[0032] Example 1

[0033] Reference Figure 1 - Figure 7 A circuit control cabinet for a building automation system includes an electrical control box 1 and a side door 2. The side door 2 is rotatably connected to both ends of the electrical control box 1. An adjustment mechanism for mounting holes is installed on one side of the electrical control box 1. A maintenance-friendly mechanism is installed between the electrical control box 1 and the side door 2.

[0034] The mounting hole adjustment mechanism includes a T-block 3, a mating plate 4, a telescopic head 5, a pressing block 6, a spring 7, a mounting fixing plate 8, fixing holes 9, and mating holes 10. Multiple T-blocks 3 are slidably connected inside one side of the electrical control box 1. Two mating plates 4 are slidably connected inside the T-blocks 3. A telescopic head 5 is fixed to one end of one side of each mating plate 4, and a pressing block 6 is fixed to the other end. A spring 7 is positioned between the two mating plates 4. A mounting fixing plate 8 is fixed to one end of each T-block 3. Fixing holes 9 are provided inside both ends of the mounting fixing plate 8. Multiple mating holes 10 are provided inside the electrical control box 1. The telescopic head 5 and the mating holes 10 are slidably connected. The mounting hole adjustment mechanism is adjusted according to the site installation conditions. When adjusting the position, push the pressing block 6. The pressing block 6 drives the mating plate 4 to move. The two mating plates 4 compress the spring 7. The mating plates 4 drive the telescopic head 5 to slide out of the mating hole 10. Hold the mounting plate 8 and pull it. The mounting plate 8 drives the T-block 3 to slide inside the electrical control box 1. When the position is adjusted to the appropriate position as needed, release the pressing block 6. The spring 7 rebounds, and the telescopic head 5 re-enters the mating hole 10 for adjustment. In this way, by pushing the pressing block 6, the spring 7 can be compressed and contracted, so that the telescopic head 5 and the mating hole 10 slide and engage, and the position of the mounting plate 8 can be moved. The position can be moved and fixed according to the site conditions.

[0035] The electrical control box 1 and the side door 2 are rotatably connected by two first hinges 16, and the box door 18 is rotatably connected to one side of the electrical control box 1 by two second hinges 17; a first handle 19 is fixed to one end of one side of the side door 2, and a second handle 20 is fixed to one end of one side of the box door 18; the setting of the first handle 19 and the second handle 20 makes it convenient and flexible to open and close the side door 2 and the box door 18.

[0036] A locking assembly 21 is provided at one end of the interior of the box door 18; the locking assembly 21 can lock the box door 18, thus protecting the internal components of the electrical control box 1 and preventing them from being accidentally touched by unauthorized personnel and thus being damaged, making it safe and reliable to use.

[0037] A transparent viewing window 22 is fixed inside the door 18; through the transparent viewing window 22, the internal situation of the electrical control box 1 can be clearly seen without opening the door 18, which is conducive to timely grasp of the real situation inside the electrical control box 1, facilitating daily inspections by workers and ensuring operational safety.

[0038] Two fan assemblies 23 are fixed inside one of the side-opening doors 2; the fan assembly 23 can effectively dissipate the heat generated by the internal components of the electrical control box 1, realize the internal and external air circulation, and enable the internal components to operate efficiently for a long time.

[0039] Example 2

[0040] Reference Figure 5 and Figure 6 A circuit control cabinet for a building automation system includes a maintenance mechanism comprising a worm gear 11, a knob 12, a worm wheel 13, a threaded rod 14, and a telescopic column 15. The worm gear 11 is rotatably connected inside the control box 1, with a knob 12 fixed to one end. The worm wheel 13 is meshed externally with the worm gear 11, and a threaded rod 14 is fixed to one end. The telescopic column 15 is threadedly connected to the external end of the threaded rod 14. The telescopic column 15 is slidably connected to the control box 1 and also slidably connected to a side door 2. The worm wheel 13 is rotatably connected to the control box 1. When inspecting and maintaining the circuit control cabinet of the building automation system, Rotating knob 12 causes worm gear 11 to rotate, which in turn drives worm wheel 13 to rotate. Worm wheel 13 then drives threaded rod 14 to rotate, which in turn drives telescopic column 15 to slide inside control box 1. Continuing to rotate knob 12 causes telescopic column 15 to slide into the side door 2. In this way, rotating knob 12, through the meshing transmission of worm gear 11 and worm wheel 13, achieves threaded engagement between threaded rod 14 and telescopic column 15, allowing telescopic column 15 to slide inside side door 2, thus controlling the opening and closing of side door 2. This avoids the problem of limited space during inspection and maintenance, which can hinder workers' movement and reduce maintenance efficiency.

[0041] The usage process of the circuit control cabinet for a building automation system provided by this utility model is as follows:

[0042] When adjusting the position of the mounting holes according to the on-site installation conditions, multiple T-blocks 3 are slidably connected inside one side of the electrical control box 1. Two mating plates 4 are slidably connected inside the T-blocks 3. A telescopic head 5 is fixed to one end of one side of the mating plate 4, and a pressing block 6 is fixed to the other end of one side of the mating plate 4. A spring 7 is installed between the two mating plates 4. A mounting plate 8 is fixed to one end of the T-blocks 3. Fixing holes 9 are opened inside both ends of the mounting plate 8. Multiple mating holes 10 are opened inside the electrical control box 1. The telescopic head 5 is slidably connected to the mating holes 10. This pushes the pressing block 6, which in turn drives the mating... When plate 4 moves, the two mating plates 4 compress the spring 7. The mating plates 4 drive the telescopic head 5 to slide out of the mating hole 10. Hold the mounting plate 8 and pull it. The mounting plate 8 drives the T-block 3 to slide inside the electrical control box 1. When it is adjusted to the appropriate position as needed, release the pressing block 6. The spring 7 rebounds, and the telescopic head 5 re-enters the mating hole 10 for adjustment. In this way, by pushing the pressing block 6, the spring 7 can be compressed and contracted, so that the telescopic head 5 and the mating hole 10 slide and engage, and the position of the mounting plate 8 can be moved. The position can be moved and fixed according to the site conditions.

[0043] When the circuit control cabinet of the building automation system needs to be inspected, the control box 1 has a worm gear 11 internally connected to it. One end of the worm gear 11 is fixed to a knob 12. The worm gear 11 is externally connected to a worm wheel 13, one end of which is fixed to a threaded rod 14. The threaded rod 14 is externally threaded to a telescopic column 15, which is slidably connected to the control box 1 and also slidably connected to the side door 2. The worm wheel 13 is rotatably connected to the control box 1. Rotating the knob 12 causes the worm gear 11 to rotate. The worm gear 13 is driven to rotate, which in turn drives the threaded rod 14 to rotate. The threaded rod 14 drives the telescopic column 15 to slide inside the control box 1. By continuing to rotate the knob 12, the telescopic column 15 slides into the side door 2. In this way, by rotating the knob 12, the threaded engagement between the threaded rod 14 and the telescopic column 15 is achieved through the meshing transmission of the worm gear 11 and the worm wheel 13, so that the telescopic column 15 slides inside the side door 2, thereby controlling the opening and closing of the side door 2. This avoids the problem of insufficient space for workers to stretch out during inspection and maintenance, which affects maintenance efficiency.
