DETAILED DESCRIPTION

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. The meaning of "several" is one or more, unless otherwise clearly and specifically defined.

[0031] In engineering design, in order to ensure the consistency between the design and the site, accurate survey and drawing of site drawings are required. Therefore, designers need to carry survey and drawing tools such as drawing boards, compasses, pens, erasers and rulers. The existing drawing board products are small in size, and multiple sheets of paper need to be replaced and drawings need to be saved with separate numbers. When facing continuous long-distance and long-term outdoor surveys, they are easily affected by the length of the paper and cannot guarantee the consistency and accuracy of the survey and drawing.

[0032] In the prior art, a storage cylinder is usually connected to the rear end of the drawing board, and the completed drawing paper rolls are stored in the storage cylinder, which needs to be collected and numbered separately. In addition, the drawing board is equipped with mechanical devices such as chains, gears, rollers, motors and cutting rods, and the motor is used as the power to transmit the paper, which increases the weight of the drawing board and makes the structure complicated.

[0033] In view of the above problems, an embodiment of the utility model provides a multifunctional drawing board, which can solve the problem that the drawing board in the prior art has a single function and is inconvenient to carry.

[0034] Figure 1The structure diagram of the multifunctional drawing board provided in the embodiment of the utility model is shown. Figure 1 As shown, the multifunctional drawing board comprises: a drawing board body 1, a first reel 3, a second reel 5 and a drawing assembly 6, wherein the first reel 3 is arranged at the first end 2 of the drawing board body 1, the second reel 5 is arranged at the second end 4 of the drawing board body 1, and the drawing assembly 6 is arranged on the drawing board body 1; the drawing is used to be embedded in the second reel 5, and the starting end of the drawing can pass through the second reel 5 and can pass into the first reel 3 after passing through the drawing board body 1, the first reel 3 is used to store the completed drawings, and the second reel 5 is used to store the unused drawings.

[0035] In actual application, in a multifunctional drawing board, the first reel 3 is arranged at the first end 2 of the drawing board body 1, the second reel 5 is arranged at the second end 4 of the drawing board body 1, and the drawing component 6 is arranged on the drawing board body 1. Based on this, the drawing is used to be embedded in the second reel 5, and the starting end of the drawing can pass through the second reel 5 and can pass into the first reel 3 after passing through the drawing board body 1. The first reel 3 is used to store the completed drawings, and the second reel 5 is used to store the unused drawings. It can be understood that the above-mentioned drawings should be a complete rectangular roll of paper. When the draftsman needs to change the drawing paper, the completed drawings can be collected in the first reel 3 by rotating the first reel 3. When the first reel 3 is rotated, the drawings located in the second reel 5 will be driven to pass the unused part of the drawings out of the second reel 5 again until they are laid on the drawing board body. The drawing user can then draw again. Therefore, the first reel 3 can be rotated to store the completed drawings, and the first reel 3 is used to store the completed drawings. In addition, when the roll of paper in the second reel 5 is used up, the second reel 5 can be opened and new roll of paper can be loaded into the second reel 5, so that the roll of paper can be replaced.

[0036] On this basis, the user only needs to rotate the first reel 3 to realize the above-mentioned drawing storage process, without the need to use a motor or other mechanical transmission method to realize the transmission of the drawings, thereby reducing the weight of the drawing board and making it convenient for the user to carry. At the same time, the reverse rotation of the second reel 5 can pass the drawings collected in the first reel 3 out of the first reel 3 and lay them on the drawing board body 1, which is conducive to the draftsman to check the drawings that have been drawn and convenient for the draftsman to check the drawings. In the above-mentioned drawing board, the drawings can be replaced and stored, and can also be checked and checked, realizing the multi-functional application of the drawing board, and effectively solving the problem that the drawing board in the prior art has a single function and is inconvenient to carry.

[0037] For example, Figure 2 The schematic diagram of the structure of the first reel 3 provided in the embodiment of the utility model is shown as follows: Figure 2As shown, the first reel 3 includes: a first component 31, a second component 32, a connecting piece 35, a first end cover 33 and a second end cover 34. The first component 31 and the second component 32 form a cylinder body of the first reel 3 through the connecting piece. The first end cover 33 is buckled at one end of the cylinder body, and the second end cover 34 is buckled at the other end of the cylinder body.

