[0002] Protective canopies are structures used to protect people or equipment passing below during construction, effectively preventing accidental falling objects from injuring people or equipment below. Current protective canopy construction typically requires multiple columns to support the main structure. This structure occupies space beneath the canopy, affecting the normal passage of pedestrians or equipment. Furthermore, it necessitates the connection of multiple vertical or horizontal members, resulting in a large workload and low construction efficiency. Utility Model Content
[0003] The purpose of this utility model is to provide a foldable external cantilever protective canopy connection and fixing device, which can solve the technical problems of existing protective canopy structures affecting traffic and low construction efficiency, simplify the construction steps, reduce the occupation of the space below, and greatly improve the smoothness of traffic and the efficiency of construction.
[0004] To achieve the above objectives, this utility model employs the following technical solution: A foldable, cantilevered protective canopy connection and fixing device includes a protective canopy support plate and a vertically arranged fixing plate. The bottom of the protective canopy support plate has multiple protective canopy frame rods. Both the upper and lower ends of the fixing plate have connecting grooves. One side of the fixing plate has a receiving groove for use with the protective canopy support plate. The upper and lower ends of the receiving groove are respectively rotatably connected to an upper connecting rod and a lower connecting rod. The end of the upper connecting rod is rotatably connected to the protective canopy support plate, and the end of the lower connecting rod is rotatably connected to a side connecting rod. The side connecting rod is parallel to the upper connecting rod, and its bottom end is rotatably connected to the protective canopy support plate. The top end of the side connecting rod is rotatably connected to a top connecting rod, which is parallel to the protective canopy support plate and rotatably connected to the upper connecting rod. The protective canopy support plate has a limiting part. When the protective canopy support plate rotates to a horizontal position, the side of the upper connecting rod contacts the limiting part. The bottom of the protective canopy support plate has multiple connecting fasteners for use with the protective canopy frame rods.
[0005] Furthermore, the top of the protective canopy support plate is provided with a groove, and the ends of the upper connecting rod and the side connecting rod are rotatably connected in the groove.
[0006] Furthermore, the limiting part is disposed on the side wall at one end of the groove.
[0007] Furthermore, the connecting fastener is provided with a socket, and the protective canopy pole is simultaneously and movably inserted into the sockets of multiple connecting fasteners.
[0008] Furthermore, multiple safety net hanging rings are provided on both the fixing plate and the protective canopy pole.
[0009] Furthermore, a steel wire rope is provided at the end of the protective canopy pole away from the connecting fastener.
[0010] Furthermore, an upper support component and a lower support component are movably inserted into the connecting grooves at the upper and lower ends of the fixed plate, respectively.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The protective canopy support plate of this utility model is connected to the fixed plate through the upper connecting rod, lower connecting rod, side connecting rod, and top connecting rod, providing support for the protective canopy support plate. The fixed plate is fixed to the ground or building through the connecting grooves at the upper and lower ends. Multiple horizontal protective canopy frame rods are set at the bottom of the protective canopy support plate, thus forming an external cantilever type protective canopy structure. This structure allows the protective canopy structure to be constructed by simply fixing the fixed plate, moving the protective canopy support plate to a horizontal position, and connecting the multiple horizontal protective canopy frame rods to the bottom of the protective canopy support plate. This ensures that the space below the protective canopy support plate is not occupied, greatly improving the smoothness of passage and greatly simplifying the construction steps. Only the fixed plate needs to be fixed, which greatly improves the overall construction efficiency of the protective canopy structure. 2. One side of the fixed plate is provided with a receiving groove for use with the protective shed support plate. The end of the upper connecting rod is rotatably connected to the protective shed support plate. The side connecting rod is arranged parallel to the upper connecting rod, and the bottom end of the side connecting rod is rotatably connected to the protective shed support plate. The top connecting rod is arranged parallel to the protective shed support plate, and the top connecting rod is rotatably connected to the upper connecting rod. The protective shed support plate is provided with a limiting part. When the protective shed support plate is rotated to the horizontal position, the side of the upper connecting rod contacts the limiting part. This structure allows the protective shed support plate to be folded and stored in the receiving groove on one side of the fixed plate, making the overall structure easy to move and install. When the protective shed support plate is rotated to the horizontal position, the contact between the limiting part and the upper connecting rod maintains the horizontal state of the protective shed support plate, improving the stability of the device during use. The overall structure can be used directly after unfolding, greatly saving on-site construction time and improving the efficiency of device installation and ease of use. Attached Figure Description

[0016] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.
