AI Technical Summary

Technical Problem

In existing ground axis systems, the spring design of heavy-duty revolving doors is too large, causing the revolving door to swing in the open and closed positions, which poses a safety hazard. In addition, the installation cost is high, and concealed installation requires a larger pre-embedded groove.

Method used

The structure employs an upper hinge seat and a lower hinge seat, and drives the first and second moving elements to move linearly through an actuation element. It utilizes the first and second compression springs with different elastic coefficients to provide return elastic potential energy, thereby achieving stable opening and closing of the heavy-duty revolving door. It also uses smaller springs to facilitate concealed installation.

Benefits of technology

It achieves stable rebound positioning of heavy-duty revolving doors, reduces installation costs, and facilitates concealed installation of the ground axis, reducing the need for pre-embedded grooves.

Abstract

The utility model discloses a positioning rebounding ground shaft door control device, including for installing on the door leaf upper hinge seat and for installing on the ground lower hinge seat, the upper hinge seat includes seat body, pivot, first mobile element, second mobile element, actuating element, first compression spring and second compression spring, through setting first mobile element, second mobile element respectively at the both ends of actuating element, when the rotation of actuating element drives first mobile element to move linearly upward and drives second mobile element to move linearly downward, make first mobile element compress first compression spring while second mobile element compress second compression spring, provide enough return elastic potential energy for heavy rotary door, and when releasing elastic potential energy make the door body open / close more stable, actuating element drives first mobile element and second mobile element under the same rotation stroke, can adopt smaller spring compared with traditional structure, conveniently ground axle hidden type installation.
