Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinets, and more particularly to a distribution cabinet facilitating the installation of electrical components. Background Art

[0002] In modern power systems, as the core equipment for power distribution and control, distribution cabinets usually have mounting plates or mounting racks inside to fix electrical components such as circuit breakers, contactors, and relays. The installation process of traditional distribution cabinets is as follows: operators pre-install the components at the designated positions, complete mechanical fixation through bolt fasteners, and then connect each component one by one through wires, and finally connect to the main circuit to achieve the functions of power distribution and control. However, limited by the enclosed structure and space design of the distribution cabinet, the following significant defects exist in the prior art in practical applications:

[0003] The internal space of the distribution cabinet is usually relatively compact. When the depth of the cabinet body is large, it is difficult for operators to accurately position and fasten the components in the limited space. For example, when installing components near the rear wall of the cabinet body, due to the limited movement range of tools (such as screwdrivers and wrenches), it is easy to cause the bolts to be not fastened in place or the connectors to shift, affecting the installation quality and equipment stability. The lighting conditions inside the cabinet body are poor, and the deep cavity structure is prone to form shadow areas. In an environment with insufficient light, it is difficult for operators to clearly observe the installation positions of components, the markings of wiring terminals, or the wire routing directions, resulting in an increased risk of misoperation (such as stripped screws and incorrect wire connections), and at the same time significantly reducing the installation efficiency. In addition, due to the narrow space for components near the side wall or corner of the cabinet body, the operating angle of tools is limited, and it is necessary to repeatedly adjust the posture or use special tools (such as elbow screwdrivers), further increasing the installation complexity. Therefore, it is necessary to provide a distribution cabinet facilitating the installation of electrical components to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a distribution cabinet facilitating the installation of electrical components, aiming to solve the problems mentioned in the background art.

[0005] To achieve the above object, the present invention provides the following technical solution. A power distribution cabinet facilitating the installation of electrical components includes a power distribution cabinet body and a cabinet door. The cabinet door can be opened to 180 degrees, making the installation vision more open and improving the installation efficiency. An installation plate is vertically arranged in the power distribution cabinet body. The installation plate is used for installing electrical components. A plurality of guide frames are fixedly connected to the side of the installation plate. A plurality of guide plates are fixedly connected to the inner side wall of the power distribution cabinet body. The guide frames are slidably connected with the guide plates in a one-to-one correspondence. A limiting component is arranged at the inner end of the power distribution cabinet body, and a supporting component is arranged at the outer end of the power distribution cabinet body. The installation plate can move between the inner end and the outer end of the power distribution cabinet body. When the installation plate is located at the inner end, the installation plate is limited and fixed by the limiting component. When the installation plate is located at the outer end, the back of the installation plate is supported by the supporting component.

[0006] As a further solution of the present invention, the supporting component includes a plurality of supporting baffles. A plurality of through grooves are arranged at the outer edge of the side wall of the power distribution cabinet body. The supporting baffles pass through the through grooves, and the supporting baffles and the through grooves are in a one-to-one correspondence. A side plate is connected to the outer end of the supporting baffle. The side plate is fixedly connected to the side wall of the power distribution cabinet body by bolts.

[0007] As a further solution of the present invention, the limiting component includes a limiting block. The limiting block is close to the inner end of the power distribution cabinet body. A groove is arranged on the inner side surface of the guide plate. The side surface of the limiting block is slidably connected with the inner wall of the groove. The limiting block and the inner end surface of the groove are connected by a return spring. The surface of the limiting block facing the outer end of the power distribution cabinet body is an inclined surface. When the return spring is not affected by external force, most of the limiting block will extend out of the groove.

[0008] As a further solution of the present invention, an upper through groove and a lower through groove are respectively arranged on the upper half and the lower half of the installation plate. An upper movable plate is arranged at the top end of the upper through groove. The upper movable plate can move vertically along the upper through groove. A lower movable plate is arranged at the bottom end of the lower through groove. The lower movable plate can move vertically along the lower through groove.

