本发明提出一种密封装置100，用于一些需要具有防水、防烟尘功能的机械设备，现有技术中的宝塔结构的密封装置，该密封装置100具有多层，且每层的内径沿密封装置100远离安装板110的方向逐渐减小，且远离安装板110的一端密封设置，且每一层均带有不同线径的标识。使用时，操作人员可根据待密封件200的直径所对应的线径去剪宝塔的线径标识圈，操作繁琐，且一旦操作人员剪错路径或没有按照规定操作，就极易导致宝塔结构失去密封作用。而本方案相较于现有技术中的密封装置，则可以有效规避这一缺陷。
在本发明实施例中，如图1至图5所示，密封装置100包括安装板110和设于安装板110上的多个第一密封筒120，安装板110上开设有供待密封件200穿设的通孔111。多个第一密封筒120间隔且相互嵌套设置于安装板110的一侧，第一密封筒120上开设有第一开口与第二开口121，第一开口连20接通孔111的外周缘，第二开口121与待密封件200的表面抵接，以密封待密封件200的外周缘。
第一密封筒120具有第一开口与第二开口121，且第一开口连接通孔111的外周缘，且待密封件200穿设于通孔111，即待密封件200穿设于第一开口与第二开口121，且第二开口121与待密封件200的表面抵接，以密封待密封件200的外周缘，第二开口121围合并封堵与待密封件200的外周缘，从而形成密封作用。且多个第一密封筒120间隔且相互嵌套设置，使得多个第二开口121均能够压紧待密封件200的周缘，从而增强密封效果。且多个第一密封筒120间隔且相互嵌套设置，暂设第一密封筒120的数量有两个，则两个第一密封筒120相互嵌套设置，则必有一个位于内侧， 另一个位于外侧。外侧第一密封筒120上的第一开口设于内侧第一密封筒120上的第一开口处的外周缘，待密封件200从通孔穿过，首先经过内侧第一密封筒120上的第二开口121，而后经过外侧第一密封筒120上的第二开口121。即外侧第一密封筒120对内侧第一密封筒120形成包围结构，使得外侧第一密封筒120能够对内侧第一密封筒120起到防护作用，降低内侧第一密封筒120受到紫外线作用老化的可能，从而增强密封装置100的使用寿命。当然，在其它实施例中，第一密封筒120的数量也可以多于两个，多个第一密封筒120也采用相互嵌套的形式安装于安装板110的同一侧。
本实施例中，第一密封筒120与安装板110一体成型，不仅能够减少第一密封筒120与安装板110的安装工序，而且增强了第一密封筒120与安装板110的连接强度，且增强该密封装置100的密封强度。
本发明技术方案通过于安装板110上设置供待密封件200穿设的通孔111和第一密封筒120，第一密封筒120上开设有第一开口与第二开口121，第一开口连接通孔111的外周缘，第二开口121与待密封件200的表面抵接，以密封待密封件200的外周缘，第二开口121围合并封堵与待密封件200的外周缘，从而形成密封作用。且多个第一密封筒120间隔且相互嵌套设置，使得多个第二开口121均能够对待密封件200的起到密封作用，从而增强密封效果。且该密封装置100能够避免使用现有技术中的宝塔结构的密封装置，从而降低操作人员因操作不慎剪错路径或没有按照规定操作，致使密封装置100失效的情况，方便操作人员操作。
进一步的，第二开口121的口径小于通孔111的孔径，以压紧待密封件200的外周缘。具体地，第二开口121的口径小于通孔111的孔径，使得待密封件200穿设于第二开口121时，第二开口121能够对待密封件200产生挤压作用，从而压紧待密封件200的周缘，进一步提高第一密封筒120的密封效果。
更进一步的，第一密封筒120的内径由第一开口向第二开口121逐渐变小设置。且第一密封筒120为弹性材料。具体地，第一密封筒120的内径由第一开口向第二开口121逐渐变小设置，即第一密封筒120的截面形状为梯形，且第一密封筒120为弹性材料。待密封件200利用第一密封筒 120的弹性插设于第一密封筒120的内径，且因第一密封筒120的弹性，使得该密封装置100能够容纳一定直径范围的待密封件200，从而适应不同直径的待密封件200。
