Abstract
The utility model relates to an automatic winding window screen comprising a coiled spring and window screen, an external shell and a reel. The utility model is characterized in that both ends of the reel are respectively provided with a rolling support column and the hollow cylinder of the support column. The coiled spring is an axial coiled spring which is arranged in the reel and whose both ends are respectively fixed on the spiral thread unit of the rolling support column and the spiral thread unit of the fixing seat of the coiled spring. The automatic winding window screen is provided with guiding tracks which are respectively fixed on the window frames at the left and the right both sides and a window screening fixer fixed under the guiding track. The lower end of the window screen is provided with a pull rod whose both ends are respectively connected with latch bolts.
Description
The utility model is about screen window device, particularly about the automatic curtain screen window.
The spring type screen window that currently marketed a kind of two is fixing, its primary structure comprises wind spring, window screening, shell, spool etc.Because unreasonable structure exists many drawbacks: 1. do not have guide rail, cause gauze bending when opening and closing, it is undesired to use; 2. wind spring two is fixed, and unadjustable degree of tightness can produce transverse bending during use, out-of-flatness occurs; 3. when screen window is closed, owing to the window screening bottom center is fixed, so unbalance stress, more impel the out-of-flatness of window screening.
The purpose of this utility model be to provide a kind of can regulating spring degree of tightness, make when reeling and the even tension fixedly the time, thereby make window screening smooth, well-pressed, install, easy to use, the automatic curtain screen window.
The purpose of this utility model is achieved in that a kind of automatic curtain screen window that comprises wind spring, window screening, shell, spool, it is characterized in that: described spool is the hollow cylinder that two ends are respectively arranged with rolling bearing post and bearing post; Axial wind spring on the threaded body that described wind spring is arranged in the above-mentioned spool, its two ends are separately fixed at rolling bearing post and wind spring holder; Be provided with guide rail that is separately fixed on the window frame of the left and right sides and the fixer of window gauze that is fixed on above-mentioned guide rail below; The lower end of window screening is provided with the pull bar that two ends are connected with dead bolt respectively.
The utility model will be further described below in conjunction with accompanying drawing.
Surface structure schematic diagram when Fig. 1 is to use.
Fig. 2 is the schematic perspective view of the utility model structure.
Fig. 3 is the structural representation of spool and wind spring.
Outward appearance of the present utility model as shown in Figure 1, it includes bracket 1 and 30, shell 4, guide rail 20 and 29, fixer of window gauze 17 and 26, window screening 10, pull bar 14 and shakes hands 13.Bracket 1 and 30 is fixed on the left and right sides, window frame top, shell 4 is installed between bracket 1 and 30. Guide rail 20 and 29 is separately fixed on the window frame of the left and right sides.Fixer of window gauze 17 and 26 is separately fixed at the below of guide rail 20 and 29.The below of pull bar 14 is provided with hairbrush 15.The top of window screening 10 is fixed on the spool 8(Fig. 2 that is arranged in the shell 4) on.Spool 8 is hollow circular cylinders, and its two ends are respectively arranged with rolling bearing post 23 and bearing post 7.Bearing post 7 has the axle 2(Fig. 3 that stretches out).Axle 2 is bearing in the axis hole of the end plate 6 that is positioned on the bracket 30.The end that rolling bearing seat 23 is positioned at spool 8 is provided with threaded body and the other end is provided with protruding pin, the center is a through hole.Rolling bearing seat 23 embeds in the heavy groove of spline stalk of spool 8 one ends with the spline of one end.Change the relative position of splines and spline by rotation rolling bearing seat 23, can regulating shaft to the elastic force of wind spring.Rectangle axis hole, its other end that axle 18 flat ends that pass rolling bearing seat 23 are bearing in the end plate 3 that is positioned on the bracket 1 are fixed with the wind spring holder 25 that an end is provided with threaded body with bearing pin 24.Axially the two ends of wind spring 21 are separately fixed on the threaded body of rolling bearing seat 23 and wind spring supporting base 25.The both sides of window screening 10 are provided with a series of protruding button 9 by certain distance respectively.Protruding button 9 is arranged in guide rail 20 and 29 when window screening 10 moves downward.Pull bar 14 is connected with the bottom of window screening 10, and its two ends are respectively arranged with dead bolt 16 and 27.Guide rail 19 and 29 is respectively arranged with connector 19 and 28, can guarantee width error appropriate installation in+30 millimeters of window.Be respectively arranged with movable snap close 22 in the fixer of window gauze 17 and 26.Shell 4 is provided with weather strip 5.
The utility model is owing to the elastic force of axial wind spring not only can be adjusted with mode of occupation, and the axial deformation of axial wind spring is not had an effect to window screening during work, add the restriction of the guide rail of both sides, make window screening four sides when closing evenly stressed, so window screening is smooth indeformable.In addition,, can stop mosquitos and flies effectively, be particularly suitable for the rural area and use if use through scribbling the window screening of medicament against mosquitoes specially treated.Component of the present utility model adopt aluminium alloys or stainless steel and engineering plastics manufacturing, not only elegant in appearance, non-corrosive, and can make that window screening opens and closes flexibly, noise is low.
