Clamping ring with improved connecting structure
View Patent ↗A clamping ring includes first and second clamping ring members, each of which includes: a) an inner curved contour with a circumferential span of at least 90° that extends from a lower face to an upper face, the upper face being formed with an aperture for receiving therein a fastener for tightening the first and second clamping ring members towards each other, and b) an inner groove for receiving therein a seal. The first clamping ring member includes a first connecting member that extends circumferentially beyond the lower face. The second clamping ring member includes a second connecting member that couples the first connecting member with the second clamping ring member.
1. A clamping ring comprising:
first and second clamping ring members, each of which comprises: a) an inner curved contour that extends from a lower face to an upper face, said upper face being formed with an aperture for receiving therein a fastener for tightening said first and second clamping ring members towards each other, and b) an inner groove for receiving therein a seal;
said first clamping ring member comprising a first connecting member that extends circumferentially beyond said lower face; and
wherein said second clamping ring member comprises a second connecting member that couples said first connecting member with said second clamping ring member; and
wherein said first connecting member comprises a first male/female connector on a circumferential surface thereof, and wherein said second connecting member is formed with an opening through which said first connecting member is received and comprises a second male/female connector on a circumferential surface thereof, wherein said first and second male/female connectors engage each other when said first and second clamping ring members are tightened towards each other; and
wherein said opening through which said first connecting member is received is formed on a lug that protrudes outwards from said second clamping ring member.
2. The clamping ring according to claim 1 , wherein said second connecting member couples said first connecting member to an outer periphery of said second clamping ring member.
3. The clamping ring according to claim 1 , wherein said first male/female connector is formed on an inner circumferential surface of said first connecting member and said second male/female connector is formed on an outer circumferential surface of said second connecting member.
4. The clamping ring according to claim 1 , wherein said first connecting member comprises a stop that limits circumferential travel of said first connecting member through said opening.
5. The clamping ring according to claim 1 , wherein said first and second male/female connectors comprise teeth circumferentially spaced from one another.
6. The clamping ring according to claim 1 , wherein said second connecting member comprises a mechanical fastener which couples an end portion of said first connecting member to an outer periphery of said second clamping ring member.
7. A clamping ring comprising:
first and second clamping ring members, each of which comprises: a) an inner curved contour that extends from a lower face to an upper face, said upper face being formed with an aperture for receiving therein a fastener for tightening said first and second clamping ring members towards each other, and b) an inner groove for receiving therein a seal;
said first clamping ring member comprising a first connecting member that extends circumferentially beyond said lower face; and
wherein said second clamping ring member comprises a second connecting member that couples said first connecting member with said second clamping ring member, and wherein said first connecting member is coupled to said first clamping ring member with a mechanical fastener.
8. A clamping ring comprising:
first and second clamping ring members, each of which comprises: a) an inner curved contour that extends from a lower face to an upper face, said upper face being formed with an aperture for receiving therein a fastener for tightening said first and second clamping ring members towards each other, and b) an inner groove for receiving therein a seal;
said first clamping ring member comprising a first connecting member that extends circumferentially beyond said lower face; and
wherein said second clamping ring member comprises a second connecting member that couples said first connecting member with said second clamping ring member, and wherein said first connecting member is coupled to said first clamping ring member by being received in a lug formed with an opening through which said first connecting member is received.
9. The clamping ring according to claim 1 , wherein said lower faces of said first and second clamping ring members have flat portions that abut against each other when said first and second clamping ring members are tightened towards each other.
10. The clamping ring according to claim 1 , wherein one of said lower faces of said first and second clamping ring members has a rounded portion that does not abut against the other of said lower faces of said first and second clamping ring members when said first and second clamping ring members are tightened towards each other.
11. The clamping ring according to claim 1 , further comprising a fastener received in the apertures of said upper faces and a seal disposed in said inner grooves.
