Screen door locking manual electric switching device

Abstract

The invention discloses a shielded gate locking manual-electric operation switching device. The switching device comprises an electric shaft, an electric driving part, a manual driving part and a connection shaft pushing component, wherein the electric shaft is provided with a movable connection shaft and rotatably supported on a shielded gate; the electric shaft is in transmission connection with a gate locking device of the shielded gate, so that the electric shaft drives the gate locking device to act when being driven to rotate, and opening and closing of the shielded gate are achieved; the manual driving part penetrates through a shield-sealing material layer of the shielded gate; the electric driving part is in transmission connection with the electric shaft; the connection shaft pushing component is connected with a connection shaft, so that the connection shaft pushing component acts to enable the connection shaft and the manual driving part to be separated or connected; and when the electric driving part does not act, the connection shaft pushing component acts so that the connection shaft and the manual driving part can be connected, and then the manual driving part drives the electric shaft to rotate. According to the shielded gate locking manual-electric operation switching device, not only can no-spare-stroke switching of manual gate opening and closing be ensured, but also convenient switching of manual operation and electric operation can be ensured.

Description

technical field [0001] The invention relates to a manual and electric switching device for locking a screen door. Background technique [0002] At present, the existing shielding door adopts the dual-axis design of electric shaft and manual shaft, which separates the shaft that can play the shielding function and can be manually operated from the electric shaft, and the two shafts are fixed to each other or separately, so that during normal work, the electric mechanism The axis of the shaft rotates and the shaft used to open the door manually through the shielding layer does not rotate, so that the shielding sealing material that ensures the shielding effectiveness is in a static state and does not wear out, prolonging the use time that meets the shielding effectiveness; at the same time, a boundary limit is added between the two shafts The structure, when the electric part fails or the power fails, the personnel in the room can also open the screen door by turning the inner...

Problems solved by technology

[0003] But in this case, there is a spare stroke of stroke length in the manual door opening and closing switching process, which is inconvenient to use

If it is necessary to ensure that there is no free stroke switching between manual door opening and closing, manual and electric switching will be very inconvenient
