Abstract

This utility model discloses a waterproof coating spray gun device that facilitates nozzle replacement. It includes a spray gun body, a nozzle body, four sets of protrusions, a snap-fit ​​assembly, and a limiting assembly. The four sets of protrusions are fixedly installed in a ring array on the outer wall of the nozzle body. The nozzle body is connected to the spray gun body via the protrusions and the snap-fit ​​assembly. The limiting assembly is installed on the spray gun body. The snap-fit ​​assembly and limiting assembly enable rapid nozzle replacement. Installation is completed simply by inserting the protrusion on the nozzle body along the guide groove of the snap-fit ​​cylinder, rotating it a certain angle to snap it into the ring groove, and then using the limiting assembly for fixation. Disassembly is performed in reverse, making it simple and convenient. This design shortens nozzle replacement time and improves construction efficiency, making it particularly suitable for construction projects with strict time requirements. It can effectively reduce downtime caused by nozzle replacement and ensure construction progress.
