[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 6 As shown, a pole-mounted circuit breaker fixing structure includes a pole-mounted circuit breaker body 1 and a mounting base 2. Two mounting plates 3 are fixedly provided on the lower side of the pole-mounted circuit breaker body 1. The two mounting plates 3 are located inside the mounting base 2. Two rollers 4 are rotatably connected inside the two mounting plates 3. A double-ended screw handwheel 5 is rotatably connected inside the mounting base 2. Two symmetrically distributed connecting plates 6 are threaded on the outer surface of the double-ended screw handwheel 5.

[0028] An embedded plate 7 is fixedly installed on one side of each of the two connecting plates 6. A groove 8 is opened inside each of the two mounting seats 2. Two limiting plates 10 are rotatably installed inside the main body 1 of the pole-mounted circuit breaker. Two insert rods 11 for fixing the limiting plates 10 are snapped into one side of the mounting seat 2. An L-shaped positioning plate 12 for fixing the limiting plates 10 is slidably snapped into the upper side of each of the two limiting plates 10. Two slots 26 are opened at the bottom of the L-shaped positioning plate 12. One side of the L-shaped positioning plate 12 is snapped into the slot 26. Through the installation and use of the insert rods 11 and the L-shaped positioning plate 12, the installation of the two limiting plates 10 can be reinforced together, so that the two limiting plates 10 can stably and reliably limit the pole-mounted circuit breaker.

[0029] The upper side of the mounting base 2 is fixedly connected to a support recess 13 for positioning the main body 1 of the pole-mounted circuit breaker. Two symmetrically distributed movable pressure plates 14 are rotatably connected to one side of the support recess 13. Two rubber blocks 15 for supporting the main body 1 of the pole-mounted circuit breaker are fixedly installed on one side of each of the two movable pressure plates 14.

[0030] Two symmetrically distributed fixing blocks 21 are fixedly connected to the upper side of the mounting base 2. A rotating plate 22 is rotatably connected to the upper side of each fixing block 21. A sliding rod 23 for fixing the mounting plate 3 is slidably connected to one side of each rotating plate 22. One side of the sliding rod 23 passes through the rotating plate 22 and extends to the other side of the rotating plate 22. A connecting spring 24 is fixedly installed between each sliding rod 23 and the rotating plate 22. A circular groove 25 is opened on the upper side of each mounting plate 3. One side of the sliding rod 23 is engaged in the inside of the circular groove 25. By setting the sliding rod 23, as long as the elastic sliding rod 23 is pulled upward, and the rotating plate 22 is rotated, the sliding rod 23 is moved away from the mounting plate 3 to release the limit on the pole-mounted circuit breaker. Then, the embedded plate 7 and the limiting rotating plate 10 release the limit on the pole-mounted circuit breaker, so as to disassemble the entire pole-mounted circuit breaker.

[0031] A first semi-circular arc plate 16 is fixedly connected to the other side of the mounting base 2. A second semi-circular arc plate 18 is fixedly connected to one side of the first semi-circular arc plate 16 by two fastening bolts 17. Nuts 19 are threaded onto the outer surfaces of the two fastening bolts 17. Through the installation and use of the first semi-circular arc plate 16 and the second semi-circular arc plate 18, the two semi-circular arc plates can be fixed to the utility pole by using the fastening bolts 17 and nuts 19, so as to fix the entire pole-mounted circuit breaker. Two symmetrically distributed reinforcing support plates 20 are fixedly installed between the first semi-circular arc plate 16 and the mounting base 2.

[0032] Both mounting plates 3 have through-hole embedded grooves 27 inside, which are adapted to the embedded plates 7. One side of the embedded plate 7 is engaged with the interior of the mounting plate 3 through the embedded grooves 27.

[0033] The mounting base 2 is fixedly installed with a limiting rod 9. The interior of the two connecting plates 6 is slidably connected to the outer surface of the limiting rod 9. By setting the limiting rod 9, the movement trajectory of the two connecting plates 6 can be limited. In this way, the embedded plate 7 at the two connecting plates 6 can be moved and adjusted smoothly to position the pole-mounted circuit breaker, which is convenient to use. One side of the plug rod 11 passes through the mounting base 2 and extends into the interior of the mounting base 2.

[0034] The working principle of the pole-mounted circuit breaker fixing structure provided by this utility model is as follows:

[0035] By using the four rollers 4 at the two mounting plates 3, the pole-mounted circuit breaker body 1 can be pushed into the mounting base 2. Then, the two limiting rotating plates 10 are rotated into the mounting base 2. Subsequently, the two plug rods 11 are snapped into the inside of the limiting rotating plates 10. Then, the two L-shaped positioning plates 12 are inserted into the slots 26 to lock the position of the two limiting rotating plates 10 and position the pole-mounted circuit breaker body 1 at the two mounting plates 3. Next, the double-ended screw handwheel 5 is rotated. In this way, the double-ended screw handwheel 5 can drive the two connecting plates 6 to move relative to each other, so that the two embedded plates 7 are snapped into the embedded slots 27 of the two mounting plates 3 to form a fixed structure and further snap-fit ​​the pole-mounted circuit breaker. At this time, the pole-mounted circuit breaker can be conveniently installed or removed by snap-fitting without the need for bolt fixing, which improves the working efficiency of the pole-mounted circuit breaker fixing structure.

[0036] By installing the main body 1 of the pole-mounted circuit breaker onto the mounting base 2, the main body 1 of the pole-mounted circuit breaker can fit against the support recess 13. Then, rotate the two movable pressure plates 14 in sequence so that the rubber blocks 15 at the two movable pressure plates 14 can be embedded in one side of the pole-mounted circuit breaker, so that the support recess 13 and the movable pressure plates 14 can support the pole-mounted circuit breaker together, ensuring the stability of the pole-mounted circuit breaker during installation. Next, pull the two sliding rods 23 with connecting springs 24 upwards respectively, and then rotate the two rotating plates 22. In this way, the two elastic sliding rods 23 can be engaged into the circular grooves 25 of the two mounting plates 3, thereby limiting and fixing the entire pole-mounted circuit breaker.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
