[0005] The utility model discloses the technical scheme is: a multistage water rocket bottle body quick connector of air separator can be installed, it includes one integral forming's connector body, this connector body is along axial and is divided into two sections of through communication, one section is straight-through fast plug connector shell, another section is bottle port connector, and install sealing rubber ring, limit snap spring, ring end cap in straight-through fast plug connector shell, the outer circle of limit snap spring is embedded in the inner wall of straight-through fast plug connector shell, and the inner circle of limit snap spring is formed with the limit thorn piece of interval arrangement, and the outer thread and positioning convex ring are formed on the outside of bottle port connector.
[0006] Further, an active collar is also installed in the straight-through fast plug connector shell, the inner end portion outer wall of the active collar has the inclined surface in contact with the limit thorn piece of limit snap spring, and the outer end portion of the active collar is exposed on the outer end portion of the straight-through fast plug connector shell.
[0007] The through quick connector housing is comparable in length to the bottle mouth connector.
[0008] The through quick connector housing, the sealing rubber ring, the limit snap spring and the movable snap ring and the annular end cover form a through quick connector, which can quickly connect the hollow butt joint of the bottle body bottle mouth or the arrow body.
[0009] When the quick connector is used to connect the spliced water-fire arrow bottle body and the air separator, only one bottle body is needed for each arrow body to realize the connection, so that the assembly of the bottle body and the air separator can be quickly realized, the efficiency is improved, and convenience is brought to the user.
