Concealed hinge after the installation of the opening and closing of the problem, can be analyzed from its own structure and related installation structure to solve the problem:
Hinge own structure problems
Hinge arm problem: the hinge arm is responsible for connecting the hinge cup with the base fixed on the cabinet. If the length and angle of the hinge arm do not match the installation environment, it will make the hinge force uneven. According to the size and thickness of the door and cabinet, choose the right length and angle of the hinge arm. At the same time, the material and strength of the hinge arm is also very important, poor material, low strength of the hinge arm is easy to deformation, affecting the opening and closing, you should choose high strength metal hinge arm. You can choose SDH’s 3D adjustable hidden hinge, not only invisible after closing the door, but also using high-quality 3# zinc alloy or stainless steel and other materials made of high strength and good quality.
Installation structure
Door and cabinet problems: installation, if the door or cabinet plate is not flat, will make the hinge installation can not work properly. Before installation, you need to check the flatness of the plate and deal with the unevenness. In addition, the gap between the door plate and the cabinet is too small, will produce friction hindering the opening and closing, according to the requirements of the hinge installation, reserve the right gap.
Mounting hole problem: the size and positional accuracy of the mounting hole is very critical. Inaccurate hole position will make the hinge can not be installed correctly, resulting in poor opening and closing. Use professional hole cutting tools and positioning templates to ensure that the location of the mounting holes is accurate. If the mounting holes are too large or too small, the hinges will not be fixed securely or installed too tightly, according to the hinge specifications, need to drill the appropriate size of the mounting holes.
Connecting screws: If the screws connecting the hinge with the door plate and cabinet are not tightened or tightened too much, it will affect the normal work of the hinge.
Obstacles: In the hinge opening and closing, if there are other parts or sundry obstacles, will make the hinge can not open and close smoothly. After installation, check whether there are obstacles around the hinge, clean up in time.
