The invention relates to the technical field of jigs, and discloses an automatic sealing
pneumatic pressure maintaining jig capable of preventing gas leakage, the automatic sealing
pneumatic pressure maintaining jig comprises a base, a rotating arm and a lower punch, the rotating arm is rotatably connected to the surface of the base, the lower punch is rotatably connected to the end, away from the base, of the rotating arm, and a gas path connector is fixedly connected to the middle of the rotating arm; a fixing
assembly used for fixing the gas leakage prevention jig is arranged on the gas circuit connector, a wrapping
assembly used for preventing gas leakage is arranged on the gas circuit connector, an electric telescopic rod is electrically controlled by a
gas pressure controller to stretch out and draw back to drive a second wrapping clamp to wrap an external gas
pipe, and the gas leakage position is sealed through the electric telescopic rod and the second wrapping clamp. Gas loss and environmental
pollution can be reduced, meanwhile, safety accidents such as
fire disasters, explosion and poisoning caused by gas leakage are avoided, then serious threats to safety of factories and operators are avoided, the risk of the accidents can be reduced by sealing the gas leakage position, and harm to the factories and the operators is avoided.
