Description

Technical Field

[0001] This invention relates to the field of distribution box technology, and more particularly to a distribution box installation device. Background Technology

[0002] As a very important electrical device, the distribution box plays a role in the power supply line to rationally distribute electrical energy to various electrical facilities. Whether it is for long-term electricity use in daily life or temporary electricity use on construction sites, the distribution box is indispensable. Therefore, the distribution box needs to be installed firmly and reliably to ensure safe and stable power use.

[0003] Currently, the commonly used methods are to install a support frame on the wall and fix the distribution box to the support frame, or to use an embedded installation method by reserving installation space during the wall pouring. However, these methods limit the number and fixed position of the distribution boxes, and it is inconvenient to add new distribution boxes or change the installation position of existing distribution boxes when electricity demand changes. Chinese Patent Publication No. CN216598707U, published on May 24, 2022, entitled "An Installation Device for a Distribution Box", discloses a distribution box installation device, including connectors, snap-fit ​​pieces, and clamps, which can fix the distribution box on a circular upright. However, this installation device relies on the upright for fixation, making it inconvenient to disassemble and move. When multiple distribution boxes need to be centrally installed, each distribution box needs to be installed separately, which is inconvenient for expanding the installation device and for managing and maintaining the wiring of the distribution boxes. Summary of the Invention

[0004] This invention overcomes the problems of existing distribution box installation devices, such as difficulty in disassembly and relocation, inability to expand installation space, and inconvenience in line management of multiple distribution boxes. It provides a distribution box installation device with a detachable installation structure, which can be easily and quickly disassembled and assembled. By setting up a rectangular mounting frame with multiple installation spaces and multiple layers that can be stacked, it is convenient to centrally set up and expand the number of multiple distribution boxes. It adopts a unified distribution wiring method, which makes the line layout reasonable and easy to manage.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0007] Corner posts are set at the four corners of a rectangular mounting frame, and corner post lugs are connected to both ends of the corner posts;

[0008] Side posts are set on the four sides of the rectangular mounting frame. Side post ear plates are connected to both ends of the side posts. Adjacent side post ear plates and corner post ear plates are detachably connected and fixed by connecting plates.

[0009] The hollow cross-shaped column has four pairs of detachable partition plates on its sides, which are fixed to different side columns respectively. Each pair of partition plates is arranged in parallel at intervals and has a partition plate wiring hole. The cross-shaped column has a column wiring hole between each pair of partition plates.

[0010] The rectangular mounting frame has at least one layer. The lower end of the upper side column and the upper end of the lower side column are detachably fixed through side column ear plates. The lower end of the upper corner column and the upper end of the lower corner column are detachably fixed through corner column ear plates. The partition plate divides the interior of each rectangular mounting frame into four rectangular spaces for placing distribution boxes. The corner columns, side columns, and cross-shaped columns are all equipped with support members for supporting the bottom corners of the distribution box. The distribution box is installed on the support members with the box door facing outward. The inlet and outlet holes on the side of the distribution box are connected in sequence to the wiring holes of the partition plate and the wiring holes of the column.

[0011] Preferably, a pad is installed on the support member, and the distribution box is installed on the pad.

[0012] Preferably, a top baffle for dust and water protection is installed above the uppermost rectangular mounting bracket.

[0013] Preferably, the cross-shaped column is provided with a wiring divider, which divides the space inside the cross-shaped column into four parts that are connected to the wiring holes of different columns.

[0014] Preferably, the cable routing hole of the column is a long strip extending in the vertical direction.

[0015] Preferably, the base is composed of a rectangular mounting frame with all partitions removed, and the base is fixed to the ground or a trolley with casters by corner post lugs and side post lugs.

[0016] Preferably, a lateral limiting rod for confining the distribution box within the rectangular mounting frame is also connected between the corner post and the side post.

