Description

Technical Field

[0001] The present invention relates to the technical field of interior design, and specifically relates to an interior design drawing board with an axonometric auxiliary function and a using method thereof. Background Art

[0002] Interior design is a design work that combines engineering technology and art. According to the nature of the building itself and the surrounding scene, corresponding technical means are used to create a reasonable and comfortable interior environment. An interior design drawing board is required during interior design. There are still some defects in the existing interior design drawing boards when in use;

[0003] For example, the publication number CN115257224A discloses a drawing stand for interior design. By setting a hydraulic rod, while it makes a reciprocating motion, it can squeeze and restore an air storage sleeve. On the one hand, not only can the blowing cover blow out gas through the first air exchange pipe, the first air groove and the air inlet pipe to blow off rubber scraps, but also the suction cover can absorb the rubber scraps through negative pressure and then collect them through a filter screen; on the other hand, by closing the control valve, the gas can be blown out from the first air drying cover and the second air drying cover to accelerate the drying rate of the ink of the colored pen. Finally, it can also drive the rocker to make a reciprocating swinging motion at the same time to blow air at the painter, which can effectively achieve the purpose of improving the poor air circulation in the room and helping the painter to cool down by blowing air;

[0004] Although the above device can make improvements in terms of support and ink drying, it does not make improvements in terms of drawing. It cannot assist in drawing an isometric drawing, and during the drawing process, it cannot draw isometric oblique lines of different lengths and isometric ellipses of different sizes. When the existing interior design drawing board is in use, when adjusting the lengths of the major axis and minor axis of the isometric ellipse, it cannot ensure that the ratio of the major axis to the minor axis of the isometric ellipse remains constant all the time, and the stability is insufficient.

[0012] As a preferred solution of an indoor design drawing board with an axonometric auxiliary function according to the present invention, the following is provided: the clamping assembly includes a fixed shaft fixedly installed on the surface of the middle plate.

[0013] As a preferred solution of an indoor design drawing board with an axonometric auxiliary function according to the present invention, the following is provided: the angle adjuster includes fixed sleeves fixedly installed on the upper and lower sides at the left end of the drawing board.

A pressing bolt is threadedly connected to the inside of the top end of the rotating sleeve. The rotating rod is slidably installed inside the rotating sleeve, and the position of the right end of the connecting rod corresponds to the position of the sliding rod.

[0014] As a preferred solution of an indoor design drawing board with an axonometric auxiliary function according to the present invention, the following is provided: the longitudinal section of the scale plate is a regular hexagon, and three wire grooves are equally angularly distributed on the surface of the scale plate, and the ends of the wire grooves and adjacent wire grooves are interconnected.

[0015] A method for using an indoor design drawing board with an axonometric auxiliary function includes the following steps:

[0016] S1: Fix the drawing paper through the adhesive layer on the drawing board. When drawing an axonometric drawing, pull the scale plate to separate the second magnetic block on the left side of the scale plate from the first magnetic block, and use the three wire grooves equally angularly distributed on the surface of the scale plate to draw an axonometric rectangle or cuboid;

[0017] S2: Support the upper and lower sides of the middle plate through the telescopic assembly on the drawing board. By changing the lengths of the telescopic assemblies on the upper and lower sides of the middle plate, the middle plate and the isometric ellipse gauge can adjust their own angles and positions on the drawing board, thereby realizing the function of drawing ellipses at different angles and different positions;

[0018] S3: After adjusting the elongation of the telescopic components on the upper and lower sides, the angle of the left half of the angle adjuster can be adjusted through the angle adjuster, so that the right half of the angle adjuster abuts against the telescopic components on the upper and lower sides. The user can move the angle adjuster to enable the telescopic components to move horizontally at a specific inclination angle, so that the tilted middle plate and the isometric ellipsograph can move horizontally, and then draw an isometric ellipse at a specific position on the drawing paper.

