Abstract

The utility model belongs to the technical field of double-sided circuit boards, and particularly relates to a double-sided circuit board convenient to disassemble, assemble and maintain, which comprises an L-shaped frame. The number of the L-shaped frames is four, the four L-shaped frames are annularly arranged, the inner wall of each L-shaped frame is provided with a telescopic mechanism, the bottom of each L-shaped frame is provided with a positioning mechanism, and the inner wall of each L-shaped frame is movably provided with a double-sided circuit board body; supporting assemblies are arranged on the two sides, away from the magnetic suction plate, of the bottom of the L-shaped frame. Through the arrangement of a telescopic long rod, a limiting plate block, a circular notch, a groove, a magnetic suction plate and a positioning pin, the telescopic long rod can stably slide on the inner wall of an L-shaped frame through the arrangement of the circular notch, and the L-shaped frame can be freely adjusted according to double-sided circuit board bodies of different sizes through the cooperative use of the telescopic long rod and the limiting plate block; and meanwhile, angle deviation among the four sets of L-shaped frames can be prevented, and it is ensured that the L-shaped frames can clamp and fix different plates.
