Description

Technical Field

[0001] This utility model relates to a four-dimensional adjustable hinge fixing base for a door leaf, which belongs to the category of hinge accessories and hardware products. Background Technology

[0002] Typically, hinges require three-way adjustment when installed on the door leaf and frame. Current technology uses a three-dimensional adjustment box installed within the door frame cavity, but this is only designed for surface-mounted hinges. For concealed swing-arm hinges, three-dimensional adjustment is difficult to achieve due to their installation within the door frame cavity. Manufacturing errors in doors and windows necessitate adjusting the gaps and dimensional accuracy between the frame and leaf through hinge installation and adjustment. Especially with the door consumer base trending younger and favoring minimalist, understated luxury styles, surface-mounted hinges can appear obtrusive and detract from the door's aesthetics. Therefore, there is a need to develop a door leaf mounting structure suitable for concealed swing-arm hinges, capable of three-dimensional adjustment and simultaneously adjusting the door leaf opening angle—a current market necessity. Summary of the Invention

[0003] Based on the above-mentioned product defects and requirements, the technical problem to be solved by this utility model is to provide a door leaf fixing seat structure that can be installed on the door leaf to realize four-dimensional adjustment of the swivel arm hinge or hinge, increase the opening angle of the swivel arm hinge, and is easy to install and adjust.

[0004] The following is the technical solution adopted by this utility model:

[0005] A four-dimensional adjustable hinge mounting base for a door leaf comprises at least a mounting base panel, an adjusting mounting plate, a screw hole plate A, a screw hole plate B, a guide bushing, an adjusting screw, screw A, screw B, a fixing bracket, a connecting shaft, a connecting piece, and a plane bearing. The adjusting mounting plate is symmetrically designed with threaded holes A matching the adjusting screw, guide holes matching the outer circle of the guide bushing, and several square mounting holes in the middle. At least one side of each square mounting hole has a grid-like or dot-like friction surface; this friction surface design enhances the mounting base's load-bearing capacity. The adjusting screw and the guide bushing are respectively mounted to the adjusting mounting plate. The outer circle of the hexagonal handle hole end of the adjusting screw is movably connected to the positioning hole A of the mounting base panel, and the outer circle of the other end of the adjusting screw is movably connected to the positioning hole B of the screw hole plate A. Screw A passes through the fixing shaft hole A of the fixed seat panel and the connecting hole of the guide bushing, and is connected through the threaded hole B of the screw hole plate A to form the basic frame of the fixed seat. The square mounting hole allows for adjustment of the front-to-back and vertical positions of the door leaf and door frame. The adjusting screw, adjusted by a hexagonal handle, allows for adjustment of the left-to-right gap between the door leaf and door frame, achieving three-dimensional adjustment of the door leaf and door frame. Screw B passes through the fixing hole B of the mounting foot plate of the fixed bracket, the square mounting hole of the adjusting fixed plate, and the threaded hole C of the screw hole plate B, fixing the mounting foot plate of the fixed bracket to the adjusting fixed plate. The connector has a fixing part, a connecting part, and a connecting section. The fixing part of the connector has a shaft hole B, which connects to the connecting part shaft hole A of the fixed bracket via a connecting shaft to form a four-dimensional adjusting hinge fixed seat.
