A protective double door

Abstract

The invention relates to the technical field of protective doors and discloses a protective double-leaf door. The protective double-leaf door comprises a first door leaf, a second door leaf and a drive device. The peripheral side faces of the first door leaf and the peripheral side faces of the second door leaf are all provided with covering edges covering and sealing the peripheral side faces of the door leaves. The covering edges of the inner side faces, located at the joint of the first door leaf and the second door leaf, of the door leaves are each provided with a boss portion, and the boss portions are matched with each other. The width of each boss portion is smaller than a half of the width of the inner side face of each door leaf. The drive device comprises a guide rail, rail wheel assemblies, an installation plate, a motor, a belt, belt pulleys and a controller, wherein the motor, the belt, the belt pulleys and the controller are arranged on the installation plate. The distance between the belt pulleys located at the two ends of the belt is larger than the width of the protective double-leaf door. The rail wheel assemblies connected with the first door leaf and the rail wheel assemblies connected with the second door leaf are connected to two segments, located in different movement directions, of the belt correspondingly. The two door leaves are synchronously driven to conduct the opening action or the closing action through the motor and the belt device, and therefore the movement speeds of the door leaves are equal. The drive device is simple in structure and reliable in strength.

Description

technical field [0001] The invention relates to the technical field of protective doors, in particular to a protective double-leaf door. Background technique [0002] The protective door is a key component of equipment rooms such as PET-MR and CT. For example, PET-MR is a large-scale functional metabolism and molecular imaging diagnostic equipment combined by the combination of PET and magnetic resonance imaging (MR) of positron emission tomography. complementary advantages. [0003] Due to the internal structure and material composition of the existing protective door, the radiation protection cannot meet the requirements, especially in the door gap and other places, the protective effect is not good, so that it cannot adapt to the environmental requirements of special equipment work. Furthermore, existing devices for realizing synchronous opening or closing of doors have complex structures and poor synchronous effects. Contents of the invention [0004] The technical ...
