A foldable scaffolding safety net

Abstract

This utility model relates to the field of scaffolding safety net technology and discloses a foldable scaffolding safety net, including an outer frame one and an outer frame two installed at the bottom of the outer frame one via hinges. It also includes two mesh panels welded to one side of the inner wall of the outer frame one and the outer frame two, respectively. A connecting mechanism is installed on the other side of the inner wall of the outer frame one. After the outer frame one and the outer frame two are unfolded, the connecting plate can pass through the locking plate and the through slot. The unfolded state of the outer frame one and the outer frame two can be restricted. Workers can then pass bolts and other connecting parts through the through slot and connect them to the scaffolding. Workers can also use steel wire in conjunction with the limiting mechanism to reinforce the stability of the safety net after installation. This solves the problem that some current safety nets use several bolts for fixing when unfolded, which is time-consuming, and the soft mesh panels wrapped around the frame surface are easily damaged during transportation and handling, affecting subsequent use.

Description

Technical Field

[0001] This utility model relates to the field of scaffolding safety net technology, specifically a foldable scaffolding safety net. Background Technology

[0002] Scaffolding safety nets, also known as climbing scaffold nets or external scaffolding safety nets, are a type of safety protection equipment used on construction sites. They are primarily composed of perforated metal plates with added frames, and are fixed to the building's external scaffolding using special connectors. They effectively prevent falling objects from heights and accidental falls by construction workers, providing crucial safety protection for construction projects.

[0003] A search revealed a Chinese patent document disclosing a foldable scaffolding safety net [Application No.: CN202320424771.8]. This foldable scaffolding safety net includes four side frames, which are connected end-to-end in a rotatable manner. The safety net has at least an unfolded state and a folded state. In the unfolded state, the four side frames form a square, and a mesh panel is provided within the square. In the folded state, the four side frames are located in the same plane and are parallel to each other. The four side frames form a square in the unfolded state.

[0004] The protective net disclosed in this patent can be folded for easy storage and transportation. However, after unfolding, workers need to tighten several bolts to fix the net in its unfolded state. This process is time-consuming and can affect the efficiency of the net. Furthermore, when the net is not in use, the soft mesh is directly wrapped around the surface of the frame, which is easily scratched during transportation and handling, thus affecting its normal use. Utility Model Content

[0005] The purpose of this invention is to provide a foldable scaffolding safety net to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foldable scaffolding safety net, comprising an outer frame one and an outer frame two installed at the bottom of the outer frame one via hinges, and further comprising:

[0007] Two mesh plates are welded to one side of the inner wall of outer frame one and outer frame two respectively. A connecting mechanism is installed on the other side of the inner wall of outer frame one, and a clamping plate is welded to the other side of the inner wall of outer frame two. Through slots are opened at the bottom of outer frame one and the top of outer frame two. Limiting mechanisms are installed on both sides of the surface of outer frame one and outer frame two. Slots and through slots are opened on the surface of outer frame one and outer frame two.

[0008] Preferably, the connecting mechanism includes guide rods, a lifting plate, and a connecting plate. There are two guide rods, which are respectively fixedly connected to both sides of an inner wall of the outer frame. The lifting plate is slidably sleeved on the surface of the guide rods. The connecting plate is fixedly connected to the bottom of the lifting plate. The surface of the connecting plate is in contact with the through groove and the inner wall of the clamping plate.

[0009] Preferably, the limiting mechanism includes a rotating shaft, a limiting plate, and a disc. There are several discs, which are rotatably connected to the surfaces of outer frame one and outer frame two, respectively. One end of the rotating shaft is fixedly connected to the surface of the disc, and the limiting plate is fixedly connected to the other end of the rotating shaft. A cylindrical groove is formed on the surface of the limiting plate.

[0010] Preferably, the surface of the limiting plate is in contact with the inner wall of the slot, and the length of the limiting plate is less than the length of the inner wall of the slot.

[0011] Preferably, the surface of the limiting plate is embedded with anti-slip pads, and there are several anti-slip pads, the surfaces of which are in contact with the surfaces of outer frame one and outer frame two respectively.

[0012] Preferably, an extension plate is fixedly connected to the surface of the disc, and arc-shaped plates are welded to the surfaces of both the outer frame one and the outer frame two. The surface of the extension plate is in contact with the surface of the arc-shaped plate, and the surface of the disc is in contact with the inner wall of the arc-shaped plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] When using this utility model, after the workers unfold the outer frame one and the outer frame two, the connecting plate can pass through the card plate and the through slot, thereby restricting the unfolded state of the outer frame one and the outer frame two. Afterwards, the workers can pass bolts and other connecting parts through the through slot and connect them to the scaffold. The workers can also use steel wire in conjunction with the limiting mechanism to strengthen the stability of the protective net after installation. This solves the problem that some current protective nets use several bolts for fixing when unfolded, which is time-consuming, and the soft mesh wrapped around the frame surface is easily damaged during transportation and handling, affecting subsequent use.

