Specific embodiment

By the technology contents of the utility model are described in detail, construction feature, are reached purpose and efficacy, reality is hereby enumerated below It applies example and attached drawing is cooperated to be explained in detail.

In the description of the present invention, it should be understood that term " center ", " longitudinal direction ", " transverse direction ", "front", "rear", The orientation or positional relationship of the instructions such as "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" is based on attached drawing institute The orientation or positional relationship shown, is merely for convenience of describing the present invention and simplifying the description, rather than indication or suggestion is signified Device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to this is practical The limitation of novel protected range.

The utility model provides a kind of tubular membrane hole menbrane aerator dedicated bushing pipe, including for connecting aeration connector One tube body 1, first tube body 1 are equipped with baffle ring 2 in one end far from aeration connector, and the baffle ring 2 is in separate aeration connector Side is equipped with connection ring 3, and the connection ring 3 is closely arranged with the second tube body 4 for connecting tail connector, and the baffle ring 2 is along the The axial direction of one tube body 1 offers through-hole, and second tube body 4 is equipped with the slide bar 5 being slidably connected with through-hole, and the slide bar 5 is located at End in first tube body 1 is connected with limited block 6；Support tube 7, the support tube 7 and are coaxially provided in first tube body 1 Circumferential direction between one tube body 1 along support tube 7 is laid with several reinforcing ribs 8；The excircle of first tube body 1 and the second tube body 4 Face is equipped with non-return ring 9.
