在本发明中， 该前框 45可分上下两部分， 上部包括上左前框 451 (第一 门框） 、 上右前框 452 (第二门框） ， 下部包括下左前框 453 (第一门框） 、 下右前框 454 (第二门框） ， 上下部的左右前框通过锁具 50连接锁止， 且前 框与左、 右端框通过铰链连接实现组对、 折叠功能。 该后框 42为两段式样， 通过铰链进行连接可折叠， 保证台车空 时折叠保存以便占用最小仓储空间。 该左端框 43为可折叠设计， 通过铰链与后框 42、 上 /下左前框 451、 453实现 连接； 另外左端框 43上还可设有防碰块， 可有效防止上 /下左前框 451、 453 折叠时对左端框 43撞击产生损害。该右端框 44也为可折叠设计，通过铰链与 后框 42、上 /下右前框 452、 454实现连接。该底架分为左右独立的左右底架两 部分， 分别与左右端框、 后框连接构成台车的框架主体。 在台车前框 45的上 / 下部相邻两个门框之间设置有台车锁具 50 (如图 2中 B部分所示） ， 如上左 前框 451和上右前框 452之间、 下左前框 453和下右前框 454之间， 该锁具 50由旋转锁 51、锁座板 52配合实现门框的锁紧。并且， 为了更好的配合锁具 实现锁紧功能，在该上左前框 451和上右前框 452之间、下左前框 453和下右 前框 454之间还通过啮合装置 60 (如图 2中 A部分所示）配合， 分别在上下 两端处使上左前框 451和上右前框 452、 以及下左前框 453和下右前框 454更 顺畅快捷的实现啮合锁紧功能。
如图 3A、 3B所示， 在本发明中， 该啮合装置 60通过安装孔 63 (如图 3B 所示） 安装在上右前框 452的门框立柱 4521上。 该上左前框 451的门框立柱 4511可为一带圆弧压型角 R的板折弯件（或其他成品型材） ， 其 R角设计可 满足良好的啮合功能。 相应的， 该啮合装置 60与该上左前框 451的门框立柱 4511啮合的侧面上设置有与该门框立柱 4511形状适配的啮合导向槽 62。
如图 3C所示，示出了应用在台车上的本发明的锁具的结构。在本发明中， 该旋转锁 51设置于该上、 下左前框 451、 453上。 该旋转锁 51主要包括有锁 架 511，其设置于该上左前框 451的预定位置上， 并具有一安装孔 5111 (如图 6A所示） ； 锁轴 512， 通过该安装孔 5111活动安装于所述锁架 511上， 且其 一端端部 （朝向门框内侧设置） 套装连接于一定位卡圈中， 从而将锁轴 512 活动固定在锁架 511上； 手柄 513， 其一端与该锁轴 512另一端部（朝向门框 外侧设置）连接， 并可在外力作用下带动该锁轴 512在第一旋转位置 5131和 第二旋转位置 5132之间旋转。 该锁座板 52设置于该上、 下右前框 452、 454 上， 其上具有与该锁轴 512适配的第一通孔 521 (如图 8C所示）和与该手柄 513适配的第二通孔 522， 其设置于该第一通孔 521—侧且与该第一通孔 521 连通， 且该锁座板 52—端设置有一手柄挡板 523， 与该第二通孔 522相对设 置于该第一通孔 521的另一侧。 在锁紧时， 该锁座板 52通过第一通孔 521、 第二通孔 522嵌位在锁架 511上， 此时旋转手柄 513从第一旋转位置 5131旋 转至第二旋转位置 5132， 并通过该手柄挡板 523阻挡该手柄 513继续转动而 将该锁具锁紧。
图 4A、 4B分别为该手柄 513处于第一旋转位置 5131时旋转锁正面、 背 面的立体结构示意图， 图 4C、 图 4D分别为该旋转锁的正视图和俯视图。 在 该锁架内侧表面上，邻近该定位卡圈 516外圆周位置还设置有一阻挡块 5116， 该定位卡圈 516的外圆周的一预定位置处向外延伸有一限位块 5161。如图 4A 所示，该第一旋转位置 5131为该手柄 513转动至与该锁座板 52上的第二通孔 522重合且该限位块 5161与该阻挡块 5116相接触的位置， 该第二旋转位置 5132为该手柄 513转动至与该手柄挡块 523接触的位置 （如图 3C所示） 。
