Automatic lifting door for vacuum chamber sealing
The invention belongs to the technical field of vacuum chamber sealing, and particularly relates to an automatic lifting door for vacuum chamber sealing. The automatic lifting door comprises a door plate, a lifting driving mechanism, a four-bar linkage mechanism and a limiting structure, wherein the four-bar linkage mechanism is connected to one side of the door plate; the lower end of the four-bar linkage mechanism is connected with the lifting driving mechanism; the limiting structure is arranged above the four-bar linkage mechanism and used for limiting the ascending stroke of the four-barlinkage mechanism; the lifting driving mechanism drives the four-bar linkage mechanism and the door plate to ascend to be in contact with the limiting structure; and the four-bar linkage mechanism isunfolded in the horizontal direction through limiting of the limiting structure, so that the door plate is attached to a vacuum chamber, and sealing of the vacuum chamber is achieved. According to theautomatic lifting door, lifting and door opening and closing actions are completed by utilizing a spring and the four-bar linkage mechanism, the structure is simple, the operation is convenient, thecost is reduced, and the sealing effect is good.
本发明属于真空腔室密闭技术领域，特别涉及一种真空腔室密闭用自动升降门。包括门板、升降驱动机构、四连杆机构及限位结构，其中四连杆机构连接在门板的一侧，四连杆机构的下端与升降驱动机构连接，限位结构设置于四连杆机构的上方，用于限制四连杆机构的上升行程，升降驱动机构驱动四连杆机构和门板上升至与限位结构接触后，四连杆机构通过限位结构的限位沿水平方向展开，从而使门板与真空腔室贴合，实现真空腔室的密封。发明利用弹簧和四连杆机构完成升降及开关门动作，结构简单，操作方便，降低成本，且密闭效果比较好。
