[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 and Figure 3 This utility model provides an embodiment of an automatic loading structure for a van, comprising a support column 1 and a base 2. A motor 14 is fixed to the inner wall of the base 2, and a drive shaft 15 is fixedly connected to the output end of the motor 14. A first pulley 20 is fixedly connected to the outer wall of the drive shaft 15, and a slider 12 is slidably connected to the outer wall of the drive shaft 15. A third connecting shaft 11 is rotatably connected to the inner wall of a plurality of sliders 12, and a connecting block 10 is rotatably connected to the outer wall of a plurality of third connecting shafts 11. A platform 8 is fixedly connected to the outer wall of a plurality of connecting blocks 10, and a second connecting shaft 9 is rotatably connected to the inner wall of the platform 8. A connecting rod 7 is rotatably connected to the outer wall of the second connecting shaft 9. A first connecting shaft 6 is rotatably connected to the inner wall of the base 2, and a second rotating shaft 19 is rotatably connected to the inner wall of the base 2. A second pulley 21 is fixedly connected to the outer wall of the second rotating shaft 19. A belt is sleeved on the outer wall of the first pulley 20 and the second pulley 21. A lifting assembly is provided on the inner wall of the base 2.

[0024] Specifically, the starter motor 14 drives the drive shaft 15, which in turn drives the first pulley 20 to rotate. The outer walls of the first pulley 20 and the second pulley 21 are fitted with belts, which in turn drive the second pulley 21 to rotate together. The second pulley 21 then drives the second rotating shaft 19. In this way, one slider 12 slides on the outer wall of the drive shaft 15, and the other slider 12 slides on the outer wall of the second rotating shaft 19. Through the cooperation between the connecting block 10, the third connecting shaft 11, the second connecting shaft 9, the connecting rod 7, and the first connecting shaft 6, the platform 8 is rotated at an angle, and the goods on the platform 8 are poured into the carriage, thus realizing the tilting function.

[0025] Reference Figure 3The lifting assembly includes a first rotating shaft 16, a rotating rod 5 fixedly connected to one end of the first rotating shaft 16, a second bevel gear 18 fixedly connected to the outer wall of the first rotating shaft 16, a first bevel gear 17 meshing with the tooth ends of a plurality of second bevel gears 18, and a threaded rod 23 threadedly connected to the inner wall of a plurality of first bevel gears 17.

[0026] Specifically, the twisting rod 5 drives the first rotating shaft 16, which in turn drives multiple second bevel gears 18. Since the teeth of the multiple second bevel gears 18 are meshed with the first bevel gears 17, they will drive the multiple first bevel gears 17 to rotate together. The multiple threaded rods 23 will rotate on the inner wall of the first bevel gears 17. The direction of the rotating rod 5 can be controlled to raise and lower the platform 8, which is convenient to adapt to carriages of different heights.

[0027] Reference Figure 3 and Figure 4 The outer walls of multiple threaded rods 23 are rotatably connected to limit cylinders 22, and the outer walls of multiple limit cylinders 22 are fixedly connected to the inner wall of the support column 1.

[0028] Specifically, when the rotating rod 5 is twisted, the multiple threaded rods 23 rotate on the inner wall of the first bevel gear 17 and also rotate on the inner wall of the multiple limiting cylinders 22, thereby limiting the threaded rods 23 through the limiting cylinders 22.

[0029] Reference Figure 2 and Figure 4 The bottom four corners of the tabletop 8 are all fixedly connected with telescopic rods 4, and the bottoms of the multiple telescopic rods 4 are fixedly connected to the top of the support column 1.

[0030] Specifically, when the rotating rod 5 is twisted, multiple threaded rods 23 rotate simultaneously on the inner wall of the first bevel gear 17 and the limiting cylinder 22, driving multiple telescopic rods 4 to rise and fall together through the platform 8.

[0031] Reference Figure 1 and Figure 2 The inner walls of multiple connecting rods 7 are rotatably connected to the outer wall of the first connecting shaft 6.

[0032] Specifically, the first connecting shaft 6 fixes one end of multiple connecting rods 7, and together with multiple connecting blocks 10 and multiple third connecting shafts 11, the tabletop 8 is flipped.

[0033] Reference Figure 1 and Figure 2 The inner wall of one of the sliders 12 is slidably connected to the outer wall of the second rotating shaft 19. The top of the base 2 is provided with multiple grooves, and the outer walls of multiple sliders 12 are slidably connected to the inner wall of the base 2 through the grooves.

[0034] Specifically, the starter motor 14 drives the second rotating shaft 19 through the second pulley 21, causing one slider 12 to slide on the outer wall of the second rotating shaft 19, while another slider 12 slides on the outer wall of the drive shaft 15. In this way, multiple sliders 12 slide on the inner wall of the base 2 through the slide groove.

[0035] Reference Figure 4 Hinges 13 are fixedly connected to both sides of the inner wall of multiple support columns 1, columns are fixedly connected to the adjacent side of multiple support columns 1, and hinges 13 are fixedly connected to both ends of multiple columns.

[0036] Specifically, multiple hinges 13 are used to fix and connect multiple columns and multiple support columns 1, which serve to provide support and fixation.

[0037] Reference Figure 4 Multiple columns have multiple casters fixedly connected to both ends.

[0038] Specifically, by installing multiple casters 3 under multiple columns, the equipment can be moved, making it convenient and flexible to move and use.

[0039] Working principle: The present invention starts the motor 14 to drive the transmission shaft 15, the transmission shaft 15 drives the first pulley 20, the outer wall of the first pulley 20 and the second pulley 21 is fitted with a belt, thereby driving the second rotating shaft 19 to rotate. At this time, multiple sliders 12 slide on the outer wall of the transmission shaft 15 and the second rotating shaft 19. The multiple sliders 12 can be rotatably connected to the platform 8 through multiple third connecting shafts 11 and multiple connecting blocks 10. At the same time, the inner wall of the platform 8 is rotatably connected to the second connecting shaft 9. The multiple second connecting shafts 9 are rotatably connected to multiple connecting rods 7. The multiple connecting rods 7 are rotatably connected to the first connecting shaft 6. The first connecting shaft 6 is rotatably connected to the inner wall of the base 2. When the sliders 12 slide on the inner wall of the base 2, they will cause the platform 8 to flip, so that the goods on the platform 8 can be poured into the carriage.

[0040] This utility model first delivers the goods to the platform 8, then moves the equipment to the loading point using multiple casters 3 and locks the casters 3 to prevent the equipment from moving. Next, the rotating rod 5 is turned to drive the first rotating shaft 16, which in turn drives multiple second bevel gears 18. The teeth of the multiple second bevel gears 18 mesh with the first bevel gear 17, so that the second bevel gears 18 can rotate with the first bevel gear 17, thereby driving multiple threaded rods 23 to rotate within the limiting cylinder 22, thereby driving multiple telescopic rods 4 to move together to achieve a lifting effect. The height of the platform 8 can be adjusted by turning the rotating rod 5 to adapt to carriages of different heights.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
