Description

Technical Field

[0001] The utility model belongs to the technical field of boards, in particular to a moisture-proof formaldehyde-free veneer plywood. Background Art

[0002] Formaldehyde-free veneer plywood is plywood bonded with formaldehyde-free glue. Formaldehyde-free veneer plywood is widely used in home interior decoration, construction and other fields. It combines the natural beauty of wood with the environmental performance of formaldehyde-free glue, providing a high-quality, environmentally friendly and decorative material choice.

[0003] Existing plywood is usually glued together into a whole using formaldehyde-free glue. Because it simply uses the boards to bond together, it is easily affected by moisture after being installed on the ground, which in turn affects the service life of the plywood. In addition, traditional plywood uses screws to fix multiple plywood sheets during installation, and the installation process is cumbersome. Therefore, we propose a moisture-proof formaldehyde-free and veneerable plywood. Utility Model Content

[0004] The purpose of the utility model is to provide a moisture-proof formaldehyde-free veneer plywood.

[0007] Furthermore, the through hole is provided inside the outer plate, but the through hole does not penetrate the inner and outer walls of the outer plate.

[0008] Furthermore, a limiting block is fixedly connected to the outer wall of the outer sleeve, and the limiting blocks are symmetrically distributed with the outer sleeve as the axis. A convex plate is fixedly connected to the side of the outer sleeve away from the limiting block.

[0009] Furthermore, the convex plate can be completely matched with the limiting block, and a plurality of rivets are rotatably connected to the outer wall of the outer sleeve plate, and the rivets extend from the outer wall of the outer sleeve plate to the outer wall of the back plate.

[0010] Furthermore, the dehumidification mechanism includes a through pipe, the through pipe is made of steel, and a plurality of air holes are opened on the outer surface of the through pipe.

[0011] Furthermore, a fixing seat is fixedly connected to the inner wall of the bottom of the through pipe, and the fixing seats are symmetrically distributed with the through pipe as the axis. The inner wall of the fixing seat is provided with an internal thread.

[0012] Furthermore, a screw is threadedly connected on the outer surface of the internal thread, and the screw can be rotated inside the fixing seat and tightened into the outer wall of the back plate.

[0013] The utility model has the following beneficial effects:

[0014] 1.
