Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, and in particular to an electrical cabinet with the function of fixing power components. Background Technology

[0002] An electrical cabinet is a device used to protect and control various electrical components and equipment in a power system. Inside the electrical cabinet, electrical components are usually supported by insulating brackets, and the various electrical components are connected by cables. Electrical components typically include circuit breakers, fuses, contactors, relays, switches, etc. These components can perform various electrical control operations.

[0003] In electrical cabinets, the stable installation of electrical components is one of the conditions for ensuring the normal operation of the circuit. A patent published in China (CN221688041U) entitled "An Outdoor Electrical Cabinet with Power Component Locking Function" discloses a method that utilizes a limiting groove, a lower pressure plate, a back plate, a lead screw, and an arc-shaped track. By flipping the back plate, the bottom of the back plate rotates around a rotating axis, allowing the limiting post to slide along the inside of the arc-shaped track. Flipping the back plate to a vertical position allows the connecting rod to align with the connecting sleeve at the top of the back plate. Rotating the lead screw allows the threaded sleeve to slide along the outside of the lead screw. During the downward movement of the back plate, the limiting groove locks the main body of the power component mounted on the mounting plate, making the adjustment of the power component installation more convenient. While this structure achieves the purpose of fixing electrical components, the arc-shaped track occupies a significant amount of space inside the electrical cabinet and restricts the internal layout of the cabinet during the rotation of the back plate structure, making operation cumbersome.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-9The electrical cabinet shown, which has the function of fixing electrical components, includes a cabinet body 1. The front surface of the cabinet body 1 is provided with a rotatable cabinet door 3, and the rear surface is provided with a removable back panel 11. The inner wall of the cabinet body 1 is symmetrically provided with guide rails 9. The top of the guide rails 9 is provided with a clamping device 10. The clamping device 10 includes a support rod 103. The front surface of the support rod 103 is provided with a clamping plate 105. The clamping plate 105 includes a clamping piece 1051. The rear surface of the clamping piece 1051 is provided with an insertion rod 1054. The side wall of the insertion rod 1054... A through hole 1053 is provided, and a mounting groove 106 is provided on the front surface of the support rod 103. The insertion rod 1054 can be inserted into the mounting groove 106 and slide horizontally. A threaded rod 101 is provided in the mounting groove 106. The extension end of the threaded rod 101 passes through the end of the support rod 103 and extends to the outside of the cabinet 1. A support block 102 is provided between two adjacent insertion rods 1054 in the mounting groove 106. A push plate 107 for pushing the insertion rod 1054 and the support block 102 is also provided on the outer wall of the support rod 103.

[0026] A pin 104 is provided on the rear surface of the support rod 103, and a socket adapted to the pin 104 is provided on the front surface of the back plate 11. In this embodiment, during the installation of electrical components, the electrical components are placed on the front surface of the support rod 103, and then two clamping plates 105 are symmetrically placed on the outer wall of the electrical components. Then, a support block 102 is placed from the rear surface of the support rod 103 into the mounting groove 106. The support block 102 is located between two adjacent clamping plates 105. Since the size of each electrical component is different, the distance between two adjacent clamping plates 105 is different. At this time, support blocks 102 of different lengths need to be selected. The support block 102 is made of plastic insulating material. The support rod 103 can be cut into a short support block 102 to meet the needs of use. Finally, the pins 104 at both ends of the support rod 103 are inserted into the holes of the back plate 11, and the back plate 11 is then connected to the cabinet 1 by bolts. At this time, the support rod 103 is located inside the cabinet 1, and the support rod 103 is more firmly placed under the action of the pins 104 and the back plate 11. Finally, the end of the threaded rod 101 is screwed into the mounting groove 106 of the support rod 103 from the outside of the cabinet 1 by thread engagement, and the push plate 107 presses the insert rod 1054 and the support block 102 together. The insert rod 1054 drives the clamping plate 1051 to clamp the electrical components.

[0027] like Figure 6As shown, the clamping plate 105 also includes a top plate 1055 fixed to the top of the clamping piece 1051. The top plate 1055 contacts the top of the support rod 103. A support bar 1052 is provided below the top plate 1055. The end of the support bar 1052 contacts the front surface of the support rod 103, making the clamping plate 105 more stable. A device body 8 is provided on one side of the front surface of the support rod 103. The clamping piece 1051 is attached to the outer wall of the device body 8. The clamping piece 1051 is made of aluminum and has an insulating coating on its surface. When the clamping piece 1051 contacts the device body 8, it can absorb the heat emitted by the device body 8.

[0028] like Figure 1 As shown, the bottom of the cabinet 1 is provided with heat dissipation holes 5, and the interior of the cabinet 1 is provided with heat dissipation mechanism 6. The heat dissipation mechanism 6 includes a support plate 63, the top of the support plate 63 is provided with a square hole, a perforated plate 64 is provided in the square hole, the top of the support plate 63 is also provided with an aluminum sheet 62, and the top of the aluminum sheet 62 is provided with a fan 61.

[0029] Specifically, when the heat dissipation mechanism 6 is in operation, the fan 61 blows the hot air inside the cabinet 1 downwards. The hot air passes through the aluminum sheet 62 and the perforated plate 64, then flows downwards through the heat dissipation holes 5, and is dissipated to the outside of the cabinet 1. It should be noted that the aluminum sheet 62 can absorb the heat inside the cabinet 1, which facilitates the concentration of heat, and then the fan 61 dissipates the heat.

[0030] like Figure 9 As shown, a threaded seat 12 is fixed to the side wall of the cabinet 1. A threaded hole is opened on the surface of the threaded seat 12. The extension end of the threaded rod 101 passes through the cabinet 1 and is connected to the threaded hole. An internal hexagonal nut is provided at the end of the threaded rod 101. The threaded rod 101 can be rotated by the cooperation of a hexagonal wrench and the internal hexagonal nut outside the cabinet 1. Under the guidance and support of the threaded seat 12, the threaded rod 101 is rotated counterclockwise. The end of the threaded rod 101 pushes the push plate 107 and presses the insertion rod 1054 and the support block 102 together. The threaded rod 101 is rotated clockwise. The threaded rod 101 drives the push plate 107 away from the insertion rod 1054, so that the insertion rod 1054 and the support block 102 are no longer in close contact, thus achieving the purpose of loosening.

[0031] like Figure 1 As shown, the top of the cabinet 1 is provided with a top cover 7, the bottom of the cabinet 1 is provided with a base plate 4, and the rear surface of the cabinet 1 is provided with a fixing plate 2. It should be noted that the cabinet 1 can be installed on the wall by attaching the fixing plate 2 to the wall and fixing it with bolts to meet the usage requirements. The base plate 4 can support the cabinet 1 to ensure that the bottom of the cabinet 1 does not directly contact the ground, so as to avoid liquids on the ground from contacting the cabinet 1 and causing short circuits or other dangers. The top cover 7 can withstand the impact of objects falling from above the cabinet 1 to properly protect the cabinet 1 and the circuit inside the cabinet 1.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
