Abstract

Wood floor assembled by metal lock is composed of strip wood floor blocks (6,7) and metal locks (1). Both sides of the wood floor blocks (6,7) have lapped tenons mating with each other, and both end surfaces have mating tongues (13) and grooves (14) respectively. The metal lock (1) is assembled on one side of the wood floor lower flat surface, and the metal lock (1) is composed of a bottom plate (16) and four vertical walls (17,18,21). The bottom plate (16) is a rectangle flat plate, and two flat plate vertical walls (17) and two vertical walls (18,21) with trapezoid cross-section are set on the bottom plate (16). Tongues and grooves are adopted at both ends of the floor, such that the junctions at the ends of the floor will not be low-lying by the stress. And the problems to be solved are making the floor more flat during assembling, and making assembling operation simple, easy and reliable.

Description

Manual metal lock solid wood flooring

Technical field

[1] The invention belongs to the field of wooden flooring, and in particular to wooden flooring with metal buckles.

Background technique

[2] The wooden floor in the traditional room is assembled from a single piece of wooden floor strip. Single wooden floor strips are made to standard

, the monolithic wooden floor strips are assembled to each other and become the entire floor. The bottom plate is assembled in a variety of different ways. A floor with a metal lock is one of the fits. In the prior art, the metal buckle has a fixed connection to one side of the metal strip, and the other end of the metal lock is suspended. The suspended end and the side of the floor are connected to the other floor. The two vertical walls of the buckle are provided with elastic glue sticks, and the elastic force of the elastic glue sticks is used to fix the floors. The disadvantages of the prior art are: the elastic glue sticks on the two vertical walls of the metal buckle, one of the glue sticks is arranged on the side of the vertical wall, and the side of the floor is in contact with the glue stick, and the glue stick is greatly deformed under pressure. The reaction force directly becomes the force to push the floor open, which often causes the single quick floor to be pressed unevenly during the installation process, and can only be flattened after installing several floors, so that its reliability is affected.