[0009] As a further solution of the present invention, a plurality of guide posts are fixedly installed on the back of the installation plate. The plurality of guide posts are all vertically arranged. Guide sleeves are fixedly connected to the backs of the upper movable plate and the lower movable plate. The guide posts are slidably connected with the inner side surfaces of the guide sleeves. The upper movable plate and the lower movable plate are detachably connected to the guide posts by screws.

[0010] As a further solution of the present invention, several mounting brackets are provided in the lower half of the upper through groove, and several mounting brackets are also provided in the upper half of the lower through groove. The mounting brackets are detachably connected to the guiding columns by screws; the height value of the upper through groove is greater than or equal to twice the height value of the upper movable plate, and the height value of the lower through groove is greater than or equal to twice the height value of the lower movable plate.

[0011] As a further solution of the present invention, several rollers are installed at the bottom end of the mounting plate. The rollers roll along the bottom surface of the power distribution cabinet body, and several heat dissipation grooves are provided on the side surface of the power distribution cabinet body.

[0012] In summary, the beneficial effects of the present invention are as follows:

[0013] Through the arrangement of the guiding plate and the guiding frame, the mounting plate can move between the inner end and the outer end of the power distribution cabinet body. During formal installation, the mounting plate is pulled to the outer end of the power distribution cabinet body. In this way, the lighting conditions are better, the installation operation range is not limited, the installation of electrical components will be more convenient and rapid, and the wiring terminal markings and wire routing on the electrical components can be seen more clearly, and the guiding connection efficiency will also be greatly improved. Through the arrangement of the limiting component, the movement and shaking of the mounting plate are avoided; through the arrangement of the supporting component, the back surface of the mounting plate is supported to facilitate the installation work of electrical components.

The guide frames 5 and the guide plates 4 are in one-to-one correspondence. Through the arrangement of a plurality of guide plates 4 and guide frames 5, the installation plate 3 can move between the inner end and the outer end of the distribution cabinet body 1. When installing, the installation plate 3 is pulled to the outer end of the distribution cabinet body 1. In this way, without the obstruction of the cabinet body itself, the lighting condition is better, the installation operation range is not limited, the installation of electrical components will be more convenient and rapid, and the wiring terminal markings and wire routing on the electrical components can be seen more clearly, and the guiding connection efficiency will also be greatly improved; after the electrical components are installed and the guiding connection is completed, the installation plate 3 is pushed to the inner end of the distribution cabinet body 1.

[0027] In an embodiment of the present invention, a limiting component is provided at the inner side end of the distribution cabinet body 1, and a supporting component is provided at the outer side end of the distribution cabinet body 1. When the mounting plate 3 is located at the inner side end, the mounting plate 3 is limited and fixed by the limiting component to prevent the mounting plate 3 from moving and shaking; when the mounting plate 3 is located at the outer side end, the back surface of the mounting plate 3 is supported by the supporting component. After the mounting plate 3 is supported, the mounting plate 3 will not move backward, facilitating the installation work of electrical components.

[0028] Please refer to Figures 1 to 5 , in an embodiment of the present invention, the supporting component includes a plurality of supporting baffles 7. A plurality of through grooves 10 are provided at the outer edge of the side wall of the distribution cabinet body 1. The supporting baffles 7 pass through the through grooves 10, and the supporting baffles 7 correspond to the through grooves 10 one by one. The side surface of the supporting baffle 7 is slidably connected to the inner wall of the through groove 10. The outer side end of the supporting baffle 7 is connected with a side plate 11, and the side plate 11 is fixedly connected to the side wall of the distribution cabinet body 1 through a bolt 12, and the bolt 12 can be disassembled. When it is necessary to pull the mounting plate 3 to the outer side end of the distribution cabinet body 1, first remove the bolt 12 to make the supporting baffle 7 move outward to avoid interfering with the movement of the mounting plate 3. After the mounting plate 3 is pulled to the outer side end of the distribution cabinet body 1, make the supporting baffle 7 move inward. At this time, the supporting baffle 7 will support the back surface of the mounting plate 3.
