Flashboard type airtight door based on electromagnetic repulsion principle

Abstract

The invention relates to the technical field of air-tight doors, and discloses a flashboard type air-tight door based on the electromagnetic repulsion principle. The door comprises a device main body,a fixed base is arranged at the bottom of the device main body, a driving device is arranged in the device main body, and a driving screw rod is fixedly connected to the inner side of the driving device. A through connection shaft center is arranged in the driving screw rod, a bearing shaft center is movably installed on the inner side of the driving screw rod, one end of a connecting rod is fixedly connected to the outer side of the through connection shaft center, a connecting plate is movably connected to the other end of the connecting rod, and a bearing screw rod is movably connected tothe upper portion of the bearing shaft center. According to the flashboard type airtight door based on the electromagnetic repulsion principle, by rotating the rotating hand wheel arranged on the flashboard type airtight door, the rotating hand wheel immediately and synchronously drives the hand wheel support to start rotating, the electromagnetic block connected to the outer side of the flashboard type airtight door immediately and synchronously rotates, an internal switch assembly and device are triggered to be started through the electromagnetic effect, and the purpose of controlling a switch to be closed is achieved.

Description

technical field [0001] The invention relates to the technical field of airtight doors, in particular to a gate-type airtight door based on the principle of electromagnetic repulsion. Background technique [0002] In workplaces that require strict isolation between internal and external passages, such as radioactive places and various special laboratories, etc., where passage sealing doors must be provided, if strict sealing cannot be achieved, cross-contamination may occur, which in turn leads to a series of environmental and health problems. question. There are two main types of airtight doors: [0003] 1. Inflatable airtight door, that is, after the door is closed, the air is added to the sealing strip to expand the sealing strip to achieve sealing. Its disadvantage is that the equipment and structure are complicated, a supporting air source is required, and the service life of the sealing strip is short. 2. The mechanical swing-type airtight door, that is, the general ...

AI Technical Summary

Problems solved by technology

Its disadvantages are that there are relatively large requirements for the installation position, the mechanical structure is complicated, and the overall volume of the door is relatively large.
