The rotation of the sixth sprocket 43 drives the rotation of the eighth rotating shaft 44, which in turn drives the rotation of the third bevel gear 45, which in turn drives the rotation of the fourth bevel gear 46, which in turn drives the rotation of the ninth rotating shaft 48, which in turn drives the rotation of the fifth bevel gear 49, which in turn drives the rotation of the sixth bevel gear 410, which in turn drives the rotation of the threaded rod 411, which in turn drives the rotation of the threaded rod 411, which in turn drives the movement of the moving plate 412, which in turn drives the movement of the third fixed plate 413, which in turn drives the movement of the roller 414. The roller 414 is moved out to facilitate workers to place large items on the roller 414 for movement, thereby reducing the labor intensity of workers and increasing the practicality of the device.
[0039] Specifically, when clamping the goods, the threaded rod 411 rotates three to four times, which moves the roller 414 down to the bottom of the second groove via the moving plate 412, causing the roller 414 to retract. If the threaded rod 411 continues to rotate, it will continue to move the roller 414 down via the moving plate 412.
[0040] The inner sides of the two clamping outer plates 316 are provided with a third groove. The first ends of two telescopic rods 318 are respectively installed in the third groove. The second ends of the two telescopic rods 318 are connected to the same clamping inner plate 317. A compression spring 319 is installed on the telescopic rods 318. The first end of the compression spring 319 is connected to the inner wall of the third groove. The second end of the compression spring 319 is connected to the clamping inner plate 317. The clamping inner plate 317 is slidably disposed in the third groove. A rubber layer 316 is installed on the inner side of the clamping inner plate 317. The rubber layer 316 is used for cushioning to prevent large items from being damaged.
[0041] Preferably, the telescopic rod 318 and the compression spring 319 work together to make the clamping inner plate 317 more stable in clamping and fixing large goods.
[0042] The method of using this invention: When it is necessary to move large items in logistics transportation, the worker moves the handling device to the location of use by using the movable wheels 1 and the push handle 101. Then, the worker rotates the drive component 21, which drives the tenth rotating shaft 221 to rotate. The rotation of the tenth rotating shaft 221 drives the worm gear 220 to rotate. The rotation of the worm gear 220 drives the worm wheel 219 to rotate. The rotation of the worm wheel 219 drives the first rotating shaft 22 to rotate. The rotation of the first rotating shaft 22 drives the first sprocket 24 to rotate. The rotation of the first sprocket 24 drives the second sprocket 215 to rotate. The rotation of the second sprocket 215 drives the second sprocket... The rotation of shaft 27 causes the third rotating rod 216 to rotate, which in turn causes the fifth rotating shaft 217 to rotate. Since the third gear 214 is fixed in place by the fixed post 26, the rotation of the fifth rotating shaft 217 causes the second gear 210 to revolve around and rotate on its own axis. The rotation of the second gear 210 causes the first gear 29 to rotate, which in turn causes the third rotating shaft 28 to rotate. The rotation of the third rotating shaft 28 causes the first rotating rod 212 to rotate, which in turn causes the fourth rotating shaft 211 to move and rotate. The movement of the fourth rotating shaft 211 then causes the fifth rotating shaft 217 to rotate. The movement of the first support housing 3 causes the second support housing 4 to move, thus moving the second support housing 4 to the top. This eliminates the need for workers to bend over excessively during placement and handling, reducing their workload and increasing efficiency. Simultaneously, the rotation of the fourth rotating shaft 211 drives the first bevel gear 31 to rotate, which in turn drives the second bevel gear 32. The second bevel gear 32 then drives the sixth rotating shaft 33, which in turn drives the third sprocket 34. The third sprocket 34 then drives the fourth sprocket 314. 4. The rotation drives the seventh rotating shaft 38 to rotate, which in turn drives the fourth gear 39 and the fifth gear 310 to rotate. The rotation of the fourth gear 39 and the fifth gear 310 drives the second arc-shaped rack plate 311 and the first arc-shaped rack plate 36 to rotate. The rotation of the second arc-shaped rack plate 311 and the first arc-shaped rack plate 36 drives the first connecting rod 37 and the second connecting rod 312 to rotate. The rotation of the first connecting rod 37 and the second connecting rod 312 drives the two moving rods 315 to move. The movement of the moving rods 315 drives the clamping outer plate 316 to move, thereby separating the two clamping outer plates 316.Simultaneously, the rotation of the seventh shaft 38 drives the fifth sprocket 41 to rotate, which in turn drives the sixth sprocket 43 to rotate. Specifically, the rotation of the fifth sprocket 41 half a turn drives the sixth sprocket 43 to rotate many times. The rotation of the sixth sprocket 43 drives the eighth shaft 44 to rotate, which in turn drives the third bevel gear 45 to rotate. The rotation of the third bevel gear 45 drives the fourth bevel gear 46 to rotate, which in turn drives the ninth shaft 48 to rotate. The rotation of the ninth shaft 48 drives the fifth bevel gear 49 to rotate, which in turn drives the sixth bevel gear... The sixth bevel gear 410 rotates, causing the threaded rod 411 to rotate. The rotation of the threaded rod 411 causes the moving plate 412 to move. The movement of the moving plate 412 causes the third fixed plate 413 to move. The movement of the third fixed plate 413 causes the roller 414 to move. The roller 414 moves out, making it easier for workers to place large items on the roller 414 for movement, thereby reducing the labor intensity of workers and increasing the practicality of the device. Then, the workers place the large items on the second support housing 4 and move them to a suitable position via the roller 414. Then, depending on the size of the goods, the operation is reversed. When the goods are large, as the second support housing 4 moves the goods into the vertical plate 2, the clamping inner plates 317 move towards each other, thus clamping and fixing the larger goods placed on the second support housing 4. At the same time, the threaded rod 411 rotates three to four times, which moves the moving plate 412 and drives the roller 414 down to below the second groove, causing the roller 414 to retract. When the goods are small, as the second support housing 4 moves the goods into the vertical plate 2 and is about to reach the bottom, the clamping inner plates 317 move towards each other, thus... Smaller items placed on the second support housing 4 are clamped and fixed. Simultaneously, the threaded rod 411 rotates three to four times, causing the moving plate 412 to move the roller 414 down to below the second groove. The roller 414 retracts, and the threaded rod 411 continues to rotate, causing the moving plate 412 to continue moving the roller 414 down. This allows for clamping of both large and small items. The vertical plate 2 protects the items during movement, preventing collisions and damage. Once the items are in their designated placement position, the process is reversed for further handling.
[0043] This invention, through the installation of a lifting mechanism, eliminates the need for workers to bend excessively during placement and handling when the second support shell is moved to the top, reducing labor intensity and increasing handling efficiency. When the second support shell is moved to the bottom, large items are protected by vertical plates during movement, preventing collisions and damage during transportation. The clamping mechanism, when the second support shell is moved to the bottom, simultaneously moves the clamping outer plates to clamp and secure large items placed on it, preventing movement and collisions with the vertical plates during transport. The moving mechanism, when the second support shell is moved to the top and the clamping outer plates are released, allows rollers to be moved, facilitating the placement of large items for movement by workers, further reducing labor intensity and increasing the device's practicality. This invention has a simple and reliable structure, provides good handling performance in logistics transportation, is easy to control, and is suitable for widespread application.
