Description

Technical Field

[0001] This utility model relates to the field of aircraft maintenance technology, and in particular to the hand-cranked gear fixing disc for aircraft engines. Background Technology

[0002] In the modern aviation industry, the safety and reliability of aircraft engines are of paramount importance. Regular maintenance and inspection are essential to ensure the proper functioning of aircraft engines. However, during maintenance, it is necessary to keep the engine from rotating. The original engine cover is merely a single cap and lacks the function of locking the engine in place. This necessitates the use of other tools to secure the engine during actual maintenance, but existing tools often lack the appropriate shape. Furthermore, leaving the cover uncovered allows impurities to easily enter the engine, causing considerable inconvenience. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a hand-cranked gear fixing disc for aircraft engines, which can both serve as a cover to close the engine opening and flexibly lock the engine to prevent internal gears from rotating; the pin method allows for flexible locking and unlocking, is easy to operate, and has a good locking effect; the overall structure of the device is simple, the operation is stable, it is flexible in adaptation, and it is highly practical.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a hand-cranked gear fixing plate for an aircraft engine, including a fixing plate. The fixing plate is provided with a locking cover and multiple mating holes. The mating holes are provided with mounting screws that mate with them. The locking cover is provided with multiple mounting holes. The inner wall of the locking cover is provided with a mounting pad. The mounting pad is provided with multiple alignment holes corresponding to the mounting holes. The alignment holes and mounting holes are provided with connecting screws that mate with them. The mounting pad is provided with an adjusting shaft that mates with it. One end of the adjusting shaft is provided with a handle, and the other end of the adjusting shaft is provided with a locking head.

[0005] In a preferred embodiment, the handle head and the locking head have the same shape.

[0006] In a preferred embodiment, the locking head has a square head structure.

[0007] In a preferred embodiment, the insertion end of the locking head is provided with a chamfered arc surface.

[0008] In a preferred embodiment, the mounting screw is an internal hexagon screw.

[0009] In the preferred embodiment, the adjusting shaft is locked in place with the mounting pad pin.

[0010] The hand-cranked gear fixing disc for aircraft engines provided by this utility model, by adopting the above-described structure, has the following beneficial effects:

[0011] (1) It can both seal the engine opening as a cover and lock the engine in a flexible manner to prevent the internal gears from rotating;

[0012] (2) The latch mechanism allows for flexible locking and unlocking, is easy to operate, and provides a good locking effect;

[0013] (3) The device has a simple overall structure, stable operation, flexible adaptation and strong practicality. Attached Figure Description

[0018] like Figure 1-2 The aircraft engine hand-cranked gear fixing plate includes a fixing plate 1. The fixing plate 1 is provided with a locking cover 2 and multiple mating holes 3. The mating holes 3 are provided with mounting screws 4 that mate with them. The locking cover 2 is provided with multiple mounting holes 7. The inner wall of the locking cover 2 is provided with a mounting pad 5. The mounting pad 5 is provided with multiple alignment holes 6 that correspond to the mounting holes 7. The alignment holes 6 and the mounting holes 7 are provided with connecting screws 8 that mate with them. The mounting pad 5 is provided with an adjusting shaft 9 that mates with it. One end of the adjusting shaft 9 is provided with a handle head 10, and the other end of the adjusting shaft 9 is provided with a locking head 11.

[0019] In a preferred embodiment, the handle 10 and the locking head 11 have the same shape. This facilitates operation and allows for control over the state of the internal locking head 11.

[0020] In the preferred embodiment, the locking head 11 has a square head structure, ensuring precise and stable positioning during assembly.

[0021] In a preferred embodiment, the insertion end of the locking head 11 is provided with a chamfered arc surface to facilitate insertion and matching with the groove inside the engine.

[0022] In the preferred embodiment, the mounting screw 4 is an internal hex socket screw. This facilitates disassembly and assembly and is highly practical.

[0023] In a preferred embodiment, the adjusting shaft 9 and the mounting pad 5 are locked together by a pin. The adjusting shaft 9 and the mounting pad 5 are unlocked and locked by mutual insertion and removal, ensuring that the engine is securely locked and not easily loosened.

[0024] The method of using this utility model is as follows: Install the fixing plate 1 on the original engine cover and fix it by the mounting screw 4. Then, operate the handle head 10 to drive the locking head 11 to align with the inner square groove inside the engine. After alignment, push the handle head 10 in. The adjusting shaft 9 and the mounting pad 5 are locked by the pin to prevent the internal gears of the engine from rotating and to locate and inspect.

[0025] The advantages of this utility model are: it can both seal the engine opening and flexibly lock the engine to prevent internal gears from rotating; the pin method allows for flexible locking and unlocking, making it easy to operate and providing a good locking effect; the overall structure of the device is simple, the operation is stable, it is flexible in its adaptation, and it is highly practical.
