While existing switchgear installation structures meet usage requirements to a certain extent, problems such as cumbersome operations and low efficiency during installation still exist, requiring improvement through innovative technologies.

[0003] Most existing power distribution cabinet installation structures employ traditional fixed installation methods, including securing the cabinet to its location using bolts, brackets, or metal frames. These mechanical structures primarily ensure the stability and safety of the cabinet through metal connectors such as bolts and washers. The technical principle of this structure is based on mechanical design to ensure that the cabinet will not shift or be damaged by external forces during operation. Bolt fixing is currently the most common installation method, simple, easy to implement, and relatively inexpensive. However, this structure also has certain limitations, mainly in that installation is cumbersome, disassembly is difficult, and installation and commissioning require a considerable amount of time.

[0004] Although existing technologies have made some progress in the installation of distribution cabinets, in practical applications, especially during reinstallation, the process remains complex and inconvenient. Current installation methods require significant manual labor, and each installation or disassembly necessitates precise adjustments and fixation, which is time-consuming. Furthermore, installers must ensure accurate alignment of each connecting component, which is inefficient and prone to errors, especially for large-scale installations and maintenance. Therefore, simplifying the installation process, improving efficiency, and reducing unnecessary steps are problems that need to be addressed. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-5This utility model provides an embodiment of an installation structure for a high and low voltage distribution cabinet, including a fixing plate 1. A connecting block 2 is attached to the upper surface of the fixing plate 1. The fixing plate 1 serves as the basic load-bearing component of the entire installation structure, providing stable support. A quick-release assembly is provided on the inner wall of the fixing plate 1. The quick-release assembly includes a locking block 7. The outer wall of the locking block 7 is fixedly connected to the inner wall of the fixing plate 1. The fixed connection between the locking block 7 and the fixing plate 1 ensures that the quick-release assembly is not easily loosened under stress. A quick-release post 4 is slidably connected to the inner wall of the locking block 7, and the inner wall of the quick-release post 4 is threadedly connected to... Threaded post 5, with spring 2 17 fixedly connected to one end. The fixed connection between threaded post 5 and spring 2 17 can achieve elastic buffering when under force, enhancing the limiting and resetting effect. Limiting post 8 is fixedly connected to one end of spring 2 17. A ball 1 9 is slidably connected to the outer wall of limiting post 8. The sliding cooperation between limiting post 8 and ball 1 9 makes the limiting function more flexible. A ball 2 10 is slidably connected to the outer wall of ball 1 9. Limiting post 8 is slidably connected to the inner wall of quick release post 4, so that it can move smoothly and transmit locking force. Multiple balls 1 9 are provided on the inner wall of quick release post 4.

[0020] Specifically, the fixing plate 1 and connecting block 2 ensure the overall rigidity and foundation stability of the distribution cabinet installation structure; the locking block 7 and quick-release column 4 ensure the positional stability and reliability of the quick-release components during operation, support rapid assembly and disassembly, and improve shock resistance and long-term durability; the threaded column 5, spring 17, limit column 8, ball 9 and ball 10 provide continuous preload and elastic buffer in the structure, making the locking process stable and reliable, and reducing wear on components caused by frequent operation.

