[0027] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0028] See also Figure 1-8 The utility model provides a protective net for construction projects, which is used for protection in construction projects. Compared with the existing technology, multiple protective nets can be connected and used and their shapes can be adjusted according to the terrain requirements. Technical solution:

[0029] A protective net for construction projects includes a first column 1, a second column 2, and a protective net body 3 arranged between the first column 1 and the second column 2. A first plug rod 4 is arranged in the first column 1, and the top of the second column 2 is rotatably connected to a rotating block 18. The surface of the rotating block 18 is fixedly connected to an upper connecting rod 5. The upper surface of the upper connecting rod 5 is provided with an upper through hole that is compatible with the first plug rod 4. The upper connecting rod 5 is sleeved on the surface of the first plug rod 4 through the upper through hole to realize the connection and steering of the first column 1 and the second column 2.

[0030] Specifically, by sleeved on the first insertion rod 4, the upper connecting rod 5 is connected to the first insertion rod 4 and can rotate, and then the first column 1 is connected to the second column 2 and can turn, thereby achieving the effect of connecting and using multiple protective nets and adjusting their shapes according to terrain requirements.

[0031] In order to improve the stability after the first column 1 and the second column 2 are connected, a rotating ring 6 is rotatably connected to the surface of the second column 2, and a lower connecting rod 7 is fixedly connected to the surface of the rotating ring 6. The lower connecting rod 7 is provided with a lower through hole adapted to the first insertion rod 4. A fan-shaped groove 8 is provided on the surface of the first column 1, and the first insertion rod 4 is movably arranged in the first column 1 so as to move up and down and pass through the lower connecting rod 7.

[0032] Specifically, the lower connecting rod 7 is rotated and placed into the groove 8, and the first insertion rod 4 is moved downward so that the first insertion rod 4 is inserted into the lower connecting rod 7, so that the lower connecting rod 7 is connected to the first insertion rod 4 and can rotate, further improving the stability between the first column 1 and the second column 2.

[0033] A first cavity 9 is provided inside the first column 1, and the inner bottom wall of the first cavity 9 is rotatably connected to the first rotating tube 10. The surface of the first insertion rod 4 is slidably connected to the inner wall of the first rotating tube 10. A first through hole 11 for the passage of the first insertion rod 4 is opened in the inner bottom wall of the first cavity 9. The top end of the first column 1 is fixedly connected to the end cover 12. The top end of the first insertion rod 4 passes through the upper surface of the end cover 12, and there is damping friction between the first insertion rod 4 and the end cover 12.

[0034] A second cavity 13 is provided inside the second column 2, and a second rotating tube 14 is rotatably connected to the inner bottom wall of the second cavity 13, and a second insertion rod 15 is slidably connected to the inner wall of the second rotating tube 14. A second through hole 16 for the passage of the second insertion rod 15 is opened in the inner bottom wall of the second cavity 13, and the top end of the second insertion rod 15 passes through the upper surface of the rotating block 18, and there is damping friction between the second insertion rod 15 and the rotating block 18.

[0035] Both ends of the protective net body 3 are fixedly connected to the surfaces of the first rotating tube 10 and the second rotating tube 14 respectively.

[0036] Specifically, by providing a rotatable first insertion rod 4 and second insertion rod 15, the first rotating tube 10 and the second rotating tube 14 can be driven to rotate respectively when they rotate, thereby rolling up the protective net body 3, making it easier to carry the device.

[0037] In order to facilitate adjustment of the angle between the two protective nets, the bottom ends of the first column 1 and the second column 2 are rotatably connected to a walking assembly 17 .

[0038] The walking assembly 17 includes a mounting plate 171 rotatably connected to the bottom ends of the first column 1 and the second column 2, a mounting block 172 is fixedly connected to the lower surface of the mounting plate 171, a walking wheel 173 is rotatably connected to the side of the mounting block 172, and an opening 174 is provided on the upper surface of the mounting plate 171 that passes through the lower surface of the mounting block 172.

[0039] Specifically, by providing the walking wheels 173, the protective net can be easily moved, thereby facilitating the user to adjust the angle between the two protective nets. At the same time, the first insertion rod 4 and the second insertion rod 15 can be inserted into the ground after the adjustment is completed to achieve positioning.

[0040] Working principle: When the protective net for construction projects is used, the user first erects the first protective net, then presses the second insertion rod 15 downward to insert it into the ground, fixes the second column 2, and then pulls the first column 1 to unwind the protective net, and then puts the upper connecting rod 5 of the second protective net on the first insertion rod 4 of the first protective net, rotates the lower connecting rod 7 of the second protective net and puts it into the groove 8 of the first protective net, then moves the first insertion rod 4 of the first protective net downward so that the first insertion rod 4 is inserted into the lower connecting rod 7 of the second protective net, and continues to insert it into the ground, fixes the first column 1 of the first protective net, and connects the first protective net with the second protective net, and then rotates the second protective net with the cooperation of the walking component 17 as needed. When the angle between the first protective net and the second protective net is appropriate, the second insertion rod 15 of the second protective net is inserted into the ground, and the subsequent protective net casing is installed in the same way as above. Compared with the existing technology, multiple protective nets can be connected and used, and their shapes can be adjusted according to terrain requirements.
