Description

可折叠容器 技术领域
本发明涉及一种容器，具体涉及一种可折叠周转箱。
背景技术
为了降低物流成本，可折叠容器被越来越多的用于物流运输及包装。这些可折叠容器一般由两对相对的侧板和一个底座组成，侧板可相对于底座折叠。在容器里面装有货物的情况下，加速或转弯时货物会对容器的侧板产生侧向冲击力。因此，要提高可折叠容器的强度，重点是提高可折叠容器的侧板强度。目前有许多方案可以提高侧板强度，例如，改进侧板材料、将侧板通过两块板焊接形成两侧光面的侧板以及在这种焊接的两侧光面侧板之中增加钢管或铝管。
然而，在实际应用中，具有加强侧板的可折叠容器的强度在一些场合中不能满足要求，例如当周转箱容纳较重的货物时。发明人经过深入研究发现，对具有加强侧板的可折叠容器的强度影响较大的因素之一为相邻侧板之间的咬合结构。
由于相邻侧板之间设有咬合结构，该咬合结构也是冲击力直接作用的对象。因此，在侧板本身强度提高的情况下，可折叠容器的整体强度一定程度上取决于相邻侧板之间的咬合结构的强度。
目前的大型可折叠容器咬合结构一般为T字槽或燕尾槽，或者两种类型的槽穿插使用，这些咬合结构并不是沿着侧板之间的连接位置连续布置的。如图20所示，侧板100为现有技术中的带有锁扣结构的大型可折叠容器的侧板的一部分。侧板100设有咬合结构1002和锁扣结构安装位置1001。由于要设置锁扣结构，因此在锁扣结构安装位置1002处没有咬合结构。因此，一般的塑胶类大型折叠容器咬合情况为上部有槽咬合，紧接着被锁扣的锁舌所隔断，然后锁舌下方到设置咬合结构大致排列到底座位置。根据理论，这些咬合所受到的冲击力分布图大致如图1所示，位于锁扣上方的咬合结构承受的冲击力要远远大于锁扣下方的咬合结构，实际使用中，也证实了这一理论，咬合结构脱出或损坏的情况多发生于上侧咬合结构。
随着市场对产品性能要求的逐渐提高，如何设置侧板之间的咬合结构成为提高整个可折叠容器强度的关键。

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。
本发明的可折叠容器包括：底座1、侧板2、侧板3、侧板4和侧板5。其中，侧板2和侧板4为相对侧板。侧板3和侧板5为相对侧板。侧板2与侧板3和侧板5为相邻侧板。侧板4与侧板3和侧板5为相邻侧板。其中，在两个相邻侧板的连接处设置有咬合结构和锁扣结构。咬合结构用于连接两相邻侧板。锁扣结构用于锁紧两相邻侧板，从而当锁扣结构锁紧时，两相邻侧板相互固定，当锁扣结构打开时，两相邻侧板可以彼此分离。在以下优选实施例中，如图19所示，每一块侧板都由外侧板001和内侧板002连接形成，但应理解，由单独的一块板形成的侧板也可以实现本发明的目的。
申请人经过深入的研究，发现在相邻的两侧板上在与锁扣结构高度相同的位置设有附加的咬合结构，从而该附加的咬合结构和其余部位的咬合结构一起将相邻的两侧板从上到下连接，能够大大地提高整个可折叠容器的强度。
根据具体的要求，锁扣结构、咬合结构以及附加的咬合结构可具有不同的结构和形状，而不限于附图中所示的结构和形状。
由于相邻两侧板之间的连接强度最弱的地方出现在锁扣结构处，因此，在锁扣结构所在位置增加设置附加咬合结构将极大提高相邻两侧板的连接强度，从而从整体上提高可折叠容器的强度。根据有限元分析实验，相同的可折叠容器由于在锁扣结构处设置咬合结构，比没有在锁扣结构处设置咬合结构的整体强度要提高近1.5～2.5倍，从而在相同容积下，在锁扣结构处设有咬合结构的本发明能够承载更重的货物。例如，在锁扣结构处不设置咬合结构的现有可折叠容器(例如周转箱)仅能够容纳300kg重的货物，而本发明的可折叠容器能够容纳约500kg重的货物。
为了叙述方便，下文中，将侧板面向可折叠容器内部的面称为内侧面，将侧板面向可折叠容器外部的面称为外侧面。
实施例1
