Technical Field

[0001] This utility model relates to the field of power fitting reinforcement technology, specifically a power fitting reinforcement connection device. Background Technology

[0002] Power fitting reinforcement connection devices are metal components used to enhance the stability of connections between transmission line towers, conductors, and equipment; However, when connecting transmission line towers, different tower heights require reinforcement connection devices of different lengths for assembly and combination. Connection structures of different lengths limit their application range. Multiple sets of reinforcement connection devices are not convenient for combined installation, reducing the production of connection devices of different lengths. Connection structures of the same length can be assembled and combined to be suitable for connecting towers of different heights, and can be reused after disassembly, reducing material waste. However, they do not increase the stability of the installation between connection devices on the same horizontal plane. Utility Model Content

With the cooperation of multiple positioning holes, the external bolt passes through the connecting rod and the positioning hole to fix the position of the installed connecting rod, increasing the stability of the support.
