[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the following further details the present application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and do not limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion.

[0024] In the related art, existing packaging boxes are usually paper products, which have weak compressive and shock-absorbing capabilities. They are easily damaged due to external factors during transportation, resulting in economic losses, affecting the appearance and beauty of the packaging, and unable to adjust the size of the items in the box. As a result, during transportation, the items shake inside the packaging box, causing damage to the items.

[0025] Based on this, in order to improve the problems in the related art that existing packaging boxes are usually paper products, which have weak compressive and shock-absorbing capabilities, are easily damaged due to external factors during transportation, resulting in economic losses, affecting the appearance and beauty of the packaging, and unable to adjust the size of the items in the box, causing the items to shake inside the packaging box and getting damaged, the embodiments of the present application provide the following solutions.

[0026] Please refer to Figures 1 to 4 , an impact-resistant packaging box includes a box body 1, a buffer mechanism 2, and a fixing mechanism 3. The box body 1 is used for storing items. The buffer mechanism 2 is used to buffer the force generated by the collision during the transportation and movement of the packaging box. The fixing mechanism 3 is used to adjust the size inside the box body 1 according to the size and volume of the items to be stored, so that the items are stored more stably inside the packaging box.

[0027] Please refer to Figures 1 to 3 , the fixing mechanism 3 includes a moving plate 31, a telescopic push rod 32, and a twisting handle 33. A receiving plate 4 is arranged above the bottom end inside the box body 1. A sliding groove 41 is formed on the receiving plate 4. The moving plate 31 is slidably connected in the sliding groove 41, and both side surfaces of the two ends of the moving plate 31 are in contact with the two sides of the inner wall of the box body 1. The telescopic push rod 32 penetrates through the side wall of the box body 1 and abuts against the moving plate 31. The twisting handle 33 is fixedly connected to the end of the telescopic push rod 32 far from the moving plate 31, and the twisting handle 33 is located outside the box body 1. A second buffer spring 6 is fixedly installed on the bottom wall inside the box body 1. The end of the second buffer spring 6 far from the bottom wall of the box body 1 is fixedly connected to the receiving plate 4. A top cover 7 is arranged at the position near the opening at the top of the box body 1. A handle 8 is fixedly installed on the top cover 7. A hinge plate 9 is fixedly installed at the connection between the top cover 7 and the box body 1. A plug plate 10 is fixedly connected to the front end surface of the top cover 7. A plug box 11 is fixedly connected to the front end surface of the box body 1. The plug plate 10 is inserted into the plug box 11.

[0028] With such a setting, when the user places an item inside the box body 1, first, according to the size and volume of the item to be stored, the user adjusts the internal size of the box body 1. First, rotate the turning handle 33 to make the telescopic end of the telescopic push rod 32 rotationally connected to the turning handle 33 extend or shorten, thereby driving the moving plate 31 fixedly connected to the telescopic push rod 32 to move along the sliding groove 41 opened on the receiving plate 4. When adjusted to the appropriate position, then rotate the turning handle 33 to fix the moving plate 31. Subsequently, press down the top cover 7 provided at the top opening of the box body 1 by rotating it through the hinge plate 9, so that the plug board 10 provided on the top cover 7 is inserted into the plug box 11 provided on the box body 1, making the box body 1 in a closed state. At this time, the user lifts the box body 1 through the handle 8 provided on the top cover 7 and moves it to an appropriate position for placement or transportation.

[0029] The effect of such a setting is that through the mutual cooperation of the moving plate 31, the telescopic push rod 32, the sliding groove 41, and the turning handle 33, the user can, according to the size of the item to be stored, move the moving plates 31 on both sides inside the box body 1 by rotating the turning handle 33 to adjust the internal size of the box body 1, making the item abut against the inner wall of the box body 1. Furthermore, during the transportation and movement of the packaging box, the item stored in the packaging box is more stable and will not easily shake, causing the item to collide with the inside of the packaging box, resulting in damage to the item and economic losses. By providing the handle 8 on the top cover 7, it is convenient for the user to move the box body 1 to an appropriate position through the handle 8.

