Abstract

本实用新型公开了一种伸缩管，它由壁内部带有导槽外管和可沿外管轴向伸缩的内管组成，所述的外管壁内部带有用于固定内管活动的导槽，并在相应位置开孔形成扣孔，用于内管的固定；同时在外管的开孔处安置一个滑环，滑环能在被固定环限定的范围内滑动；在内管顶部安置有一个能够锁住外管孔的凸扣，该凸扣用弹性材料固定，能在外管内自由运动。通过简单的推拉内管运动即能实现管的伸缩，结构简单，操作方便，能在伸缩吊灯或晾衣杆等一系列需要伸缩的地方应用。

Description

一种新型伸缩管
技术领域
本新型伸缩结构可以用于需要将管伸缩的场合，尤其是对于实现竖直方向的伸缩。  
背景技术
传统的伸缩方式不能够实现竖直方向的既可伸缩又可定位。  
发明内容
为了解决现有技术的不足，本实用新型的目的是提供一种改进的伸缩管。这种改进的伸缩管结构简单，巧妙，具有良好的伸缩与固定功能。 
为了达到上述目的，本实用新型采用的技术方案是：一种伸缩管，它由壁内部带有导槽的外管和可沿外管轴向移动的内管组成，所述的外管壁内部带有用于固定内管活动的导槽，并在相应位置开孔形成扣孔，用于内管的固定；同时在外管的开孔处安置一个滑环，并在扣孔内壁的上下两端各安置一个固定环，使滑环能在被固定环限定的一定范围内滑动；在内管顶部安置有一个能够锁住扣孔的凸扣，该凸扣用弹性材料固定，能在外管内自由运动。 
附图说明
图1是本实用新型的伸缩管处于伸缩固定的状态图； 
图2是本实用新型的伸缩管其凸扣处于最高点的状态图；
图3是本实用新型的伸缩管处于自由状态图。
具体实施方式
现在参照附图并结合实施例，对本实用新型做详细的说明和解释，附图和实施例都是对实用新型的解释，而不是对本实用新型的限定。 
如图1至3所示，本实用新型的实施例公开了一种伸缩管，其可用在竖直方向的伸缩上，也可以用于其他的需要将管伸长或收缩的场合，它由壁内部带有导槽的外管1和可沿外管轴向移动的内管2组成，所述的外管壁内部带有用于固定内管活动的导槽，并在相应位置开孔形成扣孔，用于内管的固定；同时在外管的开孔处安置一个滑环5，并在扣孔内壁的上下两端各安置一个固定环4，滑环能在被固定环4限定的范围内滑动；在内管顶部安置有一个能够锁住扣孔的凸扣3，该凸扣用弹性材料固定，能在外管内自由运动。 
采用了上述的结构后，在需要伸长的时候，只需推动内管2，凸扣3向上运动，同时顶住滑环5至最顶端，然后向下拉动内管2，滑环5由于凸扣3的摩擦力向下滑动至孔处并挡住扣孔，使内管凸扣3顺利滑下至下一扣孔处固定，实现管的伸长；在需要缩短时，只需利用凸扣3的平滑性向上推动内管至下一扣孔即可。 

Claims (2)

1.一种新型伸缩管，它由壁内部带有导槽外管和可沿外管轴向伸缩的内管组成，所述的外管壁内部带有用于固定内管活动的导槽，并在相应位置开孔形成扣孔，用于内管的固定；同时在外管的开孔处安置一个滑环，滑环能在被固定环限定的范围内滑动；在内管顶部安置有一个能够锁住外管孔的凸扣，该凸扣用弹性材料固定，能在外管内自由运动。
2.根据权利要求1所述的新型伸缩管，其特征在于，在外管的开孔处安置一个滑环，并在扣孔内壁的上下两端各安置一个固定环，使滑环能在被固定环限定的范围内滑动。
