Description

Technical Field

[0001] This utility model relates to the field of electrical equipment, specifically to a component mounting assembly for a distribution box. Background Technology

[0002] Distribution boxes are key devices in power systems used for centralized distribution, control, and protection of electrical energy. They typically consist of a metal or non-metal enclosure, internal electrical components (such as circuit breakers, contactors, fuses, and meters), and connecting wiring. Their core function is to receive electrical energy from the main power supply line and distribute it safely and efficiently to end-user equipment through branch circuits, while also providing overload and short-circuit protection. Distribution boxes are widely used in industrial, commercial, residential, and public facilities, and are a crucial link in the end-point management of power networks.

[0003] Inside the distribution box, various electrical components need to be fixed and arranged using mounting components. Currently used mounting components, such as the component mounting rack disclosed in patent CN209823199U, include two sets of telescopic square tubes and clamps. The telescopic square tubes consist of an inner tube and an outer tube. The clamps are divided into large clamps and small clamps. Each end of the large clamp has a first locking slot that engages with the outer tube. Both sides of the large clamp have first threaded holes through which a first bolt passes, making frictional contact with the outer wall of the outer tube. Each end of the small clamp has a second locking slot that engages with the inner tube. Both sides of the small clamp have second threaded holes through which a second bolt passes, making frictional contact with the outer wall of the inner tube. This is a fixed structure, and the spacing cannot be flexibly adjusted according to needs. With the diversification of various electrical components and their varying sizes, fixed mounting components cannot meet the requirements, leading to wasted installation space or a crowded layout that affects heat dissipation efficiency and subsequent maintenance. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a component mounting assembly for distribution boxes. This component mounting assembly allows for adjustable spacing according to actual needs, is simple to operate, and saves time and effort.

[0005] The objective of this utility model is achieved through the following solution:

[0006] A component mounting assembly for a distribution box includes two symmetrically arranged mounting frames and several placement frames for mounting components disposed between the two mounting frames.

When adjusting the position, the knob is pulled inward, the sliding rod moves along the sliding hole, and the bolt moves in the direction away from the mounting rack. After the placement rack is adjusted in place, the knob is pushed outward, the sliding rod moves outward, and the bolt is inserted into the jack, and the cooperation between the bolt and the jack is used to fix the position of the placement rack. The mounting rack is in a "U" shape, which increases the support strength for the placement rack.

[0011] Preferably, a compression spring is sleeved on the outer side of the sliding rod, and the compression spring is located between the slider and the intermediate plate.

[0012] Preferably, an outer plate is vertically and fixedly installed on the outer side of the intermediate plate. A sliding frame is fixedly installed on the outer plate. A sliding groove for slidingly fitting with the sliding frame is provided through the support bracket.

[0018] Figure 3 is Figure 2 the enlarged structural schematic diagram at position A in

[0019] Figure 4 the structural schematic diagram of the mounting bracket

[0020] Figure 5 the schematic diagram of the connection structure Specific implementation manner

[0021] As Figure 1-5 shown, a component mounting assembly for a distribution box includes two symmetrically arranged mounting brackets and a plurality of placement brackets 1 for mounting components arranged between the two mounting brackets. A plurality of oblong holes 2 are formed in the placement brackets, and both ends of the placement brackets are respectively connected to the mounting brackets through connection structures;

[0022] The connection structure includes an intermediate plate 3. An inner plate 4 is vertically and fixedly installed on the inner side of the intermediate plate. The inner plate is fixedly connected to the placement bracket. A sleeve 5 is fixedly installed on the outer side of the intermediate plate. A sliding hole coaxially arranged with the sleeve is formed through the intermediate plate. A sliding rod 6 is slidably fitted in the sliding hole. A knob 7 is fixed to the inner end of the sliding rod. A slider 8 capable of slidably fitting with the sleeve is fixed to the outer end of the sliding rod. A bolt 9 is fixedly installed at the outer end of the slider;

[0023] The mounting bracket includes a support plate 10 and a support frame 11 fixedly connected to the support plate. The support frame is in a "C" shape and the opening faces the support plate. A plurality of jacks 12 capable of being inserted and fitted with the bolt are formed through the support frame.

[0024] In this way, the mounting bracket is fixedly installed in the distribution box and can be welded or bolt-fixed to the distribution box. According to the position where the components need to be installed, the position of the placement bracket is adjusted. The placement bracket is fixed to the mounting bracket through the connection structure. The components are installed on the placement bracket. The oblong holes are provided, which also facilitates the bolts to pass through and is convenient for the installation of the components.

[0025] A plurality of jacks are provided on the mounting bracket and can be fitted with the bolt to realize the position adjustment of the placement bracket. When adjusting the position, the knob is pulled inward, the sliding rod moves along the sliding hole, and the bolt moves in the direction away from the mounting bracket. After the placement bracket is adjusted in place, the knob is pushed outward, the sliding rod moves outward, and the bolt is inserted into the jack. The cooperation between the bolt and the jack is used to fix the position of the placement bracket. The mounting bracket is in a "C" shape, which increases the support strength for the placement bracket.

[0026] During implementation, a compression spring 13 is sleeved on the outer side of the sliding rod. The compression spring is located between the slider and the intermediate plate. Through the arrangement of the compression spring, the slider can be pushed to move outward, so that the slider has a tendency to push outward, which can better ensure the tight insertion and fitting between the bolt and the jack and prevent the bolt from falling out due to vibration or external force.

[0027] In implementation, an outer plate 14 is vertically fixedly installed on the outer side of the intermediate plate, and a slide 15 is fixedly installed on the outer plate. A sliding groove 16, which slides through the support frame, engages with the slide. The outer plate and slide frame create a sliding pair between the intermediate plate and the support frame of the mounting frame. When adjusting the height of the mounting frame, the slide moves linearly along the sliding groove, providing guidance and preventing tilting. Simultaneously, this increases the contact area between the slide frame and the support frame, improving the overall structural stability.

[0028] In practice, the intermediate plate, inner plate, and outer plate are formed by sheet metal stamping. This improves overall integrity and facilitates manufacturing.

[0029] In practice, the inner plate and the mounting bracket are provided with through holes facing each other, and bolts pass through the through holes and are connected with nuts. This facilitates individual replacement or maintenance and is convenient to use.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications made to the present utility model by those skilled in the art without departing from the spirit of the present utility model shall fall within the protection scope of the present utility model.
