Description

Technical Field

[0001] The utility model belongs to the field of engineering drawing, in particular to a plane drawing board for designing construction drawings. Background Art

[0002] When using existing construction drawing boards, two sets of sliding clamps are usually used to flatten the drawing paper, or pushpins are used to directly fix the drawings. However, before fixing, the drawings need to be kept horizontal and vertical on the construction drawing board so that the correctness of the drawing size can be guaranteed when drawing. However, when designing, the size of the drawing paper is sometimes not equal to that of the drawing board, which requires moving the drawing paper for design operations. It is not convenient to move the drawing paper due to the influence of clamps or pushpins.

[0003] A multifunctional drawing board for graphic design disclosed in a Chinese patent (CN219856597U) is used. When the drawing board needs to be fixed, the magnetic bar is pressed downward to cause the rubber pressure strip to contact the drawing paper to strengthen the restraining and fixing effect. When the drawing paper needs to be moved, the magnetic bar is moved upward. At this time, the rubber pressure strip moves upward, and the brush strip slides relative to the surface of the drawing paper, which will not affect the smooth movement of the drawing paper and can ensure the clarity of the pattern on the surface of the drawing paper. The initial elastic force of the reset spring is used to suspend and pull the rubber pressure strip, so that the rubber pressure strip is in a suspended state. When the magnetic bar does not slide down and squeeze, a gap can be left with the top surface of the drawing board, ensuring the smooth movement of the drawing paper and the clarity of the surface pattern.

[0004] In the prior art, the drawing needs to be smooth before clamping it so that the drawing fits the drawing board and the edge of the drawing is parallel to the drawing board when adjusting the drawing. However, the existing drawing board cannot ensure that the drawing fits. Utility Model Content

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A flat drawing board for construction drawing design comprises a picture frame, which is a hollow structure without a top. A drawing board is embedded in the upper surface of the picture frame, and a second slide groove is opened inside the drawing board along its width direction. Rectangular blocks are slidably connected in the second slide grooves, and rollers are rotatably connected between the rectangular blocks. Friction plates are evenly adhered to the rollers. When the rectangular blocks move in the second slide grooves, the rollers are driven to move synchronously in the picture frame along its width direction, so that the friction plates and the drawing board rub to generate static electricity, which has an adsorption effect on the drawings placed on the surface of the drawing board.

[0007] A cross bar is movably inserted in the drum, and both ends of the cross bar are fixedly connected in the rectangular block. One of the second sliding grooves runs through the side of the picture frame in the width direction so that the outer side of the rectangular block slidably connected therein is exposed, and a twist block protruding from the side of the picture frame is connected to the outer side of the exposed rectangular block.

[0008] A toothed plate is connected inside the picture frame along the width direction and above the second sliding groove, a gear is fixedly sleeved on one end of the roller, and the gear is meshed with the toothed plate.

[0009] An embedding groove is integrally formed on the upper surface of the picture frame, and a drawing board is embedded in the embedding groove, and a surface of the drawing board is level with a surface of the picture frame, and the drawing board is made of a material capable of absorbing static electricity.

[0010] A first slide groove is opened on the outer side of the drawing board along its length direction, a slider is slidably connected in the first slide groove, and the slider protrudes outside the first slide groove, a column is connected to the upper surface of the slider, and a ruler is connected between the columns.

[0011] The height of the column is greater than the thickness of the picture frame, and a groove is provided on the opposite side of the column where the part higher than the thickness of the picture frame is inserted into the groove. A spring is fixedly connected to the upper end of the groove, and the bottom of the spring contacts the ruler.

[0012] A rubber strip is pasted on the lower surface of the ruler, and scale values ​​are engraved on the upper surface of the ruler.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The present application divides the drawing board into two parts: a picture frame and a drawing board. The drawing board is made of a material that can temporarily store static electricity and is embedded in the picture frame. A roller is arranged to roll inside the picture frame. The friction plate connected to the roller is driven by the roller to rub the drawing board, thereby generating static electricity on the drawing board. When the drawing is attached to the drawing board, it will be tightly adsorbed due to the static electricity. Therefore, the drawing will not shake randomly during the process of adjusting the drawing, which is conducive to adjusting the horizontality and verticality of the drawing.

[0015] (2) Furthermore, the electrostatically adsorbed drawing will not be displaced even if the draftsman touches the drawing with his wrist during the drawing process, thereby ensuring the continuity of the drawing and preventing the line segments from being crooked or dotted lines from being generated due to the displacement of the drawing caused by the touching of the drawing.

