Safety anti-overflow door of toxic gas sensing device

Abstract

The invention discloses a safety anti-overflow door of a toxic gas sensing device. The safety anti-overflow door comprises a safety door casing, wherein a working cavity is arranged in the safety doorcasing; a hollow cavity positioned at the right side of the working cavity is arranged in the safety door casing; a linkage cavity positioned at the upper side of the working cavity is arranged in the safety door casing; the linkage cavity is provided with a door opening and closing assembly; the door opening and closing assembly comprises sealing doors and fixing blocks; the sealing doors are glidingly connected to the inner wall of the lower side of the working cavity in a bilateral symmetry way; and each fixing block is fixedly arranged on the upper end of the corresponding sealing door. According to the safety anti-overflow door, when an experimenter enters a laboratory, the gap between the sealing doors at the left and right sides is automatically increased; the door opening operation is realized; during door opening, a rotating fan can generate a wind curtain, so that air with a lower temperature in the laboratory is isolated from external air with a higher temperature; a toothed block is used; when toxic gas leaks, the toothed block can be timely meshed and connected with a first gear, so that the sealing door is prevented from being opened again; and the effect of preventing the diffusion of the leaked toxic gas is achieved.

Description

technical field [0001] The invention relates to the technical field of induction doors, in particular to a safety anti-overflow door of a poisonous gas induction device. Background technique [0002] The cyanide standard solution in the water for cyanide testing needs to be refrigerated and stored, which is a dangerous and poisonous drug. In places like laboratories that need to be frequently entered and exited, electric doors are often used to facilitate the entry and exit of experimenters. However, the electric doors of most laboratories are not equipped with poisonous gas detection devices, and cyanide is a highly toxic chemical substance. Once a leak occurs, it will be very dangerous when there are unsuspecting experimenters who need to enter and the electric door opens automatically. Dangerous, a kind of device that the present invention illustrates can solve the above-mentioned problem. Contents of the invention [0003] The object of the present invention is to pro...
