Abstract
The utility model discloses a table with double-leg folding mechanisms. The utility model comprises a table plate and two sets of double-leg folding mechanisms, wherein, the double-leg folding mechanism is composed of an assembly table leg, a connecting rod and a rotation rod. When the table leg is opened, the table leg drives the rotation rod to rotate through the connecting rod. As the rotation rod is sheathed with a torsional spring, the torsional force causes the rotation rod to rotate towards the opening direction. When the table leg is provided with a certain angle, the rotation rod rotates under the function of the torsional spring. When the rotation rod rotates with 180 DEG, the connecting rod and the rotation rod are parallel in different surfaces, the connecting rod and the rotation rod are in tensioning state and lie in dead point, and then the table leg is opened and the table leg lies in firm and reliable working conditions. When the table leg is folded, the rotation rod is firstly rotated, the rotation rod leaves the dead point position, and then the table leg can be folded. The utility model has the advantages of simple structure, convenient operation, reliable work, and simultaneous opening and folding of the two table legs.