[0016] (3) At the same time, a ruler is slidably connected to the drawing frame of the present application. The ruler can press down the adjusted drawing to ensure that the drawing is fixed after adjustment and will not easily shift. The ruler is provided with a scale to facilitate the use of the ruler as a T-ruler or to make it easier to draw by combining the T-ruler and the ruler. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0028] See also Figure 1-4A plane drawing board for construction drawing design includes a picture frame 100, and a drawing board 105 is embedded on the upper surface of the picture frame 100. The picture frame 100 and the drawing board 105 together constitute a plane drawing board, and the picture frame 100 is set to a hollow structure, which is convenient for installing other components inside it, so as to realize the improvement of the present application. A second slide groove 100b is opened inside the drawing board 105 along its width direction, and a rectangular block is slidably connected in the second slide groove 100b. A roller 103 is rotatably connected between the rectangular blocks, and a friction plate 103a is evenly adhered to the roller 103. When the rectangular block moves in the second slide groove 100b, it drives the roller 103 to move synchronously in the picture frame 100 along its width direction, so that the friction plate 103a and the drawing board 105 rub to generate static electricity, which has an adsorption effect on the drawings placed on the surface of the drawing board 105.

[0029] exist Figure 5 and Figure 6 In the figure, a cross bar 103c is movably inserted in the roller 103, so that the roller 103 can rotate on the cross bar 103c, so that the roller 103 can reciprocate and rub the drawing board 105 to generate static electricity. The two ends of the cross bar 103c are fixedly connected in the rectangular block. The rolling of the roller 103 is mainly generated by the movement of the rectangular block slidably connected in one of the second slide grooves 100b, and the rectangular block needs external force to move in the second slide groove 100b. Therefore, one of the second slide grooves 100b is passed through the side of the picture frame 100 in the width direction so that the outer side of the rectangular block slidably connected therein is exposed, and a twist block 103b protruding from the side of the picture frame 100 is connected to the outer side of the exposed rectangular block. Manually pushing and pulling the twist block 103b drives the rectangular block to move.

[0030] exist Figure 5 and Figure 6 In the embodiment, since the friction plate 103a is installed on the roller 103 in a surrounding and equidistant manner, the friction force of the friction plate 103a on the drawing board 105 when the roller 103 rolls is greater than the friction force of the roller 103 on the drawing board 105 when the roller 103 is static. Therefore, the present application chooses to adopt the rolling motion of the roller 103, and a tooth plate 104 is connected inside the picture frame 100 along the width direction and above the second slide groove 100b. A gear 103d is fixedly sleeved on one end of the roller 103, and the gear 103d is meshed with the tooth plate 104. When the roller 103 moves, the gear 103d fixedly sleeved on the roller 103 will move on the tooth plate 104. Due to the meshing effect, the gear 103d rotates, and the gear 103d synchronously drives the roller 103 to rotate when it rotates.

[0031] exist Figure 3In the drawing, a groove 100c is integrally formed on the upper surface of the picture frame 100, and the drawing board 105 is embedded in the groove 100c. The groove 100c mainly has an embedding and supporting function for the drawing board 105, so that the four sides of the drawing board 105 can be in contact with the picture frame 100, which is beneficial to sharing the pressure when painting. In order to ensure the use process, the surface of the drawing board 105 is level with the surface of the picture frame 100. The drawing board 105 is made of a material that can absorb static electricity, which is beneficial to temporarily store static electricity to absorb the drawings.

[0032] exist Figure 1-2 In the drawing board 105, a first slide groove 100a is provided on the outside along the length direction thereof, a slider 101 is slidably connected in the first slide groove 100a, and the slider 101 protrudes outside the first slide groove 100a, a column 101a is connected to the upper surface of the slider 101, and a weight 102 is connected between the columns 101a, and the weight 102 can press the drawing to ensure that the drawing is fixed after adjustment. Further, in order to ensure that the weight 102 can press the drawing, the height of the above-mentioned column 101a is greater than the thickness of the picture frame 100, and the column 101a is higher than the thickness of the picture frame 100. The opposite side A groove is provided, and a weight 102 is inserted into the groove. A spring is fixedly connected to the upper end of the groove, and the bottom of the spring contacts the weight 102. The spring is used to press the weight 102 onto the drawing. In order to ensure the fit between the weight 102 and the drawing, a rubber strip is pasted on the lower surface of the weight 102. At the same time, the weight 102 can slide on the drawing board 105 through the slider 101 and the first slide groove 100a, so that the weight 102 can be used directly as a drawing measuring tool. At the same time, it can also be used in conjunction with the T-shaped ruler used in the drawing as the x and y axes. Therefore, the upper surface of the weight 102 is engraved with scale values.
