具体实施方式
下面结合附图说明及具体实施方式对本发明进一步说明。
如图1至图7所示，一种伸缩管，包括外管11、内管13和外端塞12，外端塞12设置于外管11的一端部，内管13插接于该端部；内管13能够顺着外管11滑移，即伸长或缩短，从而改变整体的长度。外端塞12包括环体121和滚体122，滚体122设置于环体121，滚体122局部突出于环体121的内表面，同时，滚体122不高于环体121的外表面，使得环体121的外表面与外管11的内壁配合连接；滚体122与内管13的外壁之间为间隙配合，这样，外端塞12与外管11固定不动，外端塞12相对内管13滑动。
本发明的滚体122能够采用两种方式，滚珠或滚针。例如：当内管13的外壁呈弧形时，可选用滚珠配合方式；当内管13的外壁为平面时，可选用滚针的配合方式；当内管13的外壁为平面时，亦能够选用多滚珠并列排列的配合方式。
本发明的环体121具有安装孔1211，滚体122设置于安装孔1211内，因为滚体122与外管11非接触而与内管13可接触，所以滚体122可从环体121的内部放置于安装孔1211内。
本发明的滚体122至少为一个，一个即能够助于内管13相对外端塞12的滚动摩擦，或者均匀分布的多个亦可。
本发明环体121的外表面设置一环阶1212，外管11与环阶1212对接在一起，该环阶1212的设置，便于外端塞12相对外管11的安装固定。
本发明伸缩管包括内端塞14，内端塞14设置于内管13的端部；内端塞14容置于外管11的内部，与内管13同步运动。
本发明内端塞14具有支撑部141，支撑部141处于内管13的外围，且与外管11的内壁配合。该支撑部141具有间隔设置的至少两个配合面，依据外管11内壁的形状，该配合面能够对称设置。或者，内端塞14包括滚体142，滚体142设置于支撑部141；滚体142局部突出于支撑部141的表面，这样，内端塞14与外管11的内壁之间为滑动或滚动摩擦。该滚体142为滚珠或滚针。
本发明增设外端塞12，内管13与外端塞12配合伸缩移动，能够减少外管11与内管13因大小和形状偏差造成的阻力。亦增设内端塞14，内端塞14具有与外管11内壁相配合的支撑面1411，这样外管11与内管13之间具有两组配合连接，使得伸缩更平稳、顺畅，伸缩调节也更省力且噪声亦低。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
