如图 1所示， 图 1是使用本发明较佳实施例的互相制约式安全型多 抽屉锁定机构的安全拒的总体结构示意图。安全拒 100包括一个柜体 1、 一个限定机构 2、 多个滑动机构 3、 一个锁固机构 4及多个抽屉 5。 该限 定机构 2、 滑动机构 3及锁固机构 4均固设于拒体内， 且每个抽屉 5 固 设于一滑动机构 3。 该拒体 1 包括一安装支架 11 , 该安装支架 11为一阶 梯形支架。 在本实施例中， 该安装支架 11是一阶梯形板状体， 但本发明 不以此为限， 该安装支架 11也可是阶梯形框架结构。 该安装支架 11可 以是独立于拒体 1的元件， 其固定在拒体 1侧板上。该安装支架 11也可
以由柜体 1本身侧板的一部分来实现。该安装支架 11 包括分别位亍阶梯 两层的第一安装层 111及第二安装层 112 , 该第一安装层 111 与该第二 安装层 112之间具有一定距离落差。
限定机构 2固设于该安装支架 11的第一安装层 111上，且限定结构 2不超出第二安装层 112。 该限定机构 2包括若干滑块 21， 该若千滑块 21沿第一方向（本实施例中为垂直方向）可滑动地并列设置在安装支架 11的第一安装层 111上，且该若干滑块 21的厚度不超出第一安装层 111 和第二安装层 112之间的距离。 请一并参阅图 2。 本实施例中， 每一滑 块 21包括近似梯形的一基板 211及沿基板 211两相对的平行边垂直延伸 的第一侧板 212与第二侧板 213 , 第一侧板 212和第二侧板 213的两端 分别由第三侧板 214和第四侧板 215相连接。 该第三侧板 214及第四侧 板 215在第一侧板 212和第二侧板 213之间形成平滑过渡的弧形斜面。 基板 211上平行于第一测板 212开设至少一长条状腰形装配孔 216, 本 实施例中， 为两个长条状腰状装配孔 216 , 但本发明不以此数量为限。 可以理解， 该滑块 21 也可一块状体， 例如， 仅包括基板， 其具有四个 侧面， 分别与第一侧板 212、 第二侧板 213、 第三侧板 214及第四侧板 215的外表面形态相同即可， 在此不再赘述。
请一并参阅图 9 ,每一滑块 21的长条状腰形装配孔 216均与一限位 螺钉 217配合， 以将滑块 21可沿长条状腰形装配孔 216滑动地固定于 安装支架 11的第一安装层 111上。 在所有抽屉 5均为关闭时， 即所有滑 动机构 3 均处于关闭状态时， 每相邻两个滑块 21 通过其第三侧板 214 与第四侧板 215形成的平滑接触面平滑相接且于相接处形成一个楔形开 口。
请一并参阅图 1、 图 3及图 10， 多个滑动机构 3平行地固设于该安 装支架 11 的第二安装层 112上， 且该多个滑动机构 3 靠近第一安装层 111的一端与限定机构 2叠加设置。 每一滑动机构 3包括一轨道 31、 一
滑轨 32及一限位块 33。该轨道 31沿第二方向（本实施例中为水平方向） 设置于安装支架 11的第二安装层 112上。 本发明中， 该第二方向与第一 方向不受限于水平、 垂直方向， 二者之间具有一定角度即可。 该轨道 31 包括靠近第一安装层 111的第一端及与第一端相对的第二端， 该第一端 与限定机构 2 叠加设置， 且对应于 相邻滑块 21 之间的连接处。 该滑 轨 32可滑动地设于轨道 31 内， 限位块 33可滑动地设于轨道 31的第一 端处， 且限位块 33 穿过轨道 31伸至相邻两个滑块 21相接处的楔形开 口。 滑轨 32从轨道 31 第一端向第二端滑动时， 带动限位块 33滑动， 同时限位块 33从对应的相邻两个滑块 21相接处的楔形开口滑入该相邻 两个滑块 21之间， 使该相邻两个滑块 21 中位于上方的滑块 21 向上移 动。
