The invention discloses a seat sliding rail, and the sliding rail comprises upper rails, lower rails, a connecting rod and steel balls, wherein the two ends of the connecting rod are each connected with one upper rail, the two upper rails are each connected with one lower rail in a sliding mode, a steel ball supporting frame is arranged on the lower surfaces of the upper rails, a plurality of steel balls are arranged in the steel ball supporting frame, and the lower ends of the steel balls are located outside the steel ball supporting frame; the upper end of the connecting rod is provided witha groove, a shaft rod is disposed in the groove in the upper end of the connecting rod, and two ends of the shaft rod are respectively disposed in the upper rails. The sliding rail is reasonable in structure, a steel ball supporting frame is arranged in the upper rails, and the plurality of steel balls are arranged in the steel ball supporting frame, so the abrasion is reduced, a friction surfaceis reduced, and the noise and discomfort caused by vibration are reduced; the steel ball supporting frame is adopted for limiting the steel balls, and the steel ball supporting frame is of a detachable structure, so the replacement and maintenance of the steel ball are facilitated.

    本发明公开了一种座椅滑轨,包括上轨道、下轨道、连杆及钢珠,连杆两端各与一个上轨道相连,两个上轨道各与一个下轨道滑动连接,上轨道的下表面设置有钢珠支撑架,钢珠支撑架内部设置有若干个钢珠,钢珠的下端位于钢珠支撑架的外部,连杆上端开设有凹槽,连杆上端的凹槽内设置有轴杆,轴杆的两端分别设置于上轨道内部,该发明结构合理,上轨道内部设置有钢珠支撑架,钢珠支撑架内部设置有若干个钢珠,减少了磨损,减小了摩擦面,也就减少了振动带来的噪音和不适,采用钢珠支撑架对钢珠进行限位,且钢珠支撑架为可拆卸结构,便于钢珠的更换及保养。
