Description
Technical field
The present invention relates to sun blind, is a kind of without the stay cord sun blind specifically.
Background technology
There are characteristics easy to use without the stay cord sun blind, more and more be subject to liking of people.In the market a lot of without stay cord sun blind kind, such as publication number is the disclosed utility model patent of CN202611547U, it discloses a kind of without stay cord sun blind retracting device, it comprise set up separately for being wound around the line wheel of stay cord, one end of stay cord is connected with the base of sun blind body, and the other end is fixedly connected on drum, and drum is fixedly connected with the capstan that scroll spring is installed, the inboard of scroll spring is fixed on capstan, and the outside is fixed on secondary guide wheel.
Existing " without stay cord sun blind retracting device " patent that can be CN202611547U by similar publication number without the stay cord sun blind realizes the automatic lifting of sun blind, and by manually sun blind down being pulled out.Without the stay cord sun blind by the stay cord automatic winding in the reel of retracting device, with tradition, stay cord sun blind contrasts is arranged, without the stay cord sun blind, use more conveniently, profile is more attractive in appearance.
The existing shortcoming without the stay cord sun blind is: still need to pull the ladder rope to carry out the angle of adjusting louver by hand rotation blinds governor motion, complex structure and use are convenient not.
Summary of the invention
The purpose of this invention is to provide a kind of without the stay cord sun blind, it has the device of automatic adjusting louver angle, can effectively reduce and prevent has rope formula shutter product can cause stay cord winder neck as tradition, increase the safety that product is used, have simple in structure, safe, attractive in appearance and use characteristics very easily.
Purpose of the present invention can realize by following technical solution.
A kind of without the stay cord sun blind, comprising:
Upper rail, comprise a flute profile top box and the shell fragment pull rope mechanism be fixedly installed in top box and at least two rotaring wheeling base groups, and the trench bottom rotaring wheeling base group position of top box has the stay cord hole;
Lower rail, isometric with top box and align metal tube or a groove;
Vane group, comprise the blade that terraced rope and multi-disc and top box are isometric, and the upper and lower end of ladder rope connects respectively rail and lower rail, and what each blade was separated is connected with the ladder rope; On each blade, the stay cord hole site of corresponding top box is provided with through hole;
Stay cord, an end of stay cord is fixed and is wound in the shell fragment pull rope mechanism of rail, and the other end of stay cord is stretched out and is connected in lower rail through after the through hole of each blade by the stay cord hole of top box through the rotaring wheeling base group; The pulling force of shell fragment pull rope mechanism is a bit larger tham the gravity of lower rail and vane group.
Special feature of the present invention is:
The rotaring wheeling base group comprises rotaring wheeling base and runner, rotaring wheeling base is the rectangular housing of upper and lower opening, side wall upper part at rotaring wheeling base is provided with the notch type axle bed, runner is provided with rope groove and wedge shape ladder grooving, the two ends of runner are provided with rotating shaft, runner is arranged in rotaring wheeling base by the axle bed of rotating shaft and rotaring wheeling base, and the sidewall of rotaring wheeling base is provided with the rope hole; Article one, the stay cord king pin is plugged in the below of runner in rotaring wheeling base.
Stay cord enters through the rope hole of rotaring wheeling base group the rope groove of walking around runner in rotaring wheeling base after the stay cord king pin turns to and passes by the under shed of rotaring wheeling base and the stay cord hole of upper rail.
The upper end of ladder rope is mounted in the wedge shape ladder grooving of runner through the stay cord hole of upper rail and the under shed of rotaring wheeling base; Pull rope mechanism comprises shell and is located at least two cover cord winders in shell, is provided with the driven wheel installation shaft in shell and derives the gear installation shaft.
Cord winder comprises scrollwork shell fragment and intermeshing driven wheel and derives gear, one side disjunctor of driven wheel is provided with coaxial driving shaft, the one side disjunctor of deriving accordingly gear is provided with coaxial derivation axle, the scrollwork shell fragment is placed on driving shaft, its inner termination is fixedly connected with driving shaft, its external end head is pulled out with deriving axle and is fixedly connected with, and at driven wheel or the opposite side disjunctor of deriving gear, is provided with reel, and reel is for being wound around stay cord.Driving shaft and driven wheel central authorities have axis hole and are movably installed in shell by this axis hole and driven wheel installation shaft.
Deriving axle, derivation gear and reel central authorities has axis hole and is movably installed in shell by this axis hole and derivation gear installation shaft.
The most basic structure is:
The rotaring wheeling base group is provided with two and be individually fixed near the both ends in top box, described shell fragment pull rope mechanism is fixed between two rotaring wheeling base groups in top box, there is the above cord winder of two covers in the shell fragment pull rope mechanism, article two, stay cord divides both sides respectively through rotaring wheeling base group and vane group, one end of stay cord connects lower rail, and the other end of stay cord curls on the reel of the wherein a set of cord winder that is connected in the shell fragment pull rope mechanism.
During use, firmly lower rail is pulled down, lower rail drives stay cord, each blade of vane group is progressively put on display, after being pulled out to appropriate location, vane group stops, runner with the rotaring wheeling base group when upper end of ladder rope starts during this time rotates, one side make each blade all to turning over and mutually being close to the vane group that becomes shading, no longer rotate with the runner of rotaring wheeling base group the upper end of rear ladder rope; At this moment the scrollwork shell fragment of cord winder is partly drawn and is rolled onto the derivation axle, and the pull-back forces that the scrollwork shell fragment produces and the gravity of vane group and lower rail and the resistance that stay cord is subject to runner reach equilibrium state.
While adjusting each blade angle of vane group, upwards slightly hold up lower rail with hand, instantaneous time, the pull-back forces that the scrollwork shell fragment of cord winder produces is greater than the gravity of vane group and lower rail and the resistance that stay cord is subject to runner, stay cord is pulled back, rotate with the runner of rotaring wheeling base group the upper end of ladder rope, makes each blade all to returning, translate into the vane group that certain angle becomes the part shading, and even each blade is all to returning the vane group of turning over and become shading.Like this, by operation downward or upward lower rail, the just suitable shading angle of the blade of adjustable vane group.
The outstanding substantive distinguishing features of the present invention is with showing to improve: the stay cord that the present invention does not expose, can effectively reduce and prevent has rope formula shutter product can cause stay cord winder neck as tradition, increase the safety that product is used, more without angular adjustment apparatus, just can realize the blade angle adjustment of vane group, there is effect simple in structure, safe, attractive in appearance and easy to use.
