本发明涉及大型容器的可折叠容器壁的锁定系统。 背景技术
一种容器， 它包含有可折叠并可拆卸的侧板以及和侧板连接的底座， 这种 连接多为铰链形式。 可选的在侧板上具有一个小门， 它被用来进入容器内部而 不需打开或者拆卸整面侧板， 这种容器为大家所熟知， 特别是用于转运与储藏 各种物体 (比如整件物体和散装材料)的大型容器。这种空的折叠式容器的侧板可 以折叠， 这样， 容器高度大大变矮， 占据空间也更加缩减， 利于运回重新装货， 一面或者多面侧板或者损坏的侧板均可以拆下换新的。 而且， 侧板上带有小门 的容器， 更方便人们拿取容器底部的货物。
容器的侧板通常是在下端使用铰链铰接到容器底座上， 侧板的小门也多由 铰链和侧板相连接。 侧板通过绕铰链转动， 实现其直立和放倒的变化， 侧板上 的小门也同样依靠绕铰链旋转来实现打开和闭合。 在使用容器的时候， 侧板就 需要保持直立， 小门也需要保持关闭， 这就要依靠一个锁定装置将它们保持在 需要的状态。
为了实现以上目的， 相邻的侧板间都设置有咬合结构， 也就是说侧板间的 相互咬合连接提供了部分的锁定， 如果将相邻的侧板再进行锁定， 就可以满足 使用中每个侧板都要保持的直立要求。 通常的做法是在一块侧板上做一凹槽， 凹槽靠近该侧板边缘并接近相邻的侧板， 锁闩放置于凹槽内， 相邻的侧板上具 有可以容纳锁闩端部的凹坑， 通过锁闩进入和离开凹坑来达到锁定或解锁侧板 间的锁合。
专利 US4923079公开了一种很典型的推拉式的锁定系统。 它在侧板上有一 个凹槽， 相邻的侧板上有一个凹坑， 锁闩通过凹槽进入凹坑， 另外还设置有弹 簧装置来使锁闩复位并保持在锁定状态。 当人们推动或拉动锁闩， 使其脱离凹 坑， 锁定解除， 侧板即可进行折叠。 同样， 小门也适用这种锁定系统。
上述专利是实现侧板间相互锁定的十分简便的方法， 但这种方案操作锁闩 时比较费力。 专利 WO2005102852披露了一种典型的旋转式的锁定系统。 它主要特征在 于其锁闩具有一个垂直于侧板的旋转枢轴， 当锁闩旋转时其端部通过侧板上的 凹槽进入或脱离相邻侧板上的凹坑， 锁闩上还具有一个弹性叶片来驱动其复位 并保持锁定状态。
该专利有效降低了解锁时所需要的作用力， 但它在装配上有一定复杂度， 且提供的锁定强度有限。 发明内容

所述的适用大型容器的锁定系统， 其进一步的特点是， 把手收纳在第一部 件中。
所述的适用大型容器的锁定系统， 其进一步的特点是， 该第一部件为该大 型容器的第一侧板， 该第二部件为该第一侧板相邻的该大型容器的第二侧板， 第一侧板和第二侧板均可折叠地设置在一基座上， 所述枢轴垂直于该基座。
所述的适用大型容器的锁定系统， 其进一步的特点是， 把手由第一部件的 凹部接收， 把手的两相对侧各通过枢轴连接凹部的两相对侧， 把手在该两相对 侧上各具有该凸销， 锁闩具有舌部和自舌部的两侧延伸出的控制臂， 在各控制 臂上形成有所述凹面轮廓， 锁闩的控制臂穿过第一部件的孔进入到该凹部， 并 通过凹面轮廓与相应的凸销接触配合， 锁闩的舌部伸出第一部件插入到第二部 件的凹槽中， 以锁定第一部件和第二部件。
所述的适用大型容器的锁定系统， 其进一步的特点是， 舌部和第一部件的 与第二部件相邻的侧部之间设置有弹簧， 该弹簧保持该舌部插入在第二部件的 凹槽中。

所述的适用大型容器的锁定系统， 其进一步的特点是， 所述第一部件为该 大型容器的侧板上的门， 该第二部件为该侧板。
把手通过枢轴设置在第一部件上， 可朝第一部件的外侧翻转， 外翻式操作 更容易为操作者接收， 并且把手在偏离该枢轴的部位具有凸销， 对应凸销， 锁 闩具有凹面轮廓， 该凸销和该凹面轮廓接触配合， 以使把手和锁闩构成一杠杆 系统， 扳动把手， 把手的施力部位和凸销和该凹面轮廓接触配合处有一定距离， 因此通过杠杆式的把手来驱动锁闩， 操作省力， 并且仅仅需要将凸销装配到凹 面轮廓中， 就可以进行传动， 因此安装过程也非常简单。 附图说明
图 1是可折叠容器的立体图。
图 2是锁定系统处于锁定状态的示意图。
图 3是锁定系统解锁操作的原理图。
图 4是锁定系统的分解视图。 具体实施方式
