[0049] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0050] Example:

[0051] like Figure 1-Figure 16As shown, the children's drawing board includes two drawing board frame assemblies symmetrically arranged front and back, and a storage tray 3 is provided between the two drawing board frame assemblies. The drawing board frame assembly includes a drawing board frame 1, a drawing board body 6, a first leg, and a second leg. The leg structures are the same and are recorded as legs 4 for ease of description. A rectangular through hole 38 is provided in the drawing board frame 1, and the rectangular through hole 38 is used to accommodate the drawing board body 6. The two drawing board frame assemblies are connected by a hinge arranged at the top (not shown, the hinge is the prior art). A pair of hinges are provided, one on the left and one on the right, to achieve a stable connection. When assembled and used, the two drawing board frame assemblies can be relatively opened, and can be folded side by side when needed. Based on the fact that the structural forms of the two drawing board frame assemblies are the same, the following description is mainly based on the drawing board assembly on the front side as an example.

[0052] Figure 3 As shown, two convex columns are respectively arranged on the left and right sides of the drawing board 6, the upper convex column is defined as the upper convex column 63, and the lower convex column is positioned as the lower convex column 64, and the convex column is cylindrical. The drawing board 6 includes a main board and a peripheral sub-frame 62. The drawing board 6 installed on the front and rear sides is different in that the main board on the front side is a blackboard 61, and the other side is a whiteboard 2, that is, the material of some of the main board bodies is different, and the basic structure is the same. The sub-frames 62 on the front and rear sides are the same, both of which are rectangular frames. The blackboard 61 and the whiteboard 2 are also concepts in the prior art, that is, the main components of the double-sided drawing board. The material and principle of the main board body belong to the prior art. The blackboard 61 includes a green board surface, a galvanized iron plate, a fiberboard, and a moisture-proof layer arranged in sequence. The surroundings of the blackboard 61 are embedded in the sub-frame 62. The setting of the galvanized iron plate can realize the magnetic attraction function, so that the blackboard 61 surface can absorb magnets for pressing drawing paper, and the green board surface is for chalk writing. Accordingly, the only difference between the whiteboard 2 and the blackboard 61 is that the whiteboard surface replaces the green board surface for writing with a whiteboard pen.

[0053] The upper protrusion 63 and the lower protrusion 64 are both arranged on the sub-frame 62 and are both made of wood.

[0054] Figure 4-6 As shown, a set of drawing board fixing structures are respectively provided on the left and right sides of the drawing board frame 1, and the two sets of drawing board fixing structures are symmetrically arranged. The drawing board fixing structures include a rotation limit groove 15 on the upper side and a stop groove 17 on the lower side. The upper boss 63 and the lower boss 64 cooperate with the rotation limit groove 15 and the stop groove 17 respectively. The drawing board 6 is loaded from the front side of the drawing board frame 1. After the upper boss 63 enters the rotation limit groove 15, it is hinged with it and can rotate relatively under the action of external force; after the lower boss 64 enters the stop groove 17, the stop groove 17 limits the backward movement of the lower boss 64.

[0055] The drawing board frame 1 is composed of a top rod 13, a left rod 11, a right rod 12, and a bottom rod 14, and encloses the rectangular through hole 38. The lower ends of the left rod 11 and the right rod 12 extend downward from the bottom rod 14. The rotation limit groove 15 and the stop groove 17 are both located between the top rod 13 and the bottom rod 14. The rotation limit groove 15 is composed of an entry and exit groove 151 and a hinge groove 152. The hinge groove 152 is located below the entry and exit groove 151 and the two are connected. The entry and exit groove 151 is for the upper boss 63 to be installed or withdrawn, and the hinge groove 152 is an arc groove for the upper boss 63 to rotate. When installing the drawing board body 6, the upper part is installed first, that is, the upper boss 63 enters the entry and exit groove 151 first, and then moves slightly downward to enter the hinge groove 152, and the lower boss 64 of the drawing board body 6 is stuck in the stop groove 17. Generally, when in use, the drawing board body 6 is tilted, and relying on the gravity of the drawing board body 6, the drawing board body 6 is in a stable state.

[0056] A support member 7 is provided on the left and right side walls of the rectangular through hole 38 of the drawing board frame 1. Figure 7 As shown, one end of the support member 7 has a plug-in shaft 71, and the other end is a support portion 72. The support member 7 includes a strip-shaped portion and the plug-in shaft 71 perpendicular to the end thereof, and the other end of the strip-shaped portion forms a toothed support portion 72.

