A pressure spring energy storage and energy discharge conversion mechanism

Abstract

The invention relates to a pressure spring energy storing and energy releasing switching mechanism. The pressure spring energy storing and energy releasing switching mechanism comprises a center shaft (1) which is integrally cylindrical. A longitudinal hole (108) is formed along the axis of the center shaft (1) and is internally provided with a door closing force control mechanism, a check ring (8) is arranged on the upper portion of the center shaft (1) in a sleeved mode, a movable check ring (10) is arranged on the lower portion of the center shaft (1) in a sleeved mode, and a pressure spring (9) is arranged between the check ring (8) and the movable check ring (10). The pressure spring energy storing and energy releasing switching mechanism is arranged in a multifunctional shaft core of a hinge, a user only needs to screw an adjusting screw in the mechanism to enable a taper degree drawing down part at the lower end of the adjusting screw to longitudinally move to the appropriate longitudinal deep position, and therefore before the hinge is installed, the shaft core can be opened freely, and installation is convenient; after the hinge is installed, the hinge can have the automatic door closing function, and using is more convenient.

Description

technical field [0001] The invention relates to a pressure spring adjustment mechanism of a self-closing door hinge, in particular to a pressure spring energy storage and energy discharge conversion mechanism. The pressure spring energy storage and energy discharge conversion mechanism is assembled in the multifunctional shaft core of the hinge, especially the self-closing door hinge with automatic door closing function. Background technique [0002] At present, self-closing hinges are mostly reset by torsion springs. It is difficult, complicated, and limited by conditions to adjust the closing force. Moreover, torsion springs with high wire strength are easy to break the legs, and torsion springs with low wire strength are easy to fatigue and relax, so that the self-closing The closing function (automatic door closing function) is prone to failure. [0003] The existing self-closing door hinges using pressure springs do not have the ability to adjust the energy storage and...

Problems solved by technology

[0002] At present, self-closing hinges are mostly reset by torsion springs. It is difficult, complicated, and limited by conditions to adjust the closing force. Moreover, torsion springs with high wire strength are easy to break the legs, and torsion springs with low wire strength are easy to fatigue and relax, so that the self-closing The closing function (automatic door closing function) is prone to failure

[0003] The existing self-closing door hinges using pressure springs do not have the ability to adjust the energy storage and discharge of the pressure springs, and cannot realize that the hinges can be automatically closed (with automatic door closing function) and freely rotated (the shaft core can be opened freely) The conversion of the function (free rotation of the hinge and the switching of the automatic door closing function) brings inconvenience to the user
