Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Examples

As shown in fig. 1-8, an electric adjusting structure for supporting a leg of a seat comprises a leg supporting plate 1, a seat basin stamping part 2, a motor 3, a limiting plate 4, a toothed plate 5 and a supporting seat 6.

Shank support plate 1 is used for the support of shank, when the cushion is too short, drives shank support plate 1 through the motor and stretches out seat basin stamping workpiece 2, has lengthened the cushion in other words, plays the effect of bearing shank. The leg supporting plate 1 is provided with a sliding chute I1-1 and a sliding chute III 1-2 corresponding to the front positioning block 6-1 and the rear positioning block 6-2 of the supporting seat 6 respectively.

The limiting plate 4, the toothed plate 5 and the leg support supporting plate 1 are fixed together through 6 rivets to form a leg support supporting plate assembly, and the leg support supporting plate assembly is integrally installed at the foremost position of the seat basin stamping part 2 and pushed into the supporting seat 6 and can stretch and retract relative to the seat basin stamping part 2. The limiting plate 4 is arranged between the toothed plate 5 and the leg supporting plate 1, and the limiting plate 4 is provided with a sliding groove II 4-1 for limiting.
