实施例：
在本实施例中，提供一种医疗设备，医疗设备上设置摇臂机构，如图1-4所示，摇臂机构包括第一摇臂002、第二摇臂003和阻尼结构001，其中，阻尼结构001包括：转轴1、第一基座2、摩擦件3、第二基座4、第一调节组件5及第二调节组件6，转轴1的一端具有第一限位结构11，第一基座2、摩擦件3和第二基座4依次套设于转轴1，第一基座2与第一限位结构11相连，第一限位结构11用于阻止第一基座2从转轴1的对应端脱离，第二基座4和摩擦件3均与转轴1转动装配，第一调节组件5装配于转轴1且位于第二基座4的远离第一基座2侧，第一调节组件5用于将第二基座4沿着转轴1向靠近第一基座2的方向挤压以使摩擦件3的两端面分别贴紧第一基座2和第二基座4，第二调节组件6包绕在摩擦件3的外侧，第二调节组件6用于对摩擦件3施加朝向转轴1的径向力使摩擦件3的内壁面贴紧转轴1的外壁面，第一摇臂002的一端固定连接于第一基座2，第二摇臂003固定连接于第二基座4。
摇臂机构中装配了阻尼结构001之后，通过调节第一调节组件5可以调节第二基座4与第一基座2之间的距离，以调节摩擦件3与第一基座2及第二基座4在转轴1轴向方向上的压力，从而实现摩擦件3的端面与第一基座2及第二基座4之间的摩擦力的调节，通过调节第二调节组件6可以调节摩擦件3与转轴1之间的摩擦力，在第一调节组件5和第二调节组件6的配合下，实现了对第一基座2和第二基座4之间阻尼大小的调节，将第一基座2和第二基座4之间的阻尼大小调节合适后，可以使装配了该阻尼结构001的摇臂机构中的摇臂保持特定的角度，并且在外力的作用下可以调节摇臂机构中摇臂的角度，调节完角度后阻尼结构能使摇臂机构的摇臂保持在该角度，无需每次调节角度时均对摇臂机构的关节进行松开和锁紧的操作，调节角度时更加快捷高效。
第一限位结构11包括抵顶凸缘111和用于阻止第一基座2绕转轴1转动的第一限位面112，抵顶凸缘111从转轴1端部周缘径向朝外延伸形成，第一限位面112位于转轴1的轴身外壁，第一基座2开设限位孔21，限位孔21的内壁包括第二限位面211，转轴1穿设于限位孔21，第一限位面112与第二限位面211对应匹配，抵顶凸缘111抵顶于第一基座2的一侧。具体的，在本实施例中，转轴1的轴身外壁具有两个第一限位面112，两第一限位面112均为平面且平行于转轴1的轴线，两第一限位面112相对设置，且两第一限位面112均从转轴1的靠近抵顶凸缘111端延伸至远离抵顶凸缘111端，对应的，限位孔21的内壁具有两第二限位面211，在转轴1穿设于限位孔21内时，第一限位面112与对应的第二限位面211对应，在转动第一基座2的过程中，第一限位面112和第二限位面211会相互抵顶，从而阻止第一基座2绕转轴1转动，抵顶凸缘111与转轴1的轴身一体成型。在一些实施例中，转轴1上可以设置一个、三个、四个等的第一限位面112，且第一限位面112也可以是曲面。在一些实施例中，转轴1可以由分离的轴体和抵顶凸缘111连接形成，具体的，抵顶凸缘111为片状，且抵顶凸缘111的直径大于转轴1的直径，抵顶凸缘111可以由螺钉固定在轴体上从而形成转轴1，在这种设置方式下，第一限位面112无需在转轴1的整个轴身进行延伸，只需要保证第一限位面112在转轴1轴向上的长度大于第一基座2的厚度即可，采用这种设置方式能将第一基座2从转轴1的轴身靠近第一限位结构11端与转轴1轴身装配后再将抵顶凸缘111与轴身固定，这种方式可以避免削减轴身的材料，从而提高转轴1轴身的强度。在一些实施例中，转轴1的轴身上可以不设置第一限位面112，即第一基座2能绕转轴1转动。
第一调节组件5包括调节螺母51，转轴1的远离抵顶凸缘111的一端的外壁设置与调节螺母51匹配的外螺纹，调节螺母51与转轴1螺纹装配。第一调节组件5还包括垫片52，垫片52套设于转轴1且位于调节螺母51和第二基座4之间。转动调节螺母51，可使调节螺母51沿着转轴1朝靠近或远离第一限位结构11的方向移动，从而带动第二基座4将摩擦件3夹紧或放松，以调节摩擦件3端面与第一基座2和第二基座4的摩擦力；垫片52的数量可以根据实际情况设置，例如一片、两片、三片、四片、五片等，垫片52具有与转轴1适配的轴孔，从而避免绕转轴1转动，在摩擦件3和第二基座4之间也可以设置垫片52。
