FIG. 2 is a half-sectional view of the overall structure of the present invention;
fig. 3 is a schematic view of the overall structure of the present invention.
In the figure: a seal ring body 1; a fixing groove 11; a bottom ring 2; a first annular middle ring 3; a second annular middle ring 4; a top ring 5; and a leakage-proof ring 6.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
Referring to fig. 1-3, the present invention provides a technical solution:
the utility model provides a sealing washer based on inside and outside double-deck seal structure, includes sealing washer body 1, and sealing washer body 1 includes foundation ring 2, and 2 top surface integrated into one piece of foundation ring have first annular center ring 3, and 3 top surface integrated into one piece of first annular center ring have second annular center ring 4, and 4 top surface integrated into one piece of second annular center ring have top ring 5, and the equal integrated into one piece of bottom surface inner wall of foundation ring 2, the top surface inner wall of top ring 5 have leak protection circle 6.
In this embodiment, fixed slot 11 has been seted up to 1 inner wall of sealing washer body, through the protruding position joint cooperation on fixed slot 11 and the corresponding part, effectively prevents that sealing washer body 1 from droing from the corresponding part outer wall.
Besides, the outer contour of the bottom ring 2 is of an inverted frustum-shaped structure, and the inverted frustum-shaped structure enables the whole outer portion of the bottom ring 2 to be smooth and gradual and not easy to crack.
Further, the inner diameter of the top end of the bottom ring 2 is equal to the inner diameter of the bottom end of the bottom ring, so that the bottom ring 2 can be sleeved on the outer wall of the component in a cylindrical structure.
The specific outer diameter of the second annular middle ring 4 is equal to the outer diameter of the top end of the bottom ring 2, and the inner diameter of the second annular middle ring 4 is equal to the inner diameter of the top end of the bottom ring 2.
It is worth noting that the inner wall of the sealing ring body 1 is provided with anti-skid particles for increasing friction force, so that the friction force between the inner wall of the sealing ring body 1 and the outer wall of the corresponding component is increased.
It is worth to say that, the external diameter of the second ring-shaped middle ring 4 is larger than the external diameter of the top ring 5, and the internal diameter of the second ring-shaped middle ring 4 is equal to the internal diameter of the top ring 5, so that the diameters of the inner walls of the whole sealing ring body 1 are equal from top to bottom.
