Abstract
The utility model relates to an opening and closing device for a window curtain, which mainly comprises a box body, a rotary wheel arranged at one end of the box body, a controlling wheel, a friction wheel and an auxiliary friction wheel, wherein, the controlling wheel, the friction wheel and the auxiliary friction wheel are arranged at the other end of the box body; the surface of the controlling wheel is provided with two annular grooves; a tense closed hauling cable is arranged in the external groove of the controlling wheel and on the rotary wheel, and a controlling cable is arranged in the internal groove; the box body is provided with a sliding bar inside horizontally along a longitudinal direction, and a hanging ring on the internal side of the sliding bar is connected with the hauling cable via a connecting cable. The utility model solves the disadvantages that because the hauling cable is easy to loose and the pulley is frequently derailed, clamped, etc., the existing curtain frame is inconvenient to operate, and is easy to damage.
Description
The utility model relates to a kind of switching device of curtain, is a kind of curtain rod arm specifically.
In the prior art, the curtain rod arm that is used to open curtain is made up of guide rail, pulley, suspension ring and control wire.One of its shortcoming is that the horizontal rope that is used to draw is loose easily; cause curtain opening be inconvenient to reach not attractive in appearance; the another one shortcoming is owing to a plurality of pulleys rolling traction curtain on guide rail, the derailing and the clamping stagnation of pulley usually can occur, causes the damage of curtain rod arm even.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and provides a kind of unlatching convenient, flexible, is not prone to the curtain rod arm that makes things convenient for of derailing and catching phenomenon.
For finishing above-mentioned purpose, the utility model provides a kind of curtain rod arm that makes things convenient for, it comprises a box body 1, its special character is: the end in described box body 1 is installed the control wheel 9 that a surface is provided with two annular grooves, the other end in box body 1 is installed the moving runner 2 that a surface is provided with an annular groove, the pull rope 3 of a sealing and tension is housed between above-mentioned control wheel 9 and moving runner 2, one end of this pull rope 3 is positioned at the groove on the moving runner 2, the other end is positioned at a groove on the described control wheel 9, the control wire 18 of a sealing is housed in another groove on described control wheel 9, a side that is positioned at control wheel 9 in described box body 1 is installed a surface and is provided with two annular projections 21 and 22 and press the friction pulley 10 of pull rope 3 and control wire 18, at the opposite side that is positioned at control wheel 9 the secondary friction pulley 8 that a surface is provided with an annular projection 20 and presses control wire 18 is installed, in described box body 1, longitudinally be horizontally installed with slide bar, slide bar is provided with a plurality of suspension ring, and big suspension ring of its inboard respectively link to each other with pull rope 3 by a connection cord.
The wheel that control described in above-mentioned curtain rod arm wheel 9, friction pulley 10 and secondary friction pulley 8 should adopt the bigger material of various frictional force to make, with the rubber wheel effect for well.
Slide bar in the above-mentioned curtain rod arm can be a slide bar, also can be two slide bars (11), (17), and they constitute a kind of single open-type curtain rod arm and a kind of double-open type curtain rod arm respectively.
Accompanying drawing has been described a preferred embodiment of the present utility model.
Fig. 1 is the structural representation of a preferred embodiment of the utility model;
Fig. 2 is that this embodiment removes the later plan structure schematic diagram in box body top.
Know that referring to Fig. 1, Fig. 2 this makes things convenient for curtain rod arm to have a box body 1, moving runner 2 is installed in the end in the box body, which is provided with an annular groove.The other end that control wheel 9 is installed in the box body, which is provided with two annular grooves, pull rope 3 one ends of sealing and tension are arranged in the groove on moving runner 2 surfaces, the other end is arranged in control wheel 9 superolateral grooves, the control wire 18 of sealing is installed in the groove inboard on the control wheel 9, friction pulley 10 surfaces that are installed in control wheel one side are provided with two annular projections 21 and 22, they respectively be located at control wheel 9 on two annular recess match, press control wire 18 and pull rope 3, the secondary friction pulley 8 that is installed in control wheel 9 opposite sides is provided with an annular projection 20, this projection matches with the groove that is located at control wheel 9 inboards, the opposite side that presses control wire 18, two slide bars 11 and 17 outer end are fixed on the box body 1, the inner connects with box body by support bar 5 and 19 respectively, be respectively arranged with a plurality of suspension ring 12 and 16 on two slide bars 11 and 17, big suspension ring 13 of its inboard with 15 respectively by connection cord 14 with 7 be fixed on pull rope 3 on bail 4 link to each other with 6.Described control wheel 9, friction pulley 10 and secondary friction pulley 8 all adopt rubber wheel, so that there is bigger frictional force on its surface.
During use two casements are installed on the suspension ring, control wheel 9 are rotated, and then pull rope 3 is rotated, again by bail 4 and 6, connection cord 14 and 7 and big suspension ring 13 and 15 traction curtain openings by pulling control wire 18.
If a slide bar 17 in the foregoing description, suspension ring 16, big suspension ring 15, bail 6, connection cord 7 are removed, and with another root slide bar 11 lengthenings, then can be with the curtain rod arm of a single open-type structure of above-mentioned curtain rod arm repacking.
Can find out that in conjunction with above-described embodiment the utility model has following advantage compared to existing technology:
1, the pull rope owing to sealing is tightened up and is installed on moving runner and the control wheel, thereby this pull rope can not be inconvenient to reach not attractive in appearance because of the loose curtain opening that causes all the time;
2, realize the unlatching of curtain with pull rope, control wheel, friction pulley and control wire, derailing, catching phenomenon can not occur, improved the quality of curtain rod arm;
3, flexible operation, convenience, laborsaving.