[0019] S4: Through the synchronous adjustment component on the outside of the isometric ellipsograph, the device can adjust the major axis and minor axis of the isometric ellipse drawn by the isometric ellipsograph in a ratio of 1.732:1, so that the device can draw isometric ellipses of different sizes. During the drawing process, the clamping component enables the isometric ellipsograph to move horizontally left and right after adjustment, thus ensuring the stability of the isometric ellipse drawing. The drawing paper is made translucent through the lamp panel, and the angle scale lines on the lamp panel are used to adjust the angle of the isometric ellipsograph, so as to accurately adjust the angle of the isometric ellipse.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. By providing the ruler plate and the wire groove, the device can draw an isometric rectangle or cuboid. After drawing one side of the rectangle, one of the wire grooves can be used as a reference line to draw the remaining edges of the figure, thus realizing the function of drawing an isometric rectangle and cuboid, improving the functionality of the device, making improvements in auxiliary drawing, and solving the problem that the existing drawing board has added functions but has not made improvements in painting.

[0022] 2. Through the telescopic components on the device in cooperation with the rotatable middle plate, the angle of the middle plate can be adjusted during the elongation or shortening of the telescopic components on the upper and lower sides, so that the device can draw isometric ellipses on different faces of the cuboid. Rotate the isometric ellipsograph clockwise by 90°, counterclockwise by 30°, and clockwise by 30° respectively to draw the isometric ellipses on the top surface, left side surface, and right side surface of the cuboid, improving the drawing effect of the device. Through the provided angle adjuster, after the isometric ellipsograph is rotated clockwise by 90°, counterclockwise by 30°, and clockwise by 30°, the right end of the connecting rod is adjusted to correspond to the position of the sliding rod. At this time, when the sliding rod is moved, it can drive the isometric ellipsograph to move horizontally to the right, so that the device can draw isometric ellipses at different positions.

[0023] 3. Through the isometric ellipse gauge and the synchronous adjustment component, the device can make the synchronous wheels at various positions rotate synchronously through the rotation of the first synchronous wheel, so that the ellipse drawn by the isometric ellipse gauge can keep the major axis and the minor axis synchronously elongating and shortening in a specific ratio. Furthermore, during the process of drawing the ellipse, the angle between the line connecting the endpoints of the major axis and the minor axis and the major axis can always be kept at 30°. This enables the device to not only draw isometric ellipses but also draw isometric ellipses of different sizes, facilitating the subsequent drawing of the isometric drawing of a cylinder, improving the convenience of using the device, solving the defect that the existing indoor design drawing board cannot draw isometric ellipses of different sizes during use, and the device has the advantage of a higher degree of adjustability.

[0024] 4. Through the clamping component provided, after the isometric ellipse gauge is adjusted, it can be fixed by the mutual engagement of the first damping block and the second damping block, thereby enabling the device to fix the lengths of the major axis and the minor axis of the isometric ellipse gauge after adjustment, improving the overall stability of the device.

[0039] In order to make the purpose, technical solution, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] As Figures 1-9As shown, an interior design drawing board with axial auxiliary function comprises a drawing board 1, an adhesive layer 2 is arranged around the front surface of the drawing board 1, a light board 3 is installed at the lower left of the front surface of the drawing board 1, and the surface of the light board 3 is provided with angle scale lines 4, the light board 3 can illuminate the drawing paper attached to the surface of the adhesive layer 2, so that the drawing paper is light-transmitting, and the angle scale lines 4 are used as a comparison at this time, so as to facilitate the subsequent drawing of isometric ellipses on different faces of the surface of the cube, telescopic components 5 are arranged on the upper and lower sides of the drawing board 1, a middle plate 6 is rotatably installed between the telescopic components 5 and the adjacent telescopic components 5, and the telescopic extension of the telescopic components 5 and the adjacent telescopic components 5 can adjust the angle of the middle plate 6 so as to draw figures at different angles subsequently, an isometric ellipsometer 7 is installed at the front end of the middle plate 6, a handle 8 is fixedly connected to the middle of the middle plate 6, a clamping component 11 is arranged on the side of the isometric ellipsometer 7, and a synchronous adjustment component 9 is rotatably installed on the surface of the middle plate 6, The synchronous adjustment component 9 enables the ellipse drawn by the isometric ellipsometer 7 to keep the major and minor axes shortened or lengthened in a specific ratio, so that the device can draw isometric ellipses of different sizes. An angle adjuster 12 is installed on the left side of the telescopic component 5. The angle adjuster 12 can cooperate with the telescopic component 5 so that the angles of the telescopic component 5 and the adjacent telescopic component 5 can remain unchanged after the adjustment is completed, and the water surface can move left and right, thereby improving the overall stability of the device. A first magnetic block 13 is fixedly connected to the right side of the drawing board 1, and a second magnetic block 14 is adsorbed on the right side of the first magnetic block 13. A ruler 15 is fixedly connected to the right side of the second magnetic block 14, and wire grooves 16 are provided at equal angles on the surface of the ruler 15. By setting the ruler 15 and the wire grooves 16, the device can use the wire grooves 16 on the ruler 15 to draw isometric cubes and rectangles when in use. The first magnetic block 13 and the second magnetic block 14 enable the ruler 15 to be adsorbed on the right side of the drawing board 1.

