[0032] In addition, there are also node connectors in the form of buckling to realize the connection of the node of the geocell. Although the node connection structure formed by such buckling form node connector has good mechanical properties, the buckling part itself usually needs to be manufactured by injection molding through a special mold, and two buckling parts are usually "male and female buckles" (such as the first buckling part and the second buckling part in the patent document CN217203974U, the two buckling parts have different structures and are buckled with each other during use), which requires the design of two sets of molds for separate production, resulting in high cost.

[0033] The utility model provides a node connecting piece of geocell, the node connecting piece is the node connecting piece of buckle form, specifically is two same structure buckles and forms the node connecting structure of mutual buckling, and the node connecting structure formed has good mechanical properties, and only needs a set of mould to complete the production and manufacture of buckling piece.

[0034] Embodiment 1:

[0035] As Figures 1 to 4 And Figure 6 、 Figure 7 The utility model provides a node connecting piece of geocell, the node connecting piece includes locking piece and two buckles 2;

[0036] The buckle 2 includes the base body 21, and the limiting unit is fixedly arranged above the base body 21;

[0037] Two buckles 2 can be buckled to each other along the height direction of base body 21, and after buckling, the limiting unit of two buckles 2 has a cooperation gap in the height direction, and the cooperation gap is used for accommodating the geocell belt body at the node;

[0038] The locking piece is used for locking two buckles 2 in the buckling state.

[0039] Specifically, the limiting unit includes a first protruding part 22 extending along the height direction of the base body 21, the first protruding part 22 includes an arc-shaped first protruding section 221 and an arc-shaped first recess section 222, and a first transition section 223 is connected between the first protruding section 221 and the first recess section 222;

[0040] In the case where two buckles 2 are buckled to each other, the first protruding section 221 of one buckle 2 cooperates with the first recess section 222 of the other buckle 2, and the cooperation gap exists between the first protruding parts 22 of two buckles 2.

[0041] More specifically, the limiting unit further includes a second protruding part 23 extending along the height direction of the base body 21, and the first protruding part 22 and the second protruding part 23 are adjacent in the length direction of the base body 21;

[0042] The second protruding part 23 includes an arc-shaped second protruding section 231 and an arc-shaped second recess section 232, and a second transition section 233 is connected between the second protruding section 231 and the second recess section 232; the first protruding section 221 and the second recess section 232 are located on the same side of the base body 21, and the first recess section 222 and the second protruding section 231 are located on the same side of the base body 21;

[0043] In the case that the two fasteners 2 are fastened to each other, the second protruding section 231 of one fastener 2 is matched with the second recessed section 232 of the other fastener 2; the matching gap exists between the first protruding sections 22 of the two fasteners 2, and exists between the second protruding sections 23 of the two fasteners 2.

[0044] The plurality of limiting units are arrayed along the length direction of the base body 21, and any two adjacent limiting units are adjacent in the length direction of the base body 21. Preferably, the number of the limiting units is 3 to 5.

[0045] Accordingly, the node connector of the geocell provided by the embodiment is fastened to each other by two fasteners 2 which are structurally identical, and then locked by the locking member, thereby forming the node of the geocell, which has the characteristic of good mechanical properties (it should be understood that, in the case that the two fasteners 2 are fastened to each other, the first protruding section 22 of one fastener 2 is abutted with the second protruding section 23 of the other fastener 2 in the length direction of the base body 21, forming a structure of mutual engagement, which limits the relative movement of the two fasteners 2 in the length direction of the base body 21, and then the locking member only needs to limit the relative movement of the two fasteners 2 in the thickness direction and the width direction of the base body 21, in the case that the node is stressed, the strength of the fastener 2 itself and the strength of the locking member jointly determine the strength of the node), and only one set of mold is used for the production of the fastener 2, which greatly reduces the mold cost required for the production of the node connector, and improves the economic benefit.

[0046] Embodiment 2:

[0047] The embodiment is based on Embodiment 1, and the difference is that, in the embodiment:

[0048] The limiting unit further comprises a clamping portion 24 extending in the height direction of the base body 21, and the clamping portion 24 is arranged on both sides of the first protruding section 22 in the width direction of the base body 21 and on both sides of the second protruding section 23 in the width direction of the base body 21.

[0049] Accordingly, in the case that the two fasteners 2 are fastened to each other, the geocell belt body is clamped between the two opposite clamping portions 24, so that the belt body is in a flat state (please refer to Figure 4 、 Figure 6 、 Figure 7, the two strip bodies are in uniform contact with the corresponding clamping portions 24 (referring to the situation that the strip bodies are in flat contact with the clamping portions 24) under the condition that the node is subjected to a pulling force (in the technical field of geocell, the node is subjected to a pulling force refers to the situation that the two ends of one strip body at the node are subjected to a first pulling force, and the two ends of the other strip body at the node are subjected to a second pulling force, the first pulling force and the second pulling force are in opposite directions and coincide with the thickness direction of the strip body at the node), and the fastener 2 can uniformly bear the pulling force, so that the fastener 2 is not easy to be damaged by the pulling force.

[0050] Preferably, a groove 29 is formed from the bottom of the base body 21 towards the first protruding section 221 and the second protruding section 231.

