The invention provides an air pressurization type sealing quick
insertion gun head. The air pressurization type sealing quick
insertion gun head comprises
insertion gun
nozzle grooves, sealing gasketinner chambers, fixed rods, tension springs,
polytetrafluoroethylene sealing balls, buffer springs, connecting rods, buffer plates and protective pads, the insertion gun
nozzle grooves are symmetrically arranged in the left side and the right side of an insertion gun seat, the sealing
gasket inner chambers are arranged at the left sides of the insertion gun
nozzle grooves, the tension springs arearranged at the internal right sides of the sealing
gasket inner chambers, the
polytetrafluoroethylene sealing balls are arranged on the left end surfaces of the tension springs, and the above designsolves the problem of incomplete sealing storage of an original liquid charging gun. The fixed rods are arranged at the left side and the right side of the rear end surface of the liquid charging gun,the buffer springs are mounted at the internal rear sides of the fixed rods, the connecting rods are mounted on the front end surfaces of the buffer springs, the buffer plates are mounted on the front end surfaces of the connecting rods, and the protective pads are arranged on the front end surfaces of the buffer plates, and the above design solves the problem of very easy wearing of the originalliquid charging gun. The air pressurization type sealing quick insertion gun head has the advantages of reasonable structure, safety in use, wearing avoiding and good sealing effect.
