Abstract

The invention provides a sealing box door assembly which is used for opening or sealing a sealing box and comprises a first door used for being in sealing butt joint with a sealing box door and a second door arranged on the outer side of the first door; and when the sealing box door is closed and sealed, the first door is in sealing butt joint with the sealing box door, a first sealing cavity is formed between the second door and the outer wall of the sealing box and between the second door and the first door, the first sealing cavity and the sealing box have air pressure P2 and P1 respectively, P2 is larger than P1, the pressure P2 in the first sealing cavity exerts lateral pressure on the first door, and the first door is pushed to the sealing box, so that the sealing performance is effectively improved.

Description

technical field [0001] The invention relates to the technical fields that are applied to sealed operating environments such as sealed operation boxes, nitrogen and argon protection boxes, radioactive operation boxes, glove type operation boxes, etc., and particularly relates to a sealed box door assembly and a sealed box. Background technique [0002] The sealed box is a box made of metal, glass or plastic, which is used in technical fields that require a sealed operating environment, such as sealed operation boxes, nitrogen and argon protection boxes, radioactive operation boxes, and glove-type operation boxes. These sealed boxes are generally provided with a sealed box door for changing materials, repairing or assembling cables or interfaces. For example, the main box of the glove box has multiple openings for installing windows, transition chambers, glove interfaces, cables and other accessories. Operators operate the materials and equipment in the box through these wind...
