Abstract
Description
Technical Field
[0001] This utility model relates to the field of hinge technology, and in particular to a three-dimensional adjustable hinge. Background Technology
[0002] Existing windows consist of frame materials, glass, and hinges, assembled into complete windows for sale and installation. During assembly, each part needs to be matched, but there are slight deviations in the production of each component. The frame and sash sizes are not always perfectly aligned. Furthermore, assembly typically involves installing the window frame and sash first, followed by the hinges. During assembly, mismatches frequently occur due to overlapping or improper assembly of the hinges. Hinges, as one of the main moving hinges of doors and windows, primarily support the opening and closing of the window sash and frame. However, existing hinges only provide stable support and lack adjustment capabilities, making it difficult to ensure a secure connection between the hinge and the frame, as well as a proper seal. This makes it difficult to resolve various problems that may arise when the window sash is opened and closed. Utility Model Content

The window frame connecting unit is connected to one end of a first link and a second link, and the other end of the first link is connected to one end of a third link. The other end of the second link is connected to a window sash connecting unit. The first link and the second link are configured with a central cross structure and the overlapping part is configured as a movable connection. The other end of the third link is connected to the window sash connecting unit. The window frame connecting unit and the window sash connecting unit are respectively connected to a window frame and a window sash. The window frame connecting unit is configured to be adjustable left and right, and the window sash connecting unit is configured to be adjustable up and down and front and back.
[0005] Preferably, the window frame connecting unit includes a window frame connecting piece vertically disposed at one end. The window frame connecting piece is provided with a first movable clip and is connected to a window frame connecting base plate at its bottom. Above the window frame connecting base plate, from one end of the window frame connecting piece, a copper washer, a left and right adjusting bolt, a movable clip fixing bolt, a slide rail, and a locking bolt are sequentially disposed. Below the window frame connecting base plate, from one end of the window frame connecting piece, a left and right adjusting piece, a second movable clip, a sliding bolt, and a locking rotating piece are sequentially disposed. The copper washer is disposed between the first connecting rod and the window frame connecting base plate. The left and right adjusting bolt is connected to the left and right adjusting piece at its bottom. The movable clip bolt is connected to the second movable clip. The sliding bolt is placed in the slide rail and is connected to the second connecting rod. The locking bolt is connected to the locking rotating piece through the window frame connecting base plate.
[0006] Preferably, the window sash connecting unit includes a mounting plate. The bottom of the mounting plate is connected to the window sash connecting base plate and one end of the second connecting rod respectively by upper and lower adjusting bolts. The third connecting rod is connected to the middle of the bottom of the window sash connecting base plate. The mounting plate has an adjusting hole on one side where the upper and lower adjusting bolts are located. A front and rear adjusting bolt is placed inside the adjusting hole. The front and rear adjusting bolts are connected to a window sash adjusting plate. A window sash fixing bolt is provided on the top of the window sash adjusting plate. A window sash fixing block is provided on the bottom of the window sash adjusting plate. The window sash fixing block is engaged with a window sash fixing hole, which is located on the window sash connecting base plate.
[0007] Therefore, the three-dimensional adjustable hinge of this invention, with the above-described structure, has the following advantages compared with the prior art:
[0008] 1. The hinge of this utility model can be adjusted up and down, left and right, and front and back to compensate for minor deviations during the installation of door and window frames (such as uneven walls or measurement errors), ensuring that the window sash and window frame fit perfectly. By adjusting the hinge depth, the window sash and sealing strip are pressed evenly to avoid local air leakage, water seepage or sound insulation failure.
[0009] 2. The adjustable hinge of this utility model can eliminate the problems of window sash friction, jamming or sagging, and solve common problems (such as not closing tightly or handle misalignment) without disassembling the window sash, reducing maintenance time and cost.
