[0024] The rotating shaft 3 is provided with a first opening for the rotating shaft 3 to pass through on each flange plate 2. When two adjacent protective meshes are connected, the rotating shaft 3 passes through all the flange plates 2 of the adjacent protective bars at the same time, so that the two adjacent protective meshes can rotate around the rotating shaft 3. Stopping members for stopping the flange plates 2 are detachably installed at both ends of the rotating shaft 3.

[0025] As a preferred implementation, Figures 1-2 As shown, the blocking member includes a first sleeve 4 and a first connecting plate 5 fixed to the end of the first sleeve 4. The outer diameter of the first sleeve 4 is not greater than the aperture of the first opening, and the inner diameter of the first sleeve 4 is not less than the outer diameter of the rotating shaft 3, so that the first sleeve 4 can pass through the flange plate 2 and be sleeved on the end of the rotating shaft 3. The area of ​​the first connecting plate 5 is greater than the hole area of ​​the first opening, so as to play a blocking role. The first connecting plate 5 is used to connect with an external structure, such as the ground, floor surface, etc.

[0026] Preferably, the inner diameter of the first sleeve 4 is equal to the outer diameter of the rotating shaft 3, and the surfaces of both are rough, which increases the friction force when the first sleeve 4 is connected to the rotating shaft 3, so that the first sleeve 4 and the rotating shaft 3 are firmly connected.

[0027] As a preferred implementation, Figure 1 , Figure 3As shown, the blocking member further includes a second sleeve 7 and a second connecting plate 8 fixed to the end of the second sleeve 7. The second connecting plate 8 is provided with a second opening for the rotation shaft 3 to pass through. The outer diameter of the second sleeve 7 is not greater than the aperture of the first opening, and the inner diameter of the second sleeve 7 is not less than the outer diameter of the rotation shaft 3, so that the first sleeve 4 can pass through the flange plate 2 and be sleeved on the outside of the rotation shaft 3. The area of ​​the second connecting plate 8 is greater than the hole area of ​​the first opening, so that the second connecting plate 8 can pass through the second opening and pass through the rotation shaft 3 and be blocked on the outside of the flange plate 2, thereby playing a blocking role.

[0028] As a preferred implementation, the protection rod 1 is made of square steel.

The first sleeve 4, the cushion block 6 and the first connecting plate 5 are connected by welding. The cushion block 6 can raise the height of the protective mesh to prevent the protective mesh from rubbing against the ground when rotating.

[0031] As a preferred embodiment, a third opening is formed on the first connecting plate 5, and a bolt is passed through the third opening for connection with an external structure.

[0032] In this embodiment, if Figure 2 , Figure 3 As shown, the first end side wall and the second end side wall of the protection bar 1 on each protection mesh are respectively connected with a flange plate 2, and the flange plate 2 on the first end side wall of the protection bar 1 is flush with the first end of the protection bar 1, and the flange plate 2 on the second end side wall of the protection bar 1 is arranged in a direction close to the first end of the protection bar 1 and at a certain distance from the second end of the protection bar 1. When in use, one of the two adjacent protection meshes is turned over, and the flange plates of the two adjacent protection meshes are overlapped, so that the first end flange plate group and the second end flange plate group overlapped up and down are formed on the first end side wall and the second end side wall of the protection bar 1, respectively.

[0033] During installation, firstly, bolts are inserted through the third opening of the first connecting plate 5 to connect with the ground, so that the first sleeve 4 is fixed on the ground. Then, the first end flange plate group of the two overlapping adjacent protective meshes is sleeved on the first sleeve 4, and the second sleeve 7 is passed through the second end flange plate group, so that the second connecting plate 8 is blocked outside the second end flange plate group. The rotating shaft 3 is inserted into the second sleeve 7 and the first sleeve 4 from top to bottom through the second opening of the second connecting plate 8, so that the two adjacent protective meshes can rotate around the rotating shaft 3.

[0034] When dismantling is required, first pull out the rotating shaft 3, remove the second sleeve 7, then remove the two overlapping protective meshes from the first sleeve 4, and finally remove the bolt connection between the first connecting plate 5 and the ground.

[0035] The edge protection mesh connection structure of the utility model can make two adjacent protection meshes rotate relative to each other at any angle, and the installation and disassembly are simple and convenient.
