Abstract
Description
Technical Field
[0001] The utility model relates to the field of building decoration, in particular to an ultra-thin PVC block buckle floor. Background Art
[0002] Flooring is a widely used home decoration material and is widely adopted by people. At present, the real estate market in society is saturated, and more and more old houses need to be renovated. Renovating the floor of an old house is a headache. In the past, the original floor, such as tiles, was knocked off and re-laid, which was a time-consuming and labor-intensive project. How to choose floor paving materials that can be renovated quickly has attracted more and more attention.
[0003] There are two main types of PVC block floors suitable for quick renovation. One is the non-buckled PVC block thin floor, which is mainly laid and glued. The advantages are light weight, low transportation cost and manufacturing cost. The disadvantage is that the floor is thin and it is difficult to set floor buckles of sufficient strength. During use, a large amount of glue is needed for adhesion, and a large amount of glue is easy to pollute the indoor gas environment and affect the human body. In addition, when the floor is affected by thermal expansion and contraction, it is easy to produce shrinkage joints, which affects the aesthetics of the floor. The other is the thick buckle floor. The thinnest buckle floor known so far is 3.0mm thick. In order to achieve a more stable splicing effect, the floor needs to have a three-layer structure. The advantage of this type of floor is that the buckle splicing will not produce shrinkage joints during use. The disadvantage is that the thickness is large, the weight is large, and the transportation cost and manufacturing cost are relatively high.
[0004] Therefore, the present invention combines the advantages of both to design a new type of ultra-thin PVC block buckle floor. Designing a new buckle buckle type on the thin floor can not only solve the problem that the thin floor is prone to shrinkage joints, but also solve the problem that the thick floor is high in cost and thickness.

DETAILED DESCRIPTION
[0029] In order to make the purpose, technical scheme and advantages of the implementation of the utility model clearer, the specific implementation methods of the utility model are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the utility model, but not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0031] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0032] like Figure 1 As shown, the ultra-thin PVC block buckle floor designed by the utility model has a four-layer structure, which is UV layer 1, wear-resistant layer 2, decorative film layer 4 and substrate layer 3 from top to bottom. The buckle type of traditional floor is usually a three-layer structure, but it is inconvenient to open a three-layer buckle type in ultra-thin floor, and the processing is difficult. In addition, the strength of the thin three-layer structure is very low, and it is easy to break during transportation or splicing. For this reason, the application designs a buckle suitable for 1.5mm~2.0mm ultra-thin PVC block floor, as shown in the following figure. Figure 2 and Figure 3As shown. The buckle includes a male groove and a female groove, wherein the male groove includes a first protrusion 5 located on the base material layer 3, and the first protrusion 5 has a lower groove 6 that is concave in the opposite direction of the first protrusion 5 on the side close to the bottom of the floor, and a first inclined surface 7 is provided on the vertical surface of the first protrusion 5 close to the top of the floor; the female groove includes a recessed portion 8 located on the base material layer 3, and the recessed portion 8 has a second protrusion 10 that is protruding in the opposite direction of the recessed portion 8 on the side close to the bottom of the floor, and a second inclined surface 9 is provided on the vertical surface of the recessed portion 8 close to the top of the floor. Both the first inclined surface 7 and the second inclined surface 9 at least pass through the UV layer 1 and part of the wear-resistant layer 2. When the male groove is spliced with the female groove, the first inclined surface 7 and the second inclined surface 9 are symmetrically distributed along the vertical line passing through the contact point at the bottom of the inclined surface, forming an obtuse angle with a smooth transition and an opening upward. This type of buckle type has only two layers as a whole. When in use, you only need to splice the male groove and female groove of the two floors so that the male groove lock tongue and the female groove can produce the function of locking up and down, and then apply a small amount of glue locally to fix the buckle floor to the ground.
[0033] The overall thickness of the ultra-thin PVC block snap-on floor is only 1.5mm~2.0mm, of which the wear-resistant layer 2 is 0.1mm~0.3mm thick, the substrate layer is 1.2mm~1.5mm thick, the height of the first protrusion 5 and the recessed portion 8 in the male and female grooves is 0.4mm~0.5mm, of which the recessed portion 8 is slightly larger than the first protrusion 5, and the height of the second protrusion 10 and the lower slot 6 is 0.55mm~0.75mm.
[0034] In some specific embodiments, when the thickness of the floor is 1.8 mm to 2.0 mm, the thickness of the wear-resistant layer 2 is 0.2 to 0.3 mm. At this time, the first inclined plane 7 and the second inclined plane 9 only pass through the UV layer 1 and part of the wear-resistant layer 2. The angles between the first inclined plane 7 and the second inclined plane 9 and the horizontal plane are both 20°, and an angle of 140° is formed between the two inclined planes. The splicing schematic diagram is as follows: Figure 4 Specifically, when the thickness of the buckle floor is 2.0 mm, the thickness of the wear-resistant layer 2 is 0.3 mm, the height of the first inclined surface 7 and the second inclined surface 9 is 0.2 mm, the height of the first protrusion 5 and the recessed portion 8 is 0.5 mm, and the height of the second protrusion 10 and the lower groove 6 is 0.75 mm.
[0035] In some specific embodiments, when the thickness of the floor is 1.5 mm to 1.7 mm, the thickness of the wear-resistant layer 2 is 0.1 to 0.2 mm. At this time, the wear-resistant layer 2 is relatively thin, so the first inclined plane 7 and the second inclined plane 9 pass through the UV layer 1, the wear-resistant layer 2 and part of the base material layer 3. The angles between the first inclined plane 7 and the second inclined plane 9 and the horizontal plane are both 24.5°, and an angle of 131° is formed between the two inclined planes. The splicing schematic diagram is specifically shown as follows: Figure 5Specifically, when the thickness of the buckle floor is 1.5 mm, the thickness of the wear-resistant layer 2 is 0.1 mm, the height of the first inclined surface 7 and the second inclined surface 9 is 0.3 mm, the height of the first protrusion 5 and the recessed portion 8 is 0.5 mm, and the height of the second protrusion 10 and the lower groove 6 is 0.55 mm.
[0036] In some specific embodiments, in order to facilitate the tightening of the floor when laying the snap-on floor, the second protrusion 10 is set to be shorter than the depth of the lower groove 6. When the male groove and the female groove are spliced, there is a gap between the second protrusion 10 and the lower groove 6, which is also conducive to the squeezing out of excess glue.
[0037] In some specific embodiments, in order to ensure that users have a good visual experience and walking feel, the surface of the UV layer 1 of the snap-on floor is set to an anti-slip surface, the first bevel 7 and the second bevel 9 are set to a rough surface, and embossing is used to imitate the surface texture of wood or stone. The rough bevel is also conducive to the beautification of the floor seams.
[0038] In some specific embodiments, in order to prevent the edge of the buckle floor from scratching human skin during transportation and use, a first chamfer 11 is provided at the bottom of the lower slot 6 and a second chamfer 12 is provided at the bottom of the second protrusion 10 .
[0039] The embodiments of the present invention are described in detail above, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
