Spring protection net

Abstract

The utility model provides a kind of spring protective net, which includes multiple rows of horizontal springs and multiple rows of longitudinal springs. In the same row of horizontal springs, the first hooks of the two adjacent horizontal springs are mutually hooked to form a horizontal elastic load chain. In the same row of longitudinal springs, the second hooks of the two adjacent longitudinal springs are mutually hooked to form a longitudinal elastic load chain. The multiple rows of horizontal springs and the multiple rows of longitudinal springs are arranged in a crisscross manner to form a net structure. The adjacent horizontal springs and longitudinal springs are mutually hooked to form dynamic interlocking nodes. When the local net surface bears impact load, the impact force is transmitted and dispersed along the horizontal elastic chain and the longitudinal elastic chain synchronously via the hook connection nodes, triggering the cooperative deformation of the entire net spring to absorb energy, effectively avoiding local structural failure caused by stress concentration, and significantly improving the impact stability and global buffer reliability of the protective net.

Description

Technical Field

[0001] This utility model relates to the field of protective netting structures, and in particular to a spring-loaded protective netting. Background Technology

[0002] In the field of impact protection, laminated structures of elastic materials are commonly used to achieve energy absorption. Existing technologies mostly rely on continuous buffer layers composed of polymer foams or rubber-based composites, which are then fixed to a rigid backing plate via bonding or hot pressing. Some solutions use woven fiber meshes to enhance the overall structural integrity, with fiber intersections forming fixed nodes through resin curing. Other solutions fill porous energy-absorbing materials within a metal mesh interlayer, relying on the material's own compression deformation to dissipate external impact energy.

[0003] However, when such structures are subjected to point impacts, the impact energy is difficult to effectively diffuse to the surrounding areas. The stress in the load-bearing center increases rapidly due to material deformation saturation, while the material in the peripheral areas remains in a low-strain state. This imbalance in stress distribution leads to two types of failure: permanent crushing of local materials or peeling of adhesive interfaces, ultimately resulting in a sharp drop in the buffering effectiveness of the protective system and loss of structural integrity. Utility Model Content

[0004] In view of the shortcomings mentioned above in the background technology, this utility model provides a spring protective net.

[0005] The present invention adopts the following technical solution:

[0006] A spring-loaded protective net, characterized in that the protective net comprises:

[0007] Multiple rows of transverse springs, each transverse spring having a first hook at both ends, with the first hooks of two adjacent transverse springs interlocking to form a connection.

[0008] Multiple rows of longitudinal springs, each of which has a second hook at both ends, and the second hooks of two adjacent longitudinal springs are connected to each other.

[0009] The multiple rows of transverse springs and the multiple rows of longitudinal springs are arranged in a crisscross pattern to form a mesh structure. The first hook of the transverse spring is connected to the second hook of the two adjacent longitudinal springs, and the second hook of the longitudinal spring is connected to the first hook of the two adjacent transverse springs.

[0010] In one possible implementation, the first or second hook located at the edge is connected to a mounting ring, which is used to connect to an external support structure.

[0011] In one possible implementation, the mounting ring is a spring buckle, which is fitted onto the side support rod of the frame when the support structure is a frame.

[0012] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: This utility model constructs a mesh structure by arranging multiple rows of transverse springs and multiple rows of longitudinal springs in a crisscross pattern. The first hook of the transverse spring and the second hook of the longitudinal spring are interlocked to form a dynamic interlocking node. When a local mesh surface is subjected to an impact load, the impact force is transmitted and dispersed synchronously along the transverse elastic chain and the longitudinal elastic chain through the hook connection node, triggering the coordinated deformation of all springs in the mesh to absorb energy. This effectively avoids local structural failure caused by stress concentration and significantly improves the impact resistance stability and overall buffer reliability of the protective mesh.

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0016] In this application, directional terms such as "upper" and "lower" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.

[0017] This utility model provides a spring-loaded protective net, as shown in the attached figure. Figure 1 and 2 As shown, the protective netting includes multiple rows of transverse springs 2 and multiple rows of longitudinal springs 3. Each transverse spring 2 has a first hook 21 at both ends, and each longitudinal spring 3 has a second hook 31 at both ends. In the same row of transverse springs 2, the first hooks 21 of adjacent transverse springs 2 interlock to form a transverse elastic load-bearing chain. Similarly, each longitudinal spring 3 has a second hook 31 at both ends, and in the same row of longitudinal springs 3, the second hooks 31 of adjacent longitudinal springs 3 interlock to form a longitudinal elastic load-bearing chain.

[0018] Referring to the attached diagram, multiple rows of transverse springs 2 and multiple rows of longitudinal springs 3 are arranged in a crisscross pattern to form a mesh matrix. The first hook 21 of the transverse spring 2 is interlocked with the second hook 31 of two adjacent perpendicular longitudinal springs 3, and the second hook 31 of the longitudinal springs 3 is interlocked with the first hook 21 of two adjacent perpendicular transverse springs 2. This forms a cross-interlocking connection structure. This connection structure allows the transverse springs 2 and longitudinal springs 3 to form a network of movable nodes with multi-directional degrees of freedom. The interlocking structure of the first hook 21 and the second hook 31 maintains the rigidity of the mechanical connection while allowing each spring unit to undergo coordinated deformation. When an external impact load is applied to the mesh, the interlocking nodes will synchronously disperse the concentrated stress along the transverse and longitudinal elastic chains, triggering the coordinated energy absorption behavior of the spring matrix. Through the extension and recovery characteristics of the transverse springs 2 and the longitudinal springs 3, multi-directional load transfer and buffering efficiency optimization are achieved, ultimately resulting in a synergistic improvement in impact resistance and structural reliability.

[0019] In addition, the protective net of this utility model can also be equipped with an installation ring 4. The installation ring 4 is used to connect the protective net of this utility model to an external support structure. Specifically, the installation ring 4 passes through the first hook 21 or the second hook 31 located at the edge of the protective net and the external support structure. In a preferred embodiment, the installation ring 4 adopts a spring buckle configuration. When the support structure is in the form of a frame 1, the spring buckle is directly sleeved on the outside of the support rod on the side of the frame 1, forming a circumferential constraint on the protective net. Further, when the support rod is equipped with a connection hole 101, the installation ring 4 can be inserted into the connection hole 101. This structure effectively transfers the boundary load of the protective net to the support system. While maintaining the degree of freedom of the connection between the first hook 21 and the second hook 31, it can enhance the overall anti-peeling ability of the protective net structure, greatly improve the boundary connection stability and installation adaptability of the protective net in a vibration environment, and ensure the complete realization of the buffer function in the system integration state.

[0020] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