本实施例中，第一密封筒120的截面形状为梯形，当然，在其它实施例中，第一密封筒120也可以为圆筒状。本实施例中，第一密封筒120为弹性材料，该弹性材料可以为橡胶、塑料等具有一定弹性的材料。
在另一实施例中，结合参照图4和图5，密封装置100还包括第二密封筒130，第二密封筒130围合于通孔111的外周缘，并与第一密封筒120分设于安装板110的相对两侧。具体地，第二密封筒130与第一密封筒120分设于安装板110的相对两侧，第二密封筒130也具有密封作用，从而进一步增强密封装置100的密封强度。
其中，第二密封筒130的个数可以为一个，也可以为多个，且多个第二密封筒130间隔且相互嵌套设置。第二密封筒130也为弹性材料，该弹性材料可以为橡胶、塑料等具有一定弹性的材料。
为增强安装板110的结构强度，在一实施例中，结合参照图1至图5，安装板110包括骨架层及设于骨架层的面料层，第一密封筒120与面料层一体成型。该骨架层可以为金属材料，从而增强安装板110的结构强度。面料层包裹于骨架层，且第一密封筒120与面料层一体成型，从而增强安装板110的结构稳定性。面料层可以为塑料材料，故骨架层可以以金属嵌件的形式与面料层一体注塑成型于安装板110。
参照图3，在一实施例中，通孔111或第一密封筒120或第二密封筒13020上设有封堵部140，以封堵通孔111或第一密封筒120的内孔或第二密封筒130的内孔。具体地，封堵部140可以封堵通孔111或第一密封筒120的内孔或第二密封筒130的内孔。使得该密封装置100不用时也处于密封状态。其中，该封堵部140一体成型于安装板110，不仅能够减少封堵部140与安装板110的安装工序，而且增强了封堵部140与安装板110的连接强度，提高安装板110的结构稳定性，且进一步增强该密封装置100的密封强度。
进一步的，封堵部140上设有指示标签141，用于指示第一密封筒120所能密封的待密封件200的直径范围。该指示标签141能够显示允许穿设 的待密封件200的直径范围，从而指示使用者能够选择合适尺寸的待密封件200密封。从而方便操作人员操作，提高安装效率。本实施例中，指示标签141设于封堵部140，当然，在其它实施例中，该指示标签141也可以设置于安装板110上，且位于通孔111或密封装置100的附近。
更进一步的，封堵部140上设有引导凸部142。从而增大操作人员与封堵部140的接触面积，使得操作人员通过拉动引导凸部142进而撕开封堵部140，从而方便操作人员操作。
另一实施例中，封堵部140的周缘处的厚度小于封堵部140轴心处的厚度。因封堵部140的周缘处的厚度小于封堵部140轴心处的厚度，从而使得封堵部140的周缘处比封堵部140的轴心处更易撕开，从而方便操作人员操作。因封堵部140的厚度较小，也可利用待密封件200穿设于密封装置100时的冲击力来穿破封堵部140。
为满足对多个直径不同的待密封件200的密封，在一实施例中，安装板110上设有多个通孔111，且多个通孔111中的至少两个的直径不相等，且每一通孔111的周缘均设有多个相互间隔且相互嵌套设置的第一密封筒120。具体地，安装板110上设有多个供待密封件200穿设的通孔111，从而使得该安装板110能够同时满足多个待密封件200的密封。且多个通孔111中的至少两个的直径不相等，从而满足不同直径的待密封件200的密封，进一步提高该密封装置100的实用性。
本发明还提出一种机械设备，该机械设备包括待密封件200和密封装置100，该密封装置100的具体结构参照上述实施例，由于本机械设备采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。其中，待密封件200穿设于密封装置100，密封装置100密封于待密封件200的周缘。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
