Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 4, the present invention provides a technical solution: the utility model provides a O type sealing washer with multiple sealed face effect, including seal structure 1, seal structure 1 includes sealing layer 15, through setting up annular protrusion 14, and interference fit can realize limiting displacement between annular protrusion 14 and the sealed article of needs, guarantee the stability of connecting, the surface of sealing layer 15 and the interior fixed surface of inflation stagnant water layer 11 are connected, the internal surface of sealing layer 15 and bearing structure 12's fixed surface fixed connection, the inside of sealing layer 15 is provided with two gas filled structure 13, two gas filled structure 13 set up the both sides at bearing structure 12 respectively, two gas filled structure 13 are located the inside upper and lower both sides of sealing layer 15 respectively.

Specifically, as shown in fig. 2, the surface of inflation stagnant water layer 11 is provided with annular arch 14, bearing structure 12 sets up to "X" shape, through setting up bearing structure 12, X shape structure through bearing structure 12, and then can have good enhancement support nature to sealing layer 15, prevent to warp, thereby life has been guaranteed, and be more favorable to in-service use simultaneously, the outside of inflation stagnant water layer 11 is provided with a plurality of V-arrangement structures, through setting up inflation stagnant water layer 11, and the V-arrangement structure through inflation stagnant water layer 11 can realize with the gomphosis of sealed article, not only can play good sealed effect, and can play the effect of location, prevent seal structure 1's displacement.
