Description

Technical Field

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

[0002] A pen display tablet is a type of touch-screen computer drawing tablet. It has a screen that displays images and supports touch operation. Users can use a digital pen to draw and write on the screen. It can also connect to a computer via an interface to transmit user input signals. In existing technology, when drawing on a pen display tablet, the pen needs to be held continuously. When the artist's hands are prone to sweating, sweat can easily accumulate on the tablet during drawing and detailed work on specific areas. This sweat alters the friction between the pen and the tablet, making it difficult for the artist to control the strokes and causing the pen to slip, thus affecting the precision of line control. Therefore, this paper proposes a touch-screen computer drawing tablet to address these issues. Utility Model Content

[0003] The technical problem to be solved by this utility model overcomes the existing defects and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A touch-screen computer drawing board includes a digital drawing board with support frames at both its upper and lower ends. A support rod is slidably connected to the outer front end of the support frame, and a support block is slidably connected to the outer side of the support rod. A rotating block is rotatably connected to the front end of the support block, and a sponge pad is glued to the front end of the rotating block. A first toothed block is slidably connected to the inner front end of the support block, and a first toothed rack is provided at the rear end of the first toothed block. A fixed rod that is slidably connected to the support rod is fixedly connected to the rear end of the first toothed rack. A second toothed block that is slidably connected to the support rod is fixedly connected to the rear end of the fixed rod, and a second toothed rack that is fixedly connected to the support frame is provided at the rear end of the second toothed block.

[0006] As a further improvement of this utility model, a positioning threaded shaft is fixedly connected to the rear end of the rotating block, and the positioning threaded shaft is rotatably connected to the support block, and the positioning threaded shaft is helically connected to the first toothed block.

[0007] As a further improvement of this utility model, a spring is fixedly connected to the center of the rear end of the fixing rod, and the other end of the spring is fixedly connected to the support rod.

[0008] As a further improvement of this utility model, the inner rear end of the support frame is spirally connected to a fixed threaded shaft, and the outer side of the fixed threaded shaft is rotatably connected to a pressure plate, and there are 4 pressure plates.

[0009] As a further improvement of this utility model, both the front and rear ends of the digital drawing board are in contact with pads, and the pads are made of rubber. The pad at the front end is fixedly connected to the support frame, and the pad at the rear end is fixedly connected to the pressure plate.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. A touch-screen computer drawing tablet, comprising a support block, a strut, a support frame, a rotating block, a sponge pad, a first toothed block, a first rack, a second toothed block, and a second rack. When drawing with the device, the user controls the sliding of the support block and strut, and the sliding of the strut and support frame, by holding a digital pen. Alternatively, when meticulously drawing a fixed area, the rotating block rotates to position a threaded shaft that connects to the first toothed block, further engaging the first toothed block with the first rack. Simultaneously, a fixed rod drives the second toothed block to engage with the second rack, thus positioning the support block. When drawing with the handle resting on the sponge pad at the front of the rotating block, the support structure consisting of the support block, strut, and support frame supports the hand. The sponge pad absorbs sweat, preventing it from adhering to the drawing tablet and affecting friction between the pen and the tablet. This allows the user to better control the pen strokes and avoids affecting the precision of line control.

[0012] 2. A touch-screen computer drawing board, comprising a fixed threaded shaft, a pressure plate, a gasket, and a support frame, allows for drawing via a device. After placing the support frame at both ends of the drawing board, the fixed threaded shaft is screwed to the support frame. This further controls the pressure plate to drive the rear gasket into close contact with the drawing board, while simultaneously ensuring close contact between the front gasket of the support frame and the drawing board. This facilitates the addition of a handle auxiliary support structure to the outside of the drawing board, making operation simple and convenient. Attached Figure Description

[0019] Example 1

[0020] like Figure 1-3 As shown, a touch-screen computer drawing board includes a digital drawing board 1. Support frames 2 are in contact with both the upper and lower ends of the digital drawing board 1. A support rod 3 is slidably connected to the outer front end of the support frame 2. A support block 4 is slidably connected to the outer side of the support rod 3. A rotating block 5 is rotatably connected to the front end of the support block 4. A sponge pad 6 is glued to the front end of the rotating block 5. A first toothed block 8 is slidably connected to the inner front end of the support block 4. A first toothed rack 9 is provided at the rear end of the first toothed block 8. A fixed rod 10, slidably connected to the support rod 3, is fixedly connected to the rear end of the first toothed rack 9. A second toothed block 11, slidably connected to the support rod 3, is fixedly connected to the rear end of the fixed rod 10. A second toothed rack 12, fixedly connected to the support frame 2, is provided at the rear end of the second toothed block 11.

