Description

容器盖子锁定机构及容器 技术领域
本发明涉及容器， 具体涉及容器盖子锁定到容器箱体的锁定机构。 背景技术
一般的， 大型容器都具有四个侧板以及一个底， 用于运输液体或散货的大 型容器往往还具有一个盖子， 用来保护内部装载的货物。 盖子的四周有一圈护 边， 它们靠近容器四个侧板的外侧， 当容器内部的货物对侧板产生大的作用力 时， 盖子的护边就可以一定程度上保护侧板不至于变形过大。 另外的， 当容器 内的液体或散货向上波动时， 盖子能很好的限制盛放它们的衬袋的起伏， 从而 也保护了衬袋不被损坏。 这样以来就要求盖子在使用时能够可靠的和箱体相连 接。 另外的， 这些大型容器的四个侧板大多可以依次折叠， 可以减少容器不使 用时的所占用的储存空间， 以降低产品的周转、 仓储成本。 而且， 当盖子盖到 折叠好的容器上时， 其上的和箱体连接的机构也应该尽量避免累加很高的高度。
现有的产品中， 有一种箱体和盖子的锁定方式， 它具有一个带把手的横闩， 在盖子的上部边缘有一个凹坑容纳该横闩。 凹坑的侧部有一个孔， 可以使横闩 通过并伸入到容器侧板的凹槽中。 当盖子在使用状态时， 横闩限制盖子从箱体 上向上移动， 同时， 横闩上的手柄被凹坑中的凸筋限制了横向移动， 这样它就 能可靠的被锁定了。 这种设计虽然满足了基本的盖子和箱体的连接， 但是由于 横闩没有复位结构， 当盖子放置到箱体上且横闩处于伸出状态时， 就会使得横 闩直接被挤压在箱体的侧板上从而可能被损坏。 发明内容
本发明的目的是提供一种不会被轻易损坏， 且盖子的开启和闭合都非常方 便的容器盖子锁定机构。
为实现上述目的， 本发明提供了一种容器盖子锁定机构， 所述容器具有底座、 侧板、 以及盖子， 其特征在于：

上述优选实施例中， 优选地， 所述手柄的侧面还具有一个凹槽。
本发明的另一优选实施例中，所述锁定构件为一锁定件，所述复位构件为扭簧， 所述导向构件包括位于盖子上的凹槽和位于侧板上的配合结构； 其中， 所述锁定件 可安装在所述配合结构中并可进入或离开所述凹槽以实现盖子的关闭或开启。
优选地， 所述锁定件具有旋转销、 承载销、 和两个限位销， 所述限位销之一 上还具有一个凸台， 且所述扭簧设置在所述锁定件上；
所述配合结构包括位于侧板上部两侧上的凹坑， 位于所述凹坑中的圆孔、 异形通孔和限位孔， 异形通孔还具有异形轮廓弧面； 其中
当锁定件安装到侧板上时， 所述旋转销***所述圆孔中， 所述两个限位销 分别***异形通孔和限位孔中， 从而使所述锁定件保持在所述配合构件上； 且 当盖子在侧板上滑动时， 所述承载销可进入或脱离凹槽以实现盖子的锁定 和移除。
优选地， 所述凹槽位于盖子的下表面的左右两侧， 凹槽的外侧为一个斜坡， 内部为一个凹坑， 凹坑的下部具有弧形轮廓。
本发明还提供了一种容器， 包括底座、 侧板、 以及盖子， 其中， 所述容器还包 括上面实施例中所述的容器盖子锁定机构。
本发明的盖子锁定机构中，锁定机构位于盖子的边缘或侧板的上部且结构小巧 紧凑， 因此有利于减少箱体折叠后盖子的累加高度， 降低运输和仓储成本。 此 夕卜， 锁定机构还具有复位构件和导向构件， 使得当盖子放在容器的箱体上时， 不 管其是处于闭合状态还是开启状态， 锁定机构都不会被轻易损坏， 而且盖子的 开启和闭合都非常方便。 附图说明

