[0002] Metal armored low-voltage distribution cabinet is a kind of distribution equipment with metal shell and electrical components such as circuit breakers, fuses, contactors, and mutual inductors installed inside. These components are connected together through busbars to form a complete power distribution and control system. The metal armored shell not only has good protection performance, which can effectively prevent electric shock and equipment damage, but also has a high anti-corrosion and protection level to ensure stable operation of the equipment in harsh environments.

[0003] The metal armored low-voltage distribution cabinets currently in use still mostly require manual assembly during the assembly of internal electrical components. Due to the fixed structure of the cabinet, workers need to reach into the cabinet for installation, which is very inconvenient. The small installation space makes it even more inconvenient for multiple people to assemble at the same time, thereby delaying the equipment assembly time. Therefore, a metal armored low-voltage distribution cabinet that is easy to assemble is proposed. Summary of the invention

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Example: Refer to Figure 1-3, A metal-armored low-voltage power distribution cabinet that is convenient to assemble, including a device cabinet 1. A base 8 is installed on the bottom end of the device cabinet 1. Support legs are provided on the bottom surface of the base 8. An upper cavity 15 and a lower cavity 16 are respectively opened in the device cabinet 1. A second moving frame 4 is movably connected in the upper cavity 15, and a first moving frame 3 is movably connected in the lower cavity 16. A connecting frame 13 is provided on one side of the first moving frame 3. A limiting block 10 is installed on the second moving frame 4. A synchronous frame plate 12 is movably connected to one side of the limiting block 10. A spring catch rod 11 is connected in the synchronous frame plate 12. A contact piece 18 is movably connected to one side of the synchronous frame plate 12. The device cabinet 1 is fixedly installed on the top surface of the base 8. Two electric cabinet doors 2 are rotatably connected to the device cabinet 1. The two electric cabinet doors 2 are respectively rotatably connected to one side of the upper cavity 15 and the lower cavity 16. A partition is provided between the two cavities to achieve a better protection effect.

[0026] Specifically, support bars 9 are symmetrically installed on the outer surfaces of both sides of the device cabinet 1 for placing the protection piece 5 after it descends. A limiting slide bar is vertically installed on the upper side of the support bar 9, and the limiting slide bar is also fixedly installed on the outer surface of the device cabinet 1. A "U"-shaped protection piece 5 is slidably connected to the outside of the limiting slide bar. The protection piece 5 is movably connected to the outside of the electric cabinet door 2 to prevent the electric cabinet door 2 from being opened. A positioning rod 6 is threadedly connected to the top surface of the device cabinet 1 for positioning the protection piece 5 to avoid obstruction when opening the cabinet. The bottom end of the positioning rod 6 is threadedly connected to the protection piece 5.

[0027] Furthermore, both the first moving frame 3 and the second moving frame 4 are in an "L" shape. Arc-shaped bars are welded and installed on both sides of the bottom end of the first moving frame 3. An arc-shaped groove is opened between the inner walls of the base 8. The arc-shaped bars are slidably connected in the arc-shaped groove to limit the movement of the first moving frame 3 to avoid deviation. A plurality of rollers are also installed on the bottom surface of the first moving frame 3 to facilitate moving to the outside of the device cabinet 1 for assembly. Two connecting frames 13 are symmetrically installed. A hinge is connected between the two connecting frames 13 to prevent the movement range of the first moving frame 3 from being too large. One end of one of the connecting frames 13 is rotatably connected to the inner wall of the lower cavity 16, and the other end of the other connecting frame 13 is rotatably connected to the rear side surface of the first moving frame 3.

[0028] In this embodiment, a plurality of limit blocks 10 are installed on the upper and lower sides of the second mobile frame 4, and a plurality of slide bars 14 are symmetrically installed on the inner wall of the upper cavity 15. The limit blocks 10 are slidably connected to the outer surface of the slide bar 14 to support and stabilize the transportation of the second mobile frame 4. The ends of the limit blocks 10 on the lower side are provided with card slots for convenient connection with the synchronous frame plate 12. An extension plate is installed on the rear side surface of the top of the first mobile frame 3 to act in the same plane as the second mobile frame 4. Synchronous frame plates 12 are installed on the outer side of the extension plate. The synchronous frame plates 12 are movably connected between the inner walls of the device cabinet 1, and the spring clamping rods 11 are arranged on the synchronous frame plates 12. On the top, one end of the spring clamping rod 11 is connected in the clamping slot to achieve synchronous movement between the first movable frame 3 and the second movable frame 4. A fixed box 7 is also installed on the outer surface of the device cabinet 1 to adjust the connection between the first movable frame 3 and the second movable frame 4. An adjusting rod 17 is threadedly connected to the fixed box 7, and a contact piece 18 is connected to the inner end of the adjusting rod 17. The contact piece 18 is movably connected to the fixed box 7 to avoid self-rotation of the contact piece 18 during rotation. The other end of the spring clamping rod 11 is connected to the contact piece 18 to facilitate the adjustment of the pressure of the spring clamping rod 11. A rounded corner is provided on one side of the fixed box 7 to facilitate the connection of the spring clamping rod 11 to the device cabinet 1.

[0029] Working principle: When installing components, first rotate the adjustment rod 17, the contact piece 18 will gradually move inward until it is level with the device cabinet 1. At this time, the spring clamping rod 11 will be squeezed by the contact piece 18, and one end of the spring clamping rod 11 will be stuck in the card slot. When the electric cabinet door 2 is opened, the first movable frame 3 is pulled outward, and the spring clamping rod 11 will continue to contact the device cabinet 1 and will not loosen the connection with the limit block 10. At the same time, the second movable frame 4 will also move outward, achieving the effect of synchronous movement, which is convenient for simultaneous assembly of equipment;

[0030] When simultaneous movement is not required, the adjusting rod 17 should not be rotated before pulling. At this time, under the action of the spring, the other end of the spring clamping rod 11 is not connected to the limit block 10. When the first moving frame 3 is pulled, the second moving frame 4 will not be driven. When the spring clamping rod 11 moves to the rounded corner of the fixing box 7, the spring clamping rod 11 will reach a compressed state again to avoid jamming.

[0031] When the device cabinet 1 is in normal operation, the positioning rod 6 is rotated to lower the protective sheet 5 and place it on the support bar 9. The protective sheet 5 covers the outer side of the electric cabinet door 2 to prevent the electric cabinet door 2 from being opened during operation.
