Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical cabinet technology, and in particular to an electrical cabinet with a protective structure. Background Technology
[0002] Electrical cabinets are made of steel and are used to protect components and ensure their proper functioning. They are generally made of either hot-rolled or cold-rolled steel. Cold-rolled steel is softer than hot-rolled steel and is more suitable for electrical cabinet manufacturing. Electrical cabinets have a wide range of applications, primarily in the chemical, environmental protection, power, metallurgical, industrial, nuclear power, fire safety monitoring, and transportation sectors.
[0003] Traditional electrical cabinets, lacking protective structures, are easily affected by external environmental factors such as dust and moisture, which can enter the cabinet and damage electrical components, reducing their lifespan. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of lacking a protective structure when electrical cabinets are used in the external environment. Therefore, we propose an electrical cabinet with a protective structure.
[0005] To achieve the above objectives, this application adopts the following technical solution: an electrical cabinet with a protective structure, including a base plate, support plates fixed on both sides of the top of the base plate, mounting plates slidably installed on the opposite surfaces of the support plates, a cabinet body installed on the top of the mounting plates, a protective plate provided on the top of the cabinet body, a groove opened on the surface of the support plates, connecting plates fixed at both ends of the mounting plates, the connecting plates slidably installed inside the grooves, a housing fixed at both ends on one side of the connecting plates, a knob threadedly connected to the side wall of the housing, a limit block fixed at one end of the knob located inside the housing, a horizontal plate slidably connected inside the housing, an insert plate fixed on one side of the horizontal plate, and multiple slots arranged longitudinally on one side of the support plate.
[0006] Preferably, springs are fixed at both ends of the inner wall of the housing, and the other end of the springs is fixed to the cross plate.
[0007] Preferably, limit rods are fixed on both sides inside the housing, and grooves that cooperate with the limit rods are provided at both ends of the cross plate.
[0008] Preferably, the limiting block is elliptical in shape.
[0009] Preferably, two sliders are fixed at both ends of the mounting plate, and the opposite surface of the support plate is provided with a groove for cooperating with the sliders.
[0010] Preferably, both ends of the top of the mounting plate are provided with drainage grooves, and both ends of the top of the base plate are provided with guide grooves, with the guide grooves located below the drainage grooves.
[0011] Preferably, both sides of the cabinet are provided with heat dissipation vents, and the interior of the heat dissipation vents is provided with filter plates.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] In this invention, by turning the knob, the limiting block fixed to it is rotated and moved away from the horizontal plate. At this time, the horizontal plate is no longer squeezed by the limiting block and is pushed by the spring's rebound force, causing the insert plate to disengage from the slot. This releases the fixation between the connecting plate and the support plate. Subsequently, the user can adjust the height of the cabinet to create a larger space between the bottom of the cabinet and the ground, preventing rainwater from flowing and seeping in along the bottom plate surface and protecting electrical equipment from water damage.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0021] Reference Figures 1-5As shown, this utility model provides a technical solution: an electrical cabinet with a protective structure, including a base plate 1, support plates 2 fixed on both sides of the top of the base plate 1, mounting plates 3 slidably installed on the opposite surfaces of the support plates 2, a cabinet body 4 installed on the top of the mounting plates 3, a protective plate 5 provided on the top of the cabinet body 4, a groove 6 opened on the surface of the support plates 2, connecting plates 7 fixed at both ends of the mounting plates 3, the connecting plates 7 slidably installed inside the groove 6, a housing 8 fixed at both ends of one side of the connecting plates 7, a knob 9 threadedly connected to the side wall of the housing 8, a limit block 10 fixed at one end of the knob 9 located inside the housing 8, a horizontal plate 11 slidably connected inside the housing 8, and an insert plate 12 fixed on one side of the horizontal plate 11. The support plate 2 has multiple slots 13 on one side that cooperate with the insert plate 12. The slots 13 are arranged longitudinally. Springs 14 are fixed at both ends of the inner wall of the housing 8. The other end of the springs 14 is fixed to the horizontal plate 11. By turning the knob 9, the limiting block 10 fixed to it is rotated and moved away from the horizontal plate 11. At this time, the horizontal plate 11 is no longer squeezed by the limiting block 10 and is pushed by the rebound force of the spring 14, which drives the insert plate 12 to disengage from the inside of the slot 13. This releases the fixation between the connecting plate 7 and the support plate 2. Then the user can adjust the height of the cabinet 4 to create a larger space between the bottom of the cabinet 4 and the ground, preventing rainwater from flowing and seeping in along the surface of the bottom plate 1 and protecting the electrical equipment from water damage.
