Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and more specifically to a low-voltage power distribution cabinet that is easy to install and its installation components. Background Technology

[0002] Low-voltage distribution cabinets are electrical devices used for multiple functions, including distributing electrical energy, controlling and protecting circuits, and metering electrical equipment. They are mainly used in low-voltage power supply systems and can rationally distribute electrical energy from power sources such as transformers to different power branches or terminal equipment, playing a key role as an energy transfer station. Wall-mounted low-voltage distribution cabinets are a special type of low-voltage distribution cabinet installation. Unlike floor-standing distribution cabinets, they are installed by fixing the distribution cabinet to the wall surface using specialized installation structures such as brackets and supports. This installation method can make full use of wall space and reduce the floor area occupied by the distribution cabinet, making it particularly suitable for places with relatively limited indoor space and high requirements for floor space utilization.

[0003] When installing a traditional wall-mounted distribution cabinet, the cabinet is usually lifted first to ensure that the mounting holes on the cabinet are accurately aligned with the expansion bolts already fixed to the wall. Then, the cabinet is slowly hung on the bolts so that it can rest stably against the wall. During this process, operators can use some simple tools to assist in the process, such as a small pry bar, to make fine adjustments to the position of the cabinet, thereby achieving the purpose of convenient and accurate mounting. Therefore, the installation process requires the cooperation of multiple people and is time-consuming and labor-intensive. However, if the distribution cabinet is heavy, it is often difficult to ensure the safety and smooth progress of the entire process by relying solely on manpower to lift and hang it on the wall. In view of this situation, it becomes necessary to use lifting equipment to assist in the installation. Small cranes and electric hoists are common lifting equipment. However, using these lifting equipment to assist in the installation also has certain drawbacks. Not only does it make the entire installation process more time-consuming and labor-intensive, but it also increases the installation cost. Utility Model Content

[0026] In this embodiment, by setting up the adjustment device 2, the height of the main body 1 of the power distribution cabinet can be quickly adjusted after the adjustment device 2 and the fixing device 3 are assembled.

[0027] A mounting component for a conveniently installed low-voltage distribution cabinet, the specific components of which are as follows:

[0028] The fixing device 3 includes a fixing ear 32 fixedly connected to the wall by expansion screws. A back plate 31 is fixedly connected to the side of the fixing ear 32. Limiting seats 33 are fixedly connected to both ends of the back plate 31 near the main body 1 of the distribution cabinet. Limiting rods 34 and toothed plates 35 are fixedly connected to the opposite surfaces of the two limiting seats 33. A sliding seat 36 is slidably connected to the outer surface of the limiting rods 34.

[0029] In this implementation scheme, by setting the adjustment device 2 and the fixing device 3, the back plate 31 is attached to the wall and fixed by the fixing ear 32. The main body of the distribution cabinet 1 is placed on the ground, and the fixing seat 21 and the sliding seat 36 are fixedly connected together. By rotating the rotating rod 24, the drive gear 210 can be driven to rotate. Through the meshing of the tooth plate 35, the fixing seat 21 and the main body of the distribution cabinet 1 are lifted upward as a whole. A single person can complete the installation of the main body of the distribution cabinet 1 more quickly without the aid of other lifting equipment, reducing the construction time of the entire project.

[0030] Specifically, the worm gear 29 and the drive gear 210 are both rotatably connected inside the fixed base 21. The surface of the drive gear 210 is meshed with the surface of the toothed plate 35. The surface of the sliding base 36 is provided with a sliding hole that matches the limit bar 34.

[0031] In this embodiment, by setting the meshing method of the worm 27 and the worm wheel 29 to drive the drive gear 210 to rotate, the drive gear 210 can be prevented from driving the worm 27 to rotate through the worm wheel 29, so that the main body of the distribution cabinet 1 can be positioned after being raised to a suitable position, thus enhancing stability.

[0037] In this embodiment, rotating the rotating rod 24 can drive the drive gear 210 to rotate.

[0038] The working principle and usage process of this utility model are as follows: During installation, first, reserve wall holes corresponding to the through holes on the fixing ears 32 at the specified positions on the wall. Then, place the back plate 31 in the specified positions and align it with the wall. Next, align the through holes on the fixing ears 32 with the wall holes and insert expansion bolts to secure them, thus fixing the fixing ears 32 to the wall. Then, place the main body 1 of the distribution cabinet 1 directly below the front surface of the fixing base 21 and slide the sliding base 36 so that the bolts inside the positioning holes 22 are inserted into the threaded holes on the surface of the sliding base 36 and tightened. After tightening, the surface of the drive gear 210 meshes with the surface of the toothed plate 35. Then, by rotating the rotating rod 24, the rotating rod 24 drives the worm gear 27 to rotate through the drive bevel gear 25 and the driven bevel gear 26. Through the meshing of the worm gear 27 and the worm wheel 29, the drive gear 210 is driven to rotate. Through the meshing of the toothed plate 35, the fixed base 21 and the main body of the distribution cabinet 1 are lifted upward as a whole. A single person can complete the installation of the main body of the distribution cabinet 1 more quickly without the aid of other lifting equipment, reducing the construction time of the entire project.
