[0021] In the following, embodiments of the switch status indicating device of the present utility model will be described with reference to the accompanying drawings.

[0022] Figures 1-4 A switch status indicating device showing an embodiment of the present utility model includes a switch status indicator 1 and an installation frame 2: positioning pins 14 are fixedly connected to the four corners of the rear side of the switch status indicator 1, positioning holes 15 for inserting the positioning pins 14 are provided at the four corners of the front side of the installation frame 2, mounting counterbores 16 are provided at both ends of the front side of the installation frame 2, a wiring panel 3 is arranged at the rear side of the switch status indicator 1, the surface of the wiring panel 3 is attached to the inner wall of the installation frame 2, a hook 4 is fixedly connected to the top of the rear side of the switch status indicator 1, a rectangular cavity 5 for inserting the hook 4 is provided at the top of the front side of the installation frame 2, a movable pressing plate 6 is arranged through the top of the installation frame 2, a pushing plate 7 is fixedly connected to the bottom of the pressing plate 6 and extends into the inner cavity wall of the rectangular cavity 5, a block 8 engaged with the hook 4 is fixedly connected to the top of the pushing plate 7, a first wedge surface 12 is arranged on the front side of the block 8, a second wedge surface 13 adapted to the first wedge surface 12 is arranged on the rear side of the hook 4, round holes 9 are provided on both sides of the bottom of the inner cavity of the rectangular cavity 5, guide rods 10 sliding in the inner cavities of the round holes 9 are fixedly connected to both sides of the bottom of the pushing plate 7. By the cooperation of the round holes 9 and the guide rods 10, the guide rods 10 will slide in the inner cavities of the round holes 9 when the pushing plate 7 moves, providing guidance and limitation for the movement of the pushing plate 7 and improving the stability of the up and down movement of the pushing plate 7. A spring 11 is sleeved on the surface of the round hole 9, and both ends of the spring 11 are fixedly connected to the pushing plate 7 and the inner wall of the rectangular cavity 5 respectively.

[0023] Working principle: When the utility model is used, the user installs the installation frame 2 in the switch cabinet through the installation countersunk hole 16, then passes the line in the switch cabinet through the installation frame 2 and connects it to the rear side of the wiring panel 3, picks up the switch status indicator 1, and inserts the wiring panel 3 into the inner cavity of the installation frame 2 until the hook 4 is inserted into the inner cavity of the rectangular cavity 5. During this period, the wedge-shaped surface 2 13 on the hook 4 contacts the wedge-shaped surface 1 12 on the card block 8 to drive the card block 8 to move downward, and the card block 8 drives the guide rod 10 to slide in the inner cavity of the circular hole 9 and squeeze the spring 11. When the hook 4 is completely When entering the inner cavity of the rectangular cavity 5, the hook 4 cancels the thrust on the block 8, and the restoring force of the spring 11 causes the push plate 7 to drive the block 8 to move upward to the inner side of the hook 4, limiting the hook 4 to prevent the hook 4 from being separated from the inner cavity of the rectangular cavity 5, thereby realizing the installation of the switch status indicator 1. When removing the switch status indicator 1, it is only necessary to press the pressing plate 6 so that the push plate 7 drives the block 8 to move downward, cancel the limit on the hook 4, and pull the switch status indicator 1 toward the front side so that the hook 4 on the switch status indicator 1 is separated from the inner cavity of the rectangular cavity 5 and can be removed.

[0024] To sum up: the switch status indicating device is implemented by installing the mounting frame 2 in the switch cabinet, picking up the switch status indicator 1, inserting the wiring panel 3 into the inner cavity of the mounting frame 2, and then inserting the hook 4 into the inner cavity of the rectangular cavity 5. The wedge surface 2 13 on the hook 4 contacts the wedge surface 1 12 on the card block 8 to drive the card block 8 to move downward and squeeze the spring 11. When the hook 4 completely enters the inner cavity of the rectangular cavity 5, the card block 8 moves upward due to the elastic force of the spring 11 and engages with the hook 4, so that the switch status indicator 1 can be installed. When disassembling, it is only necessary to press the pressing plate 6 downward to pull the switch status indicator 1 outward and remove it from the mounting frame 2, so as to achieve the purpose of quick disassembly and assembly of the switch status indicator and convenient inspection and maintenance of the switch cabinet by using the press-to-unlock method.
