Description

Technical Field

[0001] This utility model relates to the field of pipe fitting technology, and in particular to a rotary aviation pipe fitting. Background Technology

[0002] Rotary aviation pipe fittings are special fluid transfer devices designed specifically for the aviation and aerospace fields. They are used to achieve leak-free continuous transfer of media such as high-pressure gas, hydraulic oil, fuel oil, or coolant between rotating components and stationary pipelines. Their core function is to resolve the contradiction between mechanical rotation and fluid sealing, ensuring the reliability and safety of the system under dynamic operating conditions.

[0003] Existing aviation pipe fittings typically employ a fixed-length design. However, in practical applications, the piping layout in areas such as aircraft engine nacelles and wings is often very compact, and the installation spacing between pipes can vary significantly between different aircraft models or during later modifications. This variation can stem from various factors such as engine model changes, structural optimizations, or equipment upgrades. Traditional fixed-length pipe fittings, lacking adjustability, cannot accommodate these spacing variations, often necessitating custom-made pipes of specific lengths or the addition of extra adapters during installation. This not only increases design and manufacturing costs but also extends the modification cycle. Utility Model Content

[0004] The purpose of this invention is to provide a rotary aviation pipe fitting that can solve the problems mentioned in the background.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rotary aviation pipe connector, comprising a body, wherein an adjustment component is provided inside the body.

[0006] In a preferred embodiment, the adjusting assembly includes a sliding sleeve, two sliding rods are fixedly mounted on the outer surface of the main body, both sliding rods are slidably disposed inside the main body, a fixing plate is fixedly mounted inside the main body, a threaded rod is rotatably mounted inside the fixing plate, the threaded rod is hollow inside, one side of the threaded rod is threaded inside the sliding sleeve, a connecting tube is slidably disposed inside the threaded rod, and the connecting tube is fixedly mounted at the bottom of the sliding sleeve.

[0007] The technical effect of adopting the above-mentioned further solution is that by rotating the threaded rod, the sliding sleeve will move along the body, so that the connecting pipe fixedly installed inside the sliding sleeve will slide inside the threaded rod, thereby realizing the length adjustment.

[0008] In a preferred embodiment, a sealing ring is fixedly installed at one end of the connecting pipe.

[0009] The technical effect of adopting the above-mentioned further solution is that by setting a sealing ring, a sealed connection can be achieved between the connecting pipe and the threaded rod.

[0010] In a preferred embodiment, a connector is fixedly installed at one end of the sliding sleeve.

[0011] The technical advantage of adopting the above-mentioned further solution is that the connection of the device can be facilitated by the connector.

[0012] In a preferred embodiment, a limiting block is fixedly installed on the outer surface of the other end of the threaded rod, and a rotating component is rotatably embedded on the outer surface of the limiting block.

[0013] The technical effect of adopting the above-mentioned further solution is that one end of the threaded rod is embedded in the rotating part through a limiting block, thereby enabling the rotating part to rotate freely.

[0014] In a preferred embodiment, a knob is fixedly mounted on the outer surface of the threaded rod.

[0015] The technical advantage of adopting the above-mentioned further solution is that the threaded rod can be manually driven by a knob.

[0016] In a preferred embodiment, a slot is provided on one side of the outer surface of the body.

[0019] The technical advantage of adopting the above-mentioned further solution is that the threaded groove facilitates the installation of rotating parts.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In use, the screw rod rotates inside the main body by manually turning the knob. Since the sliding sleeve is threaded on the outer surface of the screw rod and is limited by the sliding rod, it can slide along the main body. When the sliding sleeve moves, the connecting pipe fixedly installed inside the sliding sleeve will move synchronously. The connecting pipe is slidably connected to the screw rod, thereby realizing the adjustment of the device length. Attached Figure Description

A connecting pipe 104 is slidably disposed inside the threaded rod 103. The connecting pipe 104 is fixedly installed at the bottom of the sliding sleeve 101. A sealing ring 105 is fixedly installed at one end of the connecting pipe 104. A connector (111) is fixedly installed at one end of the sliding sleeve 101. A limit block 110 is fixedly installed on the outer surface of the other end of the threaded rod 103. A rotating component 109 is rotatably embedded on the outer surface of the limit block 110. A knob 108 is fixedly installed on the outer surface of the threaded rod 103. A slot 107 is opened on one side of the outer surface of the body 100. A threaded groove is provided on the outer surface of the rotating component 109.

[0030] In this embodiment, during use, the internal knob 108 is first rotated through the slot 107. The knob 108 is fixedly connected to the threaded rod 103 inside the body 100. The threaded rod 103 is rotatably installed inside the body 100, thus driving the threaded rod 103 to rotate. The sliding sleeve 101 is threadedly installed on the outer surface of the threaded rod 103, and the sliding rod 106 on the outer surface of the threaded rod 103 is slidably engaged inside the body 100. Therefore, the sliding sleeve 101 is limited and can slide inside the body 100. The inside of the threaded rod 103 is hollow. With a clever design, the connecting pipe 104, which is fixedly installed inside the sliding sleeve 101, is slidably installed inside the threaded rod 103. The threaded rod 103 is in close contact with the connecting pipe 104. A sealing ring 105 is connected to the top of the connecting pipe 104. The sealing ring 105 can maintain the sealing between the threaded rod 103 and the connecting pipe 104. A limiting block 110 is fixedly installed at the other end of the threaded rod 103. The threaded rod 103 is rotated and locked inside the rotating part 109 through the limiting block 110, thereby enabling the rotating part 109 to rotate freely.

[0031] Working principle: In use, the internal knob 108 is rotated through the slot 107. The knob 108 is fixedly connected to the threaded rod 103 inside the body 100. The threaded rod 103 is rotatably installed inside the body 100, thus driving the threaded rod 103 to rotate. The sliding sleeve 101 is threaded onto the outer surface of the threaded rod 103, and the sliding rod 106 on the outer surface of the threaded rod 103 is slidably engaged inside the body 100. Therefore, the sliding sleeve 101 is limited and can slide within the body 100. The threaded rod 103 is hollow inside. In this design, the connecting pipe 104, which is fixedly installed inside the sliding sleeve 101, is slidably installed inside the threaded rod 103. The threaded rod 103 is in close contact with the connecting pipe 104. A sealing ring 105 is connected to the top of the connecting pipe 104. The sealing ring 105 can maintain the sealing between the threaded rod 103 and the connecting pipe 104. A limiting block 110 is fixedly installed at the other end of the threaded rod 103. The threaded rod 103 is rotated and locked inside the rotating part 109 through the limiting block 110, thereby enabling the rotating part 109 to rotate freely.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
