The application of the hinge in the door leaf is very extensive, and it is an indispensable accessory. We generally seldom notice it, but it plays a great role in the door leaf, providing a buffer function for the door leaf when it is closed, reducing noise. and friction.

Today, the corner editor of the hinge manufacturer will give you a very important piece of hardware - the hinge, and the knowledge of the hinge under the in-depth science.

What are the functions of hinges?

The main function of the hinge is to suspend the door leaf support to realize the free rotation of the door leaf. Some special types of hinges realize some additional special functions, such as wire-through hinges, self-closing hinges, etc.

What are the main performance indicators of the hinge?

The very main performance index of the hinge is the load-bearing performance, and the load-bearing performance index is generally 10Kg as a grade unit. Other performance indicators of hinges include service life, corrosion resistance, etc. According to different standard systems and test methods, there are different indicators. For example, in the European standard, there are requirements for the amount of deformation after the life test; and there are stricter requirements for resistance to elastic deformation and plastic deformation.

What are the influences of the use environment on the hinge?

Different use environments have different requirements for hinges. For example, in large public buildings, doors are used very frequently, and generally the size of doors is relatively large, so hinges with high load-bearing performance and long service life need to be selected. Another example is the application of the seaside or the storage of a certain series of chemicals, there are higher requirements for the corrosion resistance of the hinge, and it is necessary to choose a hinge with a special material or anti-corrosion surface treatment.
