[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Combined with the attachedFigure 1 , 2 , 3. The utility model provides a detachable protective net for construction projects, which includes a net frame 1 and a connecting rod 2. The two sides of the net frame 1 are respectively slidably connected to the corresponding connecting rods 2. The lower end of the connecting rod 2 is fixedly connected with a holding rod 21, and the lower end of the holding rod 21 is fixedly connected with a fixing mechanism 3. The upper end of the connecting rod 2 is threadedly connected with a limiting member 4. The fixing mechanism 3 includes a fixing cone 31, a drilling rod 32, and a counterweight anchor 33. The counterweight anchor 33 is fixedly connected to the lower end of the holding rod 21, the drilling rod 32 is fixedly connected to the lower end of the counterweight anchor 33, and the fixing cone 31 is fixedly connected to the lower end of the drilling rod 32. When installing the detachable protective net, find the position where the protective net needs to be arranged. With the fixing cone 31 facing downwards, slowly rotate the holding rod 21 in the soil of the construction area. The holding rod 21 is of a polygonal structure and is sleeved with a number of friction pads 23 on the outside. The user can increase the friction between the palm and the holding rod 21 through the friction pads 23. The fixing cone 31 and the drilling rod 32 enter the soil in sequence. The outside of the drilling rod 32 is provided with drilling threads to facilitate the entry of the drilling rod 32. When the counterweight anchor 33 is in contact with the soil surface, the fixing of the connecting rod 2 is completed. Use the same method to fix the other connecting rod 2, and then slide the net frame 1 into the connecting rods 2 on both sides respectively, which effectively reduces the workload of on-site personnel and facilitates the subsequent development of construction projects;

[0022] One side of the connecting rod 2 is provided with a chute 22, and the net frame 1 is slidably connected in the chute 22. The upper end of the chute 22 is threadedly connected with the limiting member 4. The limiting member 4 includes a rotating plate 41 and a threaded rod 42. The threaded rod 42 is fixedly connected to one side of the rotating plate 41, and the threaded rod 42 is rotatably connected above the net frame 1 on the side of the chute 22. After the connecting rod 2 is fixed in the soil, slide the net frame 1 into the chute 22 from above the connecting rod 2, and then rotate the threaded rod 42 through the rotating plate 41 to make the threaded rod 42 rotate above the side of the net frame 1, thereby limiting the net frame 1 and preventing the net frame 1 from moving, ensuring the stability of the detachable protective net.

[0023] The working principle of this application is as follows:

[0024] When installing the detachable protective net, find the position where the protective net needs to be installed. With the fixing cone 31 facing downwards, slowly rotate the holding rod 21 in the soil of the construction area. The fixing cone 31 and the drilling rod 32 enter the soil in sequence. The outer side of the drilling rod 32 is provided with drilling threads to facilitate the entry of the drilling rod 32. When the counterweight anchor 33 is in contact with the soil plane, the fixing of the connecting rod 2 is completed. Use the same method to fix the other connecting rod 2. Then, slide the grid 1 from above the connecting rod 2 into the chute 22. Next, rotate the threaded rod 42 by rotating the rotating plate 41 so that the threaded rod 42 rotates above the side of the grid 1, thereby limiting the grid 1 and preventing the grid 1 from moving, ensuring the stability of the detachable protective net. In this patent, by setting the grid 1 and the connecting rod 2 to be slidably connected, it is convenient to disassemble and transport the protective net, the installation is simple, the workload of on-site personnel is effectively reduced, and it is convenient for the subsequent development of construction projects;

[0025] The above describes the present utility model and its implementation manners. Such description is not restrictive.
