此外，下面所描述的本发明不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
如图1所示，一种棱镜装置，包括相互连接的棱镜组件1和支架2，支架2的一端贯穿台桌3并通过支撑座4固定在台桌3上。在其他实施方式中，支架2还可以通过支撑座4直接支撑在地面上，或夹持固定在台桌边缘的方式。通过将棱镜组件1固定在支架2上，使用者可以通过棱镜组件1观看到台桌3上垂直于视觉角度的待观看物5。与现有技术中的佩戴式的棱镜相比，无需在鼻梁上佩戴棱镜组件1，减轻了使用者鼻梁骨的承重以及佩戴异物的不舒适感；而且当视野随着头部运动而发生变化的情况下，不会对人造成眩晕感；此外，使用者可以随时从桌面视野上抽离，保持了对周围环境的快速感知和反应能力。
具体的，如图2所示，在本实施例的第一种实施方式中，支架2具有相对设置的第一端和第二端，支架2的第一端通过支撑座4固定在台桌3上，支撑座4为支架2在台桌3上提供支撑点位置，支架2的第二端与棱镜组件1连接，支架2的第二端可相对支架2的第一端运动以调节棱镜组件1相对支撑点位置 的空间位置。
在使用棱镜组件1的过程中，先将支架2的第一端固定在台桌3上，再调节支架2第二端相对支架2第一端的空间位置，即可调节棱镜组件1相对使用者的距离和高度，使棱镜组件1可以更好地对准人体眼部视野的方向，实用性更强。而且，使用者通过棱镜组件1无需弯曲背部和颈部脊椎即可观看到垂直于视觉角度的内容，减少背部和颈部脊椎的压力，可以纠正人体观看垂直于视觉角度的内容时的坐姿或躺姿。
在本实施例的第一种实施方式中，支架2包括高度可调节的杆体21、平行四连杆支撑组件23和角度调节结构22。杆体21的一端与支撑座4连接，平行四连杆支撑组件23连接在杆体21远离支撑座4的一端，角度调节结构22连接在平行四连杆支撑组件23和棱镜组件1之间，且至少有一端与平行四连杆支撑组件23和棱镜组件1转动连接。在本实施例的其他实施方式中，还可以无需采用平行四连杆支撑组件23，棱镜组件1和杆体21通过角度调节结构22直接相连。在调节棱镜组件1相对使用者的距离和高度的过程中，可以先通过调节杆体21在台桌3上的安装位置及杆体21的高度进行粗调节；再通过平行四连杆支撑组件23对棱镜组件1相对于支撑座4的空间位置进行精调节，可以使棱镜组件1更好地对准人体眼部视野的方向；最后通过角度调节结构22调节棱镜组件1的上下俯仰角度和左右偏斜角度。这种支架1的可调式结构，使棱镜组件1的灵活性和实用性得以大大提高；而且由于平行四连杆支撑组件23可以进行微小角度的调节，方便将棱镜组件1更精准地调节到合适的观察位置。
在本实施例的第一种实施方式中，杆体21包括两节转动连接的连接杆211，相邻两节连接杆211通过带自阻尼的机械轴连接，位于下端的一根连接杆211转动连接在支撑座4上，位于上面的一根连接杆211可以绕两连接杆211之间的机械轴在三维空间上任意转动并悬停。通过旋转位于上面的一根连接杆211，即可实现对棱镜组件1相对支撑座4的空间位置的粗调节，具有结构简单、操作方便的优点。在其他实施方式中，通过带自阻尼机械轴连接的连接杆211数 量还可以是三根或以上，两根连接杆211之间可以是带自阻尼沿垂直轴或水平轴的旋转。连接杆21还可以采用伸缩套杆等其它可伸缩调节的方式。
在其他实施方式中，两节连接杆211可以通过允许连接杆之间变换角度，同时又能在不同角度停留，并提供稳定的镜体支撑的任何其他方式进行连接，连接方式包括但不限于各种阻尼轴、弹簧结构、气缸、液压和摩擦套筒等。
在本实施例的第一种实施方式中，平行四连杆支撑组件23的一端通过转动连接座24活动连接在连接杆211远离支撑座4一端的端部，平行四连杆支撑组件23的另一端连接有顶座25，角度调节结构22连接在顶座25上。平行四连杆支撑组件23还可以绕垂直轴转动，从而进一步提高了支架2的可调性。
具体的，平行四连杆支撑组件23包括两根长度相同且相互平行的连杆、以及连接在位于上方的一根连杆和转动连接座24之间伸缩机构，两根连杆的两端分别转动连接在转动连接座24和顶座25上，伸缩机构为平行四连杆支撑组件23提供支撑。从平行四连杆支撑组件23的侧面看，两根连杆在转动连接座24和顶座25上的四个铰接点在同一平面的连接构成平行四边形结构。转动连接座24上的两个铰接点之间的连线可看作平行四边形结构的第一边，而顶座25上两个铰接点之间的连线可看作平行四边形结构的第二边，第一边和第二边相对设置，两根连杆分别作为平行四边形结构的另外两条相对的第三边和第四边。
