Description

Technical Field

[0001] The utility model belongs to the technical field of solid wood composite boards, and in particular relates to an anti-cracking solid wood composite board. Background Art

[0002] Solid wood composite boards are divided into multi-layer solid wood composite boards and three-layer solid wood composite boards. Traditional solid wood floors are made of a whole piece of wood. Solid wood composite boards divide the floor into multiple wood layers. The wood in these multiple wood layers is different. The surface layer is mostly the wood of the name of the wood sold, and the bottom is mostly made of other high-hardness wood. For example, pine and willow wood are suitable for floor heating. Solid wood composite boards are multi-layered, so they alleviate the expansion force of geothermal heat on wood, which is equivalent to a buffering effect.

[0003] Existing solid wood composite panels have the following defects during assembly and laying:

[0004] (1) When existing solid wood composite panels are laid and assembled, there is a certain gap between the panels, and the solid wood composite panels are prone to movement, making their assembly unstable and causing the gap between adjacent solid wood composite panels to become larger. For this reason, we propose a crack-resistant solid wood composite panel. Utility Model Content

[0012] Preferably, a mesh structure is laid inside the composite board body, and the mesh structure is made by weaving transverse nylon ropes and longitudinal nylon ropes.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) Through the designed fixing block, pin groove, pin block and assembly groove, pin blocks and pin grooves are respectively arranged on the surface of the composite plate body. When assembling the composite plate body, the pin block on one side of the composite plate body is inserted into the pin groove of the adjacent plate body. During the insertion process, the end face of the pin block and the fixing block squeeze each other, pushing the fixing block to move up to avoid. After the pin block is completely inserted into the pin groove, the fixing block moves down and is inserted into the fixing groove, so as to fix the adjacent composite plates to each other, avoid the movement of the plate body assembly and cause the plate body gap to be too large, so that the assembly of the utility model is more firm. Through the designed anti-slip block and anti-slip groove, the fixing block is limited to avoid the fixing block from escaping from the assembly groove. Through the designed spring, an elastic squeezing effect is applied to the fixing block to ensure that the fixing block does not move down under the action of gravity and is not inserted into the fixing groove. Through the designed support tube and support column, the spring is supported and corrected to avoid the spring from being squeezed and bent excessively and losing its elasticity. Through the designed ball bearing, a lubrication effect is played to reduce the friction resistance between the fixing block and the pin block.
