A circuit board positioning device comprises a crossbeam (1) and a buckle (5). A first side surface of the crossbeam (1) forms a circuit board supporting surface (11), the first side surface is provided with a first clamping block (2) and a second clamping block (3), the first clamping block (2) forms a first positioning groove (21), the second clamping block (3) forms a second positioning groove (31), and the first positioning groove (21) and the second positioning groove (31) are used for limiting two opposite side edges of a circuit board (8). One end of the buckle (5) can be rotatably installed to the crossbeam (1) around a rotating shaft, a locking mechanism (7) used for locking the buckle (5) and the crossbeam (1) when the buckle (5) is at a closing position is disposed between the buckle (5) and the crossbeam (1), and the surface of the buckle (5) facing the crossbeam (1) is provided with at least one elastic pressing piece (6) protruding towards the crossbeam (1) when the buckle (5) is at the closing position. By means of the circuit board positioning device, a circuit board can be protected from being easily damaged in case of vibration. |
