CN2100826U - Moveable curtain - Google Patents

Abstract

The utility model relates to a moveable curtain used for sun shading. Both ends of the horizontal support bracket are fixed with shaft sleeves; a winding shaft is provided with a torsion spring. A core bar is utilized to apply the tightening force on the torsion spring, the outer end of the core bar is inserted with a shaft sleeve, both of which can not mutually rotate so that under the function of the pretightening force of the torsion spring, the curtain cloth is automatically wound up by the winding shaft. The horizontal support bracket is provided with hooks and a sucking disk which can conveniently fix the moveable curtain on the window or take the moveable curtain off. A nylon hasp and a sucking disk are arranged below the moveable curtain, and the curtain cloth can shade the sun by pulled down and fixed by the sucking disk or the nylon hasp. The fixation of the lower end of the curtain cloth is absolved so that the winding shaft can automatically wind the curtain cloth up. The moveable curtain is especially suitable for the sun-shading of the vehicle window.

Description

Moveable curtain

The utility model relates to the Moveable curtain that a kind of sunshade is used.

Space in the automobile is less, in sunlight direct projection in the summer car, can make car interior sultry, even air-conditioned automobile on sunlight direct projection people's the body, also can feel under the weather.The automotive window that has is equipped with the curtain that is difficult for pulling down, and it seems crowded unnecessary when not needing sunshade.The sunshade of some automobiles dress dark-brown glass, but the driver over against front screen can not be with dark brown, when headstock berthed on the sunny side, nobody can not turn on the aircondition in the car, does not have again and blocks, temperature can rise to painful degree very soon in the compartment.

The purpose of this utility model is to provide a kind of moveable roller shutter, so that can be fixed in window conveniently when the need sunshade, can make it roll automatically or expediently it be taken off when not needing sunshade.

Described Moveable curtain, its lateral frame two ends fixed hub, two shaft rooms are equipped with can be with the spool of the automatic rolling-in of cord, and symmetry is fixed the hook of two flutings on the lateral frame, can insert the plastic cement sucker in its groove.The cord lower end is a slice velcro fixedly, the porose sucker that embeds on it.

The structure of spool is: a hollow shaft is arranged, and fixing cord on it inserts the core bar that is with torsion spring and stifled cover in hollow axis hole.Torsion spring one end and core bar are inner to be fixed, and the other end is fixing with stifled cover, blocks up the cover plug in hollow axis hole, and can not relatively rotate with this axle.Stretch out outside the hollow shaft outer end of core bar.If hollow shaft is motionless, the core bar that inserts in its hole rotates, and has then applied lashing force to torsion spring.Torsion spring is executed the spool of lashing force in advance, insert in the axle sleeve of lateral frame, and core bar can not relatively rotate with axle sleeve with the outer end of core bar, by the effect of torsion spring pretightning force make the hollow shaft rotation with the cord rolling-in on this axle.Densely covered micropore on the cord, a side is dark pool in car, opposite side is a light color.

Above-mentioned spool can have an end of core bar only at an end cored bar, obstruction and the torsion spring of hollow shaft, and core bar is inserted in the axle sleeve, can not rotate mutually, and no core bar one end directly inserts axle sleeve with hollow shaft, and this axle can rotate relative to axle sleeve; But the also equal cored bar in hollow shaft two ends, torsion spring and stifled cover, two ends are even inserts axle sleeve with core bar.

Described roller shutter has hook on the lateral frame, can hang on the curtain rod, if no curtain rod can be loaded onto sucker in pocket for the punch head, is adsorbed on the window glass with it.Roller shutter fixs or removes all very convenient at the window place.Rolling-in was not drawn the cord lower end when cord of this roller shutter was not subjected to external force on axle, and spool rotates, and cord is pulled out, and simultaneously, torsion spring is subjected to pre-lashing force again.The cord of pulling out can be adsorbed on its bottom on glass with its sucker, if under the window another sheet velcro is arranged, also available velcro is fixed the cord of pulling out.Unplug velcro or following sucker, one looses one's grip, and torsion spring pretightning force rotating scroll is with the cord automatic rewinding.The micropore that gathers on the cord, sunlight sees through very weak, but the people can see through the shadow thing that the micropore group can see that car is outer.The cord outside is a light color, and is reflective stronger, sees through micropore and do not see in the car outside car.Described roller shutter not only is suitable for automobile to be used, and also is suitable for room window sunshade.

Fig. 1, the broken section of described roller shutter front view and spool;

Fig. 2 is that the A-A of Fig. 1 analyses and observe;

Fig. 3 is that Fig. 2 takes down the K of sucker to view.

Support 3 two ends fixed hubs 4, spool 2 is made of core bar 7, torsion spring 6, stifled cover 5, hollow shaft 8, is with torsion spring 6 and stifled cover 5 on the core bar 7, recess is left in core bar 7 the inners, and torsion spring 6 terminations embed wherein, and torsion spring 6 other ends embed in the stifled cover 5, stifled cover 5 plugs are in hollow shaft 8 holes, relative to not rotating.Core bar 7 outer end local moment tee sections insert in the axle sleeve 4, can not relatively rotate, and lateral frame 3 backs, symmetry is fixed two hooks 1, shown in Fig. 2,3, slots 12 on the hook 1, can insert sucker 11 in the groove.Cord 10 lower ends are a slice velcro 9 fixedly, and are porose on it, and Kong Zhongke embeds sucker 11.

Claims (5)

1, Moveable curtain, it is characterized in that lateral frame 3 two ends fixed hubs 4, spool 2 two ends of cord 10 automatic rolling-in can be inserted in respectively in two axle sleeves 4, lateral frame back symmetry is fixed the hook 1 of two flutings, can insert sucker 11 in its groove 12, cord 10 lower ends are a slice velcro 9 fixedly, the porose sucker 11 that embeds on it.
