[0002] The lifting table can adjust the height of the tabletop, that is, the operator can control the lifting of the tabletop to meet different usage requirements.

[0003] Generally, the lifting tables on the market do not have the function of folding and storing. The existing foldable and collapsible lifting tables have complex designs in structure and are inconvenient to operate. After folding and storing, the tabletop is exposed outside and is easily scratched and damaged, thus needing improvement. Summary of the Utility Model

[0004] One technical problem to be solved by this application is to overcome the defects of the above related technologies and provide a foldable and collapsible lifting table with the tabletop stored inside.

[0005] The technical solution adopted by the utility model to solve the technical problem is as follows: A foldable and collapsible lifting table includes a tabletop and its support, a lifting column and its driving mechanism, and table legs. A first rotating structure is provided between the support and the upper end of the lifting column, and the table legs are connected to the lower end of the lifting column through a second rotating structure; after folding, the table legs are close to the tabletop of the folded tabletop, and the bottom surface of the folded tabletop is close to the lifting column.

[0006] Compared with the related technologies, the utility model has the following advantages: After folding, the table legs are close to the tabletop of the folded tabletop, and the bottom surface of the folded tabletop is close to the lifting column, and the tabletop is stored inside and is not easily scratched and damaged.

[0007] As an improvement, the first rotating structure includes a rotating shaft riveted on the upper end of the lifting column and the long rods of the support on both sides thereof, and a locking mechanism mainly composed of a rotating wrench, a limiting block, and a pin shaft. The limiting block is fixed on the side of the upper end of the outer column of the lifting column away from the rotating shaft, the pin shaft is fixed on one of the long rods of the support, one end of the rotating wrench is pivotally connected to the pin shaft, and the other end of the rotating wrench passes through the other long rod and rotates in the movable groove on this long rod; the middle part of the rotating wrench is embedded below the limiting block to be in a locked state to block the rotation of the first rotating structure, and the middle part of the rotating wrench is disengaged from below the limiting block to be in an unlocked state to release the rotation of the first rotating structure; A limiting structure is also provided between the support and the outer column of the lifting column to limit the horizontality of the tabletop. The rotation of the tabletop needs to release the restriction between the rotating wrench and the limiting block to proceed.

[0008] Preferably, the limiting structure is a first cushion block embedded in the notch at the upper end of the outer column of the lifting column, and the first cushion block is fixed to the support; or the limiting structure is a second cushion block installed on both sides of the outer column of the lifting column for respectively supporting the long rods of the support.

[0009] As an improvement, the first rotating structure further includes a spring pin disposed below the long rod movable slot to limit the rotation of the rotary wrench. It is used to limit the rotary wrench to prevent the rotary wrench from being accidentally touched and disengaging from the limit block, accidentally releasing the rotation limit of the first rotating structure, resulting in the automatic flipping of the tabletop under the action of gravity.

[0010] Preferably, the table leg is in an H shape and is composed of a horizontal plate in the middle and two vertical plates respectively connected to both ends of the horizontal plate; the second rotating structure is installed on the upper surface of one end of the horizontal plate; the support of the second rotating structure is hinged to the horizontal plate, the bottom end of the inner column of the lifting column is fixedly connected to the support, and a lug for fixing to the table leg is provided on one side of the support away from the hinge, and a knob is connected to the lug for locking the support and the table leg in the use state or the folded state.

[0021] 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.

[0022] This embodiment is a foldable and foldable lifting table, comprising a table top 1 and its bracket 2, a lifting column 3 and its drive mechanism 4, and table legs 5. A first rotating structure 6 is provided between the bracket 2 and the upper end of the lifting column 3, and the table legs 5 are connected to the lower end of the lifting column 3 via a second rotating structure 7. The table top 1 and bracket 2 are fixedly connected by bolts. The bracket 2 is a rectangular frame formed by connecting two long rods, a short rod, and a thin sheet, which is attached to the bottom surface of the table top 1. The lifting column 3 is composed of a sleeved inner column and outer column, and an inner outer column lifting mechanism. The drive mechanism 4 includes a motor 4.1 and a reduction gearbox 4.2. The reduction gearbox 4.2 is mounted on the upper portion of one side of the outer column and does not hinder the folding of the table top 1 and table legs 5. The motor 4.1 is connected to the outer column lifting mechanism through the reduction gearbox 4.2 to control the lifting of the outer column. The table legs 5 are H-shaped, consisting of a central horizontal plate and two longitudinal plates connected to the ends of the horizontal plate.

