Description

Dual purpose latch for door and window

The utility model relates to a kind of five metals thumb-latch, is a kind of Dual-purpose door window latch.

At present, the latch that uses on the door and window, major part is made up of fixed head, inserted link and baffle plate three parts, function singleness, fixed head is complex-shaped, complex production process, the big materials of volume are many, the cost height.

The purpose of this utility model is a kind of Dual-purpose door window latch of design, both can make latch and use, and can play fixedly right angle effect again, both can be simplified to fix the plate shape, reduces operation, but reduced volume again, and weight reduction reduces cost, convenient use.

The purpose of this utility model is achieved in that this latch is by baffle plate, fixed head with turn round sheet and form, fixed head is rectangular in shape, and 3-5 wood screw hole arranged above, and the back-shaped curved open slot that makes progress is arranged in the right angle outside, turn round sheet and be fixed on the stile of fixed head, can swing around axle by axle is movable.During use, be fixed on the sash angle with wood screw about will fixed head dividing, baffle plate will be fixed on the corresponding position of window frame by wood screw, when turning round sheet and change baffle plate groove over to, can sell extremely, and produce and to window.

This utility model is compared with existing latch and had the following advantages: (1) function is many, both can make latch and use, and can replace fixedly right angle again; (2) the little materials of volume are few in light weight; (3) simple shape, cost of production is low; (4) to reverse, easy to use for sliding up and down.

Be described further below in conjunction with accompanying drawing:
