By creating a physical barrier, it effectively prevents construction workers, tools, and building materials from accidentally falling, while also reducing the impact of construction on the surrounding environment, such as dust and noise pollution.

[0003] Chinese Patent Publication No. CN 212224707 U discloses a construction safety net with a support structure. In this technical solution, the strength of the entire safety net is improved by reinforcing the steel wire, and the safety net components are stably connected to the steel pipe at the installation position using support rod components and fixing components. However, this device relies on the support rods on both sides to be fixed to the ground for support, which is not stable enough. When subjected to external forces (such as wind, personnel collisions, etc.), it may tilt or even collapse, which cannot effectively prevent people from falling and objects from falling from heights, thereby increasing the safety risks at the construction site. Utility Model Content

[0004] This utility model provides a protective net with a stable support structure, which aims to solve the problem that relying on support rods on both sides to fix it on the ground for support is not stable enough and will cause it to tilt or even collapse when subjected to external forces (such as wind, collisions with people, etc.).

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a protective net with a stable support structure, including a support column 1, a receiving groove 2 is provided on the rear side of the support column 1, and a sealing plate 3 for preventing blockage of the receiving groove 2 is rotatably provided on the rear side of the support column 1.

[0020] The support column 1 itself has a built-in mounting component at the bottom, which ensures that it can be fixed to the ground or soil. This technology is existing technology and will not be described in detail here.

[0021] A fixing plate 6 is rotatably provided at the bottom of the receiving groove 2. A connecting cylinder 11 is rotatably provided at the top of the receiving groove 2 and inside the fixing plate 6. A support rod 12 is retractably provided at the bottom of the connecting cylinder 11. A groove 16 is provided on the fixing plate 6. A protrusion 13 that matches the groove 16 is fixedly connected to one end of the support rod 12. When the fixing plate 6 is rotated to a horizontal state, the protrusion 13 is inserted into the groove 16 to support the protective net by extending the support rod 12 and rotating the connecting cylinder 11.

[0022] When stored, the fixing plate 6 and the support rod 12 can be completely hidden in the receiving slot 2, reducing the space occupied.

[0023] In this embodiment, the fixing plate 6 can be manufactured separately for use on flat cement ground. Multiple mounting holes can be opened on the fixing plate 6 for fixing the fixing plate 6 to the flat cement ground, thereby improving the stability support of the protective net.

[0024] During production, the connecting cylinder 11, support rod 12 and protrusion 13 can be manufactured separately. The bottom of the protrusion 13 can be provided with ground nails or have recessed holes to fix the protrusion 13 separately in the soil, so as to ensure that it plays a supporting role for the protective net when used at the border.

[0025] Rotate the fixing plate 6 from its stored state (e.g., vertical) to its horizontal state to serve as a support base for the protective net. Pull out the support rod 12 to extend its length to the desired position, ensuring that the protrusion 13 is aligned with the groove 16 of the fixing plate 6. Rotate the connecting cylinder 11 to drive the support rod 12 to rotate synchronously, so that the protrusion 13 is embedded in the groove 16, forming a stable support structure.

[0026] Furthermore, the sealing plate 3 is connected to the support column 1 by a hinge. A first locking block 4 is provided in the middle of one side of the sealing plate 3, and a second locking block 5 adapted to the first locking block 4 is provided in one side of the support column 1. Both the first locking block 4 and the second locking block 5 have through holes in the middle, and a lock is inserted through the two through holes to fix them.

[0027] In this embodiment, when the sealing plate 3 is opened, it can be fixed by using a pin to prevent it from shaking randomly after opening, which would cause unnecessary impact on the support of the protective net.

[0028] The sealing plate 3 can be rotated from the closed state (covering the receiving groove 2) to the open state (exposing the receiving groove 2) via the hinge, or the reverse operation can be performed to close it.

[0029] When the sealing plate 3 is rotated to the closed position, the through holes of the first locking block 4 and the second locking block 5 are automatically aligned. The lock (such as a bolt) is inserted through the through hole of the first locking block 4 and through the through hole of the second locking block 5 to complete the physical fixation. When the sealing plate 3 needs to be opened, the lock is removed and the sealing plate 3 is rotated to the open state through the hinge.

[0030] Furthermore, the connecting cylinder 11 has two first positioning holes 14 in the middle, and the rear end surface of the support rod 12 has a first positioning hole 14. The connecting cylinder 11 can be fixed by inserting a fixing pin 15 into the first positioning hole 14.

[0031] In this embodiment, the support rod 12 is pulled out from the connecting cylinder 11 and aligned with the first positioning hole 14 on the outside. The fixing pin 15 is then inserted into the aligned first positioning hole 14 to complete the relative fixation of the connecting cylinder 11 and the support rod 12. After the fixing pin 15 is inserted, the connecting cylinder 11 can be rotated to finely adjust the angle of the support rod 12, ensuring that the protrusion 13 is accurately engaged in the groove 16 of the fixing plate 6.

[0032] Furthermore, a first rotating shaft 7 is rotatably provided at the bottom of the receiving groove 2, a first connecting sleeve 8 is fixedly connected to the surface of the first rotating shaft 7, and the fixing plate 6 is fixedly connected to the surface of the first connecting sleeve 8.

[0033] In this embodiment, ground nails can be installed at the bottom of the fixing plate 6 to ensure more stable contact with the ground.

[0034] By rotating the fixing plate 6, it can be switched from a stored state (such as vertical) to a horizontal state, serving as a support base for the protective net. The fixing plate 6 can rotate around the first rotation axis 7 to any angle to adapt to different terrains or support requirements.

[0035] Furthermore, a second rotating shaft 9 is rotatably provided at the top of the receiving groove 2 and located inside the fixing plate 6. A second connecting sleeve 10 is fixedly connected to the surface of the second rotating shaft 9, and the connecting cylinder 11 is fixedly connected to the surface of the second connecting sleeve 10.

[0036] In this embodiment, the pitch angle of the support rod 12 can be adjusted by rotating the connecting cylinder 11 to adapt to different terrains or support requirements.

[0037] Furthermore, the top of the support column 1 is provided with a second positioning hole 17, and the second rotating shaft 9 and the second connecting sleeve 10 are provided with a plurality of second positioning holes 17. The connecting cylinder 11 is fixed by inserting a positioning pin into the second positioning hole 17.

[0038] In this embodiment, after the protrusion 13 of the support rod 12 is inserted into the groove 16, the connecting cylinder 11 can be fixed by inserting the positioning pin into the second positioning hole 17, thus ensuring stability during support.

[0039] The working principle and usage process of this utility model are as follows: After the utility model is installed, the fixing plate 6 is rotated from the storage state (such as vertical) to the horizontal state, serving as the support base for the protective net. The support rod 12 is pulled out to extend its length to the required position, ensuring that the protrusion 13 is aligned with the groove 16 of the fixing plate 6. The connecting cylinder 11 is rotated to drive the support rod 12 to rotate synchronously, so that the protrusion 13 is embedded in the groove 16. Finally, the positioning pin is inserted into the second positioning hole 17 to fix it, forming a stable support structure.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
