Description

Technical Field

[0001] The utility model relates to the field of artificial turf, in particular to an artificial turf with a fixing device. Background Art

[0002] Artificial turf is a chemical product with the movement properties of natural grass and artificial grass blades implanted in a woven base fabric with a fixing coating on the back. It is widely used in sports and leisure venues. When people walk or run across the artificial turf, they may lift it up, causing the artificial turf to move, which requires fixing the position of the artificial turf.

[0003] Common artificial turf with fixing devices only has the function of fixing the position of the artificial turf. It can fix the position of the artificial turf, but lacks the function of damage-free recycling and cannot guarantee the efficiency of artificial turf recycling. When the artificial turf is recycled and disassembled, it is easy to encounter huge resistance when it is taken out due to the hook structure inserted into the ground, which affects the recycling efficiency.

[0004] Therefore, in view of the lack of the damage-free recovery function of the artificial turf with the fixing device mentioned above, an artificial turf with a fixing device can be designed. By rotating the limit rod, the outer screw is screwed out of the interior of the inner screw fixing part, and then the limit rod is upwardly removed from the interior of the inner cavity. During the upward removal of the limit rod, the limit hook will be pushed by the extended groove and retracted into the interior of the limit groove until it enters the interior, thereby separating the limit hook from the soil, ensuring that the fixing rod will not encounter resistance when it is removed upward from the soil. Utility Model Content

[0005] In order to overcome the common artificial turf with fixed devices, the function of non-destructive recycling is lacking and the efficiency of artificial turf recycling cannot be guaranteed. When the artificial turf is recycled and disassembled, it is easy to encounter huge resistance when it is taken out due to the hook structure inserted into the ground, which affects the recycling efficiency.

[0006] The technical solution of the utility model is: an artificial turf with a fixing device, comprising a base layer; further comprising a buffer layer, a turf layer, a fixed slot, a fixed insertion rod, an inner cavity, a limit rod, a limit slot, a rotating shaft and a limit hook, wherein a buffer layer is provided on the top of the base layer, a turf layer is provided on the top of the buffer layer, a fixed slot is provided at the top center point of the base layer, a fixed insertion rod is provided inside the fixed slot, an inner cavity is provided inside the fixed insertion rod, a limit rod is provided inside the inner cavity, a limit slot is provided through the lower part of the limit rod, two rotating shafts are symmetrically provided on the left and right sides of the inner limit slot, and the two rotating shafts are symmetrically fitted with limit hooks respectively.

[0007] Preferably, the outer screw is screwed out of the inner screw fixing part by rotating the limit rod, and then the limit rod is taken out upward from the inner cavity. During the process of taking the limit rod out upward, the limit hook will be pushed by the extended slot to shrink toward the inner part of the limit slot until it enters the inner part, thereby separating the limit hook from the soil, ensuring that the fixed insertion rod will not encounter resistance when it is taken out from the soil. This solves the problem that common artificial turfs with fixing devices only include the function of fixing the position of artificial turf and can fix the position of artificial turf laying, but lack the function of damage-free recycling and cannot guarantee the efficiency of artificial turf recycling. When the artificial turf is recycled and disassembled, it is easy to encounter huge resistance when it is taken out due to the hook structure inserted in the soil, affecting the recycling efficiency.

[0008] Preferably, an inner screw fixing piece is provided at the inner bottom end of the inner cavity, and an outer screw is provided at the bottom end of the limiting rod. The limiting rod is screwed into the inner screw fixing piece through the outer screw and is fixed to the fixed rod.

[0009] Preferably, two extended slots are symmetrically provided on the left and right sides of the fixed rod body corresponding to the positions of the limit hooks, and two top blocks are symmetrically provided on the left and right sides of the inner wall of the inner cavity corresponding to the positions of the extended slots.

[0010] Preferably, the two limiting barbs extend through the slot at one end away from the limiting rod and are placed on the outside of the fixed rod, and a cone head is provided at the bottom end of the fixed rod.

[0011] Preferably, a number of artificial fiber grasses are arranged at equal intervals on the top of the turf layer, a number of drainage holes are opened at equal intervals on the top of the base layer, buffer layer and turf layer corresponding to the positions of the artificial fiber grass, and lawn edge sealing is provided on the four sides of the base layer, buffer layer and turf layer.

