The front end of a swing rod is connected with the slide box, and the rear end is connected with a supporting seat which is fixed to the lower rafter of the window frame. When wind and rain come, the window sash can be automatically closed under the direct action of wind force or the elastic force action of the energy storing spring whether the wind blows the outer face or the inner face of the window sash. So the blowing disorder and the drenching of furniture are prevented from temporary gusty wind and the rain when no body is at home.

Description

Automatic window-closing window catch

The utility model is relevant with the sash that is used for closing any opening, door leaf or similar component.

The sash of general closing any opening is manually controlled, if nobody home has been opened at the fan family, storm arrives suddenly, and family property is drenched by wind and rain and blows unrest in the family.

The utility model provides a kind of wind and rain to close sash fastener automatically to the public.

The utility model is by Slide Box 1, energy-stored spring 2, and bearing 3, swing arm 4 is formed.Chute 5 front ends pass Slide Box 1, chute 5 be fixed on that the fixed hinge on the rafter 6 flexibly connects under the sash, there is energy-stored spring 2 rear end.Fixed hinge 6 is under sash on the rafter.Swing arm 4 front ends and Slide Box 1 usefulness rivet flexibly connect; Its rear end and bearing 3 usefulness screws flexibly connect.Bearing 3 is fixed under the window frame on the rafter.

The utility model has the advantages that the interim window that closes automatically rapidly of wind and rain, both protected the glass on the sash, prevent that again family property from exempting to be drenched by wind and rain.

Details of the present utility model elaborates from drawings and Examples.

Embodiment Slide Box 1 is the box of square or cuboid, and shell 7 is divided into two-layer up and down by partition 9.Opening slot 8 on the partition 9, grows up in 10 millimeters in the hole, and the hole is wide 2 millimeters.Card 10 is on partition 7, and an end passes oblong aperture 8, inserts the cotter way 23 of chute 5, and it is tubular that the other end curves the garden, and Screw 11 passes on the aperture that pipe is fixed on Slide Box two walls.Control wheel 12 by before, during and after three wheel sheets form.Middle wheel sheet 14 is opened three grooves, and the front is a groove, and the back is two grooves, and the screw thread little spring is arranged in the groove, and there is little pressure tongue 16 the spring outer end, and front-wheel sheet 17 inner faces have a groove and middle wheel sheet 14 to coincide.Trailing wheel sheet 18 inner faces are opened two grooves, coincide with middle wheel sheet 14.After three wheel sheets were superimposed, outer rim respectively had 19, three small embossments of individual small embossment point-blank.It is an integral body that wheel sheet 13 links with Screw again.Central authorities open the hole, and axis of rotation 20 passes from through hole.The Slide Box two side is passed at axis of rotation 20 two ends, and an end is fixed with nut, a termination turn-knob.There is arc switch 21 partition 9 tops, and arc switch ends is also passed Slide Box 1 front and back two walls.The two sides of Slide Box lower floor are removed.Chute 5 is " Jiong " shape, and chute 5 has horizontal draw-in groove 23, and front end flexibly connects with the fixed hinge 6 that is fixed on rafter under the sash, and the rear end is connected with energy-stored spring 2.Energy-stored spring 2 has spring housing 25, and it is fixed on rafter under the sash.Slide Box 1 bottom flexibly connects with rivet and swing arm 4.

Swing arm 4 is " Jiong " shape, and front end and Slide Box 1 bottom flexibly connect, and rear end and bearing 3 usefulness screws flexibly connect.Swing arm 4 rear end leading flanks leave long 1 centimeter " Jiong " shape groove 26.Pendulum controller 27 in the dress in swing arm 4 " Jiong " groove.Interior pendulum controller 27 has orientating box 28, screw thread spring 29, washer 30 and fixed bar 31.Orientating box 28 no cappings, front-back is longer than two sides, and the back is shorter than the front slightly.There is trip(ping) lever 32 in the upper right corner, front.Orientating box 28 left and right sides face central openings, fixed bar 31 passes from the hole, and fixed bar 31 penetrates thread-shaped spring 29.Washer 30 is to curve the right angle with iron plate, and a right-angle side is screwed on swing arm 4, and another right-angle side is holded up.The right-angle side central authorities of holding up open 1 hole, and fixed bar 31 passes from the hole.

Bearing 3 has rectangular bottom 33, half garden ratchets 34 and screw 35, bottom stage casing projection, and a hole is respectively opened at two ends, is screwed on window frame the lug boss central openings.Half garden of half ratchet partly is a ratchet, and another part is a rectangle, is converted into the right angle under rectangle two opposite side, tightly is stuck on the bottom 33.The diameter central openings of half ratchet.Screw 34 passes half ratchet 34 and swing arm 4 rear end hinges from bottom projection central authorities.

The course of work of the present utility model is: the established angle of sash and window frame is 80 °.Window by manually carrying out.When wind-force closed window, wind-force acted on the sash outside sometimes, claimed with the wind, and wind-force acts on the sash inner face and is called against the wind sometimes.Close the window part with the wind and be work like this: before any rotation limit of sash is, with the window frame hinge limit be after.Sash is inwardly closed under the wind-force effect, and Slide Box 1, drives swing arm 4 simultaneously and inwardly rotates, thereby window closed is closed to front slide along chute, and chute and swing arm are superimposed.When sash bore against the wind, swing arm 4 strained at the chute 5 that is connected with sash, because the function of the outside unidirectional slip of the draw-in groove 23 on card 9 and the chute 5, Slide Box can only be to front slide, can not make reverse slide, energy-stored spring 2 is compressed, and wind direction becomes slightly, energy-stored spring releases energy, there is component to promote Slide Box 1 advance lattice or number lattice, meanwhile drives the inwardly certain angle of swing of swing arm 4, after several fitful winds, sash closes and has closed, and chute 5 is superimposed with swing arm 4.
