DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(9) Combining the figures, the following further explains the technical solution of the present invention in details by specific embodiments.

(10) A storage shelf (see FIG. 1) comprises upright posts 1, transverse beams 2 and shelf boards 3. There are four upright posts, whereon connected are two ends of the transverse beams; four transverse beams form a layer, and a shelf board is placed on the transverse beams for each layer. A storage shelf may have multilayers according to the need; and the distance between the layers is variable.

(11) Two rivets 6 are fixed on both ends of the transverse beams respectively (see FIGS. 2, 3, 4, 7), serving as the connecting parts to the upright posts, the two rivets on the same end are arranged in up-down structure; a gap is reserved between the rivet head plane and transverse beam surface, and the gap is of the thickness of the upright post sheet. In addition to rivet, the connecting parts can be other ways that are available for clamping, for example, hook, etc.

(12) A first reinforcement rib 4 is provided along the length direction between the upper rivet and lower rivet on the transverse beam, and the first reinforcement rib is best located in the middle of the transverse beam, making it uniformly forced. Two ends of the first reinforcement rib are inclined ends 5; the inclined angle of the inclined end is not larger than 45, in this way, the interference between the ends of the transverse beams when connecting with the upright posts can be avoided.

(13) The first reinforcement rib consists of an inclined part 9 and a transverse part 8, the upper surface of the transverse part is a supporting surface, and a shelf board is placed on the supporting surface. The transverse part is tabular shaped, and the supporting surface is a supporting plane; the inclined part is tabular shaped, and round bend is adopted between the transverse part and the inclined part. The distance between the supporting surface of the first reinforcement rib and the upper edge of the transverse beam matches the thickness of the shelf board, and the rivet head and the first reinforcement rib are placed on both sides of the transverse beam main plane respectively.

(14) In another preferred embodiment, the first reinforcement rib consists of upper and lower inclined parts (see D in FIG. 5), the slope of the lower inclined part is larger than that of the upper inclined part; the first reinforcement rib slopes upward, and the bend angle between the two inclined parts serves as the supporting angle of the shelf board, such structure is more resistant to slope down due to deformation. Wherein, the angle between the upper inclined part of the two inclined parts and the transverse beam main plane is between 60-85.

(15) The transverse part or inclined part mentioned above can be either tabular shaped or arc shaped, and the design of rounded corner is preferably adopted at the folding corners.

(16) It can be seen in FIG. 4 that in this embodiment, a second reinforcement rib 7 is provided on the upper side of the transverse beam downwardly folding 180, and the lower side of the transverse beam is straight. However, other three preferred embodiments are given by A, B, C in FIG. 5. In A, the lower side of the transverse beam has a third reinforcement rib folding 90; in B, in addition to folding 90, the lower side of the transverse beam further has a fourth reinforcement rib upwardly folding 90 adjacent to the edge; in C, the lower side of the transverse beam has an arcuate projection serving as a fifth reinforcement rib.

(17) The upright post includes two right-angled planes, whereon multiple clamp holes 10 are provided (see FIGS. 6 and 7), the clamp hole is a combination of a big circular hole and a small circular hole interconnected with each other. The distances between the clamp holes on the same upright post are uniformly distributed, the distance between the centers of two adjacent small circular holes is the distance between the centers of the two rivet heads on the same end of the transverse beam; the diameter of the big circular hole is larger than that of the rivet head; the diameter of the small circular hole is between the diameters of the rivet head and the rivet rod, or preferably, the diameter of the small circular hole equals to the diameter of the rivet rod.

(18) The transverse beams connect with the upright posts by rivets clamping into the clamp holes, after connection, the first reinforcement ribs relatively face toward the inner position, adjusting the length of the transverse beam can change the length and width of the storage shelf, and apply to shelf boards with different length and width. The transverse beams in the same layer connect into the clamp holes with the same height on the upright posts, and by adjusting the height of the four transverse beams in the same layer on the upright posts, the distance between the layers can be changed.

(19) The foregoing described the preferred embodiments of the present invention. It should be understood that an ordinary one skilled in the art can make many modifications and changes according to the concept of the present invention without creative work. Therefore, any technical solutions that can be obtained by a person skilled in the art depending on the concept of the present invention on the basis of the prior art through logical analysis, reasoning or limited experiments, should all fall in the protection scope defined by the claims.
