具体实施方式
如图1所示，本发明的升降装置，包括：在升降后提供保持作用力且使用流体作为阻尼介质的弹簧1、第一套管2、第二套管3、滚动摩擦组件4、滑动摩擦组件5、连接组件6、控制组件7，下面对每部分以及它们之间的关系进行详细地说明：
如图1和图2所示，弹簧1优先采用气弹簧。所述弹簧1的一端位于第一套管2中且与第一套管2的一端固定，第一套管2由第一方管2a和底板2b组成，底板2b固定在第一套管2的一端，弹簧1的一部分位于第一方管2a中，且弹簧1的一端与底板2b固定连接。
如图1和图3所示，第二套管3的一端从所述第一套管2的另一端插入到该第一套管2中，第二套管3由第二方管3a以及容纳盒3b组成,容纳盒3b固定在第二方管3a的端部，容纳盒3b的底部设有通孔3c，该通孔3c与第二方管3a的内孔连通。
如图所示，在第一套管2和/或第二套管上3设有用于第二套管升降的导向组件；所述导 向组件为滚动摩擦组件或者滑动摩擦组件。本实施方式中，在第一套管2上连接的是滑动摩擦组件5，在第二套管3上连接的是滚动摩擦组件4。关于滚动摩擦组件和滑动摩擦组件的具体结构如下：
如图1、图4和图5所示，所述滚动摩擦组件4包括衬套4a、滚动体4b，所述衬套4a的材质优先选用塑料，由于第一套管2和第二套管3均为方形管，因此，衬套4a的形状为与第一套管和第二套管相适配的方形。所述衬套4a上设有窗口4c，优选地，在衬套4a的四个侧壁面上均设有多个窗口4c，所述滚动体4b设置在该窗口4c中。优选地，所述滚动体4b呈柱状，滚动体4b的两端分别设有连接轴4d，所述衬套4a上设有位于窗口侧壁面上的装配槽4e，滚动体4b两端的连接轴4d位于所述装配槽4e中，而在装配槽4e的口部设有凸起4f,当连接轴4d嵌入到装配槽4e中以后，凸起4f可以对连接轴4d形成限位，限制连接轴4d侧向滑出。所述滚动体4b的周面上设有环形槽4g，所述衬套4a上设有位于窗口中的挡杆4h，滚动体4b安装到窗口4c中后，挡杆4h嵌入到滚动体4b上的环形槽4g中，环形槽4g位于滚动体的中部，这样，滚动体4b的中间部位受到支撑作用力，当第二套管3在升降过程中，滚动体4b沿第一套管的内壁面滚动，通过滚动体与第一套管的这种接触，既对第二套管形成了导向，对减小了摩擦作用力。滚动摩擦组件4连接于第二套管3的插入到第一套管2中的端部，两者的具体连接结构为：在第二方管3a的侧壁面上设置第二连接孔3d，所述衬套4a的一端设有所述导向套的侧壁上设有槽，衬套4a上设有位于所述槽中的弹片4i，该弹片4i的一端与衬套4a固定为一体，弹片4i的另一端为自由端，该自由端上设有齿4j。衬套4a插入到第二方管3a中，在插入过程中，弹片4i的自由端上的齿4j受挤压而使弹片4i整体向内侧倾斜，当齿4j与第二连接孔3d对应时，第二连接孔为齿4j让出空间，这时，在弹性回复作用力下，齿4j进入到第二连接孔3d中，使衬套4a与第二方管3a形成扣接。
如图1和图6所示，所述滑动摩擦组件5包括导向套5a，该导向套5a的内壁面上设有凸筋5b。由于第一套管2和第二套管3均为方形管，因此，导向套5a的形状为与第一套管2和第二套管3相适配的方形。所述导向套5a的侧壁上设有凹槽，导向套5a上设有位于所述凹槽中的连接部件5c，该连接部件5c的一端与导向套固定为一体，连接部件5c的另一端为自由端，该自由端上设有凸起部5d。在第一套管2的管壁上设有孔，导向套5a插入到第一套管2中，在插入过程中，连接部件5c的自由端上的凸起部5d受挤压而使连接部件5c整体向内侧倾斜，当凸起部5d与第一套管2的孔对应时，孔为凸起部5d让出空间，这时，在弹性回复作用力下，凸起部5d进入到孔中，使导向套5a与第一套管2形成扣接。
如图1、图7至图9所示，连接组件6设置于第二套管的另一端，所述弹簧1的另一端穿过第二套管3与连接组件配合。所述连接组件6包括：弹簧连接件6a、第一连接轴6g、拉索连接件6h、第二连接轴(图中未示出)，弹簧连接件6a的一端设有沿该弹簧连接件径向布置第一轴孔6b，另一端设有沿该弹簧连接件轴向布置的安装孔6c，弹簧连接件6a的侧壁上设有安装槽6d，该安装槽6d位于第一轴孔6b与安装孔6c之间且沿弹簧连接件6a径向布置，弹簧连接件6a的侧壁上还设有位于安装槽槽口两侧的支撑块6e，支撑块6e上设有第二轴孔6f；第一连接轴6g的两端与第二套管3固定，且第一连接轴6g从弹簧连接件上的第一轴孔6b穿过；拉索连接件6h通过第二连接轴铰接在支撑块6e上，拉索连接件6h的一端位于所述安装槽中。拉索连接件6h大致呈弓形，拉索连接件6h的一端设有连接部，该连接部包括两个具有径向缺口的圈6i，两个圈6i之间具有间隔，两个圈6i的缺口错开布置，在拉索连接件6h的中部位置设有轴孔6j，该轴孔6j用于第二连接轴穿过，以便将拉索连接件6h铰接在支撑块6e上。所述弹簧的活塞杆插入到安装孔6c中螺纹螺合或过盈配合，弹簧1的阀芯从活弹簧1的活塞杆穿过，弹簧1的阀芯控制杆穿过安装孔6c后进入到安装槽6d中后，与拉索连接件6h的另一端部6k形成抵顶。