[0041] In this example, the telescopic component 5 includes a sliding rod 501 arranged on the upper and lower sides of the drawing board 1, and a first connecting sleeve 502 is fixedly connected to the surface of the sliding rod 501, and a damping rod 503 is slidably connected to the front end of the first connecting sleeve 502, and a second connecting sleeve 504 is slidably connected to the front end of the damping rod 503, and the second connecting sleeve 504 and the middle plate 6 are rotatably connected. The damping rod 503 on the device can ensure that the distance between the first connecting sleeve 502 and the second connecting sleeve 504 can remain stable after adjustment and will not be easily offset, thereby improving the stability of the device during operation.

[0042] In this example, the isometric ellipsograph 7 includes a first leg 701 slidably mounted above the middle plate 6, a second leg 702 slidably mounted below the middle plate 6, and a third leg 703 slidably mounted on the right side of the middle plate 6. Communication grooves 704 are formed on the surfaces of the first leg 701, the second leg 702, and the third leg 703. A convex block 705 is fitted inside the communication groove 704. The communication groove 704 and the convex block 705 enable the first leg 701, the second leg 702, and the third leg 703 to move straight, improving the stability of the device. The convex block 705 is fixedly connected to the middle plate 6. A folding plate 707 is hinged to the right side of the third leg 703. A cord 706 is wound around the outside of the middle plate 6, the first leg 701, the second leg 702, and the folding plate 707. The cord 706 is wound around the periphery of the device through the first leg 701, the second leg 702, and the folding plate 707 on the device. At this time, the triangle formed by the cord 706 is an isosceles triangle with an obtuse angle of 120°. At this moment, by folding the folding plate 707, the pen is moved along the inner side of the cord 706 at both ends of the first leg 701 and the third leg 703 to achieve the function of drawing an ellipse (combined with Figure 4 as can be seen).

[0043] In this example, a length scale line 10 is provided at the middle position on the right side of the middle plate 6. The position of the length scale line 10 corresponds to the position of the communication groove 704 on the third leg 703. Subsequently, when adjusting the position of the third leg 703, the ellipse with different minor axis lengths is drawn with the length scale line 10 as the reference line, thereby realizing the function of adjusting the size of the ellipse.

[0044] In this example, the synchronous adjustment component 9 includes a first synchronous pulley 901 tightly mounted on the left side of the first leg 701, a fourth synchronous pulley 904 tightly arranged on the right side of the first leg 701, a sixth synchronous pulley 906 tightly arranged above the third leg 703, and a fifth synchronous pulley 905 tightly arranged above the sixth synchronous pulley 906. During the movement of the third leg 703, the sixth synchronous pulley 906 is driven to rotate, and the sixth synchronous pulley 906 drives the fifth synchronous pulley 905 to rotate. A third synchronous pulley 903 is tightly arranged on the left side of the second leg 702, and a second synchronous pulley 902 is tightly arranged above the third synchronous pulley 903. The first synchronous pulley 901 is connected to the second synchronous pulley 902 through a synchronous belt, and the fourth synchronous pulley 904 is connected to the fifth synchronous pulley 905 through a synchronous belt. As shown in Figure 5 through the fifth synchronous pulley 905 and the synchronous belt on the device, the fourth synchronous pulley 904 is driven to rotate, so that the first leg 701 moves synchronously. During the movement of the first leg 701, the first synchronous pulley 901, the second synchronous pulley 902, and the third synchronous pulley 903 are driven to rotate, so that the legs at various parts of the device move synchronously, thereby realizing the function of drawing ellipses with different eccentricities.

