Description

Multidirectional regulation blind hinge

Technical Field

The invention relates to a door and window hinge, in particular to a multidirectional adjusting blind hinge.

Background

The hinge shaft of the hidden hinge for the safety door (anti-theft door) is arranged in a door frame, and the door leaf and the hinge shaft are connected through a hinge arm, so the structure is relatively complex, especially the processing precision of the arched hinge arm is difficult to control due to the complex shape, and the tightness between the door leaf and the door frame is difficult to guarantee in the installation process. In addition, the hinge arm still works in a cantilever state, and after the hinge arm is used for a long time, the hinge arm is easy to deform and can damage the tightness between the door leaf and the door frame. Therefore, an adjusting mechanism is needed to adjust to repair the error of the part during the processing process and the problem of the sealing damage caused by the deformation during the use process.

Chinese patent document CN203175234U discloses a hidden hinge for a security door, which is provided with a rotating shaft, wherein the rotating shaft is connected with a hinge seat in a door frame, and comprises a door frame connecting section and a door leaf connecting section, the door frame connecting section is bent by a steel plate to form a shape of ∩, one end of the door frame connecting section is connected with a rotating shaft sleeve, the other end of the door frame connecting section is fixed with the door leaf connecting section through a fastener, and an adjusting hole is arranged between the two sections of hinges.

However, the above-mentioned blind hinge adjusting mechanism is mainly used for a single-shaft blind hinge, and such a unidirectional adjusting mechanism needs sufficient operation experience to meet the ideal sealing requirement between the door leaf and the door frame. However, in the case of the double-shaft blind hinge capable of being opened by 180 degrees, the factors affecting the installation adjustment and the sealing requirements of the door and the door frame, such as machining errors and deformation during use, become more complicated, and although patent document CN201850889U mentions that the double-shaft blind hinge can be used for the double-shaft blind hinge, the sealing requirements of the door and the door frame are difficult to achieve in practice unless there is no machining error or deformation during use and transportation. In order to achieve the adjustment intuitively and simply to achieve the required sealing requirement, chinese patent document CN201635554U discloses a three-way adjustable blind hinge, see fig. 10, comprising a hinge, a hinge coupling block, a fixing pin, an adjusting block, an eccentric pin, a fastening screw, an adjusting screw and a nut. Through the rotation of the two eccentric pins, eccentric motion is generated around the circular holes C1 and C2 respectively, the flat head parts of the two eccentric pins rotate in the strip-shaped holes C2 and E2 of the hinge respectively, so that the hinge and the hinge connecting block generate relative motion in the X direction and the Y direction, namely the adjustment in the X, Y direction is realized. Meanwhile, the distance between the hinge and the hinge connecting block can be adjusted by screwing in or out the adjusting screw, namely the distance adjustment of the hinge and the hinge connecting block in the Z direction is realized. The hinge can freely adjust the clearance in three directions of the door leaf, and the consistency of the clearance in three directions of the assembly of the door leaf and the door frame is ensured. In this prior art, the adjustment is actually achieved by the simultaneous engagement of the eccentric pins with the holes B1, B2, C1, C2 for simultaneous vertical and horizontal adjustment. Such an adjustment mechanism is still inconvenient to readjust if the vertical direction does not meet the requirements when the horizontal adjustment is appropriate.

Obviously, in the prior art, only the adjustment between two adjacent parts, namely two sections of hinge arms, is difficult to adjust the problem of untight sealing between the door leaf and the door frame caused by errors such as processing, installation, use deformation and the like among more parts.
