Description

Technical Field

[0001] This utility model provides a stainless steel fall arrest net, and particularly relates to a stainless steel fall arrest net with a snap-fit ​​connection. Background Technology

[0002] Fall protection nets are safety protection devices used in high-altitude operations, construction, and various high-altitude areas. Their main function is to prevent people, tools, or other objects from falling from heights by setting up physical barriers, thereby reducing the risk of safety accidents. They are widely used in scenarios such as the perimeter of scaffolding, elevator shafts, the outside of balconies, and both sides of bridges. Their core function is to form a protective area based on their own structural strength, thereby blocking and buffering falling objects.

[0003] Current fall protection nets typically consist of a support frame, a net body, and connectors. The support frame is usually made of steel pipes or angle steel, fixed by welding or bolts. The net body is usually made of ordinary steel wire mesh or nylon mesh. Connectors are mainly made of wire, cable ties, or bolts. During installation, the edges of the net body need to be manually tied to the support frame point by point with wire, or bolts are used to fix the net body to the frame through the edges. This structure has obvious shortcomings: wire tying is not only cumbersome and time-consuming, but also prone to rust and breakage after long-term use. Bolt connections require tools to tighten each bolt individually, resulting in low assembly and disassembly efficiency. At the same time, the existing connectors lack a limiting structure for the fit between the connectors and the frame, which can easily lead to loosening and displacement of the net body. In addition, the connection position between the net body and the frame is fixed, making it difficult to flexibly adjust the installation position of the net body inside or outside the frame according to actual protection needs. Overall, the adaptability and ease of maintenance are poor. Utility Model Content

[0004] In order to solve the above problems, this application provides a snap-fit ​​stainless steel fall arrest net, which solves the problems of cumbersome disassembly and assembly, low efficiency, easy loosening and displacement of the connection, inflexible installation position, and easy corrosion and failure of the connectors in existing fall arrest nets.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a stainless steel fall protection net with a snap-fit ​​connection, comprising:

[0006] The supporting frame consists of several vertically arranged uprights and several horizontal beams that connect the uprights, forming a three-dimensional frame structure.

[0007] A stainless steel fall arresting net, in the form of a mesh, covers one or both sides of the supporting frame;

[0008] Buckles are used to connect the stainless steel fall protection net to the support frame;

[0009] The edges of the stainless steel fall protection net are engaged with the uprights and / or beams of the support frame via the buckles, enabling quick assembly and disassembly.

[0010] Preferably, the buckle has a U-shaped structure.

[0011] The open end of the U-shaped structure is fitted with a clip onto the upright or crossbeam.

[0012] The closed end of the U-shaped structure is fixedly connected to the edge of the stainless steel fall protection net.

[0013] Preferably, the stainless steel fall arresting net is woven from crisscrossing stainless steel wires to form a regular grid; the intersections of the grid are connected to the closed ends of the buckles.

[0014] Preferably, the surfaces of the uprights and crossbeams of the support frame are provided with slots or protrusions for the buckles, and the slots / protrusions engage and limit the opening end of the U-shaped buckle to prevent the buckle from sliding.

[0015] Preferably, the stainless steel fall arrestor net can be selectively installed on the inner or outer side of the support frame via clips.

[0016] When installed on the inside, the clips snap into the uprights / beams from the inside of the frame;

[0017] When installed on the outside, the clips snap into the uprights / beams from the outside of the frame.

[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0019] When using this utility model of a snap-fit ​​stainless steel fall arrest net, first connect the closed end of the U-shaped snap-fit ​​to the edge of the stainless steel fall arrest net body, which is woven into a regular grid of intersecting stainless steel wires (fitting connection at the grid intersections). Then, use the snap-fit ​​open end to fit the buckle on the uprights or beams of the support frame. The buckle and beams of the support frame have grooves or protrusions on their surfaces, which engage with the open end of the U-shaped snap-fit ​​to limit and prevent slippage. At the same time, the stainless steel fall arrest net body can be selectively installed from the inside (snap-fit ​​from the inside of the frame) or the outside (snap-fit ​​from the outside of the frame) of the support frame through the snap-fit. With the quick snap-fit ​​characteristics of the snap-fit, the mesh-like stainless steel fall arrest net body is quickly fixed on the three-dimensional support frame composed of vertical uprights and horizontal beams, forming a fall arrest barrier, realizing convenient disassembly and assembly of the fall arrest net and stable protection.

[0025] 1. Support frame; 2. Stainless steel safety net; 3. Buckle. Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] like Figure 1 and Figure 2 As shown, a snap-fit ​​stainless steel fall arrest net includes a three-dimensional support frame 1 composed of several vertical poles and horizontal beams, a stainless steel fall arrest net body 2 that is mesh-like and covers one or both sides of the support frame 1, and snap-fit ​​3 for connecting the two; the snap-fit ​​3 has a U-shaped structure, with its open end adapted to fit onto the poles or beams, and its closed end fixedly connected to the edge of the stainless steel fall arrest net body 2, so that the edge of the stainless steel fall arrest net body 2 is engaged with the poles and / or beams of the support frame 1 through the snap-fit ​​3, achieving quick assembly and disassembly.

