Description

Technical Field

[0001] The utility model relates to the technical field of lifting tables, in particular to a stepless flip lifting table. Background Art

[0002] Desks and chairs are essential equipment in primary and secondary schools, where children and adolescents spend the majority of their learning and life. Proper desks and chairs play a significant role in fostering correct sitting habits, reducing spinal curvature and myopia, and improving learning and performance.

[0003] Because students vary in height, schools can't customize desks to their needs. Lift-and-slide tables offer a solution, making them popular. Initial lift-and-slide tables omitted drawers to prevent tipping, and their flat surface was used to stack textbooks, making them difficult for teenagers to do homework or nap. Researchers have developed flip desks to address this issue. However, existing flip-and-slide tables require only the entire surface to be adjusted, making it difficult to place textbooks flat on the surface. This requires further improvement.

The angle of the flip table top can be adjusted by the table top flipping mechanism to adapt to the writing of students of different heights, as well as the comfortable angle required for lying down during lunch break, meeting the multiple needs of students.

[0007] Preferably, the tabletop of the flip tabletop is flush with the tabletop of the flat tabletop in a flat state.

[0008] Preferably, the tabletop flip mechanism includes a tabletop flip assembly mounted at both ends, the assembly comprising a fixed hinged plate, a stepless adjuster, a flip connection plate, and a flip lever.

[0009] As an improvement, a linkage rod is connected between the table top flipping components, and the two ends of the linkage rod are respectively connected to the flipping rod. The table top flipping components at both ends can be adjusted simultaneously through the linkage rod, which facilitates the flipping operation of the flipping table top.

[0010] Preferably, the fixed hinge plate includes a fixed portion and a hinge portion, the hinge portion is annular, and the adjustment shaft of the stepless adjuster is inserted into the shaft hole of the hinge portion, so as to prevent the fixed hinge plate from interfering with the flipping operation of the flip table.

[0017] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of the present application and are not intended to limit the scope of protection of the embodiments of the present application. Those skilled in the art may adjust them as needed to suit specific application scenarios.

[0018] This embodiment is a stepless tilt lift table. Figures 1 to 3 As shown, the table comprises two lifting columns 1, two table legs 2, a drive box 3 for the lifting columns 1, a support beam 4 connecting the upper ends of the two lifting columns 1, a support frame 5 fixed to the front of the support beam 4, and a flat table top 6 fixed to the support frame 5. The support frame 5 is also mounted with a table top flipping mechanism 8, which is mounted on a flip table top 7 connected to the rear of the flat table top 6. If the ends of the support beam 4 are short square rods, the table top flipping mechanism 8 can also be mounted on the short square rods of the support beam 4.

[0019] Preferably, the tabletop of the flip table top 7 is flush with the tabletop of the flat table top 6 in a flat state.

[0020] Preferably, the table top flipping mechanism 8 includes table top flipping components respectively mounted on the longitudinal bars at both ends of the support frame 5 , and a linkage rod 86 is connected between the table top flipping components.

The fixed hinge plate 81 includes a fixed portion and a hinged portion. The fixed portion is in the shape of a zigzag and is fixed to the longitudinal rod of the support frame 5 by bolts. The hinged portion is annular, and the adjustment shaft of the stepless adjuster 82 is inserted into the axial hole of the hinged portion. The flip connecting plate 83 is also in the shape of a zigzag. The upper flat plate of the flip connecting plate 83 is fixed to the flip table 7. The stepless adjuster 82 is arranged between the hinged portion of the fixed hinge plate 81 and the lower vertical plate of the flip connecting plate 83.
