More Information
Summary:The utility model relates to a hydraulic cylinder oil-leakage-preventing end cover which comprises a through hole penetrating through the end cover. A catcher groove is formed in the end cover and located in the inner wall face of the through hole, an included angle is formed between the extension direction of the catcher groove and the axial direction of the through hole, and the included angle is larger than 0 degree and smaller than 180 degrees. In the using process, when oil leakage of a hydraulic cylinder happens especially after a sealing ring is damaged, oil can not overflow to be outside the hydraulic cylinder and flows into the catcher groove, the hydraulic cylinder can continue to work, maintenance can be carried out later in a proper time period, the sealing ring is replaced, and work efficiency is improved.
