Description

吸尘器的伸缩管结构 技术领域
本发明涉及吸尘器技术领域，具体涉及一种吸尘器的伸缩管结构。
背景技术
现有的吸尘器的伸缩管的内管与外管一般通过密封圈密封，密封圈在安装时，需要将密封圈产生较大的形变挤进放置槽，这种装配过程易造成密封圈损伤，影响内管与外管的密封质量。
发明内容
本发明的目的在于提供一种吸尘器的伸缩管结构，其用于密封内管与外管的密封圈在组装时不会受到损伤，保证组装后的密封圈的质量。
为实现上述目的，本发明提供如下技术方案：
一种吸尘器的伸缩管结构，包括内管和外管，内管插在外管中，内管与外管滑动配合，外管内壁的端部设有环形置放槽，环形置放槽内安放有密封外管与内管的密封圈，密封圈包括第一半圈和第二半圈，第一半圈的两端分别设有密封插口，第二半圈的两端分别设有密封插条，密封插条分别插装在密封插口内。
优选地，密封插条过盈插装在密封插口内。
优选地，密封插条包括钢丝和包裹在钢丝外侧的硅胶条。
本发明的工作原理为：组装密封圈时，先将第一半圈安放进置放槽，再将第二半圈安放进置放槽，将第二半圈的密封插条插入第一半圈的密封插口内，完成密封圈的安放；整个安放过程，密封圈不存在大的形变，有效保证了密封圈的质量。密封插条采用钢丝和包裹在钢丝外侧的硅胶条的设置，钢丝可插入第一半圈，方便第一半圈和第二半圈的连接，同时又保证了密封效果。
本发明的有益效果为：其用于密封内管与外管的密封圈在组装时不会受到损伤，保证组装后的密封圈的质量。
