A combination drawing board

Abstract

This utility model discloses a modular drawing board, comprising at least two drawing board units, each drawing board unit having a drawing board body. This utility model allows multiple drawing board bodies to be assembled by inserting a snap-fit ​​strip into a snap-fit ​​frame fixed to the side of another set of drawing board bodies via a set of drawing board bodies. Simultaneously, pulling a pull rod causes a connecting rod to slide along a limiting rod within the fixed frame, facilitating the insertion of the limiting rod into the snap-fit ​​frame and limiting the position of the assembled drawing board bodies. Third magnetic blocks installed at both ends of the limiting rod allow it to attract the first and second magnetic blocks respectively during insertion or storage, aiding in the limiting rod's function and preventing it from wobbling along the fixed frame during movement of the multiple drawing board bodies. Furthermore, mounting bolts pass through a mounting plate and are threaded to the surface of the drawing board body, allowing for easy assembly and disassembly of the snap-fit ​​frame and the fixed frame as a whole.

Description

Technical Field

[0001] This utility model relates to the field of drawing board technology, and in particular to a modular drawing board. Background Technology

[0002] In the Chinese vocabulary system, a drawing board refers to a flat tool used to fix drawing paper during painting. Its core function is to support the painting medium. Traditional drawing boards are mostly made of wood, which has flat and stable physical properties, and together with brushes, paints, etc., they form a complete system of painting tools.

[0003] Existing drawing boards have a fixed overall size, which means that they can only hold drawing paper of the same size, making it inconvenient to place drawing paper of different lengths. To address this problem, we propose a modular drawing board. Utility Model Content

[0004] The purpose of this invention is to solve the problem of fixed overall size of drawing boards in the prior art, which means that drawing boards of fixed size can only hold drawing paper of the same size, making it inconvenient to place drawing paper of different lengths. Therefore, a modular drawing board is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A modular drawing board includes at least two drawing board units, each drawing board unit having a drawing board body. The back of the drawing board body is provided with a mounting mechanism, and both ends of the mounting mechanism are respectively provided with a plug-in mechanism and a limiting mechanism. The plug-in mechanism includes a plug-in frame fixed to one end of the mounting mechanism. The limiting mechanism includes a fixing frame fixed to the other end of the mounting mechanism. The fixing frame has a limiting groove, in which a limiting rod is inserted. The limiting rod is movable relative to the fixing frame and has a limiting position for extending part of the limiting rod out of the fixing frame to insert into the plug-in frame on an adjacent drawing board body, and a release position for retracting the limiting rod to release the limiting position. At least one side of the drawing board body is provided with a splicing mechanism, which is used to engage with the splicing mechanism of another drawing board body to achieve lateral splicing of adjacent drawing board units.

[0007] Preferably, the mounting mechanism includes a mounting plate, which is fixed to the back of the drawing board body by mounting bolts, and the insertion frame of the insertion mechanism and the fixing frame of the limiting mechanism are respectively fixedly disposed at both ends of the mounting plate.

[0008] Preferably, the upper and lower ends of the drawing board body are provided with mounting plates, and each mounting plate is provided with two mounting bolts.

[0009] Preferably, the insertion frame has an insertion groove inside, a first magnetic block is fixedly installed on the inner wall of the insertion groove, a second magnetic block is fixedly installed on the inner wall of the limiting groove of the fixing frame, and a third magnetic block is fixedly installed at both ends of the limiting rod. When the limiting rod is in the limiting position, the third magnetic block at one end of the limiting rod magnetically engages with the first magnetic block; when the limiting rod is in the releasing position, the third magnetic block at the other end of the limiting rod magnetically engages with the second magnetic block.

[0010] Preferably, a connecting rod is fixedly connected to the surface of the limiting rod, and a pulling rod is fixedly connected to the outer end of the connecting rod. The surface of the fixing frame is provided with a strip-shaped through groove adapted to the connecting rod, and the diameter of the pulling rod is greater than the width of the strip-shaped through groove.

[0011] Preferably, the splicing mechanism includes a snap-fit ​​frame and a snap-fit ​​strip. A snap-fit ​​frame is fixedly connected to one side of the drawing board body, and a snap-fit ​​strip adapted to the snap-fit ​​frame is fixedly connected to the opposite side. The snap-fit ​​frame and the snap-fit ​​strip of the adjacent drawing board unit snap-fit ​​together.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This device uses a set of drawing board bodies to drive the snap-fit ​​strip to insert into the snap-fit ​​frame fixed on the side of another set of drawing board bodies, which can splice and assemble multiple drawing board bodies. At the same time, by pulling the pull rod, the connecting rod can drive the limiting plug rod to slide along the fixed frame, which makes it easy to insert the limiting plug rod into the plug frame, thus limiting the spliced ​​multiple drawing board bodies.

