Abstract
Description
Technical Field
[0001] This utility model relates to the field of multi-layer wood flooring technology, and in particular to a multi-layer wood flooring with good wear resistance. Background Technology
[0002] Multi-layer wood flooring uses cross-laminated plywood as its base material and selects high-quality precious wood as its surface layer. After being coated with resin adhesive, it is manufactured under high temperature and pressure in a hot press. It is not easily deformed or cracked, has minimal shrinkage and expansion, and possesses good ability to regulate indoor temperature and humidity. The surface layer displays the natural wood grain, installation is simple, and it has a wide range of applications. Its price is higher than composite flooring but lower than solid wood flooring. It is suitable for installation in rooms with underfloor heating.
[0003] Existing technologies, such as the utility model with publication number CN221219504U, relate to the field of flooring technology and disclose a multi-layer wood flooring with good wear resistance. This utility model includes a decorative surface layer, a wear-resistant layer on top of the decorative surface layer, a frame at the bottom of the decorative surface layer, and a flame-retardant layer fixedly connected to the inner wall of the frame at the bottom of the decorative surface layer. This wear-resistant multi-layer wood flooring allows for easy splicing by inserting the first splicing board from the left multi-layer wood flooring into the first connecting groove of the right multi-layer wood flooring until the two multi-layer wood floorings are in contact. Then, the left or right multi-layer wood flooring can be slowly moved back and forth to complete the splicing. Similarly, the second splicing board from the front multi-layer wood flooring can be inserted into the second connecting groove of the rear multi-layer wood flooring, and then the front or rear multi-layer wood flooring can be slowly moved left and right to complete the splicing. This achieves the goal of easy splicing and solves the problem that most existing wear-resistant multi-layer wood flooring installations are cumbersome and inconvenient to splice.
[0004] In our daily work, we have found that existing multi-layer wood flooring is equipped with a wear layer. Traditional wear layers are often tightly integrated with other structures of the flooring. If the wear layer needs to be replaced, not only does it require the removal of the entire floor, but the operation process is also extremely complicated and incurs high economic costs, resulting in a waste of time and manpower and causing overall inconvenience in use.

A spring is sleeved on the surface of the positioning rod, and the two ends of the spring are fixedly connected to the positioning rod and the inner wall of the insert sleeve, respectively. With the above components, when the insert is inserted and connected to the insert sleeve, the insert can push the positioning rod, and the positioning rod can be inserted into the inner wall of the multi-layer wood flooring, thereby realizing the installation positioning.
[0008] Preferably, the positioning rod consists of a rod body and a ball head, with the ball head fixed to one end of the rod body. After the insert is connected to the sleeve via the aforementioned components, the insert can push the ball head, which in turn drives the rod body to insert into the inner wall of the multi-layer wood flooring.

The wear-resistant layer can be quickly disassembled and assembled through the structure of the sleeve, positioning part, cover plate and insert. When the wear-resistant layer is damaged, the insert can be easily removed by rotating the cover plate with the help of a suction cup tool, and then the wear-resistant layer can be quickly removed and replaced, which greatly reduces the maintenance cost and improves the overall practicality.
[0015] In this invention, the wear-resistant layer includes a decorative layer and a polyurethane coating. The thickness of the polyurethane coating is controlled at 0.3-0.5mm, which ensures good wear resistance and can effectively resist wear caused by furniture movement, shoe sole friction, etc. Attached Figure Description

[0023] Please see Figures 1-5This utility model provides a technical solution: a multi-layer wood floor with good wear resistance, comprising a multi-layer wood floor body 1, the multi-layer wood floor body 1 including a bottom layer, a substrate layer and a surface layer, an auxiliary device 2 provided on the multi-layer wood floor body 1, the auxiliary device 2 including a wear-resistant layer 21 located above the multi-layer wood floor body 1, the wear-resistant layer 21 including a decorative layer 211 and a polyurethane coating 212, the polyurethane coating 212 being fixed on the decorative layer 211, the polyurethane coating 212 having a thickness of 0.3-0.5mm, an installation part provided between the wear-resistant layer 21 and the multi-layer wood floor body 1, the installation part including a sleeve 25 fixed on the surface of the wear-resistant layer 21, the surface of the multi-layer wood floor body 1 having an insertion hole 27 for the sleeve 25, the inside of the sleeve 25 being provided with multiple sets of positioning parts 24, the positioning parts 24 being inserted into the inner wall of the multi-layer wood floor body 1, the inner wall of the sleeve 25 being threadedly connected to an insert 23, the upper end of the insert 23 being fixedly connected to a cover plate 22.
[0024] In this implementation plan, the wear resistance of the multi-layer wood flooring 1 can be improved by the wear-resistant layer 21. When the wear-resistant layer 21 is damaged, it can be quickly disassembled and replaced according to the installation part. First, the cover plate 22 and the insert 23 are rotated by the suction cup tool, and the insert 23 is taken out. The insert 23 loses its pressure on the positioning part 24, and the positioning part 24 is moved out from the inner wall of the multi-layer wood flooring 1, so that it can be quickly replaced.
[0025] Specifically, the positioning part 24 includes a positioning rod 241 that is slidably connected to the inner wall of the sleeve 25. A spring 242 is sleeved on the surface of the positioning rod 241, and the two ends of the spring 242 are fixedly connected to the positioning rod 241 and the inner wall of the sleeve 25, respectively.
[0026] In this implementation scheme: the positioning rod 241 is connected to the rod body and the ball head. The ball head is fixed to one end of the rod body. When in use, after the insert 23 is inserted and connected to the sleeve 25, the insert 23 can push the ball head, and the ball head drives the rod body to insert into the inner wall of the multi-layer wood flooring 1, thereby realizing the installation positioning.
[0027] Specifically, the insert 23 includes a rod 232 and a threaded end 231. The threaded end 231 is fixed on the surface of the rod 232. The diameter of the threaded end 231 is larger than the diameter of the rod 232. The insertion end of the rod 232 is pointed.
[0028] Specifically, multiple auxiliary rods 26 are fixedly connected to the surface of the wear-resistant layer 21, and multiple insertion holes 28 for inserting the auxiliary rods 26 are opened on the surface of the multi-layer wood flooring 1.
[0029] In this implementation scheme, multiple auxiliary rods 26 are inserted into the second socket 28 to further improve the overall stability.
[0030] Working principle: In use, the wear-resistant layer 21 is first placed on the multi-layer wood flooring 1. The wear resistance is improved by the decorative layer 211 and the polyurethane coating 212. Then, the auxiliary rod 26 is inserted into the second insertion hole 28, and the insertion sleeve 25 is inserted into the first insertion hole 27. Then, the insert 23 is inserted into the insertion sleeve 25. The pointed insertion rod 232 in the insert 23 will contact the ball head in the positioning rod 241, and the positioning rod 241 will move. The spring 242 will be stressed, and then the insertion rod 23 will be inserted into the first insertion hole 27. The threaded end 231 on the insert 2 is threadedly connected to the insert sleeve 25. The insert rod 232 can drive multiple positioning rods 241 to be inserted into the inner wall of the multi-layer wood flooring 1 to complete the assembly. When replacing, simply use a suction cup tool to hold the cover plate 22 and drive the cover plate 22 to rotate, so that the threaded end 231 loses its threaded connection with the insert sleeve 25. The entire insert 23 can be taken out, and the spring 242 drives the positioning rods 241 to reset and pull them out from the inner wall of the multi-layer wood flooring 1. The wear layer 21 can then be removed to complete the replacement operation.
