[0033] In an embodiment of the present utility model, two pads 1 are used to fix the position of the folding mechanism 2, and the folding mechanism 2 is used to drive the splicing mechanism 3 to fold, so as to facilitate the adjustment of the angle of the drawing board when it is used. The two moving wheels 4 and the telescopic pull rod 5 are used in combination to improve the portability of the drawing board, facilitate the movement of the drawing board, and make it more convenient to use.

[0034] In some embodiments, as Figure 5-7 As shown, as a preferred embodiment of the present invention, the splicing mechanism 3 includes three drawing board bodies 31, the outer surfaces of the three drawing board bodies 31 are slidably connected with a splicing assembly 32, the lower end of the splicing assembly 32 is fixedly connected with a rotating block 36, the inner surface of the rotating block 36 is fixedly connected to the outer surface of the rotating rod 25, the front end of the splicing assembly 32 is fixedly connected with a lock buckle 35, the rear end of the splicing assembly 32 is fixedly connected with a hinge 33, and the front end of the hinge 33 is fixedly connected with a locking assembly 34.

[0036] The locking assembly 34 includes a limit plate 341, the front end of the limit plate 341 is fixedly connected to a connecting plate 342, the left end of the connecting plate 342 is fixedly connected to a telescopic slot 343, the inner surface of the telescopic slot 343 is slidably connected to two locking tongues 344, and the ends of the two locking tongues 344 close to each other are fixedly connected to a spring 345.

[0037] In the embodiment of the present invention, by pressing the two locking tongues 344 inward at the same time and pulling them out to the right, the limiting plate 341 can be rotated with the cooperation of the hinge 33. At this time, the inner cavity of the storage box 321 will be exposed, and the three drawing board bodies 31 can be taken out from it. The three drawing board bodies 31 are inserted into the inner surfaces of the two splicing grooves 322 in sequence, and the three drawing board bodies 31 are spliced ​​together. After the splicing is completed, the limiting plate 341 is rotated to the left. In this process, the two locking tongues 344 The two locking tongues 344 will pass through the lock buckle 35. When passing through, the two locking tongues 344 will slide toward the inside of the telescopic slot 343 under the action of the inner surface of the lock buckle 35. At this time, the spring 345 will be squeezed. At the moment when the two locking tongues 344 pass through the lock buckle 35, the two locking tongues 344 will pop out to the upper and lower sides under the action of the spring 345 and get stuck at the left end of the lock buckle 35. At this time, the three drawing board bodies 31 will be fixed under the joint action of the limiting plate 341 and the storage box 321, so that the splicing of the drawing boards can be completed.

[0038] In some embodiments, as Figure 2-4 As shown, as a preferred embodiment of the present invention, the folding mechanism 2 includes a knob 21, a screw rod 22 is fixedly connected to the front end of the knob 21, and the outer surface of the screw rod 22 is rotatably connected to two positioning plates 23, the left and right ends of the positioning plate 23 located at the rear side are respectively fixedly connected to the ends of the two pads 1 close to each other, and the left and right ends of the positioning plate 23 located at the front side are fixedly connected to support plates 24, the ends of the two support plates 24 away from each other are respectively fixedly connected to the ends of the two pads 1 close to each other, the inner surfaces of the two support plates 24 are commonly fixedly connected to a rotating rod 25, the ends of the two positioning plates 23 close to each other are commonly fixedly connected to a guide plate 26, and the outer surface of the screw rod 22 is threadedly connected to a folding component 27.

[0039] The folding assembly 27 includes a sliding plate 271, the inner surface of the sliding plate 271 is slidably connected to the outer surface of the guide plate 26, the lower end of the sliding plate 271 is fixedly connected to a moving block 272, the inner surface of the moving block 272 is threadedly connected to the outer surface of the screw rod 22, the upper end of the sliding plate 271 is fixedly connected to a rotating seat 273, and the outer surface of the rotating seat 273 is rotatably connected to a flip plate 274.

[0040] In the embodiment of the present invention, by rotating the knob 21, the screw rod 22 can rotate on the inner surfaces of the two positioning plates 23 under the action of the knob 21. When the screw rod 22 rotates, it will drive the moving block 272 to move forward. When the moving block 272 moves forward, it will carry the sliding plate 271 forward along the outer surface of the guide plate 26. In this process, the angle between the flip plate 274 and the sliding plate 271 will become larger and larger. Because the outer surface of the rotating seat 22 323 is rotatably connected to the inner surface of the flip plate 274, and the inner surface of the rotating block 36 is fixedly connected to the outer surface of the rotating rod 25, the storage box 321 will be under the action of the flip plate 274 and with the cooperation of the rotating block 36, it will rotate with the rotating rod 25 as the axis to realize the folding of the drawing board, and the angle of the drawing board when in use can be adjusted.

[0041] Working principle: When you need to use the drawing board, you can use the two moving wheels 4 and the telescopic pull rod 5 to move the drawing board to the position where it is used, which can improve the portability of the drawing board. Then, press the two locking tongues 344 inward at the same time and pull them out to the right, so that the limit plate 341 can rotate with the cooperation of the hinge 33. At this time, the inner cavity of the storage box 321 will be exposed, and you can take out the three drawing board bodies 31 from it, and insert the three drawing board bodies 31 into the inner surfaces of the two splicing grooves 322 in turn, and splice the three drawing board bodies 31 together. After the splicing is completed, the limit plate 341 is pulled out. The board 341 rotates to the left, and during this process the two locking tongues 344 will pass through the lock buckle 35. When passing through, the two locking tongues 344 will slide toward the inside of the telescopic slot 343 under the action of the inner surface of the lock buckle 35. At this time, the spring 345 will be squeezed. At the moment when the two locking tongues 344 pass through the lock buckle 35, the two locking tongues 344 will pop out to the upper and lower sides under the action of the spring 345 and get stuck at the left end of the lock buckle 35. At this time, the three drawing board bodies 31 will be fixed under the joint action of the limiting plate 341 and the storage box 321, so that the splicing of the drawing boards can be completed.

[0042] After the splicing is completed, turn the knob 21 so that the screw rod 22 can rotate on the inner surfaces of the two positioning plates 23 under the action of the knob 21. When the screw rod 22 rotates, it will drive the moving block 272 to move forward. When the moving block 272 moves forward, it will move the sliding plate 271 forward along the outer surface of the guide plate 26. In this process, the angle between the flip plate 274 and the sliding plate 271 will become larger and larger. Under the action of the flip plate 274 and with the cooperation of the rotating block 36, the storage box 321 will rotate with the rotating rod 25 as the axis to realize the folding of the drawing board, and the angle of the drawing board when in use can be adjusted.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
