A butterfly-hole shelf

Abstract

This utility model discloses a butterfly-hole shelving unit, which includes uprights connected by P-shaped tubes. A raised structure is formed on the inner side of the P-shaped tube, and a shelf is placed on the raised structure. Column clips with L-shaped cross-sections are connected to both ends of the P-shaped tube. The uprights include columns, and the column clips are attached to adjacent surfaces of the columns. Multiple first butterfly holes are spaced along the length of the column, with first spring clips formed on the inner side of each first butterfly hole. Second butterfly holes are formed on the column clips, with second spring clips formed on the inner side of each second butterfly hole. The second spring clips can pass through the first butterfly holes, move downwards, and engage with the lower end of the first butterfly hole. The first spring clips press the second spring clips firmly against the inner side of the column. This design solves the problems of existing shelving units where the beams rely solely on lugs to engage with wedge-shaped holes, resulting in insufficient stability and difficulty in disassembling and assembling the entire shelving unit.

Description

Technical Field

[0001] This utility model relates to the field of warehouse logistics racking, specifically to a butterfly hole racking. Background Technology

[0002] Shelving is commonly used in warehousing and logistics. For example, Chinese patent CN99220599.9 provides a warehouse shelving system with uprights, beams between the uprights, shelves between the beams, and connecting rods between the uprights on both sides. The ends of the connecting rods are welded to the uprights, and the lugs at both ends of the beams engage with wedge-shaped holes on the uprights. Shelving systems like the one described above rely solely on lugs engaging with wedge-shaped holes at the ends of the beams, resulting in insufficient stability and making the entire shelving system difficult to disassemble and assemble.

[0005] The two ends of the P-shaped tube are respectively connected to column clamps, and the cross-section of the column clamps is L-shaped;

[0006] The frame includes columns, and the column clips are attached to two adjacent surfaces of the columns;

[0007] The column has a plurality of first butterfly holes spaced apart along its length. A first spring is formed inside the first butterfly hole. The column clip has a second butterfly hole. A second spring is formed inside the second butterfly hole, so that the second spring can pass through the first butterfly hole and move downward to engage with the lower end of the first butterfly hole. The first spring presses the second spring tightly against the inner side of the column.

[0008] Preferably, a first pin hole is formed between two adjacent first butterfly holes, and a second pin hole is formed on the pin holder, with the safety pin passing through the second pin hole and the first pin hole in sequence.

[0009] Preferably, the uprights further include horizontal braces and diagonal braces; the two uprights are connected by the horizontal braces and the diagonal braces respectively.

[0010] Preferably, the plurality of horizontal braces and the plurality of diagonal braces are staggered along the length of the column.

[0011] Preferably, the bottom surface of the layer is formed with a groove, and a plurality of reinforcing ribs are provided in the groove.

[0012] Preferably, the edge of the groove is formed with an annular portion, and the cross-section of the reinforcing rib is a trapezoidal open structure;

[0013] A connecting portion is formed at the trapezoidal opening of the reinforcing rib;

[0014] The connecting part is welded to the bottom surface of the layer plate, and the two ends of the reinforcing rib are engaged between the annular part and the bottom surface of the layer plate.

[0015] Beneficial Effects: This utility model provides a butterfly hole shelf, which includes uprights connected by a P-tube; a raised structure is formed on the inner side of the P-tube, and a shelf is placed on the raised structure; column clips are connected to both ends of the P-tube, and the column clips have an L-shaped cross-section; the uprights include columns, and the column clips are attached to the two adjacent surfaces of the columns; a plurality of first butterfly holes are spaced along the length of the columns, and a first spring is formed on the inner side of the first butterfly holes; a second butterfly hole is formed on the column clip, and a second spring is formed on the inner side of the second butterfly hole, so that the second spring can pass through the first butterfly hole, move downward and engage at the lower end of the first butterfly hole, and the first spring presses the second spring against the inner side of the column. The butterfly-hole shelving provided by this utility model involves setting two uprights at intervals during installation. Then, the column clips at both ends of the P-tube are attached to the uprights of the uprights. When installing the column clips, the second spring is inserted into the upper end of the first butterfly hole and then moves downwards, causing the second spring to engage at the lower end of the first butterfly hole. After engagement, the first spring presses the second spring tightly against the inner side of the upright. This fixing method ensures that the higher the load-bearing capacity of the P-tube, the tighter the engagement, preventing the column clips from shifting horizontally and detaching from the upright. The shelves are then placed on the protruding structure of the P-tube. The butterfly-hole shelving provided by this utility model is easy to install and disassemble, and the P-tube is tightly connected to the upright, ensuring high storage security.
