Description

Technical Field

[0001] The utility model relates to the technical field of distribution cabinets, and particularly relates to an intelligent power transmission and distribution cabinet with a fixing structure. Background Technique

[0002] Power transmission and distribution includes three aspects, namely power transmission, power transformation, and power distribution. Among them, power transmission refers to the transmission of electric energy. Through power transmission, power plants and load centers that are far apart are connected, enabling the development and utilization of electric energy to transcend geographical limitations; power transformation refers to the process of using certain equipment to transform the voltage from a low level to a high level or from a high level to a low level, and power distribution is the means of distributing electric power to users within the area where electric energy is consumed, directly serving users. The power transmission and distribution cabinet is a general term for motor control centers.

[0003] When the power transmission and distribution cabinet is in use, a variety of electrical components need to be installed inside, such as circuit breakers, contactors, intermediate relays, and thermal relays. Currently, the installation of these electrical components is generally through a fixing frame composed of an adjusting rod and a support beam and installed inside the cabinet. For example, in an installation structure of electrical components for a power distribution cabinet with a patent application number of 202210482809.7, when installing electrical components, the support beam is installed on the adjusting rod and then the electrical components are installed. However, when some electrical components need to be installed at a higher position, it requires maintenance personnel to raise their hands to install at a high place, which causes inconvenience to the installation of electrical components. Content of the Utility Model

The front surface of the fixing frame is recessed inward to form a number of limiting blind holes, and the centers of the limiting blind holes are located on the central axis of the installation slot. Between the two fixing frames, a fixing plate for installing electrical components is installed. At the opposite ends of the fixing plate, telescopic fixing columns that cooperate with the installation slot are symmetrically and fixedly connected. The telescopic ends of the telescopic fixing columns pass through the installation slot and are threadedly connected with limiting caps, and the limiting caps are embedded in the limiting blind holes.

[0007] Furthermore, at the opposite ends of the fixing plate, relief grooves that are adapted to the thickness of the fixing frame are opened.

[0008] Furthermore, a pull ring is hingedly connected to an end of the limiting cap away from the telescopic fixing column.

[0009] Furthermore, the retractable fixing column comprises a first fixing column connected to the fixing plate, a second fixing column is slidably connected to the inner cavity of the free end of the first fixing column, and a spring is connected between the second fixing column and the first fixing column.

[0010] Furthermore, the fixing plate is provided with a plurality of first strip holes for installing electrical components.

[0011] Furthermore, the top and bottom of the fixed plate are symmetrically slidably connected with a sliding plate, and the sliding plate is penetrated by a second strip hole that cooperates with the first strip hole.

[0012] The beneficial effects of the utility model are:

[0013] In this solution, the electrical components can be installed and fixed by means of the fixing plate, and after the electrical components are installed, the limiting cap can be pulled out of the limiting blind hole, and then the fixing plate can be slid to adjust the installation height of the electrical components and the spacing between the upper and lower adjacent electrical components to adapt to different usage environments.

[0021] Please refer to Figures 1-4 , the technical solution adopted by the utility model is:

[0022] An intelligent power transmission and distribution cabinet with a fixed structure comprises a cabinet body, wherein fixing frames are symmetrically fixedly connected to opposite side walls of the inner cavity of the cabinet body, a mounting groove is provided through the front and back sides of the fixing frame, and the mounting groove is arranged along the height direction of the fixing frame, the front side of the fixing frame is recessed inward to form a plurality of limiting blind holes, and the center of the limiting blind holes is located on the central axis of the mounting groove, a fixing plate for installing electrical components is installed between the two fixing frames, and retractable fixing columns cooperating with the mounting groove are symmetrically fixedly connected to the opposite ends of the fixing plate, the retractable end of the retractable fixing column passes through the mounting groove and is threadedly connected to a limiting cap, and the limiting cap is embedded in the limiting blind hole.

[0023] From the above description, it can be seen that the beneficial effects of the utility model are:

[0024] In this solution, the electrical components can be installed and fixed by means of the fixing plate, and after the electrical components are installed, the limiting cap can be pulled out of the limiting blind hole, and then the fixing plate can be slid to adjust the installation height of the electrical components and the spacing between the upper and lower adjacent electrical components to adapt to different usage environments. After the adjustment is completed, it is only necessary to loosen the limiting cap and re-embed the limiting cap into the limiting blind hole to limit and fix the fixing plate. The entire adjustment process is simple and convenient, and can be achieved without removing the limiting cap back and forth.

[0025] Furthermore, two opposite ends of the fixing plate are provided with easing grooves which are adapted to the thickness of the fixing frame.

[0026] From the above description, it can be seen that the clearance groove is set so that when the fixing plate and the fixing frame are connected, the clearance groove can limit the fixing plate, so that the fixing plate and the fixing frame can be quickly connected and ensure that the surface of the fixing plate can be flush with the fixing frame.

[0027] Furthermore, a pull ring is hingedly connected to an end of the limiting cap away from the telescopic fixing column.

[0028] From the above description, it can be seen that by setting the pull ring, the limit cap can be rotated through the pull ring when it is locked and fixed to achieve locking. At the same time, the limit cap and the telescopic end of the telescopic fixing column can also be pulled out of the limit blind hole through the pull ring, which is convenient for operation.

[0029] Furthermore, the retractable fixing column comprises a first fixing column connected to the fixing plate, a second fixing column is slidably connected to the inner cavity of the free end of the first fixing column, and a spring is connected between the second fixing column and the first fixing column.

[0030] It can be seen from the above description that the second fixing column can slide along the first fixing column to achieve the extension and retraction of the retractable fixing column, and the spring can provide restoring force and resistance.

[0031] Furthermore, the fixing plate is provided with a plurality of first strip holes for installing electrical components.

[0032] It can be seen from the above description that the use of strip-shaped mounting holes enables the fixing plate to adapt to mounting holes at different positions of different electrical components, thereby improving the applicability of the fixing plate.

[0033] Furthermore, the top and bottom of the fixed plate are symmetrically slidably connected with a sliding plate, and the sliding plate is penetrated by a second strip hole that cooperates with the first strip hole.

[0034] It can be seen from the above description that by arranging slidable sliding plates on both sides of the fixing plate, the installation area of ​​the fixing plate can be increased, so that different electrical components can be installed on the fixing plate.
