the front of the drawing board 1, which is in line with the usage habits and avoids the wear of the left end of the drawing board 1.

[0026] like Figure 3 As shown, the front end of the ruler head 21 is provided with a bumping ball 5 in contact with the side wall of the longitudinal slide groove 11, which increases the damping of the ruler head 21 sliding adjustment in the longitudinal slide groove 11 and improves the position stability after sliding adjustment. In addition, the side wall of the longitudinal slide groove 11 is provided with arc-shaped positioning grooves corresponding to the bumping balls 5 at intervals along its length direction. The arc-shaped positioning grooves can realize accurate positioning of the bumping balls 5, improve the accuracy and stability of the ruler head 21 adjustment, and are suitable for drawing multiple fixed position horizontal lines.

[0027] like Figure 2 As shown, a transverse groove 24 is provided inwardly at the top of the ruler body 22, and the bottom of the triangle plate 3 can be laterally moved in the transverse groove 24, and the side of the triangle plate 3 perpendicular to the ruler body 22 is used to quickly draw a plumb line.

[0028] A waist hole 23 connected to the horizontal slide groove 24 is concavely arranged on the front side of the ruler body 22, and a screw 4 connected to the triangle plate 3 is arranged in the waist hole 23. In the present embodiment, a threaded hole corresponding to the screw 4 is arranged on the triangle plate 3, so that the screw 4 can be conveniently tightened and loosened, so that the triangle plate 3 can be adjusted and fixed at any horizontal position. The operation is simple, and the plumb line can be drawn at any horizontal position, thereby improving the convenience and accuracy of drawing the plumb line.
