The threaded driving and evenly blowing component is used for driving the corresponding two movable electrical appliance mounting plates 5 to move up and down for adjustment, achieving the effect of conveniently adjusting the distance from the fixed electrical appliance mounting plate 4 according to the size of the electrical appliance to be installed. The support sleeve 11 is used to ensure the internal connection of the two threaded driving and evenly blowing components. The threaded driving and evenly blowing component is also used for evenly blowing and cooling the inside of the outgoing line cabinet body 1 when air enters the inside;

[0026] The top of the outgoing line cabinet body 1 is provided with a temperature control and air supply component. The bottom end of the temperature control and air supply component extends into the upper threaded driving and evenly blowing component. A temperature sensor 3 electrically connected to the temperature control and air supply component is fixedly installed on the left inner wall of the outgoing line cabinet body 1.

The blower 16 supplies air into the upper external threaded sleeve 9 through the conical cover 15.

[0030] The usage method of this embodiment is as follows: When in use, the static electrical appliance mounting plate 4 and the moving electrical appliance mounting plate 5 are used to enable personnel to perform multi-layer installation and fixation of multiple electrical appliances. When it is necessary to adjust the distance between the upper or lower moving electrical appliance mounting plate 5 and the static electrical appliance mounting plate 4 according to the size of the electrical appliance, rotate the corresponding handle rod 13 forward to drive the external thread sleeve 9 to rotate. The rotation of the external thread sleeve 9 drives the corresponding internal thread sleeve 10 to move upward or downward. The internal thread sleeve 10 drives the corresponding two moving electrical appliance mounting plates 5 to move upward or downward for adjustment. The moving electrical appliance mounting plate 5 drives the corresponding slider 8 to slide vertically on the vertical guide rod 7. At this time, the distance between the moving electrical appliance mounting plate 5 and the corresponding static electrical appliance mounting plate 4 changes. After adjustment to the appropriate position, stop rotating the handle rod 13. At this time, under the self-thread damping locking force of the external thread sleeve 9 and the corresponding internal thread sleeve 10, the adjusted fixation is achieved. By means of the adjustable distance between the upper or lower moving electrical appliance mounting plate 5 and the static electrical appliance mounting plate 4, and with the adjustment parts all located in the middle position inside, instead of setting holes that penetrate the outside of the wire outlet cabinet body 1 on both sides, the phenomenon of a large amount of external dust entering or water splashing in can be avoided, achieving the effect of flexibly adjusting the internal installation space size while ensuring safe and stable use, and improving the use safety and stability;

[0031] The temperature sensor 3 is used to continuously monitor the temperature inside the wire outlet cabinet body 1 and transmit the temperature value to the temperature controller 2. When the temperature value exceeds the preset value, the temperature controller 2 controls the fan 16 to start. The fan 16 supplies air into the upper external thread sleeve 9 through the conical cover 15. The air inside the upper external thread sleeve 9 enters the lower external thread sleeve 9 through the support sleeve 11, and then the air is evenly blown out through the multiple air blowing holes 14 on the external thread sleeve 9 to perform heat dissipation work on the inside of the wire outlet cabinet body 1. By arranging the external thread sleeve 9 in the middle and vertically, and with multiple air blowing holes 14 arranged vertically on its four sides, the inside of the wire outlet cabinet body 1 can be evenly blown from the middle to the four sides, thereby improving the uniformity of air blowing and heat dissipation and ensuring uniform and stable heat dissipation work. The hot air inside the wire outlet cabinet body 1 is discharged outward through the multiple downwardly inclined heat dissipation holes 102; when the temperature drops below the preset value, the temperature controller 2 controls the fan 16 to automatically turn off.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
