请参阅图1-5，本发明提供了一种箱式缓冲盒结构，包括单一片式的塑料膜材1，塑料膜材1通过气柱模压线封合成多根气柱2和气道3，多根气柱6形成六个气柱区和四个非气柱区，封压完成后六个气柱区和四个非气柱区对折并通过塑料膜材1两侧设有的热压缝合线4热压封合成箱式缓冲盒；
气柱区包括前体板气柱区101，前体板气柱区101的多根气柱2顶端通过热封连接的堵气阀膜301均与气道3的内部连通，前体板气柱区101的多根气柱2底端与底板气柱区102的多根气柱2顶端连通，底板气柱区102的多根气柱2底端与后体板气柱区103的多根气柱2顶端连通，后体板气柱区103的多根气柱2底端与盖体气柱区104的多根气柱2的顶端连通，后体板气柱区103的两侧对称设有左体板气柱区105和右体板气柱区106，组成左体板气 柱区105的多根相邻气柱2之间的气柱模压线和组成右体板气柱区106的多根相邻气柱2之间的气柱模压线均开设有多个用于其气柱2相互连通的缺口202，盖体气柱区104的多根气柱2的底端通过模压线封合。
优选的，非气柱区包括通过模压线分别热封于底板气柱区102两侧的第一非气柱区107和第二非气柱区108，非气柱区还包括通过模压线分别热封于盖体气柱区104两侧的第三非气柱区109和第四非气柱区110，且第三非气柱区109的顶端和第四非气柱区110的顶端均设有切口111，非气柱区在气柱2内充气后，其内部并不会注入气体，方便快速盒体一次充气成型，并可将非气柱区折入盒体内或盒体外部，使得成型的盒体外壁或内壁没有突起，保持光滑。
优选的，前体板气柱区101的多根气柱2与底板气柱区102的多根气柱2连通处、底板气柱区102的多根气柱2与后体板气柱区103的多根气柱2连通处和后体板气柱区103的多根气柱2与盖体气柱区104的多根气柱2连通处均设有模压点201，通过设有的模压点201方便气柱区充气后的折叠。
优选的，位于左体板气柱区105最右侧的一根气柱2通过开设的缺口202与位于后体板气柱区103最左侧的一根气柱2相互连通，位于右体板气柱区106最左侧的一根气柱2通过开设的缺口202与位于后体板气柱区103最右侧的一根气柱2相互连通，且位于左体板气柱区105内的多个缺口202和位于右体板气柱区106内的多个缺口202位置均不相对，左体板气柱区105和右体板气柱区106利用后体板气柱区103左右两边最边气柱2供气，同时左体板气柱区105之间的气柱2和右体板气柱区106之间的气柱2通过缺口202相互连通，便于气体进入各自气柱2内。
优选的，气道3的顶端中部设有与其内部连通的充气口302，充气口302的内部热封有单向气阀303，可通过气泵连接气管和充气口302向气道3内注入气体，单向气阀303可有效防止充入气柱2内的气体通过充气口302漏出。
优选的，第一非气柱区107与第二非气柱区108的尺寸相同，第一非气柱区107和第二非气柱区108长度与底板气柱区102的长度相等，第一非气柱区107和第二非气柱区108宽度分别与左体板气柱区105的宽度和右体板气柱区106的宽度相等，且第一非气柱区107、第二非气柱区108、第三非气柱区109和第四非气柱区110的中部均设有三角状压痕线，在六个气柱区内的气柱2充入气体后，可快速形成盒体，未进气的第一非气柱区107、第二非气柱区108、第三非气柱区109和第四非气柱区110可以折入盒体内或盒体外部。
优选的，塑料膜材1远离气道3的一端粘接有用于封盖的双面不干胶401，在盒体内存放合适尺寸的物品后，利用双面不干胶401可快速将盖体气柱区104与前体板气柱区101的内侧进行粘固定。
