Description

Technical Field

[0001] This utility model belongs to the field of corrugated cardboard box technology, specifically relating to a corrugated cardboard box with reinforced corners. Background Technology

[0002] Corrugated paper is a material made from cardboard through a corrugated board machine, commonly used in packaging, protection, and transportation. It is lightweight, sturdy, pressure-resistant, heat-insulating, and shock-absorbing, and is widely used in various packaging boxes, cartons, packing mats, and insulation pads.

[0003] Existing corrugated cardboard boxes are made by folding. During the folding process, the wavy structure inside the corrugated cardboard at the corners is damaged, resulting in poor strength at the corners and even overall deformation. When the corrugated cardboard box is severely deformed, it can damage the products inside. Therefore, we provide a corrugated cardboard box with reinforced corners. Utility Model Content

[0004] The purpose of this invention is to provide a corrugated cardboard box with reinforced corners to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrugated cardboard box with corner reinforcement, comprising a corrugated cardboard box body, a rectangular sleeve post, and fastening bolts. Adjusting rods are movably connected to both sides of the inner cavity of the rectangular sleeve post. A first reinforcing plate is fixedly connected to one end of the adjusting rod. A connecting post is fixedly connected to the surface of the adjusting rod. A second reinforcing plate is fixedly connected to one end of the connecting post. A set of threaded grooves is provided on the adjusting rod. The threaded grooves and the rectangular sleeve post are fixedly connected by fastening bolts.

[0006] Using the above scheme, the first reinforcing plate and the connecting column are moved to one side by the adjusting rod, and the second reinforcing plate is moved to one side by the connecting column until the first and second reinforcing plates are in contact with the internal corner of the corrugated cardboard box body and the movement stops. By changing the position of the first and second reinforcing plates, the device can be applied to corrugated cardboard boxes of different sizes, which greatly improves the practicality of the device.

[0007] In a preferred embodiment of a corrugated cardboard box with corner reinforcement, a nut is threaded onto the bottom of the fastening bolt surface, and the top of the nut fits against the bottom of the rectangular sleeve.

[0008] By adopting the above solution, the interaction between the threads of the nut and the fastening bolt is utilized to prevent them from loosening or separating under stress, thus greatly improving the stability of the fastening bolt during use.

[0009] In a preferred embodiment of a corrugated cardboard box with corner reinforcement, the top and bottom sides of the rectangular sleeve are provided with through holes for fastening bolts to pass through, and the diameter of the through holes is larger than the diameter of the fastening bolts.

[0010] By adopting the above scheme, since the diameter of the through hole is larger than the diameter of the fastening bolt, the fastening bolt can quickly pass through the inner cavity of the rectangular sleeve, thereby achieving the limiting operation.

[0011] In a preferred embodiment of a corrugated cardboard box with corner reinforcement, the number of threaded grooves is seven, and the distance between every two threaded grooves is ten centimeters.

[0012] Using the above method, since the distance between every two threaded grooves is ten centimeters, precise adjustment can be achieved without the need for external measuring tools during the adjustment process.

[0013] In a preferred embodiment of a corrugated cardboard box with corner reinforcement, a sliding groove is provided on one side of the top and bottom of the inner cavity of the rectangular sleeve column, and a slider is fixedly connected to the top and bottom of one side of the adjusting rod, with one end of the slider slidably connected to the inner wall of the sliding groove.

[0014] By adopting the above scheme, the movement distance of the adjusting rod is limited by the setting of the sliding groove and the cooperation of the slider, so as to prevent the adjusting rod from completely disengaging from the inner cavity of the rectangular sleeve.

[0015] In a preferred embodiment of a corrugated cardboard box with corner reinforcement, a set of two reinforcing ribs are fixedly connected to the inner cavity of the rectangular sleeve column.

[0016] By adopting the above solution and adding reinforcing ribs, the strength and rigidity of the rectangular sleeve column are increased during use, which greatly improves the service life of the rectangular sleeve column.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses an adjusting rod to move the first reinforcing plate and the connecting column to one side, and the connecting column to move the second reinforcing plate to one side until the first and second reinforcing plates are in contact with the internal corner of the corrugated cardboard box body and the movement stops. By changing the position of the first and second reinforcing plates, the device can be applied to corrugated cardboard boxes of different sizes, which greatly improves the practicality of the device.

