Description

Dampproofing timber

Technical Field

The invention belongs to the technical field of wooden doors, and particularly relates to a moisture-proof wooden door.

Background

The wooden door is made up by using natural raw wood obtained from forest as door core, drying treatment, blanking, planing, making tenon, drilling hole and high-speed milling to form the invented product. The wooden door can adapt to various different architectural styles and has a large appearance, so the wooden door is applied to a great extent in civil, commercial buildings or houses. However, the traditional wooden door is formed by processing pure wood, and the wood is extremely easy to expand after being wetted, so that the wooden door is not matched with the door opening, and the door is difficult to close. The wooden door is usually painted to prevent the wooden door from being affected with damp in the prior art, but the damp-proof effect is still poor, and the wooden door is still easy to be affected with damp and expand after being used for a long time.

Disclosure of Invention

The invention provides a damp-proof wooden door which is not easy to damp and expand in order to overcome the defects of the prior art.

In order to achieve the purpose, the invention adopts the following technical scheme: a moisture-proof wooden door comprises

A door panel;

the pulling assemblies are used for obliquely pulling every two end angles of the door panel; the door comprises four L-shaped positioning plates respectively matched with four end corners of a door panel, a first pulling assembly for realizing the connection between the first diagonal side positioning plates and a second pulling assembly for realizing the connection between the second diagonal side positioning plates;

the positioning support structure comprises a first stabilizing part matched with the first pulling assembly and a second stabilizing part matched with the second pulling assembly;
