Technical Field

[0001] This utility model relates to the field of children's drawing board technology, specifically a double-sided multifunctional children's drawing board. Background Technology

[0002] Children's drawing boards are writing tools for children to doodle, learn to draw, and learn numbers and Chinese characters. They include blackboards and whiteboards. Whiteboards are for drawing with whiteboard markers, and blackboards are for drawing with chalk. With the further development of technology, more and more electronic writing boards are being widely used in children's drawing boards.

[0003] However, existing electronic drawing board devices are usually installed on the drawing board frame in a fixed manner. Since the electronic screen of the electronic drawing board is relatively fragile, it is easy to be bumped and damaged when it is not in use. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a double-sided multi-functional children's drawing board that can be flipped over for protection when the electronic drawing board is not in use, so as to prevent it from being bumped or knocked.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a double-sided multifunctional children's drawing board, including a shelf, with figure-eight shaped support legs fixedly connected to both sides of the shelf, and drawing board frames arranged in an inverted V-shape slidably inserted into both sides of the figure-eight shaped support legs, with a fixing mechanism between the figure-eight shaped support legs and the drawing board frames, the drawing board frames including a first connecting plate and a second connecting plate hinged to each other, an electronic drawing board slidably connected between the first connecting plates on both sides, and a whiteboard fixedly connected between the second connecting plates on both sides;

[0006] The electronic drawing board has control cavities at both the top and bottom ends. The electronic drawing board has sliding holes on both sides that communicate with the control cavities. Sliding columns are slidably inserted into the sliding holes. The control cavities are equipped with control mechanisms that drive the sliding columns to slide. The inner walls of the first connecting plates on both sides are provided with strip-shaped flip grooves arranged along the length direction and cooperating with the sliding columns.

[0007] As an improvement, the control mechanism includes a gear rotatably connected to the center of the control cavity, a slider fixedly connected to one end of the slide column extending into the control cavity, a rack meshing with the gear fixedly connected to the end of the slider away from the slide column, the racks on both sides being centrally symmetrically arranged, and a knob for driving the gear to rotate on both sides of the electronic drawing board.

[0008] As an improvement, a stop block is fixedly connected to both sides of the control cavity, and a fixed spring is fixedly connected between the stop block and the slider.

[0009] As an improvement, the upper and lower ends of the strip-shaped flip groove are provided with interconnected turning grooves, and the turning grooves are provided with limiting slots that cooperate with the sliding column.

[0010] As an improvement, the fixing mechanism includes a fixing bolt threaded onto the figure-eight support leg, and both the first connecting plate and the second connecting plate are provided with fixing screw holes arranged along the length direction.

[0011] As an improvement, the shelf is equipped with a storage basket and a storage container.

[0012] The advantages of this invention compared to existing technologies are as follows: The electronic drawing boards and whiteboard on both sides allow children to doodle, learn to draw, and learn numbers and Chinese characters. During use, the sliding pillars at both ends of the electronic drawing board are engaged in corresponding strip-shaped flip grooves, allowing the electronic drawing board to be positioned between the first connecting plates on both sides. When the electronic drawing board needs to be flipped, the control mechanism drives two sliding pillars at one end to extend from the strip-shaped flip groove, driving the electronic drawing board 180 degrees before engaging the two sliding pillars back into the strip-shaped flip groove. At this point, the back of the electronic drawing board faces outwards, effectively preventing the screen from being damaged by bumps. Attached Figure Description

[0019] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 5 As shown, a double-sided multifunctional children's drawing board includes a shelf 1, on which a storage basket 16 and a storage jar 17 are provided. Both sides of the shelf 1 are fixedly connected to V-shaped support legs 2. Drawing board frames arranged in an inverted V-shape are slidably inserted into both sides of the V-shaped support legs. Fixing bolts 14 are threaded onto the V-shaped support legs. The first connecting plate 3 and the second connecting plate 4 are each provided with fixing screw holes 15 arranged along the length direction, allowing for vertical adjustment of the drawing board frame position to achieve height adjustment. After adjustment, the fixing bolts 14 are screwed into the fixing screw holes 15 to fix it. The drawing board frame includes a first connecting plate 3 and a second connecting plate 4 hinged together. An electronic drawing board 5 is slidably connected between the two sides of the first connecting plate 3, and a whiteboard 6 is fixedly connected between the two sides of the second connecting plate 4.

