[0028] See also Figure 1-5 ,The utility model provides a technical solution:
[0029] A pull-out inverter cabinet comprises a cabinet body 1, a mounting plate 2 is movably provided on the inner side of the cabinet body 1, a tray 3 is fixedly provided on the upper side of the mounting plate 2, and two groups of support blocks 4 are fixedly provided on the lower side of the mounting plate 2, two groups of movable grooves 5 for docking with the support blocks 4 are provided on the inner side of the cabinet body 1, a second magnet 20 is fixedly provided on the inner side of the movable groove 5, a magnet 19 docking with the second magnet 20 is fixedly provided on the outer side of the support block 4, a fixing frame 9 is fixedly provided on the upper side of the tray 3, two groups of sliders 11 are movably provided on the inner side of the fixing frame 9, both groups of sliders 11 are movably penetrated through the fixing frame 9 and extend to the outside, and a limiting plate 12 is fixedly provided on the outer side of the slider 11 located on the outer side of the fixing frame 9, the mounting plate 2 can be pulled out of the cabinet body 1 as a whole, thereby further improving the convenience of loading and unloading the inverter.
[0030] Specifically, a connecting block 6 is fixedly provided on the lower side of the mounting plate 2, a T-block 7 is fixedly provided on the lower side of the connecting block 6, and a T-slot 8 for docking with the T-block 7 is provided on the inner side of the cabinet body 1. When the mounting plate 2 is pushed or pulled, the T-block 7 can be driven to slide within the T-slot 8 within a limited position, thereby improving the stability of the mounting plate 2 and ensuring the stability of the inverter.
[0031] Furthermore, a slide bar 10 is fixedly provided inside the fixed frame 9 , and the slide bar 10 movably passes through the two groups of sliders 11 . By providing the slide bar 10 , the slider 11 can be limited so that the slider 11 moves along the slide bar 10 , thereby improving the movement stability of the slider 11 .
[0032] It is worth mentioning that two groups of limit springs 13 are arranged on the inner side of the fixed frame 9, one end of the two groups of limit springs 13 are respectively connected to the two sides of the fixed frame 9, and the other end of the limit spring 13 is connected to the slider 11. The limit spring 13 is initially in an elastic state. The elastic force of the limit spring 13 can drive the limit plate 12 to quickly fit the outside of the inverter, thereby improving the convenience of installation of the inverter.
[0033] It is worth noting that a threaded rod 14 is fixedly provided on the upper side of the slider 11, and the threaded rod 14 movably passes through the fixed frame 9 and extends to the upper side, and a butterfly nut 15 is threadedly sleeved on the outer side of the threaded rod 14 located on the upper side of the fixed frame 9, and a sliding groove 16 for docking with the threaded rod 14 is opened on the upper side of the fixed frame 9. By loosening or tightening the butterfly nut 15, the limit plate 12 can be conveniently adjusted or fixed, thereby improving the flexibility of the use of the limit plate 12 while ensuring the fixing stability of the limit plate 12 to the inverter.
[0034] In addition, multiple groups of anti-slip strips 17 are fixedly arranged on the outer side of the limit plate 12. The multiple groups of anti-slip strips 17 are all made of soft materials. By setting multiple groups of soft anti-slip strips 17, the friction force of the limit plate 12 can be increased, so that the fixing effect of the inverter is better.
[0035] It must be mentioned that a handle 18 is fixedly provided on the outer side of the mounting plate 2. By providing the handle 18, the mounting plate 2 can be easily pushed and pulled, thereby improving the convenience of operation.
[0036] Working principle: first place the inverter into the inner side of the tray 3, then loosen the two sets of butterfly nuts upwards, at this time, the limit spring 13 stretches and drives the slider 11 to slide on the outside of the slide rod 10, and the slider 11 drives the limit plate 12 to move when it slides, so that the two sets of limit plates 12 are tightly fitted to the outside of the inverter, and then the two sets of butterfly nuts 15 are tightened downwards, so that the inverter can be quickly fixed, and then the mounting plate 2 is pushed toward the inside of the cabinet body 1 through the handle 18, and the mounting plate 2 drives the tray 3 and the inverter to move. At this time, the T-block 7 slides within the T-slot 8 until the magnet 1 19 and the magnet 2 20 are magnetically attracted to each other, so that the mounting plate 2 can be fixed to the inside of the cabinet body 1, thereby improving the stability of the inverter. In the later stage, the mounting plate 2 can be pulled outward by force, which is also convenient for repairing the inverter.
