Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of artificial turf, and in particular relates to a splicable unit turf carpet. Background Art
[0002] Artificial turf (carpet) refers to a chemical product with natural grass motion performance that is implanted in a woven base fabric with synthetic fibers that imitate grass leaves and coated on the back with a fixing coating. It is widely used in sports and leisure venues. At present, when laying artificial turf, multiple pieces of turf are generally laid on the ground close to each other. There are many problems with this laying method. For example, after laying the turf on the court or sports field, since the bottom surface of the artificial turf is a backing layer, the friction with the ground is relatively small. During use, the turf unit is easy to slide out of position. In addition, the edges or corners of the turf are also prone to warping, affecting the user experience. If it is not maintained frequently, the entire turf will be messy and difficult to maintain after long-term use, and re-laying will greatly increase the cost. It is very necessary to design a stable spliced turf carpet. Utility Model Content

[0020] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.
[0021] The technical solution of the utility model is described in detail below with specific embodiments.
[0022] The utility model provides a splicable unit lawn carpet, comprising a square lawn body, such as Figure 1 As shown, the lawn body includes a surface layer 1, a base fabric 2, an adhesive layer 3 and an adhesive layer 4. The surface layer 1 is an artificial grass silk layer woven on the base fabric 2. The adhesive layer 3 is arranged on the bottom surface of the base fabric 2 to cover the stitches of the surface layer 1 so that the surface layer 1 and the base fabric 2 are fixedly connected. The bottom surface of the adhesive layer 3 is provided with anti-slip textures, wherein the adhesive layer 3 is a PVC foam adhesive layer or a PU foam adhesive layer with a thickness of 2 to 8 mm, preferably 3 to 6 mm. The adhesive layer 3 is thick and wear-resistant, which can prevent warping and improve the fitting performance during splicing.
[0023] In some embodiments, the base fabric 2 is a long-fiber nonwoven fabric with a weight of 90 to 140 g / m 2 , the long fiber nonwoven fabric of this weight has the advantage of high flatness and can prevent warping.
[0024] In some embodiments, the surface layer 1 is an artificial grass layer made of PP or PA material, with a weight of 5000 dtex, ie, 5 kg / 10000 m.
[0025] In some embodiments, the density specification of the surface layer 1 is / 16 inch to 5 / 32 inch row spacing to ensure sufficient density of grass fibers.
[0026] In the present invention, the anti-slip pattern can increase the friction between the lawn carpet and the ground, and in order to further position the lawn carpet and prevent displacement during use, in some embodiments, such as Figure 2 As shown, the splicable unit lawn carpet also includes an auxiliary splicing component, which is used in conjunction with the adhesive layer 3. The auxiliary splicing component includes a corner fixing block 5. The corner fixing block 5 is rectangular, preferably square, and is fixed to the ground. The four corners of the adhesive layer 3 are all provided with docking grooves that are adapted to the corners of the corner fixing block 5. The drawings do not show that the area of the docking groove is equal to one-fourth of the area of the corner fixing block 5. It is easy to understand that the corner fixing block 5 is divided into four rectangular areas of equal shape and area based on the center. Each rectangular area is adapted to the docking groove of the adhesive layer 3 of the unit lawn carpet, that is, one corner fixing block 5 can be connected to four unit lawn carpets, so that the four unit lawn carpets are tightly spliced at the corner fixing block 5.
[0027] The corner fixing block 5 can be a metal part or a plastic part. Preferably, the corner fixing block 5 is a plastic part, which can reduce the cost and avoid the problem of rust. The four corners of the corner fixing block 5 are all provided with connection holes, which are fixedly connected to the ground or other planes by screws.
[0028] It is easy to understand that since the corner fixing block 5 is partially embedded in the docking groove of the adhesive layer 3, the displacement of the unit lawn carpet can be effectively prevented. The corner fixing block 5 and the docking groove of the adhesive layer 3 can be unfixed, or can be fixed by bonding, or the corner fixing block 5 and the docking groove of the adhesive layer 3 can be connected by a structure such as Velcro, which is convenient for disassembly and replacement.
[0029] Furthermore, the thickness of the corner fixing block 5 is equal to the depth of the docking groove of the adhesive layer 3, so as to avoid the bulges at the four corners of the unit lawn carpet, and the top surface of the corner fixing block 5 is a rough surface, so as to increase the friction between the corner fixing block 5 and the adhesive layer 3. Under the action of the adhesive layer 4 and the blocking action of the corner fixing block 5, the displacement of the unit lawn carpet can be effectively prevented.
[0030] In some embodiments, the auxiliary splicing assembly further includes a steel wire 9, a central circular groove 6 is provided at the center of the top surface of the corner fixing block 5, a positioning column 7 is provided in the central circular groove 6, a gap exists between the positioning column 7 and the inner side wall of the central circular groove 6, and connecting grooves 8 are respectively provided between the positioning column 7 and the four sides of the corner fixing block 5, the connecting grooves 8 are connected to the central circular groove 6, and the connecting grooves 8 are perpendicular to the edges on the same side of the corner fixing block 5, and the steel wire 9 is provided between the positioning columns 7 of two adjacent corner fixing blocks 5 along the connecting grooves 8. The steel wire 9 is actually located between two adjacent unit lawn carpets, and plays a role in preventing the unit lawn carpets from moving.
[0031] It is easy to understand that in order to prevent the positioning column 7 from affecting the laying of the unit lawn carpet, the height of the top surface of the positioning column 7 is less than or equal to the height of the top surface of the corner fixing block 5.
[0032] Furthermore, in order to facilitate the fixing of the steel wire 9 , a plurality of annular grooves are provided on the side surface of the positioning column 7 from top to bottom, for the steel wire 9 to be wound around and fixed on the positioning column 7 .
[0033] In the case where the steel wire 9 is provided, after the corner fixing blocks 5 are installed, the steel wire 9 is installed between adjacent corner fixing blocks 5. Specifically, the two ends of the steel wire 9 are wound around the positioning posts 7 of the two corner fixing blocks 5 to keep the steel wire 9 in a nearly taut state. The corner fixing blocks 5 corresponding to the four corners of a unit lawn carpet form a square area through the steel wire 9, which is adapted to the unit lawn carpet. After the unit lawn carpet is laid, the corner fixing blocks 5 and the steel wire 9 have a restrictive effect on the unit lawn carpet, and the unit lawn carpet changes from the previous mutual contact to the contact between the unit lawn carpet and the corner fixing blocks 5. The contact position is no longer the corner, but the position close to the inside of the corner, which also has the effect of preventing the corner from warping. The adhesive layer 3 can also increase the friction between the unit lawn carpet and the ground to limit displacement.
[0034] The embodiments provided by the utility model are described in detail above. Specific examples are used in this article to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the core idea of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
