[0029] The embodiments of the utility model are described in detail below, examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be explained as the limitation of the utility model.

[0030] As shown in Figures 1 to 3 the embodiment of the utility model provides a rope net fixing buckle for fixing the first rope body 100 and the second rope body 200, and the type of the first rope body 100 and the second rope body 200 includes but is not limited to steel wire rope, for the steel wire rope such high hardness and strength rope body, the buckle has enough clamping force and wear resistance to ensure that it is fixed firmly, and the rope body will not be loose or damaged in the use process.

[0031] The buckle is used for fixing the first rope body 100 and the second rope body 200 intersecting in the extending direction, so that the buckle can play a good connection and stabilization role in the rope net structure, the buckle can effectively fix the intersection, prevent the rope body from being displaced or loosened under stress, and thus ensure the stability of the entire rope net.

[0032] The buckle comprises a first part 10 and a second part 20 which can be separately matched, so that the buckle is more convenient to install and disassemble, can quickly fix or release the rope body, and greatly improves the work efficiency.

[0033] The first part 10 has a first inner surface 11 and a first outer surface 12, and the first inner surface 11 and the first outer surface 12 are located on opposite sides of the first part 10. The first part 10 is preferably a metal sheet, has high strength, durability and processability, and can be in the shape of a regular shape such as a circle, a square, a rhombus or an irregular shape, so that the buckle can adapt to different application scenarios and installation spaces, which are not limited here.

[0034] As shown in Figure 1 and Figure 4 The first inner surface 11 is provided with a protruding column fixing part 13 and a first limiting part 14. The protruding column fixing part 13 can be provided with a plurality of protruding column fixing parts 13 which are dispersedly arranged on the first part 10, can be dispersedly stressed, and can avoid local stress concentration, so as to improve the overall strength and reliability of the buckle. The number and distribution of the protruding column fixing part 13 can be determined according to the shape, size and actual demand of the first part 10, which are not limited here.

[0035] The first rope body 100 is limited by the first limiting part 14, and the first limiting part 14 is used for limiting the radial movement of the first rope body 100, so as to ensure that the first rope body 100 remains stable in the buckle and will not be loosened or displaced due to external force. The first limiting part 14 can be adaptively changed according to the diameter and material of the first rope body 100, so as to ensure that it can closely fit the first rope body 100 and will not cause excessive wear to the first rope body 100.

[0036] The second part 20 is arranged opposite to the first part 10, and the shape and size of the second part 20 can be the same as those of the first part 10, so that the two parts can be well matched together to form a stable fixing structure.

[0037] The second part 20 has a second inner surface 21 and a second outer surface 22, the second inner surface 21 is opposite to the second outer surface 22, and the second inner surface 21 is provided with a second limiting part 23, and the second rope body 200 is limited by the second limiting part 23. The second limiting part 23 is used to limit the radial movement of the second rope body 200, and can ensure that the first rope body 100 and the second rope body 200 are firmly fixed at the intersection point and will not be loosened or displaced due to external force. The second limiting part 23 can be adaptively changed according to the diameter and material of the second rope body 200, so as to ensure that it can closely fit the second rope body 200, and at the same time will not cause excessive wear to the second rope body 200.

[0038] As shown in Figure 1 and Figure 5 The second part 20 is provided with a fixing hole 24, the number and size of the fixing hole 24 correspond to the number and size of the convex column fixing part 13, and the convex column fixing part 13 extends and forms a fixed fit with the fixing hole 24. When the first part 10 and the second part 20 are matched, the convex column fixing part 13 extends and forms a fixed fit with the fixing hole 24, which ensures that the first part 10 and the second part 20 are tightly connected and will not be easily separated.

[0039] Before the buckle is assembled with the first rope body 100 and the second rope body 200, the first part 10 and the second part 20 are arranged opposite to each other, and the first rope body 100 and the second rope body 200 are arranged in cross between the first part 10 and the second part 20. The buckle can effectively fix two different direction rope bodies and form a stable intersection point.

[0040] When the buckle starts to be assembled, the convex column fixing part 13 of the first part 10 is opposite to the fixing hole 24 of the second part 20, the first rope body 100 is limited in the first limiting part 14 of the first part 10, and the second rope body 200 is limited in the second limiting part 23 of the second part 20. This double limiting design can ensure that the rope body will not be displaced during assembly, thereby ensuring the accuracy and reliability of assembly.

