Characteristics and classification of hinge

According to the structural characteristics, hinges can generally be divided into open hinges and concealed hinges; According to material classification, it can be divided into zinc alloy hinge, stainless steel hinge, plastic hinge and iron hinge; It can be divided into ordinary hinge and damping hinge according to its functional characteristics. No matter by structure, material or function, there are overlaps among various classifications. The structure, material and function of hinge are summarized below, and the hinge is classified as follows. You can find the required hinge clearly.
Exposed hinge
The exposed hinge is also known as the exposed hinge. After the hinge body is installed, the hinge can be clearly seen. Generally, there are two morphological features:
One is a blade type with a pin in the middle, which is symmetrical/asymmetric from left to right; It is composed of blades with mounting holes/without mounting holes/without mounting holes and studs; The most typical open hinge is the hinge JL233 series.
Another typical open hinge is composed of several square hinge bodies, such as JL206 series.
Concealed hinge
The concealed hinge is also called concealed hinge. After the hinge body is installed, it is not easy to see the hinge. Generally, it has two morphological characteristics:
One is JL101 series;
Stainless steel hinge
If the requirements for corrosion resistance and strength of hinge are high, in addition to conventional zinc alloy hinge, stainless steel hinge can generally be selected. The common hinge is 304 stainless steel hinge. If the requirements are higher, 316 stainless steel hinge can be selected.
In addition to its high price, the stainless steel hinge has excellent performance in terms of beauty, corrosion resistance and strength.
Damping hinge
Generally, the hinge has no damping function when closing the cabinet door. The biggest feature of the damping hinge is that it has damping function. When the electric cabinet lock exerts a certain force on the cabinet door, the door will move and complete the locking operation.
Plastic hinge
The plastic hinge is also good at corrosion to acid and alkali. Compared with stainless steel hinge, the price is much lower. Generally, ABS plastic hinge is used for plastic hinge. However, the biggest disadvantage of plastic hinges is that they are not high in strength, not resistant to high temperature, easy to age over a long time or in long-term outdoor environment.
The above classification of hinges covers the characteristics of hinges comprehensively. The selection of hinges should be based on the specific use environment.