[0038] In practical applications, such as Figure 2 As shown, the first component 31 and the second component 32 form the cylinder body of the first reel 3 through a connecting member. It can be understood that the connecting member 35 can be a hinge connecting member, a rotating connecting member, etc. The first component 31 and the second component 32 are arranged as a detachable connecting member to facilitate replacement and loading of the roll paper into the cylinder body. The first end cover 33 is snapped on one end of the cylinder body, and the second end cover 34 is snapped on the other end of the cylinder body. The first end cover 33 and the second end cover 34 are respectively arranged at both ends of the cylinder body, which can not only reinforce the cylinder body, but also make the first end cover 33 and the second end cover 34 of the paper roll cooperate with each other to realize the rotation of the roll in the cylinder body.

[0039] For example, Figure 2 As shown, the second component 32 has a limiting hole 321 for the drawing to pass through. The limiting hole 321 can not only facilitate the drawing to pass through the cylinder, but also limit the position of the drawing, effectively avoiding the problem of the drawing being shaken by wind when the user uses it outdoors, and facilitating the user's use outdoors.

[0040] Figure 3 The structure diagram of the first end cover 33 provided in the embodiment of the utility model is shown. Figure 4 The structure diagram of the paper roll shaft provided in the embodiment of the utility model is shown as follows: Figure 3-4 As shown, the first end cover 33 includes a first sub-end cover 331 and a second sub-end cover 332, and the first sub-end cover 331 is fixedly connected to the second sub-end cover 332. It can be understood that the end of the above-mentioned paper roll shaft 42 connected to the first end cover 33 is a groove structure, the groove 41 of the paper roll shaft is adapted to the first end cover 33, and the end of the paper roll shaft 42 connected to the second end cover 34 is a boss structure. At the same time, the first sub-end cover 331 is buckled on the cylinder body, and the second sub-end cover 332 is embedded in the inner wall of the cylinder body. It should be understood that the second sub-end cover 332 is rotatably connected to the first sub-end cover 331.

[0041] Exemplarily, the second sub-end cover 332 is a boss structure, and the boss structure of the second sub-end cover 332 is adapted to the groove 41 structure of the paper roll shaft. It should be understood that the boss structure should be a polygonal boss, and the polygonal boss is adapted to the groove. At the same time, the position of the paper roll shaft can also be limited, so that the second sub-end cover 332 can rotate synchronously with the paper roll shaft. On this basis, the outer diameter of the second sub-end cover 332 is smaller than the outer diameter of the first sub-end cover 331. Since the second sub-end cover 332 is embedded in the inner side wall of the cylinder, it is necessary to rotate the second sub-end cover 332 to drive the rotation of the paper roll shaft. Therefore, the outer diameter of the second sub-end cover 332 is smaller than the outer diameter of the first sub-end cover 331.

[0042] Exemplarily, the end face of the second sub-end cover close to the inner side of the cylinder body is a concave-convex surface. It can be understood that the end face of the second sub-end cover close to the inner side of the cylinder body is uneven, and the end face of the second sub-end cover close to the inner side of the cylinder body is defined as a concave-convex surface. The concave-convex surface 334 of the second sub-end cover is specifically a five-leaf pattern design. When the paper roll shaft rotates, the concave-convex surface 334 of the second sub-end cover fits perfectly with the groove 41 of the paper roll shaft, driving the paper roll shaft to rotate synchronously.

[0043] in addition, Figure 5 FIG. 3 shows a schematic diagram of the structure of the rotating member 333 provided in the embodiment of the utility model. Figure 5 As shown, a rotating member 333 is further provided on the end surface of the first end cover 33 facing away from the cylinder body, and the rotating member 333 is rotatably connected to the geometric center of the second sub-end cover 332. It should be understood that the rotating member 333 can be snapped on the end surface of the first sub-end cover 331 facing away from the cylinder body. When in use, the rotating member 333 can be snapped out of the first sub-end cover 331, and the rotation of the paper roll shaft can be achieved by rotating the rotating member 333. When not in use, the rotating member 333 is snapped on the end surface of the first sub-end cover 331 facing away from the cylinder body.

[0044] Exemplarily, the second end cover 34 is a groove structure, and the groove structure is also sleeved with an elastic member for mounting the paper roll shaft, and the elastic member is embedded in the groove structure along the axial direction of the cylinder.

