Quick connection structure of activated carbon filter core for drinking water purification

Abstract

This utility model discloses a quick-connect structure for activated carbon filter cartridges used in drinking water purification, relating to the field of water filtration technology. It includes two sets of fixed shells. Sliding plates are slidably connected to the inner walls of the fixed shells, and a filter cartridge is slidably connected between the two sliding plates. A guide groove is provided on the outer wall of the fixed shell, with a limiting slot on one side. An inclined groove one and an inclined groove two are respectively provided at both ends of the guide groove. A fixed post is fixedly connected to the bottom end of the sliding plate, and a spring is embedded inside the fixed post. A rotating shaft is rotatably connected to the outer wall of the sliding plate, and a swing rod is fixedly connected to the outer wall of the rotating shaft. A sliding post is provided at one end of the swing rod. In this utility model, when the sliding plate extends or retracts, the sliding post moves within the guide groove and achieves temporary positioning by engaging with the limiting slot. When the sliding plate is pulled outward until the sliding post contacts the inclined groove two, the inclined groove two pushes the swing rod to rotate, causing the spring to engage with the slot, thereby locking the position of the sliding plate and facilitating quick installation or removal of the filter cartridge.
