Pressure relief structure for floating joint

Abstract

A pressure-reducing structure for a floating joint includes a fixed base, an adapter base, a sliding member, a retaining ring for holes, a sliding washer, and a spring. The fixed base has an open side, a closed side, and an accommodating space. The closed side has a through hole connecting to the accommodating space, and the accommodating space has an inner wall groove. The adapter has a first section and a second section extending toward the through holes on the open side and the closed side, respectively, and an axial abutment surface is provided between the first section and the second section. The sliding member has a base attached to the outer surface of the closed side, and a cylindrical body extending from the base passes through the through hole and connects to the second section of the adapter. The hole is fitted with a retaining ring in the inner wall groove, and a retaining ring abutment surface is parallel to and aligned with the axial abutment surface. The sliding pad is located on the outer periphery of the adapter, and a spring is provided between it and the closed side. This allows one side of the sliding pad to simultaneously abut against the retaining ring abutment surface and the axial abutment surface, providing additional support force through the retaining ring abutment surface to reduce the friction caused by radial sliding between the sliding pad and the adapter, and to improve the reliability of the joint after connection.

Claims

The connection includes a base flange that is radially slidably attached to the outer surface of the closed side; a retaining ring disposed within the accommodating space, having an outer ring portion embedded in the inner wall groove of the fixing seat, and a retaining ring abutting surface protruding from the inner wall groove of the fixing seat into the accommodating space, the retaining ring abutting surface facing the closed side and parallel to the axial abutting surface of the adapter seat; a sliding washer disposed within the accommodating space of the fixing seat and located on the outer periphery of the adapter seat, having a first side and a second side facing the open side and closed side of the fixing seat respectively, the first side abutting against the retaining ring abutting surface of the retaining ring and the axial abutting surface of the adapter seat; and a spring disposed within the accommodating space of the fixing seat and sleeved on the second section of the outer periphery of the adapter seat, one end of the spring abutting against the second side of the sliding washer, and the other end abutting against the inner surface of the closed side.

2. The pressure-reducing structure of the floating joint as described in claim 1, wherein the first section of the adapter is detachably connected to a quick connector.

3. The pressure-reducing structure of the floating joint as described in claim 1, wherein an elastic element is provided on the closed outer surface of the fixed seat.

4. The pressure-reducing structure of the floating joint as claimed in claim 1, wherein the cylinder of the sliding member has a front end and an end adjacent to the base, and the end is aligned with the inner circumferential surface of one end of the second segment of the adapter, and a sealing element is provided on the outer circumference of the end.

5. A pressure-reducing structure for a floating joint, comprising: a fixed seat having an open side and a closed side, the fixed seat having an accommodating space located between the open side and the closed side, the closed side having a through hole, and the fixed seat having an inner wall groove on the inner wall of the accommodating space; an adapter seat including a first section and a second section, the adapter seat being assembled with the fixed seat, the first section extending from the accommodating space toward the open side of the first end of the fixed seat, the second section extending from the accommodating space through the through hole of the closed side, and protruding through the through hole to the outside of the fixed seat, and the first section and the second section forming an axial abutment surface; a sliding member sleeved on the second section of the adapter seat from the outside of the closed side, and radially slidably attached to the outer surface of the closed side; and a fastener from the closed side... The second section of the adapter is externally fitted and adjacent to the sliding member; a retaining ring is disposed in the accommodating space, having an outer ring portion embedded in the inner wall groove of the fixing base, and a retaining ring abutment surface exposed in the accommodating space and facing the closed side of the fixing base, and the retaining ring abutment surface is parallel to and aligned with the axial abutment surface of the adapter; a sliding washer is disposed in the accommodating space of the fixing base and located on the outer periphery of the adapter, having a first side and a second side facing the open side and closed side of the fixing base respectively, and the first side abutting the retaining ring abutment surface of the retaining ring and the axial abutment surface of the adapter; a spring is disposed in the accommodating space of the fixing base and fitted on the outer periphery of the second section of the adapter, one end of the spring abutting the second side of the sliding washer, and the other end abutting the inner surface of the closed side.

6. The pressure-reducing structure of the floating joint as described in claim 5, wherein the first section of the adapter is detachably connected to a quick-connect coupling.

7. The pressure-reducing structure of the floating joint as described in claim 5, wherein an elastic element is provided on the closed outer surface of the fixed seat.

8. The floating connector pressure relief structure as described in claim 5, wherein the outer surface of the second section of the adapter is provided with an annular groove, and the fastener is embedded in the annular groove.