具体使用时，本发明一种箱式缓冲盒结构，将两层塑料膜材1叠合在热封模上压出多根气柱模压线、气道3的模压线和非气柱区的压痕线，形成对应六个的气柱区、四个非气柱区及一根气道3，并在六个气柱区气柱每根气柱2连通处热压出圆形的模压点201，随后利用切刀将左体板气柱区105与第三非气柱区109之间较宽的模压线和右体板气柱区106与第四非气柱区110之间边缘热合连接并破口，形成切口111，再将位于前体板气柱区101两侧的两根热压缝合线4分别与左体板气柱区105的一侧热压缝合线4和右体板气柱区106一侧的热压缝合线4进行热压缝合，形成平面状的口袋型袋体，通过气泵向充气口302内充入气体，气体通过单向气阀303进入气道3内部，气道3内注入气体后通过堵气阀膜301进入前体板气柱区101的多根气柱2内，由于前体板气柱区101、底板气柱区102、后体板气柱区103和盖体气柱区104的气柱2均依次连通，继而气体可快速注入五个气柱区的气柱2内，同时后体板气柱区103位于两侧的两根气柱2通过缺口202分别与左体板气柱区105和右体板气柱区106连通，继而注入后体板气柱区103内部气体的同时，气 体也会通过缺口202快速进入左体板气柱区105和右体板气柱区106内，随着气体的不断注入，袋体则变成立体盒形状，同时未通入气体的第一非气柱区107和第二非气柱区108通过三角状压痕线分别向盒体两侧盒壁内侧或外侧折入，使得成型的盒体外壁或内壁保持光滑，且第一非气柱区107和第二非气柱区108基本能平贴于外箱的内外表面，从而增加内部容置的比例和空间利用率，然后便可以通过成型后的盒体对合适尺寸的物品进行存放了，物品放入盒内后，将第三非气柱区109和第四非气柱区110均向盖体气柱区104内侧进行折叠，再撕下塑料膜材1一端外侧的双面不干胶401的离型纸撕下，盖体气柱区104向盒口处折叠，第三非气柱区109和第四非气柱区110均插入盒体的内部并分别与盒体的两侧内壁平滑接触，最后将双面不干胶401的胶面与前体板气柱区101的内侧进行粘固定，完成物品的包装，同时粘接后形成盖体的盖体气柱区104也不会与盒体发生脱离，起到了一定的防盗作用和盒口防变形的作用。
且采用该结构的盒体在使用的过程中，由于气道3充气口302处的单向气阀303不能做到完全100％的密封，盒体使用较长时间后，会普遍存在气体通过单向气阀303最终渗漏到外界的问题，所以本方案将充气口302设计到盒口的前体板气柱区101的中间位置，一是便于使用者快速找到，二是便于充气后方便将凸起的气道3完全热封，让气道3中的空气通过堵气阀膜301进入到气道3后，无法再渗漏到外界，达到完全保气的目的，提高盒体的使用寿命。
应补充说明的是:盒体在此结构基础之上，还可以将塑料膜材1表面贴合软性基材(例如：贴合纸皮、无纺布等材料)，增强产品结构的耐穿刺性能，有效的降低箱体和充气缓冲体综合生产制作成本，实际产品应用于快递物流运输行业，实现充气袋与盒体结合为一体的方式，使得本充气式快递盒具有成本低、轻便、抗摔防震的功能。还可以通过将箱体气柱区各个气柱2都用 交错分布的缺口202连通，对盒体进行充放气重复使用，进而解决了现有技术中快递包装产品成本高，不能很好的适应多种规格的内容物，无法重复使用，更不能防摔抗震的技术问题。
同时气柱区的气柱2和气道3可全部如图3所示3种方式中的其中一种进行纵向热压成型，每个气柱2之间的模压线也均通过缺口202连通，也可全部如图4所示3种方式中的其中一种进行横向热压成型，每个气柱2之间的模压线也可通过缺口202连通，还可全部如图5所示3种方式中的其中一种进行竖直向热压成型，每个气柱2之间的模压线也能通过缺口202连通，且充气口302如图3、4和5所示，可以安装带盖的充气嘴对充气口302堵住，气道3也可通过一个单向气阀303与气柱区其中一根气柱2进行连通，气道3还可通过多个单向气阀303与气柱区对应的气柱2进行连通，在气道3发生破损时，各个气柱2并不会漏气，提高缓冲盒的使用寿命，同时上述三种的方式都可实现对盒体进行充放气的重复使用。
