Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Example 1:

[0029] This embodiment provides a lift for aviation ground tooling, specifically as follows: Figure 3 , Figure 4 As shown, it includes:

[0030] The housing has an input end and an output end. The input end includes an adjusting rod 104, and the output end includes a connecting plate 207.

[0031] The conversion unit can amplify the rotational torque input at the rocker 204 and convert it into a linear torque that is transmitted unidirectionally to the connecting plate 207.

[0032] The reversing section transmits the power at the adjusting rod 104 to the conversion section;

[0033] The conversion unit converts rotational power into linear power through threaded engagement; the reversing unit transmits power in a different direction through gear engagement.

[0034] By incorporating a conversion section with torque amplification capabilities, operators can easily adjust the length of the lifting device. Furthermore, the self-locking property of the thread enhances stability after adjustment. The reversing section changes the input position of the torque, allowing operators to quickly adjust the device even when working in confined spaces, thus increasing its adaptability.

[0035] Example 2:

[0036] This embodiment further extends the above embodiment, specifically as follows: Figures 4-5 As shown, the housing includes an input chamber and a conversion chamber, the conversion chamber including a conversion chamber body 202; the conversion part includes a lead screw 212 rotatably connected to the conversion chamber body 202 and a conversion shaft slidably connected to the conversion chamber body 202, the conversion shaft being threadedly connected to the lead screw 212, the conversion shaft being drivenly connected to the connecting plate 207, and the lead screw 212 being drivenly connected to the reversing part.

[0037] Furthermore, the conversion shaft includes a telescopic cylinder 215 and a threaded sleeve 214. The threaded sleeve 214 is fixedly connected to the telescopic cylinder 215 by screws, and the threaded sleeve 214 is threadedly connected to the lead screw 212.

[0038] Furthermore, a rubber pad 213 is installed on the threaded sleeve 214 using screws, a limit ring 216 is installed at the end of the lead screw 212, an auxiliary cylinder 208 is installed on the connecting plate 207, and a connecting pin 209 is inserted between the auxiliary cylinder 208 and the telescopic cylinder 215.

[0039] When the lead screw 212 rotates, due to the threaded connection between the lead screw 212 and the threaded sleeve 214, and the inability of the telescopic cylinder 215 to rotate, the threaded sleeve 214, carrying the telescopic cylinder 215, begins to slide on the conversion chamber 202 to achieve telescopic adjustment. The detachable threaded sleeve 214 is provided so that it can be easily replaced when worn, without having to replace the entire conversion shaft, and the telescopic cylinder 215 can continue to be used. The rubber pad 213 is set to reduce the impact force between the threaded sleeve 214 and the end of the conversion chamber 202, and to play a buffering role; the limiting ring 216 is set to limit the displacement of the threaded sleeve 214; when the connecting plate 207 extends, the threaded sleeve 214 contacts the upper surface of the limiting ring 216, at which time the limiting ring 216 will restrict the threaded sleeve 214 from continuing to move, preventing the threaded sleeve 214 from disengaging from the lead screw 212; when the connecting plate 207 retracts, the auxiliary cylinder 208 will contact the lower surface of the limiting ring 216 to prevent the threaded sleeve 214 from interfering with the end of the conversion chamber 202.

[0040] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0041] Example 3:

[0042] This embodiment further extends the above embodiment, specifically as follows: Figures 3-5 As shown, the conversion chamber includes an input chamber body 201 and a chamber cover 203. The chamber cover 203 is detachably mounted on the input chamber body 201 by screws. The rocker arm 204 is rotatably connected to the input chamber body 201. The reversing part includes a first bevel gear 210 and a second bevel gear 211. The first bevel gear 210 is mounted on the rocker arm 204, and the second bevel gear 211 is mounted on the lead screw 212. The first bevel gear 210 and the second bevel gear 211 mesh. The above mounting points are connected using methods including but not limited to bearings, pins, keys, and snap rings. This connection method is a conventional selection method made by those skilled in the art based on actual conditions, and will not be described in detail here.

[0043] When the operator cranks the lever 204, the first bevel gear 210 rotates synchronously. At this time, the first bevel gear 210 drives the second bevel gear 211, which in turn drives the lead screw 212 to rotate, thereby driving the conversion unit. The detachable cover 203 is provided to facilitate the installation and maintenance of the reversing unit.

[0044] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0045] Example 4:

The upper clamping plate 205 is fixedly connected to the housing, and the upper clamping plate 205 is provided with a plurality of through holes for bolts to pass through.

[0047] Furthermore, the mounting base also includes a lower clamping plate 206, which is attached to the outer wall of the housing, and the lower clamping plate 206 is provided with bolt holes corresponding to the through holes on the upper clamping plate 205.

[0048] The upper clamping plate 205 can be fixed to the tooling with bolts to achieve installation; the lower clamping plate 206 is set so that multiple bolts form a whole, further strengthening the installation strength of the lifting device 2.

[0049] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0050] Example 5:

[0051] This embodiment provides a ground tooling for aviation, using the elevator disclosed in the above embodiments, specifically as follows: Figures 1-2 As shown, the device includes a ground fixture 1 and a lifting device 2. The ground fixture 1 includes a mounting frame 101, on which a limiting sleeve 103 and a fixture table 105 are mounted. An adjusting rod 104 is slidably connected to the limiting sleeve 103, which is used to strengthen the connection of the adjusting rod 104. A roller 102 is installed at the end of the adjusting rod 104. The mounting seat of the lifting device 2 is connected to the fixture table 105, and the output end of the lifting device 2 is connected to the adjusting rod 104.

[0052] By having the staff shake the rocker arm 204, the connecting plate 207 extends and retracts. When the connecting plate 207 extends, it drives the adjusting rod 104 to extend. At this time, the adjusting rod 104 drives the roller 102 to press on the ground, so that the mounting frame 101 is raised and lifted off the ground. At this time, the height of the tooling table 105 can be adjusted, and the entire ground tooling 1 can be moved easily.