[0021] Reference Figures 1-5A shock-absorbing block 6 is fixedly connected to the upper surface of the connecting block 2. The connecting block 2 and the shock-absorbing block 6 interact to enhance the vibration resistance of the structure. Multiple screws 16 are threaded onto the inner wall of the shock-absorbing block 6, securing it and ensuring it does not loosen during equipment operation, thus improving overall stability. Multiple screws 14 are also threaded onto the inner wall of the shock-absorbing block 6, providing fixation between the shock-absorbing block 6 and the distribution cabinet base. Bolts 15 are threaded onto the outer walls of all screws 14. A connecting post 13 is threaded onto the inner wall of the shock-absorbing block 6, and an upper damper 18 is threaded onto the outer wall of the connecting post 13. The connecting post 13 supports the upper damper 18, providing a buffering function under external forces. Spring 12 is fixedly connected to the lower surface of the damper 18. The upper damper 18 cooperates with spring 12 to disperse external impact force and reduce the impact on the structure. Lower damper 11 is fixedly connected to the upper surface of the shock absorber block 6. Lower damper 11 is used to form a two-way buffer system with spring 12 to enhance the overall shock absorption effect. Spring 12 and connecting column 13 are fixedly connected to the upper surface of lower damper 11. Distribution cabinet base 3 is fixedly connected to the upper surface of the shock absorber block 6. The shock absorber block 6 cooperates with distribution cabinet base 3 to provide a solid support foundation for the entire cabinet. Screw 14 is threadedly connected to the inner wall of distribution cabinet base 3. Quick release column 4 is slidably connected to the inner wall of connecting block 2. Ball 2 10 is slidably connected to the inner wall of locking block 7.

[0022] Specifically, connecting block 2 and anti-vibration block 6 provide overall support and shock resistance; screw 14, screw 16 and bolt 15 enhance structural reinforcement and improve long-term operational durability; connecting column 13, upper damper 18, lower damper 11 and spring 12 absorb vibration and provide buffering, improving structural stability; distribution cabinet base 3 and anti-vibration block 6 enhance bottom support and impact resistance; quick-release column 4, connecting block 2, ball 10 and locking block 7 ensure the safety and stability of quick installation and disassembly. The overall design enables the distribution cabinet to be installed quickly, stably, and shock-resistant, while ensuring long-term operational reliability and convenient maintenance.

[0023] Working Principle: When the distribution cabinet needs to be installed, the quick-release assembly on the inner wall of the fixing plate 1 can achieve rapid fixation. The operator pushes the quick-release pin 4 along the inner wall of the connecting block 2 into the locking block 7. When the threaded pin 5 inside the quick-release pin 4 moves forward, it causes the limiting pin 8 to move. During the movement, the limiting pin 8 applies a squeezing force to the multiple balls 9 on the outer wall. The balls 9 are forced to expand outward, pushing the second ball 10 into the groove on the inner wall of the locking block 7, thereby reliably locking the quick-release pin 4. With the help of the internal spring 17 providing continuous preload, the limiting pin 8 and the quick-release pin 4 form a stable lock. After installation, no additional screws or tools are required to ensure that the distribution cabinet components are securely fixed to the fixing plate 1. The components are now firmly integrated to ensure overall stability and shock resistance during operation. When disassembly is required, the operator only needs to pull or rotate the quick-release column 4 backward. The internal threaded column 5 drives the limiting column 8 to gradually retract. The ball 9, which was originally under pressure, loses its axial pressure and automatically retracts into the cavity of the quick-release column 4. The ball 10 also exits from the slot of the locking block 7. Under the rebound force of the spring 17, the quick-release assembly is unlocked, and the quick-release column 4 can be smoothly pulled out from the locking block 7, thereby quickly releasing the components fixed on the fixing plate 1. The whole process does not require the use of screwdrivers or other tools, avoiding component wear caused by frequent disassembly and assembly, and improving the convenience of maintenance and repair of the distribution cabinet.

[0024] In addition, a shock-absorbing block 6 is fixedly installed on the upper surface of the connecting block 2. The internal screws 16 and 14, together with the bolts 15, form a reliable fastening effect. The connecting column 13 inside the shock-absorbing block 6 works in conjunction with the upper damper 18, the lower damper 11, and the spring 12 to effectively absorb external vibrations and shocks during equipment operation, reducing the risk of uneven stress on electrical components. At the same time, the upper surface of the shock-absorbing block 6 is fixedly connected to the distribution cabinet base 3. The screws 14 on the inner wall of the base 3 ensure the stability and durability of the overall structure. While the quick-release assembly completes the rapid fixing of electrical components, the shock-absorbing and damping mechanism ensures the stability and reliability of the equipment during long-term operation. Thus, the entire installation structure has both efficient assembly and disassembly functions and anti-vibration and stability performance.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