[0057] When the drawing board body 6 does not need to adjust the angle, the support member 7 is hidden and assembled in the drawing board frame 1. The inner wall of the drawing board frame 1 is provided with a hidden groove 16, and the hidden groove 16 is for the support member 7 to be inserted. The hidden groove 16 includes a round hole groove 161 and a strip groove 162. The depth of the strip groove 162 is less than the depth of the round hole groove 161. The round hole groove 161 is for the insertion of the plug-in shaft 71, and the strip groove 162 is for the strip portion to be inserted, so that the installed support member 7 does not protrude from the inner wall of the drawing board frame 1, and does not interfere with its rotation when the drawing board body 6 rotates. After the support member 7 is installed, as shown in FIG. Fig. 9 shown.

[0058] When the drawing board 6 is adjusted in angle, the upper boss 63 of the drawing board 6 is used as the rotation axis to rotate, the lower boss 64 of the drawing board 6 leaves the stop groove 17, the plug-in shaft 71 of the support member 7 moves out axially for a distance and rotates so that the support portion 72 abuts against the lower side of the drawing board 6, and the abutting position is selected according to the required angle of the drawing board 6. The plug-in shaft 71 at this point moves out axially for a distance, but does not escape from the circular hole groove 161 of the hidden groove 16, and the plug-in shaft 71 can be rotated. In order to facilitate the axial removal of the support member 7, the length of the strip groove 162 is greater than the length of the strip portion of the support member 7, and a space is left at the bottom.

[0059] Further, Figure 8 As shown, a rack-shaped structure 65 is provided on the side of the drawing board body 6, which has a plurality of tooth grooves, and is selectively matched with the supporting portion 72 of the supporting member 7 to support the drawing board body 6 after the drawing board body 6 is turned over. Fig.10, which is a schematic diagram showing that the front drawing board 6 is supported by the support member 7 at a certain angle.

[0060] Figure 1 and 14 As shown, the drawing board frame 1 is connected to two legs 4, and the two legs 4 are respectively matched with the left rod 11 and the right rod 12. Figure 4 As shown, two bolt holes 18 are provided on the portions of the left rod 11 and the right rod 12 extending out of the bottom rod 14 . Figure 10-12 As shown, a T-shaped slot is provided on the leg 4, the opening of the T-shaped slot faces one side of the drawing board frame 1, and the length direction of the T-shaped slot is arranged along the length direction of the leg 4. The T-shaped slot is used to install a bolt 8, and the threaded section 83 of the bolt 8 passes through and extends out of the bolt hole 18, and a nut 5 is threadedly connected to one end of the bolt 8, and the nut 5 can be an existing butterfly nut or a plum nut.

[0061] The left rod 11 and the right rod 12 are both rectangular rods with the same structure. The leg 4 is on the upper side of the left rod 11 and the right rod 12, and the leg 4 is a rectangular rod. The width of the leg 4 is smaller than the left rod 11. The left side of the leg 4 located on the left is aligned with the left side of the left rod 11, and the right side of the leg 4 located on the right is aligned with the right side of the right rod 12. The above-mentioned rotation limit groove 15 and the stop groove 17 are just set on the part of the left rod 11 and the right rod 12 that is wider than the leg 4. The structure is compact, and the leg 4 will not interfere with the movement of the lower boss 64.

[0062] Fig.15 As shown, the bolt 8 includes a polished rod section 81 and a threaded section 83. The polished rod section 81 is provided with a hexagonal or quadrangular prism-shaped anti-rotation section 82. The T-shaped groove is composed of a first groove 411 and a second groove 412 that are connected to each other. The width of the first groove 411 is greater than that of the second groove 412. The anti-rotation section 82 is located in the first groove 411, the polished rod section 81 is located in the second groove 412, and the threaded section passes through the second groove 412 and extends out of the second groove 412. The threaded section 83 is used to cooperate with the nut 5.

[0063] When adjusting the height of the drawing board, it is achieved by adjusting the fixed position of the leg 4. The leg 4 is moved to the required position along its length direction and locked with the nut 5. When tightening the nut 5, since the bolt 8 cannot rotate, the nut 5 can be manually screwed alone, which is simple to operate. During the movement, the bolt 8 does not move; the leg 4 is also a wooden structure. When processing the T-slot, the inner wall is processed to be smoother, which is conducive to smooth movement and prevents the bolt 8 from getting stuck. Fig.13As shown, one end of the T-slot is specially provided with an insertion port 413, the diameter of which is equivalent to the width of the first slot 411, for the locking section 82 of the bolt 8 to be inserted, because the width of the second slot 412 of the T-slot is smaller than the outer diameter of the locking section 82. The T-slot cooperates with the bolt 8, and when the bolt 8 is inserted into the T-slot, it will not automatically fall out easily, and the bolt 8 is hidden, and the nut 5 matched with it is located at the lower side of the drawing board frame 1, which is also more beautiful.

