DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1: Please refer to Figures 1-4, A detachable protective net for building construction, including a protective net board 1. A reinforcing frame 3 is installed at the rear end of the protective net board 1. Installation grooves 16 are provided at both the upper and lower ends of the rear end of the protective net board 1, and mounting seats 6 are installed inside the installation grooves 16. Grooves 17 are provided inside the mounting seats 6. Left threaded rods 15 are movably installed on the right sides inside the grooves 17, and right threaded rods 18 are movably installed on the left sides inside the grooves 17. Moving seats 19 are movably arranged on the outer side walls of the left threaded rods 15 and the right threaded rods 18. Clamping blocks 20 are fixed at the front ends of the moving seats 19. Scaffold rods 5 are movably arranged inside the clamping blocks 20. Arc-shaped grooves 21 are provided on one side of each clamping block 20, and rubber blocks 22 are fixed inside the arc-shaped grooves 21. Second bevel gears 9 are installed on the right sides of the left threaded rods 15. First bevel gears 7 are meshed with the rear ends of the second bevel gears 9. Shafts 14 are fixed at the rear ends of the first bevel gears 7, and rotary handles 13 are installed at the rear ends of the shafts 14. The threads on the outer side walls of the left threaded rods 15 and the right threaded rods 18 are opposite. The left side of the right threaded rod 18 is fixedly connected to the right side of the left threaded rod 15, driving the clamping blocks 20 to move inward or outward together. The cross-section of the moving seat 19 is larger than that of the mounting seat 6. A sliding structure is formed between the moving seat 19 and the mounting seat 6, enabling the moving seat 19 to stably drive the clamping block 20 to move smoothly;

[0024] Specifically, as Figure 2 and Figure 3 shown, when installing this protective net at one end of the scaffold rod 5 for protection, rotate the rotary handle 13 to drive the first bevel gear 7 to rotate. The rotation of the first bevel gear 7 drives the second bevel gear 9 meshed at one end to rotate. The rotation of the second bevel gear 9 causes the connected left threaded rod 15 and right threaded rod 18 to rotate together. Since the threads of the left threaded rod 15 and the right threaded rod 18 are opposite, it drives the moving seat 19 to move inward together, driving the clamping block 20 to clamp on the outer side wall of the scaffold rod 5, thus installing this protective net board 1 at one end of the scaffold rod 5. When disassembling and installing later, reverse-rotate the rotary handle 13 to make the first bevel gear 7 rotate in the reverse direction. The reverse rotation of the first bevel gear 7 drives the second bevel gear 9 to rotate in the reverse direction. The reverse rotation of the first bevel gear 7 drives the left threaded rod 15 and the right threaded rod 18 to rotate in the reverse direction, and then the moving seat 19 can be driven to drive the clamping block 20 to move outward to open the clamping on the scaffold rod 5, so that this protective net board 1 can be easily removed without the aid of tools.

[0025] Embodiment 2: Upper holes 4 are provided on both sides of the top end of the protective net plate 1, and lower holes 10 are provided on both sides of the bottom end inside the protective net plate 1. A limiting clamping rod 2 is installed inside the upper hole 4 and the lower hole 10, and a circular groove 8 is provided at the top end inside the limiting clamping rod 2. There are four groups of upper holes 4 and lower holes 10, and the four groups of upper holes 4 and lower holes 10 are on the same vertical line. The cross-section of the limiting clamping rod 2 is smaller than the cross-sections of the upper hole 4 and the lower hole 10. A clamping structure is formed between the limiting clamping rod 2 and the upper hole 4 and the lower hole 10, so that different protective net plates 1 can be stably stacked together;

[0026] Specifically, as Figure 1 and Figure 2 shown, when different protective net plates 1 are stacked together, when the first group of protective net plates 1 and the second group of protective net plates 1 are stacked together, the limiting clamping rod 2 is inserted into the lower hole 10 at the bottom end of the first group of protective net plates 1 and the upper hole 4 at the upper end of the second group of protective net plates 1, so that the first group of protective net plates 1 and the second group of protective net plates 1 can be stably connected together for protection.

[0027] Embodiment 3: Adjusting seats 11 are fixed at the upper and lower ends of the front end of the protective net plate 1. Adjusting grooves 24 are provided inside the adjusting seats 11. Extension net plates 23 are movably provided inside the adjusting grooves 24. Fixing holes 25 are provided at the upper and lower ends inside the extension net plates 23. Fixing bolts 12 are movably provided inside the fixing holes 25. There are several fixing holes 25, and the several fixing holes 25 are evenly distributed at the upper and lower ends inside the extension net plates 23. The extension net plate 23 can be adjusted to different positions so that the protective net plate 1 can be used with different protective widths;

[0028] Specifically, as Figure 2 and Figure 4 shown, when adjusting the protective width of the protective net, after unscrewing the fixing bolt 12, pull the extension net plate 23 to one side to unfold it on one side of the protective net plate 1, and then screw the fixing bolt 12 into the corresponding fixing hole 25 to adjust the extension net plate 23 to a suitable position and adjust the protective net plate 1 to a suitable width for protective use.

[0029] Working principle: When the utility model is in use, obtain the protective net and then adjust the protective width of the protective net plate 1 according to the actual required protective width. During the adjustment, unscrew the fixing bolt 12 and then pull the extension net plate 23 to one side to make it unfold on one side of the protective net plate 1. Then, screw the fixing bolt 12 into the corresponding fixing hole 25 to adjust the extension net plate 23 to a suitable position and adjust the protective net plate 1. After adjusting the width, the protective net plate 1 can be attached to the outer wall of the scaffolding rod 5 so that it is clamped inside the clamping block 20. At this time, rotate the turning handle 13 to drive the first bevel gear 7 to rotate. The first bevel gear 7 drives the second bevel gear 9 meshed at one end to rotate. The rotation of the second bevel gear 9 causes the left threaded rod 15 and the right threaded rod 18 to rotate together. Since the threads of the left threaded rod 15 and the right threaded rod 18 are opposite, it drives the moving seat 19 to move inward together, driving the clamping block 20 to clamp on the outer wall of the scaffolding rod 5, thereby installing the protective net plate 1 at one end of the scaffolding rod 5. After the first group of protective net plates 1 is installed on the outer wall of the scaffolding rod 5, obtain the second group of protective net plates 1, stack them above the first group of protective net plates 1, and install them on the outer wall of the scaffolding rod 5. Then, the rear limit clamping rod 2 is inserted into the lower hole body 10 at the bottom end of the first group of protective net plates 1 and the upper hole body 4 at the upper end of the second group of protective net plates 1, so that the first group of protective net plates 1 and the second group of protective net plates 1 can be stably connected together for protection.

[0030] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
