Description

Technical Field

[0001] This utility model relates to the field of slide rail installation technology, specifically to a slide rail type electrical component installation structure for a distribution box. Background Technology

[0002] Electrical boxes are crucial electrical devices in power systems. They centrally house electrical components such as switches, circuit breakers, fuses, and relays, used for receiving, distributing, and controlling electrical energy. They also provide protection against short circuits, overloads, and leakage current, ensuring electrical safety. They are widely used in industrial, commercial, and civil buildings. Their structure generally consists of a box body, a door, and internal mounting beams or rails, offering various protection levels to adapt to different environments. Distribution box slide rails are standardized mounting rails installed inside the distribution box, typically made of metal with a special surface treatment to enhance conductivity and corrosion resistance. They provide convenient installation positions for electrical components such as circuit breakers and contactors. Components are directly snapped onto the slide rail using a snap-fit ​​structure, allowing for quick and flexible installation and disassembly, facilitating later maintenance and component replacement. The standardized specifications of the slide rails ensure compatibility with most brands and models of components, improving the versatility and flexibility of the internal layout of the distribution box, contributing to modular design, and enhancing assembly efficiency and ease of use.

[0003] A search revealed that CN204306406U discloses a portable slide rail for drawers, comprising a slide rail body with a first mounting hole and a second mounting hole. A first mounting bracket is fixedly connected to the first mounting hole by a first rivet, and a second mounting bracket is fixedly connected to the second mounting hole by a second rivet. The first mounting bracket has a rib plate forming a groove with the rib plate, and the second mounting bracket has a surrounding plate forming a locking pin with the surrounding plate. This utility model has a simple and reasonable structure. A mounting bracket is provided at each end of the slide rail, one of which has a groove that mates with a corresponding structure on the drawer. The rear end of the drawer is connected to the mating structure of the other bracket, thus completing the fixed connection between the drawer and the slide rail.

[0004] The problem with the aforementioned type of drawer slide for portable installation is that: 1. Reliance on external structure: Specific slots / pins need to be designed on the drawer, which cannot be directly adapted to the reserved slots of standardized distribution boxes, thus limiting its versatility.

[0005] 2. No fine-tuning after fixing: The rigid connection method using rivets and clips makes it difficult to adjust the position of the slide rail or disassemble it again after installation, resulting in insufficient maintenance flexibility. Utility Model Content

[0023] Please see Figures 1-4 This utility model provides a technical solution: a sliding rail type electrical component installation structure for a distribution box, including a distribution box body 1, with reserved slots 11 symmetrically opened on the inner wall of the distribution box body 1; Main component 2 is set in the reserved slot 11; The main component 2 includes a mounting base 21 and an inner groove 211 formed inside the mounting base 21; An internal screwing assembly 3 is installed inside the inner groove 211; The internal screwing assembly 3 includes an internal rotating rod 31 and a slide 32 that can rotate up and down with the internal rotating rod 31. Positioning components 4 are installed on the upper and lower outer sides of the mounting base 21, can follow the outer edge of the sliding column 42, and are fixed in the reserved slot 11; This design converts rotational mechanical energy into multi-point synchronous telescopic motion. By combining the threaded transmission internal screw assembly with the inclined thrust slope and rollers, it solves the problem that traditional slide rail installation relies on external structures and cannot be adjusted.

[0024] Please see Figure 2 Main component 2 also includes: The slide rail body 24 is fixedly connected to the outside of the mounting base 21; Please see Figure 3 The internal screw-in assembly 3 includes: Three sets of equally spaced threaded rings 312 are distributed on the outer surface of the inner rotating rod 31; Anti-slip sleeve 311 is fixedly connected to the end of the inner rotating rod 31; The protective sleeve 23 is mounted on the mounting base 21 and located on the anti-slip sleeve 311; The anti-slip sleeve 311 can increase the friction when the operator holds the inner rotating rod 31 and rotates it. Please see Figure 3 Main component 2 also includes: The partition plates 22 are fixedly connected to the inner side of the inner groove 211 at equal intervals; Each partition 22 is placed on both sides of each threaded ring 312; The partition 22 prevents the slide 32 from slipping off the threaded ring 312; Please see Figure 3 The internal screw-in assembly 3 also includes: Slopes 321 are formed on the upper and lower sides of the slide 32; Each slide block 32 is threaded to each threaded ring 312; This design allows the slide block 32 to slide horizontally as the anti-slip sleeve 311 rotates.

[0025] Please see Figure 4 and Figure 5 Positioning component 4 includes: The connecting plates 44 are fixedly connected at equal intervals to the upper and lower slots of the mounting base 21.

[0026] Positioning component 4 also includes: A limiting rod 43 is slidably connected to the inner side of the connecting plate 44; The sliding column 42 is fixedly connected to the outside of the limiting rod 43.

[0027] Positioning component 4 also includes: Rotate the roller 421 connected to the bottom of the slide column 42; Roller 421 corresponds to the position of slope 321; The contact between the roller 421 and the slope 321 makes the vertical movement of the sliding column 42 smoother; Positioning component 4 also includes: A spring ring 431 is fitted onto the outside of the limiting rod 43; The lower end of the spring coil 431 is fixedly connected to the sliding column 42; The upper end of the spring coil 431 is fixedly connected to the connecting plate 44.

The protective cover 23 can protect the inner rotating rod 31 and prevent accidental contact. Then, by turning the anti-slip sleeve 311, the inner rotating rod 31 rotates in the inner groove 211. At this time, the sliding block 32 connected to each threaded ring 312 can move horizontally synchronously and contact the roller 421 at the bottom of the sliding column 42. At this time, the sliding column 42 moves vertically under the influence of the slope 321 and pushes the top plate 41 outward of the reserved groove 11. The mounting base 21 cooperates with the upper and lower sets of top plates 41 to complete the positioning and tightening work in the reserved groove 11. With this design, the mounting base 21 and the slide rail body 24 can be quickly assembled in the distribution box 1 without the need for bolt drilling. Similarly, the anti-slip sleeve 311 can make the slide block 32 move and reset, and the top plate 41 will also be reset under the elastic action of the spring ring 431. This design makes it easy to remove and replace the mounting base 21 and the slide rail body 24 in the reserved slot 11 later.
