目的 为了促进农特产品销售，设计一种正六棱台上下复合式轻便纸质礼盒。方法 以传统竹木六棱食盒的盒型结构为设计原型，采用“T-X-T”三维成型方式进行盒型结构设计，通过提手设计和粘贴锁合结构来提高礼盒的便携性。利用SolidWorks软件对盒型结构进行力学模拟分析。结果 利用“T-X-T”模式分解主体盒型结构，可以得到准确边缘关系结构图。侧板粘贴成盒过程中，通过增加粘合面积，可以提高盒型抗压强度。在相同纸张用料的情况下，侧板成角的角度对盒型的外尺寸有重要影响。侧板成角的角度设计范围在60°～90°之间；分析得出立体成型后外尺寸计算公式。结论 所设计轻便纸盒为正六棱台上下复合式，美观大方。提手设计便携可折叠，反插式锁孔设计提高了盒盖的锁合能力。侧板采用粘贴成盒，提高了盒型抗压强度及堆码性能。

The work aims to design a composite portable paper gift box with regular hexagon to promote the sale of special agricultural products. The traditional bamboo-wood hexagonal food box structure was used as the design prototype. The "T-X-T" three-dimensional modeling method was used for the box structure design. The handle design and sticking locking structure were used to improve the portability of the gift box. The mechanical properties of the box structure were simulated and analyzed by Solidworks software. An accurate edge relational structure map could be obtained by decomposing the main box structure with the "T-X-T" model. The compressive strength of the box could be improved by increasing the adhesive area in the process of pasting side plate into box. In the case of the same paper consumption, the angle of the side board angle had an important influence on the outer size of the box. When the design range of the side plate angle was between 60° and 90°, the formula of the outer size after the three-dimensional modeling was obtained. The final design of the portable gift box is elegant and beautiful. Meanwhile, the handle design is portable and foldable. The reverse insertion lock hole design can improve the locking ability of the lid. When the side plate is pasted into a box, the compressive strength and stacking performance of the box could be improved.
