Description

Technical Field

[0001] The utility model relates to the technical field of corrugated box covers, in particular to a corrugated box cover. Background Art

[0002] A carton is a three-dimensional shape. It is a polyhedron formed by the movement, stacking, folding and surrounding of several surfaces. The surfaces in the three-dimensional structure play the role of dividing space in space. Cutting, rotating and folding the surfaces in different parts will result in different emotional expressions. The composition relationship of the display surface of the carton should pay attention to the connection between the display surface, side, top and bottom, as well as the setting of packaging information elements. Corrugated box is a kind of carton. Corrugated box is also called corrugated box or paper box, sometimes just called carton. It is a box made of corrugated paper or pasted together, often used for packaging items for easy transportation.

[0003] During transportation, existing corrugated boxes will deform or even crack after being handled multiple times, which can easily affect the use of the entire carton. In addition, collisions may occur during transportation, causing damage to the internal products. At the same time, the cover on the top of the corrugated box is prone to shaking during transportation, causing the cover to fall off, resulting in the objects inside the box being directly exposed to the outside, which can easily affect the safety of the storage of items. Therefore, this application proposes another technical solution to solve this problem. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 A corrugated box cover in this embodiment includes a corrugated box body 1, and an adjustable switch cover mechanism is arranged on the outer side of the corrugated box body 1.

[0023] In this embodiment, the regulating switch cover mechanism includes a box cover body 2 movably connected to the top of the corrugated box body 1, fixed shafts 3 are fixedly installed on the left and right sides of the corrugated box body 1, and a return spring 4 is movably connected to the outer side of the fixed shaft 3, and a movable plate 5 fixedly connected to the return spring 4 is slidably connected to the outer side of the fixed shaft 3.

[0024] Among them, a movable groove adapted to the fixed shaft 3 is opened inside the movable plate 5, and the movable plate 5 is slidably connected to the fixed shaft 3 through the movable groove, which helps the movable plate 5 to slide on the outside of the fixed shaft 3. The left and right sides of the corrugated box body 1 are fixedly installed with sliding rods 6 located directly below the fixed shaft 3.

[0025] In this embodiment, the outer side of the slide rod 6 is slidably connected to a slide block 7 fixedly connected to the movable plate 5, and a limiting groove is provided inside the slide block 7. The slide block 7 is slidably connected to the slide rod 6 through the limiting groove, which helps the slide block 7 to slide on the slide rod 6. A handle frame 8 is fixedly installed on one side of the movable plate 5. A limiting pin 9 plugged into the corrugated box body 1 and the box cover body 2 is fixedly installed on one side of the movable plate 5. A through groove is provided inside the box cover body 2, and the limit pin 9 is movably connected to the box cover body 2 through the through groove, which helps the limit pin 9 to move inside the box cover body 2.

[0026] Among them, slots are opened on the left and right sides of the corrugated box body 1, and the limit pin 9 is inserted into the corrugated box body 1 through the slots, which is convenient for fixing and disassembling the box cover body 2 and the corrugated box body 1. Buffer components are arranged inside the corrugated box body 1. There are four buffer components, and the buffer components are located in the four corners inside the corrugated box body 1, which is convenient for effective buffering and shock absorption.

[0027] In this embodiment, four fixing plates 10 are fixedly installed on the inner bottom wall of the corrugated box body 1, a buffer spring 11 is fixedly installed on one side of the fixing plate 10, a supporting plate 12 is fixedly installed on the side of the buffer spring 11 away from the fixing plate 10, a hinge rod 13 is hinged between the fixing plate 10 and the supporting plate 12, and a buffer pad 14 is fixedly connected to the inner wall of the corrugated box body 1 and one side of the supporting plate 12.

[0028] It should be noted that the corrugated box cover is used to place items into the interior of the corrugated box body 1 through the adjustable switch mechanism. When the device shakes during transportation, the buffer pad 14 is squeezed by the items, thereby squeezing the buffer spring 11, and the hinged rod 13 is hinged and retracted. The buffer pad 14 and the buffer spring 11 perform buffering, which helps to improve the stability and safety of the device. Pulling the handle frame 8, under the action of the movable plate 5, the return spring 4 and the slider 7, can drive the limit pin 9 to move to fix and seal the box cover body 2 and the corrugated box body 1 or to disassemble the box cover body 2, which greatly improves the flexibility and practicality of the device.

[0029] The working principle of the above embodiment is:

[0030] When the corrugated box cover is used, the box cover body 2 is first opened, and then the items to be stored can be placed inside the corrugated box body 1, and the items are placed on the top of the buffer pad 14. During the transportation process of the corrugated box body 1, the items are shaken on the top of the buffer pad 14, and the buffer pad 14 is squeezed by the items, thereby squeezing the buffer spring 11, and the hinge rod 13 is hinged and retracted to support the bearing plate 12, so that the buffer spring 11 can be used to buffer the buffer pad 14, which helps to improve the stability and safety of the device. When the corrugated box body 1 needs to be closed, the handle frame 8 is first pulled, and the handle frame 8 drives the movable plate 5 to slide on the outside of the fixed shaft 3, and the movable plate 5 The movement drives the limit pin 9 to move, so that the limit pin 9 contracts, and the movable plate 5 compresses the return spring 4. Then the box cover body 2 can be covered on the top of the corrugated box body 1, and the through groove of the box cover body 2 is aligned with the limit pin 9. Then the handle frame 8 can be slowly loosened, and the return spring 4 starts to reset automatically, and drives the movable plate 5 and the limit pin 9 to reset and move. At the same time, the slider 7 limits the movable plate 5 until the limit pin 9 is inserted into the inside of the corrugated box body 1 and the box cover body 2, so as to fix and seal the box cover body 2 and the corrugated box body 1, or pull the handle frame 8 to separate the limit pin 9 from the inside of the corrugated box body 1, so as to disassemble it, which greatly improves the flexibility of the corrugated box cover.
