Applications of hinges in various industries

Related applications of hinges

A hinge device, often simply called a “hinge”, is a mechanical device used primarily to connect two solid objects and allow limited rotational movement between them. In daily life, hinges are used everywhere, and the most common form is door hinges, which enable doors to be opened and closed.

The basic structure of a hinge usually consists of two metal sheets connected by a central pin. Depending on the application, the material, size, and design of the hinge can vary greatly. For example, hinges on household doors may be simple steel hinges, whereas for applications requiring corrosion resistance, such as marine or exterior doors and windows, the hinges may be made of stainless steel or other more corrosion-resistant materials.

The design of the hinge needs to take into account not only load-bearing and frequency of use, but also aesthetics and safety. Some hinges are designed to prevent hand pinching, or can automatically close doors and windows to improve convenience and safety during use. In addition, with the development of technology, some high-end hinges also integrate intelligent technology, such as hinges in smart home systems that can sense switch status. This type of hinge can be connected to the home automation system to achieve remote control and status monitoring, improving the sense of technology and convenience of use.
