[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] The utility model embodiment discloses a seamless splicing structure of a cork EVA composite sheet.

[0022] The utility model provides Figure 1-3 A seamless splicing structure of a cork EVA composite sheet is shown, comprising a hollow block 1, two fixing plates 2 and two first cork EVA composite sheets 3, the two fixing plates 2 are symmetrically fixedly arranged on both sides of the hollow block 1, the two first cork EVA composite sheets 3 are symmetrically arranged on both sides of the hollow block 1 and the ends close to each other are arranged on the surface of the corresponding fixing plates 2, the side wall of the hollow block 1 is symmetrically provided with a plurality of strip openings, each strip opening is slidably provided with an L-shaped card pin 4, each L-shaped card pin 4 is provided with a through hole, and each through hole is movably penetrated with a fixing rod 5, Each fixing rod 5 is fixedly arranged inside the hollow block 1, and one end of each L-shaped card pin 4 located outside the hollow block 1 is plugged into the corresponding first cork EVA composite sheet 3. A second cork EVA composite sheet 12 is fixedly arranged on the surface of the hollow block 1. By utilizing the clamping connection between the multiple L-shaped card pins 4 and the corresponding first cork EVA composite sheets 3, the connection between the two first cork EVA composite sheets 3 can be achieved. At the same time, the second cork EVA composite sheet 12 can be used to cover the connection after the connection, thereby avoiding the connection from being exposed, achieving an aesthetic effect.

[0023] like Figure 1-3 As shown, a screw rod 6 is rotatably arranged inside the hollow block 1, and a plurality of sliders 7 are threadedly sleeved on the rod wall of the screw rod 6. The side wall of each slider 7 is symmetrically fixedly connected with two L-shaped driving rods 8, and the other end of each L-shaped driving rod 8 is fixedly connected with a triangular block 9. The inclined surface of each triangular block 9 is in contact with and connected to the end of the corresponding L-shaped pin 4. By utilizing the set triangular block 9, the corresponding L-shaped driving rod 8 can drive the inclined surface of the corresponding triangular block 9 to squeeze the end of the corresponding L-shaped pin 4 during the movement of the slider 7, so that the tip of the L-shaped pin can be inserted into the corresponding first cork EVA composite sheet 3.

[0024] like Figure 1-2 As shown, a U-shaped rod 10 is fixedly arranged between two adjacent sliders 7. By using the multiple U-shaped rods 10, a fixed connection between two adjacent sliders 7 can be achieved, so that the multiple sliders 7 can be driven to move synchronously during the rotation of the screw rod 6.

One end of the two L-shaped limiting rods 11 are respectively slidably set inside the corresponding limiting grooves. By utilizing the sliding connection between the two L-shaped limiting rods 11 and the corresponding limiting grooves, the slider 7 can be limited to avoid driving the corresponding slider 7 to rotate during the rotation of the screw rod 6.

[0026] like Figure 1-2 As shown, one end of the screw rod 6 passes through the outside of the hollow block 1 and a driving groove (not shown in the figure) is opened on the end face. The opened driving groove can facilitate the driving of the screw rod 6, thereby driving multiple sliders 7 to rotate.

[0027] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
