adjustable door hinge

Abstract

An adjustable door hinge comprises a left containing base and a right containing base in pairs and a set of arch arm assemblies, wherein the left containing base and the right containing base can be buried in a door leaf or a door frame, and the arch arm assemblies can form variable bending angles. The left containing base and the right containing base are respectively provided with a pair of fixing parts capable of adjusting displacement, and the two ends of the arch arm assemblies are connected to the pair of fixing parts in the left containing base and the pair of fixing parts in the right containing base respectively. The adjustable door hinge is characterized in that one fixing part of the pair of fixing parts in the left containing base or the pair of fixing parts in the right containing base comprises a straight arm sunk into one of the containing bases, and straight teeth are arranged on the straight arm; the corresponding containing base is provided with a gear corresponds to the straight teeth, the gear is located on the side edges of the straight teeth and meshed with the straight teeth, and when rotated, the gear can drive the fixing parts to move. The adjustable door hinge can be applied as an adjustable concealed door hinge used in daily life because having the characteristics and advantages.

Description

technical field [0001] The invention relates to a door hinge which can be embedded in a door leaf or a door frame, in particular to an adjustable door hinge. Background technique [0002] The patent number is 200910212200.2, and the application date is November 13, 2009. The invention patent named "Hidden Door Hinge" discloses a door hinge for concealed installation between the door frame and the door panel. The edge of the door panel and the first and second leaf assemblies in the mortise in the door frame, and corresponding mounting protrusions that are movable relative to the body of the leaf assembly. The door hinge also includes an at least two-part swivel mechanism supported on an insert in the leaf assembly. In order to enable the displacement of the mounting protrusions to be adjusted relative to the main body of the second leaf assembly in the Z-axis direction, a mechanical adjuster is installed in each protrusion of the second leaf assembly, and the mechanical adj...

AI Technical Summary

Problems solved by technology

However, there is still a problem that cannot be ignored in the adjusters of the Z-axis and Y-axis of the above-mentioned door hinge. The two adjusters can only adjust the protrusion in one direction. If the displacement of the protrusion is too large, it will not meet the requirements. When adjusting the adjuster in the opposite direction, the displacement of the protrusion cannot be reduced. At this time, the protrusion can only be directly operated by hand or other tools, and it is very difficult to directly adjust the protrusion.

For this reason, the above-mentioned adjuster only has one-way adjustability, which makes the adjustment operation of the door hinge very cumbersome, and when the door leaf is used for a long time, the adjustment mechanism will loosen, thereby losing the original adjustment effect. The stability of the above adjustment mechanism is not ideal
