The hardware of
aluminum alloy doors and windows is composed of: control part, lock part, load-bearing part, and help part. They complement each other and are indispensable. The most widely used non-ferrous metal structure material in the aluminum alloy profile industry is in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, construction, and decoration. The important hardware of sliding doors and windows are: pulleys, single-point locks, multi-point locks, and handles for communicating ideas. 1.1 Selection of pulleys The configuration and quality of sliding doors and windows directly affect the wind pressure resistance, air tightness and other physical functions of the doors and windows, as well as the insurance and service life of the doors and windows. Because of the different materials and structural design, the pulleys have different load-bearing levels. The choice should be based on the size of the profile, the structure and the weight of the window sash. 1. The nominal data of the pulley wheels are: polycarbonate, nylon and metal (copper, aluminum, etc.). 2. There are two types of pulley bearings: bushing type and ball type. The bushing type manufacturing process is relatively simple, and the bearing is heavy, but the sliding is not very mobile. The ball type is mostly used on the door, the sliding motion is moving, the noise is small, and the bearing is heavy. 3. The sliding wheel is divided into single wheel and double wheel, and adjustable and non-adjustable. The adjustable wheel adjusts the overlap of the frame fan by adjusting the height of the wheel frame. The double wheels can actively adjust and balance, and the force is even. It is mostly used on heavy windows with doors and heels. 4. Carrying weight: the weight of a single wheel with better quality is 35kg, and the individual weight is about 20kg. The individual bearing weight of the double wheels is 50-80kg, preferably 100kg, and the bearing capacity is calculated by 2 pulleys. The selection of the pulley should be judged according to the weight of the door and window sash, the installation space of the
aluminum profile and the bearing weight of the pulley. The weight calculation of the door and window sash: (glass component + profile component) x insurance coefficient 1.3, the thicker the shaft core, the greater the absolute bearing weight, and the double wheel is better than the single wheel. 1.2 Selection of crescent locks, single-point locks and multi-point locks The important device of crescent locks is on the sashes (hooks) of sliding doors and windows. Crescent locks and locks should be selected according to the structure and width of the window sash hooks. Single-point lock: It is a strip lock, which is installed on the side seal of the sliding window. The strip lock and the lock seat are selected according to the structure and width of the side seal. The most widely used non-ferrous metal structure material in the aluminum alloy profile industry is in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, construction, and decoration. The multi-point lock device is installed on the side seal of the light enterprise, and the multi-point locker and the lock seat should be selected according to the structure and width of the side seal of the light enterprise. It can be equipped with a square-shaft handle and a box-type multi-point locker, or a fork-type handle and a nail-type multi-point lock.
