Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a connector for ultra-fine outer diameter copper air conditioning pipes. Background Technology

[0002] The pipes used in air conditioners mainly include copper pipes. Copper pipes are divided into red copper pipes and brass pipes according to their material. Red copper pipes have a better copper content, higher thermal conductivity, smaller pipe diameter, and are softer, making them easier to bend and deform. The disadvantage is that they are more expensive.

[0003] A search revealed application number CN202023004978.5, entitled "Quick Coupling for Air Conditioner Connecting Pipes." This application addresses the issue that current air conditioner connecting pipes require flaring the copper pipe before connecting it to the shut-off valve of the outdoor unit. This presents two problems during installation: firstly, it demands a high level of skill from the operator; secondly, it is slow. The quick coupling replaces the flaring of the copper pipe with a flaring plate, allowing installers to proceed directly without flaring, thus enabling faster installation and reducing the technical requirements. However, since the outer surface of copper pipes, especially thin copper pipes, is generally smooth, the connection method used in this application, while solving the flaring problem, still results in unstable locking due to the undeformed end of the copper pipe, affecting installation stability. Furthermore, the application still requires tools for installation, making it somewhat cumbersome. Further improvements are needed.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

The other end of the compression head has a bevel. An outer ring is threaded onto the outer wall of the fitting cylinder, and a bevel is formed on the inner bottom opening of the outer ring.

[0010] Furthermore, the bevels are arranged in a ring shape, and the slope of the bevels is the same as the slope of the inclined plane.

[0019] (1) This utility model adopts an extrusion head and an outer ring. When installing and connecting ultra-fine outer diameter copper air conditioning pipes, the connector cylinder can first be threaded into the air conditioning shut-off valve through the threaded port. Then, the ultra-fine outer diameter copper air conditioning pipe is inserted into the pipe groove. Then, the outer ring can be rotated.

[0028] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of this utility model, a connector for ultra-fine outer diameter copper air conditioning pipes is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, the ultra-fine outer diameter copper air conditioning pipe connector according to an embodiment of the present invention includes a connector cylinder 1 and an outer ring 6. A threaded opening 2 is provided on the top surface of the connector cylinder 1, and a channel 4 is provided inside the connector cylinder 1 through the threaded opening 2. A pipe groove 10 is provided on the outer side of the channel 4 below the threaded opening 2 and on the bottom surface of the connector cylinder 1. An annular groove 11 is provided on the inner wall of the pipe groove 10. The surface of the annular groove 11 is roughened to improve friction. A pressing head 8 is slidably connected through the side wall of the pipe groove 10, and a bevel 9 is provided at the other end of the pressing head 8. The outer ring 6 is threaded onto the outer wall of the connector cylinder 1, and a bevel 7 is provided at the bottom inner opening of the outer ring 6. The surfaces of the opening 9 and the bevel 7 are polished. When installing and connecting the ultra-fine outer diameter copper air conditioning pipe, the connector sleeve 1 can first be threaded into the air conditioning shut-off valve through the threaded opening 2. Then, the ultra-fine outer diameter copper air conditioning pipe is inserted into the pipe groove 10. Then, the outer ring 6 can be rotated. The outer ring 6 rotates and moves downward, pressing the bevel 7 downward through the inclined opening 9. The inclined opening 9 generates an inward thrust, pushing the extrusion head 8 inward to extrude the surface wall of the ultra-fine outer diameter copper air conditioning pipe. This deforms the surface wall of the ultra-fine outer diameter copper air conditioning pipe and puts it into the ring groove 11. The deformation improves the stability of the locking and effectively avoids slippage, thus improving the stability of the installation.

[0031] In one embodiment, the bevels 7 are arranged in a ring, and the slope of the bevels 7 is the same as that of the bevels 9, which facilitates the horizontal separation generated when the bevels 9 are pressed, thus pushing the extrusion head 8 inward.

[0032] In one embodiment, multiple sets of extrusion heads 8 are distributed at equal angles along the central axis of the connector cylinder 1, and the extrusion heads 8 are arranged corresponding to the annular groove 11, thereby improving the stability of extrusion deformation of ultra-fine outer diameter copper air conditioning pipes.

[0033] In one embodiment, a first sealing gasket 3 is fixedly bonded to the inner bottom surface of the threaded opening 2, and the threaded opening 2, the first sealing gasket 3, the connector cylinder 1 and the channel 4 are arranged coaxially to improve the stability of the installation.

[0034] In one embodiment, a second sealing gasket 12 is fixedly bonded to the top surface of the inner tube groove 10, and the tube groove 10 and the connector cylinder 1 are arranged coaxially. One end of the ultra-fine outer diameter copper air conditioning tube abuts against the second sealing gasket 12 to improve the sealing performance.

[0035] In one embodiment, the outer wall of the connector cylinder 1 is provided with an external thread 14, and the inner wall of the outer ring 6 is provided with an internal thread 15. The internal thread 15 and the external thread 14 are threadedly engaged, which is a common type of threaded connection.

[0036] In one embodiment, a first handle 5 is fixedly installed on the outer wall of the connector cylinder 1, and multiple first handles 5 are arranged. A second handle 13 is fixedly installed on the outer wall of the outer ring 6, and multiple second handles 13 are arranged. The operator can rotate the connector cylinder 1 by rotating the first handle 5 to facilitate connection with the shut-off valve of the air conditioner. Subsequently, the operator can rotate the outer ring 6 by rotating the second handle 13 to make the outer ring 6 rotate and move downward. The operator can complete the installation and disassembly by hand, which improves the convenience of use.

[0037] Working principle:

[0038] When installing and connecting ultra-fine outer diameter copper air conditioning pipes, the connector sleeve 1 can first be threaded into the air conditioning shut-off valve through the threaded port 2. Then, the ultra-fine outer diameter copper air conditioning pipe is inserted into the pipe groove 10. Subsequently, the outer ring 6 can be rotated, and the outer ring 6 rotates downward, pressing the inclined port 9 downward through the bevel 7. The inclined port 9 generates an inward thrust, pushing the extrusion head 8 inward to press the surface wall of the ultra-fine outer diameter copper air conditioning pipe, thereby deforming the surface wall of the ultra-fine outer diameter copper air conditioning pipe and entering the ring groove 11. The deformation improves the stability of the locking and effectively avoids slippage, thus improving the stability of the installation. At the same time, the operator can rotate the first handle 5 to drive the connector sleeve 1 to rotate, which facilitates the connection with the air conditioning shut-off valve. Subsequently, the operator can rotate the outer ring 6 through the second handle 13, causing the outer ring 6 to rotate downward. The operator can complete the installation and disassembly by hand, which improves the convenience of use.
