Abstract

The invention discloses a double-sliding-plug-door system which comprises a sliding-plug rail, mechanism mounting frames arranged at the two ends, a bearing support, a driving mechanism fixed to the bearing support, bilaterally-symmetrical locking slide ways and a locking mechanism. The driving mechanism comprises a screw rod driven by a motor and transmission assemblies arranged in a bilateral symmetry mode, and the screw rod drives the transmission assemblies to reciprocate in the axial direction of the screw rod. Each transmission assembly comprises a transmission frame, a nut assembly arranged on the corresponding screw rod in a sleeving mode and a locking roller fixed to the nut assembly, wherein the nut assembly is mounted in the transmission frame which is connected with a controlled object. The locking mechanism comprises baffle assemblies and reset torsional springs, wherein the baffle assemblies are rotatably connected with the corresponding bearing support and arranged in abilateral symmetry mode, one ends of the reset torsional springs are fixed, the other ends of the reset torsional springs are fixedly connected with the baffle assemblies, the reset torsional springsare used for limiting rotation of the baffle assemblies, and locking spaces where the locking rollers can fall into are formed by the baffle assemblies and the side faces of the corresponding lockingslide ways. According to the double-sliding-plug-door system, the safety risk problem of existing door systems is solved.

Description

technical field [0001] The invention relates to the field of doors, in particular to a double-opening plug-and-pull door system. Background technique [0002] The double-opening sliding door system is generally a motor-driven screw, which drives the nut assembly set on the screw to reciprocate, and then drives the controlled object connected to the nut assembly. Generally speaking, the double-opening sliding door system is mostly used in the field of track doors and electric doors, and it also has locking and unlocking functions. Usually used in the double-opening plug-and-pull door system in the above fields, the nut assembly is locked by an electromagnetic lock, thereby realizing the function of locking the door. In this form of double-opening plug-and-pull door system, the electromagnetic lock must be energized at any time to ensure the stability of the locked door. If the electromagnetic lock is powered off, there will be a risk that the door will automatically open. Ho...
