The pin 11 is in the form of a flat pin, since the width at the third guide groove 12c also only allows the pin 11 to pass in the flat direction, thus preventing the flat pin 11 from being returned to the second guide groove 12b due to bumps during transportation. The wall panels 3, 4 cannot be opened normally, and at the same time, the side wall panels 3, 4 can only be rotated when the pin 11 is at the fourth guiding groove 12d, and are in the first guiding groove 12a, the second guiding groove 12b, The third guide groove 12c must be kept in a direction perpendicular to the bottom plate 5 to avoid dumping due to an external force such as wind force or inadvertent collision.

Similarly, another form of corner post 10:

As shown in Fig. 9, the guide groove 12 on the corner post 10 can also be opened as shown, and is suitable for a place where the side wall panels 3, 4 need to be removed. The open end 121 of the guide groove 12 is located at the top of the corner post 10, and the upright position 122 is sequentially connected through a vertically disposed second guide groove 12b, a horizontally disposed third guide groove 12c, and a vertically disposed fourth guide groove 12d. To the folded position 123, the open end 121 communicates with the third guide groove 12c through a vertically disposed first guide groove 12a, thereby communicating the upright position 122 and the folded position 123. Wherein, the width of the first guiding groove 12a also only allows the pin 11 to pass in the flat direction, that is, the side wall panels 3, 4 must be maintained at an angle to the bottom plate 5, and this angle should be fixed to the side of the pin 11 It has already been determined on the wall panels 3, 4 (the illustration is parallel). The side wall panels 3, 4 are horizontally placed, and the flat pins 11 pass through the first guiding grooves 12a in the flat direction, and can be rotated in the flat direction after being rotated to the vertical state at the intersection of the first guiding grooves _12a and the third guiding grooves _12c . The three guide grooves 12c are moved to the upright position 122 or the folded position 123. In the upright position 122, the side wall panels 3, 4 are in a vertically assembled state, and in the folded position 123, the side wall panels 3, 4 are Fold inward on the end frame panels 1, 2. When transported at no load (ie, the side panels 3, 4 are in a folded state), The side wall panels 3, 4 are placed at an angle approximately parallel to the bottom plate 5, and the pin 11 is at the fourth guide groove 12d, at which time the size of the third guide groove 12c is limited, so that the pin 11 cannot be returned to the guide groove 12a. Therefore, it is ensured that the side wall panels 3, 4 do not come out of the bottom plate 5.

In the above embodiment, the bottom plate and the end wall panel and the side wall panel are both in the form of a cover plate, as shown in Fig. 10, or in the form of a grid, for containing goods such as fruits and vegetables. Moreover, if necessary, the utility model can also add a top cover, which is not shown in the figure.

Of course, the present invention may be embodied in various other forms and modifications without departing from the spirit and scope of the invention. These respective changes and modifications are intended to fall within the scope of the appended claims.
