Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 3, a screen cabinet lock device of a substation relay protection device, a lock head 1 is fixed on a left cabinet door, a lock body shell 3 is fixed on a right cabinet door, and the lock head 1 and the lock body shell 3 are horizontally opposite. The lock body shell 3 is provided with a square hole 3-1.
A sliding sleeve 10 is fixed inside the lock body shell 3, and the right end of the lock rod 2 is installed in the sliding sleeve 10 in a sliding fit mode. The left end of the lock body shell 3 is provided with a hole, and the left end of the lock rod 2 is slidably arranged in the hole at the left end of the lock body shell 3. A spring 9 is arranged between the left end of the lock rod 2 and the lock body shell 3, a step matched with the spring 9 is arranged on the lock rod 2, and the spring 9 gives a force for the lock rod 2 to move rightwards. The right end of the lock body shell 3 is provided with an elastic pad 8 at the position opposite to the right end of the lock rod 2. The lock rod 2 is internally fixed with a maintenance board 7 and an operation board 4. The left end of the lock rod 2 extends out of the lock body shell 3 and is matched with the lock head 1; a locking plate 5 is fixed at the left end of the locking rod 2, and a rectangular hole is formed in the end part of the locking plate 5; a lock ring 6 matched with the lock plate 5 for use is fixed on the left cabinet door.
