The supporting plate 43 is arranged on the back side of the hinge device 1 by utilizing the structure of the outer bottom side beam 3 of the folding container, and the back side of the hinge device 1 is the outer side thereof along the length direction of the folding container. The supporting plate 43 is located at the gap of the outer bottom side beam 3 close to the hinge device 1, and the side edge thereof is welded to the hinge device 1, and is welded to the outer bottom side beam 3 through the supporting plate 44. The supporting plate 43 is in the same height as the upper surface of the outer bottom side beam 3, and is provided with a notch 45, and the width of the notch 45 can be referred to the corner piece plate 2.
[0021] The connecting rod 42 comprises a first straight rod 421, a second straight rod 422 and a third straight rod 423 which are in the same plane and are sequentially connected in a head-to-tail mode, wherein the second straight rod 422 is perpendicular to the first straight rod 421 and the third straight rod 423, the end of the third straight rod 423 is fixed with the torsion lock 41, and the end of the first straight rod 421 is rotationally connected to the outer side of the hinge device 1.
[0022] The outer side of the hinge device 1 is provided with a shaft sleeve 46 which is a cylindrical structure with one end being an opening and the other end being a baffle. The shaft sleeve 46 is vertically welded to a fixed plate 47 which is welded to the back side of the hinge device 1 and is provided with a circular hole, and the opening of the shaft sleeve 46 is aligned with the circular hole.
[0023] The end of the first straight rod 421 is welded to a rotating shaft 48, and the first straight rod 421 is tangent to the rotating shaft 48. The axes of the shaft sleeve 46 and the rotating shaft 48 are parallel to the width direction of the folding container and are perpendicular to the length direction of the folding container. The radius of the rotating shaft 48 is smaller than the inner diameter of the shaft sleeve 46, the rotating shaft 48 passes through the circular hole, the shaft sleeve 46 is sleeved on the rotating shaft 48, and the rotating shaft 48 can rotate around its axis in the shaft sleeve 46 to realize the overturning of the connecting rod 42 and the torsion lock 41, and the overturning direction is along the width direction of the folding container.
[0024] According to the relative position relationship between the connecting rod 42 and the rotating shaft 48, when the rotating shaft 48 rotates, the horizontal position of the first straight rod 421 and the connecting rod 42 will change in the height direction, and when the connecting rod 42 is in the horizontal position, the rotating shaft 48 rotates 180 degrees to make the connecting rod 42 again in the horizontal position, but the horizontal heights of the two positions are different by a diameter distance of the rotating shaft 48.
[0025] By using the above structure, in the rotating process of the connecting rod 42, the torsion lock 41 falls to the corner piece plate 2 and the supporting plate 43 respectively to form the use state and the storage state of the torsion lock 41.
