A hinge is a component made of movable material, sometimes made of foldable material. The use of hinges is characterized by the ability to connect two inflexible objects together, so that the two inflexible objects can rotate flexibly and relativly. This kind of mechanical device is used in many places, and there are many materials of hinges. There are also hinges of various materials developed in the traditional concept. The following editor will introduce the attention to the use of hinges, the classification of hinge structure, and the method of hinge selection.
Attention to the use of hinges
1.Wipe gently with a dry soft cloth, do not clean with chemical cleaners or acidic liquids. If you find black spots on the surface that are difficult to remove, wipe with a little kerosene.
It is normal to make a sound after using it for a long time. In order to ensure that the pulley is muted for a long time, everyRegular lubricating oil maintenance can be added for 2-3 months.
3.Heavy objects and sharp objects should be prevented from crashing and scratching.
4.Do not pull hard when handling, damage the hardware of the furniture connection.
Introduction to the classification of hinge structure
Hinges occupy an important position in furniture hardware fittings, and the quality of hinges is directly related to the use of furniture and doors.
Common classification
1According to the type of base, it is divided into two types: detachable type and fixed type.
2According to the type of arm body, it is divided into two types: sliding type and card type.
3According to the cover position of the door panel, it is divided into full cover (straight bend, straight arm) general cover 18%, half cover (middle bend, curved arm) cover 9%, and the inner (big bend, big curve) door panels are all hidden inside.
4According to the style of hinge development stage, it can be divided into one-stage force hinge, two-stage force hinge, hydraulic buffer hinge, touch self-opening hinge, etc.
According to the opening angle of the hingeCommonly used 95-110 degrees, special 25 degrees, 30 degrees, 45 degrees, 135 degrees, 165 degrees, 180 degrees, etc.
6、According to the type of hinge, it can be divided into:Ordinary one-and two-stage force hinges, short arm hinges, 26 cup micro hinges, billiard hinges, aluminum frame door hinges, special angle hinges, glass hinges, rebound hinges, American hinges, damping hinges, thick door hinges, etc.
Classified by place of use
1.General hinge
It is what we often call general hinges, which can be used for cabinet doors, windows, doors and so on. Hinge, from the material can be divided intoIron, copper, stainless steel. From the specifications can be divided into: 2 "(50mm), 2.5" (65mm), 3 "(75mm), 4 (100mm), 5" (125mm), 6 "(150mm), 50-65mm hinges suitable for cabinets, wardrobe doors, 75mm for windows, screen doors, 100-150mm for wooden doors, aluminum alloy doors. The disadvantage of the ordinary hinge is that it does not have the function of spring hinges, and all kinds of beads must be installed after installing the hinges, otherwise the wind will blow the door. In addition, there are release hinges, flag hinges, H hinges and other special hinges they can be disassembled and installed according to a variety of special needs of wooden doors, very convenient, limited by the direction of use, divided into left type and right type.
2.Spring hinge
Mainly used for cabinet doors, wardrobe doors, it generally requires a plate thickness of18-20mm. From the material, it can be divided into: galvanized iron, zinc alloy. In terms of performance, it can be divided into two types: need to make holes, do not need to make holes. There is no need to drill a hole is what we call a bridge hinge. Bridge hinge looks like a bridge, so it is commonly known as bridge hinge. It is characterized in that it does not need to drill holes in the door panel and is not restricted by style. The specifications are: small, medium and large. Need to make a hole, is now commonly used in the cabinet door spring hinge and so on. Its features: the door panel must be holed, the style of the door is limited by hinges, the door will not be blown open by the wind after it is closed, and there is no need to install all kinds of spiders. The specifications are: & 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 that can be divided from shape: full cover (or straight arm, straight bend) half cover (or curved arm, middle bend) inner side (or big bend, big bend) hinge with adjusting screws, which can adjust the height and thickness of the plate up and down, left and right, and the distance between the two screws on the side of the hole is generally 32mm. The distance between the diameter edge and the two sides of the board is 4mm (drawing). In addition, the spring hinge has a variety of special specifications, such as: inner 45-degree angle hinge, outer 135-degree angle hinge open 175-degree angle hinge.
