Piston type hidden hinge capable of being adjusted in six directions

Abstract

The invention provides a hinge used on a door or a window and particularly relates to a piston type hidden hinge capable of being adjusted in six directions. The piston type hidden hinge capable of being adjusted in the six directions comprises a left base and a right base; an upper columnar track determination groove and a lower columnar track determination groove are arranged on the bases; a columnar movable plug is arranged inside each columnar track determination groove; the piston type hidden hinge capable of being adjusted in the six directions further comprises four connection sheets; two of the four connection sheets are respectively arranged on the left base and the right base through two adhesion shafts, and the other two connection sheets are mounted in the columnar movable plugs on the left base and the right base through two movable shafts; the connection sheet on the left base and the connection sheet on the right base are integrally hinged through a spindle; the surfaces of both ends of the bases are respectively provided with an adjusting board and a movable board; a front-and-back adjusting screw is arranged between the adjusting board and the movable board; an upper-and-lower adjusting screw is arranged on the movable board on the right base; and a mounting hole is arranged on the movable board. With the adoption of the piston type hidden hinge capable of being adjusted in the six directions comprises provided by the invention, the bearing force of the hinge is enhanced; the hinge is naturally switched on without resistance, and the service life is prolonged; and the hinge can be adjusted in the six directions, i.e. a front direction, a back direction, an upper direction, a lower direction, a left direction and a right direction without dismounting the door and frames, and can be opened by 180 degrees.

Description

technical field [0001] The invention relates to a hinge for doors and windows, in particular to a piston-type concealed hinge that can be adjusted in six directions. Background technique [0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow rotation between them, the most common being a hinge installed on doors and windows. Due to the unavoidable problems of insufficient force and sagging affecting the opening of doors and windows during the use process, and also because of various reasons such as the error of the size and shape of the door opening, the error of the processing accuracy of the door itself, and the unskilled installation workers, etc., the door leaf and the door frame appear. The uneven interval between the doors affects the opening and closing of the door, and a lot of time and energy have to be spent on adjustments during installation, adjustment and use.

Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcomings of the existing hinges, which are insufficient in bearing force during use, easy to sag to affect opening, and take a lot of time to adjust during installation and use, and to invent a piston-type six-way adjustable hidden hinge. The adjustment mechanism on the hinge can quickly eliminate the position error between the door and window sash and the door and window frame, and easily complete the installation and long-term use of the door and window
