DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below 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 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.

[0022] Please refer to Figures 1-4 , a connecting flange with a protection structure of the present utility model includes two pipe bodies. A docking flange 2 is fixedly arranged at the docking end of the pipe body. A protective shell 3 is arranged on one side of the docking flange 2. A cavity 7 penetrated by the pipe body is arranged on the protective shell 3. A limiting plate 4 is fixedly arranged on the periphery of the cavity 7. A limiting bolt 6 is arranged on the limiting plate 4. The limiting bolt 6 is threadedly connected with the limiting plate 4. The bottom end of the limiting bolt 6 can contact the outer wall of the pipe body. Docking plates 5 are arranged on the peripheries of the two protective shells 3. A first sealing ring is arranged between the two docking plates 5;

[0023] In this embodiment, the two docking flanges 2 can be fixed by bolts. After the two docking flanges 2 are docked, slide the protective shell 3 so that the two docking flanges 2 are located inside the two protective shells 3. Then rotate the limiting bolt 6 to limit the limiting plate 4 on the pipe body by the limiting bolt 6. At this time, the positions of the two protective shells 3 will be fixed. At this time, the two docking plates 5 can contact, and the two docking plates 5 will squeeze the first sealing ring. By providing the first sealing ring, the sealing performance between the two docking plates 5 can be ensured;

[0024] Through the two protective shells 3, the docking flange 2 can be protected, so that the docking flange 2 will not be exposed to sunlight and rain for a long time, and the docking flange 2 is not easily rusted. It can not only improve the service life of the docking flange 2, but also avoid the problem of difficult disassembly of the docking flange 2.

[0025] In this embodiment, a second sealing ring is arranged on the inner wall of the cavity 7. By providing the second sealing ring, the sealing performance at the cavity 7 can be ensured, and the sealing performance at the protective shell 3 can be further improved.

[0026] In this embodiment, a first protective plate 12 and a second protective plate 13 are respectively arranged on the peripheries of the two protective shells 3, and the first protective plate 12 is located outside the second protective plate 13. As Figure 3 shown, after the two docking plates 5 are docked, by providing the first protective plate 12 and the second protective plate 13, it can make the external water flow not easily contact the docking part of the two docking plates 5, and further improve the protection effect of the protective shell 3 on the docking flange 2.

[0027] In this embodiment, a plurality of first support rods 8 are fixedly arranged on the docking flange 2. A cavity 7 is provided inside the first support rod 8, and a spring 11 is arranged inside the cavity 7. One end of the spring 11 is provided with a second support rod 9, and one end of the second support rod 9 is connected to the inner wall of the protective shell 3. When docking and fixing the two docking flanges 2, first slide the protective shell 3 to stretch the spring 11 by the second support rod 9, and then rotate the limit bolt 6 to limit the protective shell 3 by the limit plate 4. At this time, the two docking flanges 2 can be docked and fixed. After the docking flanges 2 are docked, loosen the limit bolt 6, and the spring 11 rebounds, which can make the two second support rods 9 pull the protective shell 3 to reset, so that the two docking plates 5 can be in contact with each other.

[0028] In this embodiment, a plurality of locking bolts 10 for limiting the second support rod 9 are provided on the protective shell 3. By providing the locking bolts 10, the second support rod 9 and the protective shell 3 can be easily assembled.
