A ferrule connector structure with built-in filter

Abstract

This utility model relates to the field of compression fitting technology and discloses a compression fitting structure with an internal filter. It includes a fitting body, one end of which is fixedly connected to a threaded tube. Both the fitting body and the threaded tube have slotted grooves on their inner sides, and fixed posts are fixedly installed inside each slot. By fitting a slider onto the fixed posts, the connecting seat and filter element are assembled into the fitting body. Then, the connecting pipe is installed onto the threaded tube. Simultaneously, the positioning post on the clamping block drives the movable rod to press against the annular groove, continuously pushing the slider to slide. The fixed posts are in a compressed state, thus completing the installation of the filter element for use with the filter medium. Disassembling the connecting pipe allows the movable rod to disengage from the annular groove, and then a spring and push ring push the slider to slide, facilitating the ejection and disassembly of the connecting seat and filter element. Compared to disassembling multiple bolts, this method is more time-saving and labor-saving, making it easier to clean the filter element and ensuring its filtration performance.
