[0001] The utility model relates to the technical field of distribution cabinets, in particular to a distribution cabinet convenient for assembly. Background Art

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final equipment of the power distribution system.

[0003] When assembling existing distribution cabinets, components are generally fixed to the inner wall of the cabinet through bolts. However, since the components are directly fixed inside the cabinet by bolts and the internal space of the cabinet is small, the inner wall of the cabinet will interfere with the assembly of the staff, making the assembly troublesome. And existing distribution cabinets generally dissipate heat through heat dissipation slots, resulting in the heat generated by the components during operation not being able to dissipate quickly, and the use effect is poor. For this reason, we propose a distribution cabinet convenient for assembly. Content of the Utility Model

DETAILED DESCRIPTION

[0025] 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.

[0026] Reference Figures 1-4 A power distribution cabinet that is easy to assemble includes a shell 8, a leg 1 is installed at the bottom of the shell 8, a fixing plate 16 is provided inside the shell 8, both sides of the fixing plate 16 are fixed to the inner wall of the shell 8, and the sides of the fixing plate 16 are symmetrically installed with strip fixing seats 13, and the sides of the two strip fixing seats 13 are correspondingly provided with a plurality of accommodating grooves 11, and a plurality of strip mounting plates 10 are provided between the two strip fixing seats 13, and a plurality of components are installed on the sides of the strip mounting plates 10, and both ends of the strip mounting plates 10 extend into the corresponding accommodating grooves 11. In actual use, the staff can fix the components on the strip mounting plates 10, and then move the two ends of the strip mounting plates 10 into the accommodating grooves 11, which is convenient for assembly.

[0027] like Figure 1 and Figure 3 As shown, each strip fixing seat 13 is provided with a slide groove 23 at the upper end of the accommodating groove 11, and the interior of each slide groove 23 is slidably connected with a limit plate 22, and both ends of each strip mounting plate 10 are provided with a limit groove 21, and the bottom of each limit plate 22 extends into the limit groove 21. In actual use, when the two ends of the strip mounting plate 10 are moved into the accommodating groove 11, the staff moves the limit plate 22 downward so that the bottom end of the limit plate 22 extends out of the slide groove 23, and the bottom end of the limit plate 22 moves into the limit groove 21, so that the strip mounting plate 10 can be fixed and the fixation is convenient.

[0028] It should be noted that, as Figure 3 shown, a magnetic attraction block 24 is installed at the top of each sliding groove 23. When the limiting plate 22 moves to the topmost position, the magnetic attraction block 24 is adsorbed and fixed to the top of the limiting plate 22. During actual use, the staff moves the limiting plate 22 to the uppermost end of the sliding groove 23. At this time, the top of the limiting plate 22 is adsorbed and fixed on the magnetic attraction block 24, and the bottom of the limiting plate 22 moves into the sliding groove 23, which will not interfere with the installation of the strip-shaped mounting plate 10.

[0029] As Figure 2 shown, a plurality of mounting grooves 19 are equidistantly formed on the side of the outer shell 8 away from the opening. A refrigerating sheet 18 is installed inside each mounting groove 19. The cold end of the refrigerating sheet 18 extends into the outer shell 8 and has a spacing from the fixing plate 16. The hot end of the refrigerating sheet 18 is located outside the outer shell 8. During actual use, the cold end of the refrigerating sheet 18 can cool the inside of the outer shell 8, so that the components can be cooled by heat dissipation, and the components can work within a preset temperature range.

[0030] It should be noted that a plurality of heat dissipation fins 17 are installed at the hot end of each refrigerating sheet 18. Through the heat dissipation fins 17, the contact area between the hot end of the refrigerating sheet 18 and the air can be increased, and the heat dissipation speed can be accelerated.

[0031] It should be noted that, as Figure 1 and Figure 2 shown, a heat dissipation cover 5 is provided on one side of the outer shell 8. The heat dissipation cover 5 covers one side of the outer shell 8, and a surrounding edge 7 is installed on the edge of one side of the heat dissipation cover 5 and the edge of the outer shell 8. The two surrounding edges 7 are fixed to each other. The refrigerating sheet 18 can be blocked by the heat dissipation cover 5 to prevent the refrigerating sheet 18 from being damaged by rain.

[0032] As Figure 1 and Figure 4 shown, at least one first mounting hole 4 is formed at the bottom of the heat dissipation cover 5. A heat dissipation fan 3 is installed inside the first mounting hole 4. A plurality of exhaust grooves 6 are formed at the top of both sides of the heat dissipation cover 5. The external air can be blown into the heat dissipation cover 5 by the heat dissipation fan 3 to dissipate heat from the hot end of the refrigerating sheet 18, so that the refrigerating sheet 18 can work normally, and the high-temperature air after heat dissipation is discharged from the heat dissipation cover 5 through the exhaust grooves 6.

