Abstract: As an escape tool that can be configured at home, the escape retarder has become the important auxiliary equipment for residents to escape and rescue themselves in the event of fire in high-rise buildings because of its small size, simple operation and reciprocating use. In this paper, the industrial design software such as Creo and Adams are used to structural design, theoretical calculation and simulation analysis; then a new structure scheme is obtained, which provides a reference for the development and design of the compound escape retarder. It plays a certain role in promoting the diversified development of the mitigation structure.
