参见图1和图2，本阻尼器可拆卸的铰链为二段力缓冲铰链，包括铰杯11、第一连杆12、第二连杆13、铰臂14、底座15和阻尼器组件，第一连杆12和第二连杆13分别连接于铰杯11与铰臂14之间，铰杯11与铰臂14相互铰接，铰臂14可调节的装配于底座15上。阻尼器组件包括阻尼器A和导向座9，阻尼器A通过导向座9拆卸式装配于铰杯11内。铰链关闭时，第一连杆12端部作用阻尼器A受压收缩；铰链打开时，第一连杆12端部不再作用阻尼器A，阻尼器A自动伸出于导向座9。装配时，导向座9连同阻尼器A直接卡入铰杯11内；本铰链与阻尼器A制作可拆卸结构，在铰链需要阻力时，可以装上阻尼器A，不需要阻力时，可以取出阻尼器A。
进一步说：
为确保阻尼器A可以顺利作用第一连杆12，从而控制整个铰链。参见图16，该阻尼器A包括外壳1，其一端部开口设置，且活动式插设于导向座9内，另一端部封闭设置，且表面设置有斜面105；参见图14，第一连杆12端部设置有凸轮1203，斜面105与凸轮1203表面线接触，且相互作用。铰链关闭时，凸轮1203通过斜面105压缩阻尼器A收缩；铰链打开时，凸轮1203离开斜面105，阻尼器A自动伸出。
为有效控制阻尼器A的伸出幅度，参见图15和图16，外壳1整体呈柱形，截面为非圆形，导向座9对应外壳1的截面设置有截面与其相匹配的导向孔901，导向孔901一端开口，另一端封闭，其内壁上设置有台阶902，外壳1侧壁对应台阶902设置有凸起104。阻尼器A伸出一段距离后，凸起104限位卡扣于台阶902上，可见阻尼器A在限定的范围内移动，确保阻尼器A与导向座9的整体性。
为确保阻尼器A性能的有效性，参见图2，阻尼器A还包括设置于外壳1内的活塞2、活塞杆7和弹簧8；活塞2活动式装配于外壳1内，并将外壳1内部分隔成两腔体；活塞杆7一端插设于活塞2上，另一端外露于外壳1开口端；弹簧8装配于活塞2与外壳1封闭端之间，参见图17，活塞2端部设置有凸台203，弹簧8对应装配于凸台203上，以保证弹簧8的定位。
参见图17，活塞2表面设置有环形的过油槽201，过油槽201侧壁上设有一道过油缺口204和若干过油通孔205，过油缺口204和过油通孔205相互连通，且通过过油缺口204和过油通孔205使活塞2分隔的两腔体相互连通，过油缺口204孔径小于过油通孔205孔径。过油槽201内往复滑动的装配有密封外壳1内壁的封油圈3(参见图18)，封油圈3两侧面分别设有平面301，阻尼器A收缩时，平面301封闭过油通孔205(参见图6)，此时，由于过油缺口204过油量较小，从而实现阻尼器A的缓冲效果；阻尼器A伸出时，平面301打开过油通孔205(参见图10)，由于过油通孔205的过油量较大，阻尼器A正常伸出。
参见图2，外壳1开口端依次固定装配有用于定位的介子4、用于密封外壳1内壁和活塞杆7表面的密封件5，以及用于封闭外壳1开口端的胶盖6。活塞杆7依次穿过胶盖6、密封件5和介子4，最后插设于活塞2上的盲孔202内。参见图16，外壳1内设置有活塞腔101和密封腔102，以及卡槽103，活塞2和弹簧8装配于活塞腔101内，介子4和密封件5装配于密封腔102内，胶盖6表面凸起有环形槽601(参见图19)，且对应卡入卡槽103内。其中，介子4为圆环形的金属块；密封件5为截面呈Y形的密封圈，其外表面密封密封腔102的内壁，内侧则密封活塞杆7的表面，确保密封性。
