Description
The utility model relates to a kind of automatic window fastener of amounting to.
No. 30 EO5C17/14 of existing patent gazette 7 volumes, notification number: CN2081414U, title: Windproof window hook, by hook, stay hook seat, hook base and reverse the Windproof window hook that bullet Huang etc. constitutes a kind of manual switch.But people still insert hook with hand when windowing, and it is convenient inadequately to use, and forget hook after windowing sometimes and make the drawback of smashing the window glass to strong wind.
The purpose of this utility model is to provide a kind of sash is slightly firmly pushed open, and window fastener just supports the steady automatic window fastener of amounting to sash automatically.
Technical solution of the present utility model is such, amounts to automatic window fastener and uses leg-of-mutton fastness and tetragonal changeability principle and design, and is made up of engaging lug, tension spring, support bar cover, support bar.Engaging lug and support bar are applied mechanically the axle nail and are connected and rivet tightly, and the axle nail is inserted in tension spring, tightens up the crooked end of tension spring by banking pin, and support bar injects in the support bar cover, and rivet tightly with spool following closely.
Operating principle of the present utility model is: because window fastener is to adopt the convertible design apparatus, so when closing window, it is a folded position, when windowing, it is straight and upright state.When opening window, because sash to inner rotary, is just drawn back window fastener by folded position, when sash rotated to certain position, window fastener just was drawn as straightened condition.Because three moving points are on same straight line on the window fastener, under tension spring and spacing effect, thereby support bar cover and support bar are endured delicately automatically outward very much, window fastener can not be amounted to, make sash continue again to change outward, also can not close inward, played the steady effect of sash support.In the time will closing window, slightly toward pulling back, tension spring has broken away from spacing with the anti-straight and upright direction of handgrip window fastener, and the support bar cover is amounted to as the pocket knife that turns back with sheet shape support bar, makes sash go back to the position of closing window along with amounting to of window fastener.
The utlity model has simple in structurely, implement easily, easy to use, it is promptly steady to push away window, has overcome the downer of hanging window catch.Good stability has prevented to blow the drawback that strong wind is smashed the window glass.
Further specify the utility model below in conjunction with accompanying drawing.
