Description

Technical Field

[0001] This utility model relates to air conditioning devices, and more particularly to split-type portable air conditioning devices. Background Technology

[0002] Traditional air conditioning units consist of an outdoor unit and an indoor unit. The outdoor unit includes a mounting plate, an upper rigid pipe, and a lower rigid pipe. One of the upper and lower rigid pipes is the refrigerant pipe, and the other is used to connect to the indoor unit. Before use, the upper and lower rigid pipes need to be connected.

[0003] However, the upper and lower rigid tubes are usually made of copper and are flexible. Connecting the two usually requires maintaining their positions while completing the connection, which is quite troublesome. Utility Model Content

[0004] One objective of this invention is to solve or alleviate the aforementioned technical problems.

[0005] The present invention provides an air conditioning unit comprising an outdoor unit, which includes a mounting plate, an upper rigid pipe, a lower rigid pipe, and a housing with an installation port. The installation port faces the mounting plate. The unit also includes a connecting structure and a fixing component. The connecting structure includes a connecting part, a movable connecting component, a connected part, and a fixed part. One of the connecting part and the connected part is fixedly connected to the upper rigid pipe, and the other is fixedly connected to the lower rigid pipe. The fixing component has a fixing hole and a positioning hole. The fixed part is embedded in the fixing hole, and the positioned part is embedded in the positioning hole. The fixing component is detachably connected to the mounting plate. The movable connecting component is sleeved on the connecting part and can rotate around the connecting part, and the movable connecting component is threadedly connected to the connected part. The fixing component is detachably fixedly connected to the mounting plate.

[0006] The advantage of this invention is that it eliminates the need to rotate the movable connector while maintaining the positions of the upper and lower rigid pipes to complete the installation, thus facilitating the connection between the upper and lower rigid pipes.

[0007] A further technical solution is provided where the connecting part has an outward protrusion and the movable connecting member has an inward protrusion; the outward protrusion of the connecting part and the inward protrusion of the movable connecting member abut against each other.

[0008] This technical solution can ensure a seal between the movable connector and the connected parts.

[0009] Further technical solutions also include a pipe connection structure, in which the connected part and the fixed part are integrally formed with the pipe connection structure, the pipe connection structure is threaded to the lower hard pipe, the fixed part is rotated and fixed relative to the fixing member, and when viewed from above, the positioning part is completely located inside the fixed part.

[0010] This technical solution enables the welding-free connection of copper pipes, which is convenient and can also improve the reliability of the connection between the upper and lower rigid pipes.

[0011] A further technical solution includes an extension portion extending into the connected portion; a sealing ring is fitted onto the extension portion; and the sealing ring is held between the inner wall of the connected portion and the extension portion.

[0012] This technical solution can further ensure the reliability of the connection between the upper rigid pipe and the lower rigid pipe.

[0013] A further technical solution involves making the fastener flexible.

[0014] This technical solution can ensure a seal between the movable connector and the connected parts.

[0015] A further technical solution is that the fastener is provided with a clamping gap that runs through the fastener in the thickness direction, and the clamping gap extends from the side wall of the fastener to the fixing hole and the positioning hole.

[0016] This technical solution allows for easy installation of the fixed part and the positioned part onto the fixing component.

[0017] A further technical solution involves tightening the gap by directing it from the exposed opening on the side wall of the fastener toward the mounting plate.

[0018] This technical solution can prevent the fixing part or the positioning part from detaching from the fastener after the fastener is installed on the mounting plate.

[0019] A further technical solution also includes fasteners, with mounting holes provided on both sides of the fastener; the fasteners pass through the mounting holes and are threadedly connected to the mounting plate, with the clamping gap located between the mounting holes on both sides of the fastener.

[0020] This technical solution ensures that the fixed part, the positioned part, and the fixing component are firmly connected and will not wobble.

[0021] A further technical solution is that a transverse reinforcing rib is provided on the side of the fastener opposite to the opening exposed from the side wall of the fastener in the clamping gap. There are two clamping gaps, and the reinforcing rib has a portion located between the two clamping gaps in the left-right direction.