如图2所示，本发明的可折叠容器包括：底座1、侧板2、侧板3、侧板4和侧板5。其中，侧板2和侧板4为相对侧板。侧板3和侧板5为相对侧板。侧板2与侧板3和侧板5为相邻侧板。侧板4与侧板3和侧板5为相邻侧板。其中，在两个相邻侧板的连接处设置有咬合结构和锁扣结构。咬合结构用于连接两相邻侧板。锁扣结构用于锁紧两相邻侧板，从而当锁扣结构锁紧时，两相邻侧板相互固定，当锁扣结构打开时，两相邻侧板可以彼此分离。
在本优选实施例中，侧板5上还设有侧门51，但本领域的技术人员可以理解，侧板5上也可以不设置侧门51，这并不影响实现本发明的目的。
在本优选实施例中，侧板由两块板相互连接而形成，例如采用双面热板焊接的工艺制造而成。
如图3所示，侧板2包括外侧板2a和内侧板2b，侧板5包括外侧板5a和内侧板5b。侧板3和侧板4的结构分别与侧板5和侧板2的结构相同。即侧板3包括外侧板3a和内侧板3b，侧板4包括外侧板4a和内侧板4b。其中，同一侧板的外侧板和内侧板通过焊接的工艺焊接在一起。当然，本领域的技术人可以理解，外侧板和内侧板也可以通过其他方式连接在一起。
在本优选实施例中，侧板3和侧板5位于侧板2和侧板4之间。相邻侧板之间的咬合结构由分别设置在两相邻侧板中的一个侧板的内侧板的内侧面上和另一个侧板的内侧板的外侧面上的T字形槽和T字形凸起，以及设置在与锁扣结构相同高度处的附加咬合结构构成，该附加咬合结构(下文将进一步详细说明)与其它咬合结构一起实现了两个相邻侧板之间由下至上的连续的咬合，从而大大增强了两个相邻侧板之间的连接强度。
为了更清楚的理解本发明的目的和精神，以相邻侧板2、5的咬合结构来说明本发明的相邻侧板之间的咬合结构。
如图3所示，相邻侧板2、5之间通过将侧板2的内侧板2b的内侧面2b0连接至侧板5的内侧板5b上而相互连接。其中，侧板2的内侧板2b从其邻近侧板5的一侧向着侧板5一体伸出一凸出部2b0。在该凸出部2b0上设置有T字形槽2b1、T字形凸起2b2以及T字形凸起2b3。相应地，如图5所示，从侧板5的内侧板5b的与侧板2相邻的外侧面上设置有T字形凸起5b1、T字形槽5b2以及T字形槽5b3。当两相邻侧板2、5相互连接时，内侧板2b上的T字形槽2b1、T字形凸起2b2以及T字形凸起2b3分别与内侧板5b上的T字形凸起5b1、T字形槽5b2以及T字形槽5b3相互咬合，从而将侧板2和侧板5连接。其余相邻侧板之间的咬合结构与侧板2和侧板5之间的咬合结构类似。
虽然本优选实施例中的相邻侧板之间的咬合结构为设置在相邻侧板的连接处的T字形槽和T字形凸起，但本领域的技术人员应该知道，该咬合结构也可 是其他形式，比如“燕尾槽”、方形槽等，或其它可相互咬合的结构。而且，咬合结构所包含的槽和凸起的数量不限于图4和5中所示的3个，而是可以根据需要设置适当数量的槽和凸起。
现在通过侧板2和侧板5之间的锁扣结构52来说明本发明相邻侧板之间的锁扣结构。在本优选实施例中，锁扣结构52包括：锁舌6、锁舌驱动装置7、锁舌安装孔2b41、锁舌驱动装置安装孔521和锁舌驱动装置安装凹槽522。锁舌6置于侧板2的锁舌安装孔2b41中，锁舌驱动装置7由把手和推杆构成，其中，把手和推杆分别容纳于安装凹槽522和安装孔521中并相互连接，从而推动把手时，能够带动推杆，并进而驱动锁舌作相应运动，从而实现锁定和解锁，下面将将进一步详细说明。
具体地，如图3～5所示，锁扣结构52位于相邻侧板2、5的连接处。如图5所示，内侧板5b的外侧面在靠近侧板2的位置向着容器外一体伸出一个近似长方体的突出块520。突出块520上设有贯穿其的锁舌驱动装置安装孔521。在侧板5的外侧板5a上设置有凹槽522，凹槽522与孔521连通。凹槽522用于容纳锁舌驱动装置7的把手72。侧板5的外侧板5a上与凹槽522并排还设置有辅助凹槽523，辅助凹槽523用于操作锁舌驱动装置时辅助借力。突出块520的面向外侧板5a的面上)上设置有至少一个附加咬合结构5201。较佳地，突出块520一体地形成于内侧板5b上，且附加咬合结构5201一体地形成于突出块520上。其中，附加咬合结构5201与锁舌安装孔521的垂直距离不小于一定的尺寸，比如为3～5毫米。