[0019] 2. In this utility model, the fastening bolt is turned in from the top of the rectangular sleeve column and passes through the inner wall of the threaded groove until it extends out from the bottom of the rectangular sleeve column and stops moving. The fastening bolt fixes the position of the adjusting rod and prevents the adjusting rod from sliding during use, thereby reducing the reinforcement effect. Attached Figure Description

[0024] Please see Figure 1-3 A corrugated cardboard box reinforced with folded corners includes a corrugated cardboard box body 1, rectangular sleeve posts 2, and fastening bolts 9, see Figure 3 As shown, a nut 10 is threadedly connected to the bottom of the fastening bolt 9. The top of the nut 10 fits against the bottom of the rectangular sleeve 2. The nut 10, through its interaction with the threads of the fastening bolt 9, prevents loosening or separation under stress, greatly improving the stability of the fastening bolt 9 during use. Adjusting rods 4 are movably connected to both sides of the inner cavity of the rectangular sleeve 2. A first reinforcing plate 5 is fixedly connected to one end of the adjusting rod 4, and a connecting post 6 is fixedly connected to the surface of the adjusting rod 4. A second reinforcing plate 7 is fixedly connected to one end of the connecting post 6. A set of threaded grooves 8 are provided on the adjusting rod 4. Figure 2 As shown, there are seven threaded grooves 8, and the distance between every two threaded grooves 8 is ten centimeters. Because the distance between every two threaded grooves 8 is ten centimeters, precise adjustment can be achieved without the need for external measuring tools during the adjustment process. The threaded grooves 8 and the rectangular sleeve column 2 are fixedly connected by fastening bolts 9. The first reinforcing plate 5 and the connecting column 6 are moved to one side by the adjusting rod 4, and the second reinforcing plate 7 is moved to one side by the connecting column 6 until the first reinforcing plate 5 and the second reinforcing plate 7 are in contact with the internal fold corner of the corrugated cardboard box body 1 and the movement stops. By changing the usage position of the first reinforcing plate 5 and the second reinforcing plate 7, the device can be applied to corrugated cardboard box bodies 1 of different sizes, which greatly improves the practicality of the device.

[0025] See Figure 3 As shown, the rectangular sleeve 2 has through holes on both the top and bottom sides for the fastening bolts 9 to pass through. The diameter of the through holes is larger than the diameter of the fastening bolts 9. Because the diameter of the through holes is larger than the diameter of the fastening bolts 9, the fastening bolts 9 can quickly pass through the inner cavity of the rectangular sleeve 2, thereby achieving the limiting operation. Figure 3As shown, a sliding groove 11 is provided on one side of the top and bottom of the inner cavity of the rectangular sleeve 2. A slider 12 is fixedly connected to the top and bottom of one side of the adjusting rod 4. One end of the slider 12 is slidably connected to the inner wall of the sliding groove 11. Through the setting of the sliding groove 11, with the cooperation of the slider 12, the movement distance of the adjusting rod 4 is limited, preventing the adjusting rod 4 from completely detaching from the inner cavity of the rectangular sleeve 2. Figure 3 As shown, a set of reinforcing ribs 3 are fixedly connected to the inner cavity of the rectangular sleeve 2. There are two reinforcing ribs 3. By setting the reinforcing ribs 3, the strength and rigidity of the rectangular sleeve 2 are increased during use, which greatly improves the service life of the rectangular sleeve 2.

[0026] In use, first place the rectangular sleeve 2 at the bottom of the inner cavity of the corrugated cardboard box body 1, so that the bottom of the first reinforcing plate 5 is in contact with the bottom of the inner cavity of the corrugated cardboard box body 1, and the rectangular sleeve 2 is suspended in the air. After placement, if the size of the corrugated cardboard box body 1 is too large, hold the adjusting rod 4 and pull it to one side. The adjusting rod 4 will move the first reinforcing plate 5 and the connecting post 6 to one side, and the connecting post 6 will move the second reinforcing plate 7 to one side, until the first reinforcing plate 5 and the second reinforcing plate 7 are in contact with the inner corner of the corrugated cardboard box body 1, and the movement will stop. The position of the first reinforcing plate 5 and the second reinforcing plate 7 can be changed. This allows the device to be applied to corrugated cardboard box bodies 1 of different sizes, greatly improving the device's practicality. Then, the fastening bolt 9 is turned in from the top of the rectangular sleeve 2 and passes through the inner wall of the threaded groove 8 until it extends out from the bottom of the rectangular sleeve 2 and stops moving. The fastening bolt 9 fixes the position of the adjusting rod 4 to prevent the adjusting rod 4 from slipping during use, thereby reducing the reinforcement effect. Finally, the nut 10 is screwed into the surface of the fastening bolt 9 from the bottom until the top of the nut 10 fits against the bottom of the rectangular sleeve 2 and stops moving, further improving the stability of the fastening bolt 9 during use.
