Description

Technical Field

[0001] This utility model relates to the field of table leg structure technology, and in particular to a table leg structure that is anti-shaking and can be quickly folded. Background Technology

[0002] The existing patent publication number (CN118872958A) discloses a folding stand and folding table with rapidly increasing height. It includes a first table leg and a second table leg arranged opposite each other. The bottom end of the first table leg has a first adjusting rod that can be flipped to adjust the height, and the bottom end of the second table leg has a second adjusting rod that can be flipped to adjust the height. It also includes a first support rod and a second support rod. By simultaneously flipping the first and second adjusting rods outwards to a vertical position, the folding stand can be rapidly increased in height. Furthermore, the first and second support rods can also simultaneously rotate to a straight line after the first and second adjusting rods have rotated to a vertical position.

[0003] However, its ease of storage and folding is average, and its structural stability when unfolded is also average.

[0004] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0005] A wobbly, quick-folding table leg structure includes a table leg, two symmetrical adjustable side panels, and a quick-adjustment bracket. The adjustable side panels are symmetrically paired with one table leg. The adjustable side panels are fixed to the tabletop by screws or rivets. Each adjustable side panel is provided with an arc-shaped groove with a corresponding angle of 90 degrees. A quick-press screw lock is provided through the arc-shaped groove and extends into the table leg. Pressing the quick-press screw lock secures the adjustable side panel to the table leg, thus locking them in place.

[0006] Preferably, the gear adjustment side plate is provided with a table leg travel groove, and at the end of the table leg travel groove, there is a drop with a depth greater than the diameter of the quick-press screw lock. When the quick-press screw lock moves to the end of the table leg travel groove, it slides into the drop groove to pre-position itself, and then the quick-press screw lock is pressed to achieve final positioning and fixation.

[0007] Preferably, the gear adjustment side plate is further provided with a quick adjustment frame travel groove and a pulley travel groove for the long shaft pin and roller to be movably arranged on the gear adjustment side plate, respectively. The long shaft pin passes through the table leg and is fixed at both ends to the two sides of the quick adjustment frame. The long shaft pin passes through the second pin hole on the quick adjustment frame. In addition, the quick adjustment frame is also provided with a first rotating pin hole. The first rotating pin hole is rotatably connected to the gear adjustment side plate by a pivot pin. In this way, when the quick adjustment frame applies force to one end of the second pin hole in the direction of the arrow as shown in the figure, the long shaft pin lifts the table leg upward, causing the quick-press screw to leave the drop groove at the end of the table leg travel groove, which facilitates the table leg to be flipped and folded.

[0008] Preferably, a torsion spring is fixed to the gear adjustment side plate by screws. One end of the torsion spring is pressed on the roller to move it to the end of the pulley travel groove near the travel groove of the quick adjustment frame. The quick adjustment frame is provided with gear two and gear one for engaging with the roller, as shown in the figure. When the table leg is in the unfolded and locked state, the roller and gear two are engaged.

[0009] Preferably, in order to improve the synchronization of the two rollers mounted on the gear adjustment side plate and improve the smoothness of operation, a connector is also included, the two ends of which are rotatably connected to the shaft end of the roller.

[0010] The advantages and positive effects of this utility model are:

[0011] 1. Through the ingenious design of the fixed plate's arc-shaped sliding groove and recess, the manual pressing plate operation to achieve two states of table legs (upright and folded), and the spring return positioning of the movable positioning plate to achieve two positions, the system achieves both rapid folding and stability when the table legs are upright. Compared with existing technologies, it greatly improves convenience and reduces the difficulty of operation. Attached Figure Description