[0017] Reference Figure 1 and Figure 2This utility model describes a foldable, cantilevered protective canopy connection and fixing device. The main structure includes a protective canopy support plate 1 and a vertically arranged fixing plate 2. The protective canopy support plate 1 is horizontally arranged, serving as the support structure for the canopy roof. The fixing plate 2 is vertically arranged, serving as the vertical support structure. The bottom of the protective canopy support plate 1 has multiple protective canopy frame rods 3, which extend laterally outwards, increasing the coverage area of the protective canopy. Steel plates are laid on the multiple protective canopy frame rods 3 to form the roof of the protective canopy. Both the upper and lower ends of the fixing plate 2 have connecting grooves 4 for connecting with fixing components, thereby fixing the top and bottom of the fixing plate 2 to the building and the ground. One side of the fixing plate 2 has a matching anti-corrosion... The protective canopy support plate 1 uses a receiving groove 5, which is recessed inward from one side of the fixed plate 2. The protective canopy support plate 1 can be folded and stored in the receiving groove 5, so that the entire device can be disassembled and stored for easy movement and transportation. The upper and lower ends of the receiving groove 5 are respectively rotatably connected to an upper connecting rod 6 and a lower connecting rod 7 by a pin or hinge. The bottom end of the upper connecting rod 6 is rotatably connected to the protective canopy support plate 1 by a pin or hinge. The top end of the lower connecting rod 7 is rotatably connected to a side connecting rod 8 by a pin or hinge. The side connecting rod 8 is arranged parallel to the upper connecting rod 6, and the bottom end of the side connecting rod 8 is rotatably connected to the protective canopy support plate 1 by a pin or hinge. A position on the protective canopy support plate 1 between the upper connecting rod 6 and the side connecting rod 8 is formed. The bottom connecting rod and the top connecting rod 8 are rotatably connected to the top connecting rod 9 via a pin or hinge. The top connecting rod 9 is parallel to the protective canopy support plate 1, and specifically, the top connecting rod 9 is parallel to the bottom connecting rod. The top connecting rod 9 and the upper connecting rod 6 are rotatably connected via a pin or hinge. This structure allows the top connecting rod 9, the bottom connecting rod, the upper connecting rod 6, and the side connecting rod 8 located between the top connecting rod 9 and the bottom connecting rod to form a parallelogram. This allows the protective canopy support plate 1 to be flipped and folded upwards. After flipping and folding, the parallelogram folds into a straight line, and the flipped and folded protective canopy support plate 1 is vertically stored in the receiving groove 5. This makes the device easy to move and transport after storage, greatly improving the convenience of movement and transportation. The protective canopy support plate 1 is easy to use and can be deployed immediately without the need for welding between multiple connecting parts, greatly improving the overall construction efficiency and ease of use. A limiting part 10 is fixed to the protective canopy support plate 1 by welding or bolts. When the protective canopy support plate 1 rotates to a horizontal position, the side of the upper connecting rod 6 contacts the limiting part 10. During the rotation and deployment of the protective canopy support plate 1, the upper connecting rod 6 rotates relative to the protective canopy support plate 1. When the protective canopy support plate 1 rotates to a horizontal position, the side of the upper connecting rod 6 contacts the limiting part 10, causing the limiting part 10 to block the relative rotation of the upper connecting rod 6, thus preventing the protective canopy support plate 1 from continuing to rotate and maintaining a horizontal state, improving the stability of the protective canopy support plate 1 during use.This makes the deployment and use of the device more convenient, and the absence of supporting columns obstructing the lower part of the deployed protective canopy support plate 1 ensures smooth passage below. The bottom of the protective canopy support plate 1 is equipped with multiple connecting fasteners 11 that work with the protective canopy frame poles 3. These fasteners 11 are block-shaped metal structures used to connect the protective canopy support plate 1 and the protective canopy frame poles 3, enabling rapid construction of the canopy roof and further improving the construction efficiency of the protective canopy structure.
[0018] Preferred, refer to Figure 3 The protective canopy support plate 1 has a groove 12 on its top. The groove 12 is recessed downward from the top of the protective canopy support plate 1 and extends through both the left and right ends of the protective canopy support plate 1. The ends of the upper connecting rod 6 and the side connecting rod 8 are rotatably connected in the groove 12 by a pin or hinge. With this structure, when the protective canopy support plate 1 is rotated and stored in the receiving slot 5, the upper connecting rod 6 and the side connecting rod 8 can be rotated and stored in the groove 12, thereby making the overall structure occupy less space after storage and making it easier to store in the receiving slot 5, further improving the convenience of storage of this device.