如图 5所示，详细示出了该锁轴 512安装在该锁架 511上的结构。结合图 6A示出的锁架 511立体结构和图 6B、 6C示出的锁轴 512的结构， 可清晰看 出， 该锁架 511具有一与锁轴 512适配的安装孔 5111， 该锁轴 512中间部分 的外圆周形成一相对其两端的凸起，其一端还具有一与该手柄 513适配的、键 槽 5123。在安装时， 可先将该手柄 513—端通过该键槽 5123与该锁轴 512连 接， 如图 6D所示， 然后将该锁轴的一端通过该锁架 511上的安装孔 5111并 套装入该定位卡圈 516中， 然后焊接该定位卡圈 516和该锁轴 512， 实现锁轴 512与锁架 511的活动安装。在该手柄 513旋转时， 可通过锁轴 512的旋转带 动定位卡圈 516的旋转，使该限位块 5161与该阻挡块 5116互相接触。通过该 P艮位块 5161与该阻挡块 5116的配合使用，在锁具开启时候可有效防止旋转过 位实现快速开启。 并且， 如图 4A所示， 该锁架 511可为一板折弯件， 其三面 折起形成第一折弯边 5115， 另一面开放， 形成与锁座板 52适配的安装空间； 或者， 如图 6A所示， 仅有两面折起形成该第一折弯边 5115。
如图 7A、 7B所示， 示出了该手柄 513旋转至第二旋转位置 5132时的结 构。 当手柄 513由如图 4A所示的第一旋转位置 5131逆时针旋转至第二旋转 位置 5132时，该手柄挡块 523阻挡住该手柄 513的继续转动，此时门框锁紧。 反之， 在第一旋转位置 5131时， 门框可打开。 如图 8A、 8B所示， 示出了本发明的锁座板 52的正面和背面的结构。 该 锁座板 52安装在上、下右前框 452、 454上，并具有相互连通的第一通孔 521、 第二通孔 522， 其一端设置有一手柄挡板 523。 如图 8C所示， 该锁座板 52的 一对侧边进一步折弯形成第二折弯边 525，适配安装于该锁架 511上的安装空 间内。 如图 8D所示， 该手柄挡板 523为 L形结构， 其包括一外侧挡板 5231 和安装板 5232， 该手柄挡板 523通过锁座板 52前端的一切口 526安装， 该外 侧挡板 5231垂直于该锁座板 52向外延伸， 该安装板 5232紧贴该锁座板 52 背面安装固定。 较佳的， 该外侧挡板 5231上设置第三通孔 5233， 相对应的， 在该手柄 313另一端上设置有第四通孔 5133 (如图 4A所示） ， 在该手柄 513 旋转至第二旋转位置 5132时， 该第三通孔 5233与该第四通孔 5133对准， 并 可在该第三通孔 5233和第四通孔 5133中安装有安全锁匙，从而提高箱内货物 仓储运输的安全性。
如上所述，当需要打开台车的门框时，顺时针旋动手柄 513至第一旋转位 置 5131，锁轴 512和与之结合的手柄 513能通过锁座板 52上的第二通孔 522， 即可打开台车门框。 与此同时， 在顺时针旋动手柄 513至第一旋转位置 5131 时， 圆环形定位卡圈 516上的限位块 5161被锁架 511上设置的阻挡块 5116 所阻止， 无法继续顺时针旋转， 可有效防止旋转过位而实现快速开启。 反之， 当逆时针旋转手柄 513至第二旋转位置 5132时候，通过手柄挡板 523的阻挡， 以及在对准的第三通孔 5233和第四通孔 5133中安装假装安全锁匙和通过啮合 装置 40的配合而有效实现门框的锁紧。
当然，本发明还可有其他多种实施例，在不背离本发明精神及其实质的情 况下，熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形，但 这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。 工业应用性
根据本发明的一方面，通过一旋转锁与锁座板的配合，方便快捷的实现对 台车门框的有效锁止，并且，当打开台车门框时，由于阻挡块与限位块的存在， 手柄旋转到第一位置时无法继续同方向旋转， 从而实现快速开启。 同时， 由于 手柄与手柄挡板的通孔配合能用外加的锁具实现对台车前框的进一步锁止，进 一步保证了货物的安全性。
