Good doors and windows are inseparable from high-quality hardware. On the contrary, low-quality hardware accessories will not only greatly reduce the user experience, but also affect the life of doors and windows. Therefore, it is not surprising that the hardware of doors and windows is called the "heart" of doors and windows.
So what do the hardware of the door and window contain? The "five" in the door and window hardware is an imaginary word is not a quantifier. It is a general term for all kinds of metal and non-metal parts installed on the doors and windows of buildings. They play an auxiliary role when the doors and windows are opened and closed. .
1. Hinge, hinge, sliding support
Hinge hinges and hinges are the core components that support the opening and closing of doors and windows. The performance of doors and windows is closely related to the selection and assembly of hinges, hinges, sliding supports. It is worth mentioning that we have to take into account their range of gravity when choosing. Choose the appropriate installation according to the weight and size of the doors and windows. For example, heavy-duty doors and windows use light hinges, hinges, and sliding brackets to cause the doors and windows to tilt.
Second, the transmission rod, transmission box
The transmission rod and transmission box are important accessories for opening and closing of doors and windows. They are also used frequently and subject to major wear and tear, so we have to choose materials with good durability and corrosion resistance. In terms of performance, it is also necessary to consider its anti-mite ability and its stability performance installed on the door and window.
Third, the lock seat, lock point
The lock point and the lock seat can play the role of closing and fixing the door and window, and are the main accessories for ensuring good security of the door and window. Nowadays, there are two kinds of lock points and single lock points available on the market for consumers to choose. Simply put, each lock point is like a bolt. A multi-lock point is equivalent to more than 2 bolts. A single lock point is equivalent to a bolt. Therefore, multiple lock points are much stronger than single lock points, and the price is also more expensive. . In addition, it depends on the material of the lock seat and the lock point. The thief with poor material quality will be broken twice, and its anti-theft ability will be weak.
Fourth, handle
Door and window handles are divided into three categories: multi-point lock handle, single-point lock handle, and linkage handle.
The multi-point lock handle is the most common and widely used handle system. By changing the position of the handle of the handle, various opening functions are realized, the operation is convenient, the impact is simple, and the lock body itself has an encryption function, which is difficult to emulate and has high safety performance.
The single-point lock handle realizes the function of opening and closing the window and locking the function by rotating the handle. It is relatively simple in terms of structure and function. The opening and closing and locking of the window can be realized by turning the handle, and the device such as the transmission rod (transmission lock) is not required to cooperate with the installation. Can be straightforward to understand as a rotating pin.
The linkage handle is composed of two upper and lower switch locking devices, a link type linkage mechanism and a handle connected with the lower locking device. It can be locked when the plastic casement sash is opened or closed. It mainly solves the problem that the upper and lower seals are badly sealed by a single handle switch sash, and the operation is inconvenient with two single handles.