[0030] In this embodiment, the buckle 3 has a U-shaped structure. Its open end fits onto the upright or crossbeam, and its closed end is fixedly connected to the edge of the stainless steel fall arrest net 2. This allows the edge of the stainless steel fall arrest net 2 to engage with the upright and / or crossbeam of the support frame 1 via the buckle 3, enabling quick assembly and disassembly. In this embodiment, the support frame 1 forms a stable three-dimensional structure through the combination of vertical uprights and horizontal crossbeams, providing basic support for the entire fall arrest device. The uprights remain vertical, and the crossbeams connect the uprights laterally, ensuring the overall strength of the frame. The stainless steel fall arrest net 2 is mesh-like and effectively prevents falls. It covers one or both sides of the support frame 1, and the coverage position can be selected according to actual fall arrest requirements. The U-shaped design of the buckle 3 allows its open end to precisely engage with the upright or crossbeam of the support frame 1, while its closed end is fixed to the edge of the stainless steel fall arrest net 2. This structure eliminates the need for complicated operations when connecting the two. From an implementation perspective, during installation, simply align the open end of the buckle 3 with the upright or crossbeam and snap it in to complete the connection between the stainless steel fall arrest net 2 and the support frame 1. Disassembly is done by reversing the operation, greatly improving installation and disassembly efficiency. From an innovative perspective, the U-shaped structure of the buckle 3 enables quick snapping, changing the cumbersome nature of traditional connection methods. The three-dimensional structure of the support frame 1 ensures the stability of the device. The mesh design of the stainless steel fall arrest net 2 satisfies the fall arrest function while reducing the overall weight. The cooperation of each component enables the device to achieve convenient installation and maintenance while providing good fall arrest effect, solving the problems of troublesome installation and difficult disassembly of traditional fall arrest nets. The support frame 1 provides stable support for the device, ensuring that it is not easily deformed when subjected to external forces. The stainless steel fall arrest net 2 directly plays the role of fall arrest, blocking falling objects. The buckle 3 is the key to achieving quick connection and disassembly, making the use of the entire device more flexible and efficient.

[0031] like Figure 2 and Figure 3 As shown, the stainless steel fall arrest net 2 is woven from crisscrossing stainless steel wires into a regular grid, with the closed ends of the connecting buckles 3 corresponding to the grid intersections; the surfaces of the uprights and crossbeams of the support frame 1 are provided with slots or protrusions that fit the buckles 3, which engage with the open ends of the U-shaped buckles 3 to limit their movement and prevent the buckles 3 from sliding; and the stainless steel fall arrest net 2 can be selectively installed on the inner or outer side of the support frame 1 via the buckles 3. When installed on the inner side, the buckles 3 engage with the uprights / crossbeams from the inner side of the frame, and when installed on the outer side, the buckles 3 engage with the uprights / crossbeams from the outer side of the frame.

[0032] In this implementation plan, during the actual use of this device, existing tools such as electric drills and screwdrivers are required to pre-install and fix the uprights and crossbeams of the support frame 1. The uprights and crossbeams can be made of 304 stainless steel, which has good corrosion resistance and strength. During installation, a measuring tape may be needed to measure the dimensions of the support frame 1 to ensure that the stainless steel fall protection net 2 matches the specifications. The stainless steel fall protection net 2 can be woven from 316 stainless steel wire with a diameter of 2mm, which is suitable for use in humid environments. The buckle 3 can be made of high-strength nylon or 45# steel. When the buckle 3 is made of metal, rubber gaskets may be needed to cover the contact area between the buckle 3 and the support frame 1 to prevent wear caused by rigid contact. At the same time, when fixing the support frame 1 to the wall or other base, existing fasteners such as expansion bolts and embedded parts are required. After drilling holes in the base with an electric drill, the expansion bolts are driven in to securely install the support frame 1, ensuring that the entire fall protection net system can function safely and reliably.

[0033] Specifically, in the implementation of this solution, the uprights and crossbeams of the support frame 1 can be pre-connected and fixed using existing welding processes (such as arc welding), or detachable assembly can be achieved using flanges and bolts. Welding is suitable for fixed scenarios, while flange connections facilitate later adjustments to the frame dimensions. The stainless steel fall protection net 2 can be woven using existing plain weave or twill weave processes. During the weaving process, a tension regulator is used to maintain uniform wire tension and ensure consistent mesh size (e.g., 10cm × 10cm). The production of the buckles 3 can utilize existing injection molding technology (for nylon materials). Alternatively, stamping technology (for metal materials) can be used, followed by deburring to ensure smooth installation. During installation, if the support frame 1 needs to be temporarily fixed, existing scaffolding or hoisting equipment can be used for positioning assistance. After the frame is leveled (using a level), it can be tightened to the base with expansion bolts. In later maintenance, existing ultrasonic flaw detection technology can be used to check for cracks in the welded parts of the support frame 1, and calipers can be used to measure whether the opening size of the buckle 3 meets the standard. If the buckle 3 is found to be worn, it can be quickly replaced with existing replacement tools (such as buckle screwdrivers) to ensure the continuous and stable operation of the entire fall protection system.

[0034] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
