如图14、15、16所示：所述的任意停阻力伸缩杆，用摩擦轮17替代拨爪2，摩擦轮17的外缘和接近外缘的区间采用弹力柔性材料，受到齿形滑道5的压力，会发生弹性变形，摩擦轮17的外缘未受到外力作用时到轴1中心线的距离大于齿形滑道外缘距轴1中心线的距离，且两轴1中心线距离不大于摩擦轮17的外缘未受到外力作用时的两轮半径之和，为增加伸缩杆的伸缩移动阻力，可采用多轮组合，伸缩杆的伸缩移动阻力与摩擦轮17的受压形变量和参与形变量的摩擦轮17的数量成正比，齿形滑道5的h≥0，L≥0。改变齿形滑道5的齿形角度A和/或B可调整拉杆7正反移动的阻力大小。例如台式电脑显示器、阅读架、灯架等设备装置调整高度时，总是希望落下时阻力大些，以避免容易向下滑落，而民用箱包的拉杆则希望将拉杆拉出伸长的阻力设计为大于回抽复原的阻力。As shown in Figures 14, 15, and 16: For the said arbitrary stop resistance telescopic rod, the friction wheel 17 is used to replace the claw 2. The outer edge of the friction wheel 17 and the area close to the outer edge are made of elastic flexible materials, which are subjected to the toothed slideway. 5 pressure, elastic deformation will occur. When the outer edge of the friction wheel 17 is not subjected to external force, the distance from the center line of the shaft 1 is greater than the distance between the outer edge of the toothed slide and the center line of the shaft 1, and the distance between the center lines of the two shafts 1 is not greater than The sum of the radii of the two wheels when the outer edge of the friction wheel 17 is not affected by external force, in order to increase the telescopic movement resistance of the telescopic rod, a combination of multiple wheels can be used. The telescopic movement resistance of the telescopic rod and the pressure deformation of the friction wheel 17 The number of friction wheels 17 of the deformation amount is proportional to h≧0 and L≧0 of the toothed slideway 5 . Changing the tooth angle A and/or B of the toothed slideway 5 can adjust the resistance of the pull rod 7 to move forward and backward. For example, when adjusting the height of equipment such as desktop computer monitors, reading racks, light stands, etc., it is always hoped that the resistance will be larger when falling, so as to avoid falling down easily, while the pull rod of the civilian luggage is expected to be pulled out. The extension resistance is designed to be Greater than the resistance of the retraction recovery.
所述阅读架的配重18与底板12相连接，配重18采用物体或者采用文具盒亦或是采用磁力连接以及吸盘，当采用吸盘时，该吸盘用于吸附于阅读架所放置的平面。The counterweight 18 of the reading frame is connected with the bottom plate 12, and the counterweight 18 is an object or a stationery box or a magnetic connection and a suction cup. When a suction cup is used, the suction cup is used to adsorb on the plane on which the reading frame is placed.
所述阅读架的使用方法是：将所阅书籍或板状阅读物用夹子15夹住，底板12与所放置的平面重合或者与所放置的平面形成角度。The use method of the reading rack is as follows: the book or plate-shaped reading object to be read is clamped with the clips 15, and the bottom plate 12 coincides with the placed plane or forms an angle with the placed plane.
如图12所示：是一种灯架，包括灯11连接杆14、转动轴13、底座16，其中连接杆14采用本发明技术方案一至四所述的一种任意停阻力伸缩杆；如图17所示：是一种台式电脑支架显示器18通过轴13与支架14链接，支架14与底座16相连，支架14采用本发明技术方案一至四所述的任一种任意停阻力伸缩杆。调整显示器高度，其支架14设计为下降的阻力大于提升的阻力。As shown in Figure 12: it is a lamp stand, including a connecting rod 14 of the lamp 11, a rotating shaft 13, and a base 16, wherein the connecting rod 14 adopts an arbitrary stop resistance telescopic rod described in the technical solutions 1 to 4 of the present invention; as shown in the figure Shown in 17: a desktop computer stand display 18 is linked with the stand 14 through the shaft 13, the stand 14 is connected with the base 16, and the stand 14 adopts any one of the arbitrary stop resistance telescopic rods described in the technical solutions 1 to 4 of the present invention. To adjust the height of the monitor, its stand 14 is designed so that the resistance to lowering is greater than the resistance to lifting.
