Crescent lock on the sliding windows details:
Crescent lock (window lock) is widely used in push-pull windows of plastic steel and aluminium alloy. The hardware for opening and closing sliding windows is the crescent lock. Because of its shape like the crescent moon, so insiders call it the crescent lock. The crescent lock not only plays the role of opening and closing, but also plays the role of anti-theft to a certain extent.
The appearance of crescent lock generally includes spray paint, baking paint, spraying, electroplating and so on. Most of them are white and aluminium. There are many different styles of crescent lock. The high-quality crescent lock is weighted in the hand; the appearance is smooth and there are no pits; the crescent lock can rotate 180 degrees (some can rotate 360 degrees). The high-quality crescent lock rotates more flexibly and freely, without noise and good elasticity; turning to the back, the good crescent lock is mostly spring structure. The Center material is galvanized material, which is not easy to rust; from the thickness of the material, it is relatively thick. The inferior crescent lock of the same size is lighter, smaller, dim and dull in appearance. It is not particularly flexible to open. It is easy to jam and loosen for a long time, which greatly weakens the performance of opening, closing and anti-theft. The style of crescent lock has long handle, short handle, inclined handle, etc.
Several important data of the crescent lock. One is the height (the height is the distance from the base to the crescent center about 5 millimeters to the highest point), and the other is the width (the distance from the center line of the screw to the crescent). Another is the distance between the center line of the screw and the edge of the base.
