Demountable installation structure and shelving

Abstract

A detachable mounting structure includes a first object and a second object. The first object has a first mating structure, which includes an insertion port and a tongue, the tongue being located within the insertion port. The second object has a second mating structure, which includes a hook. The hook is a curved piece connected to the second object at both ends and is fitted onto the tongue. The portion of the second object with the second mating structure overlaps with the portion of the first object with the first mating structure. This detachable mounting structure can be used in shelving and can be installed without tools, achieving rapid assembly.

5. The shelf as described in claim 4, wherein each of the second docking structures includes a fastener through-hole formed on the first crossbar or the second crossbar and located directly above the hook, wherein when each hook is engaged with each latch, the fastener through-hole faces the entrance / exit area.

6. The shelving as described in claim 5, wherein a bolt and nut assembly is provided at each of the fastener insertion openings and at each of the corresponding entrance / exit areas.

7. A shelving unit comprising four uprights, four first horizontal bars, and four second horizontal bars, wherein: The columns are rods extending vertically and arranged in a rectangular quadrant. Each column includes a first long plate and a second long plate connected together. The first long plate of any two adjacent columns is relative to the second long plate of the other column. A second mating structure is formed on the upper and lower sides of each first long plate and a second mating structure is formed on the upper and lower sides of each second long plate. The second mating structures have the same construction. Each second mating structure includes a hook, which is a bent plate connected to the column at both ends. An insertion hole is formed in the hook. Each first crossbar spans between the upper side of each first long plate and the upper side of each second long plate, and the first crossbars are arranged in a rectangular shape on the upper side of the columns; each of the two ends of each first crossbar forms a first mating structure, and one of the two first mating structures of each first crossbar is detachably connected to the second mating structure on the upper side of the corresponding first long plate, and the other of the two first mating structures is detachably connected to the second mating structure on the upper side of the second long plate; each second crossbar spans between the lower side of each first long plate and the lower side of each second long plate, and the second crossbars are arranged in a rectangular shape on the lower side of the columns; each of the two ends of each second crossbar forms a first mating structure, and one of the two first mating structures of each second crossbar is detachably connected to the second mating structure on the lower side of the corresponding first long plate, and the other of the two first mating structures is detachably connected to the second mating structure on the lower side of the second long plate; These first docking structures have the same construction.
