Description

Technical Field

[0001] This utility model belongs to the field of artificial turf technology, specifically relating to an artificial turf with a non-slip bottom surface. Background Technology

[0002] Artificial turf is widely used in sports fields, landscaping, and commercial spaces due to its maintenance-free nature, strong weather resistance, and wide adaptability. However, traditional turf undersides are mostly single-layer structures of flat base fabric, lacking any micro-grip structures such as protrusions, barbs, or mesh. Friction is generated solely through the contact surface between the base fabric and the ground, and this friction disappears instantly if impurities such as sand or fallen leaves are present. Furthermore, the load-bearing layer of traditional artificial turf undersides is often made of polypropylene, polyethylene, or non-woven fabric. These materials have smooth surfaces and high hardness, resulting in weak adhesion to hard surfaces such as cement and asphalt. When exposed to rain or morning dew, a water film forms on the base fabric surface, causing a sharp drop in the coefficient of friction.

[0003] Chinese patent CN212103547U discloses an anti-slip artificial turf, comprising a backing fabric, artificial grass at the top of the backing fabric, a reinforcing mesh layer and a first connecting strip at the bottom of the backing fabric, the first connecting strip being located at one end of the reinforcing mesh layer, a shock-absorbing layer at the bottom of the reinforcing mesh layer, vibration-damping holes on one side of the shock-absorbing layer penetrating the shock-absorbing layer, a waterproof layer at the bottom of the shock-absorbing layer, an anti-slip layer at the bottom of the waterproof layer, and a protrusion and an anti-slip strip at the bottom of the anti-slip layer, the anti-slip strip being located on one side of the protrusion. This patent, by adding protrusions and anti-slip strips to the bottom of the anti-slip layer, with both protrusions and anti-slip strips made of silicone rubber, possesses heat insulation, electrical insulation, moisture resistance, and good adsorption properties, resulting in a stable structure and long service life. However, the anti-slip effect of this patent relies on the silicone rubber protrusions and anti-slip strips; after repeated installation and disassembly or external pulling, they are prone to elastic fatigue, deformation, or even breakage, leading to loose connections. Utility Model Content

[0004] The purpose of this invention is to provide an anti-slip artificial turf that can reduce the risk of slipping in wet weather and avoid safety hazards caused by the failure of anti-slip components.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An anti-slip artificial turf includes a turf body with artificial grass on it. An anti-slip layer is located at the bottom of the turf body. Several connecting blocks are fixedly installed at the bottom of the turf body in conjunction with the anti-slip layer. Each connecting block includes an upper receiving platform and a lower locking platform, which are integrally formed. Several connecting grooves are provided inside the anti-slip layer in conjunction with the connecting blocks. Each connecting groove has an elastic locking element in conjunction with the locking platform. Several ground stakes are evenly distributed at the top of the turf body. Each ground stake includes a central holding and bearing section, with locking insertion rods fixedly installed at both ends. The locking insertion rods penetrate vertically through the turf body and the anti-slip layer, and have reverse locking barbs.

[0006] Furthermore, the main body of the lawn is equipped with several positioning guide holes in conjunction with the ground stakes, and the positioning guide holes penetrate the main body of the lawn in a vertical direction.

[0007] Furthermore, the anti-slip layer is provided with several through-holes corresponding to several positioning guide holes. The through-holes penetrate the anti-slip layer in a vertical direction and are coaxial with the positioning guide holes.

[0008] Furthermore, the diameter of the positioning guide hole is equal to the diameter of the through mounting hole, and the diameter of the positioning guide hole is greater than the diameter of the locking insertion rod.

[0009] Furthermore, the lower end of the locking insertion rod is provided with a spiked tip.

[0010] Furthermore, both the receiving platform and the locking platform are arranged in an inverted frustum shape, and the axis of the receiving platform and the axis of the locking platform are collinear.

[0011] Furthermore, the cross-sectional area of ​​the bottom surface of the receiving platform is greater than the cross-sectional area of ​​the bottom surface of the clamping platform.

[0012] Furthermore, the connecting groove is cylindrical in shape and has a locking slot.

[0013] Furthermore, the elastic locking element includes a locking plate and an elastic telescopic rod. One end of the elastic telescopic rod is fixedly connected to the connecting groove, and the other end of the elastic telescopic rod is fixedly connected to the locking plate. The elastic locking element is arranged around the engaging slot of the connecting groove.

[0014] Furthermore, anti-slip textures are provided at the bottom of the anti-slip layer.

[0015] The beneficial effects of this utility model are as follows: By connecting the connecting block at the bottom of the turf body and the connecting groove in the anti-slip layer, the stability of the connection between the turf body and the anti-slip layer is improved. When the locking platform is gradually inserted into the locking groove of the connecting groove, the circumferential locking part will expand outward under the squeezing action of the locking platform, providing sufficient space for the locking platform to enter. When the locking platform is fully inserted into the connecting groove, the squeezing force of the locking platform on the elastic circumferential locking part disappears, and the elastic circumferential locking part will retract inward and hug the outer periphery of the receiving platform, thereby achieving a locking effect. After the ground nail is inserted into the soil, the reverse locking barb on the locking insertion rod bites into the soil to form a one-way locking, effectively preventing the ground nail from being pulled out when subjected to external force. The overall fixation is reliable and has strong anti-displacement ability. Attached Figure Description

[0017] The present invention will now be described and illustrated in detail with reference to the embodiments.

