Publication number: 20250251072Abstract: A quick coupler assembly includes a male and a female coupler connected end to end. The male coupler includes a seat having a core pipe; and a sliding sleeve and a sleeve sequentially fitted around the core pipe. The female coupler includes a pipe member externally provided with a pipe sealing ring and internally provided with a movable valve head. The pipe member pushes the sliding sleeve backward when being connected to the sleeve of the male coupler, so that the pipe sealing ring and a sealing ring on the sliding sleeve form an outer side first seal mechanism in the sleeve of the male coupler. Meanwhile, the backward moved sliding sleeve allows a front end of the core pipe to enter into the pipe member, such that a front and a rear sealing ring on the core pipe form an inner side second seal mechanism in the sliding sleeve.Type: ApplicationFiled: February 20, 2024Publication date: August 7, 2025Inventor: An-Szu Hsu

Publication number: 20240353042Abstract: An alignment guiding sleeve for quick coupler includes a guiding sleeve having a closed engaging end provided with an engaging bore and an open guiding end defining a guiding bore and formed into a beveled guiding surface, and internally defining a guiding passage extending between and communicable with the engaging end and the guiding end. A male coupler can be assembled to the guiding sleeve by inserting through the engaging bore. The beveled guiding surface is adapted to guide a female couple into the guiding passage to connect to the male coupler. With the beveled guiding surface, any radial offset between the female coupler and the male coupler can be corrected, so that the female and the male coupler can be eventually aligned axially to connect together end to end without causing wear and incomplete watertight connection at the joint of the female and male couplers to result in leakage.Type: ApplicationFiled: July 2, 2024Publication date: October 24, 2024Inventors: An-Szu Hsu, Yan-Jiao Cheng
