Abstract
A rolling shade window screen which can tighten voile net comprises a reel and voile net reeled in the reel. It is mainly characterized in that the window screen also comprises a twisting thread wheel which is enlaced traction thread; the traction thread is connected with voile net and brings press-strain force to voile net. The pull orientation of traction thread versus voile net is opposite to the pull orientation of rolling voile net of reel. The linkage relation composed between twisting thread wheel and reel is: the reel turns towards the orientation of rolling voile net when the voile net puts the traction thread with outside force and drives the twisting thread wheel to turn through the traction thread. The structure of the unity model makes the tightening degree of voile net almost unchanged with the pulling degree of voile net, the voile net is tightened all along whether the window is in closed situation when voile net is completely drawn out or the window is in open situation when voile net is completely drawn back or the window is in half-open situation when voile net is half drawn out.
Description
Technical field
The utility model relates to the structure of screen window, but the rolling curtain type screen window of gauze rolling on a spool particularly.
Background technology
Existing screen window, particularly rolling curtain type screen window all have a spool and the gauze of rolling on spool.When windowing, spool relies on spring force rolling gauze, when closing window, relies on staff to overcome spring force and pulls out gauze from spool, and gauze is connected with a fixing device, and gauze is tensioned under the spring force effect.This rolling gauze and tensioning gauze all rely on the design feature of same spring force, has significant disadvantages: at first, if spring force is too small, be difficult to the rolling gauze, if spring force is excessive, under the effect that additional external force is arranged, for example gauze is subjected under the situation that big wind scrapes, additional external force and spring force lump together and just make gauze break away from fixing device easily, are directed at screen window and open by mistake and open; Secondly, as long as beginning rolling gauze, spring force will can't make screen window be in half-open window state with the whole rollings of gauze on spool, and shortcoming is used flexibility; Once more, this structure is difficult to realize automatically controlled automation; Have again, under the window closing state of all pulling out gauze, the spring force maximum that gauze is subjected to, after long-time the use, gauze easy deformation not only, spring is also tired easily, has influenced the application life of screen window.
Summary of the invention
The purpose of this utility model provides a kind of rolling curtain type screen window that need not spring also can the auto-tensioning gauze.
But the utility model is achieved in that the rolling curtain type screen window of auto-tensioning gauze and comprises a spool, and the gauze of rolling on spool, especially, also comprise a twisted wire wheel that links with spool, the twisted wire wheel is wound with draught line, draught line is connected to gauze and gauze is produced prefastening force, draught line is to the direction of draw of gauze, opposite with the direction of draw of spool rolling gauze, the twisted wire wheel with the interaction relation that spool constitutes is, when gauze spurs draught line under external force, and when driving the twisted wire wheel and rotate by draught line, spool rotates towards the direction of rolling gauze.During use, pull out gauze, perhaps rotate the twisted wire wheel, utilize draught line pulling gauze, screen window can be closed from spool; When windowing, spur gauze in the other direction, perhaps the counter-rotation twisted wire is taken turns, just can be with the gauze rolling on spool.Design feature of the present utility model makes the tensioning degree of gauze only be decided by the prefastening force of draught line to gauze, and the interaction relation of twisted wire wheel and spool makes the size of this prefastening force can change along with the pulling out degree of gauze hardly, that is no matter be the window closing state of all pulling out gauze, still all regain the state of windowing of gauze, perhaps only pull out the half-open window state of part gauze, gauze is tightened up all the time, thereby reaches the purpose of auto-tensioning gauze.
