Description

Technical Field

[0001] This utility model relates to the field of power supply box technology, and in particular to a power supply box with adjustable internal space. Background Technology

[0002] In fields such as industrial control, communication base stations, and laboratory equipment, power supply chassis, as key devices that house core components such as power modules, filtering elements, and terminal blocks, must adapt to diverse equipment installation requirements in different scenarios. With the rapid development of power electronics technology, the specifications, power ratings, and layout forms of power supply components are becoming increasingly diverse.

[0003] In the existing technology, the internal compartment structure of a certain power supply chassis is rigid during use, making it difficult to flexibly match the installation size and space requirements of different models of components. This results in low equipment integration efficiency, insufficient space utilization, and frequent replacement of the chassis during later maintenance or component upgrades, which increases application costs. It has significant limitations and poor practicality. Utility Model Content

[0004] This utility model mainly provides a power supply chassis with adjustable internal space that can be adjusted at will according to actual needs, and the adjustment is very convenient.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a power supply chassis with adjustable internal space, comprising a power supply chassis body, partition grooves, mounting plates, mounting holes, connecting blocks, insert blocks, a drive structure, heat dissipation grooves, a housing, and a dustproof plate. Multiple partition grooves are provided, and these grooves are located at both ends of the inner wall of the power supply chassis body. A mounting plate is inserted into every two opposing partition grooves. The connecting block is fixed to one end of the mounting plate. The insert blocks are located on both sides of the connecting block, with the opposite ends of the two insert blocks inserted into the power supply chassis body. The connecting block contains a drive structure for driving the two insert blocks to move towards or away from each other. Heat dissipation grooves are provided at both ends of the power supply chassis body between every two partition grooves. The housing is fixed to both ends of the power supply chassis body. The dustproof plate is installed inside the housing. Multiple mounting holes are provided, and these holes are located inside the mounting plates.

[0006] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0007] In this invention, multiple partition slots are provided inside the power supply box body, and mounting plates are placed in these slots. This allows users to insert mounting plates into different slots according to their actual needs, thus dividing the space inside the power supply box body into multiple sections. The height of each section can be adjusted according to the position of the mounting plate, enhancing practicality. When installing the mounting plate, simply insert the mounting plate into the partition slot, rotate the rotating plate to drive the connecting column to rotate, which in turn drives the first bevel gear and its meshing second bevel gear to rotate, thereby driving the bidirectional screw to rotate. This causes the two moving plates to move towards or away from each other under the limitation of the limiting cavity, which in turn drives the two insert blocks to move towards or away from each other. When the two insert blocks move towards each other, they will be inserted into the power supply box body, thus limiting the position of the connecting block and achieving the effect of quick installation of the mounting plate. When the two insert blocks move towards each other, they will detach from the power supply box body and retract into the connecting block. At this time, the position of the connecting block is no longer limited, and the connecting block and mounting plate can be directly slid out, achieving the effect of quick disassembly.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Please see Figures 1-5 This utility model provides a technical solution: a power supply chassis with adjustable internal space, including a power supply chassis body 1, partition grooves 5, mounting plates 6, mounting holes 7, connecting blocks 8, inserts 9, a drive structure 10, heat dissipation grooves 17, a housing 18, and a dustproof plate 19. Multiple partition grooves 5 are used, and the partition grooves 5 are opened at both ends of the inner wall of the power supply chassis body 1. A mounting plate 6 is inserted into every two opposing partition grooves 5. A connecting block 8 is fixed to one end of the mounting plate 6. Inserts 9 are located on both sides of the connecting block 8, with the opposite ends of the two inserts 9 inserted into the power supply chassis body 1. A drive structure 10 is provided in the connecting block 8 for driving the two inserts 9 to move towards or away from each other. Heat dissipation grooves 17 are opened at both ends of the power supply chassis body 1 between every two partition grooves 5. The housing 18 is fixed to both ends of the power supply chassis body 1. The dustproof plate 19 is installed inside the housing 18. Multiple mounting holes 7 are used. Furthermore, the mounting hole 7 is located inside the mounting plate 6. By providing multiple partition slots 5 inside the power supply box body 1, and placing the mounting plate 6 in each partition slot 5, users can insert the mounting plate 6 into different partition slots 5 according to their actual needs. This divides the space inside the power supply box body 1 into multiple compartments, and the height of each compartment can be adjusted according to the position of the mounting plate 6, making it more practical. Through the operation of the drive structure 10, the two plug blocks 9 can be driven to move towards or away from each other. When the two plug blocks 9 move towards each other, they will be inserted into the power supply box body 1, thereby limiting the position of the connecting block 8 and achieving the effect of quickly installing the mounting plate 6. When the two plug blocks 9 move towards each other, they will detach from the power supply box body 1 and retract into the connecting block 8. At this time, the position of the connecting block 8 is no longer limited, and the connecting block 8 and the mounting plate 6 can be directly slid out, achieving the effect of quick disassembly.