[0022] This technical solution can improve the overall strength of the fastener while ensuring that the gap is reduced during the process of fixing the fastener to the mounting plate by rotating the fastener, thus ensuring that the fixed part, the positioned part and the fastener are firmly connected and will not wobble.

[0023] In a further technical solution, both the upper and lower rigid tubes are made of copper. Attached Figure Description

Detailed Implementation

[0032] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0033] As a specific embodiment, the air conditioning device of this utility model includes an outdoor unit 1, which includes a mounting plate 12, an upper rigid pipe 13, a lower rigid pipe 14, and a housing 11 with a mounting port 111. One of the upper rigid pipe 13 and the lower rigid pipe 14 is a refrigerant pipe, and the other is a pipe used to connect to the indoor unit (not shown in the attached drawings). Typically, both the upper rigid pipe 13 and the lower rigid pipe 14 are copper pipes.

[0034] The mounting port 111 is directly opposite the mounting plate 12, meaning that when the mounting port 111 is viewed directly, there is an overlap between the mounting plate 12 and the mounting port 111.

[0035] The air conditioning device of this utility model embodiment also includes a connecting structure 2 and a fixing member 3.

[0036] The connecting structure 2 includes a connecting part 21, a movable connecting member 22, a connected part 23, and a fixed part 24; one of the connecting part 21 and the connected part 23 is fixedly connected to the upper rigid tube 13, and the other is fixedly connected to the lower rigid tube 14.

[0037] The fastener 3 is provided with a fixing hole 34 and a positioning hole 341.

[0038] The fixed part 24 is embedded in the fixed hole 34, and the positioned part 241 is embedded in the positioned hole 341; the fastener 3 is detachably connected to the mounting plate 12.

[0039] The movable connector 22 is fitted onto the connecting part 21 and can rotate around the connecting part 21, and the movable connector 22 is threadedly connected to the connected part 23. Usually, the connected part 23 is a nut or the like; the cross-section of the fixed part 24 is a regular hexagonal structure, but of course, the cross-section of the fixed part 24 can also be other shapes.

[0040] The fastener 3 is detachably and fixedly connected to the mounting plate 12.

[0041] When installing an air conditioner, it is necessary to connect the outdoor unit 1 to the indoor unit, which means connecting the refrigerant pipe to the pipes of the indoor unit (not shown in the attached diagram), and connecting the upper rigid pipe 13 and the lower rigid pipe 14.

[0042] When connecting the upper rigid tube 13 and the lower rigid tube 14, fix the fixing member 3 on the mounting plate 12 to fix the position of the fixed part 24 and prevent it from resetting due to the elasticity of the upper rigid tube 13 or the lower rigid tube 14; then move the lower rigid tube 14 or the upper rigid tube 13 to align them, and rotate the movable connector 22 to connect it with the connected part 23 by threading it to complete the connection between the upper rigid tube 13 and the lower rigid tube 14; it is not necessary to rotate the movable connector 22 while maintaining the position of the upper rigid tube 13 and the lower rigid tube 14 to complete the installation, and the connection between the upper rigid tube 13 and the lower rigid tube 14 can be completed conveniently.

[0043] As one specific implementation, the connecting portion 21 is provided with an outward protrusion 211, for example, the outward protrusion 211 is annular when viewed from above; the movable connecting member 22 is provided with an inward protrusion 221; the outward protrusion 211 and the inward protrusion 221 abut against each other. The movable connecting member 22 is threadedly connected to the connected portion 23, causing the outward protrusion 211 to abut against the inward protrusion 221, thereby making the movable connecting member 22 tend to move away from the connected portion 23 and return to its original position, which can ensure the seal between the movable connecting member 22 and the connected portion 23.

