CONCEALED TYPE LIFTING CONTROL MECHANISM FOR VENETIAN BLIND |
摘要 |
A concealed type lifting control mechanism installed in a Venetian blind and adapted to control lifting of the lift cord of the Venetian blind comprises at least two take-up reel sets that provide a predetermined spring release force and are connected to the lift cord to impart a roll-up prestress to the lift cords for taking up the lift cords, a synchronizing transmission unit coupled to the at least two take-up reel sets for enabling the at least two take-up reel sets to be work synchronously, and a positioning device set provided between the take-up reel sets and moved between an engagement position and a release position to determine the provision of the roll-up prestress, for enabling the lift cords to be moved to adjust the Venetian blind to the desired elevation.
