[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] Example 1

[0032] like Figure 1-5 As shown, an embodiment of the present application discloses a geocell node connection structure, including a U-shaped rod body 2, a limiting ring 3 and a connecting assembly 4 passing through the cell sheet 1, and the cell sheet 1 is provided with a strip cut 11 parallel to the extension direction of the cell sheet 1. When in use, the two rod bodies of the U-shaped rod body 2 alternately pass through the multiple strip cuts 11 of adjacent cell sheets 1.

[0033] The limiting ring 3 is a circular ring structure, which is integrally formed with the U-shaped rod body 2 near the end of the U-shaped rod body 2. The outer diameter of the limiting ring 3 decreases from the middle of the limiting ring 3 to both sides (the cross-section of the outside of the limiting ring 3 is semicircular). The limiting ring 3 is located on the outside of the cell sheet 1, and there are two limiting rings 3 and they are respectively located on the two rods of the U-shaped rod body 2.

[0034] The connecting component 4 is arranged on the U-shaped rod body 2, and cooperates with the two limiting rings 3 to prevent the U-shaped rod body 2 from separating from the cell sheet 1. The two rods of the U-shaped rod body 2 alternately pass through the multiple strip cuts 11 of the cell sheet 1. Under the cooperation of the limiting ring 3 and the connecting component 4, the U-shaped rod body 2 cuts the multiple strip cuts 11 of the adjacent cell sheets 1, which produces a larger connecting force on the two connected cell sheets 1, reducing the probability of the connection between the connected cell sheets 1 being loose after the cell sheets 1 are pulled, which is beneficial to extending the service life of the corresponding geocell.

[0035] Specifically, in this embodiment, the connecting assembly 4 includes a stopper 5 and a connecting unit 6. The stopper 5 is a truncated cone-shaped structure, with its smaller diameter end fixed to the end of the U-shaped rod 2. First cutting surfaces 51 are provided on both sides of the stopper 5. Two stoppers 5 are provided, one at each end of the U-shaped rod 2. The connecting unit 6 is mounted on the U-shaped rod 2 and connects the two rods of the U-shaped rod 2. It is located between the stopper ring 3 and the stopper 5 and includes a connecting plate 61 and a first connecting member 62.

[0036] The connecting plate 61 is a rectangular plate-like structure located between the limiting ring 3 and the limiting block 5. A through hole 611 is provided through the connecting plate 61 for the limiting block 5 to pass through. The width of the through hole 611 is greater than or equal to the distance between the first cutting planes 51 on both sides, and the width of the through hole 611 is less than the outer diameter of the limiting ring 3. The first connecting member 62 is located between the connecting plate 61 and the limiting block 5. One side of the first connecting member 62 is provided with a first opening 621 for the U-shaped rod 2 to be inserted into, and a first arcuate groove 622 that communicates with the first opening 621 and is engaged with the U-shaped rod 2. There are two through holes 611, two first openings 621, and two first arcuate grooves 622. The two first openings 621 are arranged in parallel directions. The limiting ring 3, the connecting plate 61, the first connecting member 62, and the limiting block 5 are in contact with each other.

[0037] The limitation of the width of the through hole 611, the distance between the two first cutting planes 51 and the outer diameter of the limiting ring 3 ensures the stability of the connecting plate 61 during use. The limiting ring 3, the connecting plate 61, the first connecting piece 62 and the limiting block 5 cooperate to ensure that the two rods of the U-shaped rod 2 are fixed after passing through the multiple strip cuts 11 of the adjacent cell sheets 1 in sequence, thereby ensuring the stability of the connection between the adjacent cell sheets 1, reducing the probability of the connection between the adjacent cell sheets 1 loosening and deformation after being subjected to force, and helping to extend the service life of the connected geocells.

[0038] Example 2

[0039] like Figure 6 and Figure 7 As shown, the only difference between this embodiment and embodiment 1 is that second cutting planes 52 are provided on both sides of the limit block 5 and the structure of the connecting unit 6 is different. Specifically, the connecting unit 6 is a second connecting member 63 disposed between the limit ring 3 and the limit block 5. One side of the second connecting member 63 is provided with a second opening 631 for the U-shaped rod 2 to be inserted into, and a second arcuate groove 632 that communicates with the second opening 631 and is engaged with the U-shaped rod 2. There are two second openings 631 and two second arcuate grooves 632. The angle between the two second openings 631 is an obtuse angle, and the two sides of the second connecting member 63 respectively abut the limit ring 3 and the limit block 5.

