Description

Wobble type device for drawing curtain

The utility model relates to a kind of hand-rail type draw-back curtain bobbin winoler.

Curtain method for opening and closing in known technology on the installation window is only limited to pulling cotton rope or directly tearing curtain it is opened or closed.Its weak point is easy to cotton rope be broken or casement is shut down owing to the problem in curtain rod design or the manufacturing; Because sagging cotton rope, causes even more serious that 4 sagging stay cords of winding, especially double-layer window curtain twine between rope and the rope without any anchor point, causes inconvenience when draw-back curtain.

The purpose of this utility model is to overcome the prior art weak point and a kind of hand-rail type draw-back curtain bobbin winoler is provided.

The purpose of this utility model realizes by following measure:

Architectural feature of the present utility model is to be

Shape has screw hole on the cubical big plane, there is aperture in the centre, 2 planar central all have the main body of through hole in addition, there is aperture at the center of being equipped with between big plane and mid-plane, three step through-holes of keyhole and through hole, the top is the interior lines wheel of concave arc shape, the both sides that mid-plane and the 3rd interplanar are equipped with the center are to be keyhole in the middle of the unthreaded hole, the top is the outside line wheel of concave arc shape, outside line wheel unthreaded hole on one side be sleeved on be installed in the 3rd plane through hole in the spindle nose of the foraminate axle sleeve in centre on, there is its outer peripheral face of aperture to have to be complementary the key cover of of bonding in the middle of being equipped with in the keyhole of two lines wheels, big plane with it, the interior lines wheel, be equipped with in all apertures on key cover and the axle sleeve

Shape, the solid dead rocking handle thereon of key cover, the perpendicular both sides inside edge of the opening of main body respectively is equipped with wire guide plate, the outside of main body be covered with Contraband shape, mid-plane has with wire guide plate on the cover cap in corresponding hole, hole.

Can stud with the keyhole of one deck rubber face internal and external line wheel and the of bonding of key cover on the top cancave cambered surface of internal and external line wheel of the present utility model can be square type spline, also can be hexangle type, can also be that gradually open form is spent.

The structure of wire guide plate provided by the utility model can be vertically two-layer at the two symmetrical square holes of lead frame, every layer near the hole wall both sides axle sleeve that can pass the square guide hole of cotton rope in the middle of adorning on it and form with little pedestal is housed accordingly, also can be the circular guide holes that two its symmetrical holes one-tenth fillets are arranged on lead frame.

Advantage of the present utility model is to use and is difficult for part a line flexibly, avoids simultaneously casement is shut down; Use the utility model can not cause the rope and the wrapping phenomena draw-back curtain easily of restricting.

The embodiment that the utility model is provided is described in further detail in conjunction with the accompanying drawings:

Example structure of the present utility model is to be

The cubical both sides, big plane as base of shape have respectively that there is aperture in the centre of 2 screw holes, in addition one on two planes are as the main body 1 that all has through hole as lateral wall, its center in next door.The center of being equipped with, space between base and next door have aperture be successively keyhole and through hole three step through-holes, the top is the interior lines wheel 2 of concave arc shape.The both sides that the center is equipped with in space between next door and lateral wall are to be keyhole in the middle of the unthreaded hole, the top is the outside line wheel 4 of concave arc shape, outside line wheel unthreaded hole on one side is sleeved on screw 10 and is packed in the lateral wall through hole, on the spindle nose of middle foraminate axle sleeve 5, can stud with the rubber layer 15 that skids when one deck prevents the cotton rope moving on the top cancave cambered surface of internal and external line wheel, there is its outer peripheral face of aperture to have to be complementary the key cover 3 of of bonding in the middle of being equipped with in the keyhole of two lines wheels with it, the of bonding of the keyhole of internal and external line wheel and key cover can be a square type spline, it also can be hexangle type, can also be open form spline gradually, base, interior foreign steamer, be equipped with one in all apertures on key cover and the axle sleeve

Key is applied mechanically bearing pin 9 solid dead rocking handles 6 thereon in the time of shape, the wire guide plate that tightens up with screw 11 respectively is equipped with at the perpendicular place, both sides of the edge of the opening of main body, its structure is two-layer vertically in the two symmetrical square holes of lead frame 8, every layer of close hole wall both sides are equipped with accordingly and are adorned on it and the middle wire wheel axis cover 14 that can pass the square guide hole of cotton rope of composition with little pedestal, also can on lead frame 8a, have two symmetrical, the circular guide holes of hole one-tenth fillet, the outside of main body are covered with Contraband shape, there are 4 through wires holes at 12 places of mid-plane, at 13 places are cover caps 7 of an alignment pin in the dowel hole that can insert on the body.

The utility model using method is: bobbin winoler is screwed on wall below curtain rod one end, and the inside and outside two-layer cotton rope that vertically gets off from the curtain is wrapped in respectively on the internal and external line wheel of bobbin winoler.Desire opens and closes the internal layer curtain, and rocking handle is inwardly pushed, and the key cover broke away from outside line wheel band key part when the key cover meshed with the interior lines wheel, and suitable (or contrary) hour hands shake rocking handle, thereby open or close the internal layer curtain; Desire opens and closes outer curtain, and rocking handle is outwards pulled out, and the key cover broke away from interior lines wheel band key part when the key cover meshed with the outside line wheel, and suitable (or contrary) hour hands shake rocking handle, thereby open or close outer curtain.
