[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] First Embodiment Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of the first embodiment of the installation structure of a secondary integrated pole-mounted circuit breaker provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the limiting component. Figure 3 for Figure 1 The diagram shows the structure of the snap-fit ​​assembly.

[0018] An installation structure for a secondary integrated pole-mounted circuit breaker includes: a mounting plate 1; A limiting component 2 is disposed on the front side of the mounting plate 1. The limiting component 2 includes a mounting frame 21, a sliding rod 22, a spring 23, a snap-fit ​​plate 24, and a pressing plate 25. The mounting frame 21 is fixedly installed on the front side of the mounting plate 1. The sliding rod 22 is fixedly installed on the inner side of the mounting frame 21. The spring 23 is sleeved on the outer side of the sliding rod 22. The snap-fit ​​plates 24 are respectively disposed at both ends of the spring 23 and slidably connected to the outer side of the sliding rod 22. The pressing plate 25 is fixedly installed on one side of the snap-fit ​​plate 24. The snap-fit ​​component 3 is disposed on the front side of the limiting component 2. The snap-fit ​​component 3 includes a fixing plate 31, a groove 32 and a snap-fit ​​groove 33. The groove 32 is formed on the back side of the fixing plate 31 and the snap-fit ​​groove 33 is formed on one side of the inner side of the groove 32. The circuit breaker body 4 is disposed on the front side of the snap-fit ​​assembly 3.

[0019] Mounting holes 11 are provided on the interior of all four sides of the mounting plate 1.

[0020] With the mounting hole 11 provided, when in use, the mounting screw is passed through the mounting hole 11, and then the mounting screw is threaded to the mounting position to install the mounting plate 1.

[0021] The snap-fit ​​plate 24 snaps into the inner side of the snap-fit ​​groove 33, and the pressing plate 25 is slidably connected to the inside of the side of the mounting frame 21.

[0022] The snap-fit ​​plate 24 is snapped into the inner side of the snap-fit ​​groove 33, which serves to limit the movement between the mounting frame 21 and the fixing plate 31 during use.

[0023] The fixing plate 31 is fixedly installed on the back of the circuit breaker body 4.

[0024] The working principle of the installation structure of the secondary integrated pole-mounted circuit breaker provided by this utility model is as follows: First, use bolts to fix the mounting plate 1 to the preset installation position on the column through the mounting holes 11 around the mounting plate 1, ensuring that the mounting plate 1 is stable and the front faces the operation direction; When installing the circuit breaker body 4, press the two pressing plates 25 of the limiting component 2 inward with both hands at the same time. The pressing plates 25 drive the snap-fit ​​plates 24 to slide along the slide rod 22 towards the middle, compressing the spring 23 to retract it. At this time, the gap between the two snap-fit ​​plates 24 is reduced. Align the snap-fit ​​component 3 on the back of the circuit breaker body 4 with the mounting frame 21 so that the snap-fit ​​plates 24 are embedded in the groove 32 of the fixing plate 31. Then release the pressing plates 25. The spring 23 returns to its original position and pushes the two snap-fit ​​plates 24 to slide to both sides until the snap-fit ​​plates 24 are snapped into the snap-fit ​​groove 33 on the inner side of the groove 32, thus completing the quick fixing of the circuit breaker. The cooperation between the snap-fit ​​plates 24 and the snap-fit ​​groove 33 ensures that the circuit breaker will not shift back and forth or left and right, achieving a stable installation. To disassemble the circuit breaker body 4, press the two pressing plates 25 inward again to disengage the snap-fit ​​plate 24 from the snap-fit ​​groove 33 and retract it towards the center. At this time, the circuit breaker body 4 can be pulled outward to disengage the groove 32 of the snap-fit ​​assembly 3 from the mounting frame 21, thus completing the disassembly. The entire process does not require rotating any threaded parts, making the operation efficient and convenient.

[0025] Compared with related technologies, the installation structure of the secondary integrated pole-mounted circuit breaker provided by this utility model has the following beneficial effects: With the setting of limit component 2 and snap-fit ​​component 3, when installing the circuit breaker body 4, simply press the pressing plate 25 inward to drive the snap-fit ​​plate 24 to retract. After aligning the groove 32 of the snap-fit ​​component 3 with the mounting frame 21, release the pressing plate 25, and the spring 23 will push the snap-fit ​​plate 24 into the snap-fit ​​groove 33 to complete the fixation. When disassembling, press the pressing plate 25 again to make the snap-fit ​​plate 24 disengage from the snap-fit ​​groove 33, and the circuit breaker can be pulled out directly. The operation is convenient and quick, increasing the efficiency of disassembling and installing the circuit breaker body 4.

[0026] Second Embodiment Please refer to the following: Figure 4 , Figure 5 and Figure 6 Based on the installation structure of a secondary integrated pole-mounted circuit breaker provided in the first embodiment of this application, the second embodiment of this application proposes another installation structure for a secondary integrated pole-mounted circuit breaker. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0027] Specifically, the difference in the installation structure of the secondary fusion pole-mounted circuit breaker provided in the second embodiment of this application is that, in the installation structure of the secondary fusion pole-mounted circuit breaker, the back of the snap-fit ​​component 3 is provided with an abutment component 5.

[0028] The abutment component 5 includes a spring telescopic rod 51, a limiting block 52, and a limiting groove 53. The spring telescopic rod 51 is fixedly installed on the inner side of the mounting frame 21, the limiting block 52 is fixedly installed on one end of the spring telescopic rod 51, and the limiting groove 53 is opened on the back of the fixing plate 3.

[0029] The limiting block 52 is engaged with the inner side of the limiting groove 53.

[0030] By locking the limit block 52 onto the inner side of the limit groove 53, the circuit breaker body 4 can be limited to prevent it from shaking.

[0031] The working principle of the installation structure of the secondary integrated pole-mounted circuit breaker provided by this utility model is as follows: When disassembling, after the user presses down on the two pressing plates 25, the two snap-fit ​​plates 24 will move out from the inner side of the two snap-fit ​​slots 33. At this time, the spring telescopic rod 51 extends, thereby pushing the fixing plate 31 away from the mounting frame 21, and making the snap-fit ​​plates 24 away from the snap-fit ​​slots 33.

[0032] Compared with related technologies, the installation structure of the secondary integrated pole-mounted circuit breaker provided by this utility model has the following beneficial effects: By setting the abutment component 5, when the user presses the two pressing plates 25 during disassembly, the fixing plate 31 will move away from the mounting frame 21, thereby moving the snap plate 24 away from the snap groove 33, which further increases the efficiency of disassembling the circuit breaker body 4.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