[0044] As one specific implementation, the air conditioning device of this utility model embodiment further includes a pipe connection structure 4, with the connected part 23 and the fixed part 24 integrally formed with the pipe connection structure 4. The pipe connection structure 4 is threadedly connected to the lower rigid pipe 14. The fixed part 24 is rotated and fixed relative to the fixing member 3, and when viewed from above, the positioning part 241 is completely located within the fixed part 24. For example, the cross-section of the fixed part 24 is a regular hexagon or other non-circular shape and is embedded in the fixing hole 34, so that the fixed part 24 is rotated and fixed relative to the fixing member 3. The cross-section of the positioning part 241 is a circle with a diameter smaller than the inscribed circle of the regular hexagon of the fixed part 24. This implementation can achieve welding-free installation of copper pipes, etc., which is more convenient. Furthermore, the fixing member 3, in conjunction with the fixed part 24, can prevent the connected part 23 from rotating with the movable connecting member 22, preventing the connection between the upper rigid pipe 13 and the lower rigid pipe 14 from being incomplete, thereby improving the reliability of the connection between the upper rigid pipe 13 and the lower rigid pipe 14. Of course, the pipe connection structure 4 and the lower rigid pipe 14 can also be welded.

[0045] As one specific embodiment, the connecting part 21 is provided with an extension 212 that extends into the connected part 23; a sealing ring 25 is fitted onto the extension 212; the inner wall of the connected part 23 and the extension 212 clamp the sealing ring 25. This embodiment can further ensure the reliability of the connection between the upper rigid tube 13 and the lower rigid tube 14.

[0046] As one specific implementation, the fastener 3 is elastic. The fastener 3 allows the movable connector 22 to tend to return to its original position away from the connected portion 23, thereby ensuring a seal between the movable connector 22 and the connected portion 23.

[0047] As one specific implementation method, the fastener 3 is provided with a thickness direction ( Figure 6 The clamping gap 35 (shown in the vertical direction) penetrates through the fastener 3. For example, the fastener 3 is made of rubber and has elasticity. The clamping gap 35 extends from the side wall of the fastener 3 (it is easy to understand that the clamping gap 35 has an opening exposed from the side wall of the fastener 3) to the fixing hole 34 and the positioning hole 341. After the fixed part 24 and the positioning part 241 are inserted into the fixing hole 34 and the positioning hole 341 respectively through the clamping gap 35, the fastener 3 is reset, which can easily install the fixed part 24 and the positioning part 241 to the fastener 3.

[0048] As one specific embodiment, the compression gap 35 extends from the exposed opening on the side wall of the fastener 3 toward the mounting plate 12. This embodiment prevents the fastener 3 from being detached from the fastener 3 by the fastening part 24 or the positioning part 241 after it has been installed onto the mounting plate 12.

[0049] As one specific implementation, the air conditioning device of this utility model embodiment further includes a fastener 39. Mounting holes 31 are respectively provided on both sides of the fixing member 3. The fastener 39 passes through the mounting holes 31 and is threadedly connected to the mounting plate 12, so that the fixing member 3 and the mounting plate 12 are detachably fixedly connected. A compression gap 35 is located between the mounting holes 31 on both sides of the fixing member 3. During the process of rotating the fastener 39 to fix the fixing member 3 onto the mounting plate 12, the compression gap 35 narrows, causing the fixed part 24 and the positioned part 241 to be tightly fitted against the inner walls of the fixing hole 34 and the positioning hole 341, respectively, thereby ensuring that the fixed part 24 and the positioned part 241 are firmly connected to the fixing member 3 and will not wobble.

[0050] As one specific implementation, a transverse reinforcing rib 351 is provided on the side of the fastener 3 opposite to the opening of the clamping gap 35 exposed from the side wall of the fastener 3. There are two clamping gaps 35, and the reinforcing ribs 351 are in the left-right direction. Figure 4 The fastener 3 shown has a portion located between two clamping gaps 35 in the left-right direction. This embodiment can improve the overall strength of the fastener 3, while also ensuring that the clamping gaps 35 are reduced during the process of rotating the fastener 39 to fix the fastener 3 onto the mounting plate 12, ensuring that the fixed part 24, the positioned part 241 and the fastener 3 are firmly connected and will not wobble.
