Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: an easy-to-install automatic control instrument, including a housing 1. Slider 16 is symmetrically fixedly arranged on the inner wall of the housing 1. An instrument body 17 is slidably arranged on the surface of the slider 16. Quick-release mechanisms are provided on the top and bottom inner walls of the housing 1. The quick-release mechanisms include mounting cavities 18 symmetrically opened on the inner wall of the housing 1. Fixing rods 19 are symmetrically fixedly arranged at both ends of the mounting cavity 18. Moving plates 20 are slidably arranged on the surface of the fixing rods 19. The two sets of fixing rods 19 are fixedly connected by a limiting plate 21. An inclined surface 22 is opened on the surface of the limiting plate 21, and the outer surface of the limiting plate 21 is flush with the mounting cavity 18. Several return springs 23 are elastically arranged between the inner walls, and the limiting plate 21 limits the instrument body 17. When installing the instrument body 17, simply slide the instrument body 17 along the slider 16 into the inner cavity of the housing 1. When the instrument body 17 enters the inner cavity of the housing 1, it will drive the limiting plate 21 to slide along the fixed rod 19 and squeeze the return springs 23. After the instrument body 17 is installed, the return springs 23 rebound and drive the limiting plate 21 to quickly reset and limit the instrument body 17. The installation of the instrument body 17 is more convenient, efficient and stable, reducing the installation error rate and improving the practicality and installation efficiency of the device.

[0024] like Figure 1-4 As shown, insertion holes 13 are provided at the four corners of the outer surface of the housing 1. A first sealing cavity 14 and a second sealing cavity 15 are sequentially provided on the outer surface of the housing 1 from the inside to the outside. An insertion rod 10 is inserted into the inner cavity of the insertion hole 13. A silicone sealing ring 11 is inserted into the inner cavity of the first sealing cavity 14. A fluororubber sealing ring 12 is inserted into the inner cavity of the second sealing cavity 15. The outer ends of the insertion rod 10, the silicone sealing ring 11, and the fluororubber sealing ring 12 are fixedly connected by a cover plate 8. A second magnet 9 is symmetrically fixed to the outer wall of the cover plate 8. The outer surface of the housing 1 is connected to the first... Two magnets 9 are symmetrically fixed at corresponding positions with the first magnet 7, and the first magnet 7 and the second magnet 9 are magnetically connected. When sealing the instrument body 17 installed in the housing 1, the insertion rod 10 is aligned and inserted into the insertion hole 13. At this time, the silicone sealing ring 11 is inserted into the first sealing cavity 14 and the fluororubber sealing ring 12 is inserted into the second sealing cavity 15. Under the magnetic attraction between the first magnet 7 and the second magnet 9, the cover plate 8 seals the housing 1, which enhances the sealing performance of the device and extends the service life of the device.

[0025] like Figure 1-4As shown, mounting brackets 2 are symmetrically fixed on the outer wall of the housing 1. A guide rod 3 is fixedly installed in the inner cavity of the mounting bracket 2. A mounting block 4 is slidably installed on the surface of the guide rod 3. A locking bolt 6 is threaded on the upper surface of the mounting block 4. A moving groove 5 is opened on the upper surface of the mounting bracket 2 to facilitate the horizontal movement of the locking bolt 6. When the housing 1 needs to be installed on a horizontal plane, simply connect the telescopic support rod to the mounting block 4 by threading. By adjusting the height of the telescopic support rod and the position of the mounting block 4 on the guide rod 3, and by tightening the locking bolt 6 to limit the mounting block 4, the housing 1 is adjusted to a horizontal position, ensuring the safe and stable operation of the equipment.

[0026] Working principle: During installation and use, the instrument body 17 is slidably installed into the inner cavity of the housing 1 along the slider 16. As the instrument body 17 enters the inner cavity of the housing 1, it drives the limiting plate 21 to slide along the fixed rod 19 and compress the return spring 23. After the instrument body 17 is installed, the return spring 23 rebounds, causing the limiting plate 21 to quickly return to its original position, limiting the instrument body 17. This makes the installation of the instrument body 17 more convenient, efficient, and stable, reducing the installation error rate. When sealing the instrument body 17 installed in the housing 1, the insert rod 10 is aligned and inserted into the insertion hole 13, at which point the silicone sealing ring 11 is inserted. In the first sealing cavity 14, the fluororubber sealing ring 12 is inserted into the second sealing cavity 15. Under the magnetic attraction between the first magnet 7 and the second magnet 9, the cover plate 8 seals the housing 1, enhancing the sealing performance of the device and extending its service life. When the housing 1 needs to be installed on a horizontal plane, simply connect the telescopic support rod to the mounting block 4 by thread. By adjusting the height of the telescopic support rod and the position of the mounting block 4 on the guide rod 3, and by tightening the locking bolt 6 to limit the mounting block 4, the housing 1 is adjusted to a horizontal position, ensuring the safe and stable operation of the equipment. This method is suitable for large-scale promotion.
