Adjustable hinge

Abstract

The invention discloses an adjustable hinge. The adjustable hinge comprises a left hinge, a right hinge and a shaft lever; each of the left hinge and the right hinge comprises a base plate and a shaft sleeve, wherein each base plate is provided with a fixing hole for mounting; each shaft sleeve is formed by outwards extending one side edge of the base plate and bending and curving toward one side of the upper surface of the base plate; an outwards convex shaft ring is arranged in the middle part of the shaft lever, which divides the shaft lever into an upper section and a lower section; the shaft sleeves of the right hinge and the left hinge are respectively rotatably connected with the upper section and the lower section at two sides of an upper shaft ring of the shaft lever; an adjusting bolt is in threaded connection with the inner lower end of the shaft sleeve of the left hinge, far from the shaft ring; the inner end surface of the adjusting bolt is connected against the end surface of the lower section of the shaft lever; reinforcing sheets which are clung to the upper surfaces of the base plates outwards extend from the side edges of openings in the shaft sleeves of the left hinge and the right hinge; the reinforcing sheets pass through the fixing holes for mounting in the base plates. With the adoption of the adjustable hinge, the upper and lower gaps between a door and a door frame can be adjusted, the shaft sleeves are high in intensity, and thus the phenomenon that the shaft sleeves are expanded and opened when using the hinge can be avoided; the processing is convenient; the production efficiency is high; in addition, printed patterns are high in quality.

Description

technical field [0001] The invention relates to a connecting member for installing doors and windows, in particular to a hinge with high structural strength and adjustable axial relative positions of left and right leaf pieces. Background technique [0002] Hinges are basic hardware used for door and window installation. Common hinges generally include left and right leaves with fixing holes. A number of shaft sleeves formed by extending outward and bending and curling. The shaft sleeves of the left and right sheets are arranged in an axially misaligned order. superior. When in use, the base of one leaf is fixed on the side of the door or window with screws, and the base of the other leaf is correspondingly fixed on the side of the door frame or window frame, so that the door or window can be opened and closed by rotation. . With the advancement of technology, new types of hinges continue to appear, such as printed hinges with convex patterns on the sheets. A "hinge" is ...