The utility model has the advantages that: 1, can the auto-tensioning gauze, even the external force effect such as scraping because of big wind, gauze is pulled, also keeping tensioning state; 2, screen window can be in half-open window state, uses more flexible; 3, useable electric moter drives twisted wire wheel or spool, be convenient to realize automatically controlled automation, further, can adopt the transmission mechanism of band auto-lock function between motor shaft and twisted wire wheel or spool, for example Worm and Worm Gear Driving mechanism can't be spurred gauze by the external force beyond the motor, form good wind resistance, again further, also handwheel can be installed on motor shaft, so that when having a power failure, rotate twisted wire wheel or spool by handwheel; 4, do not have the spring fatigue problem, and draught line only need guarantee that to the prefastening force of gauze gauze has certain tensile force to get final product, this prefastening force is much smaller than the tightening force of prior art medi-spring to gauze, thereby improved the durability of screen window.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Referring to Fig. 1, the utility model comprises spool 1, gauze 2 and twisted wire wheel 3.When spool 1 when the diagram direction of arrow is rotated, can be on spool 1 with gauze 2 rollings.Spool 1 is installed on the same axis 4 with twisted wire wheel 3.Axle is with bearing 5 on 4, and bearing 5 is fixed on the last side window frame 6 of screen window (, the concrete profile of in figure do not draw window frame succinct for making view).Be connected with gauze 2 through fixed pulley 8,9 from twisted wire wheel 3 draught lines of drawing 7, make that the direction of draw of 7 pairs of gauzes 2 of draught line is opposite with the direction of draw of spool 1 rolling gauze, and gauze 2 is produced certain prefastening force.As seen from the figure, twisted wire wheel 3 makes when gauze 2 upwards spurs the end of a thread of draught line 7 because of the external force effect with the interaction relation that spool 1 rotates, draught line 7 drives twisted wire wheel 3 towards the direction rotation of ordering about spool 1 rolling gauze 2, that is rotates towards the diagram direction of arrow.Like this, how many draught lines 7 is drawn out, gauze 2 just by rolling what, make the prefastening force of 7 pairs of gauzes 2 of draught line can change along with moving up and down of gauze 2 hardly, no matter where gauze 2 is pulled to, and gauze 2 is all the time at the prefastening force effect lower automatic tensioning of draught line 7.
Further, for fear of in the process of spool rolling gauze, perhaps pull out the process of gauze from spool, because the instantaneous velocity that gauze moves increases along with the increase of gauze coiling thickness, reduce along with the minimizing of coiling thickness, be directed at the prefastening force generation significant change of draught line to gauze, present embodiment offers screw-shaped coiling ditch 10 on twisted wire wheel 3, draught line 7 is absorbed in the coiling ditch 10, take turns the direction of rotation of 3 rolling draught lines along twisted wire, the radius of spin of coiling ditch 10 reduces continuously.Like this, in spool 1 rolling gauze, will increase along with the increase of gauze 2 translational speeds from the instantaneous velocity of twisted wire wheel 3 draught lines of pulling out 7, otherwise, when when spool 1 is pulled out gauze, the instantaneous linear velocity that twisted wire is taken turns 3 rolling draught lines can reduce along with gauze 2 reducing of translational speed again, thereby the prefastening force that can guarantee 7 pairs of gauzes 2 of draught line better can not change along with moving of gauze 2.
In the present embodiment, be divided into two from twisted wire wheel 3 draught lines of drawing 7, after two draught lines were walked around two fixed pulleys 8,9 respectively, symmetry was fixed on the both sides on the gauze 2 termination widths.So make the pulling force of draught line 7 to act on more equably on the gauze 2.Further, also be fixed with the position that 11, two draught line symmetries of trimming strip are fixed on close trimming strip 11 two ends in the termination of gauze 2.Trimming strip 11 makes that not only the pulling force of 7 pairs of gauzes 2 of draught line is more even, and plays the effect of handle, is convenient to staff and spurs gauze up and down by gripping trimming strip.Trimming strip 11 can be made with aluminium extruded sections, plastics.
Above embodiment is only for understanding the utility model, be not to restriction of the present utility model, those of ordinary skill in the art can also have multiple variation or distortion on this basis, and for example, the spool 1 among Fig. 1, twisted wire wheel 3, draught line 7, fixed pulley 8,9 all can be hidden in the window frame; Left and right sides window frame can be made into the clip slot shape, and the right and left of gauze 2 is hidden in the clip slot; Two ends at trimming strip 11 also can be provided with pulley, and pulley is slided along two side window frames; Between trimming strip 11 and bottom side window frame, also fixing devices such as hook, magnetic sealing strip can be set, so that tie down gauze 2 better; Twisted wire wheel 3 also can be installed on two axles respectively with spool 1, and by gear drive realization interaction relation, also can drive twisted wire wheel 3 and spool 1 respectively with two stepper motors, by digital-control circuit two stepper motors are carried out 2-axis linkage control again, twisted wire wheel 3 and spool 1 are rotated according to interaction relation described in the utility model, also can consider to adopt wireless or infra-red remote control the control of motor; Total shown in Figure 1 also can laterally be placed, and becomes the horizontal push-pull type screen window, and and so on, variation that all are equal to or modification all belong to protection domain of the present utility model.
