[0024] Specifically, start the stacker body 2 and move it to the stacking location. Since the nut 11 is fixedly connected to the threaded rod 7, rotating the nut 11 causes the threaded rod 7 to rotate synchronously. Since the turntable 6 is fixedly connected to the threaded rod 7, the turntable 6 rotates driven by the threaded rod 7, and then the limit column 9 slides with the rotation of the turntable 6. Since the limit column 9 is fixedly connected to the slider 8, the slider 8 slides driven by the limit column 9, and then the slider 8 is separated from the anti-falling plate 3, and then the anti-falling plate 3 is moved to rotate around the rotating shaft 4, and finally the anti-falling plate 3 and the base 1 form an oblique angle, and the anti-falling plate 3 supports the stacker body 2, thereby preventing the stacker body 2 from tipping over due to changes in the center of gravity during the stacking process.

[0025] Reference Figure 1 and Figure 5 The fixed assembly includes a limit block 13, the outer wall of the limit block 13 is fixedly connected to the outer wall of the stacker body 2, and the inner top wall of the limit block 13 is fixedly connected with a fixed block 14;

[0026] Specifically, the stacker body 2 fixes the limiting block 13 on the surface of the stacker body 2 , and the limiting block 13 fixes the fixing block 14 inside the limiting block 13 .

[0027] Reference Figure 1 、 Figure 4 and Figure 5 , the inner wall of the anti-reverse plate 3 is rotatably connected to the outer wall of the rotating shaft 4, the outer wall of the limiting column 9 is arranged on the inner wall of the turntable 6, the outer wall of the limiting column 9 is arranged inside the first groove 10, and the slider 8 is arranged inside the anti-reverse plate 3; the outer wall of the threaded rod 7 is fixedly connected with a nut 11; the inner wall of the fixed block 14 is fixedly connected to the electric push rod 15, the output end of the electric push rod 15 is connected to the pull rod 16, the outer wall of the pull rod 16 is rotatably connected to the first transmission rod 17, the inner wall of the first transmission rod 17 is fixedly connected to the second transmission rod 18, the inner wall of the second transmission rod 18 is fixedly connected to the third transmission rod 20, the inner wall of the limiting block 13 is fixedly connected to the fixing column 19, and the outer wall of the third transmission rod 20 is provided with a camera 21; the inner wall of the third transmission rod 20 is rotatably connected to the outer wall of the fixing column 19;

[0028] Specifically, the electric push rod 15 is turned on to drive the pull rod 16 to move up and down. When the pull rod 16 moves up and down, it will drive the first transmission rod 17 to rotate. Since the first transmission rod 17 is fixedly connected to the second transmission rod 18, the first transmission rod 17 will drive the second transmission rod 18 to rotate. Since the second transmission rod 18 is fixedly connected to the third transmission rod 20, the second transmission rod 18 will drive the third transmission rod 20 to rotate. When the cargo blocks the user's field of vision when the stacker body 2 is stacked, the camera 21 can detect the road conditions in front of the stacker body 2, and finally achieve the effect of quickly installing and disassembling the camera 21, thereby avoiding collisions while facilitating the replacement of camera 21 parts.

[0029] Working principle: when the anti-dumping structure needs to be used, first start the stacker body 2 to the designated location, then turn the nut 11 to drive the threaded rod 7 to rotate inside the slide rail 5, and at the same time, the turntable 6 rotates synchronously with the rotation of the threaded rod 7, and then the limiting post 9 slides inside the first groove 10 driven by the turntable 6, and then the slider 8 slides along the inner wall of the slide rail 5 driven by the limiting post 9. At this time, the slider 8 is pulled out from the inside of the anti-dumping plate 3, and then the anti-dumping plate 3 rotates around the rotating shaft 4 under the action of its own weight, and at the same time, the turntable 6 passes through the second groove 12 to make the anti-dumping plate 3 fall smoothly, and finally the anti-dumping plate 3 and the base 1 form an oblique angle, and the anti-dumping plate 3 supports the stacker body 2, thereby preventing the stacker body 2 from tipping over due to the change of the center of gravity during the stacking process; start the electric push rod 15 to The movable pull rod 16 moves up and down. When the pull rod 16 moves up and down driven by the electric push rod 15, the pull rod 16 will drive the first transmission rod 17 to rotate, and then the first transmission rod 17 will drive the second transmission rod 18 to rotate synchronously, and then the second transmission rod 18 will drive the third transmission rod 20 to rotate around the fixed column 19. When the cargo blocks the user's field of vision when the stacker body 2 is stacked, the camera 21 can detect the road conditions in front of the stacker body 2, and finally achieve the effect of quickly installing and removing the camera 21, thereby avoiding collisions while facilitating the replacement of camera 21 parts; the anti-dumping structure of the pedestrian electric stacker can not only prevent the stacker body 2 from tipping over due to changes in the center of gravity during the stacking process, but also avoid collisions while facilitating the replacement of camera 21 parts.
