The butt-joining and engaging structure has a seat body with a first connecting portion and a through hole, a stop part extends from an inner wall of the through hole toward the center of the through hole, a connecting member has a pair of ends defining a plug-in portion and a second connecting portion, and a position limiting part protrudes from the abutment surface of the connecting member. The first connecting portion is adapted to be affixed to one of the pair of columns. The second connecting portion is adapted to be secured to an end of the other column.

A manually assemblable/disassemblable rack mount for a load comprising: (a) a frame having first and second parallel spaced uprights arranged in a pair; each upright comprising a side projection having notches distributed along said side projection; (b) at least one crossbar member having first and second terminals; said at least one crossbar member releasably securable between said first and second parallel spaced uprights. The rack mount comprises terminal adapters connectable to said first and second terminals. The rack mount comprises anchoring plug members insertable into said notches. Each terminal adapter has a claw insertable into a bore within said anchoring plug members. At least one crossbar with said terminal adapters connected to said first and second terminals of said at least one crossbar is releasably mountable in a bridge position between said first and second parallel spaced uprights.

A frame hooking and connecting structure includes a column, each side of which is formed with a first through hole, and a parallel second through hole. A first support rod is provided to hook the column. The two ends of the first support rod are extended with a fastening part, and the free end of the fastening part is connected with a first hook, which is hooked and positioned to the bottom edge of the first through hole, and the fastening part is attached to a corresponding end surface of the column. A second support rod is provided to hook the column. The ends of the second support rod are respectively extended with a second hook, and the free end of the second hook penetrates through the hollow portion and the second through hole into the column, and is locked to the bottom edge of the second through hole.

A modular frame with a U-shaped hook member includes multiple upright columns each having at least two faces of each of the multiple upright columns have multiple couples of first through hole and second through hole defined therein. Multiple horizontal columns are respectively connected to a corresponding one of the at least two faces of a corresponding one of the multiple upright columns. Two connecting blocks respectively mounted into a corresponding one of two opposite ends of the tube. Two U-shaped hook members are respectively mounted into a corresponding one of the two connecting blocks. Each U-shaped hook member includes a first hook and a second hook extending therefrom and respectively engaged to a lower portion of a corresponding on of the first through holes and the second through holes.

An aluminum alloy cabinet board is revealed. A plurality of cabinet boards can be assembled into a cabinet assembly. The cabinet board includes a central plate, two lateral base plates and a plurality of cover plates. A hollow part is penetrating through the lateral base plate and a reinforcement tube is mounted into the hollow part. A plurality of pressing bolts is passed through the central plate and the two lateral base plates for fastening and positioning firmly. Thereby the structural strength of the whole cabinet board is improved. The design of the cabinet board also prevents insects from getting therein so that the cabinet board is insect resistant.

A modular shelving system and method, the system comprising mounting brackets, a bottom shelving rod, a top shelving rod and a support shelving rod, the mounting brackets are attach to a vertical surface to support at least one bottom shelving rod and at least one top shelving rod in a spaced-apart and parallel orientation to each other shelving rod; the bottom shelving rod further defining tandem spaced-apart open-ended cups; the top shelving rod further defining spaced apart tandem top rod apertures that penetrate through the top shelving rod; at least one support shelving rod having a circumference that allows passage of one support shelving rod through a respective top rod aperture to allow a support shelving rod to removably connected to a respective open-end cup to locate the support shelving rod between horizontal and vertical positions.

A load module for inserting into a tube of a three-dimensional supporting tube structure of a furniture system comprises an elongate housing. Arranged on an outer side of the housing are two contact elements having different polarities for electrically contacting the load module. The contact elements arranged such that, with the load module in inserted states, they contact two contact surfaces of different polarity, which are arranged in the interior of the tube, in a radial direction. Housing has a central region in a longitudinal direction with at least one projecting element and outer regions in the longitudinal direction, the load module can be inserted into a tube, which is provided with an elongate opening, of the tube structure such that the at least one projecting element interacts with an edge of the opening, and the outer regions bear against an inner lateral surface of the tube in regions adjoining the opening. A first of the contact elements is arranged in a first circumferential position in one of the outer regions.

Disclosed is a frame with connecting and positioning structure. The frame has a plurality of cross bars and vertical bars which are correspondingly connected through the connecting and positioning structure. The connecting and positioning structure includes: a fixing seat fixed to the end of the cross bar; a fitting groove on the fixing seat; one end of the fitting groove is extended toward the bottom edge of the cross bar to form an opening end; an embedded block is provided for embedding in the retaining groove of the vertical bar; a plug-in column is connected with the embedded block; a fitting convex portion is connected to the other end of the plug-in column, and the fitting convex portion and the plug-in column are correspondingly inserted into the fitting groove; and a fixing member penetrates through the embedded block, the fitting convex portion, and the plug-in column to connect them together.
