AI Technical Summary

Technical Problem

The existing hinges have interconnected adjustment components in the X and Y axes, resulting in misalignment of the upper, middle, and lower hinges after adjustment. This affects the smoothness of movement and service life, while also compromising aesthetics.

Method used

Design a surface-mounted lower hinge that uses independent X-axis, Y-axis and Z-axis adjustment components to adjust the positions of the hinge plate, upper fixing plate and upper support respectively, and achieves independent adjustment in each direction by set screws and eccentric adjustment rivets.

Benefits of technology

This design avoids the problem of misalignment between the upper and lower hinges, simplifies the structure, improves the convenience of manufacturing and assembly, and enhances the aesthetics.

Abstract

This utility model belongs to the field of hinge technology, and specifically relates to an exposed lower hinge, including a bearing fixing connection seat, a bushing, a hinge plate connected to the bushing, upper fixing plates respectively disposed on both sides of the hinge plate, and an upper support. The lower end of the bushing is rotatably connected to the bearing fixing connection seat through a hinge shaft. A set screw is provided above the hinge shaft, and the upper part of the bushing is provided with an internal thread for the set screw. By adjusting the set screw, the bushing can be adjusted in the Y-axis direction, so as to ultimately achieve the overall adjustment of the hinge plate, upper fixing plate, and upper support in the Y-axis direction. This utility model has independently designed and adjusted the X-axis, Y-axis, and Z-axis directions separately, so that they do not interfere with each other. Therefore, it can avoid the problem of misalignment. Compared with the original adjustment component, it also simplifies the structure, facilitates manufacturing and assembly, has better structural versatility, and improves aesthetics.
