Description

Technical Field

[0001] This utility model relates to the technical field of electronic drawing board auxiliary devices, specifically an auxiliary device for an electronic art drawing board. Background Technology

[0002] In the field of art creation, digital drawing tablets have become an important creative tool; however, their auxiliary devices still have many shortcomings. Existing auxiliary devices have significant deficiencies in supporting and protecting digital drawing tablets. Most devices only provide support at a single angle and cannot be flexibly adjusted according to the creator's needs, leading to fatigue for the creator while drawing.

[0003] While some existing technologies have adjustable support angle auxiliary devices, they do not have the function of fixing the position after adjustment. This makes it easy for the angle to change during drawing, or even flatten out directly, resulting in poor stability of the angle. A great deal of research has been conducted on this issue. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an auxiliary device for an electronic drawing board, which can protect the screen of the electronic drawing board when it is stored, and can be adjusted and fixed at multiple angles when unfolded, so as to facilitate comfortable use by the creator.

[0005] This utility model is achieved through the following technical solution: An auxiliary device for an electronic drawing board of art, comprising a placement plate, on one side of which an electronic drawing board is placed. The device is characterized in that a cover plate is rotatably mounted on the placement plate, and a telescopic plate is slidably mounted on one side of the cover plate. A locking assembly is provided between the cover plate and the telescopic plate. Multiple grooves are provided on the back side of the placement plate. When the cover plate and the telescopic plate are flipped to the back side of the placement plate, the telescopic plate extends out of the cover plate and engages with the grooves. The telescopic plate and the cover plate are slidably connected via a sliding groove assembly.

[0006] In a further technical solution, a protruding plate is provided at the bottom of the placement plate, and side plates are provided on the front and rear sides of the placement plate.

[0007] In a further technical solution, the placement plate is provided with multiple heat dissipation holes.

[0008] In a further technical solution, the cross-section of the groove is square or triangular.

[0009] A further technical solution includes a locking assembly comprising a guide rail fixedly disposed on one side of the telescopic plate, an inner groove provided in the guide rail, a sliding groove provided in the cover plate, a pressure block slidably disposed in the sliding groove, a threaded shaft fixedly disposed on one side of the pressure block, and an internal threaded shaft rotatably disposed in the cover plate, the internal threaded shaft being threadedly connected to the threaded shaft.

[0010] In a further technical solution, a rotating wheel is fixedly installed on one side of the internally threaded shaft.

[0011] A further technical solution is provided in which a first limiting plate is fixedly provided on the outer surface of the internal threaded shaft, a rotating seat is fixedly provided on one side of the cover plate, the internal threaded shaft is movably disposed in the rotating seat, the internal threaded shaft passes through the rotating seat, and a second limiting plate is fixedly provided on the outer surface of the rotating seat, thereby limiting the rotating seat to both sides by the first limiting plate and the second limiting plate respectively.

[0012] In a further technical solution, the slide rail assembly includes a movable groove disposed within the cover plate, and the telescopic plate is slidably disposed within the movable groove.

[0013] The beneficial effects of this utility model are as follows: First, by connecting the telescopic plate and the cover plate through a sliding groove assembly and locking the positions of the telescopic plate and the cover plate through a locking assembly, the screen of the electronic drawing board is protected after the telescopic plate and the cover plate are closed during the storage stage. During the unfolding stage, the telescopic plate is first stored in the cover plate, and then the cover plate and the telescopic plate are flipped so that the cover plate and the telescopic plate are flipped towards the back of the placement plate. Then, the rectangular protrusion at the end of the telescopic plate engages with the groove and is pressed tightly. The locking assembly is used to fix the relative positions of the telescopic plate and the cover plate. With the rectangular protrusion engaging with the groove, the positions of the cover plate and the placement plate remain unchanged, making the electronic drawing board more stable when the user uses it at an angle.

[0014] Second, regarding the locking assembly, by setting a first limiting plate and a second limiting plate, the internal threaded shaft can move within the rotating seat, preventing the threaded shaft and the rotating wheel from moving axially, thereby indirectly improving the convenience of personnel operation.