[0045] In this example, the first synchronous wheel 901, the second synchronous wheel 902, the third synchronous wheel 903, the fourth synchronous wheel 904, the fifth synchronous wheel 905 and the sixth synchronous wheel 906 are all made of rubber, and the connection between the first synchronous wheel 901, the second synchronous wheel 902, the third synchronous wheel 903, the fourth synchronous wheel 904, the fifth synchronous wheel 905 and the sixth synchronous wheel 906 and the middle plate 6 is a rotation connection. The diameters of the first synchronous wheel 901, the second synchronous wheel 902, the third synchronous wheel 903 and the fourth synchronous wheel 904 are the same, the diameters of the fifth synchronous wheel 905 and the sixth synchronous wheel 906 are the same, and the diameter of the fourth synchronous wheel 904 is 1.732 times the diameter of the fifth synchronous wheel 905, ensuring that the ratio of the major axis to the minor axis of the drawn ellipse is 1.732:1, so that the drawn ellipse can be combined Figure 4 As shown, the device can now draw an isometric ellipse, and by changing the lengths of the major axis and the minor axis in a certain proportion, the device can draw isometric ellipses of different sizes.

[0046] In this example, the clamping assembly 11 includes a fixed shaft 1101 fixedly mounted on the surface of the middle plate 6, a rubber sleeve 1102 is rotatably connected to the outer side of the fixed shaft 1101, a first damping block 1103 is fixedly connected to the inner wall of the rubber sleeve 1102, and a second damping block 1104 is fixedly connected to the outer wall of the fixed shaft 1101. The first damping block 1103 is used to resist the second damping block 1104, so that the device can be engaged every time the rubber sleeve 1102 rotates a certain angle, so that the device can remain fixed when the size of the drawn ellipse is adjusted, thereby improving the stability of the device when drawing.

[0047] In this example, the angle adjuster 12 includes a fixing sleeve 1201 fixedly mounted on the upper and lower sides of the left end of the drawing board 1, a connecting rod 1202 is slidably mounted inside the fixing sleeve 1201, a rotating rod 1203 is rotatably connected to the left side of the upper connecting rod 1202, and a rotating sleeve 1204 is rotatably connected to the left side of the lower connecting rod 1202, and a clamping bolt 1205 is connected to the internal thread at the top of the rotating sleeve 1204. By changing the position of the rotating rod 1203 inside the rotating sleeve 1204, the angle of the rotating sleeve 1204 can be adjusted, and the clamping bolt 1205 is used to adjust the angle of the rotating sleeve 1204. 1205 allows the rotating rod 1203 to be fixed after the position inside the rotating sleeve 1204 is adjusted, thereby adjusting and fixing the positions of the connecting rods 1202 on the upper and lower sides. The rotating rod 1203 is slidably installed inside the rotating sleeve 1204, and the position of the right end of the connecting rod 1202 corresponds to the position of the sliding rod 501, so that the device can support the sliding rod 501 through the connecting rod 1202 after adjusting the angles of the sliding rods 501 on the upper and lower sides, so that the sliding rod 501 can move horizontally left and right at a specific angle, thereby improving the overall stability.

[0048] In this example, the longitudinal section of the scale plate 15 is in the shape of a regular hexagon. There are three wire grooves 16 equally angularly distributed on the surface of the scale plate 15. The ends of the wire groove 16 and the adjacent wire groove 16 are interconnected. Each side of the regular isometric cuboid is drawn through the wire groove 16 on the scale plate 15. The wire groove 16 can not only serve as a limiting groove for the movement of the paintbrush but also serve as a reference line for drawing the edges of the regular isometric cube.

[0049] It should be noted that the present invention is an indoor design drawing board with an axonometric auxiliary function and its usage method. First, in combination with Figures 1-3 As shown, the drawing paper is fixed through the adhesive layer 2 on the drawing board 1. When drawing an axonometric drawing, by pulling the scale plate 15, the second magnetic block 14 on the left side of the scale plate 15 is separated from the first magnetic block 13. Three wire grooves 16 equally angularly distributed on the surface of the scale plate 15 are used to draw a regular isometric rectangle or cuboid, and one of the wire grooves 16 is used as a reference line to draw the other edges of the regular isometric rectangle or cuboid; in combination with Figure 1 、 Figure 3 and Figure 4 As shown, through the damping rod 503 on the telescopic component 5, the first connecting sleeve 502 and the second connecting sleeve 504 on the upper and lower sides of the damping rod 503 are fixed after position adjustment, so that the included angle of the connecting lines of the upper and lower slide rods 501 changes, and then the angle of the middle plate 6 is adjusted. Since the middle plate 6 and the second connecting sleeve 504 are rotatably connected, when drawing a sketch with a low precision requirement, the angles of the middle plate 6 in the middle position of the drawing board 1 and the regular isometric ellipse gauge 7 can also be directly adjusted. The lighting function of the lamp board 3 is used to make the drawing paper translucent, and the angle scale line 4 adjusts the angle of the regular isometric ellipse gauge 7, so as to accurately adjust the angle of the isometric ellipse;