[0021] Example 2

[0022] like Figure 2 As shown, in order to solve the problem of inconvenience in controlling the positioning of the support block 4 when finely depicting a part of the painting, the rear end of the rotating block 5 is fixedly connected to a positioning threaded shaft 7, and the positioning threaded shaft 7 is rotatably connected to the support block 4. The positioning threaded shaft 7 is helically connected to the first toothed block 8. When finely depicting a part of the painting, the rotating block 5 drives the positioning threaded shaft 7 to helically connect with the first toothed block 8, further causing the first toothed block 8 to mesh with the first rack 9, and at the same time causing the second toothed block 11 to mesh with the second rack 12, which facilitates the control of the positioning of the support block 4.

[0023] Example 3

[0024] like Figure 2 As shown, in order to solve the problem that it is not easy to ensure that the second tooth block 11 does not contact the second rack 12 when the positioning support block 4 is not needed, a spring 13 is fixedly connected to the center of the rear end of the fixing rod 10, and the other end of the spring 13 is fixedly connected to the support rod 3. When the positioning support block 4 is not needed, the fixing rod 10 drives the second tooth block 11 away from the second rack 12 under the elastic force of the spring 13, which facilitates ensuring that the second tooth block 11 does not contact the second rack 12.

[0025] Example 4

[0026] like Figure 1-3 As shown, in order to solve the problem of the inconvenience of installing the handle auxiliary support structure on the outside of the digital screen drawing board 1, the inner rear end of the support frame 2 is screwed with a fixed threaded shaft 14, and the outside of the fixed threaded shaft 14 is rotatably connected with a pressure plate 15, and there are 4 pressure plates 15. After the support frame 2 is placed at the upper and lower ends of the digital screen drawing board 1, the fixed threaded shaft 14 is screwed to the support frame 2 by rotating, which further controls the pressure plate 15 to be close to the digital screen drawing board 1, making it convenient to install the handle auxiliary support structure on the outside of the digital screen drawing board 1.

[0027] Example 5

[0028] like Figure 2 As shown, in order to solve the problem that the digital drawing board 1 may be pinched when the handle auxiliary support structure is installed on the outside of the digital drawing board 1, both the front and rear ends of the digital drawing board 1 are in contact with pads 16, and the pads 16 are made of rubber. The front pad 16 is fixedly connected to the support frame 2, and the rear pad 16 is fixedly connected to the pressure plate 15. When the handle auxiliary support structure is installed on the outside of the digital drawing board 1, by making the support frame 2 and the pressure plate 15 both in contact with the digital drawing board 1 through the rubber pads 16, the digital drawing board 1 can be prevented from being pinched.

[0029] In this embodiment, when drawing using the device, first place the support frame 2 at both ends of the digital drawing board 1, then rotate the fixed threaded shaft 14 to connect it to the support frame 2. Further control the pressure plate 15 to drive the rubber pad 16 at the rear end to make close contact with the digital drawing board 1, and simultaneously make the pad 11 at the outer front end of the support frame 2 make close contact with the digital drawing board 1. At this time, a hand auxiliary support structure can be added to the outside of the digital drawing board 1. After completing the above operations, the device can be used. When drawing using the device, the hand is supported on the sponge pad 6 at the front end of the rotating block 5, and then the digital pen is held to control the sliding of the support block 4 and the support rod 3, and the sliding of the support rod 3 and the support frame 2. Drawing can then be performed. When making precise adjustments to a fixed position in the drawing... When drawing in detail, the rotating block 5 first drives the positioning threaded shaft 7 to connect with the first toothed block 8 in a spiral manner, further engaging the first toothed block 8 with the first rack 9. At the same time, the compression of the spring 13 by the fixing rod 10 drives the second toothed block 11 to engage with the second rack 12, thereby positioning the support block 4. The hand can be supported on the sponge pad 6 at the front end of the rotating block 5 for drawing. During the drawing process, the support structure composed of the support block 4, the support rod 3, and the support frame 2 supports the hand. With the absorption of sweat by the sponge pad 6, it can prevent sweat stains from adhering to the digital drawing tablet 1 during the drawing process, affecting the friction between the digital pen and the digital drawing tablet 1. This allows the artist to control the pen strokes well and avoids affecting the control accuracy of the lines.
