Description

Technical Field

[0001] This utility model relates to the field of protective equipment technology, and in particular to an active protective net fixing device. Background Technology

[0002] Active safety nets are widely used in transportation, construction, and industry, primarily to protect personnel, facilities, and equipment from external impacts or hazardous factors. They are suitable for the safety protection of critical facilities such as highways, bridges, tunnels, and airports. In the transportation sector, active safety nets effectively prevent falling objects, road collapses, or other unexpected accidents, ensuring driving safety. In the construction and industrial sectors, they prevent falling objects from heights and construction site accidents, protecting the lives of construction workers. Furthermore, the elasticity and energy absorption capacity of active safety nets can mitigate impacts, thereby reducing damage and improving safety levels.

[0003] The fixing devices for active safety nets are primarily used to ensure the stability and effectiveness of the netting. Their function is to securely fix the netting to the ground, walls, or other supporting structures, preventing displacement or detachment when subjected to external impacts. Common fixing methods include using steel columns, concrete bases, and ground anchors, employing appropriate fastening devices and tension systems to ensure the netting's tension and balance. During installation, the design is typically tailored to the terrain and environmental conditions to ensure the netting can function to its maximum potential in the event of an impact, protecting personnel and facilities.

[0004] However, existing active protective netting connection methods typically rely on complex fixing devices and extensive manual operation, resulting in cumbersome installation and dismantling processes, relatively poor stability, and susceptibility to external environmental influences. Secondly, the structure of most existing protective nets relies on a single layer of mesh. This design may not effectively disperse pressure under strong impacts, easily leading to localized deformation or damage, thus affecting the overall protective effect. Furthermore, traditional protective nets have limited room for improvement in impact absorption and load-bearing capacity.

[0005] To address the above issues, an active protective net fixing device is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an active protective net fixing device, which aims to solve the problems of cumbersome installation and disassembly and poor stability of existing active protective net fixing devices.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an active protective net fixing device, comprising a protective net body, wherein the protective net body comprises a front net, a grid plate, a rear net and a fixing frame, and a connecting mechanism is provided at the end of the fixing frame;

[0008] The connecting mechanism includes a rotating drum and a connecting column. The rotating drum is rotatably connected to the middle of the connecting column. Multiple sliding grooves are provided around the outer side of the connecting column, and a snap-fit ​​component is provided inside the sliding groove.

[0009] As a further description of the above technical solution:

[0010] The snap-fit ​​assembly includes a limiting plate, one end of which is fixedly connected to a pin, and the other end of which is fixedly connected to a pull rope. A tension spring is sleeved on the outside of the pin.

[0011] As a further description of the above technical solution:

[0012] The end of the pull rope away from the limiting plate is fixedly connected to the inner wall of the rotating drum.

[0013] As a further description of the above technical solution:

[0014] The limiting plate is slidably connected inside the slide groove, and the end of the pin passes through the interior of the connecting column.

[0015] As a further description of the above technical solution:

[0016] One end of the tension spring is fixedly connected to the inner wall of the slide groove, and the other end of the tension spring is fixedly connected to the outer side of the limiting plate.

[0017] As a further description of the above technical solution:

[0018] One end of the connecting post is inserted into the end of the fixed frame, and the other end of the connecting post has an inner groove. The end of the other fixed frame is inserted into the inner groove, and the pin is inserted into the inside of the fixed frame.

[0019] As a further description of the above technical solution:

[0020] Multiple cable ties are provided between the front mesh, the grid plate, and the rear mesh.

[0021] As a further description of the above technical solution:

[0022] Anchor rods are installed at the diagonal corners of the fixed frame, and the mesh diameter of the grid plate is smaller than that of the front and rear meshes.

[0023] This utility model has the following beneficial effects:

[0024] 1. This utility model, through its simple structural design, allows for the rapid fixing of two protective nets in predetermined positions without the need for complex tools, ensuring the stability of the overall protective system. It effectively solves the problems of cumbersome and unstable connection methods in traditional protective netting systems. This not only improves the installation efficiency of the protective netting but also facilitates subsequent disassembly and maintenance, saving time and costs, and greatly enhancing work efficiency and safety at the construction site.

