Description

Technical Field

[0001] The present invention relates to a single-tube floating fluid connector. Background Art

[0002] Existing single-tube fluid connectors are usually designed with quick connectors. The quick connectors can be flexibly disassembled, assembled and maintained by connecting or separating a male connector and a female connector.

[0003] When assembling the quick connectors, a small amount of radial tolerance will be generated. In order to facilitate the quick alignment of the small amount of radial tolerance of the two connectors, at least one guide post is arranged beside the position where the connector is set adjacent to the cabinet body, and a guide sleeve is arranged at the position corresponding to the guide post on the side of the other connector. The guide sleeve has a guide hole. When assembling the quick connectors, first insert the guide post into the guide hole of the guide sleeve, and first guide the two originally slightly eccentric connectors to be close to coaxial and then smoothly dock.

[0004] However, when the docking eccentricity of the quick connectors is too large, it is impossible to guide and engage through the guide post and the guide seat. Therefore, how to provide a single-tube floating fluid connector with multiple compensations for non-coaxial eccentricity is actually the goal that those skilled in this art want to improve. Summary of the Invention

[0015] The following combines the drawings and embodiments to further describe the specific implementation manners of the present invention. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and cannot be used to limit the protection scope of the present invention.

[0016] The technical solution specifically implemented by the present invention is: As Figures 1 to 4As shown in the figure, a single-tube floating fluid connector includes: a mounting base 1, within which there is a receiving circular cavity 11. The receiving circular cavity 11 has an opening 12, which is located on one side of the mounting base 1. On the other side of the mounting base 1, there is a round hole 13, and the round hole 13 is coaxially connected and communicated with the receiving circular cavity 11; a rotating connecting pipe 2, which is inserted through the mounting base 1. The rotating connecting pipe 2 can axially displace, radially displace, and rotate within the receiving circular cavity 11. At the position of the opening 12 of the rotating connecting pipe 2, there is a mounting boss 21. Outside the mounting base 1 of the rotating connecting pipe 2, there is a limiting piece 22, and the limiting piece 22 axially abuts against the round hole 13; a floating seat 3, which is movably sleeved on the rotating connecting pipe 2. The floating seat 3 axially abuts against the mounting boss 21, and there is an adjustment gap between the mounting boss 21 and the floating seat 3. An elastic washer 33 is provided within the adjustment gap. There are axial and radial gaps between the floating seat 3 and the mounting base 1. On the floating seat 1, there is a guide sleeve 51 parallel to the rotating connecting pipe 2; an elastic connecting member 4, which is located within the mounting base 1. One end of the elastic connecting member 4 is fixedly connected to the mounting base 1, and the other end of the elastic connecting member 4 is fixedly connected to the floating seat 3.

[0017] The above-mentioned floating seat 3 has a limiting convex sleeve 31 and a connecting convex ring 32. Inside the limiting convex sleeve 31 and the connecting convex ring 32, there is an integrally formed stepped hole, and the stepped hole axially abuts against the mounting boss 21. The limiting convex sleeve 31 is located outside the mounting base 1, and there is an axial gap between the limiting convex sleeve 32 and the mounting base 1. The diameter of the limiting convex sleeve 31 is larger than the inner diameter of the opening 12, and the diameter of the connecting convex ring 32 is smaller than the inner diameter of the opening 12. There is a radial gap between the connecting convex ring 32 and the receiving circular cavity 11; specifically, there is a gap between the floating seat 3 and the mounting base 1 for the compensation of the first eccentricity, thereby initially reducing the docking eccentricity between the fixed pipe 7 and the rotating connecting pipe 2; there is a gap between the floating seat 3 and the rotating connecting pipe 2 for the compensation of the second eccentricity, thereby further reducing the docking eccentricity between the fixed pipe 7 and the rotating connecting pipe 2, making the connection between the fixed pipe 7 and the rotating connecting pipe 2 more convenient and smooth.

[0018] The above-mentioned elastic connecting member 3 is a conical spring. At both ends of the conical spring, there are plugs 41. Opposite jacks are opened on the receiving circular cavity 11 and the connecting convex ring 32, and the plugs 41 are inserted into the corresponding jacks; specifically, due to the characteristics of the conical spring 3, the floating seat 3 can return to the starting position when not under force, and the connection relationship of the conical spring 3 has a certain effect of limiting the rotation of the floating seat 3, enabling the floating seat 3 to rotate within a certain range.

[0019] One end of the above-mentioned adapter tube 2 adjacent to the floating seat 3 is provided with an insertion interface 23, and the insertion interface 23 is inserted into the fixed tube 7 on the cabinet body 6. The other end of the adapter tube 2 is provided with a hose joint 24.

[0020] The above-mentioned guide sleeve 51 is arranged on the limit boss 21. A guiding hole 52 is formed in the guide sleeve 51, and the guiding hole 52 is inserted into the guide post 5 on the cabinet body 6. The guide post 5 is parallel to the fixed tube 7.

[0021] During use, the fixed tube 7 and the guide post 5 are fixedly installed on the cabinet body 6 in parallel. First, align the guide post 5 with the guiding hole 52 of the guide sleeve 51. Due to the excessive docking eccentricity error of the quick connector, the insertion interface 23 of the fixed tube 7 and the adapter tube 2 cannot be aligned. During the process of gradually inserting the guide post 5 into the guiding hole 52, the fixed tube 7 abuts against the adapter tube 2, causing the adapter tube 2 and the floating seat 3 to have synchronous axial displacement. Through the insertion fit between the guide post 5 and the guide sleeve 51, the guide sleeve 51 drives the floating seat 3 to move slightly (the moving direction includes radial deflection or rotation). The adapter tube 2 follows the floating seat 3 to perform radial offset, and the adapter tube 2 is freely rotatable relative to the floating seat 3, thereby reducing the docking eccentricity between the fixed tube 7 and the adapter tube 2 and making the fixed tube 7 gradually align with the insertion interface 23 of the adapter tube 2. When the floating seat 3 abuts against the mounting seat 1 axially or radially, the first eccentricity compensation is completed. Then, the second eccentricity compensation is performed through the adjustment gap between the floating seat 3 and the adapter tube 2. The adapter tube 2 can be slightly inclined and freely rotated in the stepped hole of the floating seat 3, and the elastic washer 33 deforms, thereby further reducing the docking eccentricity between the fixed tube 7 and the adapter tube 2 and making the connection between the fixed tube 7 and the adapter tube 2 more convenient and smooth.

[0022] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
