AI Technical Summary
Technical Problem
In existing cabinet door hinges, the height difference between hinge fulcrum A and B leads to insufficient swing space for the secondary swing arm, resulting in a small hinge opening angle and affecting the door opening angle.
Method used
Design a large-angle linkage, including a linkage body and an arc-shaped abutment part. By bending downward on one side of the hinge cup hinge end to form an angle, the movement performance of the hinge is optimized, enabling the door to achieve a larger opening angle within a limited space.
Benefits of technology
Without increasing the cabinet height, a 120° opening angle for the door is achieved, optimizing the hinge's movement performance and reducing the overall height, thus improving the overall aesthetic appeal of the space.

Abstract
This utility model belongs to the technical field of cabinet accessories, specifically relating to a large-angle connecting rod and hinge. It includes a connecting rod body and a base hinge end and a hinge cup hinge end disposed on the connecting rod body. The connecting rod body is bent downwards near the hinge cup hinge end to form an angle. The inner side of the angle is designed as an arc-shaped abutment portion, which abuts against the transmission connecting rod. Furthermore, the hinge of this utility model utilizes the large-angle connecting rod described above. This large-angle connecting rod is used in cabinet door hinges, with an angle on the side near the hinge cup hinge end. Through the geometric design of the angle, a larger door opening angle is achieved within a limited swing space, allowing the door opening angle to reach 120°.
