1. Window opener
The window opener is mainly used to open high position ventilation windows. The window opening actuator can determine the width of the window opening, and its deformation determines the ability of the window opener to adapt to different window types and installation conditions. The operating components can be in the form of handles or rockers. There is also a manual window opener, which is only suitable for hanging in and hanging out windows.
2. Door closer
The main feature of the door closer is its slow closing speed and no collision sound after closing. It is mainly used for doors in high-end hotels. The door closer can be divided into horizontal type and straight type. It acts as a double spring hinge and can automatically close doors and windows after opening.
3. Hinge
The hinge should choose a bearing with a ball bearing in the center axis. The brightness of the paint and electroplating during selection determines the flexibility and noise of the drawer opening and closing. Therefore, a wear-resistant and evenly rotating load-bearing wheel should be selected.
4. Handle
The shapes of the handle are quite diverse, and its main materials include aluminum, copper, stainless steel, etc. By electroplating the handle, it has wear-resistant and anti-corrosion effects. When selecting it, in addition to matching the decoration style of the room, it should also be able to withstand a large tensile force, providing a protective effect and keeping the home in a safe state.
5. Pin
The bolt is actually a simple component that prevents opening, and is a anti-theft component that prevents doors and windows from being opened from the outside. The structure is much simpler than a lock, except that it is locked outside the door and the bolt is inside the door.
