Description
Technical Field
The utility model relates to a waterproof oil seal for a driving rod.
Background
Oil seals are a common designation for seals in general, and are often mounted on shafts for sealing. Electric putter can set up the oil blanket between its casing and the telescopic push rod and be used for waterproof dustproof, because telescopic push rod can reciprocating motion, so telescopic push rod can produce the power along telescopic push rod axial two directions in front and back to the oil blanket, but, the oil blanket is different again in the structure of telescopic push rod axial front and back both sides, so can cause the oil blanket when telescopic push rod back-and-forth movement, the deformation of emergence is different, in long-time use, the oil blanket damages easily.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems pointed out in the background art, the utility model provides a waterproof oil seal for an active rod, which can realize bidirectional sealing and is convenient to install.
The technical scheme of the utility model is realized as follows:
the utility model provides a waterproof oil blanket of using of initiative pole, includes annular sealing member body, the axial both sides face of sealing member body on be equipped with annular deformation groove respectively, the lateral wall in deformation groove on be equipped with annular spread groove, the spread groove on be equipped with annular spring, the inside of sealing member body be equipped with and be equipped with annular metal reinforcement, metal reinforcement on be equipped with the solid fixed ring that extends to the sealing member body outside, solid fixed ring on be equipped with fixed connection hole.
The sealing element is further provided with a fixing ring which is of a circular ring structure, the fixing ring and the sealing element body are coaxially arranged, and the fixing ring is arranged corresponding to the middle position of the sealing element body.
The utility model is further provided that the metal reinforcing piece comprises a first annular reinforcing part, two second annular reinforcing parts protruding inwards are arranged on the inner side of the first annular reinforcing part, and the fixing ring is arranged on the outer side of the first annular reinforcing part.
The utility model is further arranged in that the inner side surface of the sealing element body is provided with a concave accommodating groove, and the accommodating groove is filled with lubricating oil.
The utility model is further arranged in that two ends of the inner side surface of the sealing element body are sealing contact surfaces, and a concave deformation groove II is arranged between the sealing contact surfaces and the accommodating groove.
By adopting the technical scheme, the utility model has the beneficial effects that:
according to the waterproof oil seal for the driving rod, the two axial sides of the sealing element body form the sealing structures, and bidirectional sealing can be achieved, so that the problem of different deformation of the sealing element body caused by movement of the telescopic push rod can be solved to a certain extent, and the sealing element body can be fixed on a shell of equipment through the fixing ring on the sealing element body, so that the installation of the sealing element body is facilitated.
