Detailed Description
The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.
It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
As shown in fig. 1 to 6, the utility model provides a diffusion pump mouth flange, it includes:
a lower flange 1 including a first through hole 11; the outer wall of the upper part of the lower flange 1 is provided with a first thread 12;
an upper flange 2 including an upper fixing member 21, a lower connecting member 22, and a second through hole 211 penetrating the upper fixing member 21; the second through hole 211 is matched with the first through hole 11; a second thread 212 is arranged on the outer wall of the lower part of the upper fixing piece 21, the lower connecting piece 22 is a cylinder with a third through hole 223, and a third thread 221 matched with the first thread 12 and the second thread 212 is arranged on the inner wall of the lower connecting piece 22;
wherein, a first lug 13 is arranged on the outer wall of the lower flange 1; and a second lug 222 matched with the first lug 13 is arranged on the outer wall of the lower connecting piece 22.
