[0024] like Figures 1 to 5 As shown, the utility model provides a puzzle board, comprising a first box body 1 and a second box body 2 that are detachably connected; after the first box body 1 and the second box body 2 are connected to each other, the top surfaces of the two are coplanar; the first box body 1 has a first drawer 3 opened from the side edge that is not adjacent to the second box body 2, and the second box body 2 also has a second drawer 4 opened from the side edge that is not adjacent to the first box body 1; the first box body 1 has a first side edge 11 for connecting the second box body 2, and the first side edge 11 is formed with a first tenon 12 and a first tenon groove 13 distributed in parallel up and down; the second box body 2 has a second side edge corresponding to the first side edge 11 Along 21, the second side edge 21 is formed with a second tenon groove 23 corresponding to the first tenon 12 and a second tenon 22 corresponding to the first tenon groove 13; after the first box body 1 and the second box body 2 are connected to each other, the first tenon 12 is inserted into the second tenon groove 23, and the second tenon 22 is inserted into the first tenon groove 13; the first side edge 11 is provided with at least two connecting pins 5 extending toward the second side edge 21, and the second side edge 21 has a pin hole 201 for the connecting pin 5 to be inserted; the second box body 2 has a blind hole 202 orthogonal to the pin hole 201 from below, and a fastener 6 detachably connected to the connecting pin 5 is provided in the blind hole 202.

[0025] In the above technical solution, after the first box body 1 and the second box body 2 are connected, the first tenon 12, the first tenon groove 13, the second tenon 22, and the second tenon groove 23 cooperate to form a mutually embedded connection structure, and then the connection between the first box body 1 and the second box body 2 is locked by the connection pin 5 and the fastener 6. After the first box body 1 and the second box body 2 are connected to each other, the top surfaces of the two are coplanar to form a flat board surface, and the user can play the puzzle on this board. Moreover, the puzzle parts that have not been used can be temporarily stored in the first drawer 3 and the second drawer 4. In particular, when facing the shear force in the vertical direction, the mutually embedded connection structure of the first box body 1 and the second box body 2 is not easy to be accidentally separated, and the risk of fracture and damage of the connection structure will be significantly avoided.

[0026] In a preferred embodiment, Figure 1 As shown, the first box body 1 and the second box body 2 are each provided with two, the first box body 1 has two vertically connected first side edges 11, and the second box body 2 also has two vertically connected second side edges 21, and the two first box bodies 1 and the two second box bodies 2 are staggeredly distributed on the horizontal plane to form a matrix, so that the first side edges 11 correspond to the second side edges 21 one by one.

[0027] In a preferred embodiment, Figure 3 and Figure 5 As shown, the first tenon 12 is a wedge-shaped structure that gradually narrows toward the outer end, and the first mortise 13 is a wedge-shaped structure that gradually widens toward the outer end. The corresponding shape of the second tenon 22 is complementary to the first mortise 13, and the second mortise 23 is complementary to the first tenon 12.

[0028] In a preferred embodiment, Figure 6 As shown, the first side edge 11 is provided with at least two insertion holes 19 facing the second side edge 21, and the second side edge 21 has a guide rod 29 that is plugged and matched with the insertion holes 19 in a one-to-one correspondence, and the end of the guide rod 29 facing the insertion hole 19 is set to be conical or frustum. When splicing the first box body and the second box body, the cooperation between the guide rod 29 and the insertion hole 19 can effectively help the first side edge 11 and the second side edge 21 to be aligned, so that the splicing process is smoother. Especially for young users, the cooperation between the guide rod 29 and the insertion hole 19 can help them complete the adaptation accurately.

[0029] In a preferred embodiment, Figure 3 and Figure 5 As shown, the first side edge 11 has a first tenon 12 and two first tenon grooves 13, and the first tenon 12 and the first tenon grooves 13 are staggered up and down. Correspondingly, the second side edge 21 has two second tenons 22 and a second tenon groove 23, and the second tenons 22 and the second tenon grooves 23 are staggered up and down.

[0030] In a preferred embodiment, Figures 7 to 9 As shown, one end of the connecting pin 5 inserted into the pin hole 201 has a coaxially arranged annular groove 51; the fastener 6 is a cylinder that coaxially rotates and fits in the blind hole 202, the fastener 6 has a cavity 61 inside, and the cylindrical surface of the fastener 6 has a avoidance opening 62, and one side of the avoidance opening 62 has a bayonet 63 opened along the circumferential direction of the cylindrical surface of the fastener 6; when the fastener 6 is rotated so that the avoidance hole is opposite to the pin hole 201, the connecting pin 5 enters the cavity 61 of the fastener 6 through the pin hole 201 and the avoidance opening 62; when the fastener 6 is rotated so that the avoidance hole deviates from the pin hole 201, a section of the annular groove 51 of the connecting pin 5 is embedded in the bayonet 63, so that the connecting pin is temporarily locked, and the connection between the first box body 1 and the second box body 2 is also locked.

[0031] In particular, the cavity 61 inside the fastener 6 is eccentrically arranged; when the fastener 6 is rotated so that the avoidance hole is directly opposite to the pin hole 201, the cavity 61 is offset to the side closer to the pin hole 201 relative to the axis of the fastener 6; when the fastener 6 is rotated so that the avoidance hole deviates from the pin hole 201, the cavity 61 is offset to the side away from the pin hole 201 relative to the axis of the fastener 6, and an axial pulling force is applied to the connecting pin 5 through the cooperation of the bayonet 63 and the annular groove 51, so that the connection between the first box body 1 and the second box body 2 is locked, and the connection is tight enough. Obviously, when the first box body 1 and the second box body 2 need to be separated, it is only necessary to rotate the fastener 6 so that the avoidance hole is directly opposite to the pin hole 201, so as to eliminate the aforementioned axial pulling force applied to the connecting pin 5, and the first box body 1 and the second box body 2 can be easily separated. For those skilled in the art, the protection scope of the present invention is not limited to the details of the above-mentioned exemplary embodiments. Without departing from the spirit or basic characteristics of the present invention, the equivalent meanings and all changes in the protection scope made by those skilled in the art based on the requirements of the present invention should be included in the present invention.