在本优选实施例中，附加咬合结构5201为设置在突出块520面向外侧板5a的面上)的两个凸起和一个凹槽。但本领域的技术人员可以理解，其他形式的附加咬合结构也可适用于本发明。另外，凹槽和凸起的数量也可以根据可折叠容器的尺寸设置。
相应地，如图4所示，侧板2b的凸出部2b0上在与锁扣结构高度相同的位置处设置有近似长方体形状的缺口2b4，该缺口2b4与侧板5上的突出块520对应。在缺口2b4所在的位置设置有锁舌安装孔2b41，用于容纳锁舌6。在缺口2b4的外侧还设置有至少一个附加咬合结构2b42，用来与侧板5上的附加咬合结构5201配合。在本优选实施例中，附加咬合结构2b42为两个凹槽和一个凸起。但本领域的技术人员可以理解，该附加咬合结构也可以为其他形式，只要 和侧板5上的附加咬合结构相对应即可。
在本优选实施例中，锁舌和锁舌驱动装置如下设置。但应理解，其它形式的锁舌驱动装置也可以适用于本发明。
如图6所示，本优选实施例的锁舌6的主体两侧具有弹性卡扣62。该弹性卡扣62用于将锁舌装配到锁舌安装孔2b41中，在侧板上设有与弹性卡扣62相配合的孔或槽(图未示)。锁舌6的尾部为弹片61，弹片61具有弹性，用于当锁舌没有受到锁舌驱动装置的力的作用时锁舌6的复位。锁舌6的前端为锁闩63，锁闩63的一侧具有导向斜面64。导向斜面64上设有凹槽65，凹槽65可以容纳普通的一字螺丝刀头，从而可以借助凹槽65将锁舌6从锁舌安装孔2b41中拆出。
如图7～9所示，锁舌驱动装置7包括推杆71和把手72。推杆71的主体大致为长方体，其尾端711具有和把手72连接用的凹槽712。推杆71的尾端711两侧具有凹槽713，凹槽713的上面具有小的限位块714。
图7和图8为把手72的详细结构。把手72的正面具有槽720，用于操作把手时扣手用。把手72的背部具有连接推杆71的尾部711的凹槽721。凹槽721中设置有凸台722和凸台723，用于分别与推杆71的凹槽712和凹槽713配合。凸台723中部设置有槽724。将推杆71和把手72安装到位后，限位块714进入到槽724中，从而防止推杆71轻易从把手72中脱出，如图9所示。
图10～12为组装状态时，附加咬合结构及锁扣机构的连接及解锁过程的剖面图。当侧板2和侧板5相互连接时，咬合结构2b1、2b2、2b3和咬合结构5b1、5b2、5b3互相咬合，同时设在锁扣结构位置的附加咬合结构2b41和附加咬合结构5201互相咬合。这样，相邻侧板2、5之间从上到下都有咬合，因此，侧板2和侧板5连接处所能承受的载荷如图15所示，从而保证了侧板2和侧板5的连接处的强度。
如图10所示，当处于锁定状态时，由于锁舌6的弹片61的弹力作用，锁舌6的锁闩63从锁舌安装孔2b41中伸入到锁扣结构安装孔521中。由于受到锁舌6的推动，推杆72处于后缩的状态，从而侧板2和侧板5被锁定。此时附加咬合结构5201被夹在锁舌6和附加咬合结构2b42之间，这样，除非锁舌6从推杆安装孔521中退出(即解锁)或者其中之一的零件被损坏，附加咬合结构5201和附加咬合结构2b42不会轻易脱出分离，从而保证了此附加咬合结构 的强度。
如图11所示，当需要解锁时，通过孔523借力，将把手72向前推动，通过推杆5推动锁舌6缩回锁舌安装孔2b41中，使锁舌6的锁闩63从推杆安装孔521内脱出。此时，如图11所示，向内推动侧板5即可解除锁定。本领域的技术人员可以理解，锁舌的驱动机构不限于本优选实施例所例举的直接移动的推杆形式，还可以为其他形式，比如可以利用旋转形式的把手再经由推杆推动或直接推动锁舌。
实施例2
如图13～17所示，本优选实施例与实施例1的不同之处在于锁定机构和位于锁定机构相同高度处的附加咬合结构。
在本优选实施例中，可折叠容器包括：底座1、侧板20、侧板30、侧板40和侧板50。其中，侧板20和侧板40为相对侧板。侧板30和侧板50为相对侧板。侧板20与侧板30和侧板50为相邻侧板。侧板40与侧板30和侧板50为相邻侧板。其中，在两个相邻侧板的连接处设置有咬合结构和锁扣结构。咬合结构用于连接两相邻侧板。锁扣结构用于锁紧两相邻侧板，从而当锁扣结构锁紧时，两相邻侧板相互固定，当锁扣结构打开时，两相邻侧板可以彼此分离。