[0021] 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.

[0022] Please see Figure 1-5 As shown, a foldable scaffolding safety net includes an outer frame 1 and an outer frame 2 installed at the bottom of the outer frame 1 via hinges. A mesh plate 12 is welded to one side of the inner wall of both the outer frame 1 and the outer frame 2. A connecting mechanism 3 is installed on the other side of the inner wall of the outer frame 1, and a clamping plate 4 is welded to the other side of the inner wall of the outer frame 2. A through groove 5 is provided at the bottom of the outer frame 1 and the top of the outer frame 2. The through groove 5 facilitates the lifting and lowering movement of the connecting mechanism 3. Limiting mechanisms 6 are installed on both sides of the surface of the outer frame 1 and the outer frame 2. A slot 10 and a through groove 11 are provided on the surface of both the outer frame 1 and the outer frame 2. The limiting mechanism 6 cooperates with the slot 10 to restrict the state of the outer frame 1 and the outer frame 2 when the safety net is folded.

[0023] The connecting mechanism 3 includes guide rods 31, lifting plates 32, and connecting plates 33. There are two guide rods 31, which are fixedly connected to both sides of the inner wall of the outer frame 1. The lifting plate 32 is slidably sleeved on the surface of the guide rods 31. The connecting plate 33 is fixedly connected to the bottom of the lifting plate 32. The surface of the connecting plate 33 is in contact with the inner wall of the through groove 5 and the inner wall of the clamping plate 4. When the worker unfolds the protective net, the lifting plate 32 and the connecting plate 33 can descend under the action of gravity. The connecting plate 33 passes through the through groove 5 and the clamping plate 4 to restrict the state of the outer frame 1 and the outer frame 2 after unfolding. The length of the lifting plate 32 is less than the length of the inner wall of the outer frame 1, which makes it easier for the worker to move the lifting plate 32 so that the connecting plate 33 can pass through the clamping plate 4 and the through groove 5 more easily.

[0024] The limiting mechanism 6 includes a rotating shaft 61, a limiting plate 62, and several discs 63. These discs 63 are rotatably connected to the surfaces of outer frame 1 and outer frame 2, respectively. One end of the rotating shaft 61 is fixedly connected to the surface of the disc 63, and the limiting plate 62 is fixedly connected to the other end of the rotating shaft 61. The surface of the limiting plate 62 contacts the inner wall of the slot 10. The length of the limiting plate 62 is less than the length of the inner wall of the slot 10. When the operator folds the outer frame 1 and outer frame 2, the limiting plate 62 can smoothly pass through the slot 10. Afterward, the operator rotates the limiting plate 62... 2. To control the folded state of outer frame 1 and outer frame 2, the surface of the limiting plate 62 is embedded with anti-slip pads 7. There are several anti-slip pads 7, and the surfaces of the several anti-slip pads 7 are in contact with the surfaces of outer frame 1 and outer frame 2 respectively. After the rotating shaft 61 and the limiting plate 62 rotate, the state between the limiting plate 62 and outer frame 1 and outer frame 2 can be restricted through the cooperation of the anti-slip pads 7. The surface of the limiting plate 62 is provided with columnar grooves. Workers pass steel wires through the columnar grooves and connect them to the scaffolding to strengthen the stability of the protective net installed on the scaffolding surface.

[0025] An extension plate 8 is fixedly connected to the surface of the disc 63. Arc-shaped plates 9 are welded to the surfaces of the outer frame 1 and the outer frame 2. The surface of the extension plate 8 is in contact with the surface of the arc-shaped plate 9, and the surface of the disc 63 is in contact with the inner wall of the arc-shaped plate 9. When the operator rotates the limiting plate 62, the rotating shaft 61 can drive the disc 63 to rotate. At the same time, the extension plate 8 rotates accordingly. The arc-shaped plate 9 and the extension plate 8 cooperate to limit the range of rotation of the disc 63, thereby increasing the practicality of the limiting mechanism 6.

[0026] Working principle: When this protective net is not in use, it can be presented as... Figure 2 In the indicated state, the limiting plate 62 is rotated to restrict the position of the outer frame 1 and outer frame 2 after folding. Afterwards, the operator rotates the limiting plate 62 in the opposite direction and adjusts it to the indicated position. Figure 2 As shown in the diagram, the worker can then flip the outer frame 1 to unfold both outer frame 1 and outer frame 2. After unfolding, the lifting plate 32 and connecting plate 33 can pass through the clamping plate 4 and through slot 5 under the action of gravity, thus restricting the unfolded state of outer frame 1 and outer frame 2. The state of this protective net is as follows. Figure 1 As shown, workers can use bolts or other connectors to pass through the through slot 11 and connect it to the scaffold to install the protective net. At this time, the surface of the anti-slip pad 7 is in contact with the surface of the scaffold. Workers can use steel wire to pass through the cylindrical groove on the surface of the limiting plate 62 and connect it to the scaffold to further increase the stability of the protective net installed on the scaffold surface.
