The utility model provides a jigsaw puzzle.

Referring to fig. 1 and 2 in combination, in an embodiment of the present invention, the jigsaw puzzle includes a main body seat 10 and a plurality of puzzle pieces 50. The main body seat 10 is provided with at least two connected splicing surfaces 10a with included angles, and the included angles of the two adjacent splicing surfaces 10a are arranged in a non-flat angle; each splicing surface 10a is detachably provided with a plurality of splicing pieces 50, the plurality of splicing pieces 50 can slide relative to the main body seat 10 and move in the same splicing surface 10a or between different splicing surfaces 10a, and the splicing patterns are formed on the surfaces of the splicing pieces 50, which face away from the main body seat 10.

In an embodiment of the present invention, the main body seat 10 is used for installing a plurality of tiles 50, and forms a splicing surface 10a, so that the plurality of tiles 50 can be spliced on a three-dimensional surface. The shape of the splicing piece can be a cube, a cuboid, other cubes, a cylinder or a sphere (at the moment, two hemispherical surfaces of the splicing piece 50 can form splicing surfaces 10a of the two), and the like, the concrete shape of the main body seat 10 is not limited and determined, and the splicing piece 50 can be guaranteed to slide between different splicing surfaces 10a of the main body seat 10. The main body seat 10 may be made of plastic, for example: ABS, POM, PS, PMMA, PC, PET, etc. to reduce the mass of the main body stand 10 for easy portability. Of course, the main body seat 10 may be made of metal, such as: the main body seat 10 is made of aluminum materials, aluminum alloy materials, copper alloy materials, iron materials and stainless steel materials, so that the strength of the main body seat 10 is improved, and the service life is prolonged. The non-straight angle setting of the included angle between two adjacent splicing surfaces 10a is as follows: the included angle may be an acute angle, a right angle, or an obtuse angle, so as to realize that the puzzle 50 has a three-dimensional puzzle function. The tiles 50 are mainly used for sliding relative to the main body seat 10 when being driven, and since the surface of each tile 50 facing away from the splicing surface 10a is formed with a partial splicing pattern of the complete splicing pattern, when each tile 50 slides to a preset position, the partial splicing pattern on each tile 50 can be spliced into the complete splicing pattern. It should be noted that the complete mosaic pattern can be in one pattern form, but the complete mosaic pattern can also be in two or more patterns to increase the diversity of mosaic of tiles 50. The driven form of the segment 50 is pushed by the user to slide relative to the main body seat 10, the segment 50 may be square or rectangular, and the specific shape of the segment 50 is not limited in this application, so that the segment can slide when pushed by the user. Wherein the splicing pattern can be attached to the segment 50 through a carrier plate printed with a pattern by glue, so as to simplify the connection structure between the splicing pattern and the segment 50 and ensure the stability of the fixation of the splicing pattern. Of course, in order to further increase the variety of patterns that can be stitched by the puzzle, the stitching pattern can also be magnetically affixed to the tile 50 by a carrier plate printed with a pattern. Thus, when the jigsaw puzzle is used for a long period of time and the interest is reduced, the splicing pattern of the jigsaw puzzle 50 can be changed by replacing the carrier plate printed with different patterns on the jigsaw puzzle 50 without replacing the whole jigsaw puzzle. And the magnetic attraction fixation can simplify the disassembly and assembly process of the carrier plate and the splicing block and improve the convenience in the splicing pattern replacement process.

The technical scheme of the utility model jigsaw puzzle when using, promote each piece 50 through external force and slide in the same concatenation face 10a of main part seat 10 or between different concatenation faces 10a, can make each piece 50 deviate from the concatenation pattern on concatenation surface and can splice the complete pattern that forms and predetermine to realized the picture arragement on solid surface, in order to temper user's three-dimensional thinking. Moreover, since the segments 50 of the jigsaw puzzle in this embodiment are slidably disposed on each of the splicing surfaces 10a of the main body seat 10, the plurality of segments 50 and the main body form a whole during the splicing process. Compared with the prior art in which the plurality of segments 50 are fixed on the surface of the main body base 10 one by means of the buckles 211 or the magnetic attraction, the plurality of segments 50 and the main body are independent during the splicing process. The jigsaw puzzle in the scheme can effectively reduce the possibility that jigsaw parts are lost in the splicing process, thereby improving the convenience of the jigsaw puzzle in the using process.

Further, the plurality of segments 50 of the puzzle according to the present embodiment are detachably coupled to the main body housing 10, so that a part of the segments 50 can be detached from the main body housing 10 for replacement when it is damaged and needs to be replaced. This avoids partial damage to the tiles 50 and requires replacement of the puzzle as a whole, thereby reducing the cost of replacement of the puzzle.

Referring to fig. 1, fig. 2, fig. 3 and fig. 4, in an embodiment of the present invention, two adjacent splicing surfaces 10a are provided with a plurality of chutes 10b that are communicated with each other, and the chutes 10b form a sliding path of the splicing block 50; the surface of the segment 50 facing away from the splicing pattern is provided with a sliding block 51, and the sliding block 51 can be elastically clamped into or separated from the sliding groove 10b, so that the segment 50 can be detachably connected to the main body seat 10.

