Description

Technical Field

[0001] The utility model belongs to the technical field of packaging boxes, and in particular relates to a corrugated paper packaging box. Background Art

[0002] Corrugated cardboard is a multi-layered bonded structure consisting of at least one corrugated core paper layer and one cardboard layer. It exhibits excellent elasticity and ductility and is primarily used to manufacture cartons, carton inserts, and other packaging materials for fragile goods. Corrugated boxes are rigid paper containers made from corrugated cardboard. For over half a century, due to their superior performance and processability, corrugated boxes have gradually replaced wooden boxes and other transport packaging containers, becoming the mainstay of transportation packaging. In addition to protecting goods and facilitating storage and transportation, they also enhance product aesthetics and promote product promotion. Corrugated boxes are environmentally friendly and facilitate handling and transportation.

[0003] Corrugated cardboard boxes are bound to shake during transportation. When existing corrugated cardboard boxes are stacked, they may slide when shaking, causing the goods inside to fall over and be damaged, increasing the risk of damage to the goods. Utility Model Content

[0004] The present invention addresses the problem in the prior art that corrugated paper boxes may slide during transportation, causing the goods inside to fall over and be damaged. The following technical solutions are proposed:

[0005] A corrugated cardboard packaging box includes a box shell, a box cover is provided on the top of the box shell, a fixed plate is fixedly connected to the top edge of the box cover, a threaded rod is threaded through the side of the fixed plate, a movable plate is fixedly connected to one side of the surface of the threaded rod, a knob is fixedly connected to one end of the threaded rod, and a fixed block is fixedly connected to one end of the threaded rod located on the movable plate.

[0006] As a preferred embodiment of the above technical solution, a plurality of quadrangular blocks are fixedly connected to the top of the box cover, an oblique groove is provided at the diagonal corner of the fixed plate of the box cover, and box lifting openings are provided on both the left and right sides of the box shell.

[0007] As a preferred embodiment of the above technical solution, the four corners inside the box shell are fixedly connected to fixed columns, and limiting grooves are provided on the sides of the fixed columns.

[0008] As a preferred embodiment of the above technical solution, a plurality of limiting openings are provided at the bottom of the box shell, and the plurality of limiting openings correspond to the quadrangular pyramid blocks in a vertical direction.

[0009] As a preferred embodiment of the above technical solution, two fixing plates are provided on the top of the box cover, which are located at diagonal positions of the box cover.

[0010] As a preferred embodiment of the above technical solution, the fixing column is made of rubber.

[0011] The beneficial effects of the utility model are:

[0012] (1) The threaded rod on the fixed plate is rotated to tighten the movable plate to clamp the two stacked corrugated cardboard boxes. At the same time, the position of the four-sided table block prevents the stacked corrugated cardboard boxes from sliding, reducing the loss caused by the sliding and tipping of the goods;

[0013] (2) The grooves on the fixing columns prevent the corrugated cardboard boxes containing goods from shaking inside. At the same time, the fixing columns are made of rubber, which reduces the collisions that occur during shaking and provides secondary protection inside the box shell.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] like Figures 1 to 2 As shown, a corrugated cardboard packaging box includes a box shell 1, a box cover 2 is provided on the top of the box shell 1, and a fixed plate 3 is fixedly connected to the top edge of the box cover 2. A threaded rod 4 is threaded through the side of the fixed plate 3, and a movable plate 5 is fixedly connected to one side of the surface of the threaded rod 4. A knob 6 is fixedly connected to one end of the threaded rod 4, and a fixed block 7 is fixedly connected to one end of the threaded rod 4 located on the movable plate 5; when the corrugated cardboard boxes need to be stacked, after the placement is completed, the knobs 6 on the two diagonal corners can be rotated to drive the threaded rod 4 and the movable block to slide on the surface of the box shell 1, and continuously approach the fixed block 7 until they fit together, so as to fix the stacked corrugated cardboard boxes and prevent them from shaking.

[0020] like Figures 1 to 2As shown, a plurality of quadrangular blocks 8 are fixedly connected to the top of the box cover 2, an inclined slot 9 is provided at the diagonal corner of the fixed plate 3 of the box cover 2, and box lifting openings 10 are provided on both the left and right sides of the box shell 1; the inclined slot 9 is mainly for placing the space for the threaded rod 4, and the box lifting opening 10 is used to lift the corrugated cardboard box.

[0021] like Figure 2 As shown, the four corners inside the box shell 1 are fixedly connected with fixing columns 11, and the side of the fixing columns 11 is provided with limiting grooves 12; the corrugated cardboard box filled with goods is placed inside the box shell 1, and the goods are protected by the limiting grooves 12 on the fixing columns 11. The fixing columns 11 are made of rubber material. When shaking and collision occur, the internal rubber can provide buffering. At the same time, the limiting grooves 12 fit the corrugated cardboard box, and the box shell 1 is provided for external protection, which reduces a lot of impact force and realizes the protection of the goods.

[0022] like Figures 1 to 3 As shown, the bottom of the box shell 1 is provided with a plurality of limiting openings 13, and the plurality of limiting openings 13 correspond to the quadrangular pyramid blocks 8 in the vertical direction. When placing, the hypotenuse of the quadrangular pyramid block 8 can be conveniently aligned by the user, making placement easy.

[0023] like Figure 1 As shown, two fixing plates 3 are provided on the top of the box cover 2, which are located at diagonal positions of the box cover 2; there are two devices for fixing.

[0024] like Figure 2 As shown, the fixing column 11 is made of rubber material and is used to reduce the impact force of collision.

[0025] Working principle:

[0026] When the user uses the device, he first puts the corrugated cardboard box filled with goods into the box shell 1, and protects the goods through the limit groove 12 on the fixed column 11. The fixed column 11 is made of rubber. When shaking and collision occur, the internal rubber can be used for buffering. At the same time, the limit groove 12 fits the corrugated cardboard box, and the box shell 1 protects the outside, reducing a lot of impact force and achieving protection of the goods. After placing the goods, cover the box lid 2. When the same operation needs to be performed to stack corrugated cardboard boxes, the bottom opening of the box shell 1 is aligned with the four-sided pyramid block 8 through the lifting box mouth 10. At the same time, the hypotenuse of the four-sided pyramid block 8 can be convenient for the user to align, making placement easy. When placement is completed, the knobs 6 on the two diagonal corners can be turned to drive the threaded rod 4 and the movable block to slide on the surface of the box shell 1, and continuously approach the fixed block 7 until it fits, so as to fix the stacked corrugated cardboard boxes and prevent shaking.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
