[0025] See also Figure 1-4 The utility model provides a technical solution: a bracket device for a switch, comprising a first mounting frame 1, a second mounting frame 8 and a fixing device, a switch body 2 is placed inside the first mounting frame 1, four connecting ears 3 are welded on the surface of the first mounting frame 1, bolts 4 are installed inside the four connecting ears 3, two threaded rods 5 are connected to the inner thread of the first mounting frame 1, the opposite ends of the two threaded rods 5 are rotatably connected to the pressure plate 7, the opposite ends of the two threaded rods 5 are welded to the rotating plate 6, and the two pressure plates 7 are in contact with the surface of the switch body 2;

[0026] When the bracket device for the switch is in use, the staff installs and fixes the first mounting frame 1 through four bolts 4, and then places the switch body 2 inside the first mounting frame 1, and finally rotates the threaded rod 5 through the turntable 6. The threaded rod 5 rotates and drives the pressure plate 7 to move and gradually squeeze on the surface of the switch body 2 through the threaded connection between the threaded rod 5 and the first mounting frame 1. Similarly, the staff uses the same placement to move and squeeze another pressure plate 7 on the surface of the switch body 2 to fix it. The two adjustable pressure plates 7 can fix switch bodies 2 of different sizes, thereby increasing the application range of the mounting bracket and improving the convenience of the mounting bracket for fixing switch bodies 2 of different sizes.

[0027] Two square clamping blocks 9 are welded on the top of the first mounting frame 1 and the second mounting frame 8, and two clamping holes 10 are provided on the surface of the four square clamping blocks 9. Two square clamping grooves 11 are provided on the bottom of the second mounting frame 8, and the surface of the square clamping block 9 is slidably connected with the inside of the square clamping groove 11;

[0028] The fixing device includes two slides 13, a spring 14, two pull rods 15 and four fixed shafts 16. A slide groove 12 is opened inside the second mounting frame 8. The two slides 13 are slidably connected inside the slide groove 12. The spring 14 is fixedly connected to the surfaces of the two slides 13. The two pull rods 15 are welded to the surfaces of the two slides 13. The four fixed shafts 16 are respectively welded to the surfaces of the two slides 13. The four fixed shafts 16 are slidably connected to the inside of the second mounting frame 8. The surface of the fixed shaft 16 is slidably connected to the inside of the card hole 10.

[0029] When multiple switch bodies 2 need to be installed, the staff can take out the second mounting frame 8, first slide the two slides 13 relative to each other through the two pull rods 15 and squeeze the spring 14. The sliding of the two slides 13 drives the two fixed shafts 16 to slide out of the two square card slots 11. Then, the staff slides the two square card blocks 9 on the top of the first mounting frame 1 into the two square card slots 11 through the second mounting frame 8. After loosening the two pull rods 15, the spring 14 releases the elastic force and drives the fixed shaft 16 to slide into the card hole 10 by pushing the two slides 13 to complete the assembly. By splicing and assembling multiple mounting brackets, the staff can assemble the brackets according to needs to install different numbers of switch bodies 2, thereby enhancing the practicality of the switch bracket device.

[0030] Working principle: The switch uses a bracket device. The staff puts the switch body 2 inside the first mounting frame 1 and rotates the threaded rod 5 through the turntable 6. The threaded rod 5 rotates and drives the pressure plate 7 to move and gradually squeeze on the surface of the switch body 2 through the threaded connection between the first mounting frame 1. Similarly, the staff uses the same placement to move and squeeze the other pressure plate 7 on the surface of the switch body 2 for fixing. The switch bodies 2 of different sizes can be fixed by two adjustable pressure plates 7. The staff takes out the second mounting frame 8. First, the two slide plates 13 are relatively slid through the two pull rods 15 and the springs 14 are squeezed. The sliding of the two slide plates 13 drives the two fixed shafts 16 to slide out of the two square card slots 11. Then, the staff slides the two square card blocks 9 on the top of the first mounting frame 1 into the two square card slots 11 through the second mounting frame 8. After loosening the two pull rods 15, the spring 14 releases the elastic force and drives the fixed shaft 16 to slide into the inside of the card hole 10 by pushing the two slide plates 13 to complete the assembly. The staff can assemble the bracket according to needs to install different numbers of switch bodies 2.