About right anglesThe difference between three kinds of hinges: (straight arm), half-curved (half-curved), and big-curved (big curved):
The right-angled hinges allow the door to completely block the side panel
The half-curved hinge allows the door panel to cover part of the side panel.;
The hinges of the big bend make the door panel parallel to the side panel.;
3.Gate hinge
It is divided into ordinary type and bearing type, the ordinary type has been mentioned above, and now focuses on the bearing type. The bearing type can be divided into copper and stainless steel in terms of material and specification.: 100X75125X75 150X90 100X100 125X100 150X100 thickness has 2.5mm, 3mm bearings have two bearings, four bearings. From the point of view of consumption, there are more copper bearing hinges because of its beautiful style, bright style, moderate price and screws.
4.Electromechanical cabinet hinge
It includes nylon hinges with high wear resistance.Corrosion-resistant, high-strength zinc alloy hinges, hinges; corrosion-resistant, oxidation-resistant, high-strength stainless steel hinges, often used in electromechanical cabinet doors, mechanical equipment operation boxes and other products
5.Heavy hinge
Due to the particularity of the installation position, the requirement for the hinge is also very large, the general size is inMore than 150MM, large load-bearing capacity, shape and structure in line with the special structure of cabinet doors, often used for cold storage, freezers and other large doors, mostly made of zinc alloy
6.Special-shaped hinge
It is also a corner hinge with a large opening angle and is also relatively extensive in daily use
7.other hinge
There are table hinges, flip door hinges, and glass hinges. Glass hinges are used to install frameless glass cabinet doors, and the glass thickness is required to be no greater than5-6mm。The style has holes and has all the properties of spring hinges. Non-hole holes are magnetic suction type and top-mounted type, such as Pepsi, magnetic glass hinges, etc.
Selection method of hinges
Look at the material and weigh the weight
The hinge is of poor quality, and the cabinet door will easily fall back and forth after being used for a long time, loosening and sagging. Almost all cabinet hardware parts of big brands use cold rolled steel and are stamped and formed in one go, has a thick feel and a smooth surface. Moreover, because the surface coating is thick, it is not easy to rust, is strong and durable, and has strong load-bearing capacity. The inferior hinge is generally made of thin iron sheet welded and has almost no resilience. If it is used for a long time, it will lose elasticity, resulting in the cabinet door. The door is not closed tightly or even cracked.
Experience the feeling
Hinges with different advantages and disadvantages feel different when used. Hinges with excellent quality have a softer force when opening the cabinet door.It rebounds automatically at 15 degrees. The resilience is very uniform. Consumers can open and close the cabinet doors more often when purchasing to experience the feel.
View details
Details can show whether the product is excellent, thereby confirming whether the quality is outstanding. The hardware used in high-quality wardrobe hardware has a thick feel and a smooth surface, and even achieves a silent effect in design. Poor quality hardware is generally made of cheap metal such as thin iron sheet, and the cabinet door is stretched uneasily and even has a harsh sound.
In addition to visual inspection and feel that the hinge surface is smooth and smooth when selecting a hinge, attention should be paid to the return performance of the hinge spring. The quality of the reed also determines the opening angle of the door panel. A good quality reed can make the opening angle exceed90 degrees,
tips
Hinge can be openedAt 95 degrees, press hard on both sides of the hinge with your hand to observe that the supporting shrapnel is not deformed or broken. It is a very strong product of qualified quality. Poor quality hinges have a short service life and are easy to fall off. For example, cabinet doors and hanging cabinets fall off, mostly due to poor quality of the hinges.
The editor above introduced everyone to how to purchase hinges, what categories of hinges are, the structural characteristics of hinges, and what you need to pay attention to when using hinges. The place where hinges are used more in everyone's daily life is in the kitchen. There are many cabinets in the kitchen. Most cabinet doors are connected by hinges, and then the cabinet doors can move relatively. There are many classifications of hinge structures. Everyone should make it clear when buying and don't buy the wrong hinge.
