Description

Technical Field

[0001] The utility model relates to the technical field of artificial turf, in particular to an artificial turf with high elasticity. Background Art

[0002] Artificial turf is divided into injection-molded artificial turf and woven artificial turf according to the production process. Artificial turf can be used in running tracks, football fields, tennis courts, baseball fields, hockey fields, gateball courts, golf courses, basketball courts, volleyball courts, badminton courts, softball fields and other sports venues. However, the existing artificial turf has a simple structure and poor elasticity, which cannot meet the needs of users.

[0003] Therefore, the prior art proposes an elastic artificial turf for sports fields with application number 201821230914.7. The shock-absorbing elastic pad and the reset spring sheet are arranged, which can absorb the force of people stepping on the lawn, and after the absorption force reaches the limit, an upward lifting force will be generated, thereby achieving the purpose of improving the elasticity of the lawn.

[0004] However, during the actual use of this type of artificial turf, the reset spring piece may extend outward after being bent downward and deformed by force, causing the reset spring piece to be unable to return to its position normally, making the rebound effect of the artificial turf unsatisfactory, and further making the artificial turf not have high elasticity. Utility Model Content

[0005] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes an artificial lawn with high elasticity.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A high-elastic artificial turf comprises a mounting frame and an artificial turf cloth layer, wherein the artificial turf cloth layer is tightly attached to the top of the mounting frame, main reinforcing ribs and secondary reinforcing ribs are fixed to the uppermost part of the interior of the mounting frame, a connecting plate is rotatably connected to the bottom of the main reinforcing ribs, a supporting plate is fixed to the lower part of the interior of the mounting frame, a buffer spring and a buffer column are vertically fixed to the top and bottom of the connecting plate respectively, a supporting rod is vertically fixed to the bottom of the mounting frame, a buffer pad is fixed to the top of the supporting rod, an outer spring is nested below the outer side of the supporting rod, a fixing tube is nested above the outer side of the supporting rod, and a connecting column is fixed to the outer wall of the fixing tube.

[0008] Preferably, the main reinforcing ribs and the secondary reinforcing ribs are respectively in a "cross" shape and an "X" shape and are tightly attached to the bottom of the artificial turf cloth layer, the secondary reinforcing ribs are fixed between the main reinforcing ribs and the inner wall of the mounting frame, and the main reinforcing ribs and the secondary reinforcing ribs are both made of elastic material.

[0009] Preferably, connecting plates are connected to the front, rear, left, and right ends of the bottom of the main reinforcing rib. The lower side of the outer side of the connecting plate is connected to the support plate. The connecting plate is arranged in an inclined shape with a lower outer side and a higher middle at the bottom end of the main reinforcing rib.

[0010] Preferably, the top of the buffer spring on the support plate is connected to the main reinforcing rib. The bottom of the buffer column below the support plate is connected to the bottom of the installation frame. The buffer column is made of an elastic material.

[0011] Preferably, the connecting column on the fixed cylinder is connected to the outer side of the bottom of the secondary reinforcing rib. The middle parts of the support rod and the secondary reinforcing rib are both in the same vertical horizontal plane. The support rod is arranged in an inclined shape with a higher outer side and a lower middle at the bottom of the secondary reinforcing rib.

[0012] Preferably, the top of the outer spring is closely attached to the bottom end of the fixed cylinder. The outer wall of the support rod is closely attached to the fixed cylinder. The fixed cylinder moves up and down in the vertical direction on the outer wall of the support rod.

[0013] 1. When stepping on the artificial turf layer, the artificial turf layer is forced to squeeze the main reinforcing rib and the secondary reinforcing rib downward. The elastic main reinforcing rib and secondary reinforcing rib are deformed by the force. When the main reinforcing rib is deformed by the force, it squeezes the buffer spring at the upper end of the connecting plate to deform. When the secondary reinforcing rib is deformed by the force, it squeezes the fixed cylinder to move downward on the outer side of the support rod through the connecting column, and squeezes the outer spring below the outer side of the support rod to compress and deform. Subsequently, the compressed buffer spring, outer spring, main reinforcing rib, and secondary reinforcing rib will simultaneously generate a large rebound force to push the artificial turf layer upward. The resilience is relatively high, thereby making the artificial lawn have high elastic performance.

[0014] 2. When a relatively large force steps on the artificial turf layer, the artificial turf layer is forced to squeeze the main reinforcing rib and the secondary reinforcing rib downward. The elastic main reinforcing rib and secondary reinforcing rib are deformed by a relatively large force. When the main reinforcing rib is deformed by a relatively large force, it will push the connecting plate downward and squeeze the buffer column at the lower end of the connecting plate to prevent the main reinforcing rib from further bending and moving downward. When the secondary reinforcing rib is deformed by a relatively large force, the fixed cylinder will contact the bottom end of the installation frame. At the same time, the buffer pad at the top of the support rod will contact the bottom of the secondary reinforcing rib to prevent the secondary reinforcing rib from further bending and moving downward, making the artificial lawn effectively improve the strength of the artificial lawn while having high elasticity, and preventing the main reinforcing rib and the secondary reinforcing rib from being damaged and broken under the action of a relatively large force.

