Embodiment 1

[0032] The jigsaw puzzle structure designed in this embodiment is not much different from the existing jigsaw puzzle structure in appearance, as Figure 4 shown, fight figure 1 It is composed of multiple jigsaw puzzle pieces with Ω-shaped concave-convex structures on the sides. The jigsaw pieces are connected by an Ω-shaped concave-convex structure to limit their lateral spread. From its cross-sectional view, as Figure 5 shown, fight figure 1 The contact area 2 of two adjacent jigsaw puzzle pieces accounts for 75% of their corresponding contact side area, and the contact height h of the jigsaw puzzle pieces in the figure is 3 / 4 of the total height H; The side of the contact edge adopts arc chamfer transition. The contact area 2 between the jigsaw pieces is greatly increased, thereby increasing the bonding force connected between the jigsaw pieces. After the jigsaw puzzle is put together, it can be connected and fixed without fixing devices. The jigsaw puzzle piece is ...

Embodiment 2

[0036] Such as Figures 12 to 17 As shown, the basic structure of this embodiment is very similar to that of Embodiment 1, and the main improvement is that the frame 3 and the frame 3 are connected together. figure 1 A decorative strip 6 is arranged on the upper side of the concave-convex structure that cooperates with each other. to combine Figure 12 , 13 As shown, the decorative strip 6 is also dismantled into multiple pieces and respectively arranged on each frame piece. Also be provided with and fight as frame straight line piece 32 in its inner side figure 1 The upper side of the Ω-shaped groove 323 matched with the jigsaw pieces of the outer layer is provided with a decorative strip 6 . Frame corner block 31 inner side increase and fight figure 1 The omega-shaped groove 314 and the projection 313 matched by the puzzle piece of the outer layer are provided with a decorative strip 6 on both upper sides. After forming frame 3, form and spell on the inside of frame...

Abstract

The invention relates to a planar jigsaw puzzle which aims to overcome defects in the prior art and provide a plastic material planar jigsaw puzzle which has low processing difficulty, attractive appearance and safe use and can realize connection and fixation among jigsaw puzzle pieces. The planar jigsaw puzzle is formed by the mutual splicing of a plurality of plastic jigsaw puzzle pieces; mutually matched concave-convex connecting structures are arranged among the jigsaw puzzle pieces; the planar jigsaw puzzle has an improved structure that the edge in front of each plastic jigsaw puzzle piece is provided with a chamfer angle; the height of the chamfer angle is 5 percent to 50 percent of that of the contact surface of two adjacent plastic jigsaw puzzle pieces; and the contact area of two opposite and adjacent plastic jigsaw puzzle pieces is 95 percent to 50 percent of the corresponding contact side area of the two opposite and adjacent plastic jigsaw puzzle pieces. The design increases the contact area between the jigsaw puzzle pieces and improves the binding force between the jigsaw puzzle pieces. Because the contact area between the jigsaw puzzle pieces is greatly increased, a jigsaw puzzle can be connected and fixed without any fixing device after being spliced.

Description

technical field [0001] The invention relates to a plane jigsaw puzzle toy, more specifically a plane jigsaw puzzle made of plastic material with retro appearance, beautiful appearance and self-fixation. technical background [0002] A plane jigsaw puzzle is a toy composed of multiple pieces of jigsaw puzzle pieces with concavo-convex structures that cooperate and connect with each other. Existing jigsaw puzzles are composed of paper jigsaw pieces. Due to the characteristics of the material and the processing technology, the contact area between the jigsaw pieces is not large enough to form a firm fixing force. Therefore, existing jigsaw puzzles must be fixed in the plane frame by means of a plane frame, so as to realize the fixing of the picture. On the one hand, the cost of the toy is increased, and it is inconvenient to carry; on the other hand, the color and shape of the separately purchased fixed frame are difficult to match with the color and pattern of the puzzle, whi...
