| description | The invention provides a high-sealed copper pipe nitrogen charging device. The device comprises a seat body and a gas receiving core rod movably connected to the seat body, wherein the gas receiving core rod is hollow to form a gas conveying channel; and a rotary pressing gas cylinder is arranged on the seat body, and a gas charging connector connected with the input end of the gas conveying channel is arranged on a gas cylinder shaft of the rotary pressing gas cylinder. Compared with the background art, the scheme has the beneficial effects that the gas charging connector can be directly connected with the gas conveying channel of the gas receiving core rod under the driving of the rotary pressing gas cylinder, the gas charging connector is kept being tightly connected with the gas conveying channel in the nitrogen charging stage, and the gas charging connector can be rotated to a position which does not affect the resetting of the gas receiving core rod in the stage of needing no nitrogen charging; in addit |
