[0019] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0020] like Figures 1 to 5As shown, this embodiment discloses a weak current control cabinet, which includes a cabinet body 8 and an inclined body 5. The inclined body 5 is arranged at the upper end of the cabinet body 8, and the width of the inclined body 5 exceeds the width of the cabinet body 8. Wind ducts 2 are provided on both sides of the inclined body 5. The wind ducts 2 are connected to the inside of the cabinet body 8. A ventilation plate 15 is provided between the wind ducts 2. The ventilation plate 15 has a plurality of ventilation holes 9, and the ventilation plate 15 is hinged to the rear end of the inclined body 5. A cover plate 1 is provided on the upper end of the ventilation plate 15, and the cover plate 1 is also hinged to the rear end of the inclined body 5. Hinge; a fixing block 10 is provided at the front end portion inside the inner side of the cover plate 1, a connecting ring 11 is fixed on the fixing block 10, a hydraulic rod 4 is provided at the corresponding position of the air trough 2 and the connecting ring 11, a locking ring 3 is provided at the upper end of the hydraulic rod 4, the locking ring 3 has an opening, and the opening is used to connect with the connecting ring 11, a temperature sensor is provided in the cabinet 8, the temperature sensor is connected to a controller, and the controller is also connected to the hydraulic rod 4, for controlling the lifting of the hydraulic rod 4 by the temperature in the cabinet 8 to adjust the opening and closing angle of the cover plate 1.