[0045] In practical applications, the groove structure of the second end cover 34 is adapted to the boss structure of the paper roll shaft to fix the paper roll shaft. At the same time, the groove structure is also sleeved with an elastic member for installing the paper roll shaft, and the elastic member is embedded in the groove structure along the axial direction of the cylinder. It can be understood that the elastic member can be a spring, an elastic plate, etc., and the elastic member can be compressed by using the principle that the elastic member can be compressed. When the paper roll shaft is placed in the cylinder, the boss of the paper roll shaft is used to squeeze the elastic member until the groove of the paper roll shaft is connected to the boss of the first end cover 33. The first end cover 33 and the second end cover 34 are set to the above structure, so that the paper roll shaft can be quickly installed, and it is also convenient for users to replace the paper roll shaft.

[0046] Exemplarily, the structure of the first reel 3 is the same as that of the second reel 5 , which will not be described in detail here, and the beneficial effects of the second reel 5 are the same as those of the first reel 3 , which will not be described here.

[0047] In an optional manner, the geometric center of the first end cover 33, the geometric center of the second end cover 34 and the geometric center of the paper roll shaft are located on the same central axis. When the rotating member 333 is rotated, it can be ensured that the first end cover 33, the second end cover 34 and the paper roll shaft rotate coaxially, so that the above-mentioned shaft is transmitted smoothly during the rotation process.

[0048] For example, Figure 1 As shown, the drawing component 6 includes: a drawing ruler 61, a compass 64, a pen and an eraser. The drawing ruler 61 and the compass 64 are slidably connected to the drawing board body 1 through a universal rotating hose; the drawing board body 1 also has a pen slot 62 for placing the pen and an eraser slot 63 for placing the eraser. The pen is located in the pen slot 62, and the eraser is located in the eraser slot 63.

[0049] In practical applications, such as Figure 1 As shown, a slide rail is provided inside the drawing board body 1, and the drawing ruler 61 and the compass 64 are both slidably connected to the drawing board body 1 through a universal rotating hose. The universal rotating hose allows the user to freely slide the drawing ruler 61 on the drawing paper when in use, which is conducive to drawing drawings quickly, accurately and beautifully with the help of the drawing ruler 61. When not in use, the drawing ruler 61 and the compass 64 can be hidden in the drawing board. At the same time, the drawing board body 1 also has a pen slot 62 for placing a pen and an eraser slot 63 for placing an eraser. The pen is located in the pen slot 62, and the eraser is located in the eraser slot 63. The user can quickly find the required pen when drawing, and can quickly find the eraser when the drawing needs to be changed, which is convenient for the user to use.

[0050] For example, Figure 1 As shown, the drawing board body 1 is also provided with a first limiting groove 7 and a second limiting groove 8 for limiting the position of the paper, and the first limiting groove 7 and the second limiting groove 8 are both marked with size scales; the first limiting groove 7 and the limiting groove near the first reel 3 are also provided with a paper pasting opening.

[0051] In practical applications, such as Figure 1 As shown, the drawing board body 1 is also provided with a first limiting groove 7 and a second limiting groove 8 for limiting the position of the paper. The first limiting groove 7 and the second limiting groove 8 are both marked with size scales. When using the drawing for drawing, the edge of the drawing is inserted into the first limiting groove 7 and the second limiting groove 8. In windy weather and other weather conditions, the straightness and stability of the drawing paper on the drawing board can be effectively guaranteed.

[0052] In addition, the first limiting groove 7 and the position of the limiting groove near the first reel 3 are also provided with a paper pasting opening. When the draftsman uses multiple drawings, the end of each drawn drawing can be pulled to the pasting opening, and the end of the drawn drawing and the starting part of the undrawn drawing can be pasted together at the pasting opening, so that the entire drawn drawing is combined into a whole roll of paper. The drawn drawings are collected by rotating the first reel, and at the same time, the drawn drawings can be checked by rotating the second reel in the opposite direction. There is no need to number the multiple drawings again, which facilitates the draftsman's organization and collection.

[0053] For example, Figure 1 As shown, the multifunctional drawing board also includes a shoulder strap 9, the ends of which are connected to the drawing board body 1. When drawing, it can be hung in front of the chest to facilitate drawing operations. When not in use, it can be carried outdoors for quick movement.

[0054] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
