Plate-type thickness gauge for composite insulation board

The utility model discloses a plate-type thickness gauge for a composite material insulation board, which comprises a bedplate, baffle plates are arranged on two sides of the top end of the bedplate, a limiting mechanism is arranged on one side of each baffle plate, a support column is arranged on one side, far away from the baffle plates, of the top end of the bedplate, and a lifting mechanism is arranged in the support column. The insulation board to be tested is placed on the platen, the side wall of the insulation board abuts against the limiting plate, the telescopic column is pushed to move towards the two sides, meanwhile, the push plate is pushed to move synchronously, the clamping spring is compressed, and after the insulation board is placed well, under the elastic force effect of the clamping spring, the insulation board is clamped by the clamping spring. The push plate and the telescopic column are pushed to move towards one side close to the insulation board, that is, the limiting plate is pushed
