Abstract

The invention discloses a single-opening sliding plug door system, which comprises a motor, wherein the motor is fixed on a cross beam, and is connected with a controller; a shaft of the motor is connected with a lead screw; a screw nut assembly is arranged on the lead screw, and comprises a screw nut and a following component; the following component is in rigid connection with the screw nut; the screw nut and the leads screw form a spiral movement pair; a transmission frame is arranged at the outer side of the screw nut; a torsional spring is arranged between the transmission frame and the screw nut, and exerts the pressure onto the following component by using the transmission frame as the support; the transmission frame is connected with a controlled object; a slide rail is arranged on the cross beam; and the following component is in contact with a position limiting mechanism when moving to a position that the slide rail approaches to the end part of the position limiting mechanism. The single-opening sliding plug door system has the advantages that the following component always receives the pressure of the torsional spring in the whole motion stroke; the pressure is adjustable; the operation is stable; the single-opening sliding plug door system can easily enter the locking position; after the impact vibration is received, rolling wheels cannot be easily disengaged from the locking position; the locking position of the following component is visible; the locking state can be seen; and the safety is high.

Description

technical field [0001] The invention relates to the field of doors, in particular to a single-open plug-and-pull door system. Background technique [0002] The screw drive used in the existing single-opening sliding door system is generally a motor-driven screw rod, which drives the nut assembly arranged on the screw rod to reciprocate, and then drives the controlled object connected to the nut assembly. Generally speaking, the single-opening sliding door system is mostly used in the field of rail transit, bus and other public transportation vehicle doors, and it also has locking and unlocking functions. Generally used in the single-opening plug-and-pull door system in the above-mentioned fields, the nut assembly is locked by an electromagnetic lock, thereby realizing the function of locking the door. In this form of single-opening plug-and-pull door system, the electromagnetic lock must be powered on at any time to ensure the stability of the door lock. If the electromagne...
