A kind of improvement as the utility model with oil sealing screw rod header structure, the oil seal sealing ring are silicone member.
A kind of improvement as the utility model with oil sealing screw rod header structure, oil sealing mounting portion center are logical equipped with oil inlet
Road, one end of the oil sealing mounting portion are equipped with an inclined-plane, are equipped at intervals with several fuel feed holes, the oil sealing mounting portion on the inclined-plane
Other end be equipped at intervals with multiple oil outlets, the oil inlet passage, fuel feed hole are connected to oil outlet, and the oil seal cover is placed on institute
It states and is sealed on oil outlet.
A kind of improvement as the utility model with oil sealing screw rod header structure is equipped with a bullet on the spring fixing portion
Spring, the spring squeeze the oil seal cover by elastic force and are placed on the oil outlet.
A kind of improvement as the utility model with oil sealing screw rod header structure, the oil seal cover are squeezed by oil outlet oil pressure pressure
When pressure, the oil seal cover is opened by oil pressure, and the spring is compressed, when oil pressure disappears, the compressed spring of oil seal cover
It supports again and covers the oil outlet.
Compared with prior art, the utility model has the advantages that: the utility model is equipped in the outer surface of oil sealing mounting portion
An at least ring annular groove has been embedded in oil seal sealing ring in annular groove, and when oil pressure disappears, the compressed spring of oil seal cover is again
Secondary to support when covering oil outlet, the silicon rubber in screw head one end can not pass through between sleeve and screw head, prevent silicon rubber
Into in the sleeve of the screw head other end.Facilitate the weight feed of silicon rubber in this way and keeps the cleaning of screw rod and sleeve.
Detailed description of the invention
