Liftable isolating device for film watching room

Abstract

The invention relates to a liftable isolating device for a film watching room. The liftable isolating device for the film watching room comprises door columns, a cross beam is fixedly arranged at the upper ends of the door columns, and a bar-shaped through hole is formed in the middle of the cross beam. A shielding wall is arranged in the bar-shaped through hole in a through mode, a left hydraulic cylinder is fixedly arranged at the left upper end of the cross beam, and a right hydraulic cylinder is fixedly arranged at the right upper end of the cross beam. A left chain wheel is arranged at the upper end of the left hydraulic cylinder, and a right chain wheel is arranged at the upper end of the right hydraulic cylinder. The left chain wheel is matched to be provided with a left drive chain, and the right chain wheel is matched to be provided with a right drive chain. The inner side end of the left drive chain and the inner side end of the right drive chain are correspondingly fixed on the upper side of the left end face of the shielding wall and the upper side of the right end face of the shielding wall respectively. The outer side end of the left drive chain and the outer side end of the right drive chain are both fixed on the cross beam. According to the liftable isolating device for the film watching room, the lifting speed of the shielding wall is twice the extending speed of shafts of the hydraulic cylinders, and the lifting speed is high. A front down-pressing wheel and a rear down-pressing wheel are pressed on the shielding wall through a front down-pressing rack and a rear down-pressing rack with springs, the shielding wall is prevented from being shaken, and meanwhile hard pressing loss to the shielding wall is avoided.

Description

technical field [0001] The invention relates to the technical field of viewing room equipment, in particular to a liftable isolation device for a viewing room.
