AI Technical Summary
Technical Problem
The filter discs on existing elbow fittings cannot be removed, which means that the entire fitting needs to be replaced when the filter holes become clogged, increasing the cost of use.
Method used
A novel elbow pipe fitting structure is designed, which enables the detachable connection of the filter element through a threaded pipe and an installation mechanism. The threaded pipe is fixed by a limiting plate and a threaded rod with a fastening nut, facilitating the replacement of the filter element.
Benefits of technology

Abstract
The utility model belongs to the technical field of pipelines, and particularly relates to a novel elbow pipe fitting structure which comprises a pipe body, annular supporting plates are fixed to the interiors of the two ends of the pipe body, filtering pieces are arranged on one sides of the two annular supporting plates, threaded pipes are arranged in the interiors of the two ports of the pipe body in an inserted mode, and the two ends of the pipe body are each provided with a through hole. A threaded pipe is arranged in the pipe body, the end, extending into the pipe body, of the threaded pipe makes contact with the side wall of the filtering piece, a mounting mechanism is arranged outside the threaded pipe, and the threaded pipe is fixedly connected with the pipe body through the mounting mechanism. And the pressing force on the filter is relieved, so that the filter can be conveniently and quickly replaced, and the use cost is saved.
