[0002] With the rapid development of drone technology, accurately measuring airspeed is crucial for ensuring stable flight and safe operation. Airspeed measurement typically relies on a pitot tube to obtain air pressure data outside the aircraft, which is crucial for the drone's flight control and navigation systems.

[0003] In practical applications, when a pitot tube needs to connect to a pitot tube and an air data sensor, it often spans a long internal space within the drone, preventing a straight connection. In such cases, a common solution is to install the pitot tube onto a double-ended pagoda adapter through an interference fit.

[0004] However, this existing solution has certain drawbacks. First, because the Pitot tube is made of a relatively soft material, repeated manual disassembly and assembly can easily damage it, affecting measurement accuracy and service life. Second, the interference fit prevents quick assembly and disassembly of the structure, making maintenance, repair, or replacement of components time-consuming and labor-intensive, reducing work efficiency.

[0036] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0037] Example 1

[0038] See also Figures 1 to 8The adapter provided by the embodiment of the present invention includes a first adapter component 10 and a second adapter component 20. The first adapter component 10 includes a first support base 11 and a first adapter tube 12, one end of the first adapter tube 12 can be passed through the first support base 11 and connected to the first support base 11, and the other end of the first adapter tube 12 can be detachably connected to the first tube body 101; the second adapter component 20 includes a second support base 21 and a second adapter tube 22, one end of the second adapter tube 22 can be passed through the second support base 21 and connected to the second support base 21, and the other end of the second adapter tube 22 can be detachably connected to the second tube body 102; the second support base 21 and the first support base 11 are detachably connected, and when the second support base 21 is connected to the first support base 11, one end of the first adapter tube 12 and one end of the second adapter tube 22 can be connected and communicate with each other.

[0039] When using the adapter proposed by the present invention, the first adapter component 10 is first fixed to the panel 100, and the first tube body 101 is connected to the other end of the first adapter tube 12. The second adapter component 20 serves as the free end. The operator connects the second support base 21 to the first support base 11 according to the on-site working conditions, and connects the second tube body 102 to the other end of the second adapter tube 22, thereby completing the transfer and connection between the first tube body 101 and the second tube body 102. The presence of the adapter converts the disassembly and assembly process of the first tube body 101 and the second tube body 102 into the disassembly and assembly process of the first adapter assembly 10 and the second adapter assembly 20, avoiding the shortening of the tube life due to repeated disassembly and assembly of the tube body; and, due to the presence of the first support seat 11 and the second support seat 21, it can be fixed to the internal structure of the drone, which has the advantages of reducing shaking, reducing pipeline wear, and facilitating sealing of the surrounding structure of the pipeline compared to the traditional non-fixed method (direct interference fit); in addition, the separation of the tube body no longer involves the disassembly and assembly of the tube body, but is converted into an adapter structure, which is conducive to rapid disassembly and assembly, and can be used for rapid disassembly of the drone structure, thereby improving the efficiency of disassembly and assembly.

[0040] It is understandable that in other embodiments, the second adapter component 20 may be fixed to the panel 100 , and the first adapter component 10 may serve as a free end, which is not limited here.

[0041] In this embodiment, the first tube body 101 and the second tube body 102 are both Pitot tubes. In other embodiments, the first tube body 101 and the second tube body 102 can be other types of pipes for gas or liquid transmission, such as pressure measuring tubes, ventilation tubes, etc. The specific type depends on the actual application scenario and requirements and is not limited here.

[0042] The specific structure of the adapter is described below.

[0043] The first support base 11 includes an integrally formed first fixing plate 111 and a first support frame 112. One end of the first transfer tube 12 can pass through the first fixing plate 111 and enter the first support frame 112. The second support base 21 includes a second fixing plate 211 and a second support frame 212. One end of the second transfer tube 22 can pass through the second fixing plate 211 and enter the second support frame 212. One of the first support frame 112 and the second support frame 212 can be sleeved on the other. One of the first transfer tube 12 and the second transfer tube 22 can be inserted into the other. The integrally formed design improves the stability of the first support base 11 and the second support base 21. The design of the first support frame 112 and the second support frame 212 being sleeved on each other makes the adapter more convenient and quick to assemble and disassemble, without the need for complicated operating steps and tools, reducing maintenance costs and time. In addition, the first support frame 112 and the second support frame 212 can also guide each other to facilitate the sleeved process. The design of the first transfer tube 12 and the second transfer tube 22 being inserted into each other makes the connection of the adapter tighter and more precise, effectively reducing the risk of gas or liquid leakage during the transmission process, and improving the transmission efficiency and measurement accuracy.

