Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, and more specifically, to a connectable power distribution cabinet frame. Background Art

[0002] The distribution cabinet is a general term for the motor control center, which refers to the power distribution cabinet, lighting distribution cabinet, metering cabinet and other final equipment of the distribution system. When processing and manufacturing the distribution cabinet, it is generally necessary to build the overall frame of the distribution cabinet first, and then assemble other components on the frame.

[0003] During use, distribution cabinets need to be expanded to accommodate fixed or expanded installation requirements. Chinese patent application number 202223122901.7 discloses a connector for a distribution cabinet frame, which primarily uses bolts to secure the various connecting frames. This structure is complex and the steps involved are cumbersome. Utility Model Content

[0004] The utility model overcomes the shortcomings of the prior art and provides a connectable distribution cabinet frame, so as to solve the problem of the relatively complex distribution cabinet frame structure in the prior art.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A connectable distribution cabinet frame, comprising a main installation frame and an expansion installation frame;

[0007] The main installation frame is in a cubic shape, and one side of the main installation frame is provided with mutually parallel plug-in slots, and the plug-in slots are provided with fixing devices;

[0008] The expansion installation frame is in a cubic shape, and a plug-in plate matching the position and shape of the plug-in slot is provided on the interface between the expansion installation frame and the main installation frame;

[0009] The plug-in board is installed in the plug-in slot of the main installation frame and is fixed by the fixing device.

[0010] During installation, insert the plug-in board on the interface between the expansion installation frame and the main installation frame into the plug-in slot provided on the main installation frame to complete the installation of the expansion installation frame. After the installation is completed, the expansion installation frame is fixed to the main installation frame using the fixing device.

[0011] A further technical solution is that the fixing device is a card slot, and the card slot is arranged at the bottom of the plug-in slot;

[0012] An elastic hook-shaped card plate is provided at the bottom of the plug-in board of the expansion installation frame;

[0013] The elastic hook-shaped card plate pops out after reaching the card slot, fixing the plug plate in the plug slot.

[0014] By using an elastic hook-shaped card plate, the expansion mounting frame can be fixed very conveniently. Inserting the plug-in board into the plug-in slot will cause the elastic hook-shaped card plate to be squeezed and deformed, and finally it will rebound and reset to be stuck in the card slot, thereby facilitating the assembly of the connection frame and reducing the use of screws or other fixing devices.

[0015] A further technical solution is that the number of the expansion mounting frames is two, namely an upper mounting frame and a side mounting frame;

[0016] The upper mounting frame is mounted on the main mounting frame, and the main mounting frame is provided with two plug-in slots parallel to the long sides of the main mounting frame;

[0017] The side installation frame is installed on the side surface of the main installation frame. The side surface of the main installation frame is provided with two plug-in slots parallel to the high side of the main installation frame.

[0018] If the plug-in boards of the two expansion mounting frames are inserted on mutually parallel sides, interference will occur, so the plug-in slots of the upper mounting frame and the side mounting frame need to be set on mutually non-parallel sides.

[0019] A further technical solution is that the power distribution cabinet frame further includes a buffer plate;

[0020] There are two buffer plates, which are arranged on the inner side walls of the main installation frame and the extended installation frame.

[0021] The buffer plate is made of a material with greater friction, and the friction is increased by the contact between the buffer plate and the frame, which further makes the installation more stable and can also prevent the frame surface from being scratched and damaged.

[0022] A further technical solution is that a limit block is provided on the buffer plate;

[0023] Limiting grooves are provided on corresponding positions of the inner side walls of the main installation frame and the extended installation frame.

[0024] By providing the limiting blocks and the limiting grooves, the buffer plate can be prevented from moving forward and backward relative to the main installation frame and the extended installation frame.

[0025] A further technical solution is that the distribution cabinet frame further includes a guide rod, and the guide rod is arranged inside the main installation frame and the expansion installation frame;

[0026] The buffer plate and the guide rod are provided with guide holes at corresponding positions, and the guide rod passes through the guide holes of the buffer plate.

[0027] By providing the guide holes and the guide rods, the buffer plate can be prevented from tilting and moving relative to the main installation frame and the extended installation frame.

[0028] A further technical solution is that the distribution cabinet frame further includes threaded rods;

[0029] The bottom of the main installation frame and the expansion installation frame are provided with a sliding groove for placing the threaded rod;

[0030] The buffer plate is provided with a sliding portion corresponding to the slide groove, and the sliding portion is placed in the slide groove;

[0031] The sliding part is provided with a threaded hole corresponding to the thread of the threaded rod, and the thread directions of the sliding parts of different buffer plates arranged in the same main installation frame and the same extended installation frame are opposite;

[0032] The threaded rod passes through the threaded hole, and when the threaded rod rotates, the two buffer plates move in opposite directions.

[0033] When the threaded rod rotates, the mounting frame and the buffer plate inside the expansion mounting frame move in the opposite direction. When moving outward, the buffer plate tightens and clamps the frame, so it can be applied to frames of different sizes, and only one screw is needed to complete the operation.

[0034] Compared to existing technologies, the present invention offers at least the following advantages: The present invention utilizes a plug-in plate and slots, allowing installation between the main and side mounting frames by simply inserting the plug-in plate into the slots. The elastic hook-shaped clips are squeezed and deformed, then spring back into place, eliminating the need for screws or other fixing devices. Furthermore, the addition of a buffer plate not only enhances installation stability but also prevents scratches and damage to the frame surface. BRIEF DESCRIPTION OF THE DRAWINGS
