The rear baffle 85 is fixed by the fixing groove 68 on the shelf 6 at the lowest part of the shelf, the first positioning groove 81 on the side bar 11 and the second positioning groove 82 on the bottom bar 21.

The groove widths of the limiting groove 642 and the fixing groove 68 are the same as the thickness of the fixing plate 65, the width of the fixing plate 65 is the same as the distance between two adjacent shelves 6, and the length of the fixing plate 65 is the same as the distance between two side frames 1.

The both ends of layer pole 61 are provided with fourth layer pole fixed orifices 69 with fourth layer pole inserting and connecting portion 71 looks adaptation, and layer pole 61 is connected with fourth connecting portion 72 through the cooperation of fourth layer pole inserting and connecting portion 71 and fourth layer pole fixed orifices 69.

Wherein, the fourth layer pole fixed orifices 69 that are located on the layer pole 61 of shelf front end and both sides are the L shape to avoid the standing groove 63 on the layer pole 61, the cross section of connecting the fourth layer pole inserting part 71 that is located the layer pole 61 of shelf front end and both sides also is the L shape, and the cooperation of fourth layer pole inserting part 71 and fourth layer pole fixed orifices 69 is connected with fourth connecting portion 72.

Wherein, the fourth layer pole fixed orifices 69 that are located on the layer pole 61 of shelf rear end are two diamond holes to avoid standing groove 63 and fixed slot 68 on the layer pole 61, connect the fourth layer pole grafting portion 71 that is located the layer pole 61 of shelf rear end and be two grafting posts, two grafting posts and the cooperation in two diamond holes are connected with fourth connecting portion 72.

Referring to fig. 27, the angle between the upper rod insertion part 191 and the lower rod insertion part 192 may be an obtuse angle, the length of the layer rod 61 and the layer plate 62 between the side rod 11 and the upper rod 14 at the rear end of the shelf gradually decreases with the increase of the height, and the side surface of the space-avoiding notch 74 in the fourth connecting part 72 of the layer rod 61 is an inclined surface having the same inclination angle as the upper rod 14, so that the layer shelf 6 is close to the upper rod 14, thereby improving the support strength and stability of the shelf.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
