The present invention relates to a collapsible storage box which is expanded and retracted quickly and easily.
A conventional collapsible storage box contains a base, four peripheral plates arranged on the base, a cap covered on an opening defined by the base and the four peripheral plates. However, it will occupy a large space as retracting the conventional collapsible storage box.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary aspect of the present invention is to provide a collapsible storage box which is expanded and retracted quickly and easily.
Another aspect of the present invention is to provide a collapsible storage box which is retracted in a small size.
To obtain the above aspects, a collapsible storage box provided by the present invention contains: a bottom plate, a first long plate, a second long plate, and two foldable short plates.
Each of the two foldable short plates includes a first connection sheet and a second connection sheet.
A front end of the bottom plate retains with multiple first L-shaped hooks on a bottom of the first long plate, multiple first rotary shafts on a rear end of the bottom plate rotatably connect with multiple first retainers on a bottom of the second long plate respectively, a first side of the bottom plate retains with a first flexible hook on a bottom of the first connection sheet of each foldable short plate, and a second side of the bottom plate retains with a second flexible hook on a bottom of the second connection sheet of each foldable short plate.
The bottom plate includes multiple locking recesses defined on the front end thereof, the multiple first rotary shafts arranged on the rear end of the bottom plate, multiple first notches arranged among the multiple first rotary shafts respectively, and multiple first cutouts formed on the first side and the second sides of the bottom plate.
The first long plate includes multiple second retainers arranged on a first side and a second side thereof individually, multiple second cutouts defined among the multiple second retainers respectively, the multiple first L-shaped hooks formed on the bottom of the first long plate, and multiple second notches defined among the multiple first L-shaped hooks individually.
The second long plate includes two ribs arranged on a first side and a second side thereof individually, multiple third retainers arranged on the two ribs respectively, multiple L-shaped recesses defined among the multiple third retainers individually, and the multiple first retainers formed on the bottom of the second long plate.
Each foldable short plate includes the first connection sheet and the second connection sheet, and the two foldable short plates correspond to each other.
The first connection sheet includes multiple second rotary shafts arranged on a first side thereof, multiple second L-shaped hooks formed among the multiple second rotary shafts respectively, multiple third rotary shafts arranged on a second side of the first connection sheet, multiple third notches defined among the multiple third rotary shafts individually, two fourth notches formed on the bottom of the first connection sheet, the first flexible hook defined between the two fourth notches, a first coupling seat formed on a corner of a top of the first connection sheet adjacent to the second connection sheet, a first indentation defined on a bottom of the first coupling seat, and a first shoulder formed on a front end of the first indentation, wherein the first coupling seat has a U-shaped abutting piece, a slip defined inside the U-shaped abutting piece, an engaging dent formed in the slip.
The second connection sheet includes multiple fourth retainers arranged on a first side thereof adjacent to the second side of the first connection sheet, multiple third L-shaped hooks defined among the multiple fourth retainers individually, multiple fourth rotary shafts arranged on a second side of the second connection sheet, multiple fourth L-shaped hooks formed among the multiple fourth rotary shafts respectively, two fifth notches formed on the bottom of the second connection sheet, the second flexible hook defined between the two fifth notches, a second coupling seat formed on a corner of a top of the second connection sheet adjacent to the first connection sheet, a second indentation defined on a bottom of the second coupling seat, and a second shoulder formed on a front end of the second indentation.
