Horizontal-pushing-type manual unlocking handle device for platform safety door

Abstract

The invention relates to a horizontal-pushing-type manual unlocking handle device for a platform safety door. The horizontal-pushing-type manual unlocking handle device comprises a track side unlocking handle, a platform side unlocking tapered end, a handle reset spring and a rotating block. The platform side unlocking tapered end is installed on a frame pipe of the safety door. The track side unlocking handle is inserted into the frame pipe in a slideable mode in the door opening direction of the safety door via a guide structure arranged inside the frame pipe of the safety door. The track side unlocking handle can reset through the handle reset spring. The rotating block is in driving connection with the track side unlocking handle and the platform side unlocking tapered end. The track side unlocking handle moving in the door opening direction of the safety door can drive the rotating block to rotate through the slippage fit of a drive sliding groove and a drive pin, and the rotating block drives an unlocking assembly to unlock the safety door through a bracing wire in the rotating process. The horizontal-pushing-type manual unlocking handle device has the beneficial effects that in order to achieve an unlocking function, only certain unlocking force needs to be applied to the track side unlocking handle in the door opening slide direction, and there is no need to change the force application direction.

Description

technical field [0001] The invention relates to a horizontal push type manual unlocking handle device for a platform safety door. Background technique [0002] The rapid development of high-speed rail technology plays an increasingly important role in people's daily life. More and more high-speed rail and subway platforms are equipped with safety door systems. The configuration of safety doors can effectively isolate the track from the platform. Safety doors are equipped with manual unlocking Device to ensure that passengers or maintenance personnel can quickly and safely pass through the safety door. A comprehensive analysis of current existing products and a large number of patent documents shows that the manual unlocking device of the subway half-height security door sliding door basically adopts a rotary wrench structure, and the unlocking rotation direction is basically consistent with the sliding direction of the door. The rotary wrench must be rotated at a certain an...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: the existing manual unlocking device basically adopts a rotary wrench structure. During the process of unlocking and rotating, the direction of applying force to the rotating wrench is constantly changing at first, and the direction of applying force after the rotation is terminated is relatively It is the "effective direction", which will affect the unlocking speed and reliability, and is not conducive to passengers or maintenance personnel passing through the safety door quickly and safely.
