Abstract

The utility model relates to a double-roller opposite rolling type mesh window, which is composed of a secondary winding bobbin, a primary winding bobbin, a window screen, a sealing strip, a window frame, the housing of a primary winding bobbin, the housing of a secondary winding bobbin, a sealing stopper, a roller wheel, a guide groove, a gear, and a rack. The window screen is coiled around the secondary winding bobbin and the primary winding bobbin, and the axle necks at both ends of the secondary winding bobbin are respectively provided with a spiral spring. The utility model has the advantages of convenient operation, staying at optional position, preventing the phenomenon of flies mosquitos and winged insects coming indoors, and the window screen is always tensioned in the switching process with a peripheral sealing, so the utility model is an ideal screen window for the modern family.

Description

Two-tube to the rolling screen window

The utility model relates to a kind of room window technology field, especially screen window.

At present, the employed screen door and window of esidential building or office is flat opening, and it is bigger to take up space during unlatching, after the yarn breakage, changes inconvenience.Now people extensively develop the push-and-pull screen window of automatic curtain, though open conveniently, do not take up space, and window screening can not be tightened all the time, and periphery do not have weather strip, and mosquitos and flies easily pierces.

The purpose of this utility model is exactly at above-mentioned weak point, designs a kind of two-tubely to the rolling screen window, and this window window screening in switching process is tightened all the time, and the periphery sealing.

The purpose of this utility model is achieved through the following technical solutions:

Form the utility model by auxiliary yarn rolling tube, main yarn rolling tube, window screening, weather strip, window frame, main yarn rolling tube outer cover, auxiliary yarn rolling tube outer cover, sealing block, roller, gathering sill, gear, tooth bar etc.Respectively establishing wind spring, an auxiliary yarn rolling tube on the two ends axle journal of auxiliary yarn rolling tube is positioned on the wind spring shell, gear is located on the upper and lower axle journal of main yarn rolling tube, also be provided with plane bearing under the main yarn rolling tube on the axle journal, upper and lower tooth bar is embedded respectively on the sidewall channels of upper and lower gathering sill, main yarn rolling tube links to each other with roller by lower shaft neck supporting member, and the window screening two ends are located at respectively on main yarn rolling tube and the auxiliary yarn rolling tube.The upper and lower weather strip of screen window is embedded respectively on upper and lower gathering sill upper side connector.Window frame is located at the side that screen window is closed, and the side seal bar is embedded on window frame, also is provided with the circular arc sealing block on window frame.

Use principle of the present utility model is such: when holding the main yarn rolling tube outer cover and closing window, the upper and lower axle journal supporting member that connects firmly with shroud moves thereupon, be contained in the effect of main yarn rolling tube by upper and lower wheel and rack on the upper and lower axle journal supporting member this moment, not only move but also rotate, realize putting the yarn action.In putting the yarn process, when the yarn tube diameter on the main yarn rolling tube during less than the pitch circle diameter, main yarn rolling tube whenever circles puts the displacement that yarn length whenever turns around less than gear, at this moment, under the tension of window screening, auxiliary yarn rolling tube rotates, and emits window screening, the curtailment when the compensation main yarn rolling tube is put yarn.In the screen window opening process, master file yarn volume moves round about and rotates, and realizes the volume yarn.When gear diameter during greater than yarn tube diameter, the volume yarn length that the displacement that gear whenever circles then whenever turns around greater than the master file screen window, at this moment, auxiliary yarn rolling tube is under the twisting force of upper and lower wind spring, loose window screening is rolled, made window screening remain certain tensity.In volume yarn process, when yarn tube increasing diameter to greater than the pitch circle diameter time, promptly the volume yarn length that whenever turns around of main yarn rolling tube whenever turn around greater than gear displacement the time, the window screening on the auxiliary yarn rolling tube is drawn out the curtailment when replenishing main yarn rolling tube volume yarn again.In addition, because the effect of weather strip, sealing block, fly, mosquito, winged insect are difficult for piercing indoor.

Technical characterstic of the present utility model and result of use:

1, novel structure, simple and practical is extremely easy to use, as long as gently draw the main yarn rolling tube outer cover just can realize closing or opening of screen window, and can stop at an arbitrary position, and screen window remains certain rate of tension.

2, screen door structure is tight, and it is indoor to prevent that mosquitos and flies and winged insect from piercing.

3, major and minor volume spool outer cover, window frame, gathering sill is profile structure up and down, and is elegant in appearance, cost is low, is easy to a large amount of productions.

4, the assembling of tooth bar, weather strip all adopt embedded, thereby make things convenient for installation, maintenance and change.