[0019] Preferably, the limiting part 10 is fixed to the side wall of one end of the groove 12 by welding or bolting. This structure ensures that the upper connecting rod 6 will not contact the limiting part 10 at the end during the rotation and unfolding of the protective shed support plate 1 to a horizontal state, making the unfolding process of the protective shed support plate 1 smoother. Until the protective shed support plate 1 is unfolded to a horizontal state, the side of the upper connecting rod 6 contacts the limiting part 10, preventing the upper connecting rod 6 from continuing to rotate relative to the protective shed support plate 1. This prevents the unfolded protective shed support plate 1 from continuing to rotate downward, thus maintaining a horizontal unfolded state and improving the convenience of unfolding and using this device.
[0020] Preferably, the connecting fastener 11 is provided with a through insertion hole 13, and the protective canopy frame rod 3 is simultaneously movably inserted into the insertion holes 13 of multiple connecting fasteners 11. Specifically, a limiting protrusion is provided on the protective canopy frame rod 3. After the protective canopy frame rod 3 is inserted into the insertion hole 13, the limiting protrusion contacts the connecting fastener 11 at the edge, so that the protective canopy frame rod 3 cannot be inserted further inward, thereby making the structure after insertion and connection more stable and further improving the firmness of the roof structure of the formed protective canopy.
[0021] Preferably, multiple safety net hanging rings 14 are fixed to the fixing plate 2 and the protective canopy frame pole 3 by welding or bolting. The safety net hanging rings 14 are used to fix the safety net, so that another safety net can be connected above the protective canopy, which further improves the protective effect of the protective canopy structure.
[0022] Preferably, the end of the protective canopy pole 3 away from the connecting fastener 11 is fixed with a steel wire rope 15 by bolts, and the other end of the steel wire rope 15 is fixed to the building by anchor bolts. The end of the protective canopy pole 3 away from the connecting fastener 11 is a suspended structure. The steel wire rope 15 is used to pull the suspended end, thereby making the formed cantilever structure more solid and further improving the stability of the protective canopy.
[0023] Preferably, an upper support member 16 and a lower support member 17 are movably inserted into the connecting grooves 4 at the upper and lower ends of the fixing plate 2, respectively. Preferably, both are T-shaped. The upper support member 16 is fixed to the building by welding or bolts, and the lower support member 17 is fixed to the ground by welding or bolts. This allows for quick connection between the two members after they are fixed, improving the convenience of fixing the fixing plate 2 and further improving the efficiency and convenience of construction.
[0024] Working Principle: The protective canopy support plate 1 of this utility model is connected to the fixed plate 2 via the upper connecting rod 6, lower connecting rod 7, side connecting rod 8, and top connecting rod 9, providing support for the protective canopy support plate 1. The fixed plate 2 is fixed to the ground or building via the connecting grooves 4 at both ends. Multiple horizontal protective canopy frame rods 3 are set at the bottom of the protective canopy support plate 1, thus forming an externally cantilevered protective canopy structure. This structure allows the protective canopy structure to be constructed by simply fixing the fixed plate 2, moving the protective canopy support plate 1 to a horizontal position, and connecting the multiple horizontal protective canopy frame rods 3 to the bottom of the protective canopy support plate 1. This ensures that the space below the protective canopy support plate 1 is not occupied, greatly improving the smoothness of passage and simplifying the construction steps. Only the fixed plate 2 needs to be fixed, greatly improving the overall construction efficiency of the protective canopy structure. One side of the fixed plate 2 is equipped with a tool for use with the protective canopy support plate 1. The receiving groove 5, the end of the upper connecting rod 6 is rotatably connected to the protective shed support plate 1, the side connecting rod 8 is arranged parallel to the upper connecting rod 6, the bottom end of the side connecting rod 8 is rotatably connected to the protective shed support plate 1, the top connecting rod 9 is arranged parallel to the protective shed support plate 1, and the top connecting rod 9 is rotatably connected to the upper connecting rod 6. The protective shed support plate 1 is provided with a limiting part 10. When the protective shed support plate 1 is rotated to the horizontal position, the side of the upper connecting rod 6 contacts the limiting part 10. This structure allows the protective shed support plate 1 to be flipped and folded into the receiving groove 5 on one side of the fixed plate 2, thereby making the overall structure easy to move and install. When the protective shed support plate 1 is rotated to the horizontal position, the contact between the limiting part 10 and the upper connecting rod 6 is used to maintain the horizontal state of the protective shed support plate 1, improving the stability of the device during use. This allows the overall structure to be used directly after unfolding, greatly saving on-site construction time and improving the efficiency of device installation and ease of use.