如图 1所示， 可折叠容器， 例如货箱包括具有矩形平板结构的基座 8， 其中 可折叠侧板 1、 2、 3、 4通过铰链组件联接在基座 8的边缘。 侧板 1、 2、 3、 4 处于竖立位置时， 侧板 1、 2、 3、 4通过后述的锁定系统 6而结合联接， 进而保 持在直立状态。 可选地， 侧板 4上设置有一小门 5， 小门 5和侧板 4之间也可通 过后述的锁定系统 6来结合连接， 以保持小门处于关闭状态。
如图 2所示， 锁定系统安装在侧板 4相邻侧板 1的部位， 包括一个把手 9 和锁闩 10。
在图 2中侧板 4的上侧为外侧， 下侧为内侧， 把手 9从外侧看， 其本体成 方形的平板状， 从图 2中的前侧看， 其上、 下两侧的侧壁为三角形的平板状， 图中没有示出， 但是可以理解的是， 从图 2的左侧看， 把手的左侧壁为方形的 平板状。 如图 2所示， 把手 9收纳在侧板 4中， 因此不占用额外空间。
如图 4所示，锁闩 10具有舌部 15以及自舌部 15的两侧伸出的控制臂 151， 各控制臂 151上有长条形的导向凹槽 17以及凹面轮廓 12。对应控制臂 151上的 导向凹槽 17， 在侧板 4的凹部 40的两相对侧壁上具有凸起 16。对应控制臂 151 上的凹面轮廓 12， 在把手 9的上、 下侧壁上各有凸销 1 1。
如图 2和图 3所示， 凸销 1 1和凹面轮廓 12可接触配合以形成滑动副， 并 可进行传动， 因此把手 9和锁闩 10构成杠杆系统， 该把手 9即为以枢轴 13(如 图 4所示)为支点的曲柄且为主动件， 输出转动， 该锁闩 10为从动件， 输出直线 运动， 把手 9的施力部位至该支点的距离大于所述滑动副至该支点的距离。
继续参照图 4， 把手 9的上、 下侧壁上还有枢轴 13， 相应地， 凹部 40的上、 下侧壁上有销孔 20。枢轴 13插入在销孔 20中， 因此把手 9就以枢轴 13为轴线 可相对侧板 4向外翻转。 同时参照图 1， 优选地， 枢轴 13是垂直于基座 8的。
如图 2和图 3所示， 锁闩 9的舌部 15伸入到侧板 1的凹槽 14中， 这时侧 板 1， 4是相互锁定的状态。 由于把手 9具有枢轴 13， 当掰动把手 9绕枢轴 13 旋转时， 把手 9上的凸销 1 1和锁闩 10上的凹面轮廓 12的左端相接触并带动锁 闩 10向左移动， 使其舌部 15脱离侧板 1的凹槽 14， 从而解除侧板 1， 4间的相 互锁定。
如图 3所示，当锁定系统处于解锁状态时，把手 9被掰到一个设定的角度 (例 如 35度左右）， 这时候侧板 4上的限位面 18， 19和把手 9的外侧面、 左侧面为 面面接触， 相依靠， 把手 9无法再向外转动。 同时参照图 1， 当人们抓住把手 9 向内折叠侧板 4时， 把手 9将承受部分侧板的自重力。 而侧板 4的限位面 18， 19和把手 9的旋转枢轴 13有效分担了这些自重力， 不至于把手轻易损坏。
侧板上的两个凸起 16， 当锁闩 10从外面插入到侧板 4中， 锁闩上的导向凹 槽 17恰好的容纳了凸起 16， 这样， 锁闩就不会因为重力、 一般的抽拔力或锁闩 10 自身的复位力而从侧板 4中脱出。
如图 4所示， 装配时， 锁闩 10从侧板 3的侧面首先插入到侧板 4中， 凸起 16将其限定而不能脱出， 然后从正面将把手 9装配到侧板 4中， 使旋转枢轴 13 进入到侧板的孔 20中； 拆卸时反顺序操作即可。
锁闩 10具有弹簧， 例如两个弹性的叶片 21， 其介于侧板 4的侧面和舌部 15之间， 用于锁闩 10的复位并使其保持在锁定状态， 即舌部 15处于伸出的状 态。 当侧板 4从折叠状态改变到使用状态时， 旋转到一定角度时候， 锁闩 10的 舌部 15将和侧板 1相碰撞， 使锁闩向侧板 4内部移动。 锁闩 10的凹面轮廓 12 是一个长形的轮廓， 所以当其向内移动时并不会带动把手 9转动。
如图 3所示，把手 9的施力部位 (右侧边缘)相对于枢轴 13和凸销 1 1有一定 的距离， 该距离增加了力臂， 因此翻转把手 9的过程通过杠杆原理可知， 非常 省力。
