Abstract

A door frame installation auxiliary device and its use method, comprising a U-shaped fixing bracket and a jacking component; one side arm of the fixing bracket is fixed to the wall through an anchor plate; the jacking component is a jacking bolt, installed on the fixing bracket, including The wall jacking assembly and the door frame jacking assembly, the wall jacking assembly and the door frame jacking assembly both include an X-direction jacking assembly and a Y-direction jacking assembly arranged vertically in the axial direction, and the two jacking assemblies from the X and Y directions respectively Tight on the wall and door frame. The device of the present invention adopts a detachable fine-tuning mechanism, which has a three-dimensional axial precise adjustment function. After adjustment, the positioning and fixing of the door frame can be realized by relying on the extrusion pre-tightening force at the contact rubber. The device has compact structure, simple and easy operation, and reliable performance. , which solves the problems of movement and inaccurate positioning during the installation of the door frame, and is widely used in the on-site installation and in-factory adjustment of auxiliary door frames such as small air defense doors, civil anti-theft doors and fire doors.
