Embodiment Construction

[0006] During specific implementation, first make the internal fixed shaft, and then make the movable connection part into two upward spiral slopes (but the radius remains unchanged), and the structures just mesh with each other to form a hollow cylinder (the internal shaft is used to fix the rotation position). The contact part should be as smooth as possible to reduce the rotation resistance, which can also avoid the wear of a single inclined plane; at the same time, multiple tangent points can be reliably connected to the fixed piece, which can enhance its mechanical strength. The slope of the spiral slope is designed with reference to the door weight and required closing force.

Abstract

The invention relates to an automatic closing device for closing the door, which can solve problems of automatic closing mechanics. The invention uses screw inclined surface, which depends on the self gravity of door to automatically close the door. It can be used in variable doors.

Description

technical field [0001] The invention relates to a door hinge, especially a hinge that can be closed automatically. Background technique [0002] Most of the hinges currently used cannot realize automatic closing; there are also some hinges that are automatically closed, and most of them use elastic deformation such as springs or magnetic force to achieve automatic closing, but the closing ability will decrease due to elastic fatigue or magnetic fading over time. At the same time, the shape of the general spring is relatively small, and it is easy to break after corrosion, and the opening angle of the door is related to the elastic deformation, which will cause uneven torque. Such schemes are not very reliable in use. Contents of the invention [0003] It can be seen that we need to solve the problems of reliability of hinge closure and uniform torque. [0004] The present invention uses the self-weight of the door to act on the inclined surface of the hinge to achieve th...