[0033] As Figure 1 and Figure 4As shown, L-shaped connecting plates 14 are installed at both the upper and lower ends of the fixing plate 16. The edges of the L-shaped connecting plates 14 are fixed to the inner wall of the outer shell 8. At least one second mounting hole 15 is provided at the top of the L-shaped connecting plate 14 located below. A circulation fan 20 is installed inside the second mounting hole 15. At least one ventilation hole 12 is provided at the bottom of the L-shaped connecting plate 14 located above. The circulation fan 20 can blow the low-temperature air cooled by the refrigeration sheet 18 towards the components to cool the components. Then the air returns to the cold end of the refrigeration sheet 18 through the ventilation hole 12 again for circulating cooling.

[0034] It should be noted that a snap-action temperature control switch 27 is installed on one side of one of the strip-shaped mounting plates 10. The snap-action temperature control switch 27 is respectively connected to the refrigeration sheet 18, the circulation fan 20 and the cooling fan 3 through wires. During actual use, the snap-action temperature control switch 27 can check the heat generated by the components during operation. When the temperature is higher than the preset value, the snap-action temperature control switch 27 closes, and the refrigeration sheet 18, the circulation fan 20 and the cooling fan 3 work to cool the components.

[0035] It should be noted that as Figure 1 shown, a cabinet door 9 is connected to the side of the outer shell 8 near the opening through a hinge. The cabinet door 9 is in sealed cooperation with the opening of the outer shell 8, and the other end of the cabinet door 9 is fixed to the other side of the outer shell 8 through a lock. Under the action of the cabinet door 9, the opening of the outer shell 8 can be blocked and sealed. In this way, while preventing the air cooled by the refrigeration sheet 18 from leaking from the gap between the cabinet door 9 and the outer shell 8, it can also block the external rainwater to prevent the rainwater from seeping into the outer shell 8 and damaging the components.

[0036] Specifically, during the assembly of the present utility model, the staff installs the components on the strip-shaped mounting plate 10, and then moves the two ends of the strip-shaped mounting plate 10 into the corresponding receiving grooves 11. Then the staff pushes the limiting plate 22 downward. The top end of the limiting plate 22 disengages from the magnetic attraction block 24, and the bottom end of the limiting plate 22 moves out of the sliding groove 23 and into the limiting groove 21 opened on the strip-shaped mounting plate 10, and the strip-shaped mounting plate 10 can be fixed. Then, it is only necessary to connect the components through wires to complete the assembly. During use, the refrigeration sheet 18 works to cool and lower the temperature inside the outer shell 8 at the cold end. At the same time, the circulation fan 20 works to blow the air cooled by the refrigeration sheet 18 towards the surface of the components to cool and dissipate the heat of the components. Then the air will return to the cold end of the refrigeration sheet 18 through the ventilation hole 12 for circulating cooling. At the same time, the cooling fan 3 works, and the cooling fan 3 blows the external air towards the hot end of the refrigeration sheet 18 to cool the hot end of the refrigeration sheet 18, so that the refrigeration sheet 18 can maintain normal operation. In this way, the heat dissipation speed of the components will be accelerated, and the working temperature of the components will be maintained within the preset temperature range.

[0037] Furthermore, as Figure 3 shown, a plurality of through grooves 25 are formed in the side surface of each strip fixing base 13, each through groove 25 communicates with the corresponding sliding groove 23, and a dial 26 is installed on one side of each limiting plate 22. One end of the dial 26 extends outside the through groove 25. By means of the dial 26, the difficulty of adjusting the limiting plate 22 can be reduced, and it is convenient to move the limiting plate 22.

[0038] Furthermore, as Figure 1 shown, the exhaust groove 6 is inclined downward, so that when it rains, rainwater will not flow into the heat dissipation cover 5 from the exhaust groove 6, improving the waterproof effect.

[0039] Furthermore, as Figure 1 and Figure 2 shown, a rain shield 2 with openings at both ends is installed at the bottom of the heat dissipation cover 5. The rain shield 2 covers the bottom of the first mounting hole 4. Under the action of the rain shield 2, the bottom of the heat dissipation fan 3 can be blocked. When it rains, rainwater will flow along the rain shield 2 to the ground instead of flowing to the heat dissipation fan 3 to damage the heat dissipation fan 3.

[0040] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
