Adjustable column type hinge for doors and windows

Abstract

The invention discloses an adjustable column type hinge for doors and windows. The adjustable column type hinge comprises a leaf hinge assembly, a frame hinge assembly, a vertical adjuster, a hinge shaft and a shaft sleeve. An adjusting block and a clamping block I are fixed in a fan frame mounting groove, a fan hinge is positioned on the adjusting block through two clamping pieces, two shaft sleeves which are assembled on a hinge shaft in an interference mode are assembled in shaft sleeve holes of the fan hinge through key grooves, and the fan hinge is screwed and fixed on the adjusting block through an adjusting screw, a fastening screw and an adjusting bolt. One end of the two-frame hinge is installed at the upper end and the lower end of the hinge shaft through the shaft sleeve installation holes, the other end of the two-frame hinge is fixed to the door frame through the clamping block, and the limiting gasket is installed at the upper end of the hinge shaft. A vertical adjusting screw of the vertical adjuster abuts against the lower end face of the lower end frame hinge, and the base is fixed to the door frame. The hinge can be adjusted under the condition that the parts, installed on the hinge shaft, of the leaf and frame hinge are not staggered, so that the matching error between a door frame and the door leaf is eliminated, and the overall structure of the hinge is not damaged.

Description

technical field [0001] The invention belongs to the field of building doors and windows, and relates to an adjustable column hinge for an aluminum alloy door. Background technique [0002] The doors and windows of existing buildings generally include door and window frames and door and window leaves. The door and window frames and door and window leaves are connected together through hinges. Under the current technology, there are certain dimensional errors in the manufacturing process of the door and window frame leaves, resulting in the gap between the frame and the leaves. Coordination produces errors. Now the hinges for aluminum alloy doors and windows are mainly eccentric hinges, that is, adjust the relative positions of the hinge shaft, bushing and shaft hole to adjust the relative position of the door and window frame and the door and window leaf, and compensate for material deviation and installation deviation. , because this kind of hinge structure is adjusted by th...

[0002] The doors and windows of existing buildings generally include door and window frames and door and window leaves. The door and window frames and door and window leaves are connected together through hinges. Under the current technology, there are certain dimensional errors in the manufacturing process of the door and window frame leaves, resulting in the gap between the frame and the leaves. Coordination produces errors. Now the hinges for aluminum alloy doors and windows are mainly eccentric hinges, that is, adjust the relative positions of the hinge shaft, bushing and shaft hole to adjust the relative position of the door and window frame and the door and window leaf, and compensate for material deviation and installation deviation. , because this kind of hinge structure is adjusted by the eccentric shaft sleeve, the shaft sleeve will have an adjustable thickness, so the appearance gap of the hinge will inevitably increase, and because the shaft sleeve and the hinge body are both acting on the same hinge On the shaft, when adjusting the door and window frame or the door and window leaf, it will cause the upper and lower parts of the fan hinge and the frame hinge installed on the hinge shaft to be misaligned, thus affecting the overall aesthetics of the door and window

And this kind of hinge is complicated to install, and there are many parts affected during adjustment, which affects the service life of the hinge
