Description

折叠箱 技术领域
本发明涉及容器，具体涉及折叠箱。
背景技术
现有折叠箱有固定的侧板厚度及高度，在使用时，侧板要相对展开直立，四块侧板互锁，从而形成相对封闭的空间来容纳货物，而在货物清空后，箱体需要被回收，为了更大化节约成本，将箱体侧板进行折叠，而使得在同等的空间内能容纳更多的箱体回收。
在折叠箱的回收过程中，需要便于清洁，特别是当折叠箱用来装载蔬果生鲜等食品时，使用后清洁尤为重要。同时，箱体使用中，既要保证在其装载的货物时安全可靠，又要在箱内货物清空时侧板能简单快捷的解锁并折叠。
现有的折叠箱，例如专利申请WO2011062565A1所公开的折叠箱，箱体的侧板能实现快速的锁定，但箱体的把手安装在侧板外缘，当折叠箱在使用过程中往往会受到内载货物对侧板扩张力量，而把手需要上下移动的装配间隙，很容易导致把手部分变形而凸出侧板的外缘，在这样的情况下，箱体在搬运还是在使用过程中很容易触发到把手并让其解锁，给折叠箱带来安全隐患。另外这种折叠箱侧板上布置了额大量的加强筋来加强侧板的强度，这使得箱体使用过程中容易藏污纳垢，使用后也不利于快速清洁，不利于蔬果生鲜等食品卫生。

具体实施方式
以下将结合附图对本发明的较佳实施例进行详细说明，以便更清楚理解本发明的目的、特点和优点。应理解的是，附图所示的实施例并不是对本发明范围的限制，而只是为了说明本发明技术方案的实质精神。
图1是根据本发明的一实施例的折叠箱100的立体图，其中局部剖切以示出部分锁定机构。如图1所示，折叠箱100包括底板1，一对第一侧板2、2和一对第二侧板3、3。其中第一侧板2和第二侧板3分别铰接至底板1并可相对于底板1折叠。相邻的第一侧板和第二侧板通过锁定机构4可释放地相互锁定。较佳地，第一侧板和第二侧板均为双光面侧板。本实施例中，第一侧板比第二侧板短，故第一侧板也称为短侧板，而第二侧板也称为长侧板。长短侧板较佳地由例如高强度塑料等高强度材料制成。
本实施例中，锁定机构4包括把手41、锁定件42和设置于第二侧板3上的导 向特征31(例如图17-19所示的设有导向斜面的凸起31)，其中该把手可上下移动地安装于第一侧板2上。该锁定件42用于将相邻的第一侧板2和第二侧板3相互锁定。具体地，当第一侧板2和第二侧板3处于锁定状态时，把手41对锁定件42进行限位从而限制锁定件42使其不能运动，而当把手41向上(移动其他实施例中，也可向下移动)预定距离从而为锁定件42提供其运动所需的空间后，锁定件42能够与诸如导向斜面的导向特征配合，例如沿导向斜面运动，从而驱动锁定件42运动(回缩)而实现解锁，下文将进一步详细描述。
图2示出根据本发明的一实施例的锁定机构4的分解立体图。如图2所示，把手41中部为手持部，两端设有抵靠部411。抵靠部411上设有把手导向斜面4111。较佳地，把手41的两端还设有把手弹片412，把手弹片412用于驱使把手41在移动后复位。在把手41的两端还设有挂槽414，用于与第一侧板2上的挂钩25(如图3b所示)配合而使得把手41连接至第一侧板2并能够沿第一侧板2上下滑动。
还如图2所示，锁定件42的一端设有锁舌422，另一端设有V字形弹片421(也称为第一锁舌弹片，其它实施例中，第一锁舌弹片也可采用其它形状，只要其能够在上锁时驱使锁定件回弹即可)。锁舌422上设置有圆弧导向面。在锁定件42的外侧(较佳地在中部)设有第二锁舌弹片423，第二锁舌弹片423上设有限位凸起424和触发凸起425。这里，术语“外侧”指的是与折叠箱外部相同的一侧。在锁定件42上侧还设有第三锁舌弹片424(另一实施例中，第三锁舌弹片也可设置于锁定件的下侧)。第三锁舌弹片424用于当锁舌当处于完全释放(即锁舌处于锁定的伸出状态)而第一侧板处于折叠状态时，此时第一侧板向直立方向运动(箱体展开上锁)，锁舌将会沿着第二侧板的止挡部导向，迫使第三锁舌弹片424弹性变形，锁舌朝向第一侧板上缘摆动。当锁舌越过长侧板止挡部，第三锁舌弹片的外侧始终被限制在第一侧板相应的安装部中，依靠弹性复位将锁舌推入到第二侧板止挡部与第二侧板连接部之间，使得长侧板处于锁定状态。
在锁定件42的与V字形弹片421相同的一端设有与第一导向斜面4111对应的锁定导向斜面425(如图10所示)，当解锁时，锁定导向斜面425能够沿着把手导向斜面4111移动。
如图3a和3b所示，在第一侧板2的内壁上延伸出与第一侧板的内壁平行的一安装壁21。在侧板的内壁上还形成有挂钩25。组装时，把手41容纳于第一侧板的内壁与安装壁21之间形成的空间内并且挂钩25与挂槽414配合，从而把手能够沿 第一侧板2上下滑动。需要指出的是，这里的挂钩也可设置在把手上，相应地，挂槽设置在第一侧板上，同样也可实现相同的功能。
