[0014] Beneficial effects

[0015] This invention provides a staggered adhesive paper corner box to increase the compressive strength of products. Compared with the prior art, it has the following advantages:

[0016] 1. This staggered adhesive paper corner box, designed to increase product load-bearing capacity, works by first transferring the weight of goods to the bottom of the box body when it carries cargo. At this point, the bottom load-bearing components come into play. The first cardboard, directly bearing the weight of the goods, distributes the pressure onto the transverse corrugated cardboard. The corrugated structure itself provides some compressive strength, and an internal set of transverse support rods further enhances the transverse support strength, allowing the transverse corrugated cardboard to better withstand the transverse pressure from the goods. Next, the pressure is transferred through the transverse corrugated cardboard to the vertical corrugated cardboard. The corrugated structure of the vertical corrugated cardboard, in conjunction with the vertical support rods, effectively withstands the vertical pressure, distributing it evenly to the second cardboard. Finally, the second cardboard transfers the pressure to the ground, thus achieving effective load-bearing and pressure distribution, improving the load-bearing capacity of the box bottom. This reduces the problem of easy deformation and damage to the bottom of traditional paper corner boxes, prevents goods from falling out of the box, and improves the safety of cargo transportation.

[0017] 2. This offset-bonded cardboard corner box, designed to increase the product's pressure resistance, allows for easy closure of the lid. To close the lid, rotate it downwards, causing the snap-fit ​​shell to gradually approach the mounting shell. When the snap-fit ​​shell contacts the beveled edge block, the beveled edge block is compressed by the snap-fit ​​shell, pushing the sliding plate within the mounting shell and compressing the spring. After the snap-fit ​​shell passes the beveled edge block, the spring force causes the sliding plate to return to its original position, and the beveled edge block engages with the snap-fit ​​shell, securing the lid to the carton body. To open the lid, press the pressing block, causing the sliding plate to slide within the mounting shell, disengaging the beveled edge block and allowing the lid to be easily opened.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides two technical solutions:

[0026] Figures 1-5 The first embodiment is shown: a staggered adhesive paper corner box for increasing the compressive strength of the product, including a carton body 1, a box cover 2 hinged to the top of the carton body 1, a bottom pressure-bearing component 3 provided at the bottom of the carton body 1, and a snap-fit ​​component 6 provided on the outer wall of the carton body 1.

[0027] The bottom pressure-bearing component 3 includes a first cardboard 31 and a second cardboard 37. A transverse corrugated cardboard 33 is glued to the bottom end of the first cardboard 31. A set of transverse support rods 34 are fixedly installed on the inner wall of the transverse corrugated cardboard 33. A vertical corrugated cardboard 35 is glued to the bottom end of the transverse corrugated cardboard 33. A set of vertical support rods 36 are fixedly installed on the inner wall of the vertical corrugated cardboard 35. The bottom end of the vertical corrugated cardboard 35 is fixedly connected to the second cardboard 37. The middle of the corrugated cardboard is composed of multiple pairs of inclined plates, which can improve the compressive strength. Support rods are inserted between the inclined plates, which can further improve the compressive strength.

[0028] The snap-fit ​​assembly 6 includes a mounting shell 61 and a snap-fit ​​shell 68. A set of springs 62 is provided on the inner wall of the mounting shell 61. A sliding plate 64 is fixedly connected to one end of the set of springs 62. A beveled snap-fit ​​block 67 is provided at the top of the sliding plate 64.

[0029] A mounting frame 32 is fixedly installed on the outer wall of the horizontal corrugated cardboard 33 and the vertical corrugated cardboard 35. The first cardboard 31 is fixedly installed in the inner wall of the carton body 1, and the second cardboard 37 is fixedly installed at the bottom of the carton body 1. The first cardboard 31 and the second cardboard 37 can protect the vertical corrugated cardboard 35 and the horizontal corrugated cardboard 33 in the middle.

[0030] A through groove 63 is provided on one side of the outer wall of the mounting shell 61. A pressing block 65 is fixedly installed on the outer wall of the sliding plate 64. The pressing block 65 passes through the inner wall of the through groove 63. The sliding plate 64 is slidably installed on the inner wall of the mounting shell 61. The position of the sliding plate 64 in the mounting shell 61 can be changed by pressing the block 65.

[0031] Figures 1-5 The second embodiment is shown. The main difference from the first embodiment is that an L-shaped plate 66 is fixedly installed on the top of the sliding plate 64. The top of the L-shaped plate 66 is fixedly connected to the inclined edge block 67. When the inclined edge block 67 is squeezed, it will move.

[0032] The other end of a set of springs 62 is fixedly connected to the carton body 1. The mounting shell 61 is fixedly installed on the outer wall of the carton body 1. One end of the outer wall of the snap-fit ​​shell 68 is fixedly installed on the outer wall of the box cover 2. When the box cover 2 rotates, it can drive the snap-fit ​​shell 68 to move.

[0033] Two first L-shaped reinforcing plates 4 and two second L-shaped reinforcing plates 5 are fixedly installed at the bottom of the carton body 1. The L-shaped reinforcing plates can further improve the structural strength and stability of the bottom of the carton.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] During operation, when the cardboard corner box carries goods, the weight of the goods is first transferred to the bottom of the box body 1. At this time, the bottom pressure-bearing component 3 begins to function. The first cardboard 31, as the part that directly bears the weight of the goods, distributes the pressure to the transverse corrugated cardboard 33. The corrugated structure of the transverse corrugated cardboard 33 itself has a certain compressive strength, while a set of transverse support rods 34 inside it further enhances the transverse support strength, enabling the transverse corrugated cardboard 33 to better withstand the transverse pressure from the goods. Next, the pressure is transmitted from the transverse corrugated cardboard 33 to the vertical corrugated cardboard 35. The corrugated structure of the vertical corrugated cardboard 35 works in conjunction with the vertical support rod 36 to effectively withstand the vertical pressure and evenly distribute the pressure onto the second cardboard 37. Finally, the second cardboard 37 transmits the pressure to the ground, thereby achieving effective load-bearing and pressure distribution of the goods' weight. This improves the load-bearing capacity of the bottom of the carton, reducing the problem of easy deformation and damage at the bottom of traditional cardboard corner boxes, preventing the goods inside the box from falling off the bottom, and improving the safety of goods transportation. At the same time, two first L-shaped reinforcing plates 4 and two second L-shaped reinforcing plates 5 are fixedly installed at the bottom of the carton body 1, further enhancing the structural strength and stability of the bottom of the carton. In conjunction with the bottom pressure-bearing component 3, they can better withstand the pressure of the goods and reduce the deformation and damage of the carton during transportation. When it is necessary to close the lid 2, the lid 2 is rotated downwards, causing the snap-fit ​​shell 68 to gradually approach the mounting shell 61. When the snap-fit ​​housing 68 contacts the beveled snap-fit ​​block 67, the beveled snap-fit ​​block 67 is squeezed by the snap-fit ​​housing 68, pushing the sliding plate 64 to slide within the mounting housing 61 and compressing the spring 62. After the snap-fit ​​housing 68 passes the beveled snap-fit ​​block 67, the sliding plate 64 returns to its original position under the elastic force of the spring 62, and the beveled snap-fit ​​block 67 snaps into the snap-fit ​​housing 68, thus securing the lid 2 to the carton body 1. When it is necessary to open the lid 2, press the pressing block 65 to move the sliding plate 64 within the mounting housing 61, causing the beveled snap-fit ​​block 67 to disengage from the snap-fit ​​housing 68, allowing the lid 2 to be easily opened.
