Description

Technical Field

[0001] The utility model relates to the technical field of cartons, in particular to a drop-resistant corrugated paper box. Background Art

[0002] Cartons are the most widely used packaging products. Depending on the materials used, corrugated cardboard is a multi-layer adhesive body. It is composed of at least one layer of wavy core paper interlayer and one layer of cardboard. It has high mechanical strength and can withstand collisions and falls during transportation. As an indispensable part of modern logistics, it bears the important responsibilities of containing, protecting products and being beautiful.

[0003] After searching, the patent number is CN210391851U, and the name is a utility model of a drop-resistant express corrugated paper box, including an outer shell, an inner lining, a corrugated layer, a filling layer and a triangular layer. Through research and analysis, it is found that although the paper box has advantages such as high strength and is not easy to deform during express transportation, it still has the following disadvantages to a certain extent;

[0004] For example, corrugated boxes are in all-round contact and collision with external objects and various factors for a long time, and the corrugated boxes cannot be effectively buffered, protected and fixed. As a result, the impact energy cannot be effectively absorbed and dispersed during the transportation of the corrugated boxes, resulting in low shock absorption performance of the corrugated boxes. The use of corrugated boxes is restricted, and the anti-fall effect is lacking, which makes them easily damaged and affects their service life. In order to solve the above technical problems, it is necessary for us to design a drop-resistant corrugated box to solve the above problems. Utility Model Content

[0008] Preferably, there are several tension springs, and the tension springs are arranged at equal distances.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] 1. The utility model realizes the buffering support of the intermediate gap between the cover plate and the box cover by the cooperation of the energy storage spring, the cover plate, the guide rod and the limit plate.

[0020] See also Figure 2 and Figure 3 The load-bearing mechanism 6 includes an energy storage spring 7, which is fixedly connected to the inner cavity of the box cover 5. A cover plate 8 is fixedly connected to the bottom of the energy storage spring 7. The cover plate 8 extends to the inner cavity of the carton 1 and contacts the top of the inner box 2. By setting the cover plate 8, the inner box 2 can be sealed and protected, and the bottom of the energy storage spring 7 can be supported at the same time.

[0021] See also Figure 3 A guide rod 9 is welded to the top of the cover plate 8. The top of the guide rod 9 passes through the energy storage spring 7 and the box cover 5 in sequence and is welded with a limiting plate 10. The guide rod 9 is movably connected to the inner wall of the box cover 5. By setting the guide rod 9, the energy storage spring 7 can be guided to move vertically to avoid deviating from its movement trajectory. By setting the limiting plate 10, the top of the guide rod 9 can be limited, thereby improving the use efficiency of the guide rod 9.

[0022] See also Figure 4 , Figure 5 and Figure 6The anti-fall mechanism 3 includes an annular tube 11, which is welded to the bottom of the bottom plate 4, a reset spring 12 is fixedly connected to the inner cavity of the annular tube 11, a push plate 13 is fixedly connected to the bottom of the reset spring 12, a slide bar 14 is welded to the bottom of the push plate 13, the bottom of the slide bar 14 is fixedly connected to the inner wall of the carton 1, a tension spring 15 is fixedly connected to the inner wall of the carton 1, a support plate 16 is fixedly connected to one side of the tension spring 15, a connecting rod 17 is movably connected to the side of the support plate 16 opposite to the annular tube 11 through a rotating shaft, a buffer airbag 18 is arranged on one side of the support plate 16, by arranging the push plate 13, the slide bar 14 and the reset spring 12 can be indirectly connected, so that the annular tube 11 is reset, and by arranging the connecting rod 17, the support plate 16 can be indirectly connected to the annular tube 11, so that the support plate 16 can have a certain moving space.

[0023] See also Figure 4 and Figure 5 One end of the slide rod 14 passes through the annular tube 11 and is movably connected to the inner wall of the annular tube 11. The opposite side of the buffer airbag 18 contacts the surface of the inner box 2. By setting a tension spring 15, the external force borne can be dispersed and buffered, which facilitates the return of the support plate 16.

[0024] See also Figure 4 There are several tension springs 15 , which are arranged at equal distances. By setting the slide bar 14 , the annular tube 11 can be stably supported, so that the rear side of the annular tube 11 can be balanced during movement.

[0025] When in use, when the box cover 5 collides with the outside, external pressure is applied between the box cover 5 and the cover plate 8, and the gap space is buffered and supported by the energy storage spring 7, and the position of the cover plate 8 is buffered. The energy storage spring 7 pushes the cover plate 8 to generate tension to squeeze the top of the inner cavity of the inner box 2, and positions the top of the inner box 2, thereby providing buffering protection for the inside of the inner box 2. When the carton 1 collides with the outside, the bottom plate 4 is placed and moves downward, pushing the annular tube 11 and the push plate 13 close to each other to squeeze the reset spring 12. During the downward movement, the annular tube 11 simultaneously pulls the support plate 16 to move horizontally, so that the support plates 16 are close to each other and squeeze the buffer airbag 18 to be in close contact with the inner box 2, so as to provide more stable limited support for the inner box 2. The reset spring 12 releases energy under the elastic force to provide buffering for the annular tube 11, which can reduce the vibration of the position where the bottom plate 4 is placed. The tension spring 15 can provide all-round buffering support for the surface of the carton 1 to prevent compression and deformation, and the buffer airbag 18 can alleviate the impact or vibration of the inner box 2 while limiting.

[0026] In summary: the anti-fall corrugated paper box, through the cooperation of the paper box 1, the inner box 2, the anti-fall mechanism 3, the placement bottom plate 4, the box cover 5 and the load-bearing mechanism 6, solves the problem that the corrugated paper box has low shock absorption performance and lacks anti-fall effect.
