摘要
传统的急救担架车外观比较笨重,不宜在灾难急救中携带使用;另一方面它的结构比较复杂,不易安装,操作困难,只能推用而不能担用。针对这些缺点,本设计进行全面机构创新改革,应用连杆机构的传动原理,使新型的折叠式担架车既能推用又能担用,而且担架和担架车的转换简便快捷、体型轻巧、结构简单、便于携带、安装和操作。
As the traditional stretchers looks much heavier, they are not suitable for carrying and operating during first aid in a disaster on one hand, and on the other hand, their structures are much complicated, uneasy to assembly and difficult to operation, they can only be used by pushing not shouldering. For these disad- vantages, this design has innovatively reformed the overall structure by applying the transmission theory of link mechanism, causing the new foldable stretcher can be either pushed or shouldered. And the transformation between hand frames and stretcher becomes simpler and quicker, since it is compact in size, simple in structure, easy for carrying, assembling and manipulating.
