[0018] like Figure 1-2 As shown, the utility model discloses a support leg for resisting lateral thrust, comprising a base 1, wherein the left and right sides of the base 1 are bent downward to form a lower flange 11, the lower flange 11 is obliquely arranged to form a conical opening, a side bracket 2 is symmetrically installed on the base 1, the side bracket 2 and the base 1 are connected by welding, a through hole 21 is correspondingly processed in the middle of the side bracket 2, the shaft 3 passes through the through hole 21 and is axially limited by a limiting bolt 33, the edge of the through hole 21 is axially extended to form a flange hole 211, and the flange hole 211 is arranged on the side bracket On the side opposite to the frame 2, a rotating sleeve 4 is provided between the side brackets 2 and the shaft 32 of the rotating shaft 3. The left side of the rotating shaft 3 is fixedly connected to the head 31. The outer peripheral surface of the rotating sleeve 4 is fixedly connected to the lower part of the support 5. The front and rear sides of the side bracket 2 are bent to form a side flange 22. The bending angle of the side flange 22 is between 30° and 90°. The side flange 22 and the flange hole 211 are arranged on the same side. An integrated limit block 23 is provided at the bottom of the side bracket 2. The limit groove 12 is processed correspondingly on the base 1. The limit block 23 cooperates to extend into the limit groove 12 (see Figure 3-5 ).

[0019] In the leg structure, the side bracket is designed to be a U-shaped structure, and a limit block and a limit groove are correspondingly arranged between the side bracket and the base. The processing technology is simple, the positioning is convenient and accurate, the connection structure between the side bracket and the base is more stable, and the side thrust resistance of the side bracket in the front and rear and left and right directions is greatly increased, which effectively improves the supporting bearing capacity; obliquely distributed lower flanges are provided on the left and right sides of the base, and the stability of the base is improved; a flange hole is formed at the edge of the through hole on the side bracket for connecting the rotating shaft, which increases the contact area with the surface of the rotating shaft, and the connection structure between the rotating shaft and the side bracket is more stable.

[0020] During the specific processing, in order to facilitate the understanding of the utility model, the following description is given in conjunction with the accompanying drawings;

[0021] The legs of the utility model are provided with side-flapping structures on the front and rear sides of the side bracket to form a U-shaped structure, so that the contact area between the side bracket and the base is increased. Compared with the straight connection structure of the flat side bracket, the U-shaped connection structure is more stable, and the side bracket's resistance to lateral thrust in the front and rear and left and right directions is greatly increased.
