In order to achieve the above object, the present invention provides the following technical solutions: a dynamic and static composite sealing system of a door shaft comprises a sealing sleeve and the door shaft, wherein a gland is arranged at the opening end of the sealing sleeve through a positioning bolt, a first through hole penetrating through the side wall of the sealing sleeve opposite to the opening end of the sealing sleeve is arranged on the side wall of the sealing sleeve on the sealing sleeve, a second through hole penetrating through the gland is arranged on the gland corresponding to the first through hole, and the door shaft penetrates through the first through hole and the second through hole; and a sealing structure is arranged in the sealing sleeve and used for sealing a gap between the door shaft and the inner wall of the sealing sleeve.
Preferably: the sealing structure comprises an annular filler, two annular compression rings and two springs, wherein the annular filler is slidably sleeved on the outer circumferential wall of the door spindle, the two annular compression rings are arranged between the two springs, and the filler is arranged between the two compression rings; the spring is in a compressed state.
Preferably: the opposite surfaces of the two compression rings are respectively provided with an annular protruding part, the side wall of the filler corresponding to the protruding parts is provided with an annular sunken groove, and the sunken groove is positioned in the center of the side wall of the filler; the protruding part is inserted into the concave groove and matched with the concave groove in shape and size.
Preferably: the cross section of the protruding portion is isosceles trapezoid, and the thickness of the protruding portion gradually decreases along the direction from the pressing ring to the filler.
Preferably: one end of the pressing cover, which is opposite to the sealing sleeve, extends into the sealing sleeve and applies pressure to the spring.
The beneficial effect of adopting above technical scheme is:
according to the sealing device, pressure is continuously applied to the two compression rings through the two springs, so that the compression rings apply pressure to the filler, the filler deforms after being extruded, and the filler deforms to a gap between the filler and the inner wall of the sealing sleeve and a gap between the filler and the door shaft, so that the filler continuously plays a sealing role;
this application can extrude the filler to the inner wall and the outer wall of protruding portion through the cooperation of protruding portion and depressed groove, has improved sealed effect.
