[0022] Specifically, when it is necessary to lift goods, the motor 4 can be started according to the width of the goods. It drives the lead screw 5 to rotate. The rotation of the lead screw 5 causes the moving plate 6 to slide in the first slot 3 opened in the support plate 2. During the sliding process, the limiting plate 20 located on the outer surface of the moving plate 6 slides in the sliding groove 19 opened on the inner surface of the first slot 3 to prevent the moving plate 6 from moving out of the second slot 3. The moving plate 6 drives the vertical plate 9 to rotate on the rotating rod 8. The vertical plate 9 supports the moving plate 6. After adjusting to a suitable position, the motor 4 stops.
[0023] Reference Figure 1 and Figure 2The outer surface of the movable plate 6 is fixedly connected to a lower hanging plate 11. The lower hanging plate 11 is provided with a second slot 12. The lifting device body 13 is movably connected in the second slot 12. The outer surface of the lifting device body 13 is provided with an insertion slot 14. The outer surface of the lower hanging plate 11 is rotatably connected to an insertion rod 15.
[0024] Specifically, after the movable version 6 is moved to the appropriate position, the lifting device body 13 is pulled, causing it to slide within the second slot 12 of the lower lifting plate 11. When the lifting device body 13 is lowered to the appropriate height, the lifting device body 13 is fixed by inserting the insertion rod 15 into the insertion slot 14. Goods are then lifted using the lifting device body 13.
[0025] Operating principle: When it is necessary to lift goods, the motor 4 can be started according to the width of the goods. It drives the lead screw 5 to rotate. The rotation of the lead screw 5 causes the moving plate 6 to slide in the first slot 3 opened in the support plate 2. During the sliding process, the limiting plate 20 located on the outer surface of the moving plate 6 slides in the sliding groove 19 opened on the inner surface of the first slot 3 to prevent the moving plate 6 from moving out of the second slot 3. The moving plate 6 drives the vertical plate 9 to rotate on the rotating rod 8. The vertical plate 9 supports the moving plate 6. After adjusting to the appropriate position, the motor 4 stops.
[0026] After the movable plate 6 is moved to the appropriate position, the lifting device body 13 is pulled to slide within the second slot 12 of the lower lifting plate 11. When the lifting device body 13 is lowered to the appropriate height, the lifting device body 13 is fixed by inserting the insertion rod 15 into the insertion slot 14, and the goods are lifted by the lifting device body 13.
[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings.
