Description

The aluminium alloys screen window

The utility model relates to a kind of door, window or similar closure of special purposes, particularly a kind of aluminium alloys screen window.

Door and window on the building is enlarging the use alumium alloy door and window at present, and these door and windows mostly adopt retractable structure, and practical and attractive in appearance, price and wooden structure in the past are very nearly the same, are subjected to people's welcome.But because how the generation of these door and windows prevents in the mosquitos and flies inlet chamber that the applicant provides a kind of auto-closing screen window before this, it is to adopt the window screening cloth that drives by spring shaft on fixed support to realize this purpose.But this mode also has some deficiency, as inconvenient operation, and complex structure, the problem that cost is high, the utility model has designed a kind of aluminium alloys screen window again for overcoming the problems referred to above, makes it to have easy to operate, characteristic of simple structure is applicable to the use of alumium alloy door and window.

The purpose of this utility model provides a kind of mechanical type auto-closing aluminium alloys screen window.

The utility model is to adopt such method to realize: this device is to adopt the aluminium alloys angle section as bracing frame, on the both sides up and down of bracing frame angle section a fixed bearing is housed respectively, fixed bearing adopts the up and down two ends of screw at angle section, on fixed bearing, has a slideway, one slide block is housed in slideway, one end of slide block is in slideway, the other end interlocks then bottom end cover and upper end cover, two end cap connects a circle tube up and down, in the circle tube, on the upper end cover force transmission shaft is housed, one end of force transmission shaft is fixed in the top shoe by upper end cover, on the other end of force transmission shaft, has an opening, by opening part fixing spring part, the two ends of spring are fixed in the upper end cover.Slide block in slideway is fixed by the ball jump ring screw on fixed bearing.Be wound with window screening cloth on the circle tube, an end of window screening cloth is fixed on the cylinder, and the other end of window screening cloth is equipped with on the square tube.

Window screening is rolled onto on the reel, and by square tube pulling curtain, make the spring pretension curtain form automatically and unclamp and can tighten up this moment on reel.

During use, aluminium alloys angle type frame is fixed on the aluminum window, reel pull-off spring fixed point from the slideway, draws back window screening by square tube, draw back window thereupon, window screening also draws back thereupon, after window screening draws back reel is pushed in the slideway and by the jump ring fixed point and fixes.Window screening is close on window.When closing window, also the window screening reel is pulled out fixed point in slideway, unclamp square tube, window screening promptly is back on the reel.

The time spent is not decontroled square tube, unloads inferior horn type bracing frame.

The utility model compared with the prior art, have simple in structure, characteristics easy to use.And practical and attractive in appearance, be a kind of aluminium alloys screen window that can ventilate again in the mosquitos and flies inlet chamber of can preventing.

Concrete structure of the present utility model and embodiment are provided by the following drawings.

What accompanying drawing 1 provided is general structure schematic diagram of the present utility model.

Below in conjunction with accompanying drawing concrete structure of the present utility model and embodiment are done with further instruction.

See shown in the accompanying drawing: this device is to adopt the aluminium alloys angle section as bracing frame 1, on the both sides up and down of bracing frame angle section 1 fixed bearing 2 is housed respectively, 12, fixed bearing adopts the up and down two ends of screw at angle section, on fixed bearing, has a slideway, one slide block 5 is housed in slideway, 10, slide block 5, an end of 10 is in slideway, the other end is connecting upper end cover 4 and bottom end cover 11, be connected a reel 15 on the two end cap 4 and 10 up and down, a force transmission shaft 9 is housed on the upper end cover 4 in reel 15, one end of force transmission shaft 9 is fixed in the top shoe 5 by upper end cover 4, on the other end of force transmission shaft 9, has an opening, by opening part fixing spring 3 parts, the two ends of spring 3 are fixed on the upper end cover 4. Slide block 5,10 in slideway is fixed by screw 8 by ball 6 jump rings 7 on fixed bearing 2,12.Be wound with window screening 13 on reel 15, an end of window screening is fixed on the reel 15, and the other end of window screening 13 is equipped with on the square tube 14.

Window screening 13 is rolled onto on the reel 15, and by square tube 14 pulling curtain 13, make spring 3 pretensions curtain 13 form automatically and unclamp and can tighten up this moment on reel 15.

During use, aluminium alloys angle type frame is fixed on the aluminum window, reel 15 pull-off spring 7 fixed points from the slideway, draw back window screening 13 by square tube 14, draw back window, window screening 13 also draws back thereupon thereupon, after window screening 13 draws back reel 15 is pushed in the slideway and by the jump ring fixed point and fixes.Window screening 13 is close on window.When closing window, also window screening reel 15 is pulled out fixed point in slideway, unclamp square tube 14, window screening 13 promptly is back on the reel 15.
