A cover plate, a corner seat sleeved at the corners of the two side plates, and a fastening piece used for the snap connection between the cover plate and the side plates, when the four side plates are overlapped with each other at an appropriate angle, the cover is closed In the shape of a profile, and in the opening at the top of each side panel, a cover plate is assembled and assembled so that the box body becomes a closed structural shape, and the above components are used to complete the extremely simple assembly action. Engaging assembly between the bottom plate, the side plates and the cover plate, and more preferably formed coupling retaining solid. Sovereignty item 1. A group connection structure of a closed metal box, whose box body is a box structure constructed by welding corner materials and a bracket; and is characterized in that: it includes: four side plates, and The corner material is pre-welded into a frame with a specific contour, and a bracket with an excessive thickness is welded on the angle material to form a side panel structure with considerable strength. The side panel is provided with the aforementioned horizontal panel and the aforementioned vertical panel. The angular material-like structure of the body is such that the plate edge of the side plate has a considerable thickness from the horizontal plate body, and the vertical plate body is joined by welding of other supports, and the side plate contacted by the both side plates has mutual ability. A chimera-shaped cross-section is formed on the abutting side of the cross-section, and a card and an insert hole are formed to engage with each other, and the side plates can be firmly joined; and a cover plate whose edge of the cover plate is bent downward is provided. The cover can be covered with the joints on the outside of the vertical sheet body of each side plate, and the cover plate and the side plates are covered; and the card connector is fixed on the bottom plate for lap joints with the side plates. Flatly attached to the bottom surface of the bottom plate and bent on the bottom surface to form an edge with the bottom plate In the vertical plate of the row, the bottom edge of the vertical plate is bent to form a positioning seat corresponding to the outside of the box body. The positioning seat has a protrusion parallel to the vertical plate at the outer side corresponding to the box. And a slot is arranged at the protrusion; and the clamping block is fixed at the edge of the plate where the side plates overlap with the base plate, and is an L-shaped cross-section structure with a vertical edge and a flat bottom surface so that the bottom surface is flat; Corresponding to the vertical edge and the board edge of the side board, and the side board corresponding to the inner side of the box, and on the main body of the vertical edge, there is provided a protrusion that can be engaged with the slot of the card seat. The corners; the corner seats are provided at the corners of the two side plates, and have a seat plate matching the angles of the two side plates, and are formed with downward bending at the included angles of the seat plates corresponding to the two side plates. The frame clamping portion is clamped on the outside of the vertical plate body of the side plate bracket by the frame clamping portion, and the corner bracket is further bent upwards from the bottom of the frame clamping portion by a clamping portion to be clamped by the clamping portion and the frame clamping portion. The gap between the gaps serves as a space for inserting the engaging portion of the cover plate, and the lug and the end hole that can be inserted into each other at the top of the corner plate and the top plate of the side plate. In addition, at the horizontal plate body of the seat plate of the corner seat and the top surface of the side plate, inserting and inserting seams which can be inserted into each other are respectively provided; the fasteners are fastened between the cover plate and the side plates through the fasteners. The fastener is a clip-shaped structure with a U-shaped cross-section, and has an inter-clamped inner clip piece and an outer clip piece. The end of the outer clip piece is bent toward the inner clip piece. A press abutment portion is extended; four side plates are overlapped with each other at appropriate angles to form a closed-like shape, and at the opening of the top of each side plate, a cover is assembled with the cover to make the box body into a closed structural body.
