The invention discloses an oil injection structure of an elevator threshold groove. The oil injection structure comprises a threshold, and the threshold is provided with a door plate capable of being opened and closed along the threshold in a sliding mode. The door plate comprises a door frame, one side of the door frame is open, a longitudinal oil injection pipe is arranged in the door frame and corresponds to the threshold groove of the threshold, a horizontal connecting pipe is arranged on the side wall of the door frame, and the connecting pipe communicates with the oil injection pipe. A supporting block is arranged on the inner side wall of the door frame, an arc part is formed on one side of the supporting block, and the arc part makes contact with the oil injection pipe. According to the oil injection structure of the elevator threshold groove, one side of the door frame of the door plate is open, the oil injection pipe is fixed through the supporting block and a pressing plate, the connecting pipe is connected with the oil injection pipe in a rotating mode, the oil injection pipe can be prevented from falling into the threshold groove due to the fact that the pipe diameter of the oil injection pipe is larger than that of the threshold groove, and oil injection operation of the threshold groove can be conveniently achieved.

    本发明公开了一种电梯门槛槽的注油结构,包括门槛,所述门槛上设置有沿其滑动开合的门板,所述门板包括门框,所述门框一侧敞开,门框中设置有纵向的注油管,所述注油管与门槛的门槛槽相对应,所述门框的侧壁处设置有水平的连接管,所述连接管、注油管连通。所述门框的内侧壁处设置有支撑块,所述支撑块一侧形成圆弧部,所述圆弧部与注油管相接触。本发明将门板的门框制成一侧开口状,通过支撑块和压板将注油管进行固定,通过连接管实现与注油管的转接,通过注油管的管径大于门槛槽能够避免注油管落入到门槛槽中,本发明能够方便的实现门槛槽的注油作业。
