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.

[0023] Please see Figures 1-6 This utility model provides a technical solution: a gear set bracket for a nylon-cased circuit breaker, comprising a first circuit breaker mounting housing 1, a second circuit breaker mounting housing 2 mounted on one side of the first circuit breaker mounting housing 1, and a gear set and a bracket set installed inside the second circuit breaker mounting housing 2; wherein the gear set includes a drive motor 3 mounted on the inner wall of the second circuit breaker mounting housing 2, the outer wall of the drive motor 3 being fixedly connected to the inner wall of the second circuit breaker mounting housing 2, the fixed connection improving the installation stability of the drive motor 3, reducing transmission errors and malfunctions caused by the drive motor 3 shaking due to external factors, and extending the service life of the drive motor 3 and the entire gear set; the output end of the drive motor 3 is connected to a screw rod 4, the drive motor 3 serving as a power source, directly driving the screw rod 4 to rotate through the output end, converting electrical energy into mechanical energy, and supplying power to the circuit breaker. The entire gear set provides power. The bottom end of the helical rod 4 is meshed with the first gear 5. The helical rod 4 transmits power to the first gear 5 by rotating, causing the first gear 5 to rotate. The outer wall of one side of the first gear 5 is meshed with the second gear 6, the outer wall of the second gear 6 is meshed with the third gear 7, and the outer wall of the third gear 7 is meshed with the trigger wheel 13. Through the meshing between the first gear 5, the second gear 6, and the third gear 7, power and motion are transmitted sequentially. The first gear 5 transmits power to the second gear 6, the second gear 6 transmits power to the third gear 7, and finally the third gear 7 transmits power to the trigger wheel 13, realizing the step-by-step transmission of power and the conversion of motion. The gear meshing transmission has the advantages of accurate transmission ratio, high transmission efficiency, and compact structure, which can ensure that the trigger wheel 13 accurately triggers the component action.

[0024] See Figure 2 , Figure 3 , Figure 6The bracket assembly includes a first mounting bracket 8 installed near the output end of the drive motor 3. The first mounting bracket 8 fixes the entire bracket assembly near the output end of the drive motor 3, providing support for the gear set. A first rotating shaft 9 is installed on one outer wall of the first mounting bracket 8. A second mounting bracket 10 is fixedly connected to the end of the first rotating shaft 9 away from the first mounting bracket 8. The connection between the first rotating shaft 9 and the second mounting bracket 10 enhances the stability of the bracket assembly. A second rotating shaft 11 and a third rotating shaft 12 are also installed on one outer wall of the first mounting bracket 8. The end of the second rotating shaft 11 away from the first mounting bracket 8 is fixedly connected to the second mounting bracket 10, and the end of the third rotating shaft 12 away from the first mounting bracket 8 is fixedly connected to the second mounting bracket 10. One end is fixedly connected to the second mounting bracket 10. The outer wall of the first rotating shaft 9 is rotatably connected to the inner wall of the first gear 5. The first rotating shaft 9 ensures that the first gear 5 can rotate around its own central axis. The outer wall of the second rotating shaft 11 is rotatably connected to the inner wall of the second gear 6. The second rotating shaft 11 connects the first mounting bracket 8 and the second mounting bracket 10, and at the same time provides rotational support for the second gear 6, ensuring that the second gear 6 can rotate normally. The outer wall of the third rotating shaft 12 is rotatably connected to the inner wall of the third gear 7. The third rotating shaft 12 also connects the first mounting bracket 8 and the second mounting bracket 10, and at the same time provides rotational support for the third gear 7, ensuring that the third gear 7 can transmit power to the trigger wheel 13.

[0025] See Figure 4 , Figure 5 A first protruding gear is installed on one side of the outer wall of the first gear 5. When the first gear 5 rotates, it drives the first protruding gear to rotate synchronously. The first gear 5 is meshed with the second gear 6 through the first protruding gear. The first protruding gear meshes with the second gear 6 and transmits power to the second gear 6, causing the second gear 6 to rotate around its own center. A second protruding gear is installed on one side of the outer wall of the second gear 6. When the second gear 6 rotates, it drives the second protruding gear to rotate synchronously. The second gear 6 is meshed with the third gear 7 through the second protruding gear. When the second protruding gear rotates, the third gear 7 will rotate around its own center.

[0026] See Figure 1 , Figure 2 The first circuit breaker mounting housing 1 and the second circuit breaker mounting housing 2 are fixedly connected. The materials of the first circuit breaker mounting housing 1 and the second circuit breaker mounting housing 2 are nylon materials. Nylon has good wear resistance, corrosion resistance and insulation properties, and is suitable for making the first circuit breaker mounting housing 1 and the second circuit breaker mounting housing 2. Nylon materials have high strength and rigidity, and can withstand a certain amount of external impact, protecting the internal components from damage.

[0027] Working principle: The start of the drive motor 3 drives the screw rod 4 to rotate synchronously. The rotation of the screw rod 4 drives the first gear 5 to rotate on the outer wall of the first rotating shaft 9. The rotation of the first gear 5 will synchronously drive the meshing second gear 6 to rotate on the outer wall of the second rotating shaft 11. The rotation of the second gear 6 drives the third gear 7 to rotate around the third rotating shaft 12. The rotation of the third gear 7 triggers the trigger wheel 13. The support group keeps the center distance of the gear set fixed and is not affected by the size change of the nylon shell.
