There is several and locating slot, the elastic packing hoop is located on mounting groove, is provided with convex on the elastic sealing ring inner wall
Column, the positioning convex column and locating slot is mating forms the limit that rotates to sealing ring, on the fixed part outside companion flange
Ring outer wall position is circumferentially formed with seal groove, and sealing lip is extended in the elastic packing circumferential direction seal groove, and the elasticity is close
Seal ring fracture is connected by connector and realizes elastic packing ring seal.
The beneficial effect being arranged in this way is: using the above scheme, sealing ring being arranged on the outer wall of flange outer ring, no longer
It is arranged between flange inner ring and flange outer ring, avoids sealing ring and occupy circumferential space, so that flange inner ring and flange outer ring
Between ball position distribution can be more reasonable, improve use using effect and service efficiency, be also more preferably easily installed, simultaneously
Seal groove is set in this way, equally there is preferable sealing effect, can effectively stop extraneous impurity.By positioning convex column and determine
Mating, the combination of realization elastic sealing ring and mounting groove of position slot, while elastic sealing ring fracture is arranged, so that elasticity is close
Seal ring can more convenient hoop be located on mounting groove, improve installation effectiveness, while using connector connect fracture site, be convenient for
It realizes elastic packing ring seal, introduced contaminants is avoided to enter, while ring structure is set in this way, be not easy phase in use
Outer ring is sent and is deflected, the using effect of bearing is improved.
The utility model is further arranged to the connector and is made of elastic material, and the connector both ends are provided with solid
Fixed button, elastic sealing ring fracture both ends are provided with bayonet, and the fixing buckle is fastened in bayonet and realizes to elastic sealing ring
Tension, be provided with sealing block between the connector and mounting groove.
The beneficial effect being arranged in this way is: using the above scheme, using this connection structure, structure is simply conducive to realize,
The tension of effective realisation sealing ring incision position, avoids getting loose, improves the using effect of product.
The utility model is further arranged to the bayonet and is multiple and is arranged at intervals on elastic sealing ring.
The beneficial effect being arranged in this way is: using the above scheme, multiple bayonets are set, to be adapted to the connection of different length,
The Adapter Property of product is improved, using effect is improved.
The utility model is further arranged to be extended with two closing lips on the connector into seal groove, two closing lips it
Between be formed with insertion groove for supplementing oil liquid.
The beneficial effect being arranged in this way is: using the above scheme, being arranged to this structure, convenient for supplement oil liquid, improves and produce
The using effect of product product.
