Common classification of hinges

Hinge, also known as hinge, is a mechanical device used to connect two solids and allow relative rotation between them. Hinges may consist of movable components or of foldable material. Hinges are mainly installed on doors and windows, while hinges are more installed on cabinets. They are mainly divided into stainless steel hinges and iron hinges according to material classification; In order to give people a better enjoyment, hydraulic hinges (also called damping hinges) have emerged, which are characterized by the buffer function when the cabinet door is closed, minimizing the noise generated by the collision between the cabinet door and the cabinet when it is closed.

Hinges occupy an important position in furniture hardware fittings. The quality of hinges is directly related to the use of furniture and doors.

Common classifications

1、According to the type of base, it can be divided into detachable type and fixed type;

2、 According to the type of arm body, it can be divided into two types: sliding type and card type;

3、According to the covering position of the door panel, it can be divided into a full cover (straight bend, straight arm) with a general cover of 18 cm, a half cover (middle bend, curved arm) with a cover of 9 cm, and a concealed door panel (big bend, big bend) with all doors hidden inside;

4、 According to the style of hinge development stage, it can be divided into: one section force hinge, two section force hinge, hydraulic buffer hinge, touch self opening hinge, etc;

5、 According to the opening angle of the hinge: generally 95-110 degrees, special ones include 25 degrees, 30 degrees, 45 degrees, 135 degrees, 165 degrees, 180 degrees, etc; [1]

6、 According to the type of hinge, it can be divided into: ordinary one and two section force hinge, short arm hinge, 26 cup micro hinge, marble hinge, aluminum frame door hinge, special angle hinge, glass hinge, rebound hinge, American hinge, damping hinge, thick door hinge, etc.

Classified by the place of use

1、General hinges

It is the general hinge that we often speak of. It can be used for cabinet doors, windows, doors, etc. The hinge can be divided into iron, copper and stainless steel in terms of material. The specifications can be divided into: 2 "(50mm), 2.5" (65mm), 3 "(75mm), 4" (100mm), 5 "(125mm), 6" (150mm), 50-65mm hinges for cabinets, wardrobe doors, 75mm hinges for windows, screen doors, 100-150mm hinges for wooden doors in doors, and aluminum alloy doors. The disadvantage of ordinary hinges is that they do not have the function of spring hinges. After installing the hinges, they must be equipped with various touch beads, otherwise the wind will blow the door panel. In addition, there are special hinges such as release hinges, flag hinges, and H hinges, which can be disassembled and installed according to various special needs. They are very convenient. They are divided into left type and right type due to direction restrictions.

2、Spring hinge

It is mainly used for cabinet doors and wardrobe doors. It generally requires a plate thickness of 18-20mm. From the material, it can be divided into: galvanized iron, zinc alloy. In terms of performance, it can be divided into two types: drilling required and drilling unnecessary. No holes are needed, which is what we call bridge hinge. The bridge hinge looks like a bridge, so it is commonly known as bridge hinge. It is characterized by no need to drill holes in the door panel and is not limited by the style. Specifications: small, medium, large. Need to make a hole, it is the spring hinge commonly used on the cabinet door. Its characteristics: the door panel must be perforated, the door style is limited by hinges, the door will not be blown open after being closed, and there is no need to install various spiders. Specifications:&26,&35. There are detachable directional hinges and non detachable non directional hinges. For example, the 303 series of Longsheng hinge is a detachable directional hinge, while the 204 series is a non detachable spring hinge. From the shape, it can be divided into: the hinge inside the full cover (or called straight arm, straight bending) half cover (or called curved arm, middle bending) (or called big bending, big bending) is equipped with adjusting screws. The height and thickness of the board can be adjusted from top to bottom, left to right. The distance between the two screw fixing holes on the side of the hole is generally 32mm, and the distance between the diameter edge and both sides of the board is 4mm (drawing). In addition, there are various special specifications for spring hinges, such as 45 degree hinge on the inside, 135 degree hinge on the outside, and 175 degree hinge on the opening.

The difference between three kinds of hinges: right angle (straight arm), half bend (half bend) and big bend (big bend):

The right angle hinge can make the door completely cover the side panel;

The semi curved hinge allows the door panel to cover some side panels;

The large bending hinge can make the door panel parallel to the side panel;

It is also divided into ordinary type and bearing type. The ordinary type has been mentioned above, and now we will focus on bearing type. The bearing type can be divided into copper and stainless steel in terms of material. In terms of specifications, 100X75 125X75 150X90 100X100 125X100 150X100 has a thickness of 2.5mm, 3mm bearing has two bearings and four bearings. From the perspective of consumption, there are many copper bearing hinges, which are beautiful, bright, affordable and equipped with screws.

4、 Hinge of electromechanical cabinet

It includes nylon hinge with high wear resistance; Corrosion resistant, high strength zinc alloy hinges and hinges; Stainless steel hinges with corrosion resistance, oxidation resistance and high strength are often used in mechanical and electrical cabinet doors, mechanical equipment operation boxes and other products

5、 Heavy hinge

Due to the particularity of the installation position, the requirements for hinges are also great. Generally, the size is more than 150mm, the bearing capacity is large, and the appearance structure conforms to the special structure of the cabinet door. It is commonly used for large doors such as refrigerators and freezers, and most of them are made of zinc alloy

6、 Special hinge

It is also a corner hinge with a large door opening angle, which is also widely used in daily use

7、Other hinges

There are table hinge, swing door hinge and glass hinge. The glass hinge is used to install the frameless glass cabinet door, and the glass thickness is required to be no more than 5-6mm. The pattern has holes and has all the functions of spring hinges. The non drilling type is magnetic suction type and upper and lower top mounted type, such as PepsiCo, magnetic glass hinge, etc.