[0025] 2. In this utility model, an additional layer of grid mesh is added to the protective netting, and the netting is sandwiched between two layers of protective netting, which enhances its impact absorption capacity and stability. This not only strengthens the overall strength of the protective netting but also effectively disperses external impact forces, making the mesh of the protective netting more stable, effectively improving the load-bearing capacity and deformation resistance of the netting surface, thereby improving the overall protective effect and service life.

[0031] 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.

[0032] Reference Figure 1 - Figure 2This utility model provides an embodiment of an active protective net fixing device, mainly comprising a protective net body 1, which is composed of a front net 11, a grid plate 12, a rear net 13, and a fixing frame 14. The front net 11, grid plate 12, and rear net 13 are connected by multiple cable ties 2 to ensure a stable connection between each layer of the net. To enhance the stability of the overall structure, anchor rods 3 are installed at the diagonals of the fixing frame 14. The anchor rods 3 are firmly connected to the ground through a fixing device, ensuring the stability of the protective net body 1 when subjected to external impact. The mesh size of the grid plate 12 is designed to be smaller than that of the front net 11 and the rear net 13. This design allows the grid plate 12 to effectively prevent smaller objects from penetrating the protective net, while also improving the net's ability to disperse impacts. A connecting mechanism 4 is provided at the end of the fixing frame 14. This connecting mechanism 4 is designed to quickly and stably connect multiple protective net units together, has good disassembly performance, and is convenient for installation and maintenance.

[0033] Reference Figure 2 - Figure 3 The connecting mechanism 4 includes a rotating cylinder 401 and a connecting column 402. The rotating cylinder 401 is rotatably connected to the middle of the connecting column 402. Multiple sliding grooves 403 are formed around the outer side of the connecting column 402. A snap-fit ​​assembly is installed inside each sliding groove 403 to facilitate quick connection and disassembly between two protective net units, improving overall installation efficiency. The snap-fit ​​assembly includes a limiting plate 404, which is slidably connected inside the sliding groove 403 and can move within a specific range. A pin 406 is fixedly connected to one end of the limiting plate 404. The end of the pin 406 penetrates the interior of the connecting column 402, achieving a reliable connection with the fixing frame 14 and enhancing the stability of the overall structure. A pull rope 405 is fixedly connected to the other end of the limiting plate 404. A tension spring 407 is sleeved on the outside of the pin 406. One end of the tension spring 407 is fixedly connected to the inner wall of the slide groove 403, and the other end is fixedly connected to the outside of the limiting plate 404, providing elastic support so that the pin 406 can remain locked in the normal state, improving the reliability of the connection. The end of the pull rope 405 away from the limiting plate 404 is fixedly connected to the inner wall of the rotating drum 401. By rotating the rotating drum 401, the pull rope 405 can be driven, thereby pulling the limiting plate 404 and releasing the pin 406 from the fixed state. After releasing the rotating drum 401, the pin 406 is relocked under the action of the tension spring 407. One end of the connecting post 402 is inserted into the end of the fixed frame 14. The other end of the connecting post 402 has an inner groove, so that the end of the other fixed frame 14 is inserted into the inner groove, ensuring that the two protective nets can be stably connected. Meanwhile, the pin 406 is inserted into the inside of the fixed frame 14 to connect the two protective net units. While ensuring the stability of the protective net structure, it improves its impact resistance and enables it to maintain good protective performance in complex environments.

[0034] Working principle: When connecting two protective net units, first insert one end of the fixed frame 14 into the inner groove of one end of the connecting post 402. At this time, the pin 406 is locked under the action of the tension spring 407, and its end passes through the connecting post 402 and is inserted into the fixed frame 14, thus completing the connection. After the connection is completed, the front net 11, grid plate 12 and rear net 13 of the protective net body 1 are fixed by the cable tie 2 and supported by the fixed frame 14 as a whole. At the same time, the anchor rod 3 is anchored to the ground by the fixing device to maintain the stability of the protective net. When the protective net needs to be disassembled, rotate the rotating drum 401 to tighten the pull rope 405, so that the limiting plate 404 slides along the slide groove 403 and pulls the pin 406 out of the fixed frame 14, releasing the locked state and allowing the fixed frame 14 to be separated from the connecting post 402. After releasing the rotating drum 401, the tension spring 407 returns to its original position, and the pin 406 returns to its original position, ready for the next connection operation.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
