[0024] 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.

[0025] Please see Figures 1-5 The present invention provides a quick-release internal electrical installation frame for a power switch cabinet, comprising a switch cabinet body 1 and a door panel 2.

[0026] Reference Figures 1-4As shown, a door panel 2 is hinged to one side of the switch cabinet body 1. A mounting frame body 3 is installed inside the switch cabinet body 1. Quick-release structures 4 are evenly fixed inside the mounting frame body 3. Each quick-release structure 4 includes a fixing plate 401 evenly fixed inside the mounting frame body 3. Guide grooves 402 are evenly formed at the top of the fixing plate 401. Guide rods 403 are fixed inside the guide grooves 402. Mounting seats 404 are provided at the top of each fixing plate 401. Snap-fit ​​holes 405 are evenly formed inside the mounting frame body 3 on both sides of the mounting seat 404. Reserved grooves 406 are formed on both sides of the mounting seat 404. Snap-fit ​​rods 406 are installed inside the reserved grooves 406. 7. A return spring 408 is fixed on one side of the snap-fit ​​rod 407. The fixing plates 401 are evenly distributed inside the mounting frame body 3. The guide grooves 402 are symmetrically distributed at the top of the fixing plates 401. The bottom of the mounting base 404 extends into the interior of the guide grooves 402. The guide rod 403 passes through the bottom of the mounting base 404. The snap-fit ​​holes 405 are evenly distributed inside the mounting frame body 3. The side of the return spring 408 away from the snap-fit ​​rod 407 is fixedly connected to one side inside the reserved groove 406. The snap-fit ​​rod 407 is set inside the snap-fit ​​hole 405. The snap-fit ​​rod 407 and the mounting frame body 3 form a snap-fit ​​structure through the snap-fit ​​hole 405.

[0027] In order to facilitate quick and easy disassembly and assembly of the internal electrical components during the operation and use of the power switchgear, a quick-release structure 4 is provided. This allows the bottom of the mounting base 404 at the top of the fixing plate 401 to extend into the guide groove 402, with the guide rod 403 passing through its bottom to guide the mounting base 404. This allows the mounting base 404 to slide on the top of the fixing plate 401. The mounting base 404 is positioned on the top of the fixing plate 401 by a locking structure formed by the locking rod 407 and the locking hole 405, ensuring the mounting base 404 is firmly fixed. The top of the fixed plate 401 is not prone to positional displacement. In order to facilitate the disassembly and assembly of electronic components at the top of the mounting base 404, the mounting base 404 is pulled outward, causing the locking rod 407 to be squeezed and moved into the interior of the reserved slot 406. When the locking rod 407 moves to the side of another set of locking holes 405, the return spring 408 pushes the locking rod 407 into the interior of the reserved slot 406, thereby further positioning the mounting base 404. This makes it less likely for the mounting base 404 to shift position when disassembling and assembling electronic components, thus greatly increasing the practicality of the device.

[0028] Reference Figure 1 , Figure 2 and Figure 5As shown, both ends of the mounting frame body 3 are fixed with disassembly and assembly structures 5. The disassembly and assembly structure 5 includes fixing blocks 501 that are evenly fixed to both ends of the mounting frame body 3 and sliding grooves 502 that are evenly penetrated through both ends of the mounting frame body 3. Fastening bolts 503 are evenly provided on the inner wall of the switch cabinet body 1 on one side of the fixing block 501. The fixing block 501 and the switch cabinet body 1 are slidably connected by the fastening bolts 503. The fastening bolts 503 all extend into the interior of the switch cabinet body 1.

[0029] During prolonged use, the mounting bracket body 3 may be damaged, requiring disassembly and maintenance. The disassembly and assembly structure 5 addresses this by guiding the mounting bracket body 3 through the placement of the fixing block 501 within the sliding groove 502. When the mounting bracket body 3 is placed inside the switch cabinet body 1, the fastening bolts 503 are rotated into the switch cabinet body 1 to position the mounting bracket body 3. This prevents the mounting bracket body 3 from shifting within the switch cabinet body 1, facilitating disassembly, assembly, maintenance, and use, thus greatly increasing the practicality of the device.

[0030] Although the present invention 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 invention should be included within the protection scope of the present invention.
