Hinge is an important product of gating hardware, look be like very small, often can cause big trouble.Hinges as a important product of the doors and Windows hardware industry, application of almost throughout the world, as long as there is door window where you can see his shadow.So these problems in the process of application and purchase, you notice?
1. The hinge of choose and buy local requirements.Different requirements for different areas of the hinge, such as inland and coastal, basin and plain.The hinge of choose and buy must consider when regional characteristic.Coastal waters, the sea breeze salinity, corrosion resistant ability of hinge is a severe challenge.Hinges made of different materials, different surface treatment of the hinge of corrosion resistance is not the same.So choose hinge in addition to consider hinge the uniformity of color matching with the color of the door also consider its corrosion resistance, adjust measures to local conditions, must consider the regional characteristics.
2. Pay attention to the hinge rotation is smooth.It is well known that the hinge is in use process, once installed on the door, is along with the door back and forth, once the rotational irregularities will affect the use effect.Have stuck, the phenomenon such as sound, affect the use.Qualified hinge rotation smooth, flat, smooth, reaming force falling slowly, slowly to fall.
3. The hinge of the oscillation amplitude.Hinge problem of transverse oscillation amplitude is also worth attention.Especially heavy configuration of door hinge, more attention should be paid to the problem.We know hinge center has a core shaft, shaft core is through the hinge trunnion, hinge volume circle diameter and axial diameter matching degree is particularly important, it directly affects the degree of horizontal swing hinges.Once loaded on the door, use for a period of time, this phenomenon is more obvious.Seriously affect the door closed, door close does not reach the designated position, often need to lift to reach the designated position, in the bearing on the door is more apparent, bearing a relatively thick, hinge mount door hinge has a force, force by hinge roll round to axis core, the tilt to the side door there is a certain degree.So, choose the door hinge clearance and it is important to note that hinge axis transverse oscillation problem.
4. The problem of hole and screw.Usually hole location does not significantly affect the use, unless it is pre-installed door when drilling in advance, so will, consider hinge hole it fits the pre-drilled, otherwise you will be unable to pack.Also need to consider the thickness of the door, hinge generally with screws, that’s right, but with screw, match and your door thickness?Once don’t match, can appear screw through the door.So you need to pay attention to this problem.
5. Turn around.Hinges in use process must absorb a certain amount of weight from the door, in the process of bearing, flat head will also force, gravity in the rotation process to door hinge itself peace head, flat head and crimping loose contact once appear, will appear fall off turning phenomenon.So hinges of choose and buy must pay attention to turn around, special design can make the hinge to avoid the emergence of the problem, such as the hinge flat rub flower processing, thus increasing the flat and roll round of contact area, the greater the contact area, contact more fully, the risk of will not be turned back.
