[0034] Example 1

[0035] Figure 1-2The figure schematically shows a foldable support leg structure according to an embodiment of the present invention.

[0036] like Figure 1-2 As shown, the foldable supporting leg structure includes a main rod 1, a load-bearing part 2 and a linkage part 3. The first end of the linkage part 3 is movably connected to the main rod 1, and the second end is movably connected to the first end of the load-bearing part 2. The second end of the load-bearing part 2 is movably connected to the main rod 1. The load-bearing part 2 can change between two states: perpendicular to the main rod 1 and parallel to the main rod 1.

When not in use, it can be folded so that the load-bearing part 2 is parallel to the main pole 1, saving space and being easy to store.

[0048] Example 2

[0049] Figure 3 A drying device according to one of the embodiments of the above-mentioned embodiment 1 is schematically shown.

[0050] like Figure 3 As shown, the drying device includes a drying rack body 200 and windproof support legs arranged at the bottom of the drying rack body 200.

[0057] like Figure 4-5 As shown, the side of the main rod 1 of this embodiment is provided with a limiting groove 12 that is limited and matched with the load-bearing part 2 and the linkage part 3. The limiting groove 12 is formed by two extension pieces 11 provided on one side of the main rod 1. After folding, the load-bearing part 2 and the linkage part 3 can be accommodated in the limiting groove 12, and the main rod 1 is provided with a slide groove 111 extending along the length direction of the main rod 1 and connected to the limiting groove 12.

[0059] Specifically, the limiting portion 9 of this embodiment includes a limiting piece 91 provided in the sliding groove 111 for limiting engagement, and an inner turning groove 93 provided in the main rod 1 and limiting engagement with the limiting piece 91 , wherein the inner turning groove 93 is communicated with the sliding groove 111 .

[0060] Furthermore, the limiting member 91 and the first pin shaft are the same component.

[0061] When the limiting member 91 slides from the sliding groove 111 into the inner turning groove 93, the load-bearing part 2 is opened to a state perpendicular to the main rod 1. At this time, the linkage part 3 forms an oblique support rod, which cooperates with the limiting member 91 to limit the load-bearing part 2.

[0062] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
