[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] The present utility model provides a technical solution: as Figure 1 - Figure 5As shown in the figure, in this embodiment, a modular low-voltage distribution box includes a box body 1. Inside the box body 1, there is a first mounting rack 7. One side of the first mounting rack 7 is fixedly connected to a mounting box 9. One side of the mounting box 9 is provided with a mounting groove 24. The inner wall of the mounting groove 24 is slidably connected to a pressing frame 27. One side of the pressing frame 27 is fixedly connected to a push rod 28. The inner wall of the mounting box 9 is slidably connected to a sliding frame 25. One end of the sliding frame 25 is fixedly connected to a special-shaped slider 29. One side of the special-shaped slider 29 is slidably connected to one end of the push rod 28. The outer wall of the sliding frame 25 is sleeved with a second return spring 26. One end of the second return spring 26 is fixedly connected to one side of the inner wall of the mounting box 9. One side of the special-shaped slider 29 is movably clamped with a T-shaped fixing block 19. One side of the T-shaped fixing block 19 is fixedly connected to an electronic component 18. By pressing the pressing frame 27, one end of the push rod 28 slides along the surface of the special-shaped slider 29, pushing the special-shaped slider 29 outward. The special-shaped slider 29 releases the restriction on the T-shaped fixing block 19, so that the electronic component 18 can be taken out of the mounting box 9. During installation, just press the electronic component 18 into the mounting box 9, making the special-shaped slider 29 squeeze outward. When the T-shaped fixing block 19 completely enters the mounting box 9, the reaction force of the second return spring 26 limits the special-shaped slider 29 to the T-shaped fixing block 19, thus fixing the electronic component 18. The cooperation between the T-shaped fixing block 19 and the push rod 28 can quickly install and disassemble electrical components, with simple operation and improved maintenance efficiency of electrical components in the distribution box. There are four special-shaped sliders 29 installed in the mounting box 9, and each of them has the same structure.

[0024] As Figure 5 shown, one side of the upper end of the mounting box 9 is fixedly connected to a plurality of first return springs 23. One end of the plurality of first return springs 23 is fixedly connected to one side of the pressing frame 27. Through the first return springs 23, the pressing frame 27 can be quickly ejected, preventing the push rod 28 from pressing on the special-shaped slider 29 and affecting the fixing of the special-shaped slider 29 to the T-shaped fixing block 19.

[0025] As Figure 1 and Figure 2 shown, one side of the box body 1 is penetrated with heat dissipation holes 2. Both sides of the inner wall of the box body 1 are fixedly connected to mounting frames 11. The inner wall of the mounting frames 11 is slidably clamped with filter nets 12. Through the cooperation between the filter nets 12 and the mounting frames 11, the dust on the filter nets 12 can be cleaned, improving the heat dissipation efficiency of the box body 1.

[0026] As Figure 2 shown, a T-shaped sliding groove 6 is opened at the bottom inside the box body 1. The inner wall of the T-shaped sliding groove 6 is slidably connected to a T-shaped sliding block 5. One side of the T-shaped sliding block 5 is fixedly connected to a sliding seat 4. The upper end of the sliding seat 4 is fixedly connected to one side of the first mounting rack 7. Through the cooperation between the T-shaped sliding groove 6 and the T-shaped sliding block 5, the stability of the sliding seat 4 is improved.

