In the process of installing doors and windows, we need to use hinges, which are a kind of hardware used to connect. The mother-in-law hinge is a hinge hardware for installation on the interior door. When designing the hinge, two hinges of different sizes are used, which look like a pair of mother and child, and a mother-child door. The reason is basically similar. The main body hinge body includes a hinge piece and a hinge shaft, and is usually made of stainless steel, iron, or copper. So what is the specification of the parent-child hinge? What are the advantages and disadvantages of the parent-child hinge? Let's take a look at it!
First, the advantages and disadvantages of the mother and child hinge
In terms of durability, the flat hinge is better than the parent hinge because the length of the parent hinge is the same as the length of the ordinary hinge, but the inner and outer sheets of the parent hinge are overlapped. The effect is that the inner page is reduced, and the outer piece is hollowed out. From this point of view, the durability is certainly not comparable to the flat hinge with two complete pages, and the hinge rotation and bearing weight are often Depending on the middle ring, the degree of wear resistance of the middle ring and the degree of closure of the middle axis directly determine the bearing capacity of the hinge. The hinges are usually four central rings, and the mothers are two. From this point, it is also the mother. The durability of the hinge is higher than that of the flat hinge.
From the convenience of use and the adaptability to the door, the parent-child hinge undoubtedly has the absolute advantage. The biggest selling point of the mother-in-law hinge is that it is easy to use, because it is relatively flat and hinged, without slotting. It directly reduces the damage to the door, greatly enhances the beauty of the door. More importantly, some non-solid wood doors (composites) or hollow wooden doors can not withstand the slotting, and barely open the slot to open the hinge. After a period of time, there may be serious quality problems such as door leaf shedding, door leaf perforation, etc., and the unique design of the factor mother hinge is not directly installed in the slot, which enhances the integrity of the door and greatly enhances the hinge for various types. The applicability of the inner door.
Advantages of child and child hinges:
1. Easy to use and flexible.
2, the installation is simple, no need to slot, it will not damage the beauty of the door. Especially suitable for some doors that cannot withstand slotting.
3. The application range is wider.
Sub-mother hinge disadvantages:
1, not durable, easy to break, often need to be replaced.
2, bearing small.

Third, how to buy the child hinge
The advantage of the parent-child hinge is that the two pieces of the hinge are thinner than the ordinary hinge. Generally speaking, the heavier wooden door is not suitable for the hinge of the mother and child, because it is easy to deform the door to droop, as long as the hinge is not deformed, the joint of the shaft is tightly closed and normal, so be careful not to choose too thin.
The core of the hinge is that the bearings, smoothness, comfort and durability are all determined by the bearings.
The bearing of the inferior proton hinge is made of iron sheet, which is not durable, easy to rust and lack of friction, so that the switch door will make a "squeaky" sound for a long time. The high-quality hinge bearing is made of stainless steel and is equipped with all-steel precision balls. The real ball bearings, bearing and feel have reached international standards. It guarantees the flexibility and smoothness of opening the door, mainly silent.
The high-quality hinges are made of 304 stainless steel and have a thickness of 3 mm. The color is uniform and the processing is exquisite. It can obviously feel heavy and thick in the hand, and the hinge is flexible and flipped. There is no “stagnation†phenomenon, the hand feel is fine, and the corners have no cutting edge.
