Abstract

The invention provides an automobile coating system pipeline access door which comprises a heat insulation door frame, a heat insulation door, a handle lock and a door spindle assembly. The heat insulation door frame is connected with the heat insulation door through the door spindle assembly, the door spindle assembly comprises a door spindle boss and a door spindle recess, the door spindle boss is inserted into the door spindle recess to be welded with the edge of the heat insulation door, and the door spindle recess is welded with the heat insulation door frame. The handle lock is installed in a reserved hole in the heat insulation door. Heat insulation rock wool is filled between the heat insulation door frame and a door lining plate, and the door lining plate is welded and fixed with the heat insulation door. A heat insulation layer wraps the outer wall of a whole pipeline. The heat insulation door frame is fixedly connected with a pipeline wall plate through a flange hole in a strengthening flange frame. The automobile coating system pipeline access door can meet functional demands of like products and is simple in manufacture process, low in cost and quick, convenient and safe to use, the defect that cold penetrates existing access door frames is overcome, and the service life of the products is prolonged.

Description

technical field [0001] The invention relates to a pipeline inspection door for an automobile painting system, which belongs to the technical field of environmental protection ventilation products. Background technique [0002] Automobile painting system pipe inspection door, also known as inspection door and maintenance door, is installed and used in the ventilation pipe system of the current automobile assembly and painting production line. Among the inspection doors currently used, the manufacturing process is complicated, and there are many additional connecting parts such as hinges and buckles, and the connecting parts between the door and the pipeline are cumbersome and costly. Although some inspection doors are more meticulous in design ideas, their complex structures and cumbersome processing techniques make it difficult to achieve their expected functions and effects, such as complex sealing structures, cumbersome connections between doors and door frames, etc., and ...
