[0053] When implementing it, Figure 1 and Figure 5As shown, when the table body is in the folded state and needs to be opened, the push switch 442 is pressed, the cylinder 441 starts working, and the piston rod extends. During the extension of the piston rod, the connecting rod 4312 of the first U-shaped frame 4311 is driven to slide relative to the slide groove in the direction away from the table frame 20. During the sliding of the first U-shaped frame 4311, the first connecting rod 510 and the second connecting rod 520 drive the fifth connecting rod 550 and the sixth connecting rod 560 to rotate, and the first angle α between the fifth connecting rod 550 and the sixth connecting rod 560 gradually decreases. The fifth connecting rod 550 and the sixth connecting rod 560 are rotated and closed in a direction parallel to the cross bar, thereby driving the third connecting rod 530 and the fourth connecting rod 540 to drive the second U-shaped frame 4321 to slide relative to the slide groove.

During the retraction of the piston rod, the connecting rod 4312 of the first U-shaped frame 4311 is driven to slide relative to the slide groove toward the direction close to the table frame 20. During the sliding of the first U-shaped frame 4311, the first connecting rod 510 and the second connecting rod 520 drive the fifth connecting rod 550 and the sixth connecting rod 560 to rotate, and the first angle α between the fifth connecting rod 550 and the sixth connecting rod 560 gradually increases. 50 and the sixth connecting rod 560 are cross-rotated and opened in a direction parallel to the horizontal rod, thereby pushing the third connecting rod 530 and the fourth connecting rod 540, and then pushing the second U-shaped frame 4321 to slide relative to the slide groove toward the table frame 20. During the sliding process of the first U-shaped frame 4311 and the second U-shaped frame 4321, the first table leg frame 310 and the second table leg frame 320 are driven to rotate relative to each other, and the first table leg frame 310 and the second table leg frame 320 are folded relative to the table frame 20, thereby realizing the folding and lowering of the entire folding table.

[0055] In one embodiment, if Figure 3 As shown, the desktop 10 includes a plurality of table tops 110 , and a folding device 120 is disposed between the table tops 110 , and the table tops 110 are folded or unfolded by the folding device 120 ; a turntable assembly 130 is disposed at the bottom of one of the table tops 110 , and the desktop 10 rotates relative to the table frame 20 via the turntable assembly 130 .

When the desktop 10 needs to be rotated, the screw is rotated to disengage the screw from the connecting hole 140 corresponding to the desktop 10. At this time, the desktop 10 can be rotated. After the desktop 10 is adjusted to a fixed angle, the screw is rotated upward and locked into the connecting hole 140 corresponding to the desktop 10. The desktop 10 is fixed, and then the folded desktop 10 is unfolded. The fastener 60 and the connecting hole 140 ensure the fixation of the desktop 10 after rotation, so that the desktop 10 can be relatively fixed with the table frame 20 regardless of whether it is folded or opened, and the stability of the folding table in different states is maintained. The fastener 60 and the connecting hole 140 are simple in structure and low in manufacturing cost. Preferably, the table frame 20 is also provided with a limit rod 610, and the desktop 10 is provided with a limit block 620. The limit rod 610 limits the desktop 10 to rotate only 90 degrees, prevents the desktop 10 from excessive rotation, and facilitates the fixation of the fastener 60.

[0060] In one embodiment, if Figure 6As shown, the table leg frame has at least one arc-shaped avoidance section 330, and the arc-shaped avoidance section 330 can just avoid the connecting rod 4312 when the table leg frame is folded. This makes the first table leg frame 310 and the second table leg frame 320 parallel and not skewed after folding, and can be placed stably after folding. In addition, the arc-shaped avoidance method can avoid the table leg frame and the support frame 430 from directly abutting against each other, and avoid the support frame 430 or the rod body of the table leg frame from being crushed and damaged due to the application of force after folding.

Preferably, the support rod 210 is arranged perpendicular to the cylinder 441, the support rod 210 is integrally formed with the table frame 20, and is detachably connected to the cross-link mechanism 50.

[0062] In one embodiment, if Figure 2 As shown, the bottom of the table leg frame is also provided with a plurality of pulleys 340. Preferably, there are four pulleys 340, two at the bottom of each table leg frame, and the pulleys 340 can reduce friction and can cooperate well with the cylinder 441 to complete the automatic lifting of the folding table.
