The invention discloses an assembling and disassembling facilitating power cable bridge comprising a bridge body, a first iron hoop buckle and control blocks. The bridge body is internally provided with ventilating holes, and the left side of the bridge body is connected with clamp grooves. The control blocks are arranged on the internal wall of the clamp grooves, and the bottom parts of the control blocks are provided with connecting rods. First connecting blocks are fixed on the internal side of the bridge body, and first supporting blocks are connected on the bottom end of the first connecting blocks. The first iron hoop buckle is arranged on the bottom part of the first connecting blocks. Second connecting blocks are installed on the internal wall of the bridge body, and second supporting blocks are arranged on the top end of the second connecting blocks. According to the assembling and disassembling facilitating power cable bridge, the clamp grooves are arranged, the external wallof the control blocks is fit with the internal side of the clamp grooves, the bridge bodies are enabled to be connected with each other through the effect of the clamp grooves and the convex blocks,the convex blocks can be stabilized by the control blocks and the bridge body is enabled not to waggle.
