Description

A kind of lock for sliding door and window

The utility model relates to a kind of lock for sliding door and window.

Chinese patent ZL94210933.3 utility model discloses a kind of automatic window catch.It is made up of holder and fasteners, and its primary structure is the movable hook that sways under the torque spring effect, and movable hook is bearing in by axle in the dead slot of holder, and this structure can combine the action of windowing and unblanking, and finishes with same active force.But this structure exists in actual production installs difficulty, the shortcoming that production efficiency is low.Mainly be because axle will pass 6 axis holes on holder, torque spring and the movable hook respectively.Will overcome the bounce raise positive position of torque spring on one side with hand during installation, Yi Bian wear axle, accidentally, will be stabbed wound finger by spring, speed of production is slow.Moreover this structure exists spring fatiguability ageing failure in actual use, and the axle oxidation and rusting makes movable hook rotate difficulty, even rust extremely can not rotate.

The purpose of this utility model be design in order to overcome above-mentioned shortcoming a kind of simple in structure, assembling easily, the lock for sliding door and window of safety durable.This sash lock in use can make " opening " or " pass " window only just finish with an action equally.

The utility model is achieved in that a kind of lock for sliding door and window, handgrip and latch hook fuse, and handgrip stretches in the lock body frame, and the latch hook front end has gib head to match with stay hook, be provided with back-moving spring between latch hook two ends and the lock body frame, base plate is covered with latch hook and is fixedly mounted on the lock body frame.

Handgrip of the present utility model and latch hook fuse, with lock body frame and base plate interface point is fulcrum, and handle is scratched with fulcrum when the active force plate of being windowed is moving, makes the gib head of latch hook break away from stay hook, it is compression spring that back-moving spring changes torque spring, is arranged between latch hook two ends and the lock body frame.The utility model has been saved rotating shaft, has used spring instead, have simple in structure, assembling easily, the advantage of safety durable.

Further specify the utility model below in conjunction with accompanying drawing:
