根据上述，滑轮12直接与滑轮座11以及阻尼组件2的夹板21转动连接，也即滑轮12、滑轮座11和阻尼组件2的夹板21实现一体连接，保证了阻尼滑轮机构整体连接的稳定性，同时增强了抗冲击强度。
需要说明的是，每个滑轮座11上转动连接的转轴13数量根据滑轮座11沿阻尼管23的伸缩方向的长度而定，滑轮座11沿阻尼管23的伸缩方向的长度越长对应的转轴13的数量越多。
在上述实施例中，将阻尼滑轮机构与推拉门结合说明，推拉门包括两个门扇9和门体外框架，门体外框架包括上轨道、下轨道、左框条和右框条，在本实施例中，每个门扇9对应设置两个阻尼滑轮机构，两个阻尼滑轮机构分别用于同一门扇9的开门阻尼和关门阻尼，滑轮12滑动连接在上轨道上；
以其中一个门扇9进行展开说明，门扇9设在上轨道和下轨道之间，为方便描述，该门扇9上方的两个阻尼滑轮机构分别命名为第一阻尼滑轮机构15和第二阻尼滑轮机构16，第一阻尼滑轮机构15和第二阻尼滑轮机 构16左右设置；
在本实施例中，由于门扇9的顶面长度小于两个阻尼滑轮机构的总长，因此，第二阻尼滑轮机构16整体设置在门扇9的正上方，第一阻尼滑轮机构15的右端设置在门扇9的正上方，左端延伸到门扇9的顶面之外，对应的，上轨道延伸到左框条的外侧壁之外，上轨道延伸到左框条的外侧壁之外的部分用于通过第一阻尼滑轮机构15未处于门扇9正上方的部分，以此来保证门扇9左推时，门扇9的左侧壁能与左框条的内壁贴合；
可以理解的是，如果门扇9的顶面长度足够，也就是门扇9的顶面长度不小于两个阻尼的长度，则两个阻尼滑轮机构都整体设在门扇9的正上方，如此设置使得整体布局更为紧凑，节约安装空间。
上轨道的上方设置两个挡块3，挡块3的底部设有用于与钩拉槽7卡接的凸台，第一阻尼滑轮机构15和第二阻尼滑轮机构16位于两个挡块3之间；
第一阻尼滑轮机构15右端的滑轮座11通过吊杆8与门扇9的顶面连接，第二阻尼滑轮机构16的右端的滑轮座11通过吊杆8与门扇9的顶面连接，较佳的，吊杆8与滑轮座11以及门扇9之间均以可拆卸连接方式进行连接，比如螺纹连接等，在本实施例中，为保证吊杆8与滑轮座11连接的可靠性，连接有吊杆8的滑轮座11上转动连接有两组转轴13，同理，每个转轴13的两端均设置滑轮12；
初始状态下，各活动块22的滑动体分别卡位于对应滑动槽5的卡槽6中，由于卡槽6向下弯曲设置，因此钩拉槽7的开口处于向外且斜向上的状态，此时钩拉槽7的外侧壁的最高点低于挡块3的凸台的底面，钩拉槽7的内壁面的最高点高于挡块3的凸台的底面，第一阻尼滑轮机构15和第二阻尼滑轮机构16的阻尼管23处于伸长状态，拉簧24处于拉长状态，；
以右推门扇9为关门，左推门扇9为开门，参阅图3：
(一)右推门扇9关门，第一阻尼滑轮机构15和第二阻尼滑轮机构16 跟随门扇9向右移动，第二阻尼滑轮机构16右端的活动块22的钩拉槽7的内壁面与右侧挡块3的凸台的侧壁抵接，第二阻尼滑轮机构16右端的活动块22的滑动体从卡槽6中向上脱离，此时，第二阻尼滑轮机构16右端的活动块22的钩拉槽7的开口处于朝上开口的状态，右侧挡块3的凸台完全卡接在第二阻尼滑轮机构16右端的活动块22的钩拉槽7内，门扇9继续向右移动，第二阻尼滑轮机构16右端的活动块22沿着滑动槽5向左滑动，而第二阻尼滑轮机构16的其它部件继续向右运动，第二阻尼滑轮机构16的阻尼管23收缩并对门扇9进行阻尼减速，此时，第二阻尼滑轮机构16的拉簧24也进行收缩，当第二阻尼滑轮机构16的阻尼管23完全收缩，此时门扇9的右侧壁刚好与右框条的内壁贴合，门扇9完成关闭；
(二)左推门扇9开门，第一阻尼滑轮机构15和第二阻尼滑轮机构16跟随门扇9向左移动，第一阻尼滑轮机构15左端的活动块22的钩拉槽7的内壁面与左侧挡块3的凸台的侧壁抵接，第一阻尼滑轮机构15左端的活动块22的滑动体从卡槽6中脱离，此时，第一阻尼滑轮机构15左端的活动块22的钩拉槽7的开口处于朝上开口的状态，左侧挡块3的凸台完全卡接在第一阻尼滑轮机构15左端的活动块22的钩拉槽7内，门扇9继续向左移动，第一阻尼滑轮机构15左端的活动块22沿着滑动槽5向右滑动，而第一阻尼滑轮机构15的其它部件继续向左运动，第一阻尼滑轮机构15的阻尼管23收缩并对门扇9进行阻尼减速，第一阻尼滑轮机构15的拉簧24也进行收缩，当第一阻尼滑轮机构15的阻尼管23完全收缩，此时门扇9的左侧壁刚好与左框条的内壁贴合，门扇9完成打开，此时门扇9的左侧壁刚好与左框条的内壁贴合，门扇9完成打开；
参阅图4，由于门扇9左推开门时右侧挡块3的凸台卡接在第二阻尼滑轮机构16右端的活动块22的钩拉槽7内，所以，门扇9左推打开时，由于第二阻尼滑轮机构16跟着门扇9向左移动，相当于，第二阻尼滑轮机构16右端的活动块22在右侧挡块3的拉动下向右滑动，所以第二阻尼滑轮机 构16的阻尼管23被重新拉伸伸展，最后，第二阻尼滑轮机构16活动块22的滑动体滑动到该滑动槽5对应的卡槽6时，第二阻尼滑轮机构16活动块22跟随滑动体沿着卡槽6向下卡位，至此，第二阻尼滑轮机构16的活动块22的滑动体重新卡位在初始状态时的卡槽6中，第二阻尼滑轮机构16右端的活动块22复位，此时第二阻尼滑轮机构16右端的活动块22的钩拉槽7的开口重新回到向外且斜向上的状态，对应的，第二阻尼滑轮机构16右端的活动块22的钩拉槽7的外侧壁的最高点低于右侧挡块3的凸台的底面，所以右侧挡块3的凸台不在被第二阻尼滑轮机构16右端的活动块22的钩拉槽7卡接，此时门扇9继续向左运动，右侧挡块3的凸台从第二阻尼滑轮机构16右端的活动块22的钩拉槽7内脱离，因此右侧挡块3的凸台不对门扇9的向左运动造成拦挡。
同理，当门扇9重新右推关闭时，第二阻尼滑轮机构16右端的活动块22以同样的方式从卡槽6中脱离，而第一阻尼滑轮机构15左端的活动块22以同样的方式进行复位，同时，左侧挡块3以同样的原理从第一阻尼滑轮机构15左端的活动块22的钩拉槽7中脱离，最终门扇9的右侧壁与右框条的内壁贴合，再次完成门扇9的关闭。
需要说明的是，以上阻尼滑轮机构也可以用于门扇9的底部，具体的，阻尼滑轮机构倒置在门扇9的底部，且阻尼滑轮机构的滑轮12滑动连接在下轨道上，挡块3设在活动块22的下方，滑轮座11同样通过吊杆8与门扇9连接，门扇9底部的阻尼滑轮机构和顶部的阻尼滑轮机构的工作原理一致。
本申请方案所公开的技术手段不仅限于上述实施方式所公开的技术手段，还包括由以上技术特征任意组合所组成的技术方案。应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
