Cover plate door closing damping force value adjustable device
The invention provides a cover plate door closing damping force value adjustable device which structurally comprises a main body, a large folding arm, a damping impeller, a cover plate, a small folding arm and a needle roller bearing. The main body is cylindrical and hollow, the large folding arm is fixed on the upper surface of the main body, and the top end of the large folding arm is provided with the small folding arm; the needle roller bearing penetrates through a hole in the center of the damping impeller and is installed in a central convex cylindrical groove of a cavity in the main body, the cover plate is installed on the circular side surface of the main body, and holes are formed in the centers of the main body and the cover plate and are located on the same axis as the axes ofthe damping impeller and the needle roller bearing; the device further comprises a fixing support, a fixing shaft is arranged in the center of the fixing support, and the fixing shaft penetrates through the hole in the center of the main body or the cover plate and is fixed. The cover plate door closing damping force value adjustable device can adapt to cover plate structures of different materials, sizes and weights, does not need to distinguish mounting positions, is simple in structure, convenient to assemble and replace, and easy to implement and popularize.
本发明提出的是一种盖板门关闭阻尼力值可调装置，其结构包括主体、大折臂、阻尼叶轮、盖板、小折臂、滚针轴承；其中主体呈圆柱形，内部中空，大折臂固定于主体上表面，大折臂的顶端设有小折臂；滚针轴承穿过阻尼叶轮中心的孔洞安装于主体内部空腔的中心凸起圆柱槽内，盖板安装于主体的圆形侧面，主体和盖板的中心设有孔洞，与阻尼叶轮和滚针轴承的轴心位于同一轴线上；该装置还包括固定支架，固定支架的中心设有固定轴，固定轴穿过主体或盖板中心的孔洞并固定。本发明可适应多种不同材质、尺寸和重量的盖板结构，无需区分安装位置，结构简单，装配和更换方便，易于实施和推广。
