Description

technical field [0001] The invention relates to a jack safety device, in particular to a jack safety device for a subway door leaf. Background technique [0002] The subway civil air defense partition door is used in the subway tunnel and is normally open. After the door leaf is opened in place, it must be fixed in place with a jack safety device. It is strictly forbidden for the door leaf to rotate freely, otherwise it will bring extremely serious adverse consequences to the normal operation of the subway vehicles. . The original jack safety device for the civil air defense partition door of the subway is relatively bulky as a whole, and it is inconvenient to open and close. The outer shell only uses a 2mm thin plate, which has poor safety performance. After the subway door is closed, personnel can open the jack safety device at will, which is greatly affected by human factors. The normal operation of subway vehicles brings great potential safety hazards. Contents of the...
