DETAILED DESCRIPTION

[0017] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0018] like Figure 1-2 As shown, this embodiment provides an elliptical frame folding structure, including a base 1, two columns 2 and a limit member 3.

[0019] The base 1 includes a fixed seat 11 and a folding seat 12. The fixed seat 11 includes a main pipe and four side pipes. The column 2 is located on the main pipe. Two side pipes are connected to the two sides of the fixed seat 11 respectively. An extension seat is formed on the outward side of the side pipe away from the folding seat 12. The side of the extension seat has a first rotating shaft. Two columns 2 are located on the upper surface of the fixed seat 11 and are arranged at intervals. A first frame 21 is formed between the upper surface of one column 2 and the side of the other column 2. A second frame 22 is formed on the upper side of the column 2 close to the folding seat 12 facing the folding seat 12.

[0020] The fixed seat 11 has a hinged frame 111 on one side facing the folding seat 12, and a locking hole 1112 is provided at the bottom of the hinged frame 111. The folding seat 12 has a threaded hole extending from top to bottom, and the threaded hole corresponds to the locking hole 1112. The folding seat 12 includes a first transverse tube and a second transverse tube, and the first transverse tube is connected to the middle of the second transverse tube and is perpendicular to each other. The end of the folding seat 12 is located in the hinged frame 111 and is hinged (the first transverse tube is also hinged to the hinged frame 111). Specifically, the hinged frame 111 includes a bottom plate and two vertical plates extending upward, and the two vertical plates are connected on both sides of the bottom plate. The upper surface of one side wall of the hinged frame 111 (the upper surface of any vertical plate) has an arc-shaped protrusion, and a locking notch 1111 is formed on the arc-shaped protrusion. The side wall of the folding seat 12 has a through hole.

[0021] The limiting member 3 includes a screw post 31 and a folding buckle 32. The folding buckle 32 is connected to the upper surface of the screw post 31. The circumferential surface of the screw post 31 has an external thread. The screw post 31 is adapted to the threaded hole. When the fixed seat 11 and the folding seat 12 are flush (in the lowered use state), the folding buckle 32 is opened and rotated so that the screw post 31 is screwed into the locking hole 1112. At this time, the folding seat 12 cannot be folded and is limited by the locking hole 1112.

[0022] A telescopic column 122 and a driving assembly are provided in the folding seat 12, and the driving assembly drives the telescopic column 122 to extend out of the through hole and adapt to the locking notch 1111. Specifically, the upper surface of the folding seat 12 has a clearance notch 121. The driving assembly includes a moving seat and a limiting slide rail. The limiting slide rail is located inside the folding seat 12 and faces the through hole. The moving seat is adapted to the limiting slide rail. The telescopic column 122 is connected to the side of the moving seat facing the through hole. A toggle plate 123 is formed on the moving seat, and the toggle plate 123 extends out of the clearance notch 121. The folding principle is: first, the rotating column 31 is rotated away from the locking hole 1112, and the folding seat 12 is folded upward. When it is folded into place, the toggle plate 123 on the moving seat is toggled to make the moving seat move, drive the telescopic column 122 to extend out of the through hole and snap into the locking notch 1111, so as to achieve folding and limiting.
