下面结合具体实施例和附图对本发明作进一步说明，在以下的描述中阐述 了更多的细节以便于充分理解本发明， 但是本发明显然能够以多种不同于此描 述的其它方式来实施， 本领域技术人员可以在不违背本发明内涵的情况下根据 实际应用情况作大致推广、 演绎， 因此不应以此具体实施例的内容限制本发明 的保护范围。
图 1示出了本发明的医用吊塔臂系统 100的前视图。图 2示出了本发明的 医用吊塔臂系统 100的局部剖开立体图。 图 3示出了本发明的用于医用吊塔臂 系统 100的转轴 11、 21 的立体图， 其中为了清楚起见， 其上下关系进行了颠 倒 （即， 与安装在医用吊塔臂系统 100中时的上下关系相反）。 图 4示出了本 发明的用于医用吊塔臂系统 100的转轴 11、 21 的局部剖开立体图， 其中为了 清楚起见， 其上下关系进行了颠倒。 图 5示出了本发明的用于医用吊塔臂系统 100的转轴 11、 21的剖面图， 其中为了清楚起见， 其上下关系进行了颠倒。
本发明的医用吊塔臂系统 100包括：
锚板 10， 锚板 10用于固定至医用吊塔臂系统安装空间的顶部结构， 该顶 部结构例如是医院手术室、 重症监护室的天花板；
第一转轴 11，第一转轴 11包括轴外圈 111、轴内圈 112和滚珠间隔套 113， 滚珠间隔套 113设置于轴外圈 111和轴内圈 112之间， 轴外圈 111的下部形成 矩形法兰 114， 轴外圈 111的上部形成圆形法兰 115， 其中， 第一转轴 11的圆 形法兰 115直接固定至锚板 10或借助延长柱 20固定至锚板 10; 以及
第一臂 12， 第一臂 12在其一个端部附近固定至第一转轴 11 的矩形法兰 114。
也就是说， 转轴 11的上部圆形法兰 115与下部矩形法兰 114是一体形成 的。
这样， 本发明的医用吊塔臂系统能实现模块化设计， 整体结构紧凑， 装配 简单且装配时间短， 零部件较少， 可以选择性地安装电磁刹车或气囊刹车。
需要注意的是， 本文所用的 "上"、 "下"、 "前"、 "后"、 "左"、 "右"等只 是为了便于描述本发明而定义的示例性方向。 例如， 如图 1所示， 纸面上侧方 向为 "上"， 纸面下侧方向为 "下"； 而如图 5所示， 为了清楚起见， 其上下关 系进行了颠倒， gP， 纸面上侧方向为 "下 "， 纸面下侧方向为 "上"。 当然， 本 领域技术人员在本发明的基础上可以理解， 也可以其它方式定义 "上"、 "下"、 "前"、 "后"、 "左"、 "右"等方向， 同样落入本发明的保护范围之内。
较佳的是， 本发明的医用吊塔臂系统 100还包括：
第二转轴 21， 第二转轴包括轴外圈 111、 轴内圈 112和滚珠间隔套 113， 滚珠间隔套 113设置于轴外圈 111和轴内圈 112之间， 轴外圈 111的下部形成 矩形法兰 114， 轴外圈 111的上部形成圆形法兰 115， 其中， 第二转轴 21的圆 形法兰 115固定至第一臂 12的另一个端部附近； 以及
第二臂 22， 第二臂 22在其一个端部附近固定至第二转轴 21 的矩形法兰
114。
这样， 构成了整体结构紧凑的双臂系统， 尤其有效地缩短了臂与臂之间的 距离， 装配简单且装配时间短， 零部件较少， 可以选择性地安装电磁刹车或气 囊刹车。
较佳的是， 第一转轴 11和第二转轴 21是相同的转轴。 此外， 较佳的是， 第一臂 12和第二臂 22是相同的臂。
这样， 本发明的医用吊塔臂系统能实现模块化设计， 其主要部件（转轴和 /或臂） 能彼此替代， 节约了生产成本和更换成本。
虽然上述给出的实施例仅仅描述了一个转轴和一个臂或两个转轴和两个 臂的情况， 但本领域技术人员在本发明的基础上可以理解， 也可采用三个以上 转轴和三个以上的臂。 这样的变型同样落入本发明的保护范围之内。
以双塔的情况为例， 其中一个医用吊塔 （图 1 左侧医用吊塔） 的转轴 11 的圆形法兰直接连接固定至锚板 10， 另一医用吊塔（图 1右侧医用吊塔）为了 避免相互干涉需在转轴 11的圆形法兰上安装延长柱 20。 也就是说， 图 1右侧 医用吊塔的转轴 11的圆形法兰借助延长柱 20固定至锚板 10。
为了保证该延长柱 20的高度尺寸足够小， 较佳的是， 臂 12、 22的端部是 下斜切的。 这样， 可以进一步减小医用吊塔臂系统的占用空间， 并增加整体结 构紧凑性。
