The invention relates to an improved slide rail mechanism, an upper rail and a lower rail of a monorail assembly of the improved slide rail mechanism are mutually jointed to relatively longitudinally slide, a screw rod is arranged on the lower rail through a bracket assembly between the upper rail and the lower rail, a gear box assembly is arranged on the upper rail through a saddle-shaped bracket, the lead screw matches the gear box assembly to achieve longitudinal sliding of the upper rail and the lower rail, the upper rail is provided with an opening area, the saddle-shaped bracket is installed in the opening area, the gear box assembly is installed in the saddle-shaped bracket, the saddle-shaped bracket is provided with two bracket plates which are spaced in parallel, the two sides of each bracket plate are provided with protruding shoulders respectively, the upper rail is provided with a containing part, and the protruding shoulders cooperate with the containing part to improve the strength of the monorail assembly. According to the improved slide rail mechanism, the protruding shoulders of the bracket plates of the saddle-shaped bracket used for installing the gear box assembly match the containing part of the upper rail, the effective contact area on a stress path can be increased, and the strength of the monorail assembly and the strength of the whole slide rail mechanism are improved.

    本发明涉及一种改进型滑轨机构,其单轨总成的上轨和下轨彼此接合为相对可纵向滑动,丝杆在上轨和下轨之间通过支架组件被安装在下轨上,齿轮箱总成通过马鞍形支架安装在上轨上,丝杆与齿轮箱总成配合以实现上轨和下轨的纵向滑动,上轨具有开口区域,马鞍形支架安装在开口区域中,齿轮箱总成安装在马鞍形支架中,马鞍形支架具有彼此平行间隔开的两支架板,各支架板的两侧分别具有凸肩,上轨具有容纳部,凸肩与容纳部配合以提升单轨总成的强度。根据本发明的改进型滑轨机构,用于安装齿轮箱总成的马鞍形支架的支架板的凸肩与上轨的容纳部配合,可以增大受力路径上的有效接触面积,提升单轨总成和整体滑轨机构的强度。
