[0020] The present invention is described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 3-8 ,

[0022] An electrical distribution cabinet comprises a cabinet body 101 and a drawer frame 201, wherein the drawer frame 201 is slidably connected to the cabinet body 101 through a limiting mechanism, a rotating frame 401 is rotatably connected to the drawer frame 201 through a bearing, one end of the rotating frame 401 is fixedly connected to a contact rod 402 through bolts, and the other end of the rotating frame 401 is fixedly connected to an operating rod 403 through bolts, a fixing plate 301 is welded to one end of the drawer frame 201 through bolts, two first through grooves 304 are formed on the fixing plate 301, a control panel 305 is welded to the other end of the drawer frame 201 through bolts, and two second through grooves 306 are formed on the control panel 305, the rotating frame 401 slides through the two first through grooves 304 and the two second through grooves 306, a plug 303 is fixedly connected to the fixing plate 301, a connecting line 302 is fixedly connected to the plug 303, a socket 103 is fixedly connected to the inside of the cabinet body 101, and the socket 103 is connected to a power supply.

[0023] When using the electrical distribution cabinet, the staff installs the required electronic equipment in the drawer rack 201, and then connects the connecting wire 302 on the plug 303 to the electronic equipment, so as to facilitate power supply to the electronic equipment. The drawer rack 201 is slid into the cabinet 101 through the cooperation of the limiting mechanism, so that the drawer rack 201 is located inside the cabinet 101, thereby hiding the electronic equipment. When the drawer rack 201 enters the cabinet 101, the plug 303 is inserted into the socket 103, thereby realizing the function of powering the electronic equipment.

[0024] When the electronic equipment needs to be repaired, the staff pulls the drawer rack 201 outward, so that the drawer rack 201 is separated from the cabinet 101, and the plug 303 is separated from the socket 103, thereby realizing the automatic power-off function to ensure the safety of the staff. Compared with conventional distribution cabinets, this device is more convenient for staff to repair electronic equipment, solves the problem of limited operation in a small space, and solves the problem of forgetting to turn off the power and affecting safety.

[0025] Since the rotating frame 401 is rotatably connected to the drawer frame 201, when the drawer frame 201 enters the cabinet 101, the staff pulls down the operating rod 403 to rotate the rotating frame 401, so that the contact rod 402 moves upward, and the plug 303 can be inserted into the socket 103. When the rotating frame 401 is in a horizontal state, the contact rod 402 will block the plug 303, making it impossible for the plug 303 to be inserted into the socket 103. The above-mentioned structural design can prevent non-professionals from illegally operating the distribution cabinet, thereby further ensuring the safety of equipment and personnel.

[0026] See also Figure 3-4 ,

[0027] The limiting mechanism includes two slide bars 102 and two slide grooves 203 . The two slide bars 102 are respectively fixedly connected to the inner walls at the left and right ends of the cabinet 101 . The two slide grooves 203 are respectively opened at the left and right ends of the drawer frame 201 .

[0028] The slide bar 102 cooperates with the slide groove 203 to achieve a sliding connection, thereby realizing the function of the drawer frame 201 sliding in the cabinet body 101.

[0029] See also Figure 3 ,

[0030] A guide block 104 is fixedly connected to the inner wall of the cabinet 101 by bolts, and an arc surface is provided on the guide block 104 .

[0031] The guide block 104 serves to facilitate the operation of the rotating frame 401. When the drawer frame 201 needs to be separated from the cabinet 101, the staff pulls the operating rod 403 upwards, the rotating frame 401 rotates and the contact rod 402 moves downward. The contact rod 402 can move downward along the arc surface on the guide block 104, so that the drawer frame 201 moves outward a certain distance. When the contact rod 402 separates from the guide block 104, the plug 303 completely separates from the socket 103, realizing the power-off function. Then the staff can slowly pull the drawer frame 201 outward. The above structure eliminates the need for the staff to pull the drawer frame 201 outward with brute force, thereby avoiding the inertia force causing the drawer frame 201 to fall out of the staff's hands and avoid the risk of damaging the electronic equipment.

[0032] See also Figure 3 and Figure 5 ,

[0033] An arc rod 404 is welded and fixedly connected to the lower end of the rotating frame 401 , and a slot plate 105 is welded and fixedly connected to the lower end of the cabinet body 101 , and a slot is formed on the slot plate 105 .

[0034] When the drawer rack 201 is inserted into the cabinet 101, the staff pulls down the operating rod 403 to insert the arc rod 404 into the groove of the groove plate 105. Since the arc rod 404 is arc-shaped, as the arc rod 404 moves downward, the drawer rack 201 gradually approaches the inner wall of the cabinet 101, thereby ensuring that the plug 303 is close to the socket 103 to prevent the two from being separated.

[0035] See also Figure 1 ,

[0036] A plurality of positioning holes 405 are provided on the arc rod 404. When the position of the arc rod 404 is determined, the staff inserts a lock into the corresponding positioning hole 405 to fix the arc rod 404, thereby preventing non-staff from operating the operating rod 403 and ensuring the safety of the electronic equipment.

[0037] See also Figure 4 ,

[0038] The surface of the contact rod 402 is covered with insulating rubber, which plays an insulating role to prevent the staff from getting electric shock when operating the rotating frame 401, and at the same time can reduce the wear caused by the contact rod 402 and the guide block 104 when they contact.

[0039] See also Figure 5 ,

[0040] A display screen and adjustment buttons are installed on the control panel 305, and both the display screen and the adjustment buttons are connected to the host computer.

[0041] The display screen and adjustment buttons make it easy for the staff to observe the working data of the electronic equipment from the outside and to control the electronic equipment.

[0042] See also Figure 5 ,

[0043] A plurality of mounting holes 202 are provided at the bottom of the drawer frame 201 . By inserting bolts into the plurality of mounting holes 202 , the electronic device can be fixed to the bottom of the drawer frame 201 .

[0044] See also Figure 3 ,

[0045] A buffer rubber is fixed on the surface of the socket 103 , which has a buffering effect and further makes the plug 303 close to the socket 103 .

[0046] See also Figure 3 ,

[0047] The thickness of the bottom of the guide block 104 is greater than the thickness of the socket 103 . When the contact rod 402 moves downward to separate from the guide block 104 , the contact rod 402 will not collide with the socket 103 , thereby preventing the socket 103 from being worn.
