Technical Field
[0001] The utility model relates to the technical field of air-conditioning ducts, in particular to an adapter used for lengthening a bridge-mounted air-conditioning duct. Background Art
[0002] To reduce energy consumption, emissions, costs, and efficiency, aircraft docking uses bridge-mounted air conditioners (ACs) to replace the aircraft's APUs (Automated Puller Units) to provide air conditioning for the aircraft's onboard air conditioning. Currently, the ducting for the bridge-mounted ACs is fixed in length. After the jet bridge is vacated and before takeoff, the aircraft remains stationary for 30-60 minutes, according to takeoff procedures. During this time, the ducting for the bridge-mounted ACs is insufficient and cannot be connected to the onboard AC units. Consequently, the bridge-mounted ACs cannot replace the onboard AC units, resulting in significant economic downsides. Utility Model Content

Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.
[0036] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can refer to fixed connection, detachable connection, or integration; "connection" can refer to mechanical connection or electrical connection; it can refer to direct connection or indirect connection through an intermediate medium; it can refer to internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0037] See also Figures 1 to 4 The present invention provides an adapter for extending the air duct of a bridge-mounted air conditioner. The adapter includes a body 7, which specifically includes a first interface, a second interface, a handle 3 and a connecting hole 4.
[0038] The adapter can be connected to the air conditioning duct and the extension pipe of the bridge-mounted air conditioner, thereby extending the length of the bridge-mounted air conditioning duct.
[0039] Specifically, the adapter includes a first end face 1 and a second end face 6; the first end face 1 is provided with a first interface for connecting the bridge-mounted air-conditioning duct, and the second end face 6 is provided with a second interface for connecting the extension tube; a connecting hole 4 is opened in the adapter, and the connecting hole 4 connects the bridge-mounted air-conditioning duct and the extension tube.
[0040] The shape of the adapter and the connecting hole 4 are not limited. As long as the first end face 1 of the adapter can be connected to the bridge-mounted air conditioning duct, the second end face 6 can be connected to the extension tube, and the connecting hole 4 connects the bridge-mounted air conditioning duct and the extension tube to achieve the transmission of air-conditioning gas, the adapter can be disc-shaped, cylindrical, L-shaped, or other shapes that achieve the same effect. The corresponding connecting hole 4 can be straight or curved.
[0041] Specifically, such as Figure 1-Figure 5 In this example, a disc-shaped adapter is used. The disc-shaped body 7 is prone to rolling during operation and falling during transportation. This can be prevented from rolling by adding a flat portion to the body 7 or by changing its shape. In this example, the first end face 1 and the second end face 6 are the two end faces of a disc.
[0042] Preferably, in this embodiment, the first interface includes a plurality of jacks 2 evenly distributed around the axis of the disk, and the communicating hole 4 is formed with an opening at the center of the first end surface 1 .
[0043] Further, please combine Figure 5 In this embodiment, the first interface is used to connect the JB729 connector, and the JB729 connector is connected to the adapter by inserting the claw 83 into the jack 2 and then clamping it.
[0044] In a preferred embodiment, see Figure 5 By pulling the handle 81, the claws 83 are driven to clamp the body 7 and the connector body 82. The sealing ring 84 is deformed after being clamped, eliminating the gap between the body 7 and the connector body 82. Specifically, the structure of the JB729 connector is prior art and will not be described in detail here.
[0045] In this embodiment, there are four of the plurality of insertion holes 2 ; the four insertion holes 2 are evenly arranged around the opening of the communicating hole 4 on the first end surface 1 .
[0046] It is understood that in other embodiments of the present invention, this method can be used to adapt to other connectors of different sizes and models by changing the position and size of the jacks 2, thereby increasing the number of holes to make the adapter adaptable to more different plug models. It is also possible to provide multiple sets of jacks adapted to different connectors on the first end surface 1, so that a single adapter can be adapted to different connectors without having to replace the adapter.
[0047] Furthermore, the second interface includes a latching protrusion 5 provided on the outer circumferential side surface of the adapter and close to the second end surface 6 .
[0048] The clamping protrusion 5 is a rib protruding from the outer circular side surface.
[0049] The number of the ribs is two.
[0050] The second interface is used to connect to the extension tube. After connecting the adapter to the extension tube, a clamp is used to tightly connect the extension tube and the adapter using the protrusion 5 in the second interface. The outward protrusion 5 can be circular or have any other outward protrusion shape, and the number of protrusions 5 can be increased to ensure a more secure connection. In this example, the second interface is shown as only compatible with an extension tube of one diameter. In actual use, extension tubes of multiple diameters may be used. By adding a stepped structure with connectors of different sizes, it can be adapted to different diameters.
[0051] In a preferred embodiment, a handle 3 is provided on the outer circumferential side of the adapter. The handle 3 is a stainless steel sheet metal welded to the body 7. A standard cast handle can be used to improve ease of operation and reduce costs, a plastic handle can be used to reduce overall weight, or the handle can be fixed with screws and nuts.
[0052] The material of the adapter is 304 stainless steel.
[0053] Furthermore, the adapter is made of 304 stainless steel, which has the characteristics of slightly high cost and is not easy to mass-produce. The material of the adapter can be changed to Q235 steel, engineering plastics or composite materials, which can reduce production costs while not significantly reducing the corrosion resistance and mechanical properties of the adapter. Alternatively, 316 stainless steel can be used to give the adapter better mechanical properties.
[0054] It should be understood that the above description of the specific embodiments of the present invention is merely for the purpose of illustrating the technical approach and features of the present invention. Its purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. However, the present invention is not limited to the above-described specific embodiments. Any changes or modifications made within the scope of the claims of the present invention shall be included within the scope of protection of the present invention.
