Description

Technical Field

[0001] The utility model relates to the technical field of environmentally friendly floors, in particular to a spliced ​​low-formaldehyde environmentally friendly floor with a locking function. Background Art

[0002] Low-formaldehyde, environmentally friendly flooring refers to flooring whose formaldehyde emissions during use meet national environmental standards. This type of flooring can protect the health and safety of residents and typically utilizes harmless adhesives and coatings to minimize environmental pollution during production and use. Existing low-formaldehyde, environmentally friendly flooring typically lacks radial stop and lock features during installation. This makes it difficult to align the ends of two flooring pieces, reducing installation efficiency. Furthermore, the lack of a locking feature can cause already assembled flooring to misalign when other flooring is assembled, requiring rework. Utility Model Content

[0003] In order to overcome the above-mentioned deficiencies of the existing problems, the utility model provides a spliced ​​low-formaldehyde environmentally friendly floor with a locking function.

[0004] The technical solution adopted by the utility model to solve the technical problem is: a spliced ​​low-formaldehyde environmentally friendly floor with a locking function, which is glued with a wear-resistant layer, a decorative paper layer, a buffer layer, a base material layer and a moisture-proof layer in sequence using environmentally friendly glue from top to bottom, one side of the base material layer is fixedly connected to a card strip, and the other side of the base material layer is provided with a card slot used in conjunction with the card strip, and the card slot does not penetrate the base material layer, one side of the card strip is fixedly connected to a fan-shaped protrusion, the center point of the fan-shaped protrusion is located in the middle position of the card strip, and the side of the card strip fixedly connected to the fan-shaped protrusion is provided with a groove that matches the shape of the fan-shaped protrusion, and the bottom surface of the groove is aligned with the fan-shaped protrusion.
