Embodiment
[0032] This embodiment provides a ring network cabinet, including a lower door hard interlock mechanism, such as figure 1 with 2 As shown, the lower door hard interlock mechanism includes a first link 1 , a second link 2 and a third link 3 .
[0033] The first connecting rod 1 is arranged vertically in the cabinet body 4, and has a first end 11 and a second end 12 respectively arranged at both ends of the length direction, such as figure 2 with 3 As shown, the first connecting rod 1 includes: two connecting rod parts 13, respectively connected to the corresponding second connecting rod 2 and the third connecting rod 3; Between the connecting rod parts 13, there are a first screw part 15 and a second screw part 16 respectively threadedly connected with the two connecting rod parts 13; Lock connection. In this embodiment, one of the first screw part 15 and the second screw part 16 is a left-handed thread, and the other is a right-handed thread. The main body of the first ...

The invention provides a lower door hard interlocking mechanism of a ring main unit and the ring main unit. When a lower door needs to be locked, a second connecting rod rotates anticlockwise around the rotation center of the second connecting rod under the action of external force, so that a first connecting rod is driven to move upwards, and the first connecting rod pulls a third connecting rod to rotate anticlockwise around the rotation center of the third connecting rod, therefore, the bolt is inserted into the insertion hole of the lower door and locked with the lower door in a matched mode. As the respective rotation centers of the second connecting rod and the third connecting rod are positioned on the cabinet body or the mechanism, a guide hole is not required to be formed in the first connecting rod in the prior art, so that the structure of the first connecting rod is not damaged and is not easy to deform. The width direction of the second connecting rod and the width direction of the third connecting rod extend along the height of the cabinet body, when an operator drives the door hard interlocking mechanism to move downwards under the condition that the lower door is not closed tightly, the width direction of the flat plate is subjected to extrusion force, and the width of the flat plate is far larger than the thickness of the flat plate, in comparison with the prior art, therefore, the second connecting rod and the third connecting rod are not easy to deform.
Description
technical field [0001] The invention relates to the technical field of ring network cabinets, in particular to a lower door hard interlock mechanism of the ring network cabinet and the ring network cabinet. Background technique [0002] With the rapid development of the economy and the continuous emergence of high-rise buildings and large public buildings in cities, the reliability of power supply is required to be higher and higher. Many users require two or more power supplies for power supply. By establishing a ring network structure as the The main power distribution network can effectively improve the reliability of power supply, ensure the continuity of power supply, and minimize the impact of power distribution equipment failure and maintenance blackout. As an important equipment in the ring network operation mode, the ring main unit is in the distribution The application in network transformation is also more and more extensive. [0003] In order to ensure the safet...
