What is a hinge door stopper (what is a door top, door stop, floor stop, hemispherical door stop)

What is a door top? A door top is a device used to support a door. It typically consists of a bottom plate with an L-shaped cross-section and a slot plate with a slot hole. The slot plate is installed on the outside of the long arm of the bottom plate and is fixedly connected with a ball device at its lower end. The long arm of the bottom plate is equipped with a screw and nut for installing the slot plate. When installed at the bottom of a door, the door top prevents the door from deflecting and deforming.

A door stopper, also known as a door touch, is a device used to absorb and position the door leaf after it is opened. Its purpose is to prevent the door from being closed by the wind or touching the door leaf. There are two types of door stoppers: permanent magnetic door stoppers and electromagnetic door stoppers. Permanent magnetic door stoppers are manually controlled and commonly used in ordinary doors. On the other hand, electromagnetic door stoppers are used in electronically controlled door and window equipment, such as fire doors. They have both manual and automatic control functions.

A floor stopper is a metal product installed on the ground to hold the door in place, similar to a door top. It prevents the door from closing completely and can be used as an alternative to a door top.

A hemispherical door stop is a specific type of door stopper. It is shaped like a hemisphere and is installed on the floor to stop the door from closing.

In addition to door tops and stoppers, there are various other types of door and window hardware. Some commonly used examples include handles, braces, hinges, door closers, latches, window hooks, anti-theft chains, and induction opening and closing door devices.

Handles provide a means of opening and closing doors and windows. They come in different shapes and materials, such as metal, wood, or plastic.

Braces are used to strengthen doors and windows, providing stability and preventing warping or sagging.

Hinges are essential hardware for doors and windows. They allow for smooth movement and rotation, enabling doors and windows to open and close properly.

Door closers ensure that the door closes accurately and quickly after being opened. They are hydraulic devices that automatically close or hold the door at a certain position. Different types of door closers include floor springs, door top springs, door slingshots, and magnetic door suction heads.

Window hooks are used to secure windows in specific positions, allowing for ventilation while keeping them securely in place.

Anti-theft chains provide an additional layer of security by limiting the opening range of doors and windows.

Induction opening and closing door devices use sensors to automatically open or close doors, providing convenience and accessibility.

All these hardware accessories serve the purpose of enhancing the functionality of doors and windows, making them more convenient and user-friendly.
