Description

伸缩管缓冲结构 技术领域
本申请涉及一种伸缩梯子，尤其涉及一种伸缩管缓冲结构。
背景技术
现有的伸缩梯子包括若干梯柱及横杆，通过将多节梯柱相互滑动套接，实现梯子的伸缩功能。而在某些场合，通常需要将伸缩梯子的顶端固定于墙面或横梁上面，因此，在使用时，是将伸缩梯子的最下端的一节梯柱向下拉出，通过下端的梯柱带动上一节梯柱，从而逐步将整个梯子向下展开；在不使用时，先将最下端的一节梯柱向上推，使上一节梯柱缩入于下一节梯柱内，依此顺序向上收缩，从而将整个梯子收起。然而，在上述的展开或收折过程中，由于梯柱上的内管与外管之间没有缓冲，因此，下一节梯柱相对上一节梯柱向下滑出时，在拉力及重力的作用下，极有可能会因为滑动速度过快而逼使操作者的身体发生倾斜，进而产生安全性问题，因此，现有挂于墙面或横梁上面的伸缩梯子的内管与外管之间缓冲效果不好，在安全使用问题上存在不足。
申请内容
本申请的目的在于提供一种结构简单，缓冲效果好，提高使用安全性的伸缩管缓冲结构。
为了实现上述目的，本申请提供的伸缩管缓冲结构包括内管及外管，所述内管滑动地套接于所述外管内，所述伸缩管缓冲结构还包括缓冲片及挡位片，所述挡位片固定于所述内管的一端，所述挡位片与所述内管的端面之间形成一容置槽，所述缓冲片设置于所述挡位片上且位于靠近所述容置槽的一侧，所述缓冲片的边缘与所述外管的内侧壁抵触，以使所述内管在缩入所述外管时，所 述缓冲片的边缘翻入所述容置槽中，在伸出所述外管时，所述缓冲片的边缘滑动地抵压于所述外管的内侧壁，实现缓冲。
与现有技术相比，由于本申请通过在所述内管的一端设置挡位片，使使所述挡位片与所述内管的端面之间形成一容置槽，并在所述挡位片靠近所述容置槽的一侧设置缓冲片，从而可使所述缓冲片的边缘能与所述外管的内侧壁抵触，达到在所述伸缩梯子收缩时，所述缓冲片向上翻减少摩擦力，在所述梯子展开时，所述缓冲片受到所述挡位片的阻挡而保持与所述外管的内侧壁滑动抵触的目的，进而在展开时实现缓冲，其结构简单，缓冲效果好，防止伸缩梯子展开时因梯柱过快地向下滑出而逼使操作者的身体发生倾斜的安全性问题，有效提高伸缩梯子使用的安全性。
较佳地，所述伸缩管缓冲结构还包括导向套，所述导向套固定于所述内管的端面上。所述导向套可以在所述内管相对所述外管滑动时对所述内管进行导向。
较佳地，所述缓冲片为硅胶片。硅胶材料具有弹性可变形且摩擦系数较大，在使用时能提高较大的摩擦力，提高缓冲效果。
较佳地，所述容置槽环绕所述内管。
较佳地，所述内管及所述外管为三角管。
附图说明

图2是本申请伸缩管缓冲结构的结构图。
图3是本申请伸缩管缓冲结构的在梯子拉伸时的剖面状态图。
图4是本申请伸缩管缓冲结构的在梯子收缩时的剖面状态图。
具体实施方式
为详细说明本申请的技术内容、构造特征、所实现的效果，以下结合实施方式并配合附图详予说明。
如图2及图3所示，本申请伸缩管缓冲结构100包括内管1及外管2，所述 内管1滑动地套接于所述外管2内；所述内管1及所述外管2为三角管。所述伸缩管缓冲结构100还包括缓冲片3、挡位片4及导向套5；所述缓冲片3、挡位片4及导向套5的横截面与所述内管1的横截面对应。所述挡位片4通过螺丝7固定于所述内管1的一端，所述挡位片4与所述内管1的端面之间形成一环绕所述内管1的容置槽6；所述导向套5固定于所述内管1的端面上且位于靠近所述容置槽6的一侧，以使所述导向套5与所述档位片正对，中间相隔的容置槽6；所述导向套5可以在所述内管1相对所述外管2滑动时对所述内管1进行导向。所述缓冲片3设置于所述挡位片4上且位于靠近所述容置槽6的一侧，所述缓冲片3的边缘与所述外管2的内侧壁抵触，以使所述内管1在缩入所述外管2时，所述缓冲片3的边缘翻入所述容置槽6中，在伸出所述外管2时，所述缓冲片3的边缘滑动地抵压于所述外管2的内侧壁，实现缓冲。
所述缓冲片3为硅胶片。硅胶材料具有弹性可变形且摩擦系数较大，在使用时能提高较大的摩擦力，提高缓冲效果。
结合图1及图4所示，伸缩梯子200在展开时，伸缩梯子200的上端固定于横梁300上，伸缩梯子200的最下方的一节梯柱首先向下伸出，因此，所述外管2相对所述内管1向下滑动，在滑动的开始时，所述缓冲片3的边缘与所述外管2的内侧壁滑动抵触，并随所述外管2滑动的趋势而向下发生变形，然而，由于受到下方的所述挡位片4的阻挡作用，所述缓冲片3的边缘只能与所述外管2的内侧壁接触并产生更大的摩擦阻力，因此，所述缓冲片3阻碍所述外管2向下滑动，达到对所述外管2进行缓冲的作用。伸缩梯子200在收缩时，最下方的一节样子柱是向上收缩的，因此，所述外管2相对所述内管1向上滑动，在滑动的开始时，所述缓冲片3的边缘与所述外管2的内侧壁滑动抵触，并随所述外管2滑动的趋势而向上发生变形，然而，由于所述缓冲片3的上方是容置槽6，因此所述缓冲片3的边缘可顺势向上翻入所述容置槽6中，从而减少与所述外管2的内侧壁接触的压力，进而减少摩擦阻力，使所述外管2快速顺利地向上与所述内管1套接，实现收折。
与现有技术相比，由于本申请通过在所述内管1的一端设置挡位片4，使使所述挡位片4与所述内管1的端面之间形成一容置槽6，并在所述挡位片4靠近 所述容置槽6的一侧设置缓冲片3，从而可使所述缓冲片3的边缘能与所述外管2的内侧壁抵触，达到在所述伸缩梯子200收缩时，所述缓冲片3向上翻减少摩擦力，在所述梯子展开时，所述缓冲片3受到所述挡位片4的阻挡而保持与所述外管2的内侧壁滑动抵触的目的，进而在展开时实现缓冲，其结构简单，缓冲效果好，防止伸缩梯子200展开时因梯柱过快地向下滑出而逼使操作者的身体发生倾斜的安全性问题，有效提高伸缩梯子200使用的安全性。
以上所揭露的仅为本申请的较佳实例而已，当然不能以此来限定本申请之权利范围，因此依本申请申请专利范围所作的等同变化，仍属于本申请所涵盖的范围。