Detailed Implementation

[0027] like Figures 1-10 As shown, this utility model will be described in detail. For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1The projection relationship is consistent in the up, down, left, right, front, and back directions. The auxiliary device of the electronic drawing board of this utility model includes a placement plate 11, an electronic drawing board 23 placed on one side of the placement plate 11, a cover plate 12 rotatably disposed on the placement plate 11, a telescopic plate 13 slidably disposed on one side of the cover plate 12, a locking component disposed between the cover plate 12 and the telescopic plate 13, and a plurality of grooves 15 disposed on the back side of the placement plate 11. When the cover plate 12 and the telescopic plate 13 are flipped to the back side of the placement plate 11, the telescopic plate 13 extends out of the cover plate 12 and engages with the grooves 15, so that the cover plate 12 and the placement plate 11 form a triangular support structure with an angle. The telescopic plate 13 and the cover plate 12 are slidably connected by a sliding groove component.

[0028] Advantageously, the bottom of the placement plate 11 is provided with a protruding plate 22, which is used to snap the bottom of the electronic drawing board 23, and the front and rear sides of the placement plate 11 are provided with side plates 21, which are used to snap the sides of the electronic drawing board 23.

[0029] Advantageously, the placement plate 11 is provided with multiple heat dissipation holes.

[0030] Advantageously, the cross-section of the groove 15 is square or triangular, according to the attached instruction manual. Figure 7 As can be seen, its bottom angle is ∠A. The degree of ∠A represents the angle between the telescopic plate 13 and the placement plate 11. The degree of ∠A can be set to 90°. At this time, the cross-section of the groove 15 is square, and the telescopic plate 13 and the placement plate 11 maintain 90°. The degree of ∠A can be set from 30° to 90°. Furthermore, the position of the groove 15 is different depending on the degree. The smaller the degree, the farther away it is from the square groove 15.

[0031] Advantageously, a rectangular protrusion 33 is fixedly provided at the end of the telescopic plate 13. The rectangular protrusion 33 is engaged in the groove 15. When engaged, the rectangular protrusion 33 is completely abutted against the inner wall of the groove 15. Since a locking component is provided between the telescopic plate 13 and the cover plate 12, the telescopic plate 13 will not slide against the cover plate 12. After the rectangular protrusion 33 is engaged with the groove 15, one end face of the telescopic plate 13 abuts against the back end face of the placement plate 11. When there is a tendency to rotate the cover plate 12 and the telescopic plate 13, the end wall of the groove 15 will prevent the telescopic plate 13 and the rectangular protrusion 33 from flipping, so as to achieve the function of keeping the telescopic plate 13, the cover plate 12 and the placement plate 11 in a fixed position.

[0032] Advantageously, regarding the machining of the groove 15, a rectangular groove 15 is first machined on the back area of ​​the placement plate 11 according to dimensions D1 and D2. The hinge point 41 is the center of the hinge axis between the cover plate 12 and the placement plate 11. The dimensions of the X and Y axes from the hinge point 41 to the back area of ​​the placement plate 11 are known, namely D1 and D2. The vertical distance from the lower end face of the telescopic plate 13 to the hinge point 41 is D3. When the telescopic plate 13 is inserted into the rectangular groove 15, it can be known that D3 = D2. Furthermore, since the telescopic plate 13 is slidably disposed in the cover plate 12 through the sliding groove assembly, the dimension D3 will not change, that is, it is equal to D2. Therefore, the dimension D3 is also known. From the attached... Figure 7 It can be seen that as long as the distance from the contact point 42 to the lower end wall of the rectangular groove 15 is calculated, the Y-axis position of the contact point 42 is determined. Since the shape of the groove 15 is triangular in other positions, and the length of the bottom of the triangle is the same as the thickness of the rectangular protrusion 33, and the degree of ∠A is also known, the shape of the groove 15 can be processed.

[0033] Advantageously, regarding the distance from contact point 42 to the lower end wall of the rectangular groove 15, the line connecting contact point 42 and the intersection of the perpendicular line 43 is perpendicular to the line connecting hinge point 41 and the intersection of the perpendicular line 43. The line connecting hinge point 41 and the origin of coordinates 44 is perpendicular to the back of the placement plate 11. The lines connecting contact point 42 and the origin of coordinates 44 and the line connecting hinge point 41 and the intersection of the perpendicular line 43 intersect to form two triangles with ∠A. Given D1, the size of D4 is known. Subtracting D4 from D2 gives the size from the intersection point to the lower end wall of the rectangular groove 15. Given D3 and ∠A, the size from the intersection point to contact point 42 is known. By subtracting the two, the distance from contact point 42 to the lower end wall of the rectangular groove 15 is obtained. Thus, the orientation of multiple contact points 42 of the groove 15, as well as the shape and size of the groove 15, can be obtained, enabling the processing of grooves 15 that meet specifications.