[0064] Figure 4 As shown, a pin hole 19 is provided on the part of the left rod 11 and the right rod 12 extending out of the bottom rod 14, and the center line of the pin hole 19 is perpendicular to the center line direction of the bolt hole 18. The pin hole 19 is used for the pin to pass through, and is used to install the storage tray 3. The storage tray 3 is provided with four through holes 38, respectively for four pins to pass through. In this embodiment, the pin is a wooden cylinder with chamfered ends for easy insertion.

[0065] Fig.17 As shown, the storage tray 3 is surrounded by a bottom plate 37, a left side plate 32, a right side plate 34, a rear side plate 36, and a front side plate 31 to form a cavity structure with an opening facing upward. The above-mentioned pin holes 19 are respectively arranged on the left side plate 32 and the right side plate 34. The front side plate 31 and the rear side plate 36 are arranged symmetrically in front and back, and the left side plate 32 and the right side plate 34 are arranged symmetrically in left and right. After the storage tray 3 is installed and fixed by four pins, the angle of the two drawing board frames 1 is limited. When viewed from the side, it is an A-shaped stable structure that is not easy to tip over.

[0066] The height of the front side plate 31 is lower than the height of the left side plate 32, which is convenient for picking up and placing things. The middle part of the front side plate 31 is convex backward and forms an arc-shaped giving way portion 311, and the painter can lean forward when necessary to give way to the body.

[0067] The bottom plate 37 is provided with a partition 33, and there are two partitions 33. The length direction of the partition 33 is arranged along the left-right direction, and one of the partitions 33 contacts the yielding portion 311 of the front side plate 31. A storage box is formed between the partitions 33 to place the necessary things. A slot plate 39 is also provided between the partition 33 and the front side plate 31. The slot plate 39 is arranged along the front-back direction. A blackboard eraser placement groove 35 is formed between the slot plate 39, the partition 33, the front side plate 31, and the left side plate 32 or the right side plate 34. The blackboard eraser placement groove 35 can hold water; the other partition 33 contacts the yielding portion 311 of the front side plate 31. The blackboard eraser placement groove 35 is specially provided, and some water can be placed. It is for wiping the blackboard 61. Now, dust-free chalk is mostly used, and a wet blackboard eraser is required. Of course, this can be used flexibly according to needs, and it is not necessary to put water, and it can be directly used to place the blackboard 61 for wiping. There are two blackboard eraser placement grooves, and one can also be used to put a dry blackboard eraser and the other to put a wet blackboard eraser. The structure formed at the rear side plate 36 and the partition plate 33 is different from that at the front side, because the rear side corresponds to the whiteboard 2 and can be wiped with a soft cloth or flannel.

[0068] The above structural design has the functions of a double-sided drawing board of a blackboard and a whiteboard, and also has the function of adjusting the drawing board height (to adapt to users of different heights), and the function of adjusting the angle of the drawing board body 6 (the blackboard and the whiteboard can be adjusted independently), which can well meet the use requirements. Although the angle can be adjusted within a certain range, the drawing board body 6 is still in a tilted state. The following optimizations have been made, and the product can be selected according to needs.

[0069] Further, Fig.18 and 19 As shown, a vertical stop plate 9 is provided on the left side plate 32 and the right side plate 34 respectively, and two stopper slots 91 are provided on the upper part of the vertical stop plate 9. The two stopper slots 91 on the same vertical stop plate 9 are arranged at intervals in front and back. When the drawing board body 6 is adjusted to a vertical state, the stopper slots 91 are used to be locked with the lower protrusion 64 of the drawing board body 6. The vertical state here includes a state approximately vertical.

[0070] The vertical limit plate 9 is fixed to the outer side of the storage tray 3 by a hinge. When the vertical limit plate 9 is not needed, it can be rotated inward and placed basically flat on the upper side of the storage box of the storage tray, or flipped to the other side. If it is designed to be fixed, it will protrude upward and take up space, and it is not conducive to folding and storage. When the vertical limit plate 9 is needed, it is rotated to the vertical direction and cooperates with the lower protrusion 64 of the painting body to make the painting board body 6 basically in a vertical state. The caliber of the limit bayonet 91 and the outer diameter of the lower protrusion 64 have a smaller gap, so that there is friction when it is inserted, and the stability is better; relying on the gravity of the painting board body 6, the stability is better. The painting board body is in a vertical state and can be used in children's teaching scenes or other scenes required by users.

[0071] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
