Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides, for example Figure 1-7 The novel ring network box shown includes a cabinet 3 and a terminal device 1 installed inside the cabinet 3;

[0029] An expansion assembly 2 is located on the inner side of the front outer wall of cabinet 3, near the left side.

[0030] The right door 4 is located on the inner side of the front outer wall of cabinet 3, near the left side of the transmission connection.

[0031] A second front left door 7 is provided on the right side of the right door 4. The first front left door 6 is connected to the right side of the second front left door 7. The left door 5 is connected to the inner side of the right outer wall of the cabinet 3. First, the cabinet 3 is placed in the predetermined installation position to ensure that the cabinet 3 is installed stably and horizontally. Then, the terminal device 1 is installed inside the cabinet 3. Electrical connections and fixation are carried out according to the design requirements to ensure that the device is installed firmly and the electrical connections are correct and can operate normally. Next, the expansion assembly 2 is installed in the predetermined position near the left side of the inner side of the front outer wall of the cabinet 3. Electrical connections and fixation are also completed to enable it to effectively cooperate with the terminal device 1 and the electrical system inside the cabinet 3. The right door 4, the first front left door 6, the second front left door 7 and the left door 5 are installed in the corresponding positions of the cabinet 3 through the transmission connection structure.

[0032] Windproof buckles 14 are installed between cabinet 3 and right door 4, first front left door 6, second front left door 7 and left door 5. Multiple fastening screws 13 are installed between multiple windproof buckles 14 and cabinet 3 to restrict the position of windproof buckles 14 and cabinet 3, right door 4, first front left door 6, second front left door 7 and left door 5. Windproof buckles 14 are installed at the connection between cabinet 3 and each door. The mounting holes of windproof buckles 14 are aligned with the pre-set screw holes on the surface of cabinet 3 and door. Fastening screws 13 are passed through the mounting holes of windproof buckles 14 and screwed into the screw holes of cabinet 3 and door. The screws are gradually tightened to firmly fix the windproof buckles 14 between cabinet 3 and door, restricting their relative position.

[0033] like Figure 6 and Figure 7 As shown, a pad 15 is provided on one side of each of the multiple windproof buckles 14 to fill the gap between the windproof buckle 14 and the cabinet 3, right door 4, first front left door 6, second front left door 7 and left door 5. Threaded holes 16 are provided inside the cabinet 3, right door 4, first front left door 6, second front left door 7 and left door 5 for fastening screws 13 to be screwed in, so as to restrict the position between the windproof buckle 14 and the cabinet 3, right door 4, first front left door 6, second front left door 7 and left door 5.

[0034] The pads 15 on one side of the multiple windproof buckles 14 mainly fill the gaps between the windproof buckles 14 and the cabinet 3, right door 4, first front left door 6, second front left door 7 and left door 5, making the contact between the windproof buckles 14 and the cabinet 3 and the doors tighter and enhancing the stability of the connection. The threaded holes 16 inside the cabinet 3, right door 4, first front left door 6, second front left door 7 and left door 5 are used in conjunction with the fastening screws 13 to make the windproof buckles 14 tightly fixed between the cabinet 3 and the doors, preventing them from moving at will. This ensures that the connection between the doors and the cabinet 3 remains stable under various working conditions, and the windproof buckles 14 can continuously play a windproof role.

[0035] like Figure 6 and Figure 7 As shown, windproof buckles 14 are also provided between the right door 4 and the second front left door 7, and between the second front left door 7 and the first front left door 6.

[0037] like Figure 3 As shown, a cabinet welding point 8 is provided on the outer right side of the cabinet 3, and a connecting pin 10 is provided between the first front left door 6 and the second front left door 7.

[0038] During the manufacturing process of the ring network box, different plates or components are connected at the welding point 8 of the box body through welding. The connecting pin 10 set between the first front left door 6 and the second front left door 7 plays a role in stabilizing the connection between the two doors. When the two doors are closed, the connecting pin 10 restricts the relative displacement between the two doors, thereby enhancing the sealing and stability of the connection between the two doors.

[0039] like Figure 5 As shown, door locks 11 are installed at the front end of the right door 4 and on the right side of the left door 5.

[0040] By inserting a key into the door lock 11, the rotation of the lock cylinder is controlled, causing the bolt behind the door to separate from the cabinet body 3 and the lower stop bar 9, thereby enabling the opening of the right door 4, the left door 5, the first front left door 6, and the second front left door 7.

[0041] like Figure 1 As shown, a top cover 12 is fixedly connected to the upper outer wall of the cabinet 3 to guide the direction of rainwater and snow, and a lower baffle 9 is fixedly connected to the lower outer wall of the cabinet 3.

[0042] When rain or snow falls on the top cover 12, due to gravity and the inclined surface of the top cover 12, the rainwater will flow down the inclined surface, and the snow will also flow along this path after melting, thus preventing rain or snow from accumulating on the top of the cabinet 3. The lower baffle 9 has a certain height and can block foreign objects from the ground to a certain extent. The lower baffle 9 can also be used in conjunction with the ground foundation or other protective facilities to enhance the stability of the connection between the cabinet 3 and the ground.

[0043] The implementation principle of this embodiment is as follows: First, place the cabinet 3 in the predetermined installation position to ensure that the cabinet 3 is installed stably and horizontally. Then, install the terminal device 1 inside the cabinet 3 and make electrical connections and fixation according to the design requirements to ensure that the device is installed firmly and the electrical connections are correct and can operate normally. Next, install the expansion assembly 2 inside the front outer wall of the cabinet 3 at the preset position near the left side. Similarly, complete the electrical connection and fixation work to enable it to effectively cooperate with the terminal device 1 and the electrical system inside the cabinet 3. Install the right door 4, the first front left door 6, the second front left door 7, and the left door 5 in the corresponding positions of the cabinet 3 through the transmission connection structure. Install the windproof buckle 14 at the connection between the cabinet 3 and each door. Align the mounting holes of the windproof buckle 14 with the preset screw holes on the surface of the cabinet 3 and the door. Use the fastening screw 13 to pass through the mounting holes of the windproof buckle 14 and screw it into the screw holes of the cabinet 3 and the door. Gradually tighten the screw to make the windproof buckle 14 firmly fixed between the cabinet 3 and the door, restricting their relative position.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