图 3为锁定件 8 的立体图， 其上还具有一个扭簧 9。 锁定件 8具有旋转销
83， 承载销 81， 限位销 82和 84， 限位销 84上还具有一个凸台 841。 该凸台 841 的作用将会在下面描述。 扭簧 9则安装在旋转销 83上。
图 4a-4b为侧板 6的局部侧向视图， 侧板 6的上部两侧具有一个凹坑 61， 凹坑 61上还有圆孔 63和异形通孔 64，异形通孔 64还具有一个特殊的轮廓弧面 641。 挡边 65在其左侧， 当锁定件 8安装到侧板 6上时， 旋转销 83首先***到 圆孔 63中一部分， 限位销 84上的凸台 841对准弧面 641， 这时候锁定件 8才可 以完全装入。 锁定件 8装入后， 限位销 82位于限位孔 62中。 由于扭簧 9会对 锁定件 8—直保持逆时针向的一个扭矩， 使得锁定件 8保持和挡边 65相贴合。 此时， 由于凸台 841偏离弧面 641， 使得锁定件无法脱出， 也仅在限位销 84上 的凸台 841 对准弧面 641 时才可以脱出。 此外， 虽然未示出， 但是， 与侧板 6 相对的侧板 4上也设有相应的结构。
图 5示出盖子 1从正上方安放在容器箱体上时， 锁定件 8如何进入凹槽 12 的过程。 斜坡 122首先和锁定件 8的承载销 81接触， 由于斜坡 122的压力， 会 迫使锁定件 8 以其旋转销 83为轴心顺时针旋转一定角度， 使得承载销 81避开 了凹槽 12下移的位置。 当盖子 1 向下放置到位时， 承载销 81正好对应着凹槽 12的凹坑 121， 由于扭簧 9的复位作用， 使得锁定件 8以其旋转销 83为轴心逆 时针旋转，从而使得承载销 81进入到凹坑 121中， 由此限制了盖子 1 向上移动。
打开盖子时， 当盖子 1 被从右侧即侧板 4 的方向打开一定距离时， 盖子 1 也就相当于以其和侧板 6 的右上部接触的地方为支点旋转了一个角度。 此时继 续向前推动盖子 1， 锁定件 8的承载销 81从盖子 1的凹槽 12中脱出， 从而实现 盖子 1的开启。
图 6-12示出了根据本发明的大型容器盖子锁定机构的第二实施例的结构示 意图。如图 6所示， 盖子锁定机构包括设置在盖子的边缘的凹坑 14、左手柄 12、 右手柄 10以及弹簧 1 1。如图 7-7b所更清楚示出的，凹坑 14的侧壁上有方孔 141 (或多边形孔 141 ) ， 凹坑 14的另一边有滑轨 143， 滑轨 143的横截面为工字 型， 但也可以是诸如横截面为 T型的其他类型滑轨。 滑轨 143和方孔 141之间 有一处 u形的凸筋 142用来容纳弹簧 1 1。
图 8a-8b示出盖子锁定机构的右手柄 10， 左手柄 12结构和作用方式与右手 柄相同， 在此不再详述。 如图 8a所示， 右手柄 10的一端有一个锁舌 103， 另一 端设有滑槽 101， 锁舌 103的背面为一个坡面 1031， 手柄 10的背面有长槽 102， 长槽 102的侧壁上具有一个小的凸销 1021。手柄 10的侧面还具有一个凹槽 104， 以方便人们抓握， 如图 8b所更清楚示出的。
图 9和 10显示了盖子 1放置到箱体上且未完全闭合时的状态， 其中， 图 10 为图 9中部位 D的放大图。 如图 10所示， 当手柄 10放置在盖子 1的凹坑 14中 时， 滑轨 143和滑槽 101相扣合， 锁舌 103穿过方孔 141。 弹簧 1 1被放置在右 手柄 10的长槽 102和盖子的凸筋 142所形成的空腔内， 凸销 1021辅助的来保 持装配时弹簧 1 1不至于轻易从右手柄 10的长槽 102 内脱出。 这样， 由于弹簧 的复位作用， 手柄 10的锁舌 103会始终趋于伸出的状态。
当进一步向下按压盖子 1时， 如图 1 1 -12所示， 盖子 1承受压力， 由于锁舌 103的坡面 1031的导向作用， 右手柄 10会向左移动， 使其锁舌 103能够越过侧 板 4的侧部， 继续施加压力到盖子 1上时， 盖子就会和箱体贴合， 此时锁舌 103 可以恰好的对应到侧板 4上侧面的凹坑 41， 弹簧 1 1驱使锁舌 103进入到凹坑 41中， 从而将盖子 1和侧板相锁定。
当需要打开盖子 1时， 仅需要使手柄 10沿滑轨移动， 使锁舌 103推出侧板 上的凹坑 41然后向上提起盖子 1就可实现盖子的开启。 需要指出的是， 可根据需要在盖子和侧板上设置适当数量的盖子锁定机构。 上述各实施例中， 锁定机构位于盖子的边缘或侧板的上部且结构小巧紧凑， 因此有利于减少箱体折叠后盖子的累加高度， 降低运输和仓储成本。 此外， 锁 定机构还具有复位构件和导向构件， 使得当盖子放在容器的箱体上时， 不管其 是处于闭合状态还是开启状态， 锁定机构都不会被轻易损坏， 而且盖子的开启 和闭合都非常方便。
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。
