Sliding-plug door

Abstract

The invention relates to a sliding-plug door. The sliding-plug door comprises a driving mechanism, block connecting rod mechanisms and locking and unlocking mechanisms; the driving mechanism is arranged at the middle position and can provide driving force for the block connecting rod mechanisms which are symmetrically arranged on the left side and the right side of the driving mechanism so as to complete sliding-plug action and drive the locking and unlocking mechanisms which are symmetrically arranged on the left side and the right side to complete unlocking and locking actions when the dooris opened or closed; and the action input ends of the block connecting rod mechanisms are connected with the driving mechanism, the action output ends of the block connecting rod mechanisms are connected with a left door leaf or a right door leaf, and the block connecting rod mechanisms are used for providing driving force with the same effect for the left door leaf or the right door leaf connected with the block connecting rod mechanisms to enable the left door leaf and the right door leaf to do opposite movement or contrary movement simultaneously. According to the sliding-plug door, the driving mechanism is arranged at the middle position, the block connecting rod mechanisms and the locking and unlocking mechanisms are symmetrically arranged on the two sides of the driving mechanism, and the defects that the actions are inharmonious, and the two door bodies are stressed unevenly can be overcome through the structure.

Description

technical field [0001] The invention relates to the technical field of sliding doors, in particular to a sliding door which is applicable to rail vehicles and public vehicles and uses the same power output for the plugging and unlocking actions. Background technique [0002] In the prior art, along with the continuous development of my country's railway passenger transport, the airtightness, convenience and flexibility of train doors have gradually become its very important indicators. Therefore, a large number of new technologies have been adopted in the speed-up bus, and the plug door is one of them: the plug door is a product integrating gas, electricity and machinery. The so-called plug door mainly means that the door has two actions of plugging and pulling That is, when the door is closed, it is stuffed into the door of the car from the inside or outside of the car to make it closed and sealed; At present, the electric sliding doors used in some cities in the market ar...