[0044] The first adapter tube 12 is inserted through and engaged with the first fixing plate 111, while the second adapter tube 22 is inserted through and engaged with the second fixing plate 211, thereby improving the stability of the connection. In other embodiments, the first adapter tube 12 and the first fixing plate, and the second adapter tube 22 and the second fixing plate 211, can also be connected by threaded connections, riveted connections, etc., which are not limited here.

[0045] It is worth noting that the first support frame 112 can be mounted on the second support frame 212, or the second support frame 212 can be mounted on the first support frame 112; the first transfer tube 12 can be inserted into the second transfer tube 22, or the second transfer tube 22 can be inserted into the first transfer tube 12, and no limitation is made here.

[0046] To facilitate securing the first adapter assembly 10 to the panel 100, the first fixing plate 111 is provided with mounting holes 1111, symmetrically located on either side of the first fixing plate 111. The symmetrical design of the mounting holes 1111 ensures more even force distribution during the securing process, effectively preventing tilting or instability of the first adapter assembly 10 due to uneven force distribution. During use, the first adapter assembly 10 is secured to the panel 100 by inserting bolts or screws through the mounting holes 1111 and connecting them to the panel 100.

[0047] To further enhance the stability of the first support frame 112 and the second support frame 212 after they are mounted, a buckle 15 is provided on the first support frame 112. A limiting protrusion 151 is formed on the inner side of the buckle 15, and the limiting protrusion 151 can be engaged with the second fixing plate 211. The engaging structure of the buckle 15 effectively prevents relative displacement between the first adapter assembly 10 and the second adapter assembly 20 due to factors such as drone vibration during use, ensuring a secure connection of the adapter. This ensures that the adapter assembly will not become loose or leak in the vibration environment of drone flight, thereby improving the reliability and safety of transmission. When the first adapter assembly 10 and the second adapter assembly 20 need to be disassembled, the buckle 15 can be released by simply pulling the buckle 15 outward to move the limiting protrusion 151 away from the second fixing plate 211, thereby releasing the lock of the buckle 15 and completing the separation of the first adapter assembly 10 and the second adapter assembly 20.

[0048] In other embodiments, a buckle 15 may be provided on the second support frame 212 , and the limiting protrusion 151 may be engaged with the first fixing plate 111 . This is not limited here, and it is only necessary to ensure that the limiting effect of the first adapter component 10 and the second adapter component 20 is achieved through the buckle 15 .

[0049] Specifically, two clips 15 are provided, symmetrically positioned on opposite sides of the first support frame 112, further enhancing the stability and balance of the first and second support frames 112, 212 after they are nested. This ensures a more even clamping force on the first and second support frames 112, 212, effectively preventing local deformation or loosening due to uneven force, thereby comprehensively ensuring the stability of the connection. In actual use, the two symmetrical clips 15 can better resist external forces from all directions, reducing the risk of displacement or detachment of the adapter.

[0050] In order to improve the sealing performance of the adapter, a first sealing ring 13 is provided on the outer periphery of the first adapter tube 12; and / or a second sealing ring 23 is provided on the outer periphery of the second adapter tube 22. The sealing ring can effectively fill the tiny gap between the first adapter tube 12 or the second adapter tube 22 and the connecting component, thereby improving the sealing performance of the adapter at the connecting portion. It prevents gas or liquid from leaking from the connection during the transmission process, thereby ensuring the efficiency and accuracy of the transmission. Specifically, in this embodiment, the first sealing ring 13 is provided on the outer periphery of the first adapter tube 12 and is arranged in the first support frame 112 and is bonded to the first fixed plate 111. The second sealing ring 23 is provided on the outer periphery of the second adapter tube 22 and is arranged in the second support frame 212 and is bonded to the second fixed plate 211.

[0051] In this embodiment, the first sealing ring 13 and the second sealing ring 23 are both made of silicone sealing gaskets, which are bonded to the first fixing plate 111 and the second fixing plate 211. In other embodiments, rubber sealing rings may also be used, which is not limited here.

