Description

Technical Field

[0001] The utility model belongs to the field of door and window hardware fittings, and particularly relates to a convenient-adjusting invisible hinge. Background Art

[0002] An invisible hinge is a common door and window hardware fitting. Generally, there are upper hinges and lower hinges according to different upper and lower positions of installation on doors and windows. The existing invisible hinges on the market usually do not have three-dimensional adjustment functions. Some invisible hinges can achieve three-dimensional adjustment to ensure the installation accuracy of door and window sashes, but their three-dimensional adjustment structures are relatively complex, and the operating space for installers during three-dimensional adjustment is small, making it inconvenient to operate. In addition, the existing three-dimensional adjustment structures often are close to the corner positions when the invisible hinge is opened. Since the corner positions bear a large load and are prone to wear, after wear occurs at the corner positions, three-dimensional adjustment needs to be carried out again to finely adjust the position of the door and window sashes, and the wear at the corners will have a certain adverse impact on the adjustment effect of the three-dimensional adjustment structure, thus affecting the stability of the overall structure of the invisible hinge. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an invisible hinge with good structural stability and convenient adjustment in view of the deficiencies of the prior art.

[0004] The technical solution adopted by the utility model to solve the above technical problems is as follows: A convenient-adjusting invisible hinge includes a bottom plate, a long support piece, a short support piece and a sash mounting member. One end of the long support piece is slidably connected to the sash mounting member, the other end of the long support piece is riveted to one end of the bottom plate, the middle part of the long support piece is cross-riveted to the middle part of the short support piece. One end of the sash mounting member is vertically provided with an adjusting seat. The adjusting seat is provided with a left-right adjusting screw, a first hexagon socket flat end set screw, a second hexagon socket flat end set screw, a steel ball and an up-down adjusting rivet. The left-right adjusting screw and the first hexagon socket flat end set screw are respectively horizontally installed on the adjusting seat. The screw head of the left-right adjusting screw abuts against the side surface of the adjusting seat. The second hexagon socket flat end set screw, the steel ball and the up-down adjusting rivet are vertically installed on the adjusting seat in sequence from top to bottom. The adjusting seat is riveted to one end of the short support piece through the up-down adjusting rivet. The other end of the short support piece is riveted with a front-back adjusting rivet.
