[0002] As a key component of the power system, power distribution control equipment undertakes the core functions of receiving, distributing, controlling, and protecting electrical energy, and its performance directly affects the stable operation of electrical equipment and transmission lines. Among them, power distribution switch control equipment, especially complete switchgear, as the terminal directly facing users, integrates a variety of electrical components to meet the diversified needs of circuit control, protection, distribution, and monitoring.

[0003] In power distribution control equipment, the left and right guide rails typically refer to DIN rails or modular mounting rails. These provide a unified mounting platform, enabling various electrical components, such as circuit breakers, relays, and power modules, to be quickly and accurately fixed inside the equipment, ensuring installation precision and consistency. The rail design facilitates component disassembly and installation; components can be directly pushed in or pulled out during maintenance or upgrades without complex operations, improving maintenance efficiency.

[0004] However, existing guide rails have fixed dimensions and cannot accommodate components of different sizes and specifications. This necessitates providing guide rails of different sizes for different components within the power distribution control equipment, resulting in poor guide rail adaptability and increasing the complexity and cost of the equipment. Therefore, the applicant has developed a beneficial design to address the above problems and found a method to solve the poor guide rail adaptability. The technical solution described below arose from this background. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the above-mentioned background technology design and to provide a product with high adaptability, low usage cost, and low storage cost.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0014] Beneficial effects:

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention, by adjusting the distance between the movable plates on both sides of the guide rail, can flexibly adapt to electrical components of various sizes, improving the versatility and compatibility of the guide rail. Simultaneously, this design effectively reduces the user's initial investment in guide rail purchases and alleviates the pressure on manufacturers in guide rail inventory management, achieving improved cost-effectiveness. Furthermore, adjusting the movable plates requires no tools; simply pushing the linkage block easily disengages the connection, greatly facilitating installation, disassembly, or adjustment operations, resulting in exceptional ease of use. By inserting the limit rod into blind holes at different positions, not only can the distance between the movable plates be precisely adjusted, but accidental displacement of the movable plates during use can also be effectively prevented.

Several equally spaced blind holes 52 are provided on both sides of the second extensions 12. Limiting rods 3 are provided on both sides of the movable plate 2 and inserted into the blind holes 52. The limiting rods 3 are also magnetically attracted to the blind holes 52. A linkage block 4 is provided between two limiting rods 3 and slidably disposed in the linkage part 21. The linkage block 4 is also magnetically attracted to the linkage part 21.

[0029] By adjusting the distance between the movable plates 2 on both sides of the guide rail 1, various sizes of electrical components can be flexibly accommodated, improving the versatility and compatibility of the guide rail 1. Simultaneously, this design effectively reduces the user's initial investment in purchasing the guide rail 1 and alleviates the manufacturer's pressure on guide rail 1 inventory management, achieving improved cost-effectiveness. Furthermore, the adjustment of the movable plates 2 requires no tools; simply pushing the linkage block 4 easily disengages the connection, greatly facilitating installation, disassembly, or adjustment operations, highlighting its ease of use. By inserting the limiting rod 3 into the blind holes 52 at different positions, not only can the spacing of the movable plates 2 be precisely adjusted, but accidental displacement of the movable plates 2 during use can also be effectively prevented. At the same time, the attraction of the magnet 6 ensures a tight connection between the limiting rod 3 and the blind hole 52, further enhancing the stability of the connection. In summary, this technical solution has the advantages of high adaptability, low operating costs, and low storage costs.

[0030] It is worth mentioning that guide grooves 5 for the movable plate 2 are provided on both sides of the first extension 11 and the second extension 12.

[0031] It is worth mentioning that the guide groove 5 of the first extension 11 is provided with limiting through holes 5351 at both ends for the movement of the limiting rod 3. The surface of the first extension 11 is flush with the end face of the limiting rod 3. The limiting through holes 5351 limit the range of movement of the movable block. The flushness prevents the limiting rod 3 from interfering with the installation of electrical components.

[0032] It is worth mentioning that the blind hole 52 is located at the bottom of the guide groove 5 of the second extension 12, and the other end of the guide groove 5 of the second extension 12 is provided with a through hole 53 corresponding to the blind hole 52, and the through hole 53 is for the limit rod 3 to pass through.

[0033] It is worth mentioning that the inner sides of the guide rail 1 are provided with several reinforcing ribs 13, which are set on the back of each first extension 11 and second extension 12. The guide rail 1 is also provided with several mounting holes 14. The reinforcing ribs 13 strengthen the structural strength of the guide rail 1, and the guide rail 1 is connected and fixed to the cabinet through the mounting holes 14.

[0034] It is worth mentioning that the movable plate 2 has guide holes 22 on both sides for the limit rod 3 to pass through, and the end of the limit rod 3 is provided with a magnet 6. The movable plate 2 located in the first extension 11 is provided with a boss 23, which is flush with the first extension 11. The boss 23 abuts against the back buckle of the electrical component, thereby realizing the connection and fixation between the electrical component and the movable plate 2.

[0035] It is worth mentioning that the bottom of the linkage part 21 is provided with a sliding groove 24, and the two sides of the linkage block 4 are provided with guide sleeves 41, which are fitted into the guide hole 22. The guide sleeves 41 are connected and fixed to the limit rod 3 by screws. The linkage block 4 is provided with a slider 42, which is slidably disposed in the sliding groove 24. The linkage block 4 is provided with a magnet 6 and a pushing part 43. Through the design of the linkage part 21, an upward pushing force is applied to the pushing block, which can overcome the magnetic attraction and drive the linkage block 4 and the limit rod 3 to rise synchronously, so that the limit rod 3 is disengaged from the blind hole 52 and the through hole 53, thereby releasing the connection between the movable plate 2 and the second extension part 12. In addition, the contact state between the two ends of the sliding groove 24 and the slider 42 provides clear position indications for fixed connection and release respectively.

[0036] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
