How many types of common window handle?
Generally speaking from the functional point of view, we usually divide the window handle into two categories: multi-point window handle, spinning handle which also called it seven shape window handle, because it shape like the number "7".
Multi-point window handle
Multi-point window handle is the most commonly and widely used type handle. Its working principle is through the transmission rod (transmission lock) to cooperate with the window handle to finish the process of window open and close; Its application scenarios: home, office buildings, commercial building all of internal and external casement Windows, indoor sliding doors, and top-hung windows.
From the appearance of the structure, we can subdivide the multi-point window handle into: fork window handle; square shaft window handle; lever handle.
Fork window handle
As can be clearly seen from the shape above, there is a "U-shaped" fork at the bottom of the fork handle, which is where the name is derived. Its working principle: U-shaped fork stuck transmission rod or transmission device, through the rotation of the handle bar to control the U-shaped fork up and down translation to drive the operation of the transmission structure.
In the purchase and installation of the fork multi-point window handle should pay attention to the following points:
A, The handle and window frame profile should be matched each other
B, fork window handle is divided into left-side and right side handle.
C. Determine the exposed length of the fork
Of course, these problems need to be paid attention to, AOSITUO hardware sales staff will help you take into account, if you interested in our products, please provide your window frame profile diagram . However, if you have a specified type of handle, please know the length of the fork before consulting. Fork length can be customized according to your requirements.
Square shaft window handle
From the shape of the figure above, we can clearly see that, compared with the fork handle, the square shaft handle just replaces the U-shaped fork with the square shaft. Because of the square shaft, so named square shaft window handle. It works in much the same way as the fork multi-point window, spin the handle bar to match the transmission lock to complete the locking and opening process.
In the purchase and installation, we should pay attention to the following points:
A, the handle should be match to the window frame profile each other
B, the window handle is divided into left-side and right side.
C, determine the length of the square shaft and the cross section size of the square shaft.
D. Square shaft with lock and without lock.
Lever handle
From the shape of the picture above, we can clearly see that this is a double-sided handle. You can see why it's called that. Its working principle is basically the same as the square shaft window handle, on the basis of the original added double-sided open/close function, the lever handle is generally with a lock. The length of the square shaft can usually be customized as per customer’s need.
Spinning handle (handle)
The seven shape handle is the most common name for the spinning handle because it looks like the shape of number "7" when viewed from the side. Its official definition is: by turning the handle, the realization of window opening and closing, locking function of the device. Compared with other handles, its structure and function are relatively simple. By turning the handle, the window can be easily opened, closed and locked, and it does not need the transmission lever (transmission lock) and other devices to cooperate with the installation. spinning handle, a simple type handle, It is a more economical option for customers.
Above is the common types of window handle for simple introduction, at our everyday life, we will meet kinds of windows, so the corresponding window hardware accessories also has a lot of segmentation, the function and principle is also different, we need to know about them and convenient to our life!
