[0019] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0020] Referring to Figures 1-4 A kind of vacuum cover of convenient replacement oil seal, including vacuum cover body 1, vacuum cover body 1 is provided with vacuum shaft center 3, vacuum cover body 1 side is located at the outside of vacuum shaft center 3 and is equipped with oil seal cover 4;
[0021] Vacuum cover body 1 is located at the outside of through hole and is provided with first oil seal groove 11 in the middle part of vacuum cover body 1, and installation groove is set up at the side of oil seal cover 4 of vacuum cover body 1, second oil seal groove 12 is set up at the side of installation groove in vacuum cover body 1, wherein oil seal assembly is installed by first oil seal groove, wherein the specific structure, working principle of oil seal assembly are the existing product that has been disclosed on the market at present, therefore, the utility model does not add more elaboration.
[0022] Meanwhile, oil seal cover 4, vacuum cover body 1 are fixed between by multiple bolts.
[0023] Meanwhile, a plurality of mounting through holes are annularly and equidistantly formed in the oil seal cover 4, the oil seal cover 4 is inserted into the mounting groove, and the bolt is screwed into the mounting hole, so that the oil seal cover 4 is mounted on the vacuum cover body 1.
[0024] Further, when the oil seal cover 4 is inserted into the mounting groove, the end surface of the oil seal cover 4 is flush with the end surface of the vacuum cover body 1.
