Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to an outdoor power distribution cabinet that is easy to maintain. Background Technology

[0002] Distribution cabinets are a general term for motor control centers. They can be divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. Distribution cabinets are used in situations where the loads are relatively dispersed and there are fewer circuits, while motor control centers are used in situations where the loads are concentrated and there are more circuits. They can distribute the electrical energy of a certain circuit of the upper-level power distribution equipment to the nearest load, so as to provide protection, monitoring and control for the load.

[0003] However, when most existing distribution cabinets are damaged and require repair, the complex internal structure makes it difficult to access and repair certain corner components. Furthermore, the sides of most existing distribution cabinets are fixed, preventing access for inspection. This inconvenience hinders maintenance and repair. Therefore, it is necessary to propose a more easily maintainable outdoor distribution cabinet to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide an outdoor power distribution cabinet that is easy to maintain, in order to solve the problem mentioned in the background art that it is difficult to inspect and repair some corner parts inside the power distribution cabinet, and that most existing power distribution cabinets are fixed on both sides, making it impossible to open them for inspection and repair, which brings inconvenience to the inspection and maintenance of the power distribution cabinet.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an outdoor power distribution cabinet that is easy to maintain, including a mounting base, a fixing frame fixedly connected to the top of the mounting base, a fixing groove provided inside the fixing frame, a housing inserted into the fixing groove, and a mounting plate fixedly connected to the top of the mounting base;

[0006] The side of the fixed frame is provided with a disassembly mechanism, which includes a fixed block, a limiting rod, a movable plate, a pull rod, and a return spring. The side of the fixed block is fixedly connected to the side of the fixed frame, and the inside of the fixed block is slidably connected to the outside of the limiting rod. One end of the limiting rod is fixedly connected to the side of the movable plate, the side of the movable plate is fixedly connected to one end of the pull rod, and the side of the movable plate is fixedly connected to one end of the return spring.

[0007] Preferably, a limiting hole is provided on the outside of the box body, the limiting rod is inserted into the limiting hole, and the outside of the limiting rod is slidably connected to the inside of the fixed frame.

[0008] Preferably, one end of the return spring is fixedly connected to the inside of the fixed block, the outside of the pull rod is slidably connected to the inside of the fixed block, and the outside of the pull rod is slidably connected to the inside of the return spring. A slot is provided inside the pull rod.

[0009] Preferably, the mounting plate is located inside the housing, and electrical components are provided on the outside of the mounting plate;

[0010] The inside of the fixing groove is lined with a rubber sealing gasket.

[0011] Preferably, the exterior of the enclosure is hinged with an inspection door, and the top of the enclosure is fixedly connected with a rain cover.

[0012] Preferably, the side of the box is provided with heat dissipation holes, and a rainproof frame is fixedly connected to the side of the box. The side and bottom of the rainproof frame are provided with ventilation slots.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting up mounting bases, fixing frames, fixing slots, enclosures, mounting plates, disassembly mechanisms, limit holes, and inspection doors, when the distribution cabinet needs maintenance, simple routine maintenance of the electrical components inside the enclosure can be performed first using the inspection door. When the problem is more complex, the disassembly mechanism can be removed from limiting and fixing the enclosure. At this time, the enclosure can be pulled upwards to separate it from the fixing frame, avoiding the problem of the enclosure obstructing the maintenance process. This allows the electrical components installed on the outside of the mounting plate to be displayed without blind spots, making it easier to inspect some corner parts inside the distribution cabinet, thus bringing convenience to the maintenance of the distribution cabinet.

[0015] 2. By setting up a fixed frame, fixed groove, box body, fixed block, limit rod, movable plate, pull rod, return spring, limit hole, and slot, when it is necessary to disassemble the fixed frame from the box body, the pull rod can be pulled to the left. The return spring will be stressed and undergo elastic deformation. The pull rod will drive the limit rod to the left through the movable plate, causing the limit rod to separate from the limit hole on the outside of the box body. That is, the limit rod no longer limits and fixes the box body. When the slot inside the pull rod is pulled to the outside of the fixed block, the pin can be inserted into the slot to limit the movement of the box body. The limit rod is used to limit the position, preventing the return spring from causing the limit rod to reset. This facilitates quick disassembly of the fixing frame and the enclosure. When it is necessary to install the fixing frame and the enclosure, insert the enclosure into the fixing frame, remove the pin, and the compressed return spring will cause the limit rod to reset, allowing the limit rod to insert into the limiting hole and fix the enclosure. This process is simple and does not require any auxiliary tools to quickly install or remove the fixing frame and the enclosure, further facilitating the maintenance of the distribution cabinet.

[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 1-7 The outdoor power distribution cabinet shown includes a mounting base 1, a fixing frame 2 fixedly connected to the top of the mounting base 1, a fixing groove 3 opened inside the fixing frame 2, a box 4 inserted into the fixing groove 3, a mounting plate 11 fixedly connected to the top of the mounting base 1, the mounting plate 11 is located inside the box 4, and electrical components are arranged on the outside of the mounting plate 11. A rubber sealing gasket 12 is laid inside the fixing groove 3, which can improve the sealing between the fixing groove 3 and the box 4.