[0022] Reference Figure 4 As shown in this embodiment: both sides of the housing 8 are fixed with limit rods 15, and both ends of the horizontal plate 11 are provided with grooves 16 that cooperate with the limit rods 15. Through the structure of the limit rods 15 and the grooves 16, the movement trajectory of the horizontal plate 11 can be restricted to prevent it from deviating and improve stability.
[0023] Reference Figure 4 As shown in this embodiment, the limiting block 10 is elliptical in shape. The elliptical design of the limiting block 10 reduces the contact area between the limiting block 10 and the horizontal plate 11, thereby making the movement between the limiting block 10 and the horizontal plate 11 smoother and less strenuous.
[0024] Reference Figure 2 As shown in this embodiment: two sliders 17 are fixed at both ends of the mounting plate 3, and the opposite side of the support plate 2 is provided with a groove 18 that works with the sliders 17. Through the structure of the sliders 17 and the groove 18, the vertical movement direction of the mounting plate 3 can be restricted, preventing the mounting plate 3 from tilting and improving the stability when adjusting the cabinet 4.
[0025] Reference Figure 2As shown in this embodiment: both ends of the top of the mounting plate 3 are provided with drainage grooves 19, and both ends of the top of the base plate 1 are provided with guide grooves 20. The guide grooves 20 are located below the drainage grooves 19. Through the structure of the drainage grooves 19 and the guide grooves 20, rainwater on the mounting plate 3 can fall onto the base plate 1 through the drainage grooves 19 and be discharged through the guide grooves 20, thus preventing rainwater from accumulating on the top of the base plate 1 and causing dampness.
[0026] Reference Figure 5 As shown in this embodiment: heat dissipation vents 21 are provided on both sides of the cabinet 4. A filter plate 22 is installed inside the heat dissipation vent 21. Through the structure of the heat dissipation vent 21 and the filter plate 22, the heat dissipation performance of the base plate 1 can be improved, preventing electrical equipment from being damaged due to overheating. At the same time, the filter plate 22 can filter the air entering the base plate 1, preventing dust and other impurities from entering the base plate 1, and ensuring a clean operating environment for the electrical equipment.
[0027] Working principle: By turning knob 9, the user rotates the fixed limiting block 10 away from the horizontal plate 11. At this point, the horizontal plate 11, no longer compressed by the limiting block 10, is pushed by the rebound force of spring 14, causing the insert plate 12 to disengage from the slot 13. This releases the connection between the connecting plate 7 and the support plate 2. The user can then adjust the height of the cabinet 4 to create a larger space between the bottom of the cabinet 4 and the ground, preventing rainwater from flowing down the surface of the bottom plate 1 and protecting electrical equipment from water damage. The structure of the limiting rod 15 and the groove 16 restricts the movement trajectory of the horizontal plate 11, preventing it from shifting and improving stability. The elliptical design of the limiting block 10 reduces the contact area between the limiting block 10 and the horizontal plate 11, thus... The structure of the limit block 10 and the horizontal plate 11 makes the movement between them smoother and less strenuous. The structure of the slider 17 and the slide groove 18 can limit the vertical movement of the mounting plate 3, prevent the mounting plate 3 from tilting, and improve the stability when adjusting the cabinet 4. The structure of the drain groove 19 and the guide groove 20 allows rainwater on the mounting plate 3 to fall onto the base plate 1 through the drain groove 19 and be discharged through the guide groove 20, preventing rainwater from accumulating on the top of the base plate 1 and causing dampness. The structure of the heat dissipation vent 21 and the filter plate 22 can improve the heat dissipation performance of the base plate 1 and prevent electrical equipment from being damaged by overheating. At the same time, the filter plate 22 can filter the air entering the base plate 1, preventing dust and other impurities from entering the base plate 1 and ensuring a clean operating environment for the electrical equipment.
