Lock nut, lock nut is internally provided with jack hole, and gasket is equipped in jack hole, right on two madial walls of tube body
What is claimed is provided with mounting groove, and sealing ring is equipped in mounting groove, and several protective air-bag bodies are equipped on the madial wall of tube body, prevents
It protects on the outer surface of pneumatophore and is provided with several anti-skidding pillars.
Preferably, the tube body, which is hollow type, reinforces tube body.
Preferably, the lock nut is copper cap.
Preferably, the sealing ring is Double seal ring.
Preferably, the gasket is internally provided with reinforced sheet.
Compared with prior art, the beneficial effects of the utility model are：It can realize that fast sealing formula connects, and bonding strength
Height, it is easy to operate, it is easy to use.
Description of the drawings
The utility model is described in detail by following specific implementations and attached drawing for ease of explanation,.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model middle tube body.
In figure：1- tube bodies；2- external thread sleeves；3- sealing rings；4- protective air-bag bodies；5- lock nuts；6- gaskets.
