Abstract

The guide rail locking device for the railway vehicle door system comprises a vertical block and a guide rail, the interior of the vertical block is rotationally connected with a lead screw, the middle of the lead screw is fixedly connected with a round block, the outer wall of the right side of the lead screw is meshed with a connecting frame, and the bottom end of the connecting frame is fixedly connected with a sliding block; a locking device is arranged in the sliding block, and a limiting device is arranged on the left side of the connecting frame. According to the guide rail locking device for the railway vehicle door system, through cooperation of a sliding block, an inserting rod, a circular ring, a first spring, a ball and a conical barrel, when the sliding block moves to the position where the inserting rod is inserted, a needle tip of the inserting rod pushes the circular ring and the first spring leftwards till the ball rolls into a groove of the inserting rod, and the first spring presses the ball and the circular ring rightwards; and the conical barrel is trumpet-shaped, so that the problem that the vehicle door swings transversely due to the influence of external force such as road bumping when the vehicle door is closed is solved.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a guide rail locking device for a rail vehicle door system. Background technique [0002] The screw drive mechanism is widely used in rail vehicles, such as various vehicle doors, screen doors, civil doors, etc., and is equipped with locking and unlocking devices. At present, the commonly used passive locking devices for door systems include full passive locking, Screw passive locking, nut passive locking device. [0003] The rail locking device of the existing vehicle door system is affected by external forces such as road bumps when the vehicle door is closed, which causes the vehicle door to sway laterally, and the position of the vehicle door is easily unstable when the vehicle door is opened. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a guide rail locking device for a rail vehicle door system, so as to solve the proble...