[0030] Please refer to Figure 1 and Figure 4 Inside the box body 1, a supporting vertical plate 5 is further provided, and the supporting vertical plate 5 is fixedly installed on the inner side of the corner of the box body 1. The bottom wall inside the box body 1 is fixedly installed with a second buffer spring 6, and one end of the second buffer spring 6 far from the bottom wall of the box body 1 is fixedly connected to the receiving plate 4. The buffer mechanism 2 includes a connecting circular plate 21, a first buffer spring 22, and a buffer plate 23. The connecting circular plate 21 is fixedly connected to the outer wall of the box body 1, one end of the first buffer spring 22 is fixedly connected to the outer surface of the connecting circular plate 21, and the buffer plate 23 is fixedly connected to the other end of the first buffer spring 22.

[0031] With such a setting, when the packaging box is collided during transportation or when it is lifted and moved, the buffer plate 23 fixedly connected to the first buffer spring 22 will be collided first, thereby squeezing the first buffer spring 22, causing the first buffer spring 22 to deform due to the acting force generated by the collision, and further reducing the impact of the acting force generated by the collision on the packaging box body. When the box body 1 falls from a height, at this time, the second buffer spring 6 between the inner bottom wall of the box body 1 and the bearing plate 4 will be deformed by the extrusion of the bearing plate 4, thereby buffering the acting force generated when the box body 1 hits the bottom. At the same time, the support vertical plate 5 fixedly installed inside the corner of the box body 1 will support the whole box body 1.

[0032] The effect of such a setting is that through the mutual cooperation of the connecting circular plate 21, the first buffer spring 22 and the buffer plate 23, when the packaging box collides during transportation and movement, the buffer plate 23 is forced to squeeze the first buffer spring 22, causing the first spring to deform, and further reducing the impact of the acting force generated by the collision on the packaging box body, prolonging the service life of the packaging box, preventing the packaging box from deforming and affecting the appearance and beauty of the package. At the same time, it can also reduce the extrusion of the inner wall of the packaging box on the items, making the items stored inside the packaging box not easily damaged, improving the transportation quality. By fixedly installing the support vertical plate 5 inside the corner of the box body 1, the overall structure of the box body 1 is made more stable, thereby improving the compressive capacity of the box body 1.

[0033] As can be seen from the above, the working principle of this application is as follows:

[0034] When the user places the items inside the box body 1, first adjust the size inside the box body 1 according to the size and volume of the items to be stored. First, rotate the twisting handle 33, so that the telescopic end of the telescopic push rod 32 rotationally connected to the twisting handle 33 extends or shortens, thereby driving the moving plate 31 fixedly connected to the telescopic push rod 32 to move along the sliding groove 41 opened on the bearing plate 4. When adjusted to the appropriate position, then rotate the twisting handle 33 to fix the moving plate 31. Subsequently, press down the top cover 7 provided on the top opening of the box body 1 by rotating it through the hinge plate 9, so that the insertion plate 10 provided on the top cover 7 is inserted into the insertion box 11 provided on the box body 1, making the box body 1 in a closed state. At this time, the user lifts the box body 1 through the handle 8 provided on the top cover 7 and moves it to the appropriate position for placement or transportation;

[0035] When the packaging box is collided during transportation or lifted and moved, the buffer plate 23 fixedly connected to the first buffer spring 22 will be collided first, thereby squeezing the first buffer spring 22, causing the acting force generated by the collision of the first buffer spring 22 to deform, and further reducing the impact of the acting force generated by the collision on the packaging box body. When the box body 1 falls from a height, at this time, the second buffer spring 6 between the inner bottom wall of the box body 1 and the receiving plate 4 will be deformed by the extrusion of the receiving plate 4, thereby buffering the acting force generated when the box body 1 lands. At the same time, the support vertical plate 5 fixedly installed inside the corner of the box body 1 will support the whole box body 1.

[0036] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
