Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a reinforced high-voltage clamp structure. Background Art

[0002] The power engineering is a project related to the production, transmission and distribution of electric energy. When fixing and installing the power equipment in the power engineering, a clamp structure is needed to lock and position the equipment. However, when installing the power facilities, the existing clamp structure needs to be locked by the locking cooperation of the bolt and the nut. When the nut is locked on the bolt to tighten the clamp, the bolt is prone to self-rotation because there is no force between the bolt itself and the clamp, resulting in the nut cannot be quickly locked on the bolt. Therefore, during the locking process of the bolt and the nut, the staff is also required to position the bolt by hand or with tools, which is more troublesome to use overall. Utility Model Content