此外， 为了保证两个医用吊塔的转轴 11、 11的中心距为 300mm以下， 将 转轴设计成圆形法兰在上、 矩形法兰在下 （即， 轴外圈的下部形成矩形法兰， 轴外圈的上部形成圆形法兰） 的布局。 这样， 不仅可以缩短两个医用吊塔的转 轴中心距， 还可以使得延长柱罩的外观更加简洁美观。
转轴 11、 21下部矩形法兰设计成矩形是为了能在转轴 11、 21的下端安装 例如 120Nm刹车力矩的电磁刹车， 或者在不改变转轴结构前提下也可以根据 客户要求安装气囊刹车。 也就是说， 较佳的是， 转轴的矩形法兰能用于安装电 磁刹车或气囊刹车。 具体地说， 例如， 轴内圈 111上可以设置电磁刹车卡口和 气囊刹车垫板固定孔， 轴外圈 112上可以设置电磁刹车固定孔或气囊刹车固定 孔。
较佳的是， 医用吊塔臂系统还包括设置于转轴 11、 21外侧的转轴盖 31、 32， 转轴盖在其上转轴盖 31和下转轴盖 32之间设有环形槽， 用于安装环形刹 车指示灯。 当某个转轴 11、 21的刹车释放时， 环形刹车指示灯会亮起。
较佳的是， 臂 12、 22的端盖由两部分构成： 端盖外壳和端盖固定板， 其 中， 安装端盖时， 先将端盖固定板通过若干个 （例如两个） 螺钉与臂 12、 22 内侧的若干个螺纹孔固定，然后直接将端盖外壳推入到端盖固定板上的相应孔 内。 这样， 缩短了臂端盖的安装与拆卸时间， 降低了安装复杂性。
较佳的是，如图 3-5所示，转轴 11、 21还包括机械刹车 118，机械刹车 118 外周带有螺纹， 以拧入转轴 11、 21的矩形法兰 114的螺纹孔中。 机械刹车 118 的数量可根据空间增加， 从而增加阻尼转矩。 例如， 在图 3-5所示的示例中， 采用了四个机械刹车 118。
较佳的是， 为减小转轴 11、 21与臂 12、 22 (通常为铝型材） 连接处的接 触应力及增加连接强度， 医用吊塔臂系统还包括分别设于转轴的上端和下端的 上衬板 41和下衬板 42。
较佳的是， 臂 12、 22的上表面设有开口 51、 52。 这样， 一方面可以方便 气管和线路的装配， 另一方面可以根据客户要求选装顶部环境照明 LED灯。
较佳的是， 如图 3-5所示， 转轴 11、 21还包括设于其上部外侧的限位柱 119和限位块 120。 例如， 转轴 11上部的圆形法兰共设有均布的 6个圆孔， 但 基于它们承受的倾覆力矩差异， 转轴 21只需使用 4个孔。
较佳的是， 如图 3所示， 限位柱 119待与限位块 120接触的区域上还可设 有缓冲垫 121。
较佳的是，如图 5所示，转轴 11、 21还包括上密封圈 117和下密封圈 116， 上密封圈 117设置于轴外圈 111的上部内侧与轴内圈 112的上部外侧之间， 下 密封圈 116设置于轴外圈 111的下部内侧与轴内圈 112的下部外侧之间。
如图 2所示，当第一转轴 11的圆形法兰 115借助延长柱 20固定至锚板 10 时， 为了医用吊塔臂系统的美观和清洁起见， 可在延长柱 20外侧设置延长柱 罩。
图 6示出了用于医用吊塔臂系统的延长柱的另一实施例， 其中， 图 6 (a) 示出了延长柱安装在医用吊塔臂系统中时的局部剖开示意图， 图 6 (b)单独示 出了延长柱的立体图。
该延长柱 20'由沿圆周分布有多个延长柱孔腔 201的圆筒件构成。 当第一 转轴 11的圆形法兰 115借助延长柱 20'固定至锚板 10时， 多个螺杆分别穿过 多个延长柱孔腔 201， 且其下端与位于第一转轴 11中的螺纹孔相连接，其上端 穿过锚板 10中的光孔（无螺纹孔） 并通过设置于锚板 10上方的螺母拧紧。 该 延长柱 20'可进行外表面喷涂。 这样， 省去了设置于延长柱外侧的延长柱罩。
图 7 (a) 示出了用于医用吊塔臂系统的机械刹车的前视图， 图 7 (b) 示 出了用于医用吊塔臂系统的机械刹车的立体图。
机械刹车 118包括安装时 （即， 安装在转轴中时） 位于外侧 （即， 远离轴 内圈的一侧） 的螺纹部 1183、 安装时位于内侧 （即， 朝向轴内圈的一侧） 的摩 擦头 1181、 以及位于螺纹部 1183和摩擦头 1181之间的碟簧 1182。 在要将机 械刹车 118安装在转轴中时， 可用螺丝刀将机械刹车 118拧入， 达到一定扭矩 后， 摩擦头 1181受到碟簧 1182的压力顶紧轴内圈 111的外圆柱面。
上面结合附图对本发明进行了示例性描述，显然本发明的具体实现并不受 上述实施方式的限制。 本领域技术人员可在不偏离本发明技术构思的前提下， 对本发明作出各种修改或变型， 这些修改或变型当然也落入本发明的保护范围 之内。
