Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a paper product packaging box with anti-fall protection. Background Art

[0002] With the gradual improvement and perfection of environmental protection concepts in today's society, and with the advantages of wide adaptability, recyclability and low cost, paper products have gradually replaced various plastic products that are not easy to decompose naturally in life and become an important material for daily necessities. However, due to defects such as paper products are not strong enough, they are easy to be damaged or deformed, and are easily affected by moisture during storage. When the outer packaging box of paper products falls or is collided, the paper products are easy to move in the packaging box, causing mutual squeezing and deformation.

[0003] At present, paper product packaging usually only considers protecting it from moisture, while ignoring the deformation of paper products caused by collision during transportation and storage. However, the deformation of paper products will affect their aesthetics and assembly effect.

DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example: Figure 1-4 As shown, a paper product packaging box with anti-fall protection includes a packaging box body 1 and a box cover 2. A bottom plate 11 is slidably installed on the inner bottom surface of the packaging box body 1, and a plurality of limit strips 13 are slidably installed on the inner surface of the packaging box body 1. A pressure plate 7 is provided on the inner surface of the packaging box body 1, and a first airbag 9 is fixedly installed on the lower surface of the pressure plate 7. A fixing bolt 4 is pierced on the surface of the box cover 2.

[0022] A second airbag 12 is fixedly installed on the inner bottom surface of the packaging box body 1, and the upper surface of the second airbag 12 is fixedly connected to the bottom surface of the bottom plate 11. A plurality of slide grooves 10 are provided on the inner surface of the packaging box body 1, and the bottom plate 11 is slidably connected to the inner surface of the slide groove 10. When the packaging box body 1 is hit or falls, the second airbag 12 provides bottom cushioning for the internal paper products, and when the second airbag 12 shakes, the bottom plate 11 slides up and down along the slide groove 10 to relieve the impact force.

[0023] A hollow connecting groove 16 is fixedly installed on the outer surface of the packaging box body 1, and the connecting groove 16 is connected to the interior of the packaging box body 1. A plurality of springs 14 are fixedly installed on the inner surface of the connecting groove 16. A slider 15 is fixedly installed at the end of the spring 14. The end of the slider 15 is fixedly connected to the limit strip 13. The slider 15 is slidably connected to the packaging box body 1 and the connecting groove 16.

[0024] After stacking the paper products on the upper surface of the bottom plate 11, select the limit strip 13 according to the height of the paper products, push the limit strip 13 into the connecting groove 16, so that the spring 14 is squeezed, place the pressure plate 7 under the limit strip 13 and release the limit strip 13. At this time, the spring 14 restores its original length, and the limit strip 13 returns to its original position to limit the position of the pressure plate 7 and prevent it from moving up.

[0025] The pressure plate 7 is placed on the upper surface of the paper product inside the packaging box body 1, and a valve core 17 is fixedly installed on the upper surface of the pressure plate 7. The valve core 17 is connected to the first air bag 9. The width of the pressure plate 7 is greater than the distance between the two limit strips 13, and the width of the pressure plate 7 is smaller than the internal width of the packaging box body 1. The first air bag 9 is inflated through the valve core 17 until it squeezes the surface of the paper product placed below, providing an upper buffer for the paper product.

[0026] A connecting ring 5 made of soft rubber is fixedly installed on the top of the inner surface of the packaging box body 1, and a connecting block 6 is fixedly installed on the lower surface of the box cover 2. The width of the connecting block 6 is consistent with the width of the inner surface of the connecting ring 5. The box cover 2 is pressed down so that the edge of the connecting block 6 is in close contact with the connecting ring 5, and the box cover 2 is tightly connected to the packaging box body 1 through friction.

[0027] The fixing bolt 4 is threadedly connected to the box cover 2 and the connecting block 6. The fixing bolt 4 passes through the connecting block 6 downward. The lower surface of the fixing bolt 4 is rotatably installed with a limiting member 8. After closing the box cover 2, the fixing bolt 4 is screwed downward to make the limiting member 8 contact the upper surface of the pressing plate 7. The pressing plate 7 is pressed downward to enhance the extrusion tightness between the first airbag 9 and the upper surface of the paper product.

[0028] Handles 3 are hingedly connected to the outer surfaces of both sides of the packaging box body 1, and the packaging box can be easily taken out by the handles 3 to reduce the probability of it falling.

[0029] Working principle: When using this anti-fall protection paper product packaging box, the paper products are stacked and placed on the upper surface of the bottom plate 11. The second airbag 12 provides a bottom buffer for the internal paper products. When the second airbag 12 shakes, the bottom plate 11 slides up and down along the slide groove 10 to relieve the impact force. The limit strip 13 is selected according to the height of the paper product, and the limit strip 13 is pushed into the connecting groove 16 so that the spring 14 is squeezed. The pressure plate 7 is placed under the limit strip 13 and the limit strip 13 is released. At this time, the spring 14 restores its original length. The limit strip 13 returns to its original position to limit the position of the pressure plate 7 and prevent it from moving up. The first air bag 9 is inflated through the valve core 17 until it squeezes the surface of the paper product placed below to provide an upper buffer for the paper product. The box cover 2 is pressed down to make the edge of the connecting block 6 in close contact with the connecting ring 5, and the box cover 2 is tightly connected to the packaging box body 1 through friction. After closing the box cover 2, the fixing bolt 4 is screwed downward to make the limit piece 8 in contact with the upper surface of the pressure plate 7. The pressure plate 7 is pressed down to enhance the squeezing tightness between the first air bag 9 and the upper surface of the paper product.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
