实施本发明的最佳方式 如图 1至图 3所示：本实施例的一种显示器转轴，包括一支架 1， 一顶部绞链，一底部绞链， 一限位架 41。转轴组成图可参考（图 1 )， 支架上部为中空筒体转杆， 支架下部亦为中空筒体转杆， 支架 1前后 运动调整显示屏高度。 顶部绞链包括两个顶部左 /右转轴 21、 22， 顶 部左右转轴 21、 22套在支架上部转杆两侧。 顶部左右转轴 21、 22位 于显示屏后，其功能是实现显示屏前后的角度调整， 调整范围： -5° 一 -140° 。限位架 41安装在与支架 1平行的位置，在顶部转轴与限位架 相接处有一做为限位卡槽的凹槽， 其位于顶部转轴上， 与限位支架的 顶部的突出部分相互配合， 当按下限位支架 41时， 顶部的突出部分 将脱离顶部转轴上的限位卡槽， 此时， 顶部转轴可以做大范围 - 5°—140°的前后角度调整， 当顶部转轴转动到前后角度为 -5°- -25° 时， 顶部转轴将与限位卡槽自动重合。 限位架主要实现用户对显示屏 高度位置的调节。限位支架 41的材质为淬火钢，限位片的调整是采用 杠杆原理实现； 顶部左右转轴的材质均采用铝合金， 其转动是釆用弹 簧片 5实现的。 转轴支架 1的材质是锌合金， 其主要作用是支持和连 接作用。与底座相连的铰链是底部转轴，其包括两个底部左右转轴 31、 32, 底部左右转轴 31、 32通过与左右两个弹簧 33、 34相接套在支架 1下部转杆的两侧， 底部左右转轴 31、 32、左右弹簧 33、 34主要实现 了配合支架 1下部转杆调节支架位置， 通过下部转轴与转杆之间的摩 擦以及弹簧的控制达到支架位置固定， 实现调节显示屏高度的功能， 其可实现显示屏上下的角度调整（0° -50° )， 能使显示屏与底座紧 贴， 其中底部左右转轴 31、 32采用矩形弹簧 33、 34， 使底部转轴的 调整范围达到， 底部左右转轴 31、 32的材质均采用铝合金。
各部分组成实现功能及工作原理如下：
底部左右转轴 31、 32、 左右矩形弹簧 33、 34主要实现了配合支 架下部转杆调节支架位置， 通过下部转轴与转杆之间的摩擦以及弹簧 的控制达到支架位置固定。 实现调节显示屏高度的功能。 其工作原理 为： 下部左右转轴 31、 32通过与左右两个弹簧 33、 34相接套在支架 下部转杆的两侧， 当用户需要调节显示屏的高度时， 通过提升或者下 压支架， 支架的下部转杆绕下部左右转轴旋转， 转轴与支架之间有很 大的摩擦力， 可以对用户调整的任意位置迸行保持平衡。 左右弹簧用 于用户在向上提升支架时提供向上反弹支架的作用力， 这样一方面可 以节省力气， 另一方面也可以避免因需要过大力气而拖起底座。 并且 向上的反弹力还可以平衡显示屏自身重力， 防止显示屏的翻倒。 最终 满足显示屏高度位置的任意性。
支架 1主要起对显示屏高度位置的调节， 同时负担整个显示屏的 重力与平衡。 其工作原理为： 当用户需要调节显示屏高度时， 只要直 接握住显示屏来调节即可， 支架 1 通过下部转杆在左右转轴 31、 32 的旋转进行高度的调整。
限位架主要由三部分组成： 限位支架 41， 限位弹簧 42， 十字槽 盘头机钉 43。 主要实现用户对显示屏角度与高度调整有特殊的要求， 用户可以通过调节限位支架使限位模块不起作用， 显示屏可以被调整 到与底座平行的位置， 实现壁挂功能。 限位支架安装在与支架平行的 位置， 在顶部转轴与限位支架相接处有一凹槽， 通常情况下 （即限位 弹簧开关按下去） 限位弹簧开关突出部分刚好伸进凹槽中， 这样在顶 部转轴旋转时， 会因受到限位支架的控制 （即限位功能）旋转只能在 较小的范围。 当限位弹簧 42松开后， 限位支架 41的突出部分滑出凹 槽， 顶部转轴的旋转因此而变的自如。 角度调节范围变大。
顶部左右转轴 21、 22实现固定显示屏， 调节显示屏角度。其工作 原理为： 顶部左右转轴套在支架上部转杆两侧， 当用户需要调节显示 屏的角度时， 只需握住显示屏前后调整， 调节过程中下部转轴， 支架 保持不动，只有上部左右转轴在转杆上旋转，达到调节显示屏的角度。
参见图 4至图 5本实用新型在实现显示屏的高度调节时， 顶部， 底部转轴保持不动， 只有底部左右弹簧和支架在调整， 支架在受到下 压或者上提的外力后，支架连接的底部左右弹簧也会相应的受到外力。 弹簧在受到外力的情况下， 会产生向上反弹支架的作用力平衡了显示 屏自身的重力， 节省了外力， 保持了显示屏的稳固。 转轴与下部转杆 之间的摩擦力保持了显示屏被调节的高度位置。 二者的结合共同完成 高度任意调节。 在实现显示屏的角度调节时， 限位模块起作用时 （即 自然状态）， 下部转轴由其左右弹簧的回弹力保证限位支架与顶部转 轴， 底部转轴紧密相接， 这种情况下， 显示屏角度仅被调节的范围可 以达到前倾 5度，后仰 25度。这和目前市场上的转轴简单实现显示屏 的前后角度的调整的区别不是很大。 为了满足用户对显示屏转动角度 与高度的特殊要求， 我们采用限位支架。 通过限位支架在不同状态下 的工作情况满足角度调节要求。 限位支架不起作用时， 顶部转轴旋转 范围变大， 角度调节范围也扩大。 当限位支架不再限位时， 限位支架 与顶部， 底部的转轴松开， 这时如果支架不动， 顶部转轴可以向后转 动 140 度； 如果顶部转轴不动， 支架可以绕底部转轴的轴心转动 50 度； 如果同时转动顶部转轴和支架， 则可以转到使显示屏面与转轴底 座平行。 因此此款使用新型转轴非常紧凑， 而且当显示屏转至与底座 平行时， 显示屏与底座紧贴在一起。 可以实现壁挂功能， 又可以节省 大量的占用空间和包装空间。 用户操作非常方便。 该转轴结构还可使 底座和显示屏转到平行位置， 实现不拆底座而实现壁挂的功能， 这样 不仅美观而且还可以大大节省空间。 工业应用件 本实用新型转轴可广泛使用于电脑设备中的显示器上， 包括一般 台式电脑的液晶显示器（LCD)和笔记本电脑显示器，其基本功能使显 示器的倾斜角度能随使用者个人需要而调整， 并最大限度地满足使用 者越来越高的需要， 包括满足使用者根据自己所处位置的具体情况调 整显示屏的角度和高度， 使其符合人体工学的需要。
