End, which is equipped with, to be closed at internal thread part position with the matched internal thread part of screw thread on cylinder rod, the centre bore equipped with the first sealing
Circle；
The second sealing ring is equipped between the fixing piece and second flange；
The first flange left side is equipped with toroidal cavity, is equipped with third sealing ring in the circular ring type groove.
Further, first sealing ring, the second sealing ring, third sealing ring are respectively rubber seal.
Further, the fixing piece includes the interconnecting piece and fixed part being connected, and the interconnecting piece is and second flange
The flange arrangement of connection, the internal thread part and the first sealing ring are correspondingly arranged with fixed part respectively.
Further, the bellows is waist-drum-shaped structure.
Further, the first flange, second flange and fixing piece are respectively hard plastic part.
Compared with the existing technology, a kind of cylinder rod protective jacket described in the utility model has the advantage that
In a kind of cylinder rod protective jacket described in the utility model, using bellows structure, bellows contraction distortion is utilized
Suitable for the flexible requirement of cylinder rod, in use, protective jacket is sleeved on cylinder rod, first flange is connected with cylinder body, fixing piece
It is threadedly coupled with connection on cylinder rod, due to being provided with the first sealing ring, first flange between fixing piece and cylinder rod polished rod portion
The second sealing ring being arranged between fixing piece is provided with second flange between first flange and cylinder body, guarantee that cylinder rod moves back and forth
When sealed environment, guarantee the tidiness of cylinder rod.