It can be understood that the sliding stability of the split 50 during the splicing process is ensured by the guiding cooperation of the sliding slot 10b and the sliding block 51, so that the split 50 can only slide along the sliding path formed by the sliding slot 10 b. The plurality of sliding grooves 10b formed on each splicing surface 10a may extend in a first direction and a second direction, and the first direction and the second direction may be linear and perpendicular to each other. And the segment 50 can be elastically snapped into or out of the sliding groove 10b by the slider 51 so as to be detachably connected to the main body base 10. The sliding block 51 has both guiding and connecting functions, so that there is no need to provide additional connecting structure on the segment 50 to limit and fix it to the main body seat 10, thereby simplifying the connecting structure between the segment 50 and the main body seat 10. And the elastic force of the sliding block 51 is clamped, so that the assembly process between the sliding block 51 and the main body seat 10 can be simplified. In addition, it should be noted that the present application is not limited to this, and in other embodiments, two adjacent splicing surfaces 10a may be provided with the sliding blocks 51, and the surfaces of the splicing blocks 50 facing the splicing surfaces 10a may be provided with the mutually communicated sliding grooves 10 b. Or, the splicing surface 10a is embedded with a magnetic film, and the splicing blocks 50 are embedded with magnetic blocks capable of being attracted to the magnetic film, so that the splicing surfaces 10a of the main body seat 10 can be magnetically fixed to the splicing blocks 50, and can slide relative to the main body seat 10 when driven by external force of a user.

In an embodiment of the present invention, the slider 51 is disposed in an inverted T shape on a longitudinal section perpendicular to the extending direction of the sliding groove 10b, and the shape of the sliding groove 10b is adapted to the shape of the slider 51.

It can be understood that the arrangement can increase the contact area between the sliding block 51 and the sliding slot 10b, thereby improving the connection stability between the sliding block 51 and the sliding slot 10b, and further reducing the possibility that the sliding block 51 is separated from the sliding slot 10b during the use of the jigsaw puzzle, so that the tile 50 is separated from the main body base 10. The sliding block 51 comprises a sliding block main body portion 511 and a sliding block connecting portion 513, the projection area of the main body portion 511 on the splicing surface 10a is larger than the projection area of the sliding block connecting portion 513 on the splicing surface 10a, so that the sliding block 51 roughly forms an inverted T shape, the sliding block main body portion 511 is embedded in the sliding groove 10b and abuts against the groove wall of the sliding groove 10b, one end of the sliding block connecting portion 513 is inserted into the sliding groove 10b and connected with the sliding main body portion, and the other end of the sliding block connecting portion 513 is exposed out of the sliding groove 10b and connected with the splicing block 50. In order to facilitate the fitting of the shapes of the slider 51 and the respective slide grooves 10b, the slider main body portion 511 may be provided in a square shape so as to be circumferentially uniform. Of course, the slider main body portion 511 may be provided in a circular shape. In order to improve the smoothness of the sliding of the slider 51 in the slide groove 10b, the slider connecting portion 513 may be provided in a cylindrical shape to reduce the contact area between the sliding connecting portion and the groove side wall of the slide groove 10b and to reduce the friction force generated by the relative sliding between the sliding connecting portion and the groove side wall. Of course, the cross-sectional shape of the slider connecting portion 513 may be square. In other embodiments, the slider 51 may be provided in a dovetail shape in a vertical cross section perpendicular to the extending direction of the slide groove 10b, and the shape of the slide groove 10b may be adapted to the shape of the slider 51.

Referring to fig. 1, fig. 2 and fig. 4, in an embodiment of the present invention, the main body seat 10 includes a main body frame 100 and a plurality of first bumps 200; the main body frame 100 is arranged in a cube or a cuboid and is provided with six splicing surfaces 10 a; some of the first bumps 200 are disposed at intervals on each of the splicing surfaces 10a, and the other part of the first bumps is disposed at intervals on the edge formed by two adjacent splicing surfaces 10a, and each two adjacent first bumps 200 and the splicing surfaces 10a cooperate to form a sliding slot 10 b.

It can be understood that the main body frame 100 is a cube or a cuboid, so that the shape thereof is regular, and the uniform rectangular array distribution of the splicing blocks 50 arranged on the splicing surfaces 10a can be facilitated, thereby simplifying the complexity of the setting of the splicing blocks 50. For example: the tiles 50 can be arranged on each splicing surface 10a in 3 rows and 3 columns, or 5 rows and 5 columns, and one of the tiles is vacant on a certain row on one splicing surface 10a to form an avoidance space, so that when the jigsaw puzzle is used, the tiles 50 adjacent to the avoidance space can slide into the avoidance space, and the sliding groove 10b is formed by matching two adjacent first bumps 200 with the splicing surface 10a, and the sliding groove 10b is formed without forming a groove on the splicing surface 10a, so that the forming complexity of the sliding groove 10b can be reduced, and the overall strength of the main body seat 10 can be improved by the connecting lugs of the first bumps 200.

