Description

Technical Field

[0001] The utility model relates to the technical field of adapters, and particularly relates to a nylon landing gear adapter structure. Background Art

[0002] Landing gears are mainly commonly found in various flying devices, such as airplanes, drones or reconnaissance planes, etc., and are mainly used to enable the flying device to park smoothly on the ground. Nylon landing gears are more used on drones for the smooth parking of drones.

[0003] Common drone landing gears mainly rely on the telescopic movement of cylinders to drive the rotation of link mechanisms, thereby driving the rotation of wheels, so as to realize the lowering and retraction of the wheels. An adapter is required in the landing gear to achieve the pushing and rotating function to move the wheels.

[0004] However, when the wheels are slow to lower due to temporary failures or user problems, when the wheels contact the ground, it is easy to cause damage to the middle part of the adapter. Therefore, the adapter needs to be replaced. At present, most landing gears are connected by bolts and need to be disassembled as a whole for replacement, which is relatively inconvenient. For this reason, we propose a nylon landing gear adapter structure. Content of the Utility Model

[0005] The purpose of the utility model is to provide a nylon landing gear adapter structure. By setting a connection mechanism, it is convenient to use the cooperation of the connection sleeve 7 and the connection threaded column to realize the rapid replacement of the adapter body. At the same time, by using the cooperation of the protective sleeve, the docking component and the elastic component, good anti-misoperation performance is generated to avoid abnormal rotation of the connection sleeve and separation of the adapter body from the connection member.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A nylon landing gear adapter structure, including a landing gear body, a connection member arranged on the landing gear body, and an adapter body arranged on the side of the connection member.

[0009] A protective sleeve, which is sleeved on the outer surface of the connection sleeve. The protective sleeve is used to protect the connection sleeve. A docking component is arranged between the protective sleeve and the connection sleeve. An elastic component is arranged on one side of the protective sleeve. The protective sleeve is positioned by the cooperation of the docking component and the elastic component.

[0010] Preferably, the docking component includes an annular groove formed at the end of the protective sleeve, two clamping blocks fixedly connected to the inside of the annular groove, a fixing ring fixedly connected to the end of the connecting sleeve, clamping grooves formed on both sides of the fixing ring, and through grooves formed on the other two sides of the fixing ring.

[0011] Preferably, the elastic component includes a fixing sleeve fixedly connected to the end face of the protective sleeve, a connecting rod inserted into the fixing sleeve, a rotating ring fixedly connected to one end of the connecting rod, a connecting nut threadedly connected to the other end of the connecting rod, and a compression spring sleeved on the outer surface of the connecting rod, and the rotating ring is rotatably connected to the protective sleeve.

[0012] Preferably, an annular groove is formed on the outer surface of the connecting column, and the connecting column is sleeved with the connecting sleeve through the annular groove.

The connecting mechanism includes: a connecting threaded column 6, which is fixedly connected to the end of the connecting member 2; a connecting column 5, which is fixedly connected to the end of the adapter body 3, and a connecting sleeve 7 is sleeved on the outer surface of the connecting column 5, and the connecting sleeve 7 is threadedly connected to the connecting threaded column 6; a protective sleeve 8, which is sleeved on the outer surface of the connecting sleeve 7, and the protective sleeve 8 is used to protect the connecting sleeve 7. A docking assembly 4 is provided between the protective sleeve 8 and the connecting sleeve 7, and an elastic component 9 is provided on one side of the protective sleeve 8. The protective sleeve 8 is positioned through the cooperation of the docking assembly 4 and the elastic component 9; when it is necessary to disassemble the adapter body 3, by moving the protective sleeve 8, the protective sleeve 8 further connects the protective sleeve 8 and the connecting sleeve 7 through the cooperation of the docking assembly 4 and the elastic component 9, and then rotates the protective sleeve 8, so that the connecting sleeve 7 rotates until the connecting sleeve 7 is separated from the connecting threaded column 6. At this time, the adapter body 3 can be disassembled. Then, align the new adapter body 3 with the connecting member 2, and then reverse the protective sleeve 8 so that the connecting sleeve 7 is connected to the connecting threaded column 6. Subsequently, the protective sleeve 8 can be made not to be connected to the connecting sleeve 7 through the cooperation of the docking assembly 4 and the elastic component 9. At this time, even if the protective sleeve 8 is rotated, the connecting sleeve 7 will not rotate, having good anti-misoperation performance and improving the reliability of installation.

[0025] It should be further explained that the docking assembly 4 includes an annular groove 401 opened at the end of the protective sleeve 8, two clamping blocks 402 fixedly connected to the inside of the annular groove 401, a fixing ring 403 fixedly connected to the end of the connecting sleeve 7, clamping grooves 404 opened on both sides of the fixing ring 403, and through grooves 405 opened on the other two sides of the fixing ring 403; each through groove 405 penetrates the fixing ring 403, the internal cross-sectional profile size of the through groove 405 is larger than the external cross-sectional size of the corresponding clamping block 402, and the internal cross-sectional profile size of the clamping groove 404 is The elastic component 9 includes a fixed sleeve 901 fixedly connected to the end face of the protective sleeve 8, a connecting rod 902 plugged into the fixed sleeve 901, a rotating ring 903 fixedly connected to one end of the connecting rod 902, a connecting nut 905 threadedly connected to the other end of the connecting rod 902, and an extrusion spring 904 sleeved on the outer surface of the connecting rod 902, and the rotating ring 903 is rotatably connected to the protective sleeve 8; an annular cavity is opened at the end of the protective sleeve 8, and the protective sleeve 8 is connected to the rotating ring through the annular cavity. 903 is rotatably connected; by rotating the protective sleeve 8, the protective sleeve 8 drives the card block 402 to rotate, and at the same time, the protective sleeve 8 rotates along the rotating ring 903 until the card block 402 is aligned with the through slot 405, and then the protective sleeve 8 is moved so that the card block 402 passes through the through slot 405, and at the same time, the protective sleeve 8 drives the connecting rod 902 to move and compress the extrusion spring 904, and then the protective sleeve 8 is rotated 90 degrees to align the card block 402 with the card slot 404, and then the protective sleeve 8 is released, and the extrusion spring 904 slightly recovers its deformation, driving the card block 402 By engaging with the card slot 404, the protective sleeve 8 can then be rotated to drive the connecting sleeve 7 to rotate. When the protective sleeve 8 is no longer needed to drive the connecting sleeve 7 to rotate, the protective sleeve 8 is further moved to separate the card block 402 from the card slot 404, and then the protective sleeve 8 is rotated ninety degrees to align the card block 402 with the through slot 405, and then the protective sleeve 8 is released. At this time, the extrusion spring 904 recovers its deformation, so that the card block 402 moves out of the through slot 405. At this time, even if the protective sleeve 8 is rotated, the connecting sleeve 7 will not rotate, thereby producing good protection.

[0026] Furthermore, an annular groove is provided on the outer surface of the connecting column 5, and the connecting column 5 is connected to the connecting sleeve 7 through the annular groove; this facilitates the connecting sleeve 7 to rotate or move along the annular groove without being separated from the connecting column 5, and after installation, the connecting sleeve 7 can squeeze the side of the annular groove, thereby completely resisting the adapter body 3, making the connection more stable.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
