Description

Technical Field

[0001] The invention relates to the field of electric iron accessories, in particular to an electric iron accessory with a double-head fixing structure. Background Art

[0002] Iron accessories are the common name for components (accessories) used in power transmission and transformation of power lines. They are non-standard products produced according to the special requirements of users, covering components for 10kV and below, 35kV, 110kV, 220kV transmission lines and substations, as well as some non-standard parts used in transportation and municipal administration.

[0003] The crossarm is a commonly used iron accessory with a porcelain bottle on it, which is used to support overhead transmission lines. The existing crossarms generally use angle irons, which are installed by drilling holes in the angle irons and using bolts and other mounting parts. Due to different installation positions, the required angle iron sizes are different. Therefore, when using them, they need to be cut and punched in advance according to the installation size, which easily causes waste of materials and inconvenience in installation. In addition, the existing angle iron crossarms have poor shock absorption effect due to the rigid connection, and are easily damaged and deformed by external forces.

[0004] Therefore, there is an urgent need for an electric iron accessory with a double-head fixing structure that can solve the above problems. Summary of the invention
