Abstract

The invention provides a door stopper, which belongs to the technical field of electric power tools, and comprises a door stopper body. The blocking part for closing the cabinet door, the doorstop provided by the present invention uses a doorstop body with a chute to match the chute with one side of the cabinet door of the transformer cabinet, and the two sides of the doorstop body are set to block The blocking part of the door of the transformer cabinet. After opening the door of the transformer cabinet, the staff does not need to attach themselves or squat down, and directly install the chute with the door of the transformer cabinet. The two side surfaces drop to the ground, and the cabinet door of the transformer cabinet is prevented from being automatically closed under the action of the blocking part. This method is easy to install. Even if the ground is uneven and the ordinary door stopper using the gap between the substation cabinet door and the ground cannot be used, the door stopper can still be used to prevent the automatic closing of the substation cabinet door.

Description

technical field [0001] The invention belongs to the technical field of electric auxiliary tools, and more specifically relates to a doorstop.
