Description

Technical Field

[0001] This utility model belongs to the field of landing gear technology, and in particular relates to a landing gear installation structure that is easy to maintain. Background Technology

[0002] In the current context of the rapid development of the civil aviation transportation industry, the aircraft landing gear, as one of the core subsystems for ensuring flight safety, is a key load-bearing interface connecting the landing gear struts and the aircraft body. It bears multiple complex forces such as landing impact loads, taxiing vibrations, and static support. Its structural reliability and ease of maintenance are directly related to the operational efficiency and flight safety of the aircraft.

[0003] However, the existing landing gear is inconvenient to install and the operation process is relatively complicated. This not only hinders the subsequent inspection and maintenance work and affects maintenance efficiency, but also reduces the reliability and safety of the landing gear installation structure in the long term. Utility Model Content

[0004] The purpose of this utility model is to provide a landing gear installation structure that is easy to maintain. By setting a locking part, it solves the problem that the existing landing gear is inconvenient to install and has a complicated operation process, which not only hinders the subsequent inspection and maintenance work and affects maintenance efficiency, but also reduces the reliability and safety of the landing gear installation structure in the long term.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a landing gear mounting structure that is easy to maintain. It includes a connecting frame, a sliding rod on the right side of the connecting frame, a threaded groove on the front side of the sliding rod, a threaded rod threaded to the inner wall of the threaded groove, and a hexagonal abutment rotatably connected to the outer wall of the threaded rod. A circular block is fixedly connected to the rear side of the hexagonal abutment. Two expansion parts are respectively mounted on the two sliding rods, and a handle is fixedly connected to the front side of the threaded rod. The handle is used to rotate the threaded rod. The locking assembly passes through the sliding rod through the perforated fixing block and the perforated hollow mounting block. The rotation of the threaded rod drives the hexagonal abutment to move, achieving a tight locking of the perforated hollow mounting block. Simultaneously, the handle allows for reverse operation to release the locking mechanism, providing a basis for landing gear installation, fixing, and subsequent maintenance and disassembly.

[0006] Furthermore, the slide bar is provided with several rectangular guide grooves, and rectangular sliders are slidably connected to the inner walls of the several rectangular guide grooves. Rectangular slide rods are fixedly connected to the front sides of the several rectangular sliders, and the front sides of the several rectangular slide rods respectively extend slidably out of the several rectangular guide grooves. The front sides of the several rectangular slide rods are fixedly connected to the circular blocks. The guide assembly uses the sliding cooperation of the rectangular guide grooves, rectangular sliders and rectangular slide rods to provide stable guidance for the movement of the hexagonal abutment and the circular block in the locking assembly, and prevents them from deviating during the locking process.

[0007] Furthermore, the connecting frame is equipped with two landing gears. Two perforated fixing blocks pass through the left and right sides of the connecting frame. The outer walls of several perforated fixing blocks are provided with perforated hollow mounting blocks. The tops of the two landing gears are respectively fixedly connected to several perforated hollow mounting blocks. The outer walls of several perforated fixing blocks contact the inner walls of several perforated hollow mounting blocks. The sliding rod passes through the perforated fixing block and the perforated hollow mounting block located at the left rear and contacts the inner wall.

[0008] Furthermore, a cylindrical groove is provided on the rear side of the slide rod, and an installation block is fixedly connected to the inner wall of the front side of the cylindrical groove. Two spring grooves are provided on the installation block. The two spring grooves are mirror images of each other. The installation assembly provides installation space and structural support for the spring telescopic rod, locking block and other components of the expansion assembly by providing a cylindrical groove on the rear side of the slide rod and setting an installation block with spring grooves. This is the basis for the expansion assembly to realize its function.

[0009] Furthermore, a spring telescopic rod is fixedly connected to the inner wall of the two spring grooves on the side closest to each other, and a locking block is fixedly connected to the side of the two spring telescopic rods on the side furthest from each other. Two sliding grooves are opened on the inner wall of the cylindrical groove, and a lever is fixedly connected to the rear side of the two locking blocks. The two locking blocks slide out of the cylindrical groove through the two sliding grooves respectively. The expansion assembly pushes the locking blocks out of the cylindrical groove by the spring telescopic rod. After the sliding rod passes through the relevant components, it achieves preliminary anti-drop positioning. Pressing the lever can retract the locking blocks to complete the insertion or removal of the sliding rod, which helps to facilitate the installation and removal of the landing gear.