参见图12和图15，导向座9侧面设置有凸点904，铰杯11内壁对应凸点904设置有卡孔1104，凸点904配合卡扣于卡孔1104内。导向座9内的导向孔901封闭端上设置有一通孔903，活塞杆7的外露端插设于通孔903内，对活塞杆7有定位作用。
阻尼器A的装配过程如下：将弹簧8放入外壳1的活塞腔101中，往活塞腔101中加入阻尼油，把封油圈3套入活塞2的过油槽201中，再将活塞杆7插入活塞2的盲孔202中，进行紧配，然后将装配好封油圈3、活塞杆7的活塞组件插入活塞腔101中，弹簧8对应套在活塞2的凸台203上。随后，把介子4、密封件5和胶盖6依次分别套入活塞杆7上，将胶盖6上的环形槽601压入卡槽103中，紧扣在外壳1内。最后，将组装好的阻尼器A插入导向座9的导向孔901内，活塞杆7端部对应插入通孔903中，外壳1上的凸起104越过导向座9内的台阶902，防止阻尼器A掉出，而且阻尼器A有一定的活动范围。阻尼器A在弹簧8的作用下，保持伸出状态。
阻尼器A工作原理：当阻尼器A受压时，过油圈3相对压住活塞2上的过油通孔205，造成阻尼油只能从过油缺口204流过，从而产生阻力，释放压力后，在弹簧8的作用下，阻尼器A伸出，过油圈3离开活塞2上的过油缺口204，使过油缺口204与过油通孔205连通，形成大的通道，阻尼油能快速通过活塞2，阻力消失。
参见图1，第一连杆12带凸轮1203的端部置于铰杯11内，并通过U型轴16与铰杯11铰接，另一端设置弧形凹槽1204装配扭簧21(参见图13)，并通过一铆钉17共同铰链于铰臂14上。U型轴16同时铰接第二连杆12一端部于铰杯11内，另一端装配有短钉18，并通过另一铆钉17铰接于铰臂14上，扭簧21中间延长部分压在铰臂14上，两端延长部分压在短钉18上。
铰臂14通过调节螺钉19和锁紧螺钉20可调节的装配于底座15上，底座15固定于柜体上，铰杯11固定于门体上。
铰链的装配过程如下：参见图1，将短钉18插入第二连杆13的轴孔1303中，进行活动轴连接；将一铆钉17同时穿入铰臂14的铆孔1401、第一连杆12的铆孔1202和扭簧21的铆孔2101，进行活动轴连接；将另一铆钉17同时穿入铰臂14的铆孔1402和第二连杆13的铆孔1302中，进行活动轴连接。其中，扭簧21中间延长部分压在铰臂14上，两端延长部分压在短钉18上；U型轴16的一端同时穿入铰杯11的轴孔1101和第一连杆12的轴孔1201，进行活动轴连接；U型轴16的另一端同时穿入铰杯11的轴孔1102和第二连杆13的轴孔1301中，进行活动轴连接。铰杯11、第一连杆12、第二连杆13和铰臂14形成一个四连杆机构，在扭簧21的作用下，可以自动闭门。将调节螺钉19锁入铰臂14的螺纹调节孔1403中，将底座15装嵌入铰臂14内，将底座15的U型缺口1502卡入调节螺钉19的调节槽1901中；将锁紧螺钉20穿过铰臂14上的缺口1404，锁入底座15上的螺纹孔1501中， 实现铰臂14和底座15连接在一起，且可进行调节。将阻尼器组件卡入铰杯11内，阻尼器组件的凸点904卡入铰杯11的卡孔1104中，进行固定。
关闭铰链一定角度后，在扭簧21的作用下，铰链开始自动闭门，铰链自动闭门一定角度，第一连杆12上的凸轮1203开始压缩铰杯11中的阻尼器组件的斜面105，铰链缓慢闭门直到铰链完全关闭；打开铰链，第一连杆12上的凸轮1203离开阻尼器组件上的斜面105，阻尼器A在弹簧8的作用下，阻尼器A伸出到位。