与优选实施例1相同，在本优选实施例中，侧板20包括外侧板20a和内侧板20b，侧板50包括外侧板50a和内侧板50b。侧板30和侧板40的结构分别与侧板50和侧板20的结构相同。即侧板30包括外侧板30a和内侧板30b，侧板40包括外侧板40a和内侧板40b。其中，同一侧板的外侧板和内侧板通过焊接的工艺焊接在一起。当然，本领域的技术人可以理解，外侧板和内侧板也可以通过其他方式连接在一起。
现在通过侧板20和侧板50之间的锁扣结构60来说明本发明相邻侧板之间的锁扣结构。在本优选实施例中，锁扣结构包括：锁舌、锁舌驱动装置、锁舌安装孔以及锁舌驱动装置安装孔。与优选实施例1不同，在本优选实施例中，锁舌和锁舌驱动装置位于同一侧板上，且锁舌驱动装置仅仅包括把手。
如图13～17所示，锁扣结构60位于相邻侧板20、50的连接处。在内侧板20b的内侧面上向着侧板50一体伸出一第一突出块20b0，在该第一突出块20b0上设有锁舌接纳孔20b1，用于在侧板20和侧板50相互锁定时容纳锁舌602。在第一突出块20b0的面向容器内部的面上设有至少一个附加咬合结构20b2。在 本优选实施例中，附加咬合结构20b2为凸起和凹槽。但本领域的技术可以理解，该附加咬合结构也可以为其它形式。
在内侧板50b的与侧板20相邻的连接侧面上设置有锁孔50b1。锁孔50b1用于容纳锁舌602，并在锁定时供锁舌穿过其以伸入锁舌接纳孔20b1。在内侧板50b上在靠近锁孔50b1的位置处设置有附加咬合结构50b2，用于与附加咬合结构20b2配合连接。在本优选实施例中，附加咬合结构50b2为在内侧板50b上朝向外侧板50a20一体伸出的第二突出块，在该第二突出块上设有凹槽和凸起，该凹槽和凸起分别与附加咬合结构20b2上的凸起和凹槽配合，从而在两个相邻侧板连接时(组装好)，两个相邻侧板上的附加咬合结构相互咬合。但本领域的技术可以理解，该附加咬合结构也可以为其它形式。
侧板50的外侧面上设置有把手安装孔501，用于容纳把手601。把手安装孔501与孔50b1垂直并连通。
在本优选实施例中，锁舌602安装于侧板50的锁孔50b1中。把手601设有一个扣合部6011。相应地锁舌602上设有扣合孔6021。把手601通过扣合部6011连接在锁舌602上的扣合孔6021中，从而与锁舌602连接。组装好后，锁舌602位于锁孔50b1中，把手601位于把手安装孔501中。把手安装孔501的尺寸大于把手601的尺寸。从而把手601可以在把手安装孔501中移动。
如图14所示，锁舌602的尾部具有弹片6022。当锁舌602装入锁孔50b1中时，在弹片6022的弹力作用下，锁舌602处于向前伸出的状态，从而在锁定状态下，锁舌602伸入到位于侧板20上的锁舌接纳孔20b1中，从而将侧板20和侧板50锁定。处于锁定状态时，侧板20的附加咬合结构20b2与侧板50的附加咬合结构50b2互相咬合。锁舌602伸出的舌部6023被侧板20b上的附加咬合结构20b2所限制，侧板20b无法向内侧(图12、14所示右侧)移动。同时，当侧板20b受到内侧(图12、14所示下侧)的作用力时，附加咬合结构20b2和50b2相应承担了一部分作用力。因此，附加咬合结构从上到下连续排列，侧板20和侧板50连接处所能承受的载荷如图16所示，从而保证了侧板20和侧板50的连接处的强度。
需要解锁时，后退把手601使得锁舌602的舌部6023退回到锁孔50b1中，从而脱离附加咬合结构20b2的限制，再向内侧移动侧板50即可解锁。
需要指出的是，为了便于以上的描述，这里引入了术语“外侧板”和“内 侧板”以及“外侧面”和“内侧面”，但是这不应理解为对本发明范围的限制。
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。
