Abstract
A hanging-type reel curtain is provided, which is characterized in that: the invention comprises a curtain bracket, a reel moved by a drive mechanism arranged inside the curtain bracket inside, a stop dog arranged on the interior surface and tightly leaning against the reel, a reeling rope guide device arranged beside the reel and corresponding with the stop dog, a reeling rope with one end fixed on a reel away from the stop dog, and the other end connected with the curtain through the reeling rope guide device. Compared with the prior art, the invention has the advantages of adapting to different sizes of regular hanging-type reel curtains, simple structure, no restricting possible design expansion of hanging-type reel curtains, and increasing space of technical functions.
Description
Technical field:
The present invention relates to a kind of curtain mechanism.
Background technology:
The kind that curtain is general has cord, venetian shutter, pleat curtain etc., they generally all have the two ends suspension line on the whole, wherein an end is fixed on the spool, the other end is fixed on the free end of spool, can open normally and roll for guaranteeing suspension type reel spindle window curtain, no matter on impression, still from mechanical aspects, all need to guarantee the well-regulated winding of serving energy, and the phenomenon that do not interweave, for realizing above-mentioned purpose, some technology is to do the synchronous linear motion by rotating shaft on the rotational direction, for achieving the above object, spool need be processed into shape of threads, this kind technical pattern complexity, and, the length of spool will have the twice of the length of the spool section of twining full serving at least, has limited the possible expansion design of suspension type reel spindle window curtain virtually, increase the space of technical functionality.In order to overcome the defective of technology in this, number of patent application discloses a kind of suspension type reel spindle window curtain technology for the european patent application of " 0554212 ", this technology by spool, be fixed on axis on the spool, prevent that the device that axis interweaves from constituting, prevent device that axis interweaves by the pivot shoulder, be fixed on the axis guide device that asessory shaft on the pivot shoulder is positioned at the asessory shaft next door and constitute, spool is connected on the asessory shaft.During work, axis is under the guide effect of axis guide device, soon axis twine full asessory shaft and under the effect of pivot shoulder, be wrapped on the asessory shaft the tight dust of axis together, afterwards, axis continues to be wrapped on pivot shoulder and tight dust that coil axis on pivot is takeed on, this axis is under the effect of its tension force, get into pivot shoulder and tight dust between that coil axis on the pivot shoulder, axis on the asessory shaft is moved outward, axis on the asessory shaft is moved toward spool in an orderly manner, like this, spool just need not relatively move axis is wrapped on the spool regularly.Though this kind technology has solved the defective of prior art, but, because the prerequisite that axis is wrapped on the asessory shaft regularly is that axis has enough tension force, and, axis has certain diameter, like this, axis can be got between pivot shoulder and tight dust that coil axis on pivot is takeed on, and general suspension type reel spindle window curtain, particularly, small-sized suspension type reel spindle window curtain is subjected to the restriction of the weight of curtain, the tension force of its axis and diameter are all little, often do not reach to get into the tension force required between pivot shoulder and tight dust that coil axis on pivot is takeed on and the requirement of diameter, have so just limited effective scope of application of this technology.
Summary of the invention:
That goal of the invention of the present invention is to provide is a kind of suspension type reel spindle window curtain that can be applicable to different sizes of regular, simple in structure, can not limit the possible expansion design of suspension type reel spindle window curtain and increase the suspension type reel spindle window curtain in the space of technical functionality.
The present invention is achieved in that by Curtain rod, be arranged on the spool that is driven by transmission mechanism in the Curtain rod, be arranged on inner surface on the spool abuts against block on the spool, is arranged on spool other the serving guiding device corresponding with block, an end and is fixed on away from the serving on the spool of block, the other end and constitutes through serving guiding device and the serving that is connected with curtain.During work, drive lower winding shaft at transmission mechanism rotates relative to block, serving is wrapped on the spool, under the guide effect of serving guiding device, near on the spool of block soon a circle adjacent enclose the land and twine the serving of multi-turn, and, the serving of up-to-date winding leans against on the block, spool is rotated further, the serving from the serving guiding device below the block is not owing to there be stopping of obstacle, serving can be wrapped on the spool at the lateral surface of the serving circle of close block, when this is wrapped in serving on the spool turns to spool top with spool block place, under the extruding of the axial compression power of block, the serving circle can move toward the direction of spool away from block, makes serving be wrapped in spool regularly.Because having adopted the spool with respect to motion above spool is static block, make the serving of guiding device need not want tension force just can be wrapped on the spool by adjacent serving circle in front, can just can make by the axial compression effect of block again simultaneously the serving that is wrapped on the spool simultaneously vertically, mobile regularly.
For spiral successfully is wrapped on the spool, the position of coming out for the serving of serving guiding device before the position of block.Further, the preceding distance of coming out for the serving of serving guiding device of block is not less than the diameter of serving.
Be wrapped in the process of spool at serving, for the serving circle that is wrapped on the spool is successfully moved in the direction of spool fixed point toward serving, have at least one section diameter to diminish gradually on the spool of winding serving, be not less than the diameter of back spool along the diameter of serving front spool on the spool of the winding serving of the direction of spool fixed point along the direction of serving at the spool fixed point.
The present invention compared with the prior art, because having adopted the spool with respect to motion above spool is static block, therefore, have the suspension type reel spindle window curtain that can be applicable to different sizes of regular, simple in structure, can not limit the possible expansion design of suspension type reel spindle window curtain and increase the advantage in the space of technical functionality.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
Now in conjunction with the accompanying drawings and embodiments the present invention is described in further detail:
As shown in the figure, the present invention by Curtain rod 1, be arranged on the spool 2 that drives by transmission mechanism in the Curtain rod 1, the soffit that is arranged on spool 2 tops abuts against block 3 on the spool 2, be arranged on that serving guiding device 4, an end corresponding with block 3 below the spool 2 is fixed on the spool 2 away from block 3, the other end constitutes through serving guiding device 4 and the serving 5 that is connected with curtain, block 3 is connected on the bearing 6 of spool 2.The position 4a that comes out for the serving of serving guiding device 4 before the position of block 3.Further, the distance A of the preceding position 4a that comes out for the serving of serving guiding device 4 of block 3 is not less than the diameter of serving 5.Have at least the diameter of one section B to diminish gradually in the direction of spool 2 fixed point 2a (comprising that certainly spool 2 is these special cases of diminished shaft) on the spool 2 of winding serving 5, be not less than the diameter of back spool 2 along the diameter of serving 5 front spool 2 on the spool 2 of the winding serving 5 of the direction of spool 2 fixed point 2a along serving 5.
