Description

Technical Field

[0001] The utility model relates to a hinge, which is a self-resetting hinge. Background Art

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow rotation between them; it is mainly used for opening or closing door panels on products such as cabinet doors. Some of the hinges currently used in the industry are one-way reset hinges, which require corresponding limiting features on the door frame and can only be opened on one side. For this reason, other hinges achieve two-way reset through a two-way torsion spring structure on both sides; such as the application number 202021186514.8 disclosed in the Chinese patent literature, the authorization announcement date 2021.06.18, and the utility model name "spring hinge"; however, the torsion spring of this type of hinge is placed in the shaft hole, which can easily cause the force-bearing shaft area to be too small, and various deformations and sagging are prone to occur during use. At the same time, it is difficult to apply to the rocker arm structure of the charging pile. The existing charging pile rocker arm structure, such as the application number 202321633402.6 disclosed in the Chinese patent literature, the authorization announcement date is 2024.01.09, and the utility model name is "an electric vehicle charging device"; but the charging pile rocker arms of car companies such as Sunshine, Huawei, Xingxing, and Weilai currently require that the hinges have no sagging problems and have a self-resetting function. The existing hinges are difficult to meet the charging pile rocker arm requirements of the above-mentioned car companies. Summary of the invention