[0021] The electronic drawing board 5 has control cavities 18 at both its upper and lower ends. Sliding holes 13 communicating with the control cavities 18 are provided on both sides of the electronic drawing board 5. Sliding pins 7 are slidably inserted into each sliding hole 13. Gears 9 are rotatably connected to the centers of both the upper and lower control cavities 18. A slider 11 is fixedly connected to one end of each sliding pin 7 extending into the control cavity 18. A rack 10 meshing with the gear 9 is fixedly connected to the end of each slider 11 away from the sliding pin 7. The racks 10 on both sides are arranged symmetrically. Knobs 12 driving the gears 9 are provided on both sides of the electronic drawing board 5. Knobs 12 are fixedly connected to both sides of the control cavity 18. There is a stop block 19, and a fixing spring 20 is fixedly connected between the stop block 19 and the slider 11. The inner walls of the first connecting plates 3 on both sides are provided with strip-shaped flip grooves 8 arranged along the length direction and cooperating with the sliding column 7. The upper and lower ends of the strip-shaped flip grooves 8 are provided with interconnected turning grooves 21. The turning grooves 21 are provided with limiting slots 22 that cooperate with the sliding column 7, so that the strip-shaped flip grooves 8 on the left and right sides are respectively in the shape of "[" and "]". During use, the four sliding columns 7 of the electronic drawing board 5 are inserted into the corresponding limiting slots 22 under the elastic force of the fixing spring 20 to prevent the electronic drawing board 5 from moving.

[0022] In practical use, when the electronic drawing board 5 needs to be flipped, turning the knob 12 at the lower end drives the corresponding gear 9 to rotate. The gear 9 drives the racks 10 on both sides to move closer to each other. The racks 10 on both sides drive the sliders 11 on both sides to move closer to the stop block 19 along the inner wall of the control cavity 18, compressing the fixing springs 20 on both sides. The sliders 11 on both sides drive the sliding pillars 7 on both sides to extend out of the limiting slots 22 on both sides and into the sliding holes 13, pulling the electronic drawing board 5 outward, so that the sliding pillars 7 extend out of the strip flipping groove 8. At this time, the lower end of the electronic drawing board 5 is the movable end, and the upper end is still slidably connected between the first connecting plates 3 on both sides. Pulling the electronic drawing board 5 outward, the two sliding pillars 7 at the upper end first slide from the turning groove 21 into the strip flipping groove 8, and then pulling down the electronic drawing board 5... When the drawing board 5 is in operation, the sliding pillars 7 on both sides slide downwards along the strip-shaped flip grooves 8, and at the same time flip the electronic drawing board 5. After the electronic drawing board 5 is flipped 180 degrees, the movable end of the electronic drawing board 5 faces upwards. Turn the knob 12 again to drive the fixed pillars on both sides to extend into the sliding holes 13, and place the upper end of the electronic drawing board 5 between the strip-shaped flip grooves 8 on both sides. Release the knob 12, and under the restoring force of the fixed spring 20, the sliding pillars 7 on both sides insert into the strip-shaped flip grooves 8 on both sides, pressing the electronic drawing board 5 inwards. The electronic drawing board 5 drives the four sliding pillars 7 to slide into the turning groove 21. At the same time, under the restoring force of the fixed spring 20, the sliding pillars 7 insert into the corresponding limiting slots 22, realizing the limiting and fixing of the electronic drawing board 5. When the electronic drawing board 5 needs to be used again, the above operation can be repeated.
