Self-locking type ring lock scaffold capable of conveniently adjusting scaffold body height
The invention relates to a self-locking type ring lock scaffold capable of conveniently adjusting the scaffold body height. The scaffold comprises a vertical rod and a transverse rod. The vertical rodis sleeved with an annular connecting disc. A middle rod is wound by a spiral fin. An elevation angle a is formed between the horizontal plane and the spiral fin. The elevation angle a and the equivalent friction angle b of the spiral fin meets the equation: a<=b<=1.2a, the middle rod located above the connecting disc is sleeved with an annular disc in a spaced mode, a plurality of sliding railsare fixedly connected to the edge of the lower surface of the annular disc, a sliding block is in slidable connection with each sliding rail, an arc plate is fixedly connected to one end of each sliding block, teeth are arranged on the inner surface of the arc plate, the other end of each sliding block is connected with the edge of the connecting disc through a connecting rod, the sliding blocks,the connecting rods and the connecting disc are matched to form a slider-crank mechanism. The device achieves the effect of adjusting the height of the horizontal scaffold height, the scaffold can beself-locked more firmly, and the scaffold is applicable to industrial production and has the high practicability.
本发明涉及一种便于调节架体高度的自锁式盘扣脚手架。该装置包括有竖杆与横杆，竖杆上套接有环状的连接盘，中间杆上缠绕有螺旋肋片，螺旋肋片与水平面之间形成升角a，升角a与螺旋肋片的当量摩擦角b之间的关系为：a≤b≤1.2a，位于连接盘上方的中间杆上间隙套接有环形圆盘，环形圆盘下表面边檐固接有多根滑轨，各滑轨上均滑动连接有滑块，滑块一端固接有弧形板，弧形板内表面上设置有齿牙，滑块另一端经连杆与连接盘边檐连接，滑块、连杆以及连接盘之间配合形成曲柄滑块机构，该装置既达到了调节水平脚手架高度的作用，同时使得该脚手架自锁更加牢固，适用于工业生产中，具有很强的实用性。
