[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides a technical solution: an insulating ring network cabinet with a protection mechanism, comprising: a ring network cabinet body 1, connecting legs 2 are installed at the four corners of the front surface and the rear surface of the ring network cabinet body 1, the outer side of the connecting legs 2 is connected with a bracket 3 by bolts, one end of the bracket 3 is fixedly connected to the outer frame 4, and a protection net 5 is fixedly connected to the inner side of the outer frame 4, the front section of the protection net 5 is connected with a door 6 through a rotating shaft, and the right side of the front surface of the door 6 is connected to the front surface of the protection net 5 with a lock connecting plate 7, and four connecting columns 8 are arranged at the corners of the protection net 5, and fixing holes 9 are opened at the diagonal positions of the connecting columns 8, and connecting grooves 10 are opened in an array at the lower ends of the connecting columns 8, and the connecting grooves 10 are inserted and connected with the outer frame 4, and the outer frame 4 is also provided with fixing holes 9, and a fixing rod 11 is arranged on the outer side of the connecting column 8, and the fixing rod 11 is inserted and connected with the fixing hole 9, and the cross-sectional area of ​​the fixing rod 11 is smaller than the inner area of ​​the fixing hole 9, and the cross-sectional area of ​​the outer frame 4 is the same as the area of ​​the connecting groove 10.

[0025] When in use, first install the main body 1 of the ring network cabinet on the ground, then insert the four connecting columns 8 into the four corners of the main body 1 of the ring network cabinet, then fix them with cement, insert the outer side frame 4 and the outer side of the protective net 5 into the inside of the connecting groove 10, insert the fixing rod 11 into the inside of the fixing hole 9, so that the outer frame 4 and the connecting column 8 are fixed together, then the hole inside one end of the bracket 3 is docked with the hole inside the connecting leg 2, and then connected by bolts, after closing the door 6, pass the lock through the hole inside the lock connecting plate 7, close it, and the installation is completed without temporary welding installation. When the outer frame 4 and the protective net 5 are hit by external force, the force will be transmitted to the connecting column 8 through the outer frame 4 and the protective net 5, and part of the force will be transmitted to the main body 1 of the ring network cabinet through the bracket 3, and at the same time, the force will be turned into a lateral force through the bracket 3 to reduce the damage to the main body 1 of the ring network cabinet.

[0026] like Figure 1-5 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, the outer surfaces of the outer frame 4, the protective net 5, the door 6 and the connecting column 8 are all wrapped with a polyethylene shell.

[0027] From the analysis of the above structure, it can be known that the polyethylene shell wrapped around the outer surface of the outer frame 4, the protective net 5, the door 6 and the connecting column 8 can not only play a role in protection and oxidation prevention, but also play a role in insulation.

[0028] like Figure 1-5 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, a support plate 21 is connected to the side of the inner side of the connecting column 8 without a hole, and one end of the support plate 21 is connected to the ground. There is a thirty-degree angle between the support plate 21 and the connecting column 8.

[0029] From the analysis of the above structure, it can be known that when the outer frame 4 and the protective net 5 are squeezed by external force, the force will be transmitted to the ground through the support plate 21, providing a certain support force for the connecting column 8 to prevent the connecting column 8 from bending and collapsing.

[0030] like Figure 1-5 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the upper end and the lower end of the outer side of the protective net 5 are connected with a reflective warning strip 22.

[0031] From the analysis of the above structure, it can be seen that at night, the reflective warning strip 22 will emit reflected light to remind passers-by and drivers.

[0032] like Figure 1-5 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, a ceiling 23 is provided on the upper end of the connecting column 8, and connecting holes are provided at the four corners of the ceiling 23 and the upper end of the connecting column 8. The ceiling 23 and the connecting column 8 are connected by bolts.

[0033] From the analysis of the above structure, it can be known that during installation, the ceiling 23 is placed on the upper end of the connecting column 8, the connecting holes at the four corners of the ceiling 23 are adjusted to be concentric with the connecting holes at the upper end of the connecting column 8, and then they are connected by bolts. This can provide a rain shield for the ring network cabinet body 1 at the lower end, preventing rainwater from entering the interior of the ring network cabinet body 1.

[0034] like Figure 1-5 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the lower surface of the ceiling 23 is fixedly connected with a support rod 24, and a distance equal to the thickness of the outer frame 4 is set between the end of the support rod 24 and the corner of the ceiling 23.

[0035] From the analysis of the above structure, it can be known that after the ceiling 23 is installed on the upper end of the connecting column 8, the support rods 24 on the lower surface of the ceiling 23 will support the outer frame 4 on the outside, thereby improving the stability of the outer frame 4.

[0036] like Figure 1-5As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the lower end of the outer side of the fixing rod 11 is provided with an oblique angle.

[0037] From the analysis of the above structure, it can be seen that when the fixing rod 11 is inserted into the fixing hole 9 , the bevel provided at the lower end of the outer side of the fixing rod 11 can play a guiding role, facilitating the insertion of the fixing rod 11 .

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