[0050] As Figure 1 and Figures 3-9 shown, after adjusting the elongation of the upper and lower telescopic components 5, the angle of the left half of the angle adjuster 12 can be adjusted through the angle adjuster 12. By changing the position of the rotating rod 1203 in the rotating sleeve 1204, and then adjusting and fixing the position of the rotating rod 1203 through the compression bolt 1205. At this time, the angle of the rotating rod 1203 changes, and the right end of the connecting rod 1202 in the fixed sleeve 1201 on the upper and lower sides can abut against the slide rod 501 on the inclined telescopic component 5. During the process of translating the angle adjuster 12 to the right, the inclined middle plate 6 and the regular isometric ellipse gauge 7 can be horizontally moved, so as to draw regular isometric ellipses at different angles at a specific position on the drawing paper; in combination with Figure 3 and Figure 4 shown, after the regular isometric ellipse gauge 7 rotates 90° clockwise, 30° counterclockwise, and 30° clockwise, the device can draw the regular isometric ellipses of the top surface, left side surface, and right side surface of the cube; during the drawing process, in combination withFigure 4 , Figure 8 and Figure 9 As shown in Figure 9 , the tether 706 is wound around the outer sides of the first leg 701, the second leg 702, the folding plate 707, and the handle 8. Combining Figure 4 , the angle between the upper right side of the tether 706 and the first leg 701 is 30°. At this time, the size of the drawn ellipse is adjusted through the synchronous adjustment assembly 9 on the outside of the isometric ellipse gauge 7. Therefore, during the process of the folding plate 707 moving to the right, the moving length is determined by the length scale line 10. The third leg 703 drives the sixth synchronous wheel 906 to rotate, and the sixth synchronous wheel 906 drives the fifth synchronous wheel 905 and the fourth synchronous wheel 904 to rotate. The fourth synchronous wheel 904 drives the first leg 701 to move, and it moves under the action of the first synchronous wheel 901, the second synchronous wheel 902, and the third synchronous wheel 903. The communication groove 704 and the convex block 705 enable the first leg 701, the second leg 702, and the third leg 703 to remain straight when moving synchronously. Since the diameter of the fourth synchronous wheel 904 is 1.732 times the diameter of the fifth synchronous wheel 905, when the third leg 703 moves, the moving distances of the second leg 702 and the third leg 703 are 1.732 times the moving distance of the third leg 703, making the obtuse angle of the equilateral triangle formed by the front-end connection lines of the first leg 701, the second leg 702, and the folding plate 707 on the device be 120°. At this time, the tether 706 is wound around the outer sides of the handle 8, the first leg 701, the second leg 702, and the folding plate 707 (as shown in Figure 4 , Figure 8 , and Figure 9 ). The folding plate 707 is retracted, and the paintbrush tightens the tether 706 to draw one half of the ellipse. Then, the tether 706 is moved to the left to draw the other side of the ellipse, thereby realizing the function of drawing isometric ellipses of different sizes. The mutually staggered first damping blocks 1103 and second damping blocks 1104 on the fixed shaft 1101 and the rubber sleeve 1102 can complete a clamping and fixing every time the third leg 703 moves a certain length, making it difficult for the third leg 703 to shift after adjustment;

[0051] As Figure 1 and Figure 3 shown, during the drawing process, the clamping assembly 11 enables the isometric ellipse gauge 7 to move horizontally left and right after the adjustment is completed. By sliding the rotating rod 1203 inside the rotating sleeve 1204, during the adjustment process, the connecting rods 1202 on the upper and lower sides expand and contract to different degrees inside the fixed sleeve 1201. When the connecting rods 1202 on the upper and lower sides abut against the slide rods 501 at different positions, the rotating rod 1203 is pressed and fixed by the pressing bolt 1205, enabling the isometric ellipse gauge 7 to move horizontally left and right after the angle adjustment is completed.