[0012] Preferably, the artificial fiber grass is made of woven nylon material, the lawn edge is made of polypropylene synthetic fiber material, and the lawn edge is adhered to the base layer, the buffer layer and the turf layer by epoxy resin glue.

[0013] Preferably, the base layer is made of asphalt, the buffer layer is made of rubber, and the turf layer is made of leaf-shaped polypropylene fiber.

[0014] Beneficial effects of the utility model:

[0015] 1. The outer screw is screwed out of the inner screw fixing part by rotating the limit rod, and then the limit rod is taken out upward from the inner cavity. During the upward removal of the limit rod, the limit hook will be pushed by the extended slot to shrink into the inner part of the limit slot until it enters the inner part, thereby separating the limit hook from the soil, ensuring that the fixed insertion rod will not encounter resistance when it is taken out from the soil. This solves the problem that common artificial turfs with fixing devices only include the function of fixing the position of artificial turf and can fix the position of artificial turf laying, but lack the function of damage-free recycling and cannot guarantee the efficiency of artificial turf recycling. When the artificial turf is recycled and disassembled, it is easy to encounter huge resistance when it is taken out due to the hook structure inserted in the soil, which affects the recycling efficiency.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See also Figure 1-Figure 4The utility model provides an embodiment: an artificial turf with a fixing device, comprising a base layer 1; further comprising a buffer layer 2, a turf layer 3, a fixed slot 4, a fixed insertion rod 5, an inner cavity 6, a limiting rod 8, a limiting slot 9, a rotating shaft 10 and a limiting hook 11. The buffer layer 2 is provided on the top of the base layer 1, and the turf layer 3 is provided on the top of the buffer layer 2. The center point of the top of the base layer 1, the buffer layer 2 and the turf layer 3 is provided with a fixed slot 4, the interior of the fixed slot 4 is provided with a fixed insertion rod 5, the interior of the fixed insertion rod 5 is provided with an inner cavity 6, the interior of the inner cavity 6 is provided with a limiting rod 8, and a limiting slot 9 is provided through the lower part of the limiting rod 8. Two rotating shafts 10 are symmetrically provided on the left and right sides of the limiting slot 9, and the limiting hooks 11 are symmetrically set on the two rotating shafts 10. The limit rod 8 is turned so that the outer screw 12 is screwed out of the interior of the inner screw fixing part 7, and then the limit rod 8 is taken out upward from the interior of the inner cavity 6. During the process of taking the limit rod 8 out upward, the limit hook 11 is pushed by the extending groove 13 to shrink toward the interior of the limit groove 9 until it enters the interior thereof, thereby separating the limit hook 11 from the soil, ensuring that the fixing rod 5 will not encounter resistance when it is taken out upward from the soil, so as to solve the problem that the common artificial turf with a fixing device only includes the function of fixing the position of the artificial turf and can fix the position of the artificial turf, but lacks the function of damage-free recycling and cannot guarantee the efficiency of the artificial turf recycling. When the artificial turf is recycled and disassembled, it is easy to encounter huge resistance when it is taken out due to the hook structure inserted in the soil, thereby affecting the recycling efficiency.

[0023] See also Figure 2-Figure 4In this embodiment, the two limiting hooks 11 extend through the slot 13 at one end away from the limiting rod 8 and are placed on the outside of the fixed insertion rod 5. The bottom end of the fixed insertion rod 5 is provided with a cone head 15. A number of artificial fiber grasses 16 are evenly spaced on the top of the turf layer 3. A number of drainage holes 17 are evenly spaced and penetrated at the positions corresponding to the artificial fiber grasses 16 on the tops of the base layer 1, the buffer layer 2 and the turf layer 3. Lawn sealing edges 18 are provided on the four sides of the base layer 1, the buffer layer 2 and the turf layer 3. The artificial fiber grass 16 is woven from nylon material, and the lawn sealing edge 18 is made of polypropylene synthetic fiber material. The lawn sealing edge 18 is adhered to the base layer 1, the buffer layer 2 and the turf layer 3 by epoxy resin glue. The base layer 1 is made of asphalt material, the buffer layer 2 is made of rubber material, and the turf layer 3 is made of leaf-shaped polypropylene fiber material. When laying the artificial turf, the fixing rod 5 is inserted into the soil through the cone head 15, and then the base layer 1, the buffer layer 2 and the turf layer 3 are laid flat on the soil surface, and the limiting rod 8 is inserted into the inner cavity 6 of the fixing rod 5. Subsequently, the outer screw 12 is screwed into the inner screw fixing part 7 by rotating the limiting rod 8. When the outer screw 12 is screwed into the inner screw fixing part 7, it will drive the limiting rod 8 to move downward, and the limiting rod 8 will drive the limiting barb 11 to move downward. When the limiting barb 11 moves downward, it will be supported by the top block 14. After being supported by the top block 14, the limiting barb 11 will rotate around the rotating shaft 10 to the extended slot 13 until the two limiting barbs 11 are away from the end of the limiting rod 8 and penetrate the extended slot 13 and insert into the soil, so as to fix the position of the artificial turf and complete the operation of fixing the artificial turf.

