Sep 21,2020
On February 21, 2025, according to the information of the National Intellectual Property Administration, Hangzhou Jiaxiang High - Strength Bolt Co., Ltd. obtained a patent entitled "An Anti - slip High - Strength Bolt Gasket", with the authorization announcement number CN 222502374 U and the application date of May 2024. The disclosed anti - slip high - strength bolt gasket of this utility model includes a lower gasket, an upper gasket, and a rubber anti - slip mat. Both the lower gasket and the upper gasket are provided with screw holes inside. Multiple teeth are fixedly arranged on the top of the lower gasket and can be inserted into the corresponding tooth grooves of the upper gasket. An annular installation groove is opened on the side wall of the upper gasket, and the rubber anti - slip mat is attached to the inner wall of the annular installation groove. By setting the rubber anti - slip mat, teeth, and tooth grooves, when the screw is sleeved inside the two screw holes, the rubber anti - slip mat can increase the friction force with the object to be connected, improving the anti - slip effect. The teeth inserted into the corresponding tooth grooves can limit the lower gasket and the upper gasket, achieving high - strength installation and ensuring that the rubber anti - slip mat is stably attached to one side of the object to be connected.
