Detailed Description

In order to further understand the technical solution of the present invention, the present invention is further explained by the following embodiments with reference to the attached drawings.

As shown in fig. 1, the multiple shelf 1 of the present embodiment includes an upper panel 7 and a lower panel 3, etc. which are fitted to face each other. The opposite sides and two ends of the upper panel 7 are respectively provided with a single lower vertical edge 9 protruding downwards. The relative both ends of lower panel 3 are equipped with respectively and connect in opposite directions each other with the single lower vertical limit 9 in both ends of upper panel, upwards convex single vertical limit 5, the relative both sides of lower panel 3 are equipped with respectively and erect limit 3a on the spill, its spill is erect the limit and is a recess shape of downward open-ended for a cross sectional shape, the single lower vertical limit in both sides of upper panel is located the inboard of the spill of lower panel and erects limit 3a, the single lower lateral wall that erects the limit in both sides of upper panel and two spill upper two inside walls that erect the limit of lower panel mutually contact cooperation and be connected, and the single lower level that erects the limit in both sides of upper panel and the internal face contact of lower panel are connected. The concave upper vertical edge of the lower panel 3 is formed by continuously folding the corresponding lower panel body for three times in the same direction. It has great mechanical strength. The opposite two sides of the upper panel are respectively provided with a downward inner coupling edge 7b, and the concave upper vertical edge 3a of the lower panel is provided with a downward outer coupling edge 3b correspondingly connected with the inner coupling edge of the upper panel in parallel. The inner coupling edge and the outer coupling edge are inclined towards each other from top to bottom. It can realize the no connecting piece self-adaptability and the tight fit of upper and lower panel. And the blade part of the interface can be avoided.

The upper wall surface of the upper panel is flush with the upper wall surface of the concave upper vertical edge at two opposite sides of the lower panel to form a bin bottom plate of the corresponding storage bin, and the lower wall surface of the lower panel forms a lower storage space top plate, so that the taking and storing operation of articles is facilitated. The upper panel and the single lower vertical edge thereof, the lower panel and the concave upper vertical edge thereof and the single upper vertical edge thereof are respectively bent into a whole by corresponding metal plates.

An integrated ear-shaped reinforcing device is arranged in an inner space formed between the upper panel and the lower panel, the integrated ear-shaped reinforcing device is an open type supporting plate 10 with an inverted-handle-ear-shaped cross section, the open type supporting plate comprises a bottom plate supported on the inner wall surface of the lower panel, and 7-shaped supporting edges 10a which are respectively connected with two opposite sides of the bottom plate 10b and supported on the inner wall surface of the upper panel. The opposite ends of one side of the lower panel close to the front of the frame body are respectively provided with a plug-in body 6 formed by the opposite ends of the concave upper vertical edge of the lower panel in a protruding way.

The plug-in body of the double shelf can be connected with the upright post or the side wall plate of the corresponding frame body, and the two opposite ends and the rear side of the double shelf can be connected with the corresponding side wall plate of the frame body by self-tapping screws, gun nails and the like.

In example 2. The butt joint seam of the single lower vertical edge and the upper vertical edge at the two ends of the upper panel and the lower panel of the composite shelf is fixedly connected by welding. The rest of the structure and the corresponding connection mode of this example can be similar to the above-mentioned embodiment.

The inner coupling edges 7b at two sides of the upper panel are provided with the arched bags 12, the outer coupling edges 3b of the lower panel are provided with the concave parts 11 corresponding to the arched bags 12, and the upper panel and the lower panel are in limited connection with each other through the arched bags and the corresponding concave parts. The rest of the structure, the corresponding connection mode and the like of the present example can be similar to any of the above embodiments.

In example 4. The opposite two ends of the lower panel close to the rear side of the frame body are respectively provided with a reinforced connecting convex body which is approximately saddle-shaped, and the reinforced connecting convex body is formed by partially protruding one side of the vertical wall surface close to the outer side of the concave upper vertical edge. The reinforced connecting convex body can be connected with the coamings or the rear upright posts at two opposite sides of the frame body.
