[0003] Existing master control cabinets usually set a display device on the cabinet door, and the ordinary cabinet door does not have a protection device, so that the display screen is easily broken by external impact, resulting in the scrapping of the display screen and wasting resources. Moreover, when the cabinet door is opened, the display device is no longer within the worker's field of vision, which is not convenient for the worker master to control while observing the equipment status, thus affecting the working efficiency of the equipment. Therefore, it is necessary to develop a master control cabinet. Content of the Utility Model

[0028] Please refer to Figures 1 - 6 , which shows a schematic structural diagram of an implementation manner of a master control cabinet of the present utility model. Please refer to Figures 1 - 6 for a detailed introduction to a master control cabinet.

[0029] A master control cabinet includes a cabinet body 100. A cabinet door 110 is hinged to the front side of the cabinet body 100 through a hinge. Installation openings 120 are opened on the front and rear side walls of the cabinet door 110. An installation plate 140 is rotatably arranged inside the installation opening 120 through a rotating rod 130. The rotating rod 130 is fixedly connected to the installation plate 140. The upper and lower ends of the rotating rod 130 are rotatably arranged at the centers of the upper and lower walls of the inner cavity of the installation opening 120 through bearing seats. A display screen 150 is arranged on the surface of the installation plate 140;

[0030] A driving and locking assembly 200 for driving the rotating rod 130 to rotate and locking the position of the rotating rod 130 is arranged on the cabinet door 110;

[0031] The driving and locking assembly 200 includes a driving rod 210 rotatably located on the rear side wall of the cabinet door 110. An installation cavity is arranged inside the cabinet door 110. The upper end of the rod body of the rotating rod 130 is rotatably located inside the installation cavity and is provided with a first worm gear 220. The front end of the driving rod 210 is rotatably located inside the installation cavity and is provided with a first worm 230 meshing with the first worm gear 220. A hand wheel 240 is arranged at the rear end of the driving rod 210;

[0032] The lead angle of the first worm 230 is smaller than the equivalent friction angle between the meshing teeth of the first worm gear 220, so that the first worm 230 and the first worm gear 220 have self-locking property, and only the first worm 230 can drive the first worm gear 220, rather than the first worm gear 220 driving the first worm 230. After adjusting the installation plate 140, it is more stable and convenient for the installation plate 140 to drive the display screen 150 to rotate by itself.

[0033] A protection plate 300 for covering the display screen 150 is arranged on the front surface of the cabinet door 110 in a lifting manner. An adjusting assembly for adjusting the height of the protection plate 300 is arranged on the front side wall of the cabinet door 110;

[0034] The adjusting assembly includes mounting brackets 310 disposed on the front sidewall of the cabinet door 110 on both the left and right sides of the mounting opening 120. The right-view cross-section of the mounting bracket 310 is in the shape of a "C". A vertical round rod 320 is rotatably penetrated through the bottom wall of the mounting bracket 310. A vertical screw rod 330 is provided at the upper end of the round rod 320. The upper end of the screw rod 330 is rotatably disposed on the top wall of the inner cavity of the mounting bracket 310 through a bearing seat. The threads of the two screw rods 330 are the same and are screwed through the upper and lower walls of the protection plate 300. Second worm wheels 340 are provided at the lower ends of the two round rods 320. Fixed plates 350 are respectively disposed on the front sidewall of the cabinet door 110 on one side of the two second worm wheels 340. A cross bar 360 is rotatably disposed on the sidewalls of the two fixed plates 350. A second worm 370 meshing with the second worm wheel 340 is provided on the rod body of the cross bar 360. A forward and reverse double-headed motor 380 is disposed on the front sidewall of the cabinet door 110. The two output shafts of the forward and reverse double-headed motor 380 are respectively connected to the ends of the two cross bars 360.

[0035] In the specific use process, when the display screen 150 is not needed, the forward and reverse double-headed motor 380 is started to drive the two cross bars 360 to rotate. Through the second worm 370 and the second worm wheel 340, the round rod 320 drives the screw rod 330 to rotate, so as to adjust the height of the protection plate 300, block the display screen 150, and avoid it being directly exposed to the outside and being broken by an external object impact.

[0036] When the cabinet door 110 is opened and the display screen 150 is needed, after first lowering the height of the protection plate 300, the staff drives the drive rod 210 to rotate through the hand wheel 240, and then through the first worm 230 and the first worm wheel 220, the rotating rod 130 drives the mounting plate 140 to rotate, and the display screen 150 can be rotated to face the side of the cabinet body 100, which is convenient for the staff to view.

[0037] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed by the present invention can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the sake of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