[0017] This application also provides a method for installing a distribution box, using a distribution box installation device as described in any of the above solutions. The installation method includes the following steps:

[0018] S1: Set up the base and fix the corner posts and side posts of the first layer of rectangular mounting bracket to the base, and connect and fix the corner posts and side posts with connecting plates;

[0019] S2: Install the first layer of cross-shaped columns and fix them to the side columns with partition plates;

[0020] S3: Install the distribution box on the support of the corner column, side column and cross-shaped column with the box door facing outwards, and move the distribution box so that the inlet and outlet holes on its side are connected to the wiring holes of the partition plate and the wiring holes of the column in sequence.

[0021] S4: Insert the wire from below the cross-shaped column and pass it through the wire routing holes of the column, the wire routing holes of the partition plate, and the inlet and outlet holes on the side of the distribution box in sequence. Then fix the wire in the distribution box to complete the wiring.

[0022] S5: The rectangular mounting brackets of the second layer and above are stacked and installed upwards in the same way as the first layer. Adjacent rectangular mounting brackets are connected and fixed by corner post lugs and side post lugs.

[0023] The present invention has at least the following beneficial effects: (1) It adopts a detachable structure, which facilitates the storage, transportation and reuse of the device; (2) The device has strong scalability, and can quickly provide installation space when adding new distribution boxes; (3) It adopts a central wiring method, and the wiring of each distribution box is centrally set up while being relatively independent, with a reasonable layout, which facilitates wiring and maintenance; (4) The device is movable as a whole, does not depend on the wall, and is convenient to adjust the installation position; (5) The spacing between each distribution box is relatively wide, and the wiring holes of the partition plate can take into account both wiring and heat sink installation, which can provide a good heat dissipation effect for the distribution box.

[0032] like Figure 1-4 As shown, the distribution box mounting device provided by the present invention includes a base and a rectangular mounting frame fixed thereon. The rectangular mounting frame includes:

[0033] Angle post 1 is set at the four corners of the rectangular mounting frame. Angle post 1 is connected to corner post ear plate 2 at both ends. Angle post 1 has an L-shaped cross section. As a convenient material selection option, the material of angle post 1 can be a thicker angle steel. Angle post ear plate 2 is also L-shaped and is set horizontally on the outside of angle post 1. Screw holes are opened on the corner post ear plate 2.

[0034] Side posts 3 are set on the four sides of the rectangular mounting frame. Side post ear plates 4 are connected to both ends of side posts 3. Adjacent side post ear plates 4 and corner post ear plates 2 are detachably connected and fixed by connecting plates 5. The side posts 3 have a U-shaped cross section. As a material choice for convenience, the side posts 3 can be made of channel steel. The side post ear plates 4 are horizontally set on the outer side of the channel steel. The side post ear plates 4 have screw holes. The two ends of the connecting plates 5 are respectively bolted to the upper or lower sides of the corner post ear plates 2 and the side post ear plates 4. The connecting plate 5 located at the bottom is connected to the upper side of the corner post ear plates 2 and the side post ear plates 4 to facilitate the connection of the base or other devices below. The connecting plate 5 located at the top is connected to the lower side of the corner post ear plates 2 and the side post ear plates 4 to facilitate the installation of the top baffle 12 and other sealing devices above.

[0035] The hollow cross-shaped column 6 has four pairs of detachable partition plates 7 fixed to different side columns 3 on its sides. Each pair of partition plates 7 is arranged parallel at intervals and has partition plate wiring holes 8. The cross-shaped column 6 has column wiring holes 9 between each pair of partition plates 7. The cross-shaped column 6 includes protruding parts extending in four directions. Each protruding part has a pair of partition plates 7 clamped on both sides and fixed with bolts. The other end of the partition plate 7 is connected to the side column 3. If the side column 3 is a channel steel, the partition plates 7 are fixed in pairs to the legs of the channel steel. The position of the partition plate wiring holes 8 matches the position of the inlet and outlet holes of the actual distribution box. After the distribution box is installed, each distribution box has partition plate wiring holes 8 on two sides. One partition plate wiring hole 8 is used for wiring, and the other partition plate wiring hole 8 can be used to install external devices such as heat dissipation devices. Each column wiring hole 9 is between a pair of partition plates 7 and is connected to the partition plate wiring holes 8 on both sides for wiring.

