阅读说明：本技术 轨道组件 (Track assembly ) 是由 马建良 张辉 王超 刘骋远 肖发辉 于 2020-05-14 设计创作，主要内容包括：本申请涉及一种轨道组件。轨道组件包括轨道和支撑构件,支撑构件连接到轨道并构造成沿着轨道移动。支撑构件可以包括接合部分。接合部分可被配置为在轨道组件的加载状态下接合轨道,以限制轨道和支撑构件之间的相对移动。接合部分可被配置为在轨道组件的非加载状态下不操作地接合轨道,也不限制轨道和支撑构件之间的移动。(The present application relates to a track assembly. The track assembly includes a track and a support member connected to the track and configured to move along the track. The support member may include an engagement portion. The engagement portion may be configured to engage the rail in a loaded state of the rail assembly to limit relative movement between the rail and the support member. The engagement portion may be configured to not operatively engage the rail in the unloaded state of the rail assembly, nor to restrict movement between the rail and the support member.)
