本申请提出一种拉伸杆，适用于支架等，此处不限。
参照图1至图4，在本申请一实施例中，该拉伸杆包括第一拉杆10、第二拉杆20，第二拉杆20可活动地插设于第一拉杆10；弹性组件30包括至少一个弹性件31和摩擦块32，弹性件31具有相对的第一端和第二端，弹性件31的第一端安装于第二拉杆20插入于第一拉杆10内的一端上，弹性件31的第二端通过摩擦块32与第一拉杆10的内壁连接。
本实施例中，第一拉杆10和第二拉杆20均可呈中空长杆状设置，其材质均可为塑胶或金属等，此处不限。第二拉杆20的直径可略小于第一拉杆10的直径，以方便第二拉杆20活动插设于第一拉杆10中。
本实施例中，弹性件31可为压缩弹簧或塑胶弹性体等具有一定弹性的部件，摩擦块32与第一拉杆10的抵接处可与其内壁做仿形设计，做成弧度相同的弧形结构，以方便第二拉杆20相对第一拉杆10滑动拉伸，此处对弹性组件30的结构不做具体限定。
在本申请的技术方案中，该拉伸杆包括第一拉杆10、第二拉杆20和弹性组件30，拉伸杆包括第一拉杆10、第二拉杆20，第二拉杆20可活动地插设于第一拉杆10；弹性组件30包括至少一个弹性件31和摩擦块32，弹性件31具有相对的第一端和第二端，弹性件31的第一端安装于第二拉杆20插入于第一拉杆10内的一端上，弹性件31的第二端通过摩擦块32与第一拉杆10的内壁连接。如此，弹性组件30设于第一拉杆10与第二拉杆20之间，避免了第一拉杆10与第二拉杆20产生直接摩擦，减小了磨损，且弹性件31伸缩过程中可通过挤压摩擦块32向第一拉杆10提供均匀的挤压力，使得第一拉杆10与第二拉杆20之间的摩擦力得以均匀分散，进而提升了拉伸杆的稳定性，并延长了使用寿命。
此外，在一些实施例中，需要在拉杆连接处进行走线布线时，弹性件31上可开设有供线缆穿过的走线通道31a，第二拉杆20上对应走线通道31a的位置开设有过线孔20a。可以理解，由于弹性件31设有走线通道31a，第二拉杆20设有过线孔20a，使得电源线等线缆的走线更为方便。
本实施例中，走线通道31a可为压缩弹簧自身中空的结构形成，或压缩弹簧与第二拉杆20的中空的弹性件卡柱共同形成，或开设于塑胶弹性体中部的通孔。
请参考图2、图4至图6，在一实施例中，第二拉杆20可包括拉杆本体21，拉杆本体21插入端的至少一侧设有沉槽，沉槽上开设有容置孔21a，容置孔21a的数量与弹性件31的数量相同，弹性件31的第一端容置于容置孔21a内；或者，弹性组件30还包括支撑片33，沉槽内设有限位孔，支撑片33设于沉槽且支撑片设有卡入于限位孔的限位臂331，限位臂331上设有供所述弹性件31的第一端容置的容置槽。如此，可在提升拉伸杆的稳定性，延长其使用寿命的同时，进一步地提升了组装的便利性。
其中，容置孔21a的底壁上可开设过线孔20a，以供电源线等线缆穿过。
在一些其他实施例中，如图4所示，为了保证更好的拉伸顺畅度，进一 步地提升拉伸杆的使用寿命，第二拉杆20可包括拉杆本体21和支撑座22，支撑座22安装于拉杆本体21插入于第一拉杆10内的一端上，支撑座22上设有安装孔22a，安装孔22a的数量与弹性件31的数量相同，弹性件31的第一端安装于安装孔22a内。
本实施例中，安装孔22a的槽底上可开设上述的过线孔20a，以方便走线布线。
进一步地，在一实施例中，参考图2和图4，摩擦块32套设于拉杆本体21插入于第一拉杆10内的一端上，摩擦块32设有供弹性件31的第二端抵接的固定槽。如此，可进一步地提升拉伸杆的拉伸顺畅度和稳定性，进一步地提升拉伸杆的使用寿命。
参考图2和图4，本实施例中，固定槽的槽底开设有走线孔32a。
需要说明，在第二拉杆20不包括支撑座22的情形中，如图2所示，摩擦块32的中部凸设有定位柱321，拉杆本体21上对应定位柱321的位置设有插孔，定位柱321插设于插孔中。如此，可方便组装，也可对摩擦块32进行限位定位，避免其偏位而影响拉伸杆的拉伸运动。
在第二拉杆20包括支撑座22的情形中，如图4所示，摩擦块32的中部凸设有限位柱322，支撑座22上对应限位柱322的位置设有通孔，限位柱322插设于通孔中。如此，提升了组装的便利性，也可限制摩擦块32沿第二拉杆20的长度方向移动，避免其偏位而影响拉伸杆的拉伸运动。
请参考图2和图4，在一实施例中，摩擦块32可包括第一摩擦块321和第二摩擦块322，第一摩擦块321与第二摩擦块322围合形成套管结构并套设于拉杆本体21上，第一摩擦块321和/或第二摩擦块322与拉杆本体21之间设有两组弹性件31。
在拉伸杆的伸缩过程中，弹性件31可通过第一摩擦块321/第二摩擦块322向第一拉杆10的内周壁提供正面稳定且均匀的挤压力，可极大提供拉伸杆的稳定性，并延长使用寿命。
在一些实施例中，弹性组件30还可包括摩擦片(图未示出)，摩擦片贴设于第一摩擦块321/第二摩擦块322上，或者摩擦片与第一摩擦块321/第二摩擦块322一体成型制造。如此，可保护第一摩擦块321和第二摩擦块322，避免其在长期使用后磨损而影响拉伸杆整体的稳定性，并进一步地提升了拉 伸杆的使用寿命。
需要说明，如图6所示，当拉杆本体21的插入端只有一侧设有沉槽时，第一摩擦块321与第二摩擦块322可为形状和大小不同的结构，第二摩擦块322的数量可为一个或多个，此处不限。如图5所示，当拉杆本体21的插入端两侧设有沉槽时，第一摩擦块321与第二摩擦块322可为相同的结构。
摩擦片的材质可为具有耐磨特性的金属或塑胶等，此处不限。
请参考图2和图4，在一些实施例中，第一拉杆10靠近第二拉杆20的一端可设有杆套11，以限制第二拉杆20从第一拉杆10中脱出。
本实施例中，杆套11还具有引导第一拉杆10活动的导向作用，可避免第一拉杆10偏离运动轨迹而损坏其与第二拉杆20之间的弹性组件30，提升了该拉伸杆的稳定性，并进一步地地延长了使用寿命。
本申请还提出一种支架，该支架包括拉伸杆，该拉伸杆的具体结构参照上述实施例，由于本申请提出的支架包括上述拉伸杆的所有实施例的所有方案，因此，至少具有与所述拉伸杆相同的技术效果，此处不一一阐述。
以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请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申请的专利保护范围内。