[0023] In this embodiment, the first rotating structure 6 comprises a rotating shaft 6.1 riveted to the upper end of the outer column of the lifting column 3 and to the long rods of the bracket 2 on both sides thereof, two first spacers 6.2 inserted into the notches at the upper end of the outer column of the lifting column 3, and a locking mechanism mainly composed of a rotating wrench 6.3, a pin 6.4, and a stopper 6.5. The two first spacers 6.2 are coaxially arranged, with the axes of the first spacers 6.2 being parallel to or further coplanar with the rotating shaft 6.1. The stop block 6.5 is in the shape of a "U." The vertical portion of the stop block 6.5 is fixed to the upper end of the outer column of the lifting column 3, away from the side of the rotating shaft 6.1. The pin 6.4 is fixed to one of the long rods of the bracket 2. One end of the rotary wrench 6.3 is pivotally connected to the pin 6.4. The other end of the rotary wrench 6.3 passes through the other long rod and rotates within the movable groove on the long rod. When the middle portion of the rotary wrench 6.3 is embedded below the horizontal portion of the stop block 6.5, it is in a locked state, thereby hindering the rotation of the first rotating structure 6. When the middle portion of the rotary wrench 6.3 is released from below the stop block 6.5, it is in an unlocked state, thereby releasing the rotation of the first rotating structure 6. The horizontal portion of the stop block 6.5 is in the shape of a right-angled trapezoid, with the width of the end away from the pin 6.4 being greater than the width of the end near the pin 6.4. Here, a second pad 6.7 can also be set on both sides of the upper end of the outer column of the lifting column 3 to support the corresponding long rod of the bracket 2 to limit the further rotation of the table top 1 and keep the table top of the table top 1 level, as a replacement for the two first pads 6.2 embedded in the notch at the upper end of the outer column of the lifting column 3.

[0024] As an improvement, the first rotating structure 6 further comprises a spring pin 6.6 provided below the long rod movable slot to limit the rotation of the rotating wrench 6.3.

The inner column of the lifting column 3 is fixed to the main board of the support 7.5, and the support 7.5 is provided with a lug, and a knob 7.6 for fixing the support 7.5 and the table leg 5 is plugged or screwed onto the lug.

[0026] As an improvement, the lug protrudes above the adjacent longitudinal plate, and the knob 7.6 passes through the through hole 5.1 on the adjacent longitudinal plate and is screwed to the fixing ring 5.2 welded to the bottom surface of the longitudinal plate; and a clamp 7.7 is clamped on the thread of the knob 7.6 to prevent the knob 7.6 from detaching from the support 7.5 and being lost.

[0027] The foldable lifting table of this embodiment is opened as follows Figures 1 to 5 As shown, the overall shape is a "工" shape with offset vertical stripes; in the folded state, Figures 6 to 8 As shown, the folded table legs 5 are aligned with the tabletop 1 after folding, and the bottom surface of the folded tabletop 1 is aligned with the lifting columns 3. That is, the top surface of the table legs 5 is parallel to the tabletop 1 with a gap, and the bottom surface of the tabletop 1 is parallel to the outer column surface of the lifting columns 3 with a gap. The gap is used to prevent collision. The thin sheet is provided to prevent the bottom surface of the tabletop 1 from being obstructed from approaching the outer column surface of the lifting columns 3 and to prevent collision between the bottom surface of the tabletop 1 and the outer column surface of the lifting columns 3. Of course, the thickness of the thin sheet can be increased accordingly when embedded in the tabletop 1.
