Portable auxiliary structure for mounting civil air defense door of civil air defense engineering

Abstract

The invention discloses a portable auxiliary structure for mounting a civil air defense door of civil air defense engineering. The structure comprises a bottom plate, wherein universal wheels are mounted at four corners of the bottom end of the bottom plate; a circular hole is formed in the middle part of the top end of the bottom plate; a storing groove is formed in the middle part of the bottomend of the circular hole; a sawtooth plate is arranged in the middle part of the inner wall of the storing groove; and a disc is welded in the middle part of the top end of the sawtooth plate. The structure is scientific and reasonable, and safe and convenient to use; the angle of a rotating plate can be conveniently adjusted through the storing groove, the circular hole, the sawtooth plate, the disc, a sawtooth rod, a second lead screw, a turntable and a circular rod, so that the angle of a clamping mechanism can be adjusted, and the difficulty in angle adjusting of the clamping mechanism isreduced; and meanwhile, the adjusted angle of the rotating plate can be fixed, thus the circumstance that an existing auxiliary mounting structure of the civil air defense door is inconveniently subjected to angle adjusting, and thus the mounting error of the civil air defense door is high can be solved; and in addition, the structure is simple to operate, and convenient to use.

Description

technical field [0001] The invention relates to the technical field of civil air defense engineering, in particular to a convenient auxiliary structure for installation of civil air defense doors in civil air defense engineering. Background technique [0002] The civil air defense door is the door of the entrance and exit of the civil protection project. The classification of the civil air defense door is relatively clear. The government mobilizes and organizes the masses, adopts anti-aircraft raids, disaster relief measures, implements rescue operations, prevents and mitigates disaster hazards, and civil air defense doors belong to civil defense protection equipment. For this reason, a Chinese patent discloses an installation assistance for civil air defense engineering protective doors. structure, the authorized announcement number is (CN 208932888 U), this patent can make the installation angle adjustment of the air defense door more convenient by adjusting the angle adju...

AI Technical Summary

Problems solved by technology

[0003] However, this patent also has the following disadvantages. After the installation angle of the civil air defense door is adjusted, there is no device for limiting the angle, which causes the installation angle of the civil air defense door to be adjusted to rotate, thereby requiring the staff to adjust the installation angle of the civil air defense door again. Adjustment, increasing the time for staff to adjust the angle
