Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a distribution box base. Background Technology

[0002] As the core equipment of the power distribution system, the distribution box needs to be used temporarily outdoors in situations such as construction sites, concerts, and emergency rescue to achieve rapid deployment, flexible power supply, or short-term power guarantee. The installation stability of the distribution box is directly related to its normal use and power supply safety. Therefore, the distribution box is installed with a base. The base is set to keep the bottom of the distribution box away from the ground to achieve the effect of moisture and corrosion prevention.

[0003] The currently used base is a rectangular structure welded from a steel frame. The lower end of the distribution box is fixedly connected to the steel frame. This has the following problems: Problem 1: The base is welded on-site from a steel frame, which takes a long time; Problem 2: The base obtained by welding the steel frame is an integral structure. When the distribution box needs to be moved, the entire base needs to be moved together. It is heavy and inconvenient to move. When the distribution box is no longer needed, the base will be forcibly cut and scrapped. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a power distribution box base that is easy to disassemble and assemble, simple to operate, and saves time and effort.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

Each of the side frames and end frames has an extension frame at its opposite end. The extension frames of the side frames and end frames are connected by an end connection structure. The end connection structure includes an inner connector and an outer connector. The inner connector fits into the ends of the side frames and end frames, and both sides of the outer connector are connected to the extension frames of the side frames and end frames. The inner connector and the outer connector are fixedly connected.

[0007] In this way, a rectangular structure is formed by the side frames and end frames to support the distribution box. To improve overall integrity, adjacent side frames and end frames are fixedly connected by end connection structures. When the base is not needed, the end connection structures can be disassembled for easy transportation, storage, and reuse. When connecting the side frames and end frames, the inner connector fits against the ends of the side frames and end frames, and the outer connector connects to the extension frames of the side frames and end frames. After the inner connector and outer connector are fixedly connected, a stable connection is formed, fixing the end frames and side frames to obtain a stable rectangular support structure. The distribution box is then placed on the rectangular support structure and fixedly connected to it.

[0008] Preferably, the extension frame is L-shaped and a card plate is fixedly installed at the outer end of the extension frame. The card plate has several card slots. The external connector is L-shaped and has protruding card blocks on both sides that engage with the card slots.

[0009] Preferably, the inner connector includes a base plate, a top plate, and a U-shaped frame for connecting the base plate and the top plate. Several sets of plug-in seats are fixed inside the U-shaped frame. Each plug-in seat includes two insert plates fixedly installed inside the U-shaped frame, forming a slot between the two insert plates. The outer connector has plug blocks fixedly installed in the same number as the plug-in seats. These plug blocks can be inserted into the slots. Through holes are provided directly opposite each other on the insert plates and plug blocks. A locking nut is fixedly installed on the lower surface of the lowest plug plate. The locking nut is coaxial with the through hole. A locking bolt passes through the through holes on the insert plates and plug blocks and is threadedly connected to the locking nut.

[0010] Preferably, two support members are also fixedly installed between the top plate and the top plate, and the extension frame is in contact with the surface of the support members.

[0011] Preferably, a reinforcing member is also fixedly installed between the top plate and the bottom plate, the reinforcing member being L-shaped and located between the two supporting members.

[0012] Preferably, side guards are provided on the outer sides of both side frames, and elongated holes are provided on the side guards.

[0013] Preferably, both the side frame and the end frame are made of rectangular steel tubing.

[0014] In summary, this distribution box base has the advantages of easy disassembly and assembly, simple operation, and saving time and effort. Attached Figure Description

[0022] like Figure 1-6 As shown, a distribution box base includes two side frames and two end frames 2 arranged opposite each other, forming a rectangular structure. Extension frames 3 are provided at the opposite ends of each side frame and end frame. The extension frames of the side frames and end frames are connected by an end connection structure 4. The end connection structure includes an inner connector 5 and an outer connector 6. The inner connector fits into the ends of the side frames and end frames, and the two sides of the outer connector are connected to the extension frames of the side frames and end frames. The inner connector and the outer connector are fixedly connected.

[0023] In this way, a rectangular structure is formed by the side frames and end frames to support the distribution box. To improve overall integrity, adjacent side frames and end frames are fixedly connected by end connection structures. When the base is not needed, the end connection structures can be disassembled for easy transportation, storage, and reuse. When connecting the side frames and end frames, the inner connector fits against the ends of the side frames and end frames, and the outer connector connects to the extension frames of the side frames and end frames. After the inner connector and outer connector are fixedly connected, a stable connection is formed, fixing the end frames and side frames to obtain a stable rectangular support structure. The distribution box is then placed on the rectangular support structure and fixedly connected to it.

[0024] In implementation, the extension frame is L-shaped and a retaining plate 7 is fixedly installed at its outer end. The retaining plate has several retaining slots 8. The outer connector is L-shaped, and retaining blocks 9 protrude from both sides of the outer connector to engage with the retaining slots. The extension frame and the outer connector are connected through the retaining slots and retaining blocks.

[0025] In implementation, the inner connector includes a base plate 10, a top plate 11, and a U-shaped frame 12 for connecting the base plate and the top plate. Several sets of plug-in seats are fixed inside the U-shaped frame. Each plug-in seat includes two plug plates 13 fixedly installed inside the U-shaped frame, forming a slot between the two plug plates. The outer connector has plug blocks 14 fixedly installed on it, the same number as the plug-in seats. These plug blocks can be inserted into the slots. Through holes 15 are provided directly opposite the plug plates and plug blocks. A locking nut is fixedly installed on the lower surface of the lowest plug plate. The locking nut is coaxial with the through hole. A locking bolt 16 passes through the through holes in the plug plates and plug blocks and is threadedly connected to the locking nut. When connecting the outer connector to the inner connector, the outer connector is brought close to the inner connector, and the plug blocks are inserted into the slots. The locking bolt passes through the through holes in the plug plates and plug blocks and is threadedly connected to the locking nut, thus achieving fixation.

[0026] In practice, two support members 17 are fixedly installed between the top plate and the top plate, and the extension frame is in contact with the surface of the support members. This creates a connection between the extension frame and the support members, improving connection stability.

[0027] During implementation, a reinforcing member 18 is fixedly installed between the top plate and the bottom plate. The reinforcing member is L-shaped and located between the two supporting members. The strength of the internal connecting member is improved by the addition of the reinforcing member.

[0028] In implementation, side blocks 19 are provided on the outer sides of both side frames, and elongated holes 20 are provided on the side blocks. Side screws pass through the elongated holes and connect to the distribution box, which can avoid drilling holes at the bottom of the distribution box and also make the connection between the distribution box and the base more stable.

[0029] In practice, both the side frames and end frames are made of rectangular steel tubing, which facilitates manufacturing.

[0030] When connecting the side frame and the end frame in the end connection structure, the following steps are performed:

[0031] 1. The inner connector is placed inside the side frame and end frame, and the extension frame fits against the support frame on the inner connector;

[0032] 2. When the outer connector is close to the inner connector, the insert block is inserted into the slot and the locking block is engaged in the slot. The outer connector is used to limit the extension frame and set the extension frame between the inner connector and the outer connector.

[0033] 3. The locking bolt passes through the holes on the insert plate and the insert block and is connected to the locking nut by thread, fixing the inner connector to the outer connector; after the connection is completed, the base is obtained;

[0034] 4. Place the distribution box on the base, and use the side screws to pass through the elongated holes and drive into the side wall of the distribution box to fix the distribution box on the base.

[0035] When the base is not needed, the end frame and side frame can be separated by removing the side screws and locking bolts.

[0036] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
