In a specific embodiment, as shown in fig. 1 to 3, the cover shell 1 is an insulating cover shell, so that the field use requirement can be further met, and the safety of related personnel and equipment is ensured.
In a specific embodiment, as shown in fig. 1 to 3, the angle between the bottom surface of the handle 2 and the side surface of the locking hook 3 facing away from the hook portion 31 is 90 degrees, so that when the second end of the handle 2 is turned to move in the direction of the top surface near the end of the cover 1 in the length direction, the locking hook 3 moves forward and is locked with the fixing pin 41.
In a specific embodiment, the first end of the handle 2 is provided with an open slot open facing away from the second end of the handle 2, and the first end of the locking hook 3 is provided in the open slot, which can facilitate welding the first end of the handle 2 and the first end of the locking hook 3.
When the utility model is used, the handle 2 is in an open state, and the cover shell 1 is covered on the top of the socket 4 disconnected with the plug of the manual maintenance switch. The second end of the handle 2 is turned to move toward the top surface of the end portion close to the longitudinal direction of the cover 1, so that the hook portion 31 can be driven to rotate forward, and the hook portion 31 and the fixing pin 41 can be locked together. The hang tag is locked through the first through hole 21 and the second through hole 12 by means of a padlock. Before the padlock is removed, the socket 4 cannot be opened, so that potential safety hazards can be eliminated, and the safety of related personnel is ensured. When the socket 4 is required to be used, the padlock is removed, and the second end of the handle 2 is rotated to move toward the top surface of the end far from the cover 1 in the longitudinal direction, so that the hook 31 can be driven to reversely rotate, and the hook 31 can be separated from the fixing pin 41.
The scope of the present utility model is not limited to the above-described embodiments, and it is apparent that various modifications and variations can be made to the present utility model by those skilled in the art without departing from the scope and spirit of the utility model. It is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
