It should be noted that the terms "upper", "lower", "left", "right", "front", "back" and similar expressions used herein are only for the purpose of illustration and are not intended to limit the present invention.

[0070] A jigsaw puzzle toy comprises a plurality of jigsaw puzzle blocks, each of which is in an irregular shape, and the plurality of jigsaw puzzle blocks can be randomly assembled to form a plurality of different three-dimensional structures; each of the plurality of jigsaw puzzle blocks has a special-shaped body, and the body of each of the plurality of jigsaw puzzle blocks extends a plurality of convex parts in a direction away from the body, and the plurality of convex parts extend in different directions; each of the plurality of convex parts has a smooth end face; and some of the plurality of convex parts are provided with grooves, and the grooves are formed by the end faces of the corresponding convex parts being concave toward the body, and any two of the plurality of jigsaw puzzle blocks can be assembled or disassembled through the end faces.

[0071] In some embodiments, the groove is in the shape of an elongated strip and penetrates the protrusion in a direction parallel to the end surface.

[0072] In some embodiments, a dimension of an outer end of the groove away from the protrusion is smaller than a dimension of an inner end close to the protrusion.

[0073] In some embodiments, each convex portion of each of the multiple splicing blocks is provided with a groove. When the end faces of any two of the multiple splicing blocks are spliced, the grooves of the two end faces are symmetrical to each other along the splicing surfaces and form a accommodating cavity A which is wide at both ends and narrow in the middle. A pin 90 for connection is provided in the accommodating cavity A; the pin 90 is adapted to the accommodating cavity A and the outer surface of the pin 90 is in close contact with the inner surface of the accommodating cavity A.

[0074] like Figures 2 to 9 , Figures 20 to 27 As shown, each splicing block has a special-shaped body. The special-shaped mentioned in the present application refers to an irregular, non-standard shape, including an irregular curved surface. The splicing blocks of the present application can be formed by integral printing.

[0078] like Figure 5 As shown, it is a schematic diagram of the structure of the fourth splicing block 4. The fourth splicing block 4 has a main body 400, and the main body 400 is an irregular shape. The main body 400 of the fourth splicing block 4 extends in different directions to form a plurality of protrusions, including a first protrusion 401, a second protrusion 402, a third protrusion 403 and a fourth protrusion 404.

[0079] like Figure 6 As shown, it is a structural schematic diagram of the fifth splicing block 5, the fifth splicing block 5 has a main body 500, the main body 500 is an irregular shape, and the main body 500 of the fifth splicing block 5 extends in different directions to form a plurality of protrusions, including a first protrusion 501, a second protrusion 502, a third protrusion 503, a fourth protrusion 504, a fifth protrusion 505, a sixth protrusion 506 and a seventh protrusion 507.

[0080] like Figure 7 As shown, it is a structural schematic diagram of the sixth splicing block 6. The sixth splicing block 6 has a main body 600, and the main body 600 is an irregular shape. The main body 600 of the sixth splicing block 6 extends in different directions to form a plurality of protrusions, including a first protrusion 601, a second protrusion 602, a third protrusion 603, a fourth protrusion 604 and a fifth protrusion 605.

[0081] like Figure 8 As shown, it is a structural schematic diagram of the seventh splicing block 7. The seventh splicing block 7 has a main body 700, and the main body 700 is an irregular shape. The main body 700 of the seventh splicing block 7 extends in different directions to form a plurality of protrusions, including a first protrusion 701, a second protrusion 702, a third protrusion 703, a fourth protrusion 704 and a fifth protrusion 705.

[0082] like Fig. 9 As shown, it is a schematic diagram of the structure of the eighth splicing block 8. The eighth splicing block 8 has a main body 800, and the main body 800 is an irregular shape. The main body 800 of the eighth splicing block 8 extends in different directions to form a plurality of protrusions, including a first protrusion 801, a second protrusion 802, a third protrusion 803, a fourth protrusion 804, a fifth protrusion 805 and a sixth protrusion 806.

[0083] The end surface of each convex portion of all the convex portions of the first to eighth puzzle blocks 8 includes but is not limited to a circle, and may also be an ellipse or other shapes. The end surface of each convex portion is located in a different plane in space so as to be connected with other puzzle blocks; the end surface of each convex portion is concave toward the body to form a groove. Taking the first convex portion 101 of the first puzzle block 1 as an example, Figures 10 to 13 As shown, the end face of the first convex portion 101 is elliptical, and a portion of the end face of the first convex portion 101 is recessed toward the main body in a direction perpendicular to the end face to form a groove 111, the dimension of the outermost end of the groove 111 away from the main body 100 is b, and the dimension of the end of the groove 111 close to the main body 100 is a, wherein a<b, so that the groove 111 forms a wedge-shaped cross-section that is narrow outside and wide inside, so that the splicing block can be firmly connected by the latch 90 and ensure that the splicing block cannot move in a direction perpendicular to the cross-section; the groove 111 penetrates the first convex portion 101 in the radial direction of the end face, so that the latch 90 can be inserted into the groove from both sides.

[0084] When splicing Fig.10 As shown, the first protrusion 101 of the first assembly block 1 and the second protrusion 302 of the third assembly block 3 are butted, and the end surface of the first protrusion 101 and the end surface of the third protrusion 302 are butted, so that the groove 111 and the groove 321 are symmetrical about the butt surface and form an accommodating cavity A, so that the two ends of the accommodating cavity A along the left-right direction are larger than the size of the middle part; the interior of the accommodating cavity A is provided with a latch 90, as shown in FIG. Fig.12 As shown, the dimension a' at both ends of the latch 90 is larger than the dimension b' in the middle part, so that the latch 90 is adapted to the accommodating cavity A and the outer surface of the latch 90 is in close contact with the inner surface of the accommodating cavity A. The contact surface of the latch 90 and the accommodating cavity A generates friction, so that the two splicing blocks do not move naturally after being spliced, and a certain external force needs to be applied when disassembling. With the use of latch connection, each splicing block is free to be combined without direction restrictions. When adjusting the position of the splicing block, you only need to remove the latch connecting it to change the splicing shape, making the splicing more flexible and more convenient to fix.

[0085] The above eight splicing blocks can be arbitrarily combined to form different shapes, and the following embodiment is a splicing method of one of the shapes.

[0086] like Figure 1As shown, it is an exploded view of eight splicing blocks and one of their spliced ​​shapes. Specifically, the first convex portion 101 of the first splicing block 1 is connected to the second convex portion 302 of the third splicing block 3, the second convex portion 102 of the first splicing block 1 is connected to the third convex portion 703 of the seventh splicing block 7, the third convex portion 103 of the first splicing block 1 is connected to the third convex portion 203 of the second splicing block 2, the fourth convex portion 104 of the first splicing block 1 is connected to the second convex portion 202 of the second splicing block 2, the fifth convex portion 105 of the first splicing block 1 is connected to the fourth convex portion 204 of the second splicing block 2, and the sixth convex portion 106 of the first splicing block 1 is connected to the fourth convex portion 206 of the second splicing block 2.
