The bottom of the support column 5 is fixedly connected to a bottom plate 6. The bottom plate 6 is made of an elastic material to further provide protection and improve the safety performance of the hanging net 2. An adjusting component 7 is provided on the outer side wall of the mounting frame 1. A connecting shaft 8 is rotatably provided on the adjusting component 7, and a fastening component 9 is fixed on the connecting shaft 8, which can be applied to cylindrical and square construction frames.

[0023] As Figure 3As shown in the figure, the adjusting component 7 includes a first threaded rod 12 and a threaded sleeve 10. The first threaded rod 12 is fixed on the outer side wall of the mounting frame 1. The threaded sleeve 10 is threadedly sleeved on the first threaded rod 12. Rotating the threaded sleeve 10 drives the fastening component 9 to move relatively, so as to adjust the fixed position.

[0024] As Figure 5 shown in the figure, the fastening component 9 includes a clamping plate 17 and a bottom support plate 16. The connecting shaft 8 is rotatably arranged at one end of the threaded sleeve 10. The other end of the connecting shaft 8 is fixedly connected with a connecting frame 13. The connecting frame 13 is U-shaped. A second threaded rod 14 is threadedly connected to the bottom wall of the connecting frame 13. The bottom support plate 16 is rotatably arranged at the top end of the second threaded rod 14. Third threaded rods 15 are symmetrically threadedly connected to the side walls of the connecting frame 13. The clamping plate 17 is rotatably arranged at one end of the third threaded rod 15. A clamping groove 18 is arranged in the clamping plate 17. A side turning block 19 is fixed at one end of the third threaded rod 15. A bottom turning block 11 is fixed at one end of the second threaded rod 14, which is convenient for rotating the third threaded rod 15 and the second threaded rod 14.

The arcs at the bottoms of the bottom support plate 16 and the clamping plate 17 jointly clamp the cylindrical construction frame, and the clamping plate 17 clamps the square construction frame.

[0025] During specific use, when installing the hanging net 2, first rotate the threaded sleeve 10 to make the connecting frame 13 move relatively, and align the connecting frame 13 with the position of the construction frame to be fixed. When the construction frame is cylindrical, rotate the connecting shaft 8 to make the connecting frame 13 rotate to the vertical state, place the cylindrical construction frame on the bottom support plate 16 inside the connecting frame 13, hold the clamping plate 17, rotate the side turning block 19 to drive the third threaded rod 15 to rotate, the third threaded rod 15 drives the clamping plate 17 to move, and the clamping plates 17 approach each other, pressing the bottom of the clamping plate 17 against the top wall of the cylindrical construction frame, rotate the bottom turning block 11 to drive the second threaded rod 14 to rotate, so that the bottom support plate 16 presses against the bottom of the cylindrical construction frame; when the construction frame is square, rotate the clamping plate 17 by 90° to align with the square construction frame, hold the clamping plate 17, rotate the side turning block 19 to drive the third threaded rod 15 to rotate, the third threaded rod 15 drives the clamping plate 17 to move, and the clamping plates 17 approach each other, clamping the square construction frame in the clamping groove 18, so as to install and fix the hanging net 2.

[0026] When the construction worker falls on the hanging net 2, the hanging net 2 itself provides the first buffer for the construction worker. As the hanging net 2 moves downward, it drives the fixed connecting plate 3 and the support column 5 to move downward, and the spring 4 is compressed. Under the reaction force of several springs 4, the impact force of the construction worker's fall is buffered, thus greatly avoiding the situation that the hanging net 2 is torn due to the impact force, and ensuring the personal health and safety of the construction worker. The bottom plate 6 provides further protection and improves the safety performance of the hanging net 2.

[0027] The above description is made for the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design, without creative efforts, structural modes and embodiments similar to the technical solution without departing from the gist of the creation of the present utility model, they shall fall within the protection scope of the present utility model.