[0016] like Figure 1-5 As shown, the drive structure 10 includes a bidirectional screw 1001 installed in the connecting block 8. Both ends of the outer wall of the bidirectional screw 1001 are threaded with movable plates 1002. The opposite ends of the two inserts 9 pass through one side of the connecting block 8 and are fixed to the two movable plates 1002 respectively. The connecting block 8 has a limiting cavity 1003 that matches the movable plates 1002. By rotating the bidirectional screw 1001, the two movable plates 1002 move towards or away from each other under the limitation of the limiting cavity 1003, thereby driving the two inserts 9 to move towards or away from each other.

[0017] like Figure 1-5As shown, a first bevel gear 11 is installed on the outer wall of the bidirectional screw 1001. The first bevel gear 11 is meshed with a second bevel gear 12. A connecting post 13 is fixed to one end of the second bevel gear 12. The end of the connecting post 13 away from the second bevel gear 12 passes through the connecting block 8 and is fixed with a rotating plate 14. Both ends of the bidirectional screw 1001 are rotatably connected to the connecting block 8. By rotating the rotating plate 14, the user drives the connecting post 13 to rotate, which in turn drives the first bevel gear 11 and the meshing second bevel gear 12 to rotate, thereby driving the bidirectional screw 1001 to rotate.

[0018] like Figure 1-5 As shown, a friction-enhancing sleeve 16 is fixed on the outer wall of the rotating plate 14, and a damping ring 15 is installed inside the connecting block 8. The connecting column 13 is rotatably connected to the connecting block 8 through the damping ring 15. By setting the damping ring 15, the damping of the rotation of the connecting column 13 can be increased, and the phenomenon of accidental rotation can be avoided. By setting the friction-enhancing sleeve 16, the friction force of the user rotating the rotating plate 14 is increased, and the phenomenon of slippage can be avoided.

[0019] like Figure 1-5 As shown, a door panel 2 is connected to one end of the power supply box body 1 by a pin. The door panel 2 and the power supply box body 1 are both equipped with a latch 3. A first handle 4 is fixed on the outer wall of the door panel 2. The door panel 2 can be locked by the latch 3.

[0020] like Figure 1-5 As shown, a mounting block 20 is fixed to one end of the dust cover 19 outside the housing 18. The mounting block 20 is fixed to the housing 18 by bolts. A second handle 21 is fixed to the top of the mounting block 20. The second handle 21 makes it easy to pull the mounting block 20, thereby moving the dust cover 19 out for replacement.

[0021] The device's operation and working principle are as follows: When in use, rotating the rotating plate 14 drives the connecting column 13 to rotate, which in turn drives the first bevel gear 11 and its meshing second bevel gear 12 to rotate, thus rotating the bidirectional screw 1001. This causes the two moving plates 1002 to move towards or away from each other under the limitation of the limiting cavity 1003, thereby causing the two insert blocks 9 to move towards or away from each other. When the two insert blocks 9 move towards each other, they insert into the power supply box body 1, thus limiting the position of the connecting block 8 and achieving the effect of quickly installing the mounting plate 6. When the two insert blocks 9 move towards each other, they detach from the power supply box body 1 and retract into the connecting block 8, at which point they no longer... The position of the connecting block 8 is defined, allowing the connecting block 8 and the mounting plate 6 to be slidably removed for quick disassembly. This device has multiple partition slots 5 inside the power supply box body 1, and the mounting plate 6 is placed in each partition slot 5. This allows the user to insert the mounting plate 6 into different partition slots 5 according to actual needs, thereby dividing the space inside the power supply box body 1 into multiple spaces. The height of each space can be adjusted according to the position of the mounting plate 6. The mounting holes 7 are provided to allow for the installation of electronic components. On the other hand, the unused mounting holes 7 can connect the various spaces inside the power supply box body 1, allowing air circulation and better heat dissipation.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