[0024] See also Figure 1-Figure 4 In this embodiment, an internal screw fixing part 7 is provided at the bottom end of the inner cavity 6, and an external screw 12 is provided at the bottom end of the limiting rod 8. The limiting rod 8 is screwed into the inner part of the internal screw fixing part 7 and fixed to the fixed plug rod 5 through the external screw 12. Two extended slots 13 are symmetrically provided on the left and right sides of the fixed plug rod 5 corresponding to the position of the limiting barb 11. Two top blocks 14 are symmetrically provided on the left and right sides of the inner wall of the inner cavity 6 corresponding to the position of the extended slot 13. When the artificial turf needs to be recycled, the external screw 12 is unscrewed out of the internal screw fixing part by rotating the limiting rod 8. 7, and then the limiting rod 8 is taken out upward from the inner cavity 6. During the upward removal of the limiting rod 8, the limiting hook 11 is pushed by the extending groove 13 to retract into the limiting groove 9 until it enters the inner portion, thereby separating the limiting hook 11 from the soil, ensuring that the fixed insertion rod 5 will not encounter resistance when it is taken out upward from the soil, realizing the function of damage-free recycling, and preventing the problem that the barb structure inserted into the soil will cause huge resistance when it is taken out during the recycling and disassembly of the artificial turf, thereby affecting the recycling efficiency.

[0025] When working, the fixed plug rod 5 is inserted into the soil through the cone head 15, and then the base layer 1, the buffer layer 2 and the turf layer 3 are laid flat on the soil surface, and then the limiting rod 8 is inserted into the inner cavity 6 of the fixed plug rod 5, and then the outer screw 12 is screwed into the inner screw fixing part 7 by rotating the limiting rod 8. When the outer screw 12 is screwed into the inner screw fixing part 7, it will drive the limiting rod 8 to move downward, and the limiting rod 8 will drive the limiting barb 11 to move downward. When the limiting barb 11 moves downward, it will be supported by the top block 14. After being supported by the top block 14, the limiting barb 11 will rotate around the rotating shaft 10 to the extended slot 13 until The two limiting hooks 11 are inserted into the soil at one end away from the limiting rod 8 through the extension groove 13 to fix the position of the artificial turf. When the artificial turf needs to be recovered, the limiting rod 8 is rotated to make the outer screw 12 screw out of the inner screw fixing part 7, and then the limiting rod 8 is taken out upward from the inner cavity 6. During the upward removal of the limiting rod 8, the limiting hook 11 will be pushed by the extension groove 13 to shrink toward the inside of the limiting groove 9 until it enters the inside, thereby separating the limiting hook 11 from the soil, ensuring that the fixing rod 5 will not encounter resistance when it is taken out upward from the soil, thereby realizing the function of damage-free recovery.

[0026] Through the above steps, the outer screw 12 is screwed out of the interior of the inner screw fixing part 7 by rotating the limit rod 8, and then the limit rod 8 is taken out upward from the interior of the inner cavity 6. During the process of taking the limit rod 8 upward, the limit hook 11 will be pushed by the extending groove 13 to shrink toward the interior of the limit groove 9 until it enters the interior, thereby separating the limit hook 11 from the soil, ensuring that the fixed insertion rod 5 will not encounter resistance when it is taken out upward from the soil, so as to solve the problem that the common artificial turf with a fixing device only includes the function of fixing the position of the artificial turf and can fix the position of the artificial turf, but lacks the function of damage-free recycling and cannot guarantee the efficiency of the artificial turf recycling. It is easy to encounter huge resistance when the artificial turf is taken out due to the hook structure inserted in the soil during recycling and disassembly, thereby affecting the recycling efficiency.