[0036] The rectangular mounting frame has at least one layer. The lower end of the upper side post 3 and the upper end of the lower side post 3 are detachably fixed through the side post ear plate 4. The lower end of the upper corner post 1 and the upper end of the lower corner post 1 are detachably fixed through the corner post ear plate 2. The partition plate 7 divides the interior of each rectangular mounting frame into four rectangular spaces for placing the distribution box. The corner post 1, side post 3 and cross-shaped column 6 are all provided with support members 10 for supporting the bottom corner of the distribution box. The distribution box is installed on the support member 10 with the box door facing outward. The inlet and outlet holes on the side of the distribution box are connected in sequence to the partition plate wiring hole 8 and the column wiring hole 9. The side columns 3, corner columns 1, and cross-shaped columns 6 have the same height. The outline of each layer of rectangular mounting frame is a regular cuboid to facilitate installation layer by layer upwards. The bottom surface of the rectangular space divided by the partition plate 7 does not need to be designed as a square, but is adapted to the shape of the distribution box. The distribution box can be placed or removed without removing the frame structure such as the columns and side columns 3. The support member 10 is set at the lower end of the corner columns 1, side columns 3, and cross-shaped columns 6 and its height is the same as that of the corner column ear plate 2 and the side column ear plate 4. The size and strength of the support member 10 are based on being able to stably support the distribution box. The height of the rectangular space is higher than that of the distribution box to adjust the position of the distribution box and provide space for ventilation and heat dissipation.

[0037] When using this distribution box installation device, first install the base, then fix the corner post 1 and the side post 3 in a counterclockwise or clockwise direction on the top of the base, and use the connecting plate 5 to connect and fix the corner post 1 and the side post 3 to form the outer frame. Place the cross-shaped column 6 in the middle of the frame, and fix the cross-shaped column 6 and the side post 3 with the partition plate 7. In this way, the single-layer rectangular mounting frame is assembled. Place the distribution box on the support 10. The boxes on the same side should have the same door orientation and be unobstructed when open. The wiring work can be carried out after the distribution box position is fixed or before the distribution box is placed. Each distribution box should run its wiring through the nearest partition plate wiring hole 8 and column wiring hole 9, and the column wiring hole 9 that is not occupied by other distribution boxes should be selected first. When increasing the number of layers in the rectangular mounting frame, the positions of the side posts 3 and corner posts 1 of the upper and lower layers correspond and are connected and fixed by the side post lugs 4 and corner post lugs 2. The upper-layer cross-shaped uprights 6 are aligned and placed above the lower-layer cross-shaped uprights 6, and can be fixed with limiting components. The positioning of the cross-shaped uprights 6 is mainly achieved by the side posts 3 and the partition plates 7. After the device is installed, it can be moved as a whole. When it is necessary to reduce the number of layers, the components can be disassembled in the reverse order of installation and reassembled for the next use.

[0038] This distribution box installation device features a detachable structure, allowing for quick disassembly after use, facilitating storage, transportation, and reuse. It boasts a large capacity, providing installation space for four distribution boxes per floor, with additional floors available to meet further needs, offering strong scalability and rapid provision of installation space for new distribution boxes. A centralized wiring system is employed, with wiring from all distribution boxes converging in the cross-shaped columns 6, while the wiring exiting from the wiring holes 9 on different columns remains relatively independent, resulting in a rational layout that facilitates wiring organization and maintenance. The entire device is movable and does not require wall mounting, allowing it to be installed anywhere with available mounting surface.

[0039] In another technical solution, such as Figure 1 As shown, a pad 11 is installed on the support member 10, and the distribution box is installed on the pad 11. By setting the pad 11, the bottom of the distribution box can be subjected to more even force, and the installation position of the distribution box in the rectangular space is not limited by the position of the support member 10, and can be freely adjusted.

