When the cabinet is used, the second driving member 440 is started, the output shaft of the second driving member 440 rotates to drive the threaded rod 450 to rotate, so that the third threaded sleeve 460 drives the sliding block 420 and the bearing frame 430 above the sliding block to slide towards the outside of the cabinet 110 through the second fixing rod 470, and the space between the back of the equipment and the inner wall of the cabinet 110 is enlarged; by adopting the scheme, the space between the back of the equipment and the inner wall of the cabinet body 110 can be enlarged in an outward sliding mode of the equipment, so that the assembly 200 is unfolded in a matching manner, a maintainer can operate the back of the equipment conveniently from the side part of the cabinet body 110, the situation that the maintainer mistakenly touches other equipment assemblies in the maintenance process is effectively prevented, and the maintenance efficiency is improved.
Specifically, this be convenient for maintenance's switch board's theory of operation: during maintenance, the cabinet door 140 is opened, then the first driving member 210 is started, the first driving member 210 drives the bidirectional screw rod 220 to rotate through the bevel gear transmission member 230, so that the first threaded sleeve 240 and the second threaded sleeve 250 are far away from each other, the first threaded sleeve 240 drives the first side plate 120 to rotate and open through the first connecting rod 260, the second threaded sleeve 250 drives the second side plate 130 to rotate and open through the second connecting rod 270, the cabinet door 140 is separated from the cabinet body 110 along with the first side plate 120, at this time, a maintainer can maintain the equipment from both sides of the cabinet body 110, during the opening process of the first side plate 120 and the second side plate 130, the first threaded sleeve 240 and the second threaded sleeve 250 also drive the second rainproof plate 320 to rotate through the elastic expansion member 330, the first fixing rod 340 and the third connecting rod 350, thereby enlarge protection domain, thereby stop the sleet of whereabouts, prevent that the sleet from wafting into cabinet body 110 inner chamber and damaging equipment, when needs are changed equipment or are carried out the plug to the back cable, start second driving piece 440, second driving piece 440 output shaft rotates and drives threaded rod 450 and rotate, make third thread bush 460 drive the slider 420 and the bearing frame 430 of top through second dead lever 470 and slide towards the cabinet body 110 is outer, enlarge the space between equipment back and the cabinet body 110 inner wall, make things convenient for the maintainer to operate the equipment back from cabinet body 110 lateral part, the condition that the maintainer touched other equipment assembly in the maintenance in-process mistake has effectively been prevented and has been taken place, maintenance efficiency has been promoted.
It should be noted that the specific model specifications of the first driving element 210 and the second driving element 440 need to be determined by type selection according to the actual specification of the device, and the specific type selection calculation method adopts the prior art, so detailed description is omitted.
The power supply of the first driving member 210 and the second driving member 440 and the principle thereof will be apparent to those skilled in the art and will not be described in detail herein.
The above description is only an example of the present application and is not intended to limit the scope of the present application, and various modifications and changes may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
