DETAILED DESCRIPTION

[0019] In order to make the technical means, creation features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0020] As shown in Figure 1 - Figure 4 A kind of anti-delamination shoe insole paperboard, including insole 1, shoe insole paperboard body 2 and outsole 3, shoe insole paperboard body 2 is arranged between upper insole 1 and lower outsole 3, shoe insole paperboard body 2 is embedded between insole 1 and outsole 3 by top embedding strip 8 of top surface and bottom embedding strip 9 of bottom surface, and also fixedly connected between insole 1 and outsole 3 by first adhesive layer 10 of top surface and second adhesive layer 11 of bottom surface.

[0021] As shown in Figure 2 The bottom surface of insole 1 is provided with a plurality of bottom embedding grooves 4, and bottom embedding groove 4 presents arch shape, and the arch-shaped bottom embedding groove 4 arranged on insole 1 is used for matching the embedding connection of shoe insole paperboard body 2, and the top surface of insole 1 is also fixedly installed with first waterproof layer 5, which can prevent moisture inside the shoe from entering shoe insole paperboard body 2 by setting first waterproof layer 5;

[0022] As shown in Figure 3 The bottom surface of outsole 3 is provided with a plurality of top embedding grooves 6 corresponding to bottom embedding groove 4, and top embedding groove 6 also presents arch shape, and the arch-shaped bottom embedding groove 4 arranged on outsole 3 is used for matching the embedding connection of shoe insole paperboard body 2, and the bottom surface of outsole 3 is also fixedly installed with second waterproof layer 7, which can prevent external moisture of the shoe from entering shoe insole paperboard body 2 by setting second waterproof layer 7;

[0023] As shown in Figure 1 - Figure 3As shown, the first waterproof layer 5 and the second waterproof layer 7 are both made of polyurethane material, and the first waterproof layer 5 and the second waterproof layer 7 made of polyurethane material can improve the moisture resistance and waterproof performance of the shoe midsole paperboard body 2, and prevent water vapor or moisture from entering the shoe midsole paperboard body 2;

[0024] As shown in the drawings, Figure 4 As shown, the top surface and the bottom surface of the shoe midsole paperboard body 2 are respectively fixedly installed with top surface embedding strips 8 and bottom surface embedding strips 9 in an arched shape, and the top surface embedding strips 8 and the bottom surface embedding strips 9 correspond to the bottom surface embedding grooves 4 and the top surface embedding grooves 6 and are respectively embedded and fixedly installed in the bottom surface embedding grooves 4 and the top surface embedding grooves 6 in a press-fit manner. The top surface embedding strips 8, the bottom surface embedding strips 9 and the shoe midsole paperboard body 2 are of an integrated structure. After the bottom surface embedding strips 9 of the bottom surface of the shoe midsole paperboard body 2 are press-fitted into the top surface embedding grooves 6 on the top surface of the outsole 3, the top surface embedding strips 8 of the top surface of the shoe midsole paperboard body 2 are then press-fitted into the bottom surface embedding grooves 4 on the bottom surface of the insole 1. This can improve the connection friction between the insole 1, the shoe midsole paperboard body 2 and the outsole 3. The arrangement of the top surface embedding strips 8 and the bottom surface embedding strips 9 can play the role of rib stiffeners, preventing the shoe from breaking after being subjected to bending force.
