[0047] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0048] As Figure 1-2, as shown in Fig. 8, a GGD type low-voltage AC power distribution cabinet includes: a cabinet body 100, provided with a space for installing electrical equipment; a frame body 300, rotatably connected to the cabinet body 100 at one side; a connecting roller 400, rotatably connected to the frame body 300; a cabinet door 200, arranged on the connecting roller 400; a buffer member 302, arranged on the frame body 300; wherein, a first connecting groove for connecting the cabinet door 200 is arranged on the connecting roller 400, and a fixing member 404 for fixing the cabinet door 200 in the first connecting groove is arranged in the first connecting groove. When the connecting roller 400 rotates to a specified angle, the cabinet door 200 is removed from the first connecting groove; the cabinet door 200 is made of a sheet metal part, the frame body 300 is in an I shape, a first connecting rod 402 is arranged on the side wall of the frame body 300, and the first connecting rod 402 is connected to the cabinet body 100 through a hinge. The frame body 300 is rotatably connected to the cabinet body 100 through the first connecting rod 402; the buffer member 302 is a spring arranged on the frame body 300; the cabinet door 200 is inserted into the first connecting groove in a plugging manner, the top of the cabinet door 200 is inserted into the first connecting groove, and the fixing member 404 fixes the cabinet door 200 in the first connecting groove to ensure the connection effect between the cabinet door 200 and the frame body 300; when the cabinet door 200 is damaged and needs to be replaced, pull the bottom end of the cabinet door 200, the cabinet door 200 drives the connecting roller 400 to rotate, and after the connecting roller 400 rotates to a set angle, the cabinet door 200 is removed from the first connecting groove so as to replace the cabinet door 200; the cabinet door 200 can only be removed from the first connecting groove after the connecting roller 400 rotates to a specified angle, which ensures the reliability of the connection between the cabinet door 200 and the frame body 300, avoids the cabinet door 200 falling out of the first connecting groove during the use of the power distribution cabinet, and also avoids removing the cabinet door 200 from the connecting roller 400 during misoperation; only by rotating the cabinet door 200 by a specified angle can the cabinet door 200 be removed, without the need to turn screws, making the disassembly operation of the cabinet door 200 more convenient; the buffer member 302 provides a supporting force for the middle part of the cabinet door 200, and at the same time increases the impact resistance of the cabinet door 200, absorbs a part of the force hitting the cabinet door 200, and plays a protective role for the cabinet door 200.

[0049] The connecting roller 400 rotates outwards relative to the cabinet body 100; when disassembling the cabinet door 200, pull the bottom end of the cabinet door 200 in a direction away from the cabinet body 100, and the cabinet door 200 drives the connecting roller 400 to rotate to a specified angle to remove the cabinet door 200 from the first connecting groove; by pulling the bottom end of the cabinet door 200 to rotate outwards, the distance between the operator and the power distribution cabinet is increased, avoiding the harm caused by the discharge of the power distribution cabinet to the operator.

[0050] The GGD type low-voltage AC power distribution cabinet further includes: a connecting plate 202, which is arranged at the bottom of the cabinet door 200. The connecting plate 202 is a bent part at the bottom of the cabinet door 200 and is perpendicular to the cabinet door 200; a fixing device for fixing the connecting plate 202 on the frame body 300; an installation groove for installing the fixing device is provided on the frame body 300; after the top end of the cabinet door 200 is inserted into the first connecting groove and the cabinet door 200 is rotated to the vertical state, the fixing device fixes the connecting plate 202, and the fixing device is used to fix the bottom of the cabinet door 200, so that the cabinet door 200 cannot rotate, improving the connection effect between the cabinet door 200 and the frame body 300 and increasing the stability of the power distribution cabinet during use.

[0051] As Figure 4-5 shown, the fixing device includes: an installation block 307 arranged in the installation groove; a first reset switch 308 arranged on the installation block 307; a plug rod 203 arranged at the bottom of the first reset switch 308; a groove body is provided on the installation block 307, a first through groove is provided at the bottom of the groove body, a slot is provided on the connecting plate 202, and the plug rod 203 is inserted into the first through groove; the first reset switch 308 has the same structure as the reset button switch on the market, that is, the first reset switch 308 will be fixed at the corresponding position in the groove body when pressed for the first time and will protrude from the groove body when pressed for the second time; a second connecting rod 204 is hinged at the bottom of the first reset switch 308, and the other end of the second connecting rod 204 is hinged to the plug rod 203; the first reset switch 308 protrudes from the frame body 300; after the cabinet door 200 is flipped to the vertical state, the cabinet door 200 is pushed towards the frame body 300. The cabinet door 200 pushes the first reset switch 308 to move. The movement of the first reset switch 308 drives the second connecting rod 204 to rotate. The second connecting rod 204 pushes the plug rod 203 to move downward. The plug rod 203 is inserted into the slot to fix the connecting plate 202, and the cabinet door 200 is fixed by the cooperation of the plug rod 203 and the slot; when disassembling the cabinet door 200, the cabinet door 200 is pushed towards the frame body 300, and the cabinet door 200 pushes the first reset switch 308 to move again. The first reset switch 308 moves outward to drive the second connecting rod 204 to rotate. The second connecting rod 204 pulls the plug rod 203 to move upward. The plug rod 203 disengages from the slot, releasing the fixation of the cabinet door 200, and the cabinet door 200 is flipped outward to remove the cabinet door 200 from the connecting roller 400.

[0052] The mounting block 307 is provided with a second support spring 306. The cross-section of the first through groove is much larger than that of the insertion rod 203. The elastic force of the second support spring 306 is less than that of the first reset switch 308. When the cabinet door 200 pushes the first reset switch 308 to move, the mounting block 307 first compresses the second support spring 306. After the second support spring 306 cannot contract, it then pushes the first reset switch 308 to move relative to the mounting block 307 to complete the fixation of the bottom of the cabinet door 200. The cross-sectional area of the first through groove is set large so that the insertion rod 203 can move within the first through groove, providing a moving space for the cabinet door 200 after being impacted and absorbing part of the impact on the cabinet door 200. The elastic force of the second support spring 306 is set small to prevent the insertion rod 203 from directly disengaging from the slot after the cabinet door 200 is impacted, enabling the cabinet door 200 to have a certain bearing capacity and ensuring the fixing effect of the fixing device on the cabinet door 200.

[0053] The frame body 300 is provided with a groove. After the cabinet door 200 is installed, the connecting plate 202 is opposite to the groove position.