. 具体地， 请参阅图 3。 该轨道 31 包括底板 310及沿底板 310相对两 边垂直延伸的两侧壁 311， 该两侧壁 311相对弯折以与底板 310形成轨 道 31的外框。 请一并参阅图 4， 该轨道 31第一端的底板 310通过一固 定元件比如铆钉或螺钉等方式固定于安装支架 1 1的第二安装层 112上， 在本实施例中， 固定元件为铆钉， 然， 本发明不以此为限， 也可为卡销 等其他具有同等功能的元件。 邻近轨道 31 第一端处， 该底板 310 内侧 中部设置一弯折滑槽 3101，该弯折滑槽 3101 包括一滑行槽 3102和一卡 ^槽 3103， 该卡止槽 3103在该滑行槽 3102—端弯折而形成。 该轨道 31 内的底板 310上， 与弯折滑槽 3101 并列设有一内轨 312, 在本实施 例中， 该内轨 312为叠加于底板 310设置的板状体， 多个滚珠 3111对应 于该内轨 312的两侧并排设置于两侧壁 31 1上。
请一并参阅图 10 ,该底板 310邻近侧壁 312处对应该弯折滑槽 3101 开设一通槽 3104, 该通槽 3104与滑行槽 3102平行， 且通槽 3104远离 轨道 31第一端的一端止于其对应的两相邻滑块 21相接处。
请再次参阅图 3，滑轨 32包括一底板 320和沿底板 320两侧相对弯
折的侧壁 321。滑轨 32的两侧壁 321上分别设有多个凹槽 321 1， 该多个 凹槽 3211与轨道 31的多个滚珠 3111配合，以在滑轨 32沿轨道 31 内的 内轨 312滑动过程中起到定位作用。 滑轨 32的底板 320上设有固定件 321 , 抽屉 5通过该固定件 321 固定在滑轨 32上。 滑轨 32邻近轨道 31 第一端处设一弯折状卡口 322 , 该卡口 322包括平滑相接的卡固端 3221 和敞口释放端 3222。
请一并参阅图 3至图 6, 限位块 33可滑动地设于该轨道 31 内。 如 图 5所示， 限位块 33包括一本体 331及一定位块 332。 该本体 331包括 一第一滑条 3311、 第二滑条 3313 及连接该第一滑条 3311 和第二滑条 3313 的连接部 3312。 该连接部 3312 上设有一竖向长条状腰形装配孔 3314。 该定位块 332凸设于邻近第一滑条 3311的连接部 3312上。 请参 阅图 4， 该第一滑条 3311及第二滑条 3313分别可滑动地容置于滑轨 31 内， 且一^ IN主 34穿过该限位块 33的长条状腰形装配孔 3314并可沿设 于滑轨 31上的弯折滑槽 3101滑动。该定位块 332从轨道 31的通槽 3104 穿过并部分伸出， 且该定位块 332可沿该通槽 3104往返滑动。
由于滑轨 32在轨道 31的底板 310所设的内轨 312上滑动， 而限位 块 33沿邻近滑轨 31第一端的底板 31滑动， 如图 4及图 6所示， 当滑 动机构 3处于关闭状态时， 该限位块 33位于滑轨 32和轨道 31之间的 空间内， 且卡柱 34—端与滑轨 32上所设的卡口 322卡固端 3221过盈 配合以卡因在卡口 322内， 另一端容置于轨道 31上的弯折滑槽 3101的 滑行槽 3102邻近轨道 31第一端处。 该限位块 33的定位块 332位于通 槽 3104邻近轨道 31的第一端处。
上迷是单个滑动机构 3在关闭状态的结构介绍。 请一并参阅图 7 , 当所有滑动机构 3均在关闭状态时，该多个滑块 21对应的限位螺钉 217 均位于其长条状腰形装配孔 216 靠上方的一端， 且每相邻两个滑块 21 通过其第三侧板 214与第四侧板 215形成的平滑接触面平滑相接且于相
接处形成一个楔形开口。该若千滑块 21可滑动的自由空隙与定位块 332 的厚度相当， 以使该若干滑块 21 可滑动的自由空隙只能满足一次只能 打开一个滑动机构 3。 同时， 限位块 33的定位块 332位于可滑动地设于 轨道 31 的第一端处， 且限位块 33上的定位块 332穿过轨道 31上通槽 3104邻近轨道 31的第一端处， 并伸至相邻两个滑块 21相接处的楔形开 o 。
请一并参阅图 8及图 9。 当滑动机构 3打开时， 在外力作用下， 滑 轨 32向远离轨道 31第一端的方向滑动， 卡柱 34带动定位块 33—起跟 随滑轨 32滑动， 直至卡柱 34滑至弯折滑槽 3101的卡止槽 3103 , 卡柱 34沿定位块 33的长条状腰形装配孔 3314落入卡止槽 3103 , 同时， 限 位块 33的定位块 332从通槽 3104邻近轨道 31 的第一端处滑动， 且止 于通槽 3104的另一端。 此时， 在外力作用下， 滑轨 32继续滑行， 而卡 柱 34滑入滑轨 32的卡口 322的敞口释放端 3222 , 并因定位块 332止于 该轨道 31上的通槽 3104端部， 从而使定位块 33脱离滑轨。
