Patent number: 11460133Abstract: A tube connector has a main body, a restricting element, and a sealing ring. The main body has a mounting segment extending outwardly and transversely to form an inner annular space to accommodate the restricting element and the sealing ring. When the tube body is inserted, the tube body will be engaged and positioned by teeth of the restricting element. The sealing ring and the restricting element abut each other to maintain the sealing from the sealing ring. The changes of the pressure from the fluid transporting in the tube body will move the tube body and the main body relatively to and fro, and thus the abutting force against the sealing ring will increase or decrease accordingly, which maintains the elasticity of the sealing ring to maintain the sealing after a long time of use, thereby avoiding elastic fatigue and prolonging the lifespan.Type: GrantFiled: August 26, 2020Date of Patent: October 4, 2022Inventors: Hsin Cheng Kuo, Hung Cheng Kuo

Patent number: 11454339Abstract: The invention provides a quick-locking union connector. A sealing groove is arranged on the outside peripheral surface of a male inner sleeve to retain an o-ring seal. Close contact of the o-ring seal with the inside peripheral surface of a female outer sleeve leads to a robust sealing effect. The female outer sleeve is provided with a bore slot that penetrates through the inside peripheral surface, in an outside-to-inside manner. A locking unit rotates within the bore slot to quickly lock and unlock the engaged interior male unit and exterior female unit. Locked connection of pipes via obstructing protrusion of the locking unit into an annular locking groove can be readily and quickly executed, facilitating accelerated deployment of pipe networks.Type: GrantFiled: June 19, 2020Date of Patent: September 27, 2022Assignee: TOP GREAT PNEUMATIC MACHINERY CO., LTD.Inventors: Chieh-Yao Ting, Shang-Chieh Ting

Patent number: 11434699Abstract: This invention builds up on technical features and on the industry experience with the use of Merlin™ family connectors. In addition to friction, structural means utilized in order to transfer high torsional loads include: dog-clutch teeth, shear pins, keys, splines and interlocked thread systems, all used in isolation or in arbitrary combinations. Static and fatigue bending load capacities of the connectors remain high, while the axial load capacities may or may not be high, depending on the design requirements. Connectors according to this invention can be built as new, carefully optimized designs. In some cases upgrading existing Merlin™ family connector designs to increase they torque transfer capacities may be also feasible.Type: GrantFiled: April 18, 2016Date of Patent: September 6, 2022Inventor: Krzysztof Jan Wajnikonis
