The part 24 is a coupling hole opened in the joining platform 23. A plurality of stoppers 25 are molded upward on the joining platform 23, and the coupling portions 24 and the stoppers 25 are installed at intervals. Slots 26 are uniformly sandwiched between the stoppers 25 and the coupling pipes 21, and first and second groove portions 27 and 28 are uniformly molded in the stoppers and the coupling pipes 21 and the first groove portions 27 and The second groove 28 is located in the center of the slot 26. A reinforcing rib 29 is molded between the first groove portion 27 and the second groove portion 28, and a gate-shaped protection rod 77 is inserted. The grooved cylindrical tube 71 is drilled in the passage 22 and is limited in position by a lantern ring 73 and is tightly positioned in the passage 22. The coupling method between the grooved cylindrical tube 70 and the lantern ring is a conventional technique, and is not an emphasis of the present invention. By being coupled to the grooved cylindrical tube 71, a coupling structure that is perpendicular to the ground is provided.

The coupling member 30 has a front surface 31 and a rear surface 32 opposite to the front surface 31. The rear surface 32 is an arc surface and has two side surfaces. An engaging portion 33 is formed downward from the bottom end of the first member, and the engaging portion 33 is an elastic engaging structure formed in a convex shape on the bottom end of the coupling member 30. Convex portions 34 are respectively formed on the two side surfaces, and the coupling member 30 is formed in the coupling portion 24 by the engagement portion 33 and combined with the base 20, and abuts against the coupling tube 21 by the rear surface 32. Is done. The two protrusions 34 are respectively provided in the adjacent slots 26, and a through hole 35 is formed between the front surface 31 and the rear surface 32 of the coupling member 30. A rib 38 is provided or molded below the through hole 35 on the surface 31 of the part. A storage portion 36 is molded on the rear surface 32 of the through hole 35, a bolt 74 is stored in the storage portion 36, and the tube member 72 is screwed to the coupling member by the bolt 74. In the present embodiment, the plug portion 75 is first embedded in the pipe member 72, the bolt 74 is a hexagon socket bolt, and a plurality of self-tapping screws 37 are provided below the through hole 35 of the coupling member 30. The rails, drawers, baskets and the like are screwed by the self-tapping screws 37.

The above is description of the main members and form which concern on embodiment of this invention. With respect to the method of use and effects of the embodiment, as shown in FIGS. 1 to 3, 4 and 5, in actual use of the present invention, first, the two ends of the tube member 72 of a square tube or a circular tube are used for coupling. The plug portion 75 is first embedded in the opening at the two ends of the pipe member 72, and the bolt 74 is drilled in the coupling member 30 through the storage portion 36 and the through hole 35 in order. One end of the bolt 74 is provided in the storage portion 36, and the other end protrudes from the through hole 35 and is screwed into the plug portion 75 of the pipe member 72. The user installs the two ends of the pipe member 72 on the two coupling members 30, respectively, and then sets the engaging portions 33 of the two coupling members 30 to one of the two different bases 20. Each of the projections 34 of the coupling member 30 is installed in the adjacent slot 26. The coupling member 30 is coupled to the pipe member 72 and has a coupling structure parallel to the ground. The coupling member 30 is coupled to the grooved cylindrical pipe 71 in combination with the coupling member 30, and the rack frame is installed according to the present invention. .

In addition, after the slot 26 of the base 20 of the present invention is coupled to the convex portion 34 of the coupling member 30, a part of the slot 26 becomes a gap for inserting two ends of the gate-shaped protection rod 77. The first groove part 27 and the second groove part 28 are further molded, and the gap-shaped protection rod 77 is inserted by expanding the gap. In the drawing, the gate-type protection rod 77 is inserted so that two ends thereof straddle two adjacent bases 20 to prevent the article placed on the plate member 76 from dropping. In addition, each self-tapping screw 37 fixes a slide, a drawer, a basket or the like to the bottom of the base 20 according to the user's demand, thereby enhancing the practicality of the present invention.

Further, a plurality of coupling members 30 are installed on the base 20 of the present invention, and each coupling member 30 is evenly coupled to the pipe member 72. As a result, the rack of the present invention is inserted according to the user's demand, is extended freely in the plane direction, and the combination can be changed according to preference when installed and used (see FIG. 7). .

In addition, a rib 38 is provided or molded below the through hole 35 in the front surface 31 of the coupling member 30. As a result, the tube member 72 that is in contact with the tube member 72 and coupled to the coupling member 30 rotates so as not to impair the aesthetic appearance of the rack.
