When the connecting block 37 moves to the outside of the distribution room, the limit block 372 is still located in the distribution room, thereby achieving the purpose of limiting the connecting block 37 and fixing the connecting block 37. When the connecting block 37 moves to the end of the slide rail 373, the connecting block 37 will move to the support plate 375 and contact the induction switch, so that the induction switch sends an opening signal. At this time, the state of the support plate 375 is adjusted from the self-locking state to the sliding state, and then the support plate 375 will drive the connecting block 37 to move outward, so that the connecting block 37 moves to the outside of the distribution room.

[0039] And a supporting and protecting component 4 , wherein the supporting and protecting component 4 is arranged in the power distribution room, and the supporting and protecting component 4 is used to provide support for the power distribution drawer 2 .

[0041] Specifically, when the distribution drawer 2 is pulled out, the support rod 41 will be driven to move synchronously. Therefore, an anti-slip pad or other structure for increasing friction can be added between the support rod 41 and the distribution drawer 2, or a synchronously movable and detachable structure can be set between the support rod 41 and the distribution drawer 2; after the distribution drawer 2 is pulled out, the support rod 41 will also be pulled out, and the support rod 41 is located at the bottom of the distribution drawer 2, so it can provide support for the distribution drawer 2, thereby achieving the purpose of protecting the normal use of the distribution drawer 2 and improving the stability of the distribution drawer 2 during use.

[0042] In a preferred embodiment, the support and protection assembly 4 also includes a cross bar 42, one end of the support bar 41 extends to the outside of the power distribution drawer 2, and the cross bar 42 is connected to one end of the support bar 41 by bolts, and two adjacent support rods 41 are connected to the same cross bar 42.

[0043] Specifically, the cross bar 42 and the support bar 41 can be fixed or disassembled by bolts.

[0044] In a preferred embodiment, the support and protection assembly 4 further includes a second connection block 43, one end of the support rod 41 is connected to the second connection block 43 via a rotating shaft 3 44, the second connection block 43 is slidably connected to the partition 11 via a slide rail 3 45, a second support plate 46 is provided inside the partition 11 and is slidably connected to the end of the slide rail 3 45, and a second induction switch is provided on the second support plate 46. The first and second induction switches can be selected to use gravity sensor switches, or other mechanical structures that can be unlocked or locked after receiving a signal, when unlocking, the first and second support plates can be moved, and when locked, the positions of the first and second support plates are fixed.

When the connecting block 2 43 moves to the end of the slide rail 3 45 and continues to move to the support plate 2 46, until the connecting block 2 43 contacts the induction switch 2, at which time the induction switch sends a signal to release the fixation, so that the support plate 2 46 is adjusted from the locked state to the sliding state. At this time, the support plate 2 46 will drive the connecting block 2 43 to move outward, so that the connecting block 2 43 moves to the outside of the distribution room.

[0046] In a preferred embodiment, the support and protection assembly 4 also includes a second limit block 47, and the second limit block 47 is connected to the second connection block 43 through a second connection rod, and the second limit block 47 is slidably connected to the partition 11 through a fourth slide rail 48.

[0047] Specifically, when the connecting block 43 moves, it will drive the limit block 47 to move synchronously through the connecting rod 2. When the connecting block 43 moves to the outside of the distribution room, the limit block 47 is still located in the distribution room, thereby achieving the purpose of the limit block 47 limiting the connecting block 43.

[0049] The working principle of the present invention is as follows: when in use, the power distribution drawer 2 can be pulled out by the handle, and the power distribution drawer 2 can be pulled out to debug the electrical appliances carried therein. If two adjacent or close power distribution drawers 2 in a vertical direction are pulled out for use at the same time, the angle of the power distribution drawer 2 can be adjusted at this time. The process of angle adjustment is as follows: one side of the power distribution drawer 2 is marked as the open side, and the other side is marked as the closed side. The knob 353 at the open side is controlled to drive the second shaft 352 to rotate, and the second shaft 352 will drive the double-sided gear through the second gear 351. The double-sided rack 34 moves, so that the double-sided rack 34 drives the gear 1 33 to rotate, and the gear 1 33 drives the sleeve 31 to rotate, and the direction of the opening 32 of the sleeve 31 is adjusted, and the direction of the opening 32 of the sleeve 31 is adjusted to the side away from the power distribution drawer 2, so that the shaft 1 36 can go out from the opening 32 again, and the fixed state between the shaft 1 36 and the sleeve 31 is released. At this time, the power distribution drawer 2 is adjusted to the closed side, and the power distribution drawer 2 can be rotated with the shaft 1 36 at the closed side as the origin, so that the power distribution drawer 2 is opened to one side, and the angle adjustment is completed;

[0050] The angle of each power distribution drawer 2 can be adjusted according to the use requirements, so that two adjacent power distribution drawers 2 can be used at the same time;

[0051] If the power distribution drawer 2 needs to be disassembled, the rotating shaft 36 on both sides is separated from the shaft sleeve 31, and the power distribution drawer 2 can be disassembled;

[0052] In the process of pulling out the distribution drawer 2, the support rod 41 will also move synchronously, so as to achieve the purpose of supporting the distribution drawer 2 from the bottom, thereby achieving the protective effect of preventing the distribution drawer 2 from falling and reducing the wear of parts caused by tilting; when the distribution drawer 2 is adjusted in angle, the bolts located on the open side of the distribution drawer 2 are removed to release the fixation between this end of the support rod 41 and the cross bar 42, and then when the distribution drawer 2 is adjusted in angle, the support rod 41 is synchronously adjusted in angle through the rotating shaft 44, thereby driving the cross bar 42 to move together, so that it always maintains the purpose of supporting the distribution drawer 2.

[0053] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
