新型脚轮上部连接的结构设计及优化
|
摘要
传统办公室的转椅底部的转轮连接主要依靠圆柱上的螺纹,使用久了容易磨损而使螺纹不能起到固定作用从而转轮容易脱离连接,而另一种卡口式则在损坏更换的拆卸中需要更换者使用很强的外力来进行拆卸,容易对更换的人员造成伤害,稳定性一般,局限性较大,因此有必要对现有技术进行改进,本次设计在分析了传统脚轮连接存在的缺点和不足后,提出一种新的连接方式,阐述了新型脚轮连接设计的基本结构并对设计加以改善。
The runner connection at the bottom of the traditional office swivel chair mainly relies on the thread on the cylinder.After longtime usage, the thread will not be fixed and the runner can be easily disconnected. Meanwhile, for the other bayonet type,during the replacement disassembly after the damage, a strong external force is needed, which is easy to hurt the replacement personnel. This type also has the disadvantage of poor stability and limitations. Therefore, it is necessary to improve the existing technology; after the analysis of the traditional caster connection shortcomings, a new connection method is proposed, and the basic structure of the new caster connection design is expounded and optimized.