[0041] The protruding column fixing portion 13 of the first part 10 is fixed by preferably adopting riveting after passing through the fixing hole 24 of the second part 20, and the protruding column fixing portion 13 is deformed by applying pressure, so as to realize firm connection of the first part 10 and the second part 20. The riveting connection provides high connection strength, and ensures that the first part 10 and the second part 20 will not relatively deviate in use. The connection point formed by riveting is very firm, and can effectively cope with various changes in external environment, such as vibration and impact. Thus, the fixing firmness of the first part 10 and the second part 20 is improved, the first part 10 and the second part 20 will not relatively deviate when coping with changes in external environment, and the first rope body 100 and the second rope body 200 are also firmly fixed in the buckle and will not loosen or shift due to external force.

[0042] In a feasible implementation manner, as shown in Figure 1 and Figure 3 , before riveting, the protruding column fixing portion 13 is a cylindrical structure, which is formed by stamping the first part 10. After the protruding column fixing portion 13 passes through the fixing hole 24 and undergoes a riveting process, its form changes. Specifically, the protruding column fixing portion 13 includes a main column body 131 and a folded body 132. The main column body 131 is a cylindrical structure, which plays a supporting and positioning role, ensuring stable connection between the first part 10 and the second part 20. The folded body 132 is formed by riveting the cylindrical structure by a riveting mechanism, increasing the contact area and friction between the first part 10 and the second part 20, thereby improving the fixing firmness. Through deformation of the folded body 132, the two parts are tightly fixed together, which can effectively cope with various changes in external environment, such as vibration and impact.

[0043] As shown in Figure 3 , the main column body 131 and the folded body 132 each have a first end and a second end. The first end of the main column body 131 is connected with the first inner surface 11. When the first part 10 and the second part 20 are assembled, the main column body 131 extends through the fixing hole 24, and the first inner surface 11 and the second inner surface 21 are attached. The first end of the folded body 132 is connected with the second end of the main column body 131, and the second end of the folded body 132 extends along the radial direction of the main column body 131 and is attached with the second outer surface 22. The inner surface of the folded body 132 and the first inner surface 11 jointly clamp and fix the second part 20. Through the clamping action of the main column body 131 and the folded body 132, the first part 10 and the second part 20 can be tightly connected after assembly and will not relatively deviate. The first rope body 100 and the second rope body 200 are firmly fixed in the buckle and will not loosen or shift due to external force, thereby providing strong guarantee for safety and reliability of the rope net.

[0044] Furthermore, the main column 131 has a through cavity 133 extending along the axial direction. A reinforcing member 30 is embedded in the through cavity 133. Before the protruding column fixing part 13 is riveted, the through cavity 133 already exists in the cylindrical protruding column fixing part 13. During the riveting process of the riveting mechanism, the reinforcing member 30 is inserted into the protruding column fixing part 13 from the top opening of the through cavity 133. During the forming process of the protruding column fixing part 13, the reinforcing member 30 is embedded in the main column 131. This embedding method is simple and efficient, and the installation of the reinforcing member 30 can be completed simultaneously during the riveting process, thereby improving production efficiency.

[0045] The reinforcing member 30 is usually made of high-strength materials, such as steel, aluminum alloy or other high-strength composite materials, which can effectively enhance the tensile, compressive and shear resistance of the main column 131, not only improving the structural strength of the main column 131, but also enhancing the overall fastening reliability of the buckle.

[0046] In one feasible implementation, refer to Figure 6 As shown, the reinforcing member 30 includes a main body 31 and a guide 32. The outer contour surface of the main body 31 is adapted to the inner contour surface of the cavity 133, ensuring that the main body 31 can fit tightly against the inner wall of the cavity 133, thereby providing stable support and reinforcement. When the cross-section of the cavity 133 is circular, the cross-section of the main body 31 is also circular, which helps to distribute stress evenly and improve structural strength.

[0047] The guide portion 32 has a first end and a second end. The first end of the guide portion 32 is connected to the main body portion 31. The guide portion 32 and the main body portion 31 are preferably integrally formed. The outer surface of the guide portion 32 gradually tapers linearly from the first end to the second end. The guide portion 32 is preferably conical, and its outer surface is a guide slope. The conical design of the guide portion 32 plays a guiding role during the insertion process, allowing the reinforcing member 30 to smoothly enter the through cavity 133, reducing the alignment difficulty during assembly and improving assembly efficiency. After the reinforcing member 30 is inserted into the through cavity 133, the contact area between the guide portion 32 and the inner wall of the through cavity 133 gradually increases, forming a self-locking effect, effectively preventing the reinforcing member 30 from loosening due to vibration or impact during use, and improving the reliability of the latch.

