Description

Technical Field

[0001] The utility model relates to the technical field of packaging box equipment, in particular to a quick-detachable steel composite packaging box. Background Art

[0002] Steel composite packaging boxes are mainly made of composite steel materials and are generally used for packaging and transportation of mechanical parts. Because they have the characteristics of two different types of steel, they have the corrosion resistance of stainless steel and the advantages of low price and good rigidity of ordinary steel. Composite steel is designed to protect ordinary steel plates from rust. Electroplating, bonding and spraying methods can be used to cover the surface of the steel plate with a layer of protective "coat" to form a composite steel plate.

[0003] Currently, traditional steel composite packaging boxes generally use bolt connections or hinged connections to swing the packaging box baffle to open the packaging box. This requires tedious disassembly when loading goods before direct loading with automated equipment. Therefore, a quick-release steel composite packaging box is proposed to change the current situation. Utility Model Content

[0004] In response to the above problems, the present invention provides a quick-disassembly steel composite packaging box. When disassembly is required, the ring pin or the ball head pin only needs to be directly pulled out to separate it from the penetrating connecting nesting tube and the fixed column rotating shaft tube, thereby achieving the effect of quick disassembly of the first and second opening and closing doors or the left and right box doors.

[0005] To achieve the above-mentioned object, the present invention is implemented through the following technical solutions: a quick-release steel composite packaging box, comprising a packaging box, a box bottom plate provided inside the packaging box, a plurality of forklift slots installed on the lower surface of the box body plate, a plurality of box support columns fixed to the four corners above the box bottom plate, and outer protective plywood fixed to the outer sides of the box bottom plate and the box support columns; a column body provided inside the plurality of box support columns, a first opening and closing door installed on one side of the column body, a second opening and closing door installed on the other side of the column body, a plurality of left and right box doors installed between the columns, a ball latch inserted into the column body, a ring latch inserted into the column body, and a plurality of fixed column rotating shaft cylinders installed on the surface of the column body. The ring latch or ball latch provided on the column body is used for hinged cooperation or restriction of the door body, so that when disassembling, only the ring latch or ball latch needs to be pulled outward to form a quick disassembly of the left and right box doors or the first and second opening and closing doors installed between them.

[0006] Furthermore, the first opening and closing door is provided with a door panel, a connecting nesting tube being fixed to one side wall of the door panel, and a directional closing strip being mounted on one side of the door panel. The reverse closing strip has a plurality of threaded holes, each of which is connected to a fixing bolt. The reverse closing strip is primarily used to close the first and second opening and closing doors, allowing them to quickly close and form a horizontal, unified plane, forming a connected door. The fixing bolt is primarily used to secure the two doors.

[0007] Furthermore, the door panel is mounted between the column-fixing shaft cylinder via the connecting nesting cylinder, and the ring latches extend through both the connecting nesting cylinder and the column-fixing shaft cylinder. The door panel can swing through an angle of less than or equal to 90° via the connecting nesting cylinder and the ring latches. The door panel swings open and close primarily through the cooperation of the ring latches, with a maximum opening and closing angle of 90°, facilitating automated mechanical transport of items within the packaging box.

[0008] Furthermore, the second opening and closing door is identical to the first opening and closing door except for the opposite mounting positions of the fixing bolt and the reverse closing strip. The ball latches extend through the left and right doors and the fixed column pivot cylinder. Both ends of the left and right doors are penetrated by the ball latches, and removal of one side allows for a swing angle of less than or equal to 90°. Ball latches extend through both sides of the left and right doors, allowing them to be installed on both sides of the column. To close the columns, the ball latches at both ends must be pulled out for connection. To open and close, only the ball latch at one end needs to be pulled out to achieve a maximum opening and closing angle of 90°.

[0009] Beneficial effects

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The utility model fixes the first and second opening and closing doors by connecting the nested cylinder with the cooperation of the ring latch and the fixed column shaft cylinder, so that if there is no need for plugging during use, the fixing bolt can be removed to allow the first and second opening and closing doors to swing less than or equal to 90 degrees, thereby facilitating the installation of goods and automation. When disassembly is required, the ring latch or the ball head latch can be directly pulled out to complete the effect of quick disassembly of the first and second opening and closing doors or the left and right box doors.
