[0003] Specifically, the sealing nozzle usually includes an injection connection tube that is sleeved on the outside of the screw head and fixedly connected to the screw sealing head. The screw sealing head is provided with a pressurized sealing cavity, and the outside of the screw head is placed in the pressurized sealing cavity to achieve the colloid solidification of the outer periphery of the screw head. The inside of the injection connection tube is connected to the pressurized sealing cavity, so that the glue can be injected into the pressurized sealing cavity, thereby achieving sealing.

[0004] However, the connection between the aviation fastener sealing nozzle and the rubber barrel is usually a threaded connection. Multiple rotations and disassembly can easily cause gaps in the connection, which in turn leads to leakage of the rubber and waste of resources. The utility model improves the above-mentioned problem and specifically relates to an aviation fastener sealing nozzle with good connection sealing performance. Utility Model Content
