Multi-layer circuit board convenient to install

Abstract

The utility model discloses a multilayer circuit board convenient to install, which comprises an upper single-sided board and a double-sided board, the upper single-sided board is installed at the top end of the double-sided board, a lower single-sided board is installed at the bottom end of the double-sided board, and limiting structures are arranged at corners of the upper single-sided board, the double-sided board and the lower single-sided board. The limiting structure comprises a sliding groove, a sliding rail, a connecting hole, a fixing hole, a sliding block, a positioning hole and a limiting column. The limiting structure is arranged, the positioning grooves in the bottom end of the upper single-sided board and the top end of the lower single-sided board are clamped and positioned with the protruding blocks at the two ends of the double-sided board respectively, after the panels are preliminarily connected, the fixing holes, the connecting holes and the positioning holes correspond to one another in position, and the sliding blocks at the bottoms of the limiting columns slide to the sliding rails along the sliding grooves; and the sliding blocks are rotated in the sliding rails to be away from the sliding grooves to achieve locking and fixing, so that the multiple layers of panels are convenient to mount and dismount, the interior is convenient to maintain, and operation is simplified.
