[0020] The protective shielding assembly 5 includes a protective top plate 7, and the protective top plate 7 is fixedly installed on the top of the support frame 4. The top of the protective top plate 7 is symmetrically provided with an inclined surface structure. Positioning frames 8 are fixedly installed at both ends of the bottom of the protective top plate 7. A protective support plate 9 is installed inside the positioning frame 8 and movably penetrates therethrough. The tops of the two protective support plates 9 are both inclined surface structures. The two protective support plates 9 are connected to the adjustment assembly 6. A baffle bar 10 is fixedly installed on one side of the two protective support plates 9 that are close to each other. Three positioning slide bars 11 are evenly and movably installed inside the bottom end of the positioning frame 8, and one end of the positioning slide bar 11 is fixedly connected to the baffle bar 10, and a circular limit block 12 is fixedly installed on the other end of the positioning slide bar 11.

[0021] The adjustment assembly 6 includes a bar frame 13, and the bar frame 13 is fixedly installed on the side of the support frame 4 away from the column-mounted circuit breaker body 1, an adjustment disk 14 is arranged on the top of the bar frame 13, a threaded rod 15 is rotatably installed inside the bar frame 13, and the top of the threaded rod 15 is movably penetrated through the bar frame 13 and fixedly connected to the adjustment disk 14, a threaded sleeve 16 is threadedly installed inside the bar frame 13 and on the outer side of the threaded rod 15, and a positioning slide groove 22 is penetrated and opened on the side of the bar frame 13 away from the column-mounted circuit breaker body 1, and the bottom end of the inner part of the positioning slide groove 22 is movably installed.

[0022] During use, through the interaction of the pole-mounted circuit breaker body 1, the supporting base plate 2, the supporting frame 4, the protective shielding assembly 5 and the adjusting assembly 6, the primary and secondary fusion type pole-mounted circuit breaker can be used to achieve better protection effect, avoid direct exposure to the outside, reduce the influence of sunlight and rain on it, and increase its service life, so as to achieve better practicality.

[0023] Working principle: When working, first rotate the adjusting disk 14 to drive the threaded rod 15 to rotate, the threaded rod 15 drives the threaded sleeve 16 to move upward, and the threaded sleeve 16 drives the positioning slider 23 to slide inside the positioning slide groove 22, which can ensure that the threaded sleeve 16 achieves better stability when moving.

At this time, the two protective support plates 9 move away from each other, and the protective support plate 9 drives the baffle bar 10 to move. The baffle 10 drives the positioning slide bar 11 to slide inside the bottom end of the positioning frame 8, which can ensure that the baffle 10 achieves better stability when moving. After the baffle 10 moves to contact the positioning frame 8, the two protective support plates 9 are fully unfolded, and then the rotation of the adjustment disk 14 is stopped. Then, during use, the protective top plate 7 and the two protective support plates 9 interact with each other to form a protective shielding directly above the pole-mounted circuit breaker body 1, so that the primary and secondary fusion pole-mounted circuit breaker can achieve better protection during use, avoid direct exposure to the outside, reduce the impact of sunlight and rain on it, and increase its service life, thereby achieving better practicality.