请进一步参阅图 10 , 当某一滑动机构 3在打开状态时， 该滑动机构 3的限位块 33的定位块 332滑至通槽 3104远离轨道 31的第一端处，且 停止于通槽 3104。 同时， 止于通槽 3104的另一端。 该定位块 332从其 对应的相邻两个滑块 21 相接处的楔形开口滑入， 并沿该相邻两个滑块 21的平滑接触面滑入至该相邻两个滑块 21之间， 使该相邻两个滑块 21 中位于上方的滑块 21向上移动， 从而使该多个滑块 21对应的限位螺钉 217移至其 条状腰形装配孔 216靠下方的一端。 由于该上方滑块 21向 上移动的动力， 该相邻两个滑块 21之上的所有滑块 21均同步上移动。 此时， 除该相邻两个滑块 21之外的所有滑块 21对应的定位块 332， 均 与并其对应的相邻两个滑块 21相接处的楔形开口错开， 且所有滑块 21 均不可移动。 也即， 此时， 其他滑动机构 3均因定位块 332受到滑块 21 的阻止而无法打开， 从而实现一次只能打开一个滑动机构 3的效果。
请一并参阅图 i及图 i i， 本实施例中， 互相制约式安全型多抽屉锁 定机构还包括一锁固机构 4。 该锁固机构 4包括锁头 41、 锁杆 42、 固定 锁片 43和滑动锁片 44。 该锁杆 42主体呈长杆状， 其一端连接锁头 41， 另一端连接固定锁片 43并与滑动锁片 44相 合。 滑动锁片 44一端设 于所述限定机构 2的滑块 21上方， 且当所有滑动机构 3均关闭时， 且 锁固机构 4未启用状态下， 该滑动锁片 44一端与最上方的一滑块 21之 间的距离与定位块 332的厚度相当。 该滑动锁片 44受锁杆 42移动的控 制。 需要锁定所有滑动机构 3时， 通过控制锁头 41 , 带动锁杆 42相对 固定锁片 43发生向左旋转， 进一步带动滑动锁片 44向左移动， 从而 (骨 动锁片 44的一端紧压于最上方的一滑块 21 , 则所有滑块 21均不可上下 移动。 此时， 所有滑动机构 3均因定位块 332受到滑块 21 的阻止而无 法打开， 从而实现锁定全部滑动机构 3的效杲。
需要打开锁固机构 4时， 反向控制锁头 41 , 带动锁杆 42相对固定 锁片 43发生向右旋转， 进一步带动滑动锁片 44向右移动， 恢复至锁固 机构 4未启用状态， 该滑动锁片 44一端与最上方的一滑块 21之间的距 离与定位块 332 的厚度相当。 此时， 任一滑块 21 可带动其上方的滑块 21在定位块 332的作用下向上移动， 从而实现打开一只抽屉 5的效果。
基于上述构思的本发明互相制约式安全型多抽屉锁定机构， 由于从 结构上确保在非锁定状态下主轴上只存在允许打开一个抽屉的自由空 隙， 所以在已打开一个抽屉的情况， 绝对不会发生同时打开第二个或二 个以上抽屉的情况， 因而既便于使用者有的放矢地打开目标抽屉， 提高 工作效率，也便于各抽屉间的物品不会互相混淆， 带来了管理上的方便， 且可以通过钥匙锁定的方式锁定全部抽屉， 所以无论在多么复杂的工作 环境中使用设置有本发明的互相制约式安全型多抽屉锁定机构的多抽 屉式安全拒， 均具有极大的使用方便性和工作可靠性， 能彻底克服现有 技术中多个抽屉同时滑出、 工具箱柜失去重心、 引发倾倒、 工具洒滚满
地的不堪局面或安全事故， 因而具有显著的实用性和广阔的市场应用前 景。
以上所述， 仅是本发明的实施例而已， 并非对本发明作任何形式上 的限制， 虽然本发明已以实施例揭露如上， 然而并非用以限定本发明， 任何熟悉本专业的技术人员， 在不脱离本发明技术方案范围内， 当可利 用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例， 但凡是未脱离本发明技术方案内容， 依据本发明的技术实质对以上实施 例所作的任何简单 ^改、 等同变化与修饰， 均仍属于本发明技术方案的 范围内。