[0052] During use, to prevent the first adapter tube 12 or the second adapter tube 22 from being disengaged from the first support seat 11 or the second support seat 21 due to force applied during flight vibrations of the drone, the first adapter tube 12 is provided with a first retaining ring 14 on its outer periphery, which abuts the first support seat 11, and / or the second adapter tube 22 is provided with a second retaining ring 24 on its outer periphery, which abuts the second support seat 21. The provision of the first retaining ring 14 and the second retaining ring 24 effectively positions the first adapter tube 12 and the second adapter tube 22 in the axial direction, preventing unnecessary axial displacement during operation, thereby ensuring the stability and reliability of the connection. Whether the first retaining ring 14 or the second retaining ring 24 is provided alone, or both are provided simultaneously, flexible adjustments can be made according to actual needs, enhancing the applicability and versatility of the adapter.

[0053] Specifically, the other end of the first adapter tube 12 is configured in a pagoda shape, and / or the other end of the second adapter tube 22 is configured in a pagoda shape. The pagoda-shaped tube body increases the contact area between the first and second adapter tubes 12, 22 and the first and second tube bodies 101, 102, thereby improving the tightness and stability of the connection. Furthermore, the pagoda-shaped design helps disperse pressure at the connection point, reducing stress concentration and thus extending the service life of the adapter tube and tube body. It will be appreciated that the pagoda-shaped tube body is a common tube body shape in the art, and its specific structure and operating principle will not be described in detail here.

[0054] More specifically, the other end of the first adapter tube 12 and the other end of the second adapter tube 22 have the same inner diameter, which improves the versatility of the adapter, facilitates manufacturing and quality control, and reduces production costs and process difficulty.

[0055] Example 2

[0056] The embodiment of the present invention also provides a pitot tube, including an adapter and at least two tube bodies, wherein two adjacent tube bodies are connected by the adapter. Since the adapter has the characteristics of detachability and stable connection, the pitot tube is more convenient to assemble and maintain. A damaged tube body or adapter part can be easily replaced, reducing maintenance costs and time. Secondly, the good sealing performance of the adapter ensures the accuracy of gas or liquid transmission during the measurement process of the pitot tube, reduces measurement errors caused by leakage, and improves measurement accuracy. In addition, the flexible connection method of the adapter enables the pitot tube to adapt to different installation conditions and space requirements, increasing its applicability in various application scenarios.

[0057] The following describes the assembly process of the adapter.

[0058] The assembly sequence of the first adapter is as follows: pass the first adapter tube 12 through the first fixing plate 111, and allow one end of the first adapter tube 12 to enter the first support frame 112. Then, set a retaining ring on one side of the first fixing plate 111 to fix the first adapter tube 12 to prevent it from falling off; then, adhere the first sealing ring 13 to the internal groove of the first support frame 112, and allow the first sealing ring 13 to be sleeved on the first adapter tube 12, thereby ensuring the airtightness of the first adapter tube 12.

[0059] The assembly sequence of the second adapter is as follows: pass the second adapter tube 22 through the second fixing plate 211, and make one end of the second adapter tube 22 enter the second support frame 212; then, set a retaining ring on one side of the second fixing plate 211 to fix the second adapter tube 22 to prevent it from falling off; then, glue the second sealing ring 23 to the inner groove of the second support frame 212, and make the second sealing ring 23 be sleeved on the second adapter tube 22, so as to ensure the airtightness of the second adapter tube 22.

[0060] The assembly sequence of the adapter is as follows: fix the first fixing plate 111 to the panel 100 with screws, and the second adapter component 20 is the free end. The operator holds it and aligns the second adapter tube 22 with the first adapter tube 12, and inserts them into each other. After that, the second support frame 212 is inserted into the first support frame 112, and the limiting protrusion 151 of the buckle 15 on the first support frame 112 is abutted against the second fixing plate 211 to ensure that the adapter is not easy to loosen; when disassembly is required, the buckle 15 can be unlocked by pushing the buckle 15 outward to complete the separation of the first adapter component 10 and the second adapter component 20.

[0061] The above embodiments merely illustrate the basic principles and features of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications are possible without departing from the spirit and scope of the present invention. Such changes and modifications are within the scope of the present invention.