[0051] Therefore, the wall thickness of the fastener 2 can be made uniform, and since the fastener 2 is usually produced by injection molding, the density, mass and mechanical properties of each part of the fastener 2 with uniform wall thickness are consistent, and deformation such as warping of the fastener 2 during the cooling process after injection molding is avoided, ensuring the quality of the fastener 2; in addition, the groove 29 can also make the connection between the filler in each cell and the fastener 2 stronger after the geocell is laid (the filler enters the groove 29), thereby facilitating the prevention of the geocell from separating from the filler (in the width direction of the strip body) during use.

[0052] Embodiment 3:

[0053] As shown in Figures 1 to 8 , this embodiment is based on embodiment 1, and the difference is that in this embodiment:

[0054] The first mounting plate 25 and the second mounting plate 26 are respectively fixedly arranged at the two ends of the base body 21 in the length direction;

[0055] The first mounting plate 25 and the first protruding section 221 are located on the same side of the base body 21, and the second mounting plate 26 and the second protruding section 231 are located on the same side of the base body 21;

[0056] A first through hole 27 and a second through hole 28 are formed in the fastener 2, the first through hole 27 penetrates the first mounting plate 25 and the first protruding section 221 along the length direction of the base body 21, and the second through hole 28 penetrates the second mounting plate 26 and the second protruding section 231 along the length direction of the base body 21;

[0057] The locking member includes two plug rod portions 31;

[0058] In the case that the two fasteners 2 are buckled towards each other, for any fastener 2, the first through hole 27 of the fastener 2 and the second through hole 28 of the other fastener 2 are coaxial, and the two insertion rod portions 31 are respectively inserted into the first through hole 27 and the second through hole 28 of the fastener 2.

[0059] Thus, the two insertion rod portions 31 can limit the relative movement of the two buckled fasteners 2 in the thickness direction and the width direction of the base body 21, so as to reliably lock the two fasteners 2 in the buckled state, and the structure is simple and easy to manufacture; obviously, in order to ensure that the insertion rod portions 31 have sufficient strength and corrosion resistance, the insertion rod portions 31 are preferably made of stainless steel.

[0060] Preferably, a first ring groove 251 is formed in the first through hole 27 of the first mounting plate 25 and the second through hole 28 of the second mounting plate 26, and an elastic collar 32 is arranged in the first ring groove 251.

[0061] The inner diameter of the elastic collar 32 is smaller than the outer diameter of the insertion rod portion 31.

[0062] It should be understood that the elastic collar 32 can be a metal ring with a cutout, and correspondingly, the elastic collar 32 is arranged in an insert with a ring groove structure, and then the insert is embedded into the fastener 2 in the injection molding stage (embedding the insert into the plastic part in the injection molding stage is a conventional technical means in the injection molding field, which will not be described here), or the elastic collar 32 can be an elastic ring made of plastic, and correspondingly, the elastic collar 32 can be pressed into the first ring groove 251 after the fastener 2 is produced.

[0063] Accordingly, during the process of inserting the insertion rod portion 31 into the first through hole 27 or the second through hole 28, the elastic collar 32 is expanded, and after the insertion rod portion 31 is inserted, the elastic collar 32 can ensure that the insertion rod portion 31 does not come out (due to the influence of external forces such as jolting, throwing, etc. during the transportation, transportation, and laying of the earthwork geocell, the insertion rod portion 31 may slide out of the first through hole 27 or the second through hole 28 in the opposite direction of insertion; the expanded elastic collar 32 is wrapped on the outer peripheral surface of the insertion rod portion 31 (as shown in Figure 5 、 Figure 8 ), because the end surface of the elastic collar 32 and the first ring groove 251 abuts, the elastic collar 32 wrapped on the outer peripheral surface of the insertion rod portion 31 exerts a static friction force on the insertion rod portion 31, which can effectively limit the relative movement of the insertion rod portion 31 and the elastic collar 32, thereby preventing the insertion rod portion 31 from coming out), so as to ensure the locking effect of the locking member on the two fasteners 2 in the buckled state.

[0064] More preferably, a second ring groove 311 is formed on the insertion rod portion 31.

[0065] When the two buckles 2 are buckled to each other and the two insertion rod portions 31 are respectively inserted into the first through hole 27 and the second through hole 28 of one of the buckles 2, the elastic sleeve ring 32 is located in the second ring groove 311.

[0066] Thus, after the insertion rod portion 31 is inserted into the first through hole 27 or the second through hole 28, the elastic sleeve ring 32 is located in the second ring groove 311 (as shown in Figure 8 At this time, the elastic sleeve ring 32 that is expanded can be retracted to recover the inner diameter, thus the elastic sleeve ring 32 and the end face of the first ring groove 251 abut, and the end face of the second ring groove 311 abuts, and the effect of the elastic sleeve ring 32 preventing the insertion rod portion 31 from being pulled out is better.

[0067] The above specific embodiments further specifically describe the purpose, technical scheme and beneficial effects of the utility model, and it should be understood that the above description is only a specific embodiment of the utility model and is not used to limit the protection scope of the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