绕连杆与转动连接座24的铰接点转动连杆，可通过平行四边形结构带动顶座25相对转动连接座24进行运动，从而调整顶座25相对于转动连接座24的方位，且这样调节方式相对于两根连接杆211通过绕带自阻尼连接轴的转动来实现顶座25位置调节的方式相比，可以进行更加细小方位的调节；同时，伸缩机构能为平行四边形结构提供支撑，使顶座25能够在任意位置悬停。支架2通过带自阻尼机械轴的两个连接杆211和平行四连杆支撑组件23配合进行棱镜组件1位置调节的方式，可以进行一些更小角度的调节，棱镜组件1的位置调节结构的精确度更高，从而可以使棱镜组件1能更加精确地对准人体眼部视野的方向，使使用者观看更加清楚。具体的，伸缩机构采用弹簧组件，弹簧组件 一端安装在转动连接座24上，另一端安装在其中一根连杆上。在平行四连杆支撑组件23转动时，在不同角度，弹簧组件的转动角度不同，弹力值也随之发生变化；平行四连杆支撑组件23可以在任意角度都处于受力平衡状态，及顶座25能相对转动连接座24在任意位置悬停。更进一步的，弹簧组件可以是气弹簧组件或压缩弹簧组件等。在其他实施方式中，伸缩机构还可以采用直线推杆代替。
在本实施例的第一种实施方式中，角度调节结构22包括球头连杆221，球头连杆221的一端活动连接在顶座25上、另一端具有嵌入棱镜组件1内的连杆球头222；棱镜组件1绕连杆球头222的球面带自阻尼转动连接于连杆球头222。这种带自阻尼转动连接的球头连杆221和棱镜组件1构成的方式，可以任意调节棱镜组件1相对于球头连杆221的角度，可调性高。在其他实施方式中，球头连杆221与顶座25连接的一端也可以是带自阻尼的转动连接方式。
如图3所示，在本实施例的第二种实施方式中，与第一种实施方式的不同之处在于，杆体21通过支撑座4直接支撑在地面上，杆体21包括两节依次套接的空心支杆212和用于锁紧相邻两根空心支杆212的第二锁紧件213，第二锁紧件213可以采用锁环、环形卡箍或锁紧螺丝等方式。在其他实施方式中，空心支杆212的数量可以是三根或以上；与支撑座4连接的一根空心支杆212可以是固定在支撑座4上，也可以是转动连接在支撑座4上。
角度调节结构22包括转动连接于空心支杆212上端的转动杆223、用于将转动杆223锁紧于杆体21第一锁紧件224；棱镜组件1沿转动杆223的轴线方向滑动安装于转动杆223。第一锁紧件224可以采用与空心支杆212螺纹配合的锁紧螺丝。松开第一锁紧件224，转动所述转动杆223并带动棱镜组件1转动，再用第一锁紧件224将转动杆223锁定在空心支杆212上，即可调节转动杆223及棱镜组件1相对于台桌3的上下俯仰角度和左右偏斜角度。
具体的，棱镜组件1包括镜体11和滑动设置于转动杆223上的连接件13。镜体11的上端固定有第一磁体12，连接件13的下端固定有第二磁体14，镜体 11通过第二磁体14与第一磁体12的磁吸配合固定在连接件13上。连接件13还活动连接有用于将连接件13锁定在转动杆223上的第三锁紧件，第三锁紧件具体可以为锁紧螺丝。在其他实施方式中，棱镜组件1还可以通过机械卡扣固定、胶粘固定等方式连接在支架2上。支架2与棱镜组件1连接的一端可以整体或部分嵌入棱镜组件1内或夹持棱镜组件1，棱镜组件1也可以部分或整体嵌入支架2的一端。
如图4所示，在本实施例的第三种实施方式中，与第一种实施方式的不同之处在于，支架2采用可弯曲变形的可塑性弯管26制成，可塑性弯管26具体可以是鹅颈弯管或蛇形弯管。在本实施方式中，可塑性弯管26的一端可以通过支撑座4连接在台桌3上，棱镜组件1可转动式地连接在可塑性弯管26的另一端；可塑性弯管26与棱镜组件1连接的一端可绕另一端转动，从而调整棱镜组件1相对于支撑座4的空间位置。
在其他实施方式中，支架或杆体可以通过能够稳定支持杆体的任意方式进行固定，包括但不限于，配重落地、夹具、螺钉或丁卯固定、负压吸盘、磁吸、粘胶粘合等方式。
在本实施方式中，棱镜组件1包括镜体11和夹具15；夹具15转动连接于可塑性弯管26的第二端，包括两个相对设置且弹性连接的夹持臂151、以及连接于两个夹持臂151之间的驱动两夹持臂151配合夹紧镜体11的弹性件152。弹性件152可采用一个或多个弹簧构成。
在其他本实施方式中，可塑性弯管26还可以通过与可塑性弯管26固定连接的配重块直接放置在台桌3上，或与可伸缩的杆体21结合作为棱镜组件1的支架2。棱镜组件1也可以是固定在支架2上，支架2采用不仅自身可弯曲、且能够绕自身轴线方向旋转的金属软管；采用这种金属软管制作的支架，可以仅通过转动金属软管同时调节棱镜组件1相对于支撑点的空间位置以及相对于台桌3的上下俯仰和左右偏斜角度，结构简单，便于调节。
综上所述，本实施例提供的棱镜装置，采用支架2支撑棱镜装置1的方式， 在通过棱镜组件2观看时，无需在鼻梁上佩戴棱镜组件1，减轻了佩戴者鼻梁骨的承重以及佩戴异物的不舒适感；而且当视野随着头部运动而发生变化的情况下，不会对人造成眩晕感；此外，使用者可以随时从桌面视野上抽离，保持了对周围环境的快速感知和反应能力。另一方面，支架2的可调节性好，可以任意调节棱镜组件1相对于使用者的空间位置以及上下俯仰和左右偏斜角，使棱镜组件1能更好地对准人体眼部视野的方向，实用性更强；而且，使用者通过棱镜组件1无需弯曲背部和颈部脊椎即可观看到垂直于视觉角度的内容，减少背部和颈部脊椎的压力，可以纠正人体观看垂直于视觉角度的内容时的坐姿或躺姿。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
