On November 30, 2024, financial news reported that the National Intellectual Property Administration's information shows that Handan Yongte Fastener Manufacturing Co., Ltd. has obtained a patent for a product called 'A Sealing Fastener', with authorization announcement number CN 222067862 U, and the application date is April 2024.
The patent summary indicates that this utility model belongs to the technical field of fasteners, specifically a sealing fastener, which includes two connecting buckles used for sealing and fastening the joints of pipes. The inner side of the connecting buckle is provided with a hollow groove, and the inside of the connecting buckle has a through groove that communicates with the hollow groove. An active sealing plug is movably connected inside the through groove, and the top of the active sealing plug is equipped with a connecting rod. When the sealing between the connecting buckle and the pipe is good, the sufficient gas inside the hollow groove and the through groove will push the connecting buckle, connecting rod, and connecting plate outward. Conversely, when the sealing effect between the connecting buckle and the pipe is poor, the gas inside the through groove exerts less force on the active sealing plug. The tension from the spring will cause the active sealing plug, connecting rod, and connecting plate to move towards the hollow groove. Therefore, by observing the position of the connecting plate, one can intuitively determine the sealing condition between the connecting buckle and the pipe, which is beneficial for timely maintenance when the sealing effect is not satisfactory.
