[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1:

[0026] Reference Figure 1-5 A multi-functional chair carrier includes a frame 1, a lower guide rail 2 mounted on the frame 1, a fixed frame 3 slidably connected to the lower guide rail 2, a lifting mechanism on the fixed frame 3, a sliding seat 4 fixedly connected to the lifting end of the lifting mechanism, a rotating mechanism mounted on the sliding seat 4, a rotating base 6 fixedly connected to the rotating end of the rotating mechanism, and a tray 602 for fixing the chair basin slidably mounted on the rotating base 6.

[0027] A guide cylinder 703 is fixedly connected to the fixed frame 3. A pin 7 is slidably connected inside the guide cylinder 703. A pin hole 705 is provided on the lower guide rail 2, and the pin 7 is inserted into the pin hole 705.

[0028] A limiting shaft 701 is fixedly connected to the pin 7. The guide cylinder 703 is provided with two layers of limiting grooves 704, which are arranged vertically. When the limiting shaft 701 is located in the upper limiting groove 704, the pin 7 is not inserted into the pin hole 705, which facilitates the sliding of the fixing frame 3 on the lower guide rail 2. When the limiting shaft 701 is located in the lower limiting groove 704, the pin 7 can be inserted into the pin hole 705 to limit the movement of the fixing frame 3. Specifically, the sliding distance of the fixing frame 3 on the lower guide rail 2 is 0-800mm.

[0029] A gripping rod 702 is fixedly connected to the pin 7, which facilitates the pulling of the pin 7.

[0030] The lifting mechanism includes a rotating lead screw 401 rotatably connected in the sliding seat 4, and a lead screw seat 302 threadedly connected to the rotating lead screw 401, which is fixedly connected to the fixed frame 3.

[0031] A guide block 301 is installed on the fixed frame 3, and a column 402 is fixedly connected to the sliding seat 4. The column 402 is slidably connected to the guide block 301. By setting the rotating screw 401 and the threaded screw seat 302, and cooperating with the guide of the column 402, the height of the sliding seat 4 on the fixed frame 3 can be adjusted. Specifically, the height adjustment range is 0-170mm.

[0032] The lifting mechanism can also use a jack, with the fixed end of the jack connected to the fixed frame 3 and the telescopic end installed at the lower end of the sliding seat 4.

[0033] The rotating mechanism includes a rotating base 5, which is rotatably connected to a sliding seat 4. Both the sliding seat 4 and the rotating base 5 are provided with insertion holes 501, and insertion shafts are inserted into the insertion holes 501. The chair basin can be tilted forward by the insertion holes 501 and the insertion shafts, with a tilting angle of 68°.

[0034] A rotating shaft 502 is fixedly connected to the rotating base 5, and a rotating base 6 is rotatably connected to the rotating shaft 502, allowing the chair basin to rotate 360° on the rotating base 5. (Refer to...) Figure 4 Multiple sets of protrusions are provided on the side wall of the rotating base 6, and a gap is provided between two adjacent protrusions. A protrusion slides on the rotating base 5. When the protrusion is inserted into the gap, the rotation direction of the rotating base 6 is locked. Specifically, the rotation stopping angle of the rotating base 6 is 45°, 90°, 135°, and 180°.

[0035] An upper guide rail 601 is fixedly connected to the rotating base 6, and a support plate 602 is slidably connected to the upper guide rail 601.

[0036] The lower end of the frame 1 is equipped with a movable wheel 101, and a traction frame 102 is installed on the frame 1. The traction frame 102 and the movable wheel 101 facilitate the movement of the frame 1.

[0037] When the seat needs to be inspected, loosen the fixing nuts on the seat, remove the nuts, and then bring the multi-functional seat trolley close to the seat storage shelf. Using the lifting mechanism and the sliding fixing frame 3, place the tray 602 at the lower end of the seat basin, connect and fix it to the seat basin, and raise the rotating base 6 and the tray 602 through the lifting mechanism to separate the seat basin from the seat frame after the nuts are removed.

[0038] At this point, the placement angle of the chair basin can be adjusted using the lifting and rotating mechanisms.

[0039] This utility model not only enables the transportation and storage of the entire seat during scheduled inspections, but also facilitates the disassembly, fixing, transportation, and storage of the seat component, the seat basin. It allows the seat basin to be raised and lowered by 0-170mm and moved forward and backward by 0-800mm. It can meet the scheduled inspection requirements of 360° rotation, 45°, 90°, 135°, and 180° position fixation along the rotation axis 502, and 68° forward tilt of the seat basin mounting base.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
