Civil air defense door testing device and manufacturing method thereof

The invention discloses a civil air defense door testing device, which comprises a base and two positioning devices. Each positioning device comprises a plurality of buffer plates; the bottom end of each buffer plate is connected with the base; a first positioning plate is connected to the top end of each buffer plate; a second positioning plate perpendicular to each first positioning plate is arranged on the corresponding first positioning plate; a plurality of air cylinders are arranged on the base; a connecting plate is arranged above each air cylinder; the bottom parts of the connecting plates are connected with piston rods of the air cylinders at the same time; two sliding plates are arranged on the top ends of the connecting plates; front ends of the sliding plates penetrate throughthe second positioning plates and can slide along up-and-down directions of the second positioning plates; lower pressing plates are arranged above the first positioning plates; two ends of the lowerpressing plates are connected with the top parts of the sliding plates. According to the civil air defense door testing device provided by the invention, a civil air defense door is clamped and positioned through the two positioning devices, and then is subjected to an anti-collision test through balancing weights, so that unqualified products are effectively prevented from flowing into the market, and the civil air defense door testing device has the beneficial effects of convenience in operation, simple structure, difficulty in damage, and the like.
