Description
Technical field
The utility model belongs to the screen window field, especially relates to a kind of screen window that utilizes the tensile force backrush.
Background technology
The window screening automatic rewinding of traditional backrush formula sliding sash with disappearing screen window all is to realize by the torsion that is contained in the spring in the window screening reel; Shown in Fig. 4-5; When downward pulling window screening 3, window screening reel 8 drives sliding connectors 12 and rotates to a direction, because of sliding connector 12 is connected with an end of spring 6 and is fixed together; So just force spring 6 distortion to produce torsion, when opening window screening 3 reel 8 at a following window screening 3 rollbacks of the torsion of spring 6 to 1 li in yarn box.
This window screening backrush device accessory is many, assembles more loaded down with trivial detailsly, and at first, it is mounted in the window screening reel, so just makes the window screening reel will have enough spaces to hold this device, and drum diameter can't dwindle, and it is little to cause the yarn box to hold the yarn quantitative change.Secondly, the backrush shaft diameter that inserts in the middle of the spring requires very high, if diameter is thick excessively, can cause the spring twist angle to diminish, and the window screening stretching distance is obviously shortened, if diameter is meticulous, can cause spring distortion in distort process, to occur, and window screening can't normally be stretched.Once more, that part of length that the backrush axle that inserts in the middle of the spring is reserved in the window screening outside receives the restriction of yarn box, causes the twist angle of spring also significantly to be restricted.At last, there is frictional force to produce between the spring steel wire when spring produces torsion and discharges torsion in distortion, causes spring to descend application life.
The utility model content
The purpose of the utility model is the deficiency that overcomes prior art, provide a kind of simple in structure, assembling is simple, long service life and utilize the screen window of tensile force backrush.
The technical scheme of the utility model is: a kind of screen window that utilizes the tensile force backrush; Comprise window screening, reel, axis of traction, traction element and spring, a side of window screening is fixed and is wrapped on the reel, in the both sides of reel an axis of traction is installed at least; Axis of traction drives the reel rotation; One end of traction element is fixed and is wrapped on the axis of traction, and the other end of traction element links to each other with spring one end, and the other end of spring is fixed.
Further, said axis of traction links to each other with reel is coaxial, or between said axis of traction and the reel through gear drive.
Further, said traction element is one or more in rope, wire, the software ribbon.
Further, the bottom of said window screening also is provided with handle.
Further, said reel periphery also is provided with the yarn box, and the periphery of axis of traction, traction element and spring also is provided with slideway.
Further, said slideway also is provided with groove near a side of window screening, and the both sides of the edge of window screening place in the groove.
Further, the fixed end of said spring is fixed on chute wall, wall or the forms.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme; Change the dependence of screen window tradition automatic rewinding and be contained in the defective that the spring torsion in the window screening reel is realized; A kind of method that relies on springs power to realize the screen window backrush has been proposed; This utility model has advantages such as simple in structure, easy to assembly, long service life.

The specific embodiment
Shown in Fig. 1-3,
The technical scheme of present embodiment is:
A kind of screen window that utilizes the tensile force backrush; Comprise window screening 3, reel 8, axis of traction 4, traction element 5 and spring 6, a side of window screening 3 is fixed and is wrapped on the reel 8, in the both sides of reel 8 axis of traction 4 is installed at least; Axis of traction 4 drives reel 8 rotations; One end of traction element 5 is fixed and is wrapped on the axis of traction 4, and the other end of traction element 5 links to each other with spring 6 one ends, and the other end of spring 6 is fixed.
In the present embodiment, said axis of traction 4 and 8 coaxial linking to each other of reel, it is stifled 9 also to be provided with reel on reel 8 outside inwalls, and reel stifled 9 places on the outer wall of axis of traction 4 simultaneously, is plugged in the reel 8 with axis of traction 4.
Said reel 8 peripheries also are provided with yarn box 1; The periphery of axis of traction 4, traction element 5 and spring 6 also is provided with slideway 2; The purpose of slideway 2 is the spaces that walk up and down when spring 6 stretches with traction element 5 in order to be provided for, and yarn box 1 can play dustproof effect attractive in appearance with slideway 2.
Said slideway 2 upper inner are provided with perforate, and also are provided with annular boss in the side towards reel 8, on the annular boss inwall, are provided with bearing 10, and bearing 10 is positioned at the outside of reel stifled 9, and places simultaneously on axis of traction 4 outer walls.
The inwall in said slideway 2 outsides is provided with groove, and on the groove inwall, is provided with bearing 10, and bearing 10 places on the outer wall of axis of traction 4 simultaneously.
Said slideway 2 also is provided with groove near a side of window screening 3, and the both sides of the edge of window screening 3 place in the groove.
One end of said spring 6 links to each other with traction element 5, and the other end is referred to as fixed end, and this fixed end is fixed on slideway 2 walls.
Said traction element 5 is a rope.
The bottom of said window screening 3 also is provided with handle 7.
In the present embodiment, can also carry out transmission through gear between said axis of traction 4 and the reel 8, traction element 5 can also be wire or software ribbon, and the fixed end of said spring 6 can also be fixed on wall or the forms.
The course of work of this instance:
During use; Handle 7 through window screening 3 bottoms spurs window screening 3 downwards, and the reel 8 in the yarn box 1 rotates thereupon together, and drives reel stifled 9 rotation together in the reel 8 right side inwalls; Reel stifled 9 drives axis of traction 4 and rotates; Axis of traction 4 is rolled rope 5 simultaneously, and rope 5 extension springs 6 make spring 6 produce pulling force.When opening window screening 3, because the pulling force that spring 6 produces makes rope 5 drive axis of traction 4 and rotates, axis of traction 4 drives reels stifled 9 and rotates, and reel stifled 9 drives reels 8 and rotates, thus window screening 3 backrush in the reel 8 of 1 li in yarn box.
The utility model has changed the dependence of screen window tradition automatic rewinding and has been contained in the defective that the spring torsion in the window screening reel is realized; A kind of method that relies on springs power to realize the screen window backrush has been proposed; This utility model has advantages such as simple in structure, easy to assembly, long service life.
