Description

Window catch

Technical field

The utility model relates to a kind of window catch.

Background technology

Window catch kind is more, starts angle difference can be divided into full angle window catch and Partial angle window catch by sash, and the hook arm of full angle window catch is exactly often a pole, pole is shorter, cause when sash is opened by window catch is fixing, window axle is stressed excessive, and window axle tabs easily damages.

Summary of the invention

Object in utility model is to provide the collapsible firm supporting of a kind of hook arm and the non-damageable window catch of window axle.

For realizing this reality and novel object, the technical solution of the utility model is such, a kind of window catch, by hook arm and bearing that hook arm two ends are fixed on jamb and door frame, formed, be characterised in that altogether: two poles of hook arm are connected by removable pin, the other end of two poles respectively be fixed on jamb bearing and be connected by removable pin with the bearing being fixed on door frame, on pole, have a groove, another pole end correspondence position is provided with limiting card, and limiting card engages with groove.

The utility model has the advantages that 1, firm supporting, when groove engages with limiting card, can stand impact more energetically, 2, can make window axle not fragile, because hook arm is comprised of two poles, long in same angle unlatching situation when two poles are linked to be straight line, bearing is contained in from axle distant positions more, window axle is stressed less, not fragile.