[0034] Advantageously, the locking assembly includes a guide rail 31 fixedly disposed on one side of the telescopic plate 13, an inner groove 57 disposed in the guide rail 31, a slide groove 59 disposed in the cover plate 12, a pressure block 58 slidably disposed in the slide groove 59, a threaded shaft 55 fixedly disposed on one side of the pressure block 58, and an internal threaded shaft 54 ​​rotatably disposed in the cover plate 12. The internal threaded shaft 54 ​​and the threaded shaft 55 are threadedly connected. The threaded shaft 55 is disposed in the internal threaded shaft 54. After rotating the internal threaded shaft 54, the threaded shaft 55 and the pressure block 58 slide out of the slide groove 59 and are pressed and rubbed against the inner groove 57 to fix them, so that the guide rail 31 and the telescopic plate 13 remain relatively fixed to the cover plate 12.

[0035] Advantageously, a rotating wheel 52 is fixedly provided on one side of the internal thread shaft 54.

[0036] Advantageously, a first limiting plate 53 is fixedly provided on the outer surface of the internal thread shaft 54, and a rotating seat 51 is fixedly provided on one side of the cover plate 12. The internal thread shaft 54 ​​is movably disposed in the rotating seat 51 and passes through the rotating seat 51. A second limiting plate 56 is fixedly provided on the outer surface of the rotating seat 51. The first limiting plate 53 and the second limiting plate 56 are respectively limited on both sides of the rotating seat 51, so that the internal thread shaft 54 ​​can move and rotate within the rotating seat 51 without axial movement.

[0037] Advantageously, the inner threaded shaft 54 ​​has a threaded hole on its outer surface, and the second limiting plate 56 has a countersunk hole. A set screw is installed in the countersunk hole and threadedly connected to the threaded hole on the outer surface of the inner threaded shaft 54, so that the second limiting plate 56 can be connected and fixed to the inner threaded shaft 54.

[0038] Advantageously, the chute assembly includes a movable groove 61 disposed within the cover plate 12, and the telescopic plate 13 is slidably disposed within the movable groove 61.

[0039] Advantageously, a notch is provided on one side of the cover plate 12, and the telescopic plate 13 covers the notch after telescopic movement.

[0040] After the telescopic plate 13 covers the notch on one side of the cover plate 12 and flips the cover plate 12 to the front of the placement plate 11, the electronic drawing board 23 can be screen protected and the device can be carried as a whole, which is very convenient.

[0041] After flipping the cover plate 12 and the telescopic plate 13, first slide the telescopic plate 13 for adjustment, then snap the rectangular protrusion 33 at the end of the telescopic plate 13 into the groove 15, and then use the locking assembly to keep the telescopic plate 13 and the cover plate 12 relatively fixed. Since there are multiple grooves 15 and the shapes and angles are different, after snapping and abutting with the grooves 15 at different positions, the cover plate 12 and the placement plate 11 can be placed at multiple angles, allowing personnel to use the electronic drawing board 23 at an angle, which is very convenient for personnel to draw.

[0042] After the rectangular protrusion 33 at the end of the telescopic plate 13 is engaged and pressed against the groove 15, the operator rotates the rotating wheel 52 to drive the internal thread shaft 54 ​​to rotate. Since the thread shaft 55 is connected to the internal thread shaft 54 ​​through the threaded engagement, after the pressure block 58 is connected to the sliding groove 59 through the sliding engagement, the pressure block 58 is also driven to slide out of the sliding groove 59 and press and rub against the inner groove 57 to fix it, so that the cover plate 12, the guide rail 31 and the telescopic plate 13 remain relatively fixed.

[0043] Since the rectangular protrusion 33 and the groove 15 engage to form a blocking structure, the cover plate 12 and the telescopic plate 13 cannot rotate around the hinge point 41, thus realizing the function of keeping the cover plate 12 relatively fixed after the angle of the placement plate 11 is adjusted.

[0044] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the protection scope of this utility model; therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
