DETAILED DESCRIPTION
[0021] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail in combination with the drawings and examples.
[0022] In one embodiment, as shown in Figures 1-4 A special transfer trolley for a side rear door of a container, comprising a frame 1, a bottom plate 2, universal wheels 3, a limiting assembly 5, the bottom plate 2 is provided with four universal wheels 3 opposite to each other on the lower surface, the universal wheels 3 are provided with universal wheel locks, the upper surface of the bottom plate 2 is fixedly connected with the frame 1 and the reclining frame 7;
[0023] The limiting assembly 5 is arranged at the side wall of the frame 1 and is used for limiting the side door frame of the container.
[0024] The frame part of the side door frame and the rear door frame is surrounded by the limiting assembly 5, so that when the staff pushes or pulls the trolley, the side door frame and the rear door frame can be prevented from falling off the ground and being damaged.
[0025] In one embodiment, as shown in Figure 1 The upper surface of the bottom plate 2 is fixedly connected with two symmetrical shelves 6.
[0026] The side door frame and the rear door frame are prevented from slipping off.
[0027] In one embodiment, as shown in Figure 3 and Figure 4 The limiting assembly 5 comprises a mounting plate 8 and a second rotary limiting plate 10, eight mounting plates 8 opposite to each other are fixedly connected with the side wall of the frame 1, the first rotary limiting plate 9 and the second rotary limiting plate 10 are rotatably connected with the side wall of the mounting plate 8 through a pin shaft, the first rotary limiting plate 9 and the second rotary limiting plate 10 are both L-shaped, the clamping block groove 16 is formed in the side wall of the first rotary limiting plate 9, the clamping block 12 is slidably connected with the inner side wall of the clamping block groove 16, the clamping groove 17 is formed in the side wall of the second rotary limiting plate 10, a plurality of springs are fixedly connected between the clamping block 12 and the inner side wall of the clamping block groove 16, the clamping block 12 is clamped with the clamping groove 17, the inclined block groove 15 is formed in the inner side wall of the clamping block groove 16, the first inclined block 13 is slidably connected with the inner side wall of the inclined block groove 15, the pressing rod 11 is slidably connected with the upper surface of the first rotary limiting plate 9 and extends into the inclined block groove 15, the second inclined block 14 is fixedly connected with the lower surface of the pressing rod 11 and abuts against the first inclined block 13, and the first inclined block 13 is fixedly connected with the clamping block 12.
[0028] Rotate the first rotation limit plate 9 and the second rotation limit plate 10 to surround the frame parts of the side door frame and the rear door frame. At the same time, press the pressing rod 11. The pressing rod 11 drives the second inclined block 14 to descend. The descent of the second inclined block 14 drives the first inclined block 13 to move into the inclined block groove 15. The first inclined block 13 drives the locking block 12 to move into the locking block groove 16. When the locking block 12 is aligned with the locking groove 17, release the hand that pressed the pressing rod 11. At this time, the locking block 12 returns to its original position under the action of the spring and completes the locking with the locking groove 17.

[0038] S3: Press the pressing rod 11 at the same time. The pressing rod 11 drives the second inclined block 14 to descend. The descent of the second inclined block 14 drives the first inclined block 13 to move into the inclined block groove 15. The first inclined block 13 drives the locking block 12 to move into the locking block groove 16. When the locking block 12 is in the same position as the locking groove 17, release the hand that pressed the pressing rod 11. At this time, the locking block 12 is reset under the action of the spring and completes the locking with the locking groove 17.
[0039] By using limiting components 5 to enclose the frame parts of the side door frame and the rear door frame, it is possible to prevent the side door frame and the rear door frame from tipping over and falling to the ground and causing damage when the staff pushes or pulls the trolley.
[0040] The limit and release operations for the side and rear door frames are quick and convenient, simple to operate, reduce the workload of employees, and help improve handling efficiency.
