[0029] Example 2

[0030] Please refer to Figure 6-7, the present embodiment provides an open-type cable bottom quick plugging device. When the cabinet is not a metal iron plate, it cannot be fixed by the magnet 15, so the fixing structure is improved. Specifically, the upper left ring part 8 integrally extends a flange cover 16, and the flange cover 16 is a circle of protruding rings. The amount of protrusion depends on the aperture size of the sealed hole on the electrical equipment mounting plate 11. A plurality of mounting holes 17 are provided on the flange cover 16. The fixing is achieved by connecting the electrical equipment mounting plate 11 with bolts.

[0031] It should be noted that these two different implementations can also be used simultaneously, that is, while the upper ring portion is fixed by the magnet 15, a flange cover 16 is extended from the outer edge of the upper ring portion and fixed by bolts.

[0032] The present embodiment provides an open-type cable bottom quick sealing device, which are connected as follows: the upper left ring portion 8 and the lower left ring portion 10 are connected and fixed by a tight fit through a fixing pin 9, and the upper right ring portion 12 and the lower right ring portion 13 are also connected and fixed by a tight fit through a fixing pin 9; the left component 4 and the right component 5 are rotatably connected and fixed by a clearance fit of a rotating pin 6; the magnet 15 is magnetically fixed by a stepped cavity.

[0033] The present embodiment provides an open-type cable bottom quick plugging device. In normal use, the fire protection cover 2 is crimped between the upper ring part and the lower ring part, and the upper ring part and the lower ring part are tightly matched and fixed with the fixing pin 9, and the rotating pin 6 is installed to unfold the fixing component 1, and after the cable 19 is inserted, the fixing component 1 is closed and locked with the positioning pin 7. Under the fire protection cover 2, the permanent coil spring 3 is inserted to achieve overall sealing.

[0034] The beneficial effects of the utility model are as follows: since the electrical equipment installation plate 11 (cabinet) is basically an iron plate, it can be quickly installed on one side of the cabinet by adopting a magnetic attraction or bolt fixing method. The fixing assembly 1 adopts an open type, and the cable adopts a sleeve-type structure, which is easy to operate, solves the sealing problem, and can quickly block the installed cables, and can be blocked with power on, and can be used universally for different cable cross-sections. At the same time, it can also be used as a way to block some holes that have fire protection requirements.