[0040] Combine Figure 2 As shown, when using the second connecting piece 63 to connect the two rod bodies of the U-shaped rod body 2, the staff must first insert one of the rod bodies of the U-shaped rod body 2 into the first arc-shaped groove 622 from the second opening 631, and then insert the other rod body of the U-shaped rod body 2 into the first arc-shaped groove 622 corresponding to the other second opening 631 to complete the installation of the second connecting piece 63. Since the angle between the setting directions of the two second openings 631 is an obtuse angle, the stability of the connection between the U-shaped rod body 2 and the cell sheet 1 is guaranteed under the cooperation of the limit ring 3, the second connecting piece 63 and the limit block 5.

[0041] Example 3

[0042] like Figure 8 As shown, the only difference between this embodiment and Example 1 is the different composition and structure of the connecting unit 6, and the lack of a corresponding cutting plane on the stop block 5. Specifically, the connecting unit 6 is a third connecting member 64 disposed between the stop ring 3 and the stop block 5. The third connecting member 64 is provided with a hole 641 through which the U-shaped rod 2 passes. The holes 641 are provided in two symmetrical arrangements. The diameter of the stop block 5 is greater than or equal to the diameter of the holes 641. The two sides of the third connecting member 64 respectively abut the stop ring 3 and the stop block 5.

[0043] Combine Figure 2 As shown, after the staff alternately passes the two rods of the U-shaped rod 2 through the multiple strip cuts 11 of the two cell sheets 1, the staff must first pass the two ends of the U-shaped rod 2 through the two holes 641 on the third connecting member 64, and then use a stamping device to punch out the two ends of the U-shaped rod 2 and form a limit block 5 (in other embodiments, the limit block 5 can also be formed by this method) to complete the connection and fixation between the U-shaped rod 2 and the cell sheet 1.

[0044] Example 4

[0045] like Figure 9 As shown, the difference between this embodiment and embodiment 1 is:

[0046] 1. The U-shaped rod body 2 is provided with a bent portion 7 near its two ends. Both ends of the U-shaped rod body 2 extend toward one side close to the middle section of the U-shaped rod body 2. The extension direction of the end of the U-shaped rod body 2 is parallel to the extension direction of the main rod section of the U-shaped rod body 2. The two bent portions 7 are both located on the same side of the U-shaped rod body 2, and the position of the U-shaped rod body 2 near its end is in close contact with the main rod section of the U-shaped rod body 2.

[0047] 2. The component structure of the connecting component 4 is different. Specifically, the connecting component 4 is a limiting plate 8 provided on the bending portion 7. The limiting plate 8 is provided with two through holes 81 for the U-shaped rod 2 to pass through.

[0048] Combine Figure 2 As shown, the limiting plate 8 is located in the curved portion 7, and the end of the U-shaped rod body 2 is in close contact with the main rod section of the U-shaped rod body 2, which plays a good limiting role on the limiting plate 8, ensuring the limiting effect of the limiting plate 8 on the U-shaped rod body 2 and improving the stability of the connection between the U-shaped rod body 2 and the cell sheet 1.

[0049] Example 5

[0050] Combine Figure 2 and Figure 10 As shown, the only difference between this embodiment and embodiment 4 is that the two bent portions 7 are respectively located on both sides of the U-shaped rod body 2, and the U-shaped rod body 2 is in contact with the side wall of the limiting plate 8 near its end. The limiting plate 8 remains stable under the action of the two bent portions 7 located on both sides of the U-shaped rod body 2, so that the U-shaped rod body 2 and the cell sheet 1 are fixed.

[0051] Example 6

[0052] like Figure 11 and Figure 12 As shown, the only difference between this embodiment and embodiment 4 is that the two bent portions 7 are both located on the same side of the U-shaped rod body 2, and the end of the U-shaped rod body 2 abuts against the side of the limit plate 8 away from the limit ring 3. The end of the U-shaped rod body 2 has a good abutting effect on the limit plate 8, ensuring the stability of the limit plate 8 and the U-shaped rod body 2 during use.

[0053] Example 7

[0054] like Figure 1 As shown, the embodiment of the present application discloses a geocell, a cell sheet 1 and a geocell node connection structure. The cell sheet 1 is preferably made of polyester (PET). The geocell node connection structure in this embodiment is any one of the geocell node connection structures in Examples 1-6, which changes the connection method of adjacent cell sheets 1 of the geocell in the traditional technology such as welding, riveting or injection molding, and improves the tensile strength and stability of the geocell during use.

[0055] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