第一侧板2上还设有限位孔26和触发孔27(例如如图7和8所示)。第一侧板2的内腔设有限位凸筋22。第二侧板3设有触发部32(如图22所示)。其中，设置于锁定件42上的限位凸起424和限位孔26配合从而在使得锁定件42能够保持在解锁状态。触发凸起425和触发部32配合从而使得限位凸起424能够脱离限位孔26。限位凸筋22与V字形弹片配合，使得解锁时V字形弹片变形并在锁定时驱使锁定件42复位。
第二侧板3的内壁上在靠近第一侧板的位置处设置带有导向斜面311的凸起(也称为止挡部)31。第二侧板3左右两侧边缘垂直延伸出连接部33。在锁定状态下，锁定件42的一端(锁舌端)位于凸起31与连接部33之间并由凸起31和连接部33限位。
本发明的折叠箱的上锁和解锁(折叠或展开)的过程如下：当侧板折叠或展开直立时，位于第一侧板2上的锁舌圆弧面与第二侧板上的止挡部导向斜面相导向，便于锁舌向第一侧板中部回弹或朝向第一侧板上缘摆动。V字形弹片用于在锁定第一侧板与第二侧板时的向第一侧板外缘弹出的复位(锁舌圆弧面越过长侧板的止挡部后向长侧板方向弹出的复位)。第三锁舌弹片424用于当锁舌当处于完全释放(即锁舌处于锁定的伸出状态)而第一侧板处于折叠状态时，此时第一侧板向直立方向运动(箱体展开上锁)，锁舌将会沿着第二侧板的止挡部导向，迫使第三锁舌弹片424弹性变形，锁舌朝向第一侧板上缘摆动。当锁舌越过长侧板止挡部，第三锁舌弹片的外侧始终被限制在第一侧板相应的安装部中，依靠弹性复位将锁舌推入到第二侧板止挡部与第二侧板连接部之间，使得长侧板处于锁定状态。解锁时，首先将把手向上提起，从而为锁定件的运动提供避让空间，接着第一侧板向内推倒，锁舌沿着第二侧板的止挡部导向斜面迫使其向第一侧板向中部收缩，且当锁舌即将越过止挡部时，被压迫的第二锁舌弹片423复原并一起连同设置在第二锁舌弹片423上的限位凸起424弹出，进去到第一侧板的限位孔26中。此时，第二锁舌弹片423上的限位凸起424挂靠在第一侧板的限位孔26中，使得锁舌处于非锁定状态。上锁时，第一侧板再向直立方向运动，锁舌的触发凸起425触及长侧板端面边缘(即连接部33上的触发部32)，迫使锁舌触发凸起425后退并使得第二锁舌弹片423向箱体内部 方向变形的同时，锁舌的限位凸起424也脱离第一侧板的限位孔26，锁舌便被V字形弹片(第一锁舌弹片)的弹性复原推入到第二侧板的止挡部与第二侧板的连接部端面之间，从而使第一侧板和第二侧板处于锁定状态。
图24至30示出根据本发明的第二实施例的折叠箱的锁定机构5。如图24所示，把手51的两端设有夹持部513，当第一侧板2和第二侧板3处于锁定状态时，把手的两端分别通过夹持部513夹持两个锁定件52的一端(如图26所示)，而当把手向上或向下移动预定距离后并向内推第一侧板时，把手的两端的夹持部513脱离锁定件52(如图28所示)。
还如图24所示，锁定件52设有锁舌521和锁舌弹片522。锁舌521上设有长形铰链孔5211，从锁舌的朝向第二侧板的一端延伸出被夹持端523。锁舌弹片522的一端固定于锁舌521，另一端设有铰链销524。组装时，锁舌521通过销钉53可移动地连接于第一侧板，而锁舌弹片522铰接于第一侧板2，如图30所示。
当第一侧板2和第二侧板3处于锁定状态时，锁舌52的被夹持端夹持于把手的夹持部513，而锁舌52的另一端伸入第二侧板，具体伸入第二侧板上的凸起(止挡部)与连接部之间。解锁时，锁舌的被夹持端脱离把手的夹持部且锁舌与凸起的导向斜面配合，从而使得锁舌脱离第二侧板而实现解锁。具体地，解锁时，向上提起把手后，把手的夹持部脱离锁舌52，此时，向折叠方向(向折叠箱内部)推动侧板，锁舌端部与侧板的止挡部干涉，使得锁舌弹片被迫弹性变形(向内弯曲)，此时锁舌亦会沿着第二侧板止挡部斜面导向而向第一侧板中部回缩，实现解锁。锁舌越过止挡部后，凭借锁舌弹片的复原而使锁舌弹出并大致平行于第一侧板，当侧第一板直立上锁时，锁舌沿着侧板止挡部斜面导向使得锁舌弹片变形而向侧板中部缩回，越过止挡部后弹片复原，锁舌伸出，侧板处于上锁状态。
图31-32示出图1-23所示实施例的变型例。该实施例的锁定机构6与图1-23所示实施例不同之处主要在于把手6通过销轴611可转动地安装至第一侧板2，当侧板解锁时，把手61向内旋转，使把手最端部612与锁舌62分离错位，使得锁舌有向侧板中部回缩的空间。其余基本相同，在此不再详述。
需要指出的是，本发明的原理为：在锁定状态下，把手对锁定件进行限位从而使得相邻的两个侧板保持锁定状态，而在解锁时，把手移动，从而为锁定件提供避让空间，此时锁定件能够与导向特征配合而缩回第一侧板内。这里， 把手移动的方式包括上下移动、左右移动或围绕一轴线转动等任何合适的方式，只要把手移动能够为锁定件提供使其缩回第一侧板内的避让空间即可。
以上已详细描述了本发明的较佳实施例，但应理解到，在阅读了本发明的上述讲授内容之后，本领域技术人员可以对本发明作各种改动或修改。这些等价形式同样落于本申请所附权利要求书所限定的范围。
