Description

Lock for windows

The utility model belongs to the improvement invention of lock for windows, is suitable for a kind of novel aluminum alloy push-pull window.

Existing lock for windows is various in style, but a kind of novel aluminum alloy push-pull windows of incompatibility all is restricted to show kind of the development of aluminum alloy push-pull window.The characteristics of this sliding sash are: medial surface has the three rib bar around the window frame, up and down as guide rail.And be convex.And the side is provided with groove around the window frame, establishes pulley in the lower recess.This kind pulley is a fixed mechanism, and supreme adjusting down can't be eliminated the gap of carrying on the window; When closing, window frame lateral grooves is inserted mutually with the rib of window frame medial surface.Because rib and groove side clearance are very little, existing lock for windows latch hook and fastener can't be installed.

The purpose of this utility model is to improve the fastener shape and a kind of above-mentioned novel lock for windows that pushes away window that is applicable to is provided.

The purpose of this utility model is finished by following technical scheme: comprise latch hook and fastener on lock housing, lock core, the lock core, lock core can vertically move on lock housing.Described fastener is divided into discount and Button Block two positions, and this discount is the sheet hook of vertically erectting, and this Button Block is positioned at the one-sided of discount and becomes 90 °～100 ° angles with discount.

The above-mentioned lock housing and the structure of lock core are various, have manually, automatic etc., can be provided with spring, steel ball, insurance institution therebetween, or the like.

Above-mentioned discount can be the sheet hook of varied geometry, hook is changeable, can be wide can be thick, and can on discount, offer anti-carry recess or convex clip, correspondence is set up defences and is carried convex clip or recess on lock housing again, perhaps discount, latch hook extend, and hook length is equal to or greater than phase hook length and adds window and window tank bracket gap sum up and down.

Fastener of the present utility model becomes unidirectional 90 °～100 ° angles because of discount with Button Block, so can be installed in the lateral groove of window frame, discount is near section bar rib sidewall, and discount is the sheet hook of vertically erectting, and realized that hook and button interlock to hook (accompanying drawing 5,6).

Offer anti-recess and the anti-convex clip of carrying carried at discount, perhaps discount, latch hook lengthening then can prevent to carry on the window, and lock core moves down to break off relations and windows, and has anti-theft effect.
