Pass box

Abstract

The invention relates to a pass box, in particular relates to an airtight pass box for a medical and biological clean room. The pass box consists of a box body of which two ends are communicated, two door leaves mounted at the parts where the two ends of the box body are communicated, and an interlocking device, wherein the two door leaves mounted at the parts where the two ends of the box body are communicated, an electromagnetic lock and an interlocking sensor constitute the interlocking device; the external part of the box body is square-shaped; each chamfer part in the channel of the box body is arc-shaped; the two door leaves are mounted on the box body in an embedded manner; when the two door leaves are closed, the two door leaves and the box body are located on the same plane; transparent double-layer windows are arranged in the middle of the two door leaves; the double-layer windows are fixedly and hermetically connected with the door leaves by sealant; and the width of the double-layer windows is the same as that of the door leaves, so that a level plane can be formed by the double-layer windows and the door leaves. For the pass box of the invention, the width of the double-layer windows is the same as that of the door leaves, and the double-layer windows and the door leaves are located on the same plane, so as to form a whole having the advantages of levelness and smoothness, high air tightness, dust retention prevention and easiness of clean.

Description

Technical field: [0001] The invention relates to a transfer window, in particular to an airtight transfer window of a medical biological clean room. Background technique: [0002] The transfer window of the medical and biological clean room is used for the transfer of materials and tools between clean rooms or between clean rooms and non-clean rooms. The requirements for the transfer window are no dust, no dust, easy to clean, and It should have good airtightness, and there are doors on both sides that cannot be opened at the same time. The door of the transfer window of the existing medical clean room and the box are not on the same plane, and there are more dust accumulation surfaces; the gap between the door of the transfer window and the box affects the airtight effect; the window on the door of the transfer window adopts a single A piece of glass and a frame frame of the window frame are connected and fixed to form more dust accumulation surfaces, which are easy to acc...
