Technical field

The invention relates to the technical field of carpet installation, in particular to a carpet metal sticker and a carpet fixing structure for fixing carpets.

Background technique

PVC carpets are carpets produced using polyvinyl chloride resin materials. Specifically, polyvinyl chloride and its copolymer resins are used as the main raw materials, and fillers, plasticizers, stabilizers, colorants and other auxiliary materials are added to form a continuous substrate. It is made by uniform mixing, coating process or calendering and extrusion process, which can replace pure wool carpet and chemical fiber carpet. PVC carpet has the characteristics of soft texture, bright colors, comfortable and durable, easy to clean, non-flammable, self-extinguishing, and not afraid of moisture, so it is especially suitable for hotels, shopping malls, stages, residences and other places. Because of its good water resistance and slip resistance, it can effectively prevent the carpet from shifting, so it is also particularly suitable for use in the bathroom. PVC carpet is very unique because of its development and production process. After meeting the needs of practicality, it emphasizes the taste of the latest fashion and popular decoration.

Therefore, PVC carpets are laid in more and more environments. At present, PVC carpets are glued to the ground. But it is well known that when installing a PVC carpet on the floor, you will first sprinkle some glue. The glue will not cover the entire floor, but a small amount of glue will be sprayed at intervals. Therefore, when the carpet is attached to the floor , After using for a long time, the phenomenon of warping angle and displacement will occur, which will affect the use of the carpet.

Summary of the invention

In view of this, the present invention provides a carpet metal sticker and a carpet fixing structure for fixing carpets that can prevent the phenomenon of curling, so as to solve the above-mentioned problems.

A carpet metal sticker for fixing carpets includes a base plate, four hanging carpet areas arranged on one side of the base plate, and an adhesive layer arranged on the other side of the base plate. The four hanging carpet areas intersect at a central point. The substrate includes a central axis passing through the center point and perpendicular to the plane where the substrate is located. Each of the hanging carpet areas includes a plurality of hanging needle teeth made of metal material extending from the base plate. The angle between the extension direction of the hooking needle teeth and the central axis is an acute angle, and the acute angle is between 70 degrees and 80 degrees. Each hooking needle tooth includes a tooth tip. The hooking needle teeth and the hooking needle teeth on each buckle carpet area are spaced apart and arranged equidistantly. The hooking needle teeth and the hooking needle teeth on the two adjacent hooking carpet areas are equally spaced.

Detailed ways

Specific embodiments of the present invention will be described in further detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

As shown in Figures 1 to 3, which are schematic structural diagrams of the carpet fixing structure provided by the present invention. The carpet fixing structure is used to fix at least one carpet 10, that is, at least one carpet metal sticker 20 for fixing the carpet is used to fix the carpet 10. In this embodiment, in order to better illustrate the structure and working principle of the carpet fixing structure, the carpet fixing structure fixes four carpets 10. The carpet may be a PVC carpet. As is well known, all types of carpets, such as PVC carpets, include a composite backing layer 11 and a pile layer 12 glued on the composite backing layer 11. The composite bottom and back layer 11 can be made of materials such as PVC, and the pile layer 12 can be made of materials such as nylon, polyester fiber, etc., but the carpet itself should be the prior art, which will not be repeated here.

