As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0021] like Figure 1-4As shown, a leg support foam fixing structure includes a leg support structure 1, embedded clamping plates 2 are embedded on the four corners of the bottom surface of the leg support structure, and a connecting component 3 is detachably connected to the embedded clamping plate. The connecting component includes three connecting platforms 4 arranged from top to bottom, and the middle parts of adjacent connecting platforms are connected by connecting columns 5. The middle connecting platform is clamped on the embedded clamping plate, and a claw component is installed on the top of the upper connecting platform. The leg support structure is clamped on the leg support frame through the claw assembly. The detachable connection between the embedded clamping plate and the connecting component makes the connecting component replaceable, which reduces the possibility of the whole being directly scrapped due to damage of the connecting component, and is easy to use.

[0022] In this embodiment, the embedded pallet includes an upper pallet 6 and a lower pallet 7 corresponding to each other. The left and right sides of the upper pallet and the lower pallet are connected by a side plate 8. A slide groove 9 for the middle connecting platform to slide is formed between the upper pallet and the lower pallet. A slide hole 10 is set in the middle part of the same end of the upper pallet and the lower pallet along the sliding direction of the middle connecting platform. The slide hole is connected to the slide groove, and the connecting column is slid into the corresponding slide hole. When in use, the middle connecting platform slides into the slide groove, and the upper and lower connections of the middle connecting platform are respectively slid into the corresponding slide holes, so as to realize the detachable connection between the embedded pallet and the connecting component.

[0023] In this embodiment, for the sake of reasonable design, one side of the sliding hole of the embedded clamping plate faces the outside of the leg support structure.

[0024] In this embodiment, the height of the connecting column between the upper and middle connecting platforms is no greater than the thickness of the upper card board, which enhances the fixing strength. At least one protrusion is provided on the table surface of the middle connecting platform close to the upper connecting platform, which can make the connecting platform more compact and stable when embedded in the card board. The height of the connecting column between the lower and middle connecting platforms is greater than the height of the connecting column between the upper and middle connecting platforms, which enhances the stability between the connecting component and the embedded card board.

[0025] In this embodiment, a vertical extended fixing column 11 is provided on the top middle part of the upper connecting platform, and the depth of the embedded card plate is increased by extending the fixing column, and the thickness of the combined cotton and the card plate is reserved. The claw assembly is installed on the extended fixing column, and the claw assembly includes at least two claws 12. The claws are installed obliquely on the end of the extended fixing column in the shape of an umbrella rib, and the other end of the claw faces the outside of the upper connecting platform.

[0026] In this embodiment, the leg support structure is a foam structure formed by foaming. When in use, firstly, four embedded clips are placed in the foaming mold at a position relative to the fixed point of the embedding port. Then, after the leg support structure is foamed and formed in the foaming mold, the four embedded clips are wrapped in cotton. Then, the connecting components are installed, so that the leg support structure is clamped on the leg support frame through the clamping claws.
