Floating joint structure

Abstract

A floating connector structure includes a fixed base, a resetting member, an elastic member, and a connector fitting. The fixed base includes a base body, a receiving groove, and a through hole. The through hole and the receiving groove are located on two opposite sides of the base body and are interconnected. The resetting member is movably located within the receiving groove and has a pressure-bearing inclined surface. The elastic member elastically abuts against the base body and the resetting member. The connector fitting includes a pipe body and a pressure member. The pipe body is located within the receiving groove and the through hole, with a gap between the pipe body and the inner wall of the through hole. The pressure member is located within the receiving groove and is sleeved onto the pipe body. The pressure member has a pressure-applying inclined surface. The pressure-applying inclined surface of the pressure member and the pressure-bearing inclined surface of the resetting member are externally matched, and the pressure-applying inclined surface is slidably connected to the pressure-bearing inclined surface.

Claims

1. A floating joint structure, comprising: A fixed base includes a body, a receiving groove, and a through hole. The body includes a first surface and a second surface arranged opposite to each other. The receiving groove is located on the first surface of the body, and the through hole is located on the second surface of the body and communicates with the receiving groove. A resetting member is movably located within the receiving groove and has a pressure-receiving inclined surface. An elastic member elastically abuts against the body and the resetting member respectively. A connector pipe includes a pipe body and a pressing member. The pipe body is located within the receiving groove and the through hole, and a gap is separated between the pipe body and the inner wall of the through hole. The pressing member is located within the receiving groove and is sleeved onto the pipe body. The pressing member has a pressure-applying inclined surface, which matches the pressure-receiving inclined surface in shape, and the pressure-applying inclined surface is slidably connected to the pressure-receiving inclined surface.

2. The floating connector structure as described in claim 1, wherein the pipeline body comprises: a front pipe section located within the receiving groove and the through hole; a joint located at one end of the front pipe section; an abutment flange located on the joint; and a spring element that elastically abuts against the abutment flange and the pressure member, respectively.

3. The floating joint structure as described in claim 2, wherein the pressure member comprises: a disc body circumferentially fitted onto the front pipe section; a through channel axially extending through the disc body and accommodating a portion of the front pipe section; and a tapered convex surface located on one side of the disc body opposite the joint, wherein the tapered convex surface is the pressure ramp.

4. The floating connector structure as described in claim 3, wherein the reset member comprises: an annular body surrounding the pipeline body and the compression member; a through-hole axially extending through the annular body and accommodating the disc; and a conical concave surface located on one side of the annular body opposite to the elastic member and connected to the through-hole, wherein the conical concave surface is the pressure-bearing slope.

5. The floating connector structure as described in claim 3, wherein the connector further comprises: a fixed bushing including a sleeve fitted onto the front pipe section, including a front sleeve portion and a rear sleeve portion arranged sequentially, the front sleeve portion being located within the through hole and the receiving groove, and the rear sleeve portion being located outside the receiving groove.

6. The floating joint structure as described in claim 5, wherein a gap is formed between the front pipe section and the sleeve, the long axis of the gap being parallel to the long axis of the joint fitting; and the fixed bushing is further provided with an elastic ring, the elastic ring being fixedly located on the inner wall of the rear sleeve and being sleeved around the front pipe section.

7. The floating joint structure as described in claim 5, wherein the pressing member further includes an abutment portion located within the through channel and abutting against one end of the front sleeve portion relative to the rear sleeve portion, and a gap is formed between the front tube section and the abutment portion.

8. The floating connector structure as claimed in claim 5, wherein the fixed bushing further includes: a recess located on the rear sleeve; and the pipeline body further includes a rear pipe section and a sleeve located at one end of the rear pipe section and removably sleeved to the other end of the front pipe section, the sleeve having a protrusion that removably engages the recess.

9. The floating connector structure as described in claim 8, wherein the recess has a first guide slope and the protrusion has a second guide slope, the first guide slope and the second guide slope are matched in shape, and the first guide slope is slidably connected to the second guide slope.

10. The floating connector structure as described in claim 9, wherein the first guide ramp includes a conical concave surface and the second guide ramp includes a conical convex surface.

11. The floating connector structure as described in claim 5, wherein the connector further includes a retaining washer fitted on the front pipe section and located within the receiving groove, and slidably located at the bottom of the receiving groove; and the retaining bushing further includes a covering flange protruding from the outer surface of the sleeve, located between the front sleeve portion and the rear sleeve portion, surrounding the front pipe section, and slidably located on the second surface of the base.

12. The floating connector structure as described in claim 11, wherein the pressing member further includes an extension located on one side of the disc facing the through hole, circumferentially fitted onto the front tube section, and respectively connecting the tapered convex surface and the fixing washer, wherein the through channel passes through the disc and the extension, and the front sleeve is located within the through channel and sandwiched between the extension and the front tube section.

13. The floating joint structure as described in claim 12, wherein the pressing member further includes an annular groove and an annular flange, the annular groove being radially recessed on the extension and located on one side of the extension opposite to the through channel, and the annular flange being formed at the bottom of the annular groove, wherein the annular groove and the annular flange are coaxial with each other and both surround the axis of the through channel, wherein a portion of the retaining washer is received in the annular groove and directly abuts against the annular flange and the extension, and another portion of it directly abuts against the bottom of the receiving groove.

14. The floating connector structure as claimed in claim 1, wherein the fixing seat further comprises: an annular groove located on the inner wall of the receiving groove; and a limiting ring fixed in the annular groove and abutting against the reset member, thereby limiting the reset member to be located in the receiving groove.
