Description

Technical Field

[0001] The utility model relates to a floor, in particular to a round hole co-extruded floor with a flame retardant function, belonging to the technical field of round hole co-extruded floors. Background Art

[0002] Round hole co-extrusion flooring is a new type of flooring material, which is made by co-extrusion process. This flooring combines the advantages of multiple materials, usually including wood plastic composite materials and plastics. The co-extrusion process refers to the extrusion of different materials through the same extruder head to form a multi-layer structure in order to achieve the purpose of optimizing the performance of the floor.

[0003] A flame retardant and non-slip co-extruded wood-plastic floor is disclosed in the Chinese patent application publication specification CN203924592U. The baseboard shell adopts a flame retardant shell, the core is an ordinary wood-plastic profile, and the shell is prepared by plastic, wood powder, environmentally friendly flame retardant and other wood-plastic additives, which effectively improves the flame retardant properties of the co-extruded product and makes up for the shortcomings of ordinary plastic-wood composite materials.

[0004] In actual applications, it is found that the flame retardant and non-slip co-extruded wood-plastic floor can delay the spread of flames and reduce the burning speed through the flame retardant layer. The floor has no thermal insulation protection inside, and it is difficult to prevent the conduction of heat. High temperature will still be conducted to the core made of ordinary wood-plastic profiles, which may cause damage to the core. When installing the round hole co-extruded floor, the installer needs to first align the stainless steel clip with the keel, then hammer the clip to snap it into the side of the bottom plate, and finally fix the clip with screws. The installation is relatively complicated. For this reason, we provide a round hole co-extruded floor with flame retardant function. Utility Model Content

[0029] Please refer to Figure 2 and Figure 4A sliding assembly 2 is provided in the slot 102 on the right side of the core 101, and the sliding assembly 2 includes a moving shell 201 slidably connected to the slot 102, and the moving shell 201 can slide in the slot 102, and the inner wall of the moving shell 201 is provided with a first compression spring 202, and both ends of the first compression spring 202 are fixed with a slide plate 203, and the side of the two slide plates 203 away from each other is fixed with a slide post 204 that is in sliding contact with the moving shell 201, and the elastic force generated by the deformation of the first compression spring 202 can move the two slide plates 203 and the two slide posts 204 away from each other, and then the two slide posts 204 are pressed against the slot 102 opened on the side of the core 101, and the moving shell 201 can be limited by the coordinated arrangement of the first compression spring 202, the slide plate 203 and the slide post 204, so that the moving shell 201 will not slide easily, thereby improving the stability of the moving shell 201.

[0030] A guide block 205 is fixed on the side of the movable shell 201. By setting the guide block 205, the movable shell 201 can be limited to prevent the guide block 205 from sliding out of the slot 102. The slot 102 slidably connected to the movable shell 201 is provided with a guide groove 206 that is in sliding contact with the guide block 205. The movable shell 201 in the slot 102 will also drive the installation shell 301 to move, thereby facilitating the guide block 205 provided on the installation shell 301 to be aligned with the installation frame, and then fastened with screws.

[0031] Please refer to Figure 2 , Figure 3 and Figure 4 A mounting mechanism 3 for installation is provided on the sliding assembly 2 and the card slot 102, and the mounting mechanism 3 includes a mounting shell 301 fixed to a side of the movable shell 201, a second compression spring 302 is fixed to the inner wall of the mounting shell 301, and a trapezoidal block 303 that is in sliding contact with the inner wall of the mounting shell 301 is fixed to the top surface of the second compression spring 302.

[0032] When the trapezoidal block 303 is squeezed, the inclined surface of the trapezoidal block 303 is stressed, which will cause the trapezoidal block 303 to move in the direction close to the second compression spring 302. The second compression spring 302 will be deformed under the squeezing of the trapezoidal block 303. When the trapezoidal block 303 moves to the limiting groove 304, under the action of the elastic force generated by the deformation of the second compression spring 302, the trapezoidal block 303 will move to the inside of the limiting groove 304, and then the mounting shell 301 is limited by the matching setting of the trapezoidal block 303 and the limiting groove 304. The length of the mounting shell 301 is greater than the length of the slot 102, that is, after the mounting shell 301 is inserted into the slot 102, the mounting hole 305 is on the outside of the slot 102, so as to avoid the screws installed in the mounting hole 305 from affecting the matching between the trapezoidal block 303 and the limiting groove 304.

[0034] Working principle: When in use, first align the installation shell 301 of the floor with the card slot 102 of another floor, then move the entire floor close to the other floor, the trapezoidal block 303 will move into the card slot 102, when the trapezoidal block 303 is squeezed, the inclined surface of the trapezoidal block 303 is stressed, which will make the trapezoidal block 303 move in the direction close to the second compression spring 302, when the trapezoidal block 303 moves to the limit groove 304, under the elastic force generated by the deformation of the second compression spring 302, the trapezoidal block 303 will move to The inside of the limiting groove 304 and the matching setting of the trapezoidal block 303 and the limiting groove 304 complete the limitation of the mounting shell 301, and the mounting shell 301 is fixed to the mounting frame through the mounting hole 305 and the screws, so as to further improve the fixing effect between the floors.