The carpet metal sticker 20 for fixing the carpet includes a base plate 21, four hook and loop carpet areas 22 arranged on one side of the base plate 10, and an adhesive layer arranged on the other side of the base plate 21 twenty three. The substrate 21 can be round, square, or any shape, which can be set according to the shape of the actual use occasion. In this embodiment, the substrate 21 is square, which only illustrates the structure of the carpet metal sticker 20. The substrate 21 may be made of metal or non-metal. When the substrate 21 is made of non-metal, it can be made of materials such as plastic, and it is easy to shape, so that the material cost can be reduced. When the substrate 21 is made of metal, such as aluminum alloy, it can reduce the process flow, which will be described in detail below. The four hanging carpet areas 22 can have the same structure and shape, of course, they can also have different structures and shapes, for example, when the size of the carpet 10 to be installed is different. In this embodiment, the four hooked carpet areas 22 have the same structure and shape, that is, the four hooked carpet areas 22 bisect the substrate 21. On a square substrate 21, each of the tapered carpet areas 22 may be square, that is, four tapered carpet areas 22 with a square shape form the substrate 21. Each of the hanging carpet areas 22 may also be triangular, that is, the base plate 21 is composed of four hanging carpet areas with a triangular shape. It is conceivable that the hanging carpet area 22 may also be other polygons. In this embodiment, each of the hanging carpet areas 22 is a triangle, the triangle is an isosceles triangle, and the base of the triangle is the length of the side of the substrate 21. The four hanging carpet areas 22 intersect at a central point 24, and the base plate 21 further includes a central axis 211 that passes through the central point and is perpendicular to the plane where the base plate 21 is located. The center point 24 is used as a reference to install the carpet 10, that is, when the carpet 10 is installed, the corners of the four carpets 10 should be located on the center point 24 as much as possible to ensure the installation stability of the carpet 10. The central shaft 211 is used as a reference for setting the hooking needle teeth 221 provided on the hooking carpet area 22. Each of the hanging carpet areas 22 includes a plurality of hooking needle teeth 221 made of metal materials extending from the base plate 21. The angle between the extension direction of the hooking needle teeth 221 and the central axis 211 is an acute angle, and the acute angle is between 70 degrees and 80 degrees. In this embodiment, the angle between the extending direction of the hooking needle teeth 221 and the central axis 211 is 75 degrees. The angle setting of the hooking needle teeth 221 not only enables the hooking needle teeth 221 to be inserted into the composite backing layer 11 of the carpet 10, but also enables the hooking needle teeth 221 to be hit by a hammer. During the process, the composite bottom back layer 11 will not be extended. Therefore, the length of the hooking needle teeth 221 along its extension direction should be equal to the thickness of the composite backing layer 11, so that the hooking needle teeth 221 will not protrude from the composite backing anyway. The layer 11 enters the pile layer 12. The hook teeth 221 may be made of aluminum alloy. Specifically, the hook teeth 221 and the base plate 21 are integrally formed, that is, the base plate 21 is also made of metal, that is, made of aluminum alloy. It is understandable that the hook teeth can be punched out from the base plate 21 by stamping. This manufacturing method can reduce the process flow and save the manufacturing cost. Of course, the hook teeth 211 can also be fixed on the base plate 21 by welding, riveting, or the like. When the substrate 21 is made of a non-metallic material, when the substrate 21 is injection-molded, a plurality of hook pins 221 should be welded in the substrate 21 at the same time. It is conceivable that each of the hooking needle teeth 221 should have a pointed part, which facilitates insertion into the composite backing layer 11. The hooking needle teeth 221 have sharp tooth tips, and have considerable elasticity and hardness, so that they can pierce the PVC back of carpets and non-woven asphalt carpets. The hooking needle teeth 221 on each hook and loop carpet area 22 should be arranged at intervals so that the hooking needle teeth 221 and the composite backing layer 11 can be coupled to each other. The hooking needle teeth 221 on the two adjacent carpet areas 22 should be arranged at intervals to prevent the hooking needle teeth 221 from protruding from the junction of two adjacent carpets 11, causing the hooking needle teeth 221 It is exposed, causing the installation of the carpet 10 to fail.

The adhesive layer 23 can use a suitable double-sided tape in the prior art, and the double-sided tape can be used for different applications and different glues can be selected. Of course, it is conceivable that when the metal carpet tile 20 is not in use, a layer of release paper is adhered to the adhesive layer 23. When in use, first sprinkle the release paper, and then glue the side of the substrate 21 with the adhesive layer 23 to the floor, such as cement floor, wooden floor, porcelain tile floor, metal floor and plastic floor, etc. Thus, the metal carpet sticker 20 can be fixed.

When installing the carpet 10, when one corner of at least one carpet 10 is placed on the corresponding tapered carpet area 22, a tool such as a hammer can be used to hit the carpet on the tapered carpet area. , So that when the carpet 10 is fixed on the hooked carpet area 22, the hooking needle teeth 221 inserted into the composite bottom back layer 11 and bend and fall, in Figure 1 the hook The needle tooth 221 is arc-shaped, which is only for illustration, and is not necessarily arc-shaped in practice. However, due to the striking of the hammer and the angle between the extension direction of the hook teeth and the central axis is an acute angle, the hook teeth 221 will be contained in the composite backing layer 11, Without extending the composite bottom back layer 11.

Compared with the prior art, the carpet fixing structure provided by the present invention uses the carpet metal sticker 20. The carpet metal sticker 20 is divided into four hanging carpet areas 22, and the four hanging carpet areas 22 are gathered together. The center point 24, so that when the four corners of the four carpet tiles 10 are attached to the four hook and loop carpet areas 22, they can be aggregated into a whole piece. However, since each of the hooked carpet areas 22 is provided with a plurality of hooking needle teeth 221, the angle between the extending direction of the hooking needle teeth 221 and the central axis of the base plate 21 is between 70 degrees and 80 degrees. , So that when the carpet 10 is attached to the carpet area 22, and then the carpet 10 on the carpet area 22 is hit with a hammer, the hook teeth 221 can be inserted into the carpet 10 of the composite backing layer 11, and the length of the hooking needle teeth 221 along its extension direction is equal to the thickness of the composite backing layer 11, so that the hooking needle teeth 221 will not extend out of the composite backing layer 11. At the same time, the hooking needle teeth 221 will bend and fall down when hitting, so that the hooking needle teeth 221 can buckle the composite backing layer 11 of the carpet 10. The other side of the carpet metal sticker 20 is provided with an adhesive layer 23, which can be adhered to the floor, so as to avoid the phenomenon of angle and displacement of the carpet.

The above are only preferred embodiments of the present invention, and are not used to limit the protection scope of the present invention. Any modification, equivalent replacement or improvement within the spirit of the present invention, etc. are all covered by the scope of the claims of the present invention.