如图1、图10至图12所示，控制组件7驱动连接组件6使弹簧的阀门形成开启或闭合的，控制组件7与连接组件6连接。所述控制组件包括：驱动杠杆7a、支座7f、拉索7j，驱动杠杆7a的一端设有用于接纳拉索牵引头部的套管7b，驱动杠杆7a设置套管的端面上设有弧形槽7c，在驱动杠杆7a的另一设设有把手7d，该把手7d凸出于驱动杠杆7a的表面，把手7d上设有适配于手指的适配槽，适配槽为三个，分别用于适配食指、中指和无名指。驱动杠杆7a上还设置有一个连接柱7e，该连接柱为空心的连接柱，驱动杠杆7a的一个角部设有缺口，该缺口呈圆弧形。支座7f上设有导向部件7g，支座7f上具有容纳腔体，该导向部件7g为一个圆柱，该圆柱为空心的，支座7f上还设有第一连接柱7h和第二连接柱7i，导向部件7g、第一连接柱7h和第二连接柱7i均位于支座7f的容纳腔体中，且三者的连线构成一个三个角形。所述驱动杠杆7a与支座7f铰接，具体地，支座7f与驱动杠杆7a装配时，导向部件7g穿过弧形槽7c，且导向部件7g间隙配合在驱动杠杆7a上的弧形槽7c中。连接柱7e与第一连接柱7h对应且两者通过螺钉连接，使驱动杠杆7a与支座7f形成铰接，第二连接柱7i与驱动杠杆上的弧形缺口对应。拉索7j的一端与驱动杠杆7a上的套管7b连接,拉索7j的另一端从支座7f上穿出与拉索连接件6h连接。
具体操作时，操作者的手从驱动杠杆7a上的适配槽扶住驱动杠杆7a，对驱动杠杆7a旋 加作用力，驱动杠杆7a绕连接柱7e与第一连接柱7h的铰接点转动，驱动杠杆7a在转动过程中，导向部件7g对驱动杠杆进行导向，驱动杠杆带动拉索7j沿着套管的圆周方向7b进行收放，拉索7j带动拉索连接件6h旋转，拉索连接件6h顶动阀芯控制杆位移，从而使弹簧1的阀门开启，流体在弹簧1的内部形成流动，在通过另一只手或其他物体对弹簧1的活塞杆施加作用力，从而可以使活塞杆升降，进而依次带动弹簧连接件6a和第二套管3升降。
本发明的升降装置不限于上述实施方式，例如所述滚动体除采用圆柱形的滚动体之外，还可以采用滚珠、圆锥滚子等。第一套管2，第二套管，衬套4a，导向套5a还可为菱形或多边形。所述滚动摩擦组件也可以采用另外的结构形式，当在第一套管2上使用滚动摩擦组件时，第一套管2上可以采用图13所述的滚动摩擦组件。第一套管2与滚动摩擦组件的结构优选为：在第一套管2上开设窗口2c，第一套管2的至少两个侧壁面上设有窗口2c，本实施例中，在第一套管2的每个侧壁面上均设有窗口2c。滚动摩擦组件4包括滚动体4b、盖板4k、耳板4m，耳板4m固定在盖板4k上，一块盖板4k上至少固定有两块耳板4m，滚动体4b的两端设有连接轴，该连接轴的两端分别与两个耳板4m连接，将耳板4m插入到窗口4c中，盖板4k盖住窗口4c后，盖板4k通过螺钉或其它方式固定在第一套管2的外壁面上。
本发明可以将上述任意一种实施方式中的升降装置作为腿部应用于家具中。如图14所示，将升降装置作为桌腿应用于办公桌上，该办公桌包括拉板8、横梁9、桌面支架10、桌面11，拉板8固定在两根第一管管2的一侧，拉板8的材料为金属，拉板8上设有的卡口，用于控制升降办公桌的平衡。两根横梁9固定在第二套管3的两侧，使其不晃动；桌面支架10和第二套管3的另一侧固定以支撑桌面11；桌面11和桌面支架12固定；控制组件7固定在桌面的下表面，控制组件7材料优先采用锌合金控制组件7通过拉索7j与弹簧1连接，利用杠杆原理，通过拉索7j控制，实现弹簧5的开关闭合。桌面13的整体形状为矩形，并可制作各种造型。实现桌子的升降。本实施方式中，由于桌腿为两套，因此，拉索7j优先采用Y型的拉索，开关方式为一控二，亦可一控N。升降装置(桌腿)可为3套，形成L型升降办公桌。升降装置升降装置(桌腿)可为1套，形成单住升降办公桌。升降装置升降装置(桌腿)可为4套，形成大型升降办公桌。另外，拉板8和横梁9可为伸缩式。
