[0026] In the specific implementation process, Figure 1-Figure 7As shown, the safety relay for monitoring dual safety matters includes a relay body 1, a cover plate 2 is installed at the bottom of the relay body 1, and the bottom diagonal of the relay body 1 is engaged with the diagonal corresponding to the cover plate 2 through a connecting component. It should be noted that the above-mentioned relay body 1 is as recorded in the publication number CN216389198U;
[0027] The connecting assembly includes a connecting sleeve 3, an adjusting rod 4 and a mounting plate 5. The connecting sleeve 3 is fixedly mounted on the cover plate 2. One end of the adjusting rod 4 is inserted into the connecting sleeve 3, and two opposite hinged connecting rods are respectively provided on the edge of the adjusting rod 4. It should be noted that the hinged connecting rod includes a fixing plate 10 and a connecting rod 11. The fixing plate 10 is fixedly mounted on the edge of the adjusting rod 4. The two ends of the connecting rod 11 are respectively hinged to the fixing plate 10 and the plug 6. The end of the adjusting rod 4 away from the fixing plate 10 is fixedly mounted with a turning handle 15. The other ends of the two hinged connecting rods are hinged with the plug 6. The outer surface of the connecting sleeve 3 is provided with a through groove 7 for the plug 6 to pass through. The mounting plate 5 is fixedly mounted on the relay The inner wall of the body 1 and the mounting plate 5 are provided with a positioning groove 8, the connecting sleeve 3 is clearance-matched with the positioning groove 8, and the inner wall of the positioning groove 8 is also provided with a clamping groove 9 matching the plug rod 6; when the turning handle 15 is turned to rotate the adjusting rod 4, the adjusting rod 4 drives the fixing plate 10 to rotate, so that the connecting rod 11 moves along the rotation direction of the fixing plate 10, and the plug rod 6 moves laterally in the through groove 7 under the drive of the connecting rod 11. When the plug rod 6 is inserted into the clamping groove 9 on the mounting plate 5, the connection between the relay body 1 and the cover plate 2 is completed, otherwise it is disassembled, and the installation and disassembly are completed by the connecting rod clamping method, so as to avoid the situation of plastic deformation caused by long-term use, and further improve the fixing effect of the safety relay;
[0028] It should be noted that, in order to prevent the adjusting rod 4 from rotating at an excessive angle, a limit column is provided within the range of rotation of the fixing plate 10, and the limit column is fixed to the inner wall of the connecting sleeve 3;
[0029] In order to protect the interface of the relay body 1, a protective baffle 12 is also provided at the interface of the relay body 1.

When the plug rod 6 is inserted into the card slot 9 on the mounting plate 5, the connection between the relay body 1 and the cover plate 2 is completed. Conversely, the installation and disassembly are completed by the connecting rod engagement method to avoid plastic deformation due to long-term use. When one end of the support rod 13 is inserted into the connecting hole 16 of the card block 14, the protective baffle 12 is opened and the line is connected normally. When the safety relay is not in use, the support rod 13 is moved out of the connecting hole 16, and the protective baffle 12 falls and covers the interface of the relay body 1.
