Blown when blowing hard for the sash that makes unlatching is unlikely and to be pulled window catch or the window button causes damage, now occurred multiple adjustable sash positioner.Chinese patent CN87210933U has announced a kind of " window automatic locking positioning device ", its main feature is to have vertical hollow runner on backstay, one has anti-raise one's hat and the location pin of holder is inserted in the hollow runner, under certain longitudinal force effect, can in chute, realize many grades of lock-bits of sash, its weak point be on the arm of chute both sides, be provided with some to making positioning pin column be stuck in therebetween dislocation stop block or contraposition groove, the longitudinal force that requires backstay to slide is bigger, otherwise stuck phenomenon can take place, can not regulate the sash opening angle.

The purpose of this utility model is at above-mentioned not enough a kind of improved self-locking window button that proposes.

The purpose of this utility model is achieved by the following technical programs.It by an end be riveted on sash fixedly ear positioning pipe and be riveted on window frame fixedly the alignment pin of ear form, the upper surface of positioning pipe equidistantly is placed with at least two locating holes, relative lower surface has set vertical breach.Positioning pipe can be a square tube, also can be pipe.Alignment pin can insert the locating hole of positioning pipe by top ends and the bottom is passed vertical breach of positioning pipe and is riveted on the fixedly bearing pin on the ear of window frame, be enclosed within the stage clip of bearing pin periphery, and place the upper and lower pad at the stage clip two ends of the upper and lower end face of positioning pipe inboard to form respectively.Upper and lower pad is fixing stage clip both, can transmit the stage clip active force again bearing pin is locked at locating hole, and positioning pipe is held on the alignment pin.

When regulating the sash opening angle, make the bearing pin top ends of alignment pin deviate from locating hole as long as upwards mention positioning pipe with the extruding stage clip, promote positioning pipe then, the bearing pin top ends will be inserted next locating hole under the stage clip effect, and make lock clasp at this locating hole by lower gasket, even positioning pipe is held on the alignment pin, rock to prevent sash, avoid causing damage.Window frame fixedly ear is made steppedly, adjusts the fixedly relative position of ear of itself and sash, can make the bearing pin top ends insert positioning pipe press close to sash fixedly during the locating hole of ear end sash close and be close to window frame.

The utility model is simple in structure, and firm position is cheap, and operation is light and handy, safe ready.By the disposable action of windowing, just can make sash be opened to required angle, and be self-locking in locating hole securely.It is applicable to timber window, the steel sash of various types and specification, is particularly useful for not having the window of the public place that the special messenger keeps an eye on, to substitute old-fashioned window catch and latch.
