摘　　要：国内市场上电动牙科病人椅背靠前后倾大多采用平面连杆机构实现背靠单倾和背靠-座板联动。在实践中通过对连杆机构类型和尺度的调整,逐步改进设计,丰富了机型,并达到了单倾机构尺度优化和联动机构水平大补偿的目的,更好地满足客户要求。Planar linkage mechanisms are mostly used in domestic market to achieve the unilateral or compensated movement of the backrest.In the practice of adjusting the types and dimension of the mechanisms,we improve the design and enrich the models,and succeed in optimizing the dimension of the unilateral movement mechanism and the long-distance compensated movement mechanisms.The requirement of customers are satisfied better.
