Abstract

The invention provides a lock device for panic door of a safety fence of a platform of a station capable of being installed in a thin door frame, securing a large stroke of a lock rod, and unreleasable by mischief and the wrong operation. A link mechanism is formed of a camshaft rotatably supported by a main body case, a rocking link having a guide projection inserted into a vertical long slot of the main body case at an intermediate part thereof, a slide link having a guide pivotal shaft inserted into the vertical long slot at a base end thereof, and a relay link for connecting the rocking link and the slide link to each other. This link mechanism is driven for extension and shrinkage by the vertical movement of a slider formed with a lateral long slot, in which an eccentric projection of the camshaft is fitted, so as to move the lock rod forward and backward to the lock position.

Description

technical field [0001] The invention relates to a lock device suitable for an emergency door. The emergency door is arranged at a proper position of a safety barrier installed at the end of a station platform, and can be opened and rotated in case of an emergency when the tram does not stop at a designated position, so that passengers can escape Use channel. Background technique [0002] In order to prevent passengers from falling from the platform or unexpected accidents caused to passengers due to the wind pressure of high-speed vehicles, a safety barrier is installed at the end of the platform on the line side. [0003] Such a safety barrier is provided with an opening at a position corresponding to the upper and lower openings of the vehicle, and the opening is always locked by a sliding door moving along the length direction of the safety barrier. When the electric car stops at the specified position, the electric or hydraulic drive mechanism drives the sliding door in...
