In terms of durability, the ordinary 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 have to be overlapped. In this way, 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 ordinary hinge with two complete pages, and the rotation and load bearing of the hinge are often determined by the middle. 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 common hinges are usually 4 middle rings, and the mothers are two. From this point, it is also the durability of the mother and child hinges. The reason for the difference between the ordinary hinges.
From the convenience of use and the adaptability of 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 easy to install with ordinary hinges, without directly It reduces the damage to the door and greatly enhances the beauty of the door. More importantly, some non-solid wood doors (composites) or hollow wooden doors can not withstand the slotting, barely slotting the ordinary hinges, after a period of time. After the time, there may be serious quality problems such as door leaf falling off, 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 of interiors. The applicability of the door.
