Electromagnetic shielding door with flexible shaft emergency opening device

Abstract

An electromagnetic shielding door with a flexible shaft emergency opening device comprises a door frame and a door body, and the door frame is provided with a double-shaft motor; a first bevel gear is arranged at the tail end of a motor connection shaft of the double-shaft motor in a sleeving mode and is connected to the flexible shaft emergency opening device, and the flexible shaft emergency opening device comprises matched bevel gears and a flexible shaft; a U-shaped supporting frame is arranged at the part, located on one side of the first bevel gear, of the door frame and comprises guide plates and a side plate connected to the guide plates, various rotation shafts penetrate through the U-shaped supporting frame, a rotation shaft support and a U-shaped connection frame below the rotation shaft support are arranged in an inner cavity of the door frame, and the lower end of the U-shaped connection frame is connected to a pull rope. When the electromagnetic shielding door is normally used, the door body can be automatically opened or closed by driving two locking slide blocks installed on the door frame in a sliding mode to move synchronously and vertically through the double-shaft motor. In addition, the electromagnetic shielding door can be opened or closed by manually operating the flexible shaft emergency opening device. The operation is simple, safe and reliable, and the shortcomings of the prior art are overcome.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic shielding doors, and mainly relates to an electromagnetic shielding door with a flexible shaft emergency opening device. Background technique [0002] At present, the screen door installed in the electromagnetic shielding room mainly adopts the swing door connected by hinges, and the opening and closing of the screen door has two kinds of locking mechanisms: electric control lock and manual lock. The electromagnetic shielded door that adopts electronic control to open and close only uses the biaxial motor installed above the door body to drive the locking slider installed on the door frame through the rack transmission mechanism, and utilizes the tilt angle on the locking slider to , so that when the lock pin installed on the door body is separated from the locking slider, the door body is separated from the door frame. However, due to the limitation of the inclination angle of the lockin...

AI Technical Summary

Problems solved by technology

However, due to the limitation of the inclination angle of the locking slider, it is still necessary to manually open the door body (open to the state where people can freely enter and exit), close (close to the lock pin on the door body and the lock block on the door frame) corresponding position)

Because the door body is heavy, it is laborious, and it also affects the speed of opening the door, which is laborious and time-consuming, causing inconvenience to the work

The driving mechanism is installed on the top of the door body. When the staff operates, they need to step on ladders, stools and other tools to operate, which is inconvenient to operate and poses a great safety hazard.
