一、问题的由来在机箱和机柜中,有多种附件,如各种铰链、限动器、定位装置、锁紧装置、通风装置、导轨、把手、支脚等等,这些附件的好坏直接影响到机箱和机柜的使用性能,值得重视。目前在附件设计中参照前人经验,模仿某些机构是相当普遍的。应该说,对前人的设计经过“消化”,加以模仿,是正常的、必要的。但是,不能单纯照抄,只有真正“消化”,“吸收其营养”,进而改进前人设计,才能做到优化和发展。本文试图从机械原理上说明如何进行“消化”。 First, the origin of the problem In the chassis and cabinets, there are a variety of accessories, such as various hinges, stoppers, locating devices, locking devices, ventilation devices, rails, handles, feet and so on, the quality of these accessories directly affect To the chassis and cabinet performance, it is worth attention. It is quite common to imitate certain institutions by referring to the experience of predecessors in the annex design. It should be said that it is normal and necessary for the design of our predecessors to be “digested” and imitated. However, we can not simply copy, and only optimize and develop if we truly “digest” and “absorb their nutrition” to improve our predecessors’ designs. This article attempts to explain how to “digest” mechanistically.