[0040] A top baffle 12 for dust and water protection is installed above the uppermost rectangular mounting bracket. The edge of the top baffle 12 extends beyond the rectangular mounting bracket. The top baffle 12 is directly bolted to the uppermost side post lug 4 and corner post lug 2. The top baffle 12 allows the device to better withstand weather conditions and is suitable for outdoor installation.

[0041] In another technical solution, such as Figure 4As shown, a wiring divider 13 is installed inside the cross-shaped column 6. The wiring divider 13 divides the space inside the cross-shaped column 6 into four parts, each connected to a wiring hole 9 on a different column. The four column spaces divided by the wiring divider 13 are used for wiring of different distribution boxes on a single-layer rectangular mounting rack, allowing for more independent and organized wiring of the distribution boxes. Distribution boxes on different layers in the same location share the wiring space, and can be distinguished by simply binding and marking the wires of different distribution boxes.

[0042] The cable routing hole 9 on the column is a long, vertically extending strip. This elongated shape allows for better observation of the internal cable routing and facilitates maintenance operations.

[0043] In another technical solution, such as Figure 2 and Figure 3 As shown, the base consists of a rectangular mounting frame with all partition plates 7 removed. The base is fixed to the ground or a trolley with casters via corner brackets 2 and side brackets 4. By using the rectangular mounting frame, the base does not require separate design, and the corner brackets 2 and side brackets 4 can be bolted to the ground or a trolley for easy relocation. After removing the partition plates 7, the wires can be more easily threaded through the wire routing holes 9 on the cross-shaped uprights 6 of the base.

[0044] A lateral limiting rod is also connected between corner post 1 and side post 3 to confine the distribution box within the rectangular mounting frame. Since the rectangular space within the mounting frame is larger than the distribution box, a lateral limiting rod is installed between corner post 1 and side post 3 to further improve the stability and safety of the distribution box installation. One end of the lateral limiting rod is rotatably connected to the corner post or side post, and the other end is detachably connected to the side post or corner post using a snap-fit ​​or other detachable structure. The lateral limiting component not only confines the distribution box but also provides ample adjustment space, making it convenient to open the box door when needed.

[0045] This application also provides a method for installing a distribution box, using a distribution box installation device as described in any of the above solutions. The installation method includes the following steps:

[0046] S1: Set up the base and fix the corner posts 1 and side posts 3 of the first layer rectangular mounting bracket to the base, and connect and fix the corner posts 1 and side posts 3 with the connecting plate 5;

[0047] S2: Set up the first layer of cross-shaped columns 6 and fix them to the side columns 3 with partition plates 7;

[0048] S3: Install the distribution box on the support 10 of the corner post 1, side post 3 and cross-shaped post 6 with the box door facing outwards, and move the distribution box so that the inlet and outlet holes on its side are connected to the wiring hole 8 of the partition plate and the wiring hole 9 of the post in sequence.

[0049] S4: Insert the wire from below the cross-shaped column 6 and pass it through the column wiring hole 9, the partition plate wiring hole 8 and the inlet and outlet holes on the side of the distribution box in sequence. Then fix the wire in the distribution box to complete the wiring.

[0050] S5: The rectangular mounting brackets of the second layer and the upper layer are stacked and installed upwards in the same way as the first layer. The two adjacent rectangular mounting brackets are connected and fixed by the corner post ear plate 2 and the side post ear plate 4.

[0051] This method allows for the rapid assembly and fixing of the distribution box installation device. The installation location is not dependent on the wall, allowing for more flexible installation of the distribution box in locations with concentrated power demand. The installation space can be adjusted according to the actual number of distribution boxes required. When adding a new distribution box, it can be directly installed in the remaining installation space of the rectangular mounting frame, or more installation positions can be provided by increasing the number of layers of the rectangular mounting frame. The wiring of the distribution box adopts a centralized wiring method, with the wiring of each distribution box converging in the cross-shaped column 6, avoiding the problems of messy wiring that is difficult to manage and affects maintenance.

[0052] The number of devices and processing scale described herein are for the purpose of simplifying the description of the invention. Applications, modifications, and variations of the invention will be readily apparent to those skilled in the art.

[0053] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made.
