Description
Technical field
The utility model relates to a kind of lift venetian blinds.
Background technology
The tradition sun blind are made up of component such as blind sheet, upper beam, underbeam, curtain sheet elevation and subsidence regulating device, curtain sheet corner adjusting devices.The blind sheet is provided with two holes, and the lifting stay cord is through in this two hole of blind sheet, relies on operation lifting stay cord transmission metal worm screw, worm gear to make the lifting of blind sheet; Rely on and regulate the rotational angle that angle pole is regulated the blind sheet.When the blind sheet was in level, sun blind were in full open position; When the blind sheet is in when tilting at an angle with horizon, then sun blind are in half-open semi-closure or closure state.Because the blind sheet is provided with the hole,, can not shelters from the light leak that the blind film perforation is produced fully, thereby influence the shaded effect of sun blind even sun blind are closed fully.Because this two covers adjusting device is finished lifting, the rotation of regulating the blind sheet by the operation of lifting stay cord, corner stay cord or angle pole respectively,, influenced the succinctly beautiful of sun blind outward appearances again so both increased cost of production, be awkward.
A kind of need one cover adjusting device has been proposed among the China utility model patent ZL200920150083.7, the transmission of lifting stay cord operation can be finished the sun blind that sun blind lifting and blind sheet angle are stirred, these sun blind comprise the blind sheet, the upper beam package system, underbeam, the lifting stay cord, the front and back side of blind sheet, selvedge ladder band is equipped with in the corresponding position, hole of blind sheet, an end of beam package system is equipped with the side seal lid thereon, the other end is equipped with rope locking device, between side seal lid and rope locking device, transverse axis is housed, the top that its lifting draws high is contained in the rope locking device, on transverse axis, the adjuster Connection Block is equipped with in the corresponding position of blind sheet, on transverse axis, two-way rope drum is housed in the adjuster Connection Block, side at two-way rope drum is equipped with drive, both sides are contained in respectively on the drive before and after the upper end of selvedge ladder band, and curtain sheet connection cord is housed on two-way rope drum.
This utility model has solved traditional sun blind substantially and has regulated inconvenience and cost problem of higher, compared with former sun blind, curtain film perforation light leak also reduces to some extent, but also has the improved aspect of some needs, still bigger as the hole on the blind sheet, still have the possibility of light leak; Curtain sheet connection cord is wrapped on the rope drum, when descending operation, have knotting may, in case knotting then have a strong impact on the use of sun blind; Frictional force between connection cord and rope drum is bigger, operate light inadequately, and when operation noise big; The structure of rope drum has taken most of space in the upper beam package system, has made obstacle for motor is installed in the upper beam package system with the further improvement that realizes intelligent sun blind.
