Description
The utility model relates to a kind of device of door and window hanging curtain, particularly relates to a kind of unlatching and closed roller blind device of curtain for door or window.
Existing door and window roller shutter mostly is by support, supporting base, positioner, roller shutter pipe and cord to be formed, supporting base is provided with the pearl cable pulley that matches with the pearl rope, when unlatching and closed roller shutter, only with hand pulling pearl rope, pearl cable pulley on the moving supporting base of pearl strap and the roller shutter pipe and the cord that are connected on the bearing support rotate, at this moment cord just can move up or down on demand, stops drag the pearl rope, and cord just can stop on the residing at that time position.But because bearing support is to be connected with screw with supporting base, therefore accuracy is installed and has relatively high expectations, forbidden, make pearl cable pulley and pearl rope join the fashionable deviation that has, and cause the pearl rope to spur to have some setbacks or block pearl otherwise easily cause positioner to locate with the pearl cable pulley; Because pearl cable pulley and supporting base are connected as a single entity, and the gear teeth of pearl cable pulley are " L " type, when spurring the pearl rope, are easy to take off groove again; Add after the dismounting roller shutter all needs the screw on the roller shutter supporting base unscrewed, just can unload, it is very inconvenient therefore to dismantle roller shutter.
The purpose of this utility model provides a kind of roller shutter and spurs hand roller shutter smooth and easy, convenient disassembly, and its only with hand is stirred the start and stop lever on the supporting base, just detachable roller shutter.
For achieving the above object, the utility model hand roller shutter by supporting base, be installed in the positioner on the supporting base, the pearl rope that matches with the pearl cable pulley, roller shutter pipe and cord are formed, the gear teeth of the pearl cable pulley on the supporting base are groove shaped, and the inboard of pearl cable pulley is provided with locating piece, torsionspring and breach wheel, and breach wheel one side is provided with breach, another side is provided with the boss of band through hole, described breach wheel is nested on the locating piece, and supporting base is provided with dead bolt, and dead bolt can be locked on the boss of breach wheel; The inboard and the bottom of another supporting base are provided with the hole, have start and stop lever to place in the supporting base and reach outside the hole of supporting base bottom, can place the pushing block that expansion link is housed in the supporting base inboard aperture.
Described start and stop lever and supporting base are interference fit, and can stir forward or backward in supporting base, and described start and stop lever can promote to place the expansion link in the pushing block of supporting base inboard aperture to move forward or backward.
Have projection on the locating piece of described pearl cable pulley inboard, torsionspring is provided with screens, and the breach on the breach wheel is nested between the screens of projection on the locating piece and torsionspring.
The utility model hand roller shutter is because the gear teeth of pearl cable pulley are groove shaped, and when making pulling pearl rope, the pearl rope is difficult for taking off groove and can prevents the card pearl; Again owing to be provided with the locating piece that may be stuck between the torsionspring, and adopting the dead bolt of automatic locking on the breach wheel on the supporting base in the inboard of pearl cable pulley, therefore not only roller shutter accurate positioning, the pulling of pearl rope is smooth and easy, and fitting operation is simple and convenient; Simultaneously because another supporting base is provided with start and stop lever and the pushing block of expansion link is housed, when making the dismounting roller shutter, only need start and stop lever is stirred to expansion link one end, expansion link just can correspondingly move, promptly detachable roller shutter, so simple in structure and convenient disassembly.
Below in conjunction with accompanying drawing the utility model hand roller shutter is described in further detail.