Detailed implementation method

[0021] Example 1, referring to Figures 1-4 A highly elastic artificial turf, comprising an installation frame 1 and an artificial turf layer 101. The top of the installation frame 1 is closely attached to the artificial turf layer 101. At the uppermost part inside the installation frame 1, a main reinforcing rib 2 and a secondary reinforcing rib 201 are fixed. The bottom of the main reinforcing rib 2 is rotatably connected to a connecting plate 3. A support plate 301 is fixed at the lower part inside the installation frame 1. A buffer spring 302 and a buffer column 303 are vertically fixed to the top and bottom of the connecting plate 3 respectively. A support rod 4 is vertically fixed to the bottom of the installation frame 1. A buffer pad 401 is fixed to the top of the support rod 4. An outer spring 402 is nested below the outer side of the support rod 4, and a fixed cylinder 403 is nested above the outer side of the support rod 4. A connecting column 404 is fixed to the outer wall of the fixed cylinder 403.

[0022] The main reinforcing rib 2 and the secondary reinforcing rib 201 are respectively in a "cross" shape and an "X" shape and are closely attached to the bottom of the artificial turf layer 101. The secondary reinforcing rib 201 is fixed between the main reinforcing rib 2 and the inner wall of the installation frame 1. Both the main reinforcing rib 2 and the secondary reinforcing rib 201 are made of elastic materials;

[0023] The main reinforcing rib 2 and the secondary reinforcing rib 201 are fixedly connected together to form a whole, so that when the artificial turf layer 101 moves downward, the main reinforcing rib 2 and the secondary reinforcing rib 201 can be stressed and deformed simultaneously;

[0024] When stepping on the artificial turf layer 101, the artificial turf layer 101 is stressed and presses down on the main reinforcing rib 2 and the secondary reinforcing rib 201. The elastic main reinforcing rib 2 and secondary reinforcing rib 201 are stressed and deformed. When the main reinforcing rib 2 is stressed and deformed, it presses the buffer spring 302 at the upper end of the connecting plate 3 to deform. Subsequently, the compressed buffer spring 302 and the main reinforcing rib 2 will simultaneously generate a large rebounding force to push the artificial turf layer 101 upward. The resilience is relatively high, and thus the artificial turf of the present invention has high elastic performance;

[0025] The front, rear, left, and right ends at the bottom of the main reinforcing rib 2 are all connected with connecting plates 3. The lower outer side of the connecting plate 3 is connected to the support plate 301. The connecting plate 3 is arranged in an inclined shape with a lower outer side and a higher middle part at the bottom end of the main reinforcing rib 2;

[0026] The top of the buffer spring 302 on the support plate 301 is connected to the main reinforcing rib 2. The bottom of the buffer column 303 below the support plate 301 is connected to the bottom of the installation frame 1. The buffer column 303 is made of an elastic material;

[0027] When a relatively large force steps on the artificial turf layer, the artificial turf layer is forced to press down on the main reinforcing rib 2 and the secondary reinforcing rib 201. The elastic main reinforcing rib 2 and secondary reinforcing rib 201 deform under the relatively large force. When the secondary reinforcing rib 201 deforms under the relatively large force, the fixing cylinder 403 will contact the bottom end of the installation frame 1. At the same time, the buffer pad 401 at the top of the support rod 301 will contact the bottom of the secondary reinforcing rib 201 to prevent the secondary reinforcing rib 201 from further bending and moving downwards, so that the artificial turf can effectively improve the strength of the artificial turf while having high elasticity, and prevent the main reinforcing rib 2 and the secondary reinforcing rib 201 from being damaged and broken under the action of a relatively large force.

[0028] Embodiment 2. The difference between Embodiment 2 and Embodiment 1 is that in this embodiment, the connecting column 404 on the fixing cylinder 403 is connected to the outer side of the bottom of the secondary reinforcing rib 201. The middle parts of the support rod 4 and the secondary reinforcing rib 201 are both on the same vertical horizontal plane. The support rod 4 is arranged in an inclined shape with a higher outer side and a lower middle part at the bottom of the secondary reinforcing rib 201;

[0029] When stepping on the artificial turf layer 101, the artificial turf layer 101 is forced to press down on the main reinforcing rib 2 and the secondary reinforcing rib 201. The elastic main reinforcing rib 2 and secondary reinforcing rib 201 are deformed by the force. When the secondary reinforcing rib 201 is deformed by the force, it squeezes the fixing cylinder 403 to move downwards on the outer side of the support rod 4 through the connecting column 404, and squeezes the outer spring 402 below the outer side of the support rod 4 to be compressed and deformed. Subsequently, the compressed outer spring 402 and the secondary reinforcing rib 201 will simultaneously generate a relatively large rebounding force to push the artificial turf layer upwards, and the resilience is relatively high, thereby making the artificial turf have high elastic performance;

[0030] The top of the outer spring 402 is closely attached to the bottom end of the fixing cylinder 403. The outer wall of the support rod 4 is closely attached to the fixing cylinder 403. The fixing cylinder 403 moves up and down in the vertical direction on the outer wall of the support rod 4;

[0031] When a relatively large force steps on the artificial grass cloth layer 101, the artificial grass cloth layer 101 is forced to squeeze the main reinforcing ribs and the auxiliary reinforcing ribs downward. The elastic main reinforcing rib 2 and the auxiliary reinforcing rib 201 are deformed under the relatively large force. When the auxiliary reinforcing rib 201 is deformed under the relatively large force, the fixing cylinder 403 will move down along the support rod 4 to contact the bottom end of the installation frame 1. At the same time, the buffer pad 401 at the top of the support rod 4 will contact the bottom of the auxiliary reinforcing rib 201 to prevent the auxiliary reinforcing rib 201 from further bending and moving downward, so that the artificial turf can effectively improve the strength of the artificial turf while having high elasticity, and prevent the main reinforcing rib 2 and the auxiliary reinforcing rib 201 from being damaged and broken under the action of a relatively large force.

[0032] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
