The telescopic structure 5 is convenient for adjusting the length, and thus convenient for dragging the base 1 and the pedal structure 3.

[0032] As a technical optimization solution of the present utility model, a locking structure 6 is provided on the base 1. The locking structure 6 includes an installation block 601. The installation block 601 is fixedly connected to the base 1. A connecting sleeve 602 is fixedly connected to the installation block 601. A plug rod 603 with a cross-section of "dry" shape is slidably connected to the connecting sleeve 602. A fixing plate 605 is fixedly connected to the support frame 208.

The lifting structure 2 is locked through the locking structure 6, avoiding the shaking of the lifting structure 2 when moving the base 1 and the lifting structure 2, and improving the stability during movement.

[0033] When using this invention, to move the base 1 and the pedal structure 3, first rotate the boardwalk pedal 302 and the cabin pedal 303, then pull the lever 306. The lever 306 causes the anti-detachment block 307 to slide inside the fixing sleeve 305, compressing the first spring 308. After the boardwalk pedal 302 and the cabin pedal 303 are completely folded, the lever 306 can be released. The first spring 308 returns to its original position, causing the lever 306 to engage with the through holes 304 on the boardwalk pedal 302 and the cabin pedal 303, thus fixing the folded cabin pedal 303 and the boardwalk pedal 302. Then, lift the limit rod 508. The limit rod 508 rises and no longer engages with the limit hole 506 on the fixing strip 504. At this point, it is possible to... When the handle 503 is pulled out, it moves the fixing bar 504 and the slide bar 505 together. The slide bar 505 has an L-shaped cross-section, and its end hooks onto the base 1. Then, the limiting rod 508 is released, and the second spring 509 returns to its original position, causing the limiting rod 508 to engage with the limiting hole 506 on the slide bar 505, thus fixing the handle 503. At this time, the base 1 can be pulled by the handle 503. The other end of the base 1 is equipped with two moving wheels 7. The telescopic structure 5 and the moving wheels 7 facilitate the dragging and transfer of the base 1. When not in use, the wheels can be retracted, improving space utilization. When the base 1 is moved to the cabin door, the insertion rod 603 can be pulled, the third spring 604 is compressed, and the insertion rod 603 is no longer engaged with the base 1. The insertion hole 606 on the fixing plate 605 is inserted. At this time, the handwheel 214 can be rotated. The rotation of the handwheel 214 drives the screw 213 to rotate. The rotation of the screw 213 drives the mounting shaft 209 to move in the direction of the drive shaft 207. The roller 210 rolls inside the mounting groove 211. The inner bracket 202 and the outer bracket 204 rotate around the rotating shaft 203. The longitudinal angle between the inner bracket 202 and the outer bracket 204 decreases, and the height of the support frame 208 increases, thereby adjusting the height of the platform step 301. After the platform step 301 is adjusted to a suitable height, the boarding bridge step 302 and the cabin step 303 can be unfolded, so that the boarding bridge step 302 is placed on the boarding bridge and the cabin step 303 is unfolded. Placed inside the cabin, it facilitates the smooth entry and exit of passengers, wheelchairs of disabled persons, and large luggage. When it is necessary to disassemble the pedal structure 3, the lever 410 can be moved, which will cause the connecting frame 405 and the fixing block 407 to slide. The tension spring 409 extends, and the connecting frame 405 causes the locking block 404 to no longer engage with the slot 406 on the insert 402. At this time, the insert 402 at the bottom of the platform pedal 301 can be pulled out from the slot 401. Then, the cabin pedal 303 and the boarding bridge pedal 302 can be folded for easy storage. The pedal structure 3 can be quickly installed and disassembled through the installation structure 4. The setting of the guide shaft 408 improves the stability of the sliding of the fixing block 407 and prevents the tension spring 409 from deviating.