[0018] Example 1 like Figure 1-11 As shown, the anti-slip artificial turf includes a turf body 1, on which artificial grass is provided. An anti-slip layer 3 is provided at the bottom of the turf body 1. Several connecting blocks 4 are fixedly provided at the bottom of the turf body 1 in conjunction with the anti-slip layer. The connecting blocks 4 include an upper receiving platform 401 and a lower locking platform 402. The receiving platform 401 and the locking platform 402 are integrally formed. Several connecting grooves 5 are provided inside the anti-slip layer 3 in conjunction with the several connecting blocks 4. An elastic circumferential locking element 6 is provided inside each connecting groove 5 in conjunction with the locking platform 402. Several ground stakes 7 are evenly provided at the top of the turf body 1. The ground stakes 7 include a middle holding and bearing section 701. Locking insertion rods 702 are fixedly provided at both ends of the holding and bearing section 701. The locking insertion rods 702 are set vertically through the turf body 1 and the anti-slip layer 3. Reverse locking barbs 8 are provided on the locking insertion rods 702.

[0019] The connecting block 4 and the connecting groove 5 cooperate, and the interlocking of the locking platform 402 and the elastic ring-locking part 6 can avoid the problem of elastic fatigue and breakage caused by long-term stress, and improve the connection durability between the turf body 1 and the anti-slip layer 3. The holding and bearing section 701 of the ground stake 7 is easy to apply force. After the locking insertion rods 702 at both ends of the ground stake 7 penetrate through the turf body 1 and the anti-slip layer 3, they lock the barbs 8 in the opposite direction and interlock with the soil to form a one-way lock, which effectively resists the displacement caused by external force and solves the problem of traditional turf relying only on the friction of the contact surface to easily slip. The interlayer locking of "connecting block 4-elastic ring-locking part 6" and the overall fixation of "ground stake 7-soil" work together to provide stable support for the anti-slip function of the anti-slip layer 3 and reduce safety hazards in wet environments.

[0020] The lawn body 1 has several positioning guide holes 2 that are set vertically through the lawn body 1 to match the ground stakes 7. The positioning guide holes 2 can be directly aligned with the ground stakes 7 through the positioning guide holes 2, eliminating the need to repeatedly adjust the position of the ground stakes 7, simplifying the installation operation and shortening the construction time.

[0021] The anti-slip layer 3 is equipped with several through-holes 9 corresponding to several positioning guide holes 2. The through-holes 9 penetrate the anti-slip layer 3 vertically and are coaxial with the positioning guide holes 2. The through-holes 9 on the anti-slip layer 3 are coaxial with the positioning guide holes 2 of the lawn body 1, forming a continuous vertical channel. This avoids jamming caused by misalignment of the holes after the locking insertion rod 702 passes through the lawn body 1, ensuring that the locking insertion rod 702 smoothly passes through the lawn body 1 and the anti-slip layer 3 and is inserted into the ground, while simultaneously providing longitudinal fixation for the lawn body 1 and the anti-slip layer 3.

[0022] The diameter of the positioning guide hole 2 is equal to the diameter of the through mounting hole 9, and the diameter of the positioning guide hole 2 is larger than the diameter of the locking insertion rod 702. The larger diameter of the positioning guide hole 2 than the diameter of the locking insertion rod 702 creates a clearance fit, facilitating the quick insertion of the locking insertion rod 702.

[0023] The lower end of the locking insertion rod 702 is provided with a spike tip.

[0024] Both the receiving platform 401 and the locking platform 402 are inverted frustum shapes, and the axis of the receiving platform 401 and the axis of the locking platform 402 are collinear.

[0025] The cross-sectional area of ​​the lower surface of the receiving platform 401 is larger than the cross-sectional area of ​​the upper surface of the engaging platform 402. The receiving platform 401 and the engaging platform 402 form a stepped structure. When the receiving platform 401 abuts against the engaging slot 10 of the connecting groove 5, it can limit the excessive insertion of the engaging platform 402 and avoid squeezing and damaging the elastic ring locking member 6.

[0026] The connecting groove 5 is cylindrical in shape, and a locking slot 10 is provided on the connecting groove 5.

[0027] The elastic circumferential locking element 6 includes a circumferential plate and an elastic telescopic rod. One end of the elastic telescopic rod is fixedly connected to the connecting groove 5, and the other end of the elastic telescopic rod is fixedly connected to the circumferential plate. The elastic circumferential locking element 6 is arranged around the engaging slot 10 of the connecting groove 5. The elastic circumferential locking element 6 is adapted to the engaging platform 402, and can form a circumferential circumferential engagement after the engaging platform 402 is inserted.

[0028] The bottom of the anti-slip layer 3 is provided with anti-slip texture. The anti-slip texture increases the contact area between the anti-slip layer 3 and the ground, reducing the risk of slipping.
