[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 Figure 1-7 As shown, a primary and secondary integrated pole-mounted circuit breaker includes a mounting frame 1. The mounting frame 1 has a mounting structure 2. The mounting structure 2 includes two positioning rods 201 fixedly connected to the mounting frame 1. Mounting frames 202 are detachably connected to the positioning rods 201. Circuit breaker bodies 5 are mounted on the two mounting frames 202. Two sliding plates 204 are slidably connected inside the mounting frame 1. The sliding plates 204 are slidably connected to the positioning rods 201. Mounting blocks 203 are fixedly connected to the sliding plates 204 and slidably connected to the positioning rods 201. The two mounting blocks 203 are respectively engaged with the two mounting frames 202. A lead screw 205 is rotatably connected inside the mounting frame 1. The sliding plates 204 are threadedly connected to the lead screw 205, and the threads at both ends of the lead screw 205 have opposite directions.

[0026] As a technical optimization of this utility model, the mounting frame 202 has a concave cross-section, the end of the lead screw 205 is provided with an inner hexagonal groove, a guide post 206 is fixedly connected to the sliding plate 204, the guide post 206 is slidably connected to the mounting frame 1, the mounting block 203 has a trapezoidal cross-section, the length of the lead screw 205 is the same as the width of the mounting frame 1, a first clamp 6 is installed on the mounting frame 1, and a second clamp 7 is installed on the first clamp 6 by bolt and nut cooperation. The lead screw 205 simultaneously drives the two mounting blocks 203 to engage with the mounting frame 202, which facilitates the quick installation of the circuit breaker body 5 and improves the installation efficiency.

[0027] As a technical optimization of this utility model, a protective structure 4 is provided on the lead screw 205. The protective structure 4 includes a protective block 401 slidably connected within the lead screw 205. The protective block 401 is hexagonal in shape. A spring 402 is connected between the protective block 401 and the lead screw 205. One end of the spring 402 is fixedly connected to the protective block 401, and the other end is fixedly connected to the lead screw 205. Two anti-detachment blocks 403 are fixedly connected to the protective block 401. The anti-detachment blocks 403 are slidably connected to the lead screw 205. Simultaneously, when the mounting frame 202 at the bottom of the circuit breaker body 5 is inserted into the positioning rod 201, the four positioning plates 301 position the circuit breaker body 5, thus ensuring the mounting frame 202 is securely attached to the lead screw 205. The mounting slot on the frame 202 can be aligned with the mounting block 203. At this time, the protective block 401 is pressed by pressing the hex wrench. When the protective block 401 slides into the screw 205, it drives the anti-disengagement block 403 to slide. The anti-disengagement block 403 can prevent the protective block 401 from slipping out of the screw 205. At the same time, the spring 402 contracts. When it is inserted into the screw 205, the screw 205 rotates. When the screw 205 rotates, the thread drives the two sliding plates 204 to slide towards each other. The sliding plates 204 will drive the guide post 206 to slide and engage with the mounting bracket 1. The guide post 206 makes the sliding plate 204 slide more smoothly. At the same time, the sliding plate 204 drives the mounting block 203 to engage with the mounting frame 202. At this time, the installation of the circuit breaker body 5 is completed.

[0028] As a technical optimization of this utility model, the mounting frame 1 is provided with a positioning structure 3. The positioning structure 3 includes four positioning plates 301 fixedly connected to the mounting frame 1. A guide plate 302 is fixedly connected to the positioning plate 301. The positioning plate 301 is perpendicular to the mounting frame 1, and the guide plate 302 is inclined. The inclined arrangement of the guide plate 302 can play a guiding role when placing the circuit breaker body 5. At the same time, when the mounting frame 202 at the bottom of the circuit breaker body 5 is inserted with the positioning rod 201, the four positioning plates 301 play a positioning role for the circuit breaker body 5, so that the mounting groove on the mounting frame 202 can be aligned with the mounting block 203.

[0029] In use, when installing the circuit breaker, the mounting frame 1 is first fixed to the column using bolts and nuts in conjunction with the first clamp 6 and the second clamp 7. Then, the circuit breaker body 5 is hoisted to the designated height using hoisting equipment, positioning it above the mounting frame 1. Next, the circuit breaker body 5 is moved downwards along the guide plate 302 using the hoisting equipment. Since the guide plate 302 is inclined, it provides guidance when placing the circuit breaker body 5. Simultaneously, after the mounting frame 202 at the bottom of the circuit breaker body 5 is inserted with the positioning rod 201, the four positioning plates 301 position the circuit breaker body 5, ensuring that the mounting groove on the mounting frame 202 aligns with the mounting block 203. At this point, the protective block 401 is pressed down using an Allen wrench. When the protective block 401 slides into the lead screw 205, it causes the anti-detachment block 403 to slide. The anti-detachment block 403 prevents the protective block 401 from slipping out of the lead screw 205. At the same time, the spring 402 contracts. After being inserted into the lead screw 205, the lead screw 205 rotates. When the lead screw 205 rotates, the thread drives the two sliding plates 204 to slide towards each other. The sliding plates 204 drive the guide post 206 to slide and engage with the mounting frame 1. The guide post 206 makes the sliding plates 204 slide more smoothly. At the same time, the sliding plates 204 drive the mounting block 203 to engage with the mounting frame 202. At this time, the installation of the circuit breaker body 5 is completed. The lead screw 205 drives the two mounting blocks 203 to engage with the mounting frame 202, which facilitates the quick installation of the circuit breaker body 5 and improves the installation efficiency.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