[0048] In the embodiments provided by this utility model, the first limiting part 14 is a first limiting groove recessed on the first inner surface 11. When assembling the first split part 10 and the first rope 100, the first limiting part 14 is aligned with the first rope 100 and snapped in. The extension direction of the first rope 100 is consistent with the extension direction of the first limiting part 14. The first rope 100 is at least partially snapped into the first limiting part 14. The radial movement of the first rope 100 is blocked by the inner wall of the first limiting part 14. The contact between the first rope 100 and the inner wall surface of the first limiting part 14 is a surface contact with a large contact area, thereby providing a large friction force for the first rope 100, limiting the displacement of the first rope 100, and ensuring its stability within the buckle.

[0049] The second limiting part 23 is a second limiting groove recessed on the second inner surface 21. When assembling the second part 20 and the second rope 200, the second rope 200 is aligned with the second limiting part 23 and inserted into it. The extension direction of the second rope 200 is consistent with the extension direction of the second limiting part 23. The second rope 200 is at least partially inserted into the second limiting part 23. The radial movement of the second rope 200 is blocked by the inner wall of the second limiting part 23. The contact between the second rope 200 and the inner wall surface of the second limiting part 23 is a surface contact with a large contact area, thereby providing a large frictional force for the second rope 200 and restricting the displacement of the second rope 200.

[0050] In one feasible implementation, refer to Figures 1 to 5 As shown, the groove surfaces of the first and / or second limiting grooves are arc-shaped. The arc-shaped grooves better conform to the surface of the first rope 100 or the second rope 200, increasing the contact area and providing greater friction. This effectively restricts rope displacement and ensures its stability within the buckle. When the first rope 100 or the second rope 200 is subjected to external force, regardless of the direction in which it moves, the arc-shaped grooves provide a counteracting force, keeping the first rope 100 or the second rope 200 in its initial position. Even under complex stress conditions, it will not loosen or shift.

[0051] In another feasible embodiment, the groove surface of the first limiting groove and / or the second limiting groove includes a first groove surface and a second groove surface. The first groove surface and the second groove surface are symmetrically arranged along a preset reference surface. The first groove surface and the second groove surface intersect the preset reference surface at an incline. The symmetrical arrangement of the first groove surface and the second groove surface ensures uniform force on the groove body, so that the rope body can maintain balance and stability in the groove. The symmetrical structure of the groove body is not only aesthetically pleasing, but also effectively disperses stress and reduces local stress concentration.

[0052] Preferably, the first groove surface and the second groove surface together form a V-shaped groove structure, which has a good self-locking function. When the rope is subjected to external force, the inclined surfaces of the V-shaped groove can provide a reverse pressing force, further limiting the displacement of the rope. No matter which direction the rope moves, the two inclined surfaces of the V-shaped groove can give the rope a pressing force, ensuring that the rope remains in the initial position. The V-shaped groove can also adapt to ropes of different diameters, improving the versatility and adaptability of the buckle, so that it can be applied to various types of ropes.

[0053] In the embodiments provided by the utility model, a preset included angle is formed between the extension direction of the first limiting part 14 and the extension direction of the second limiting part 23, and the preset included angle can be determined according to the fixing needs of the rope net. The flexibility makes the buckle adapt to the crossing of ropes of various angles, thereby improving the versatility and applicability of the buckle. The extension directions of the first limiting part 14 and the second limiting part 23 have a certain included angle, which can limit the movement of the buckle and prevent the buckle from being displaced due to external force, thereby ensuring the overall stability of the rope net.

[0054] Preferably, the preset included angle is 90 degrees, which is suitable for most vertically crossed rope net structures. However, those skilled in the art can know that, according to actual needs, the preset included angle can also be set to 45 degrees, 60 degrees or other angles, which are not limited herein.

[0055] Referring to FIGS. 1-3, Figure 4 and Figure 5 As shown, a plurality of reinforcing ribs 15 are arranged in the first limiting groove and / or the second limiting groove. The reinforcing ribs 15 can significantly increase the contact area and friction force between the limiting groove and the rope. The rope can be effectively prevented from slipping when subjected to force, thereby ensuring the stability of the rope in the buckle. The plurality of reinforcing ribs 15 are sequentially and spacedly arranged along the axis direction of the first limiting groove and / or the second limiting groove, thereby dispersing the stress generated when the rope is subjected to force, avoiding stress concentration, reducing rope wear or buckle damage caused by excessive local stress, and thereby prolonging the service life of the buckle and the rope.

[0056] The above embodiments shown in the drawings illustrate the structure, features and effects of the utility model. The above description is only a preferred embodiment of the utility model, but the utility model is not limited by the drawings. Any changes or modifications made in accordance with the concept of the utility model, or equivalent embodiments with equivalent changes, shall be within the scope of protection of the utility model.
