However, the top of the switch cabinet does not have other facilities such as components for safety belt suspension, which brings great inconvenience to the maintenance work on the top of the cabinet. Therefore, it is necessary to develop a high-voltage switchgear safety belt hanger.

The patent document with the publication number CN107275961A discloses a safety belt suspension device for a high-voltage switchgear, which includes two connectors, two insulating rods and a pull rope device. The connector is a section of column, and the upper part of the column is provided with a concave The circular or square blind hole, or the concave opening slot, the blind hole or the opening slot is used in conjunction with the lower part of the insulating rod provided with the blind hole or the opening slot. It consists of a retractor, a belt rope, a hook, a hanging ring and a slip ring. The retractor is set on the upper end of one of the insulating rods. The belt rope is composed of two sections. The long section is wound on the retractor. A hanging loop or a hook is arranged at the end, and a short section is arranged on another insulating rod. The suspension device can be used for the staff to hang the safety belt when working on the top of the cabinet, which will not violate the regulations on electric safety work, and eliminates the potential safety hazard of the staff falling from the top of the cabinet to the ground, and improves the work of maintenance personnel to a certain extent. efficiency. However, the suspension device is provided with an open slot on the upper part of the connector, and the insulating rod is connected to the open slot by a pin shaft, so the insulating rod is prone to offset, and there is a potential safety hazard of instability.
