Description

Technical Field

[0001] This utility model relates to a door leaf fixing base structure, belonging 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 for concealed swing-arm hinges that allows for three-dimensional adjustment, a current market necessity. Summary of the Invention

[0003] Based on the aforementioned 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 three-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 door leaf fixing base structure includes at least a door leaf panel assembly, a two-dimensional adjustment fixing base, a connecting fixing shaft, and a planar support. The door leaf panel assembly includes a door leaf hinge plate and a positioning device. The two-dimensional adjustment fixing base includes at least a fixing component, a pressure plate, pressure plate screws, and adjusting screws. The fixing hole A of the fixing part of the two-dimensional adjustment fixing base is connected to the shaft hole B of the door leaf hinge plate via the connecting fixing shaft. The connecting fixing shaft and the fixing hole A are fixedly connected by a rivet or a set screw. The connecting fixing shaft and the shaft hole B of the door leaf hinge plate are rotatably connected and their rotation is limited by the positioning device or by a certain angle of rotation. When rotation is restricted, the hinge hole B of the door leaf hinge plate will not rotate relative to the connecting fixed shaft when no external force is applied to the fixing component. This allows the hinge arm to rotate around the arm's rotation axis. When the hinge arm rotates to its limit around the arm's rotation axis, the door leaf assembly overcomes the locking force of the positioning device under the action of external force, increasing the opening angle of the door leaf hinge plate. Alternatively, the door leaf hinge plate can first rotate around the connecting fixed shaft by a certain angle, and then the rotation of the door leaf hinge plate around the connecting fixed shaft is restricted, causing the hinge arm to rotate around its own rotation axis, increasing the hinge opening angle. The connecting fixed shaft is provided with a locking groove or a positioning groove or positioning hole around the positioning device to restrict the rotation of the door leaf hinge plate.

[0006] Furthermore: the door leaf panel assembly includes at least a door leaf hinge plate and a positioning device. The positioning device includes a positioning device structure or a spring clip structure consisting of an external threaded device body, a spring, and a steel ball. The outer side of the shaft hole B of the door leaf hinge plate is provided with a threaded hole that is perpendicular to and intersects the center line of the shaft hole B. The threaded hole penetrates the wall of the shaft hole B. The positioning device is installed on the outer side in cooperation with the threaded hole. The mounting base plate of the door leaf hinge plate is provided with at least a number of longitudinal or transverse conical oval mounting holes A and circular holes. An eccentric shaft is provided on the circular hole, and the front and rear positions of the door leaf relative to the door frame can be adjusted by the eccentric shaft.

[0007] Furthermore: the fixing component of the two-dimensional adjusting fixing seat includes a fixing part shaft hole A, a connecting part, and a connecting plate between the connecting part and the fixing part shaft hole A; the connecting part is provided with a rectangular mounting hole B, a pressure plate screw hole A, and an adjusting screw hole B; the rectangular mounting hole B vertically penetrates the connecting plate and is used to accommodate the connecting part of the connecting hinge arm; the pressure plate screw hole A and the adjusting screw hole B are respectively used to install the pressure plate screw and the adjusting screw.

[0008] Furthermore, the planar support component can be a planar bearing structure consisting of a planar shim plus a T-shaped bushing, two planar shims with a copper washer sandwiched in between, a steel ball planar bearing, or a planar washer, etc. Preferably, the planar shim plus T-shaped bushing combination hinge has strong load-bearing capacity and long service life.

[0009] Furthermore, the hinge arm connecting part is provided with a square hole with a gap of 3-6mm between it and the pressure plate screw, and a mesh connecting surface. The gap between the square hole and the pressure plate screw allows for adjustment of the hinge's position in both left, right, up, and down directions, while the mesh connecting surface increases the connecting friction.

[0010] Furthermore: the pressure plate of the two-dimensional adjustment fixing seat is provided with mounting holes and pressure plate screws that pass through the mounting holes and connect with the pressure plate screw hole A. The pressure plate decorative cover plate is connected to the hexagonal hole of the pressure plate screw to decorate the surface of the pressure plate, making the hinge look simple, beautiful and pretty.

[0011] The application effects of this utility model are:

[0012] 1. This utility model has a simple and elegant appearance with a high aesthetic appeal, which better meets the design requirements of modern light luxury door panels.

[0013] 2. Easy to install and adjust, with strong load-bearing capacity, it allows for three-dimensional adjustment of the swivel arm concealed hinge or hinge.

[0014] 3. It allows the concealed hinge of the swivel arm to rotate around the connecting fixed axis through the door hinge plate, increasing the hinge opening angle. Attached Figure Description
