The utility model is achieved by the following concrete technical means:
a floating seal ring comprises a seal ring, an outer ring locking flange and an inner ring locking flange; the sealing ring is provided with a corrugated ring, a plurality of outer edge fixing holes are uniformly distributed on the sealing ring at the outer side of the corrugated ring, and a plurality of inner edge fixing holes are uniformly distributed on the sealing ring at the inner side of the corrugated ring; a plurality of outer ring fixing holes are uniformly distributed on the outer ring locking flange and are correspondingly matched with the outer edge fixing holes; a plurality of inner ring fixing holes are uniformly distributed on the inner ring locking flange and are correspondingly matched with the inner edge fixing holes; the outer ring locking flange is positioned on the outer side of the corrugated ring, and the inner ring locking flange is positioned on the inner side of the corrugated ring.
Further, an outer ring clamping groove is formed in one side, attached to the sealing ring, of the outer ring locking flange, and the outer ring clamping groove is fixedly bonded with the outer edge of the sealing ring; and an inner ring clamping groove is formed in one side, attached to the sealing ring, of the inner ring locking flange, and the inner ring clamping groove is fixedly bonded with the inner edge of the sealing ring.
Furthermore, the outer ring fixing hole and the inner ring fixing hole are set to be counter bores, and the outer ring locking flange and the inner ring locking flange are chamfered at the edge of one side far away from the sealing ring.
Furthermore, the sealing ring is made of soft and elastic materials such as silica gel or rubber, and the shape of the sealing ring can be a polygon such as a circular ring or a rectangle.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses a set up the fold ring on the sealing ring, the fold ring is located between two parts of relative movement for the relative movement scope increase of two parts, through setting up outer lane locking flange and inner circle locking flange, be located the outside and the inboard of fold ring respectively, can play sealed effect with the fine terminal surface of fixing at two parts of sealing ring.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Examples
A floating seal ring is shown in figures 1-6 and comprises a seal ring 1, an outer ring locking flange 2 and an inner ring locking flange 3; the sealing ring 1 is provided with a corrugated ring 11, a plurality of outer edge fixing holes 12 are uniformly distributed on the sealing ring 1 at the outer side of the corrugated ring 11, and a plurality of inner edge fixing holes 13 are uniformly distributed on the sealing ring 1 at the inner side of the corrugated ring 11; a plurality of outer ring fixing holes 21 are uniformly distributed on the outer ring locking flange 2 and correspondingly matched with the outer edge fixing holes 12; a plurality of inner ring fixing holes 31 are uniformly distributed on the inner ring locking flange 3 and correspondingly matched with the inner edge fixing holes 13; the outer ring locking flange 2 is positioned on the outer side of the corrugated ring 11, and the inner ring locking flange 3 is positioned on the inner side of the corrugated ring 11.
Taking the cylindrical part 5 and the part 6 with the cylindrical hole as an example, the cylindrical part 6 is positioned in the cylindrical hole of the part 6 with the cylindrical hole, and the cylindrical part 5 and the part 6 with the cylindrical hole need to move relatively to a certain degree, when the end part needs to be sealed, firstly, the sealing ring 1 is attached to the end surface of the cylindrical part 5 and the part 6 with the cylindrical hole, the outer edge fixing hole 12 corresponds to the threaded hole on the end surface of the part 6 with the cylindrical hole, the inner edge fixing hole 13 corresponds to the threaded hole on the end surface of the cylindrical part 5, the fold ring 11 on the sealing ring 1 is clamped into the gap between the cylindrical part 5 and the part 6 with the cylindrical hole, then the outer ring fixing hole 21 on the outer ring locking flange 2 corresponds to the outer edge fixing hole 12, the inner ring fixing hole 31 on the inner ring locking flange 3 corresponds to the inner edge fixing hole 13, and the fastener 4 passes through the outer ring fixing hole 21, the outer edge fixing hole 12 and the inner ring fixing hole 31, The inward flange fixed orifices 13, and with cylinder part 5 with take the threaded hole connection on the cylinder hole part 6 terminal surface, so can fix sealing ring 1 at cylinder part 5 and take the terminal surface of cylinder hole part 6, fold ring 11 can take place to stretch out and draw back along with the removal of cylinder part 5, just so can prevent like the pollutant that "left side" shown in figure 6 from entering into "right side", reach sealed effect, and compare in prior art's sealing washer, the movable range increase of cylinder part 5.
An outer ring clamping groove 22 is formed in one side, attached to the sealing ring 1, of the outer ring locking flange 2, and the outer ring clamping groove 22 is fixedly bonded with the outer edge of the sealing ring 1; one side that inner circle locking flange 3 and sealing ring 1 laminated is equipped with inner circle draw-in groove 32, and inner circle draw-in groove 32 bonds fixedly with the inward flange of sealing ring 1, further improves sealed effect. The outer ring fixing hole 21 and the inner ring fixing hole 31 adopt counter bores, so that the head of the fastener 4 can sink into the counter bores, and the influence on the work is avoided.
Utilize technical scheme, or technical personnel in the field are in the utility model discloses under technical scheme's the inspiration, design similar technical scheme, and reach above-mentioned technological effect, all fall into the utility model discloses a protection scope.