Referring to fig. 4, fig. 5, fig. 6 and fig. 7, in an embodiment of the present invention, the first bump 200 includes a first fixing portion 210 and a first main body portion 230 connected to the first fixing portion 210; a first buckle 211 is arranged on one surface of the first fixing part 210 of the first bump 200 positioned on the splicing surface 10a, the main body frame 100 is provided with a first buckle hole 100a, and the first buckle 211 can be elastically clamped into or separated from the first buckle hole 100a, so that the first fixing part 210 of the first bump 200 positioned on the splicing surface 10a can be detachably connected to the main body seat 10;

the surface of the first fixing portion 210 of the first bump 200 at the edge, which is away from the first main body 230, is provided with a second buckle 213, the main body frame 100 is provided with a second buckle hole 100b, and the second buckle 213 can be elastically clamped into or separated from the second buckle hole 100b, so that the first fixing portion 210 of the first bump 200 at the edge can be detachably connected to the main body frame 100; or, the first fixing portion 210 of the first bump 200 at the edge is fixedly connected to the main body frame 100 on the side departing from the first main body portion 230; the side surfaces of the first fixing portions 210 of every two adjacent first protrusions 200, the surface of the first body portion 230 facing the first fixing portions 210, and the splicing surface 10a cooperate to form a sliding slot 10 b.

It can be understood that the first protrusion 200 on the splicing surface 10a is fastened and fixed to the first fastening hole 100a of the main body frame 100 through the first fastener 211 of the first fixing portion 210, so that the first protrusion 200 on the splicing surface 10a and the main body frame 100 can be separately and independently manufactured during the previous production, thereby facilitating the respective molding in the production process and improving the convenience of the production and manufacturing of the main body frame 100. When damage occurs at a later stage, the damaged first bump 200 can be removed for replacement, thereby avoiding local damage and the need for replacing the whole. The first buckle 211 and the first buckle hole 100a are fastened and fixed, so that the connection process of the main body frame 100 of the first bump 200 on the splicing surface 10a can be simplified, and the assembly and disassembly efficiency of the first bump 200 can be improved. Likewise, when the first protrusion 200 at the edge is fastened and fixed to the second fastening hole 100b of the body frame 100 by the second fastener 213 of the first fixing portion 210, the first protrusion 200 at the edge and the body frame 100 can be separately and independently manufactured during the previous production, thereby facilitating the respective molding during the production process to further improve the convenience of the production and manufacture of the body frame 100. When the first fixing portion 210 of the first bump 200 at the edge is fixedly connected to the main body frame 100 at a side away from the first main body 230, the first bump 200 at the edge and the main body frame 100 can be integrally formed, so that the connection strength of the first bump 200 and the main body frame at the connection position can be improved. The first fixing portion 210 and the first main body portion 230 of the first bump 200 disposed on the splicing surfaces 10a may be square, and the first fixing portion 210 and the first main body portion 230 of the first bump 200 disposed on the edge formed by two adjacent splicing surfaces 10a may be long and extend along the edge. Further, in order to improve the overall strength of the first bump 200, three adjacent first bumps 200 on three connected edges may extend to the vertex at the corner to form an integral body. In order to facilitate the sliding of the segment 50 between two different splicing surfaces 10a, the surface of the first main body 230 of the first protrusion 200, which is away from the first fixing portion 210, at the edge formed by two adjacent splicing surfaces 10a is disposed in an arc shape. In addition, it should be noted that the present application is not limited thereto, and in other embodiments, the first fixing portion 210 and the main body frame 100 may be fixed by magnetic attraction. Further, in order to improve the stability of the installation of the first protrusion 200 provided on the joint surface 10a, the joint surface 10a may be provided with a mounting groove 100c, and a groove bottom wall of the mounting groove 100c is formed with a fastening hole 100 a. The first fixing portion 210 of the first protrusion 200 is embedded in the mounting groove 100c at an end portion away from the first body portion 230, and abuts against a wall of the mounting groove 100 c. This can increase the contact area between the first bump 200 and the body frame 100, thereby improving the stability of the installation of the first bump 200.

In an embodiment of the present invention, the main body seat 10 further includes a plurality of second bumps 300, one second bump 300 is disposed at a corner formed by every adjacent three splicing surfaces 10a, and the second bump 300 and the first bump 200 adjacent to the second bump 300 and the splicing surfaces 10a cooperate to form the sliding slot 10 b.

It can be understood that, when the three adjacent first protrusions 200 located on the three connected edges can extend to the vertex of the corner to form a whole, the second protrusion 300 is disposed such that the main body frame 100 can also be formed with a sliding slot 10b at each corner (i.e. the vertex position formed by every three connected edges) for the sliding block 51 to receive and pass through, so that the splicing block 50 can be correspondingly disposed on each splicing surface 10a near the corner.