[0010] This utility model has the following beneficial effects: 1. By incorporating a locking mechanism, during installation, the locking assembly, through a sliding rod passing through the perforated fixing block and the perforated hollow mounting block, and in conjunction with the rotation of the threaded rod, moves the hexagonal abutment block, effectively securing the perforated hollow mounting block and preventing loosening after installation. The guide assembly, through the sliding cooperation of rectangular guide grooves, rectangular sliders, and rectangular sliding rods, provides stable guidance for the movement of the hexagonal abutment block and the circular block. Furthermore, during disassembly and maintenance, the locking state can be released simply by rotating the handle in the opposite direction, significantly simplifying the operation process and facilitating subsequent inspection and maintenance of the landing gear. This effectively improves maintenance efficiency and ensures the long-term reliability and safety of the landing gear installation structure. 2. By incorporating an expansion section, during installation and maintenance, the mounting assembly provides a reasonable space and structural foundation for installation by creating a cylindrical groove on the rear side of the slide rod and installing a mounting block with a spring groove. In its natural state, the spring telescopic rod in the expansion assembly pushes the locking block out of the cylindrical groove. When the slide rod passes through the perforated fixing block and the perforated hollow mounting block, the locking block locks in the corresponding position, effectively preventing the slide rod from accidentally falling off and achieving initial fixation. During installation, pressing the lever allows the locking block to retract into the slide groove without affecting the slide rod's insertion operation. For disassembly, pressing the lever again allows the slide rod to be pulled out, further improving the convenience of landing gear installation and disassembly. Combined with the locking mechanism, this forms a double guarantee, ensuring structural stability after installation and providing convenience for maintenance.

By setting the locking part 2, the operation process is greatly simplified, which provides convenience for the subsequent inspection and maintenance of landing gear 112, effectively improves maintenance efficiency, and ensures the reliability and safety of the landing gear installation structure for long-term use.

[0018] The expansion part 3 includes a cylindrical groove 311 located on the rear side of the slide rod 211. A mounting block 312 is fixedly connected to the inner wall of the front side of the cylindrical groove 311. Two spring grooves 313 are provided on the mounting block 312. The two spring grooves 313 are mirror images of each other. A spring telescopic rod 321 is fixedly connected to the inner wall of the two spring grooves 313 on the side closer to each other. A locking block 322 is fixedly connected to the side of the two spring telescopic rods 321 on the side farther from each other.

It forms a double guarantee with the locking part 2, which not only ensures the structural stability after installation, but also provides convenience for maintenance.

[0019] A specific application of this embodiment is as follows: In use, the connecting frame 111 should be installed on the drone. When installing the landing gear 112, two hollow mounting blocks 114 with openings are respectively inserted into the fixed blocks 113 with openings on one side of the connecting frame 111. Then, the sliding rod 211 is passed through the holes on the two fixed blocks 113 with openings and the hollow mounting blocks 114 with openings. Before passing through, the two locking blocks 322 are pressed to bring them close to the mounting block 312. At the same time, the spring telescopic rods 321 in the two cylindrical grooves 311 are compressed until the two locking blocks 322 are retracted into the two sliding grooves 323. After the two locking blocks 322 enter the holes on the front hollow mounting block 114 with openings, the two locking blocks 322 are released. After passing through the holes on the front fixed blocks 113 with openings and the hollow mounting blocks 114 with openings, the two spring telescopic rods 321 rebound, causing the two locking blocks 322 to move away from the mounting block 312 and reset, thereby preventing the sliding rod 211 from passing through the front fixed blocks 113 with openings and the hollow mounting blocks 114 with openings. After the two locking blocks 322 pass through the rear-hole fixing block 113 and the hollow mounting block 114, pinch the sliding rod 211 to prevent it from rotating. Then turn the handle 216. The handle 216 will drive the threaded rod 213 to rotate on the inner wall of the threaded groove 212. During this process, the hexagonal abutment 214 will approach the two locking blocks 322 until the rear side of the two locking blocks 322 abuts against the rear-hole hollow mounting block 114. The circular block 21... 5. The hollow mounting block 114 is inserted into the hole of the front side opening and the hexagonal abutment block 214 is abutted by the front side opening hollow mounting block 114, thus completing the fixation of the two hollow mounting blocks 114 on the two opening fixing blocks 113 respectively, thereby completing the installation of the opening fixing block 113. When disassembling, press the two locking blocks 322 so that the two locking blocks 322 retract into the two sliding grooves 323 respectively, and then pull out the sliding rod 211 to remove the opening fixing block 113 for inspection and maintenance.
