A platform for research: civil engineering, architecture and urbanism
The invention discloses a telescopic protective door fence which is characterized in that one of a first support and a second support is provided with a supporting piece extending into a reel pipe, a damper is installed on the supporting piece, the damper is connected with a reel through a transmission structure, and when the reel rotates in the direction of rolling a roller shutter assembly, the damper is driven to rotate by the transmission structure. The damper can generate motion resistance to the reel and consume elastic potential energy of the first torsional spring so as to reduce the rotating speed of the reel, so that the situation that people or other objects are collided and injured in the roller shutter assembly recycling process is avoided, and meanwhile the roller shutter assembly and the reel can be prevented from being damaged.
本发明公开了一种伸缩防护门栏,其在第一支座和第二支座之一者设有伸入卷管的支承件,在支承件上安装有阻尼器,并通过传动结构将阻尼器与卷轴相连,当卷轴往收卷卷帘组件的方向转动时,所述阻尼器可对卷轴产生运动阻力并消耗第一扭簧的弹性势能,以降低卷轴的转动速度,从而避免卷帘组件回收过程中出现撞伤人或者其他物体的情况,同时也可避免损坏卷帘组件本身及卷轴。