[0027] AsFigure 2 and Figure 3 As shown, a sliding rod 15 is fixedly connected to the upper end of the sliding seat 4, and the outer side wall of the sliding rod 15 is slidably connected to two mounting frames 8, and sliding columns 10 are fixedly connected to both sides of the mounting frames 8. Special-shaped sliding grooves 3 are provided on both sides of the inner wall of the box body 1, and the inner wall of the special-shaped sliding groove 3 is slidably connected to the outer side wall of the sliding column 10. A connecting block 13 is fixedly connected to one side of the inner wall of the box body 1, and a threaded rod 14 is rotatably connected to the inner wall of the connecting block 13. One side of the outer side wall of the threaded rod 14 is threadedly connected to one side of the mounting frame 7. By rotating the threaded rod 14, the threaded rod 2 16 and the threaded rod 14 drive the sliding seat 4 to slide in the T-shaped slide groove 6. During the movement, the sliding columns 10 on the two mounting frames 2 8 slide in the special-shaped slide groove 3. When reaching the corner of the special-shaped slide groove 3, the mounting frame 1 7 and the two mounting frames 2 8 slowly slide and unfold on the sliding rod 15, which is convenient for the staff to check the electronic components 18 on the mounting frame 1 7 and the two mounting frames 2 8, and prevent the small distance between the upper and lower electronic components 18 from affecting the staff's inspection of the circuit.

[0028] like Figure 4 As shown, a fixing ring 22 is fixedly connected to one side of the connecting block 13, and a hexagonal rotating rod 20 is fixedly connected to one end of the threaded rod 14. A hexagonal sliding ring 21 is slidably connected to one side of the outer wall of the hexagonal rotating rod 20. One side of the hexagonal sliding ring 21 is clamped with the inner wall of the fixing ring 22. The hexagonal sliding ring 21 is pushed and clamped in the fixing ring 22, thereby fixing the hexagonal rotating rod 20 on the connecting block 13 to prevent the two mounting frames 28 from sliding down along the slope of the special-shaped slide groove 3 during inspection. When the hexagonal sliding ring 21 is clamped in the fixing ring 22, one side of the inner wall of the hexagonal sliding ring 21 is on the outer wall of the hexagonal rotating rod 20.

[0029] like Figure 3 As shown, one end of the threaded rod 14 is transmission-connected with a transmission rod 17, one end of the transmission rod 17 is transmission-connected with a threaded rod 2 16, one side of the outer wall of the threaded rod 2 16 is transmission-connected with the other side of the mounting frame 1 7, and through the structural design of the transmission rod 17, the transmission rod 17 can drive the threaded rod 2 16 to rotate while the threaded rod 14 is rotated, so that both sides of the sliding seat 4 are pushed at the same time.

[0030] The utility model provides a modular low-voltage distribution box, and the specific working principle is as follows:

[0031] When installing the electronic component 18 on the distribution box, press the electronic component 18 into the installation box 9. The T-shaped fixing block 19 squeezes the special-shaped slider 29 outwards. When the T-shaped fixing block 19 completely enters the installation box 9, the reaction force of the second reset spring 26 limits the special-shaped slider 29 to the T-shaped fixing block 19, thereby fixing and installing the electronic component 18. After using it for a period of time, when inspection is required, pull the hexagonal sliding ring 21. When sliding the hexagonal sliding ring 21 out of the fixing ring 22, rotate the hexagonal rotating rod 20 so that the second threaded rod 16 and the first threaded rod 14 drive the sliding seat 4 to slide in the T-shaped sliding groove 6. During the movement, the sliding columns 10 on the two second mounting frames 8 slide in the special-shaped sliding groove 3. When reaching the corner of the special-shaped sliding groove 3, the first mounting frame 7 and the two second mounting frames 8 slowly slide and unfold on the sliding rod 15. At the unfolded top, push the hexagonal sliding ring 21 and lock the hexagonal sliding ring 21 in the fixing ring 22 to make the connecting block 13 restrict the rotation of the hexagonal rotating rod 20. The staff observes the electronic components 18 on the first mounting frame 7 and the two second mounting frames 8. When detecting a damaged electronic component 18, press the pressing frame 27 so that one end of the ejector rod 28 slides along the surface of the special-shaped slider 29, push the special-shaped slider 29 outwards, and the special-shaped slider 29 releases the restriction on the T-shaped fixing block 19, and then take out the electronic component 18 from the installation box 9.
