Description

Technical Field

[0001] The utility model relates to the technical field of hardware hinges, in particular to a square hinge. Background Art

[0002] Hinges are widely used in furniture. It includes a hinge cup and a connecting seat that are hinged to each other. The hinge cup is fixed on the door panel, and the connecting seat is equipped with a fixing seat fixed on the frame of the furniture. Among them, a transmission component is installed at the connection between the hinge cup and the connecting seat. The transmission component is connected with a damper so that the hinge cup can open and close smoothly relative to the connecting seat, and at the same time has a buffering effect to ensure the normal and stable use of the furniture.

[0003] Due to the installation error between the furniture frame and the door panel, an adjustment component for adjusting the installation position is installed on the hinge arm. This adjustment component generally includes a longitudinal adjustment screw and a transverse adjustment eccentric wheel. The longitudinal adjustment screw and the transverse adjustment eccentric wheel are used to adjust the longitudinal position and the transverse position between the movable frame and the hinge arm. When the longitudinal adjustment screw adjusts the fixing seat to move downward to the lowest position relative to the connecting arm, due to the fixing seat being pressed by the longitudinal adjustment screw, when the transverse adjustment eccentric wheel adjusts the fixing seat to move linearly back and forth relative to the connecting arm, it is restricted, and it is difficult to adjust the front and back positions of the hinge installation, which affects the normal use of the hinge.

[0004] With the continuous optimization of adjustable hinges, the existing adjustable hinges have achieved three-dimensional adjustment. For example, the three-dimensional adjustment hinge with the Chinese patent document publication number CN108999508A includes a hinge body, an adjustment seat and a base. The adjustment seat is arranged between the hinge arm of the hinge body and the base. The adjustment seat and the base are riveted at the folded edges on the front and back sides, and an eccentric adjustment rivet is riveted between the adjustment seat and the base. The eccentric part of the eccentric adjustment rivet is accommodated in the riveting hole of the adjustment seat, and the riveting hole is set as a long slot hole that only allows the eccentric part to move in the front and back directions. A rivet that passes through left and right is riveted between the hinge arm and the adjustment seat. The riveting holes on both sides of the adjustment seat are set as long slot holes that only allow the rivet to move in the front and back directions. A card slot is formed at the top of the adjustment seat. An adjustment screw threadedly connected to the top of the hinge arm is provided. The end of the adjustment screw forms a plug-in card head for plugging into the card slot. An eccentric adjustment wheel is installed at the top of the hinge arm. The eccentric adjustment wheel forms an eccentric shaft inserted into the top of the adjustment seat, and the insertion hole of the adjustment seat is set as a long slot hole that only allows the eccentric shaft to move in the left and right directions. This structure can adjust its installation dimensions in three-dimensional directions, but there are still some problems, including: 1. The eccentric adjustment wheel 6 and the adjustment screw 7 are prone to interference during adjustment, resulting in a situation where it is difficult to twist; 2. The adjustment seats are connected by a stacked structure, which is more prominent visually after the adjustment component is installed on the cabinet door. Summary of the Utility Model
