Window Door Handles Are Classified By Function
When we see a window for the first time, we often notice two things: the window frame and the window and door handle. There is actually a lot of knowledge about the handle, so I will briefly talk to you.
The handle is a device that is installed on the door and window sash and has the functions of opening and closing. It is used to control the switches of doors and windows. For example, it is the steering wheel and remote control of doors and windows.
Most handles are made of aluminum alloy, copper, stainless steel, plexiglass, plastic, and other materials. Different shapes and sizes can be made. In addition to having the necessary grip and satisfying the corresponding physical properties, it also has decorative effects. Therefore, the materials and shapes are selected from finished products or designed separately according to architectural design requirements.
Generally speaking, in terms of function, we usually divide door and window handles into three categories: multi-point lock handles, spinning handles (also called seven-character handles), and external casement window linkage handles.
Among them, the multi-point lock handle is the most common and widely used category. It is defined as a drive transmission lock, a multi-point lock, and a control device that realizes the opening and closing of doors and windows. on the hanging window.
The seven-character handle is the most common name for the spinning handle because it looks like the number "7" from the side. Its official definition is a device that can open and close a window and lock it by turning the handle. Compared with other handles, its structure and function are relatively simple, and the window can be opened, closed, and locked easily by turning the handle, and there is no need for devices such as transmission rods (transmission locks) to cooperate with Ancheng work. . The spinning handle can also be regarded as a rotating latch. It is a more economical option. The scope of use is casement windows and top-hung windows with a diagonal of no more than 700mm.
As we know from the name of the external casement window linkage handle (handle), the use of this handle is limited to the external casement window, so the probability of daily use is relatively small.
