Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. However, those skilled in the art will understand that the embodiments described below are only some embodiments of this utility model, not all embodiments, and are only used to illustrate this utility model, and should not be regarded as limiting the scope of this utility model. 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. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall apply.

[0023] See Figures 1 to 7The present invention provides an adjustable conveying device, comprising, from bottom to top, a movable lifting group 1, a first extension group 2, and a second extension group 3. The first extension group 2 includes a connecting plate 21 and a grid plate 23. The movable lifting group 1 includes a base plate 12 and a lifting assembly 11. The lifting assembly 11 is located on the upper end of the base plate 12. A caster wheel 13 is connected to the lower end of the base plate 12. A connecting column 32 and a support column 311 are provided on the upper end of the grid plate 23. The upper end of the connecting column 32 is connected to the second extension group 3. A telescopic assembly 31 is provided between the first extension group 2 and the second extension group 3. The telescopic assembly 31 is located on the support column 311. The second extension group 3 includes a main telescopic box 33. A secondary telescopic box 34 and a secondary telescopic box 35 are hinged to both sides of the main telescopic box 33.

[0024] See Figure 3 The lifting assembly 11 includes two sets of hinged lifting rods 111. The bottom end of each lifting rod 111 is connected to the piston shaft of an electric cylinder 112. The bottom end of each lifting rod 111 is slidably connected to the base plate 12. A sliding connecting block 114 is hinged to the top end of each lifting rod 111. A synchronizing rod 113 connects the bottom ends of the two sets of lifting rods 111, and the connection position is consistent with the height of the piston shaft of the electric cylinder 112. The synchronizing rod 113 is perpendicular to the lifting rod 111. The extension and retraction of the electric cylinder 112 drives the lifting rod 111 to rotate along the hinge shaft, thereby achieving height adjustment of the first extension group 2 and the second extension group 3.

[0025] See Figure 4 The grid plate 23 is connected to the upper end of the connecting plate 21. The grid plate 23 includes two sets of mutually perpendicular extension rods. Each set of extension rods includes several parallel outer rods 231 and inner rods 232 slidably connected to the inner side of the outer rods 231. Each outer rod 231 has two inner rods 232 connected inside, and the two inner rods 232 are located at the two ends of the outer rod 231 respectively. A stabilizing rod is fixedly connected between the parallel inner rods 232 at the same end. The length of the extension rod can be changed by sliding the inner rods 232 relative to the outer rods 231, thereby changing the overall size of the grid plate 23.

[0026] See Figure 6 and Figure 7The main telescopic box 33 includes, from the outside to the inside, an outer box 331, a second box 333, a third box 336, and an inner box 3310. There is no connection between the outer box 331, the second box 333, the third box 336, and the inner box 3310. The inner wall of the outer box 331 is provided with a rack 332. The side wall of the second box 333 is provided with a sliding groove, and a linkage gear 334 is slidably connected in the sliding groove. The linkage gear 334 meshes with the rack 332. The outer wall of the third box 336 is provided with a rack 337, and the linkage gear 334 meshes with the rack 337. The inner wall of the second box 333 is provided with a rack 335. The side wall of the third box 336 is provided with a sliding groove, and a linkage gear 338 is slidably connected in the sliding groove. The linkage gear 338 meshes with the rack 335. The outer wall of the inner box 3310 is provided with a rack 339, and the linkage gear 338 meshes with the rack 339. An electric push rod 3311 is provided inside the main telescopic box 33, and the push rod of the electric push rod 3311 is connected to the second box 333. The electric push rod 3311 pushes the second box 333 outward, causing displacement of the second box 333 relative to the outer box 331. The action of rack 1 332 causes the linkage gear 1 334 to rotate. The rotation of linkage gear 1 334 acts on rack 3 337, pushing rack 3 337 outward. Rack 3 337 drives the third box 336 outward, causing displacement of the third box 336 relative to the second box 333. This displacement causes linkage gear 2 338 to rotate, which in turn acts on rack 4 339, pushing rack 4 339 outward. Rack 4 339 then drives the inner box 3310 outward, causing displacement of the inner box 3310 relative to the third box 336. This layered gear and rack structure works in tandem, causing the secondary telescopic boxes 331 to be pushed out sequentially, expanding the area and enlarging the storage platform of the main telescopic box 33.

[0027] In production, the box structure inside the main telescopic box 33 is not limited to the four boxes in this embodiment. More structures can be added based on the same structure and principle, which will not be elaborated here.

[0028] The outer box 331, the second box 333, the third box 336, and the inner box 3310 have two sets of opposite directions in the main telescopic box 33. The auxiliary telescopic boxes 34 and 35 have the same internal structure as the main telescopic box 33. By combining the identical internal structure of the main telescopic box 33, the auxiliary telescopic boxes 34 and 35, the second extension group 3 can be expanded to a larger area, effectively adjusting the storage area of ​​the conveying device.

[0029] See Figure 5The telescopic assembly 31 includes an electric cylinder 312, wherein the cylinder barrel of the electric cylinder 312 is hinged to the support column 311, and the piston shaft of the electric cylinder 312 is hinged to the bottom ends of the auxiliary telescopic box 34 and the auxiliary telescopic box 35. The telescopic movement of the electric cylinder 312 can control the lifting angle of the bottom ends of the auxiliary telescopic box 34 and the auxiliary telescopic box 35, thereby enabling the rotation of the auxiliary telescopic box 34 and the auxiliary telescopic box 35 along the hinge point with the main telescopic box 33, thus controlling the lifting and lowering of the auxiliary telescopic box 34 and the auxiliary telescopic box 35, and controlling the usable area of ​​the second extension group 3. In use, heavier items are placed in the main telescopic box 33 or the part supported by the electric cylinder 312, while lighter items are placed in other parts. This allows for the transport of a sufficient number of items while maintaining the stability of the handling device. Specifically, the electric cylinder 312 has a self-locking function, which can remain locked after operation stops, enhancing safety and convenience.

[0030] The connection between the movable lifting group 1, the first extension group 2, and the second extension group 3 is as follows: the bottom end of the connecting plate 21 is provided with a sliding connecting groove 22, and the sliding connecting block 114 is slidably connected to the sliding connecting groove 22. (See attached image) Figure 3 The upper end of the grid plate 23 is provided with a connecting post 31, and the upper end of the connecting post 31 is connected to the bottom of the control box 32.

[0031] The beneficial effects of this utility model are: through the interaction between the movable lifting group, the first extension group and the second extension group, both the height and the storage area can be effectively controlled, enabling the loading and unloading of equipment and materials of different shapes and sizes.

[0032] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
