Shielding electric fan-shaped door
The invention discloses a shielding electric fan-shaped door. The shielding electric fan-shaped door comprises a door frame and a door body, wherein the right side of the door body is hinged to the door frame, the left side of the door body is rotationally connected with a rotating shaft, and the two ends of the rotating shaft extend out of the door body and are connected with an outer handle and an inner handle correspondingly. According to the shielding electric fan-shaped door, a spur gear and double spur racks are adopted for reciprocating linear conduction, a needle bearing and a linear bearing which are high in machining precision and stable in performance are matched for guiding, mechanical friction is reduced, hard contact is reduced, all the adopted mechanisms are externally installed, when power is suddenly cut or a motor breaks down, the shielding door can be directly opened through manual operation after an emergency stop button is pressed down, the safety of a user is guaranteed, the structure that a conical knife and a L-shaped knife are matched with a beryllium copper reed is adopted, the conical knife can solve the precision problem in the production and machining process, the L-shaped knife plays a re-shielding effect, errors generated in the production and machining process can be compensated through the conical knife inserting structure on the door, the production and machining errors are reduced, and therefore the shielding performance is stable and superior.
本发明公开一种屏蔽电动扇形门，包括门框和门体，所述门体右侧铰接安装在门框上，所述门体左侧转动连接有转动轴，所述转动轴的两端分别延伸至门体外部并分别连接有外把手和内把手；本发明采用直齿轮与双直齿条作往复直线传导，配合加工精度高且性能稳定的滚针轴承与直线轴承作导向，减少机械摩擦，降低硬接触，采用机构全部外置安装，在突然停电或电机出现故障时，按下急停按钮后即可直接手动操作开启屏蔽门，保障了用户的安全性，采用锥形刀及L型刀与铍铜簧片配合的结构，锥形刀可以解决生产加工中精度的问题，L型刀起到再次屏蔽效果，通过门上锥度插刀结构可以补偿生产加工中产生的误差，生产加工误差减小，从而使屏蔽性能稳定优越。
