[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 2 The present invention provides an embodiment of a novel connection structure, comprising a beam-column 1, wherein the lower and upper surfaces of the beam-column 1 are both flat and can be placed directly on the ground. A connection component 2 is provided on the right side of the beam-column 1, which can assemble two sets of beam-columns 1 together.

[0032] Reference Figure 1 , Figure 2 , Figure 4 The connecting component 2 includes a support plate 21. A round rod 22 is fixedly connected to the lower surface of the support plate 21. The round rod 22 is located at the center of the lower surface of the support plate 21 and can position the support plate 21. A slot 201 is opened on the right surface of the beam-column 1. The slot 201 and the two ends of the support plate 21 fit together. A connecting plate 23 is inserted into the front surface of the beam-column 1. The connecting plate 23 is used to connect the beam-column 1 and the support plate 21. Positioning blocks 24 are fixedly connected to the left and right surfaces of the support plate 21. Multiple sets of positioning blocks 24 are arranged symmetrically. Positioning grooves 202 are opened on the upper and lower surfaces of the connecting plate 23. The positioning grooves 202 fit with the positioning blocks 24. When the support plate 21 and the beam-column 1 are inserted, the positioning blocks 24 and the positioning grooves 202 will be aligned when the connecting plate 23 and the beam-column 1 are inserted. A reinforcing component 3 is provided on the outer wall of the connecting plate 23. The reinforcing component 3 can provide support for the device.

[0033] Reference Figure 1 - Figure 3 The reinforcement component 3 includes a second beam-column 31, and a wedge 301 is provided on the upper surface of the connecting plate 23. The front-to-back spacing of the wedge 301 is the same as the front-to-back spacing of the second beam-column 31.

[0034] Reference Figure 1 , Figure 2 , Figure 4The support plate 21 is inserted into the inner wall of the slot 201. When the support plate 21 and the slot 201 are inserted, the upper and lower surfaces of the support plate 21 will contact the surface of the beam-column 1. The positioning block 24 is inserted into the inner wall of the slot 201. There are two sets of beam-column 1 and connecting plate 23. The two sets of beam-column 1 and connecting plate 23 are symmetrically distributed on the left and right sides with the center line of the support plate 21. The left and right sides of the round rod 22 are respectively attached to the opposite side of the two sets of beam-column 1. When the support plate 21 and the slot 201 are inserted, the round rod 22 will contact the surface of the beam-column 1, so that the support plate 21 cannot continue to extend into the support plate 21, thus achieving positioning. The positioning block 24 is set in L shape. The positioning block 24 is inserted into the inner wall of the positioning groove 202. When the positioning block 24 and the positioning groove 202 are inserted, the support plate 21 and the round rod 22 will be limited, and the support plate 21 cannot be removed from the beam-column 1 at this time.

[0035] Reference Figure 1 - Figure 3 The second beam 31 is set at an inclination. The top and bottom of the second beam 31 are both flat. The outer wall of the top of the second beam 31 is in contact with the top of the first beam 1. The connecting plate 23 penetrates the front surface of the second beam 31. The left and right surfaces of the connecting plate 23 are in contact with the inner wall of the second beam 31. The second beam 31 is inserted into the inner wall of the wedge 301, which can position the second beam 31 and ensure the stability of the device.

[0036] Working principle: When using this device, if the child needs to draw on the drawing board, the parent can assemble the drawing board support with the assistance of the parent.

[0037] During assembly, first remove the two beams and columns 1 and the support plate 21. Then, align the positioning blocks 24 at both ends of the support plate 21 with the slots 201 on the beams and columns 1 and insert them. When the surface of the round rod 22 contacts the surface of the beams and columns 1, hold the beams and columns 1 and the support plate 21. Then, take out the connecting plate 23 and insert it into the beams and columns 1 from the front and back. During insertion, the positioning grooves 202 and positioning blocks 24 on the connecting plate 23 will be aligned. As the connecting plate 23 is inserted, the positioning blocks 24 will gradually be inserted into the positioning grooves 202 to achieve a mortise and tenon connection. At this time, the support plate 21 and the round rod 22 will be limited. Similarly, the other side of the support plate 21 can be fixed to another set of beams and columns 1 to form a preliminary support structure.

[0038] Then, align beam and column 21 with connecting plate 23 and fit it onto the outer wall of connecting plate 23. During the fitting process, connecting plate 23 is in a lifted state. When it is aligned with the wedge 301 on connecting plate 23, release beam and column 21. It will fall under the influence of gravity and insert into wedge 301. At this time, connecting plate 23 and beam and column 21 will also be connected by mortise and tenon joint under the influence of the gravity of beam and column 21, forming a fixed connection.

[0039] Meanwhile, since beam and column 2 31 is set at an angle, it can form a triangle with beam and column 1 and beam and column 2 31, increasing the contact points with the ground and stability. Similarly, the remaining beam and column 2 31 can be installed on the connecting plate 23 in sequence to complete the assembly. Finally, the drawing board is placed flat on beam and column 1 and beam and column 2 31, and the child can operate it.

[0040] When disassembly is required, remove the drawing board, then move the second beam 31 upward to disengage it from the wedge 301, then remove the second beam 31 along the trajectory of the connecting plate 23, then pull the connecting plate 23 out of the first beam 1 to release the restriction on the support plate 21, and finally pull the support plate 21 out of the slot 201 to complete the disassembly.

[0041] The device's connection method makes it easy to assemble and disassemble, convenient to carry, and beneficial for developing children's hands-on skills.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
