Intelligent security door opening and closing device based on electrorheological fluid

Abstract

The invention relates to the technical field of intelligent security technologies, and discloses an intelligent security door opening and closing device based on an electrorheological fluid. The device comprises a door frame and a shell, wherein a door plate is movably connected to the outside of the door frame, a nitrogen spring is movably connected to the outside of the door plate, a sliding rodis movably connected to the outside of the door plate, and a rotating wheel is fixedly connected to the outside of the door plate; under the interaction of the door frame, the door plate, the nitrogen spring, the sliding rod, the rotating wheel, a fixed shaft, the electrorheological fluid, a spring and a clamping rod, the door plate can be automatically closed under the automatic reset effect ofthe nitrogen spring after being opened, and therefore the door plate is more suitable for the use habit of daily personnel; and when the door plate needs to be thoroughly opened so that large objectscan enter and exit, the door plate can be temporarily fixed through the characteristic of the electrorheological fluid, closing of the door plate is avoided, opening and closing of the door plate areadjustable, and the device is more suitable for being used under actual conditions.

Description

technical field [0001] The invention relates to the technical field of intelligent security technology, in particular to an intelligent switch device for security doors based on current variants. Background technique [0002] Security can be understood as an acronym for "safety protection". It is used to deal with attacks or avoid victims, so that the protected object is in a safe state where there is no danger, no infringement, and no accidents.

Problems solved by technology

[0006] Aiming at the deficiencies of the existing technology, the present invention provides an intelligent switch device for security doors based on current variants, which has the advantages of timely closing and adjustable door switch, and solves the problem that some companies still use traditional glass doors. Due to the lack of timely closing and daily protection functions of the glass door, there is no way to effectively block the entry of outsiders, so that the company's property cannot be effectively protected, and some companies will install electric suction doors for daily security. Protection, but such an electric suction door cannot be closed when it is fully opened, which will keep the door open for a long time, so that there is no way to fully guarantee the company's property and personnel safety, which is not conducive to the actual situation problems with the use of