[0026] In addition, a disassembly mechanism is provided on the side of the fixed frame 2. The disassembly mechanism includes a fixed block 5, a limiting rod 6, a movable plate 7, a pull rod 8, and a return spring 9. The side of the fixed block 5 is fixedly connected to the side of the fixed frame 2, and the inside of the fixed block 5 is slidably connected to the outside of the limiting rod 6. One end of the limiting rod 6 is fixedly connected to the side of the movable plate 7. The side of the movable plate 7 is fixedly connected to one end of the pull rod 8, and the side of the movable plate 7 is fixedly connected to one end of the return spring 9. An inspection door 17 is hinged to the outside of the housing 4. When the distribution cabinet needs to be inspected, the electrical components inside the cabinet 4 can be inspected using the inspection door 17. When the problem is more complex, the disassembly mechanism can be removed from limiting and fixing the cabinet 4. At this time, the cabinet 4 can be pulled upward to separate it from the fixing frame 2. This avoids the problem of the cabinet 4 obstructing the inspection process, allowing the electrical components installed on the outside of the mounting plate 11 to be displayed without blind spots. This facilitates the inspection of some corner parts inside the distribution cabinet, thus bringing convenience to the maintenance of the distribution cabinet.

[0027] The enclosure 4 has a limiting hole 10 on its exterior. A limiting rod 6 is inserted into the limiting hole 10, and the exterior of the limiting rod 6 is slidably connected to the interior of the fixed frame 2. One end of the return spring 9 is fixedly connected to the interior of the fixed block 5. The exterior of the pull rod 8 is slidably connected to the interior of the fixed block 5, and the exterior of the pull rod 8 is slidably connected to the interior of the return spring 9. A slot 18 is provided inside the pull rod 8. When it is necessary to disassemble the fixed frame 2 from the enclosure 4, the pull rod 8 can be pulled to the left. The return spring 9 will undergo elastic deformation under force, and the pull rod 8 will move the limiting rod 6 to the left through the movable plate 7, causing the limiting rod 6 to separate from the limiting hole 10 on the exterior of the enclosure 4. That is, the limiting rod 6 no longer limits and fixes the enclosure 4. When the slot 18 inside the pull rod 8 is pulled to the exterior of the fixed block 5, a pin can be inserted into the slot 18 to limit the limiting rod 6, preventing the return spring 9 from driving the limiting rod. When the reset occurs, it facilitates the quick disassembly of the fixing frame 2 and the enclosure 4. When it is necessary to install the fixing frame 2 and the enclosure 4, insert the enclosure 4 into the interior of the fixing frame 2, remove the pin, and the compressed reset spring 9 will drive the limit rod 6 to reset, so that the limit rod 6 inserts into the limit hole 10 to limit and fix the enclosure 4. This process is simple to operate and does not require any auxiliary tools to quickly install or disassemble the fixing frame 2 and the enclosure 4, which further facilitates the maintenance of the distribution cabinet.

[0028] Finally, a rain cover 14 is fixedly connected to the top of the box 4, and ventilation holes 13 are provided on the side of the box 4. A rainproof frame 15 is also fixedly connected to the side of the box 4, and ventilation slots 16 are provided on the side and bottom of the rainproof frame 15. The rain cover 14 can be used to protect against rain, and the ventilation holes 13 can be used to dissipate heat from the inside of the box 4.

[0029] Working Principle: When maintenance of the distribution cabinet is required, simple routine maintenance of the electrical components inside the cabinet 4 can be performed first through the inspection door 17. When the problem is more complex, the disassembly mechanism can be removed from limiting and fixing the cabinet 4. At this time, the cabinet 4 can be pulled upwards to separate the cabinet 4 from the fixing frame 2, avoiding the problem of the cabinet 4 obstructing the maintenance process. This allows the electrical components installed on the outside of the mounting plate 11 to be displayed without blind spots, facilitating the maintenance of some corner parts inside the distribution cabinet, thus bringing convenience to the maintenance of the distribution cabinet. When it is necessary to disassemble the fixing frame 2 from the cabinet 4, the pull rod 8 can be pulled to the left. The return spring 9 will be subjected to force and undergo elastic deformation. The pull rod 8 will move the limit rod 6 to the left through the movable plate 7, so that the limit rod 6 and the cabinet are separated. The limiting hole 10 on the outside of the body 4 is separated, meaning that the limiting rod 6 no longer limits and fixes the body 4. When the slot 18 inside the pull rod 8 is pulled to the outside of the fixing block 5, the pin can be inserted into the slot 18 to limit the limiting rod 6, preventing the return spring 9 from driving the limiting rod 6 to reset. This facilitates the quick disassembly of the fixing frame 2 and the body 4. When it is necessary to install the fixing frame 2 and the body 4, the body 4 is inserted into the fixing frame 2, the pin is removed, and the compressed return spring 9 will drive the limiting rod 6 to reset, so that the limiting rod 6 is inserted into the limiting hole 10 to limit and fix the body 4. This process is simple to operate and does not require any auxiliary tools to quickly install or disassemble the fixing frame 2 and the body 4, further facilitating the maintenance of the distribution cabinet.
