Of course, the contact manner between the blocking plate 83 and the moving portion 72 is not limited to this, the blocking plate 83 may contact with one side surface of the square tube on the moving portion 72 to limit the degree of freedom of movement of the moving portion 72, a protrusion may be provided on one side surface of the blocking plate 83, a groove adapted to the protrusion may be provided on the square tube on the moving portion 72 to limit the degree of freedom of movement of the moving portion 72, and the limitation of the degree of freedom of movement of the moving portion 72 may be achieved.
One end of the pull rod 84 is connected to the stopper 83 to drive the stopper 83 to rotate relative to the positioning shaft 82 to disengage from the stopper 81. For example, one end of the pull rod 84 is provided with a connecting hole, one end of the baffle 83 is provided with a connecting shaft, and the pull rod 84 and the baffle 83 are matched through a shaft hole to drive the baffle 83 to rotate relative to the positioning shaft 82. Thereby making the first locking mechanism simple and reliable in construction.
Specifically, the first locking mechanism 8 further includes a stop spring 85, the stop spring 85 is disposed on the positioning shaft 82 and contacts the first end of the baffle 83, and the stop spring 85 normally urges the baffle 83 to rotate toward the contact direction with the baffle 83. For example, the stop spring 85 is sleeved on the positioning shaft 82, and the central axis of the stop spring 85 is collinear with the central axis of the positioning shaft 82.
For example, as shown in fig. 9, when it is desired to move the electrical cabinet cover 7, the pull rod 84 is pulled to rotate the blocking plate 83 around the positioning shaft 82 and compress the stop spring 85, when the blocking plate 83 is disengaged from the stopper 81, the electrical cabinet cover 7 can move relative to the protective cover assembly 1, and then the blocking plate 83 is reset under the action of the spring force. This simplifies the operation and improves the usability of the first lock mechanism 8.
