Example 1

Referring to fig. 1 and 2, the folding table comprises two mutually foldable plate bodies 1 and a supporting component 2 which is folded and accommodated on each plate body 1; the two plate bodies 1 are hinged through a hinge assembly 3 so that the two plate bodies 1 can be mutually folded; the support assemblies 2 are connected to the plate body 1, two groups of support assemblies 2 on the same plate body 1 are arranged, and the two support assemblies 2 on the same plate body 1 are symmetrically arranged; when the two plate bodies 1 are unfolded, the two plate bodies 1 form a table plate of the folding table together, the four groups of support assemblies 2 are respectively positioned at four corners of the table plate, and the four groups of support assemblies 2 are arranged on the table plate in a mirror symmetry mode, so that after the four groups of support assemblies 2 are completely unfolded, the two adjacent support assemblies 2 in the transverse direction or the two adjacent support assemblies 2 in the longitudinal direction are splayed and spread, and the stability of the unfolded table plate is improved.

Referring to fig. 2 and 3, each group of support members 2 includes a table leg 21 hinged to the surface of the plate body 1 and a stopper 22 connected between the table leg 21 and the plate body 1; the surface of the plate body 1 is fixedly connected with a mounting seat 11 and a sliding seat 12 which are arranged at intervals, and the extension lines of the ends of the mounting seat 11 and the sliding seat 12 which are close to each other are not in the same straight line; one corner of the mounting seat 11 is bent with a hinge part 111 perpendicular to the plate body 1, and one side of the table leg 21 is hinged with the hinge part 111 at one end of the table leg 21 close to the plate body 1; specifically, the leg 21 is movably riveted to the hinge 111 by a rivet.

Referring to fig. 2 and 3, an extension portion 121 perpendicular to the plate body 1 is bent at one side of the sliding seat 12, a long hole 1211 and a clamping hole 1212 are formed in the extension portion 121, the length direction of the long hole 1211 is consistent with the length direction of the extension portion 121, and the clamping hole 1212 is communicated with one end of the long hole 1211 away from the mounting seat 11; the limiting part of the limiting piece 22 is slidably connected with the long hole 1211, and the limiting part of the limiting piece 22 is clamped with the clamping hole 1212.