[0014] 2. The device has a third magnetic block installed at both ends of the limiting rod. When the limiting rod is inserted or stored, it can attract the first and second magnetic blocks respectively, which facilitates the function of the limiting rod and prevents the limiting rod from swaying along the fixed frame during the movement of multiple drawing boards. At the same time, the mounting bolts pass through the mounting plate and are threaded to the surface of the drawing board, which makes it easy to disassemble and assemble the insertion frame and the fixed frame as a whole.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-4 A modular drawing board includes at least two drawing board units. Each drawing board unit has a drawing board body 1. The back of the drawing board body 1 is provided with a mounting mechanism 3. The two ends of the mounting mechanism 3 are respectively provided with a plug-in mechanism 2 and a limiting mechanism 4. The plug-in mechanism 2 includes a plug-in frame 21, which is fixed to one end of the mounting mechanism 3. The limiting mechanism 4 includes a fixing frame 41, which is fixed to the other end of the mounting mechanism 3. The fixing frame 41 is provided with a limiting groove, in which a limiting rod 43 is inserted. The limiting rod 43 can move relative to the fixing frame 41 and has a limiting position for extending part of the limiting rod 43 out of the fixing frame 41 to insert into the plug-in frame 21 on the adjacent drawing board body 1, and a release position for retracting the limiting rod 43 to release the limiting position. At least one side of the drawing board body 1 is provided with a splicing mechanism 5, which is used to engage with the splicing mechanism 5 of another drawing board body to achieve lateral splicing of adjacent drawing board units.

[0026] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the mounting mechanism 3 includes a mounting plate 32, which is fixed to the back of the drawing board body 1 by mounting bolts 31. The insertion frame 21 of the insertion mechanism 2 and the fixing frame 41 of the limiting mechanism 4 are respectively fixed at both ends of the mounting plate 32. The upper and lower ends of the drawing board body 1 are provided with mounting plates 32. Each mounting plate 32 is provided with two mounting bolts 31. The mounting bolts 31 pass through the mounting plate 32 and are threadedly connected to the drawing board body 1, which can facilitate disassembly and assembly. At the same time, the mounting plate 32 is installed with two mounting bolts 31, which can increase the installation stability of the mounting plate 32.

[0027] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the plug-in frame 21 has a plug-in groove inside, and a first magnetic block 22 is fixedly installed on the inner wall of the plug-in groove. A second magnetic block 42 is fixedly installed on the inner wall of the limiting groove of the fixing frame 41. A third magnetic block 44 is fixedly installed at both ends of the limiting plug rod 43. When the limiting plug rod 43 is in the limiting position, the third magnetic block 44 at one end of it magnetically engages with the first magnetic block 22. When the limiting plug rod 43 is in the releasing position, the third magnetic block 44 at the other end of it magnetically engages with the second magnetic block 42. The groove opened in the plug-in frame 21 facilitates the insertion of the limiting plug rod 43. The first magnetic block 22 can attract the third magnetic block 44, which facilitates the limiting plug rod 43 to be limited in the plug-in frame 21. The groove opened in the fixing frame 41 can be used to store the limiting plug rod 43. The second magnetic block 42 can attract the third magnetic block 44, which facilitates the storage of the limiting plug rod 43 when not in use.

[0028] Furthermore, refer to Figure 3 and Figure 4 It can be seen that a connecting rod 45 is fixedly connected to the surface of the limiting rod 43, and a pulling rod 46 is fixedly connected to the outer end of the connecting rod 45. A strip-shaped through groove adapted to the connecting rod 45 is opened on the surface of the fixing frame 41. The diameter of the pulling rod 46 is larger than the width of the strip-shaped through groove. By pulling the pulling rod 46, the connecting rod 45 can drive the limiting rod 43 to move. A third magnetic block 44 is inserted into both ends of the limiting rod 43. The third magnetic block 44 inserted into both ends of the limiting rod 43 can be easily attracted to the first magnetic block 22 and the second magnetic block 42 respectively. The connecting rod 45 can slide along the strip-shaped through groove opened on the surface of the fixing frame 41, which plays the role of limiting and driving the limiting rod 43. The surface diameter of the pulling rod 46 is larger than the width of the strip-shaped through groove. The pulling rod 46 can easily limit and pull the connecting rod 45.

[0029] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the splicing mechanism 5 includes a snap-fit ​​frame 51. The snap-fit ​​frame 51 is fixedly connected to one side of the drawing board body 1, and the snap-fit ​​strip 52 is fixedly connected to the other side of the drawing board body 1. The snap-fit ​​strip 52 is inserted into the snap-fit ​​frame 51. Since the cross-section of the snap-fit ​​strip 52 is set to T-shape, and the snap-fit ​​frame 51 has a groove that matches it, it is convenient to assemble and use the two drawing board bodies 1.

[0030] Working principle: When the drawing board body 1 is in use, according to the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4By passing the mounting bolt 31 through the mounting plate 32, the plug-in frame 21 and the fixing frame 41 can be installed on the surface of the drawing board body 1. At this time, the snap-fit ​​strip 52 is inserted into the snap-fit ​​frame 51 fixed on the side of another set of drawing board bodies 1 by one set of drawing board bodies 1, so that the two drawing board bodies 1 can be spliced ​​together. At the same time, by pulling the pulling rod 46, the connecting rod 45 can drive the limiting plug 43 to slide along the fixing frame 41. When the limiting plug 43 is inserted into the plug-in frame 21, the third magnetic block 44 and the first magnetic block 22 can be attracted to each other, and the limiting plug 43 is limited in the plug-in frame 21, so that the combination splicing of the two drawing board bodies 1 can be completed.

[0031] The above is the complete working principle of this utility model.
