It plays a connecting role, that is, connecting and assembling the conveying pipeline and the discharge port of the filling and discharging device to facilitate subsequent insertion and discharging. In response, Chinese patent application number CN201721876502.6 discloses a sterile tube connector for aseptic filling of a bag-in-a-box system. The connector includes an inner tube, an outer tube for fixing a sterile sealing device, a sterilization device, a sterile sealing device, and an inlet tube. One end of the inner tube is connected to the filling machine pipe, and the other end is connected to the inlet tube. The outer tube is installed on the outer wall of the inner tube at the end connected to the inlet tube. The sterilization device is connected to both sides of the outer tube. The inlet tube has an inlet tube connector, which is movably connected to the outer tube. An inner cavity is formed between the outer wall of the inner tube, the inner wall of the outer tube, and the inner wall of the inlet tube connector. A sterile sealing device is provided within this inner cavity. However, the existing connection devices are inconvenient to assist in the assembly and insertion according to the needs of use, which affects the efficiency of operation and the connection effect. Therefore, in order to solve the above problems, a quick-connect and sealing paint filling pipe connector is proposed. Utility Model Content