第二调节组件6包括调节件61和调节螺钉62，调节件61具有抵压面611，调节件61包绕在摩擦件3的外侧，抵压面611抵顶在摩擦件3的外侧，调节螺钉62连接于调节件61，调节螺钉62用于调节调节件61自身的张力。调节件61为开环，调节件61的两端分别朝外延伸形成调节凸起612，两调节凸起612分别开设调节孔，调节螺钉62从一调节凸起612的调节孔穿过并与另一调节凸起612的调节孔螺纹装配。通过转动调节螺钉62，可以使调节件61的两端相互靠近或相互远离，从而改变调节件61的张力，即：使调节件61拉紧收缩或放松舒张，使得抵压面611抵顶摩擦件3外侧的力改变，进而使摩擦件3收缩或放松以改变摩擦件3的内壁与转轴1外壁之间的压力，从而调剂摩擦件3与转轴1之间的摩擦力，通过摩擦件3两端面及其内壁面的摩擦力，可以使阻尼结构001获得更大的阻尼，且可以通过两种方式调节阻尼大小，使得调节更加灵活。在本实施例中，摩擦件3采用弹性材料制成，摩擦件3开设有轴孔，轴孔与转轴1的最大直径方向匹配，因此，摩擦件3被挤压时能与转轴1的外壁面贴紧。
在本实施例中，为了使调节件61对摩擦件3的压力调节更加灵敏有效，调节件61具有从抵压面611凹陷形成的变形槽613。在本实施例中，调节件61上具有一个变形槽613，在其他实施例中，调节件61上可以具有两个、三个、四个等的变形槽613。在本实施例中，为了获得更好的阻尼调节效果，第一基座2和调节件61通过螺钉固定连接，一方面可以使调节件61更加稳定可靠，另一方面，调节件61与第二基座4之间接触时，也可以获得摩擦力，从而进一步获得阻尼调节效果。
在本实施例中，第一基座2和第二基座4分别开设第一定位孔和第二定位孔，具体数量为四个，在其他实施例中，第一定位孔和第二定位孔的数量可以是两个、三个、五个、六个等，第一摇臂002和第二摇臂003通过螺钉分别固定在第一基座2和第二基座4上，螺钉分别与第一定位孔和第二定位孔连接，第一摇臂002和第二摇臂003的端部均具有容置槽，第一基座2和第二基座4分别置于对应摇臂的容置槽内。
在本实施例中，摇臂机构包括一第一摇臂002和一第二摇臂003，即摇臂机构的摇臂之间具有一个关节，关节处安装阻尼结构001，第二摇臂002通过阻尼结构001转动装配在医疗设备上，第一摇臂002和第二摇臂003的远离关节端均可以设置阻尼结构001，以安装用于固定医疗器件的装配结构。在其他实施例中，摇臂机构可以包括两个、三个、四个等的第一摇臂002和第二摇臂003，第一摇臂002和第二摇臂003相连，在此并不限定其连接顺序，各相邻的摇臂之间均有阻尼结构001相连，各阻尼结构001中的转轴1的延伸线可以相互平行或者具有夹角，在全部阻尼结构001中的转轴1的延伸线相互平行时，摇臂机构中的各摇臂仅在一个平面内运动，当阻尼结构001中的转轴1的延长线之间具有夹角时，可以使摇臂机构中的部分摇臂在空间内运动，夹角可以是30°、45°、60°、90°等，在实际设置中可以优选90°夹角。
在本实施例中，摇臂机构还包括连接组件004，连接组件004包括滑动座041、固定块042和夹紧件043，固定块042通过螺钉固定于滑动座041，固定块042和滑动座041之间形成夹持口，夹持口与第一摇臂002匹配，第一摇臂002滑动装配于夹持口内，夹紧件043铰接在滑动座041上，夹紧件043的自由端具有卡钩0431，滑动座041的对应位置具有卡槽0411，滑动座041的与夹紧件043对应处设置定位结构0412，定位结构0412为多个定位槽，通过定位槽和夹紧件043的配合，可以将医用的输液管道进行定位，滑动座041的底部可以固定吊钩，从而吊挂医用器具。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
