[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0016] Such as Figures 1 to 3As shown in the figure, the utility model provides a splicable art drawing board, which includes: a drawing board body 1 and an extension board 2. The drawing board body 1 and the extension board 2 are both square boards. The extension board 2 is arranged on both sides of the drawing board body 1, and the edge parts of the drawing board body 1 and the extension board 2 are aligned with each other. The surfaces of the drawing board body 1 and the extension board 2 are aligned with each other. One side surface of the drawing board body 1 is used for drawing, and a connecting piece 3 is arranged on the other side surface. Connecting belts 11 are symmetrically arranged on the drawing board body 1. The connecting belts 11 are arranged along the edge where the drawing board body 1 and the extension board 2 are connected. Corresponding connecting belts 21 are arranged on the extension board 2. The connecting belts 11 and the connecting belts 21 are mutually clamped through the connecting piece 3.
[0017] Wherein, right trapezoidal protruding structures are respectively arranged on the connecting belts 11 and the connecting belts 21, and the protruding structures are respectively on the outer sides of the connecting belts 11 and the connecting belts 21. A trapezoidal connecting groove 31 is arranged in the connecting piece 3. The connecting groove 31 is stuck on the outer sides of the connecting belts 11 and the connecting belts 21 and is mutually engaged with the protruding structures. After the drawing board body 1 and the extension board 2 are butted, the cross-sectional contours of the connecting belts 11 and the connecting belts 21 form an inverted trapezoid, so as to be mutually buckled with the connecting groove 31 in the connecting piece 3 to realize clamping.
[0018] Wherein, a square strip-shaped filling block 32 is arranged in the connecting groove 31. The filling block 32 is arranged in the gap between the connecting belts 11 and the connecting belts 21 and is mutually abutted with the connecting belts 11 and the connecting belts 21. The filling block 32 mainly serves to fill the gap between the connecting belts 11 and the connecting belts 21, abut against the connecting belts 11 and the connecting belts 21, avoid their inward folding, and keep the stable placement of the extension board 2.
[0019] Wherein, support plates 33 are arranged on both sides of the connecting piece 3. A triangular reinforcing plate 34 is arranged between the support plates 33 and the connecting piece 3. Multiple groups of the reinforcing plates 34 are evenly arranged. The support plates 33 serve to support the extension board 2 and increase its placement stability. The arrangement of the reinforcing plates 34 serves to increase the structural strength between the support plates 33 and the connecting piece 3.
[0020] Wherein, a strip-shaped grip plate 35 is arranged on the side of the connecting piece 3 facing away from the drawing board body 1. Chamfers are arranged at the corners of the grip plate 35. Limit plates 12 and limit plates 22 are respectively arranged on the drawing board body 1 and the extension board 2. The limit plates 12 and the limit plates 22 are arranged at one end of the connecting piece 3 and are mutually stuck with the connecting piece 3. The grip plate 35 is convenient for the user to hold with the palm of the hand, so as to drive the whole connecting piece 3 to slide. The limit plates 12 and the limit plates 22 stick the connecting piece 3 from one end, so that it can only be installed and disassembled from the other end.
[0021] Among them, a plurality of groups of positioning holes 13 are evenly arranged on the side surface of the drawing board body 1 connected to the expansion board 2, and positioning pins 23 are correspondingly arranged on the expansion board 2. The positioning holes 13 and the positioning pins 23 are inserted into each other. The insertion of the positioning holes 13 and the positioning pins 23 can limit the drawing board body 1 and the expansion board 2, so that the two can only move along the axial direction of the positioning pins 23, and the sliding between the two is avoided. The movement in the axial direction is restricted by the connecting member 3, which is beneficial to maintaining the stability after connection.
