Damping hinge with automatic closing, positioning and speed regulating functions

Abstract

The invention discloses a damping hinge with automatic closing, positioning and speed regulating functions. The damping hinge with the automatic closing, positioning and speed regulating functions is characterized in that: a door shaft penetrating from an upper hinge to a lower hinge is arranged in the damping hinge with the automatic closing, positioning and speed-regulating functions; the lower hinge part has a damping effect; the upper hinge part is provided with a positioning device and a torsion spring and has the automatic door closing and positioning functions; the upper part and the lower part are combined into a whole; the damping hinge has the functions of automatically closing a door, regulating the door-closing speed and positioning the door after the door is opened, so that the conventional door stopper is not required; a connecting sleeve in the middle is used for connecting the upper hinge and the lower hinge through the door shaft, so that an integral hinge with complete functions and stable performance is formed; the damping hinge with the automatic closing, positioning and speed regulating functions has the advantages of simple structure, convenience for assembly, low manufacturing cost and the like; and a hinge for doors and windows, which is convenient, safe and practical and has a moderate automatic door-closing speed and a positioning function, is provided.

Description

technical field [0001] The invention relates to a hinge, and in particular provides a door hinge with a simple structure and practical automatic door closure capable of speed regulation and positioning. Background technique [0002] At present, the existing hinges with automatic door closing function on the market convert the rotary motion of the door leaf into the linear motion of the plunger. The outer cylinder of the thread is processed with straight teeth and the inner tube of the door leaf of the speed-regulating hinge also has straight teeth. The two straight teeth occlude radially to fix the axial sliding. Sealing, oil leakage often, complex structure, difficult processing, high cost, low manufacturing efficiency and other shortcomings. Contents of the invention [0003] The purpose of the present invention is to provide a novel hinge which is economical, stable in use and capable of achieving ideal door opening and closing effects. [0004] In order to achieve th...
