Through this circuit breaker, the load current, overload current, and short-circuit current in the power system can be controlled and protected. Generally, for electrostatic discharge (ESD) protection, the circuit breaker is installed internally to provide ESD protection.

[0004] Existing circuit breakers have the following defects in practical use:

[0005] When circuit breakers need to be inspected, the existing circuit breakers are mostly fixedly installed with the anti-static housing, and the circuit breakers are located inside the anti-static housing, making it inconvenient for workers to disassemble the circuit breakers, which makes manual disassembly of the circuit breakers quite cumbersome. Utility Model Content

[0006] In the existing technology, when it is necessary to maintain the circuit breaker, the installation method between the existing circuit breaker and the anti-static housing is mostly fixed, and the circuit breaker is located inside the anti-static housing, which makes it inconvenient for workers to disassemble the circuit breaker. This results in a cumbersome technical problem when manually disassembling the circuit breaker. This utility model provides a primary and secondary integrated pole-mounted circuit breaker with anti-static function.

[0007] The technical solution adopted by this utility model is: a primary and secondary integrated pole-mounted circuit breaker with anti-static function, including a circuit breaker, an anti-static housing, and an anti-static sealing cover. A fixing mechanism is provided inside the anti-static housing. The circuit breaker is disposed on the upper side of the fixing mechanism. The fixing mechanism includes a fixing plate, a pull-out plate, and a fixing rod. The fixing rod is fixedly installed on the upper side of the pull-out plate, and the fixing plate is plugged into the fixing rod. An installation cavity is opened in the pull-out plate. Four L-shaped sliding plates are slidably installed in the installation cavity. A toothed plate is fixedly installed on one side of the L-shaped sliding plate. A rotating shaft is rotatably installed in the installation cavity. Gears are fixedly installed on the periphery of the rotating shaft. The four toothed plates mesh with two of the gears respectively. The L-shaped sliding plates correspond to the fixing plate and the fixing rod.

[0008] Furthermore, a rotating rod is rotatably installed inside the mounting cavity, and worm gears are fixedly installed on both sides of the rotating rod. Turbines are fixedly installed on the sides of both rotating shafts, and the worm gears mesh with the turbines.

[0009] Furthermore, four slide rails are fixedly installed at the bottom of the inner wall of the mounting cavity, and the four L-shaped slide plates are slidably connected to the four slide rails respectively.

[0010] Furthermore, the circuit breaker is fixedly installed on the upper side of the fixing plate, and there are four fixing rods, which are respectively located at the four corners of the upper side of the pull-out plate.

[0011] Furthermore, one end of the L-shaped slide plate is provided with a snap-fit ​​groove, and one end of the L-shaped slide plate is inserted into the upper periphery of the fixed rod through the snap-fit ​​groove.

[0012] Furthermore, a rotating knob is rotatably mounted on one side of the pull-out plate, and the rotating knob is fixedly connected to the rotating rod. An insertion limiting groove is provided on one side of the rotating knob. The antistatic sealing cover is disposed on one side of the antistatic housing, and a groove is provided on one side of the antistatic sealing cover. An insertion limiting block is provided in the groove, and the insertion limiting block corresponds to the insertion limiting groove.

[0013] Furthermore, a limiting groove is provided at the bottom of the inner wall of the antistatic housing, and limiting plates are fixedly installed on both sides of the inner wall of the antistatic housing. The two ends of the pull plate are slidably installed between the limiting plates and the bottom of the inner wall of the antistatic housing, respectively. A limiting slider is fixedly installed on the lower side of the pull plate, and the limiting slider is slidably installed in the limiting groove.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model, through a fixing mechanism, allows workers to easily and quickly remove the circuit breaker from the anti-static housing when maintenance is required, and allows workers to easily and quickly install the circuit breaker back into the anti-static housing after maintenance, thereby improving the convenience of maintenance for workers when repairing circuit breakers.

[0016] 2. Secondly, this utility model utilizes a worm gear and a turbine, which, through their self-locking characteristics, can lock the rotating shaft and gear, ensuring the stability of the L-shaped sliding plate when limiting the fixed plate, thereby enabling the circuit breaker to be stably installed in the anti-static housing.

[0017] 3. This utility model also uses a plug-in limiting block and a plug-in limiting groove to push the pull-out plate into the anti-static housing. When the anti-static sealing cover is fixed on one side of the anti-static housing, the plug-in limiting block can be inserted into the plug-in limiting groove to limit the rotation knob and worm gear, thereby further improving the stability of the L-shaped sliding plate when limiting the fixed plate.

[0027] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a primary and secondary integrated pole-mounted circuit breaker with anti-static function.

[0028] The specific technical solution includes a circuit breaker 1, an anti-static housing 2, and an anti-static sealing cover 3. A fixing mechanism 4 is installed inside the anti-static housing 2. The circuit breaker 1 is mounted on the upper side of the fixing mechanism 4. The fixing mechanism 4 includes a fixing plate 5, a pull-out plate 8, and a fixing rod 9. The fixing rod 9 is fixedly installed on the upper side of the pull-out plate 8, and the fixing plate 5 is plugged into the fixing rod 9. A mounting cavity 10 is opened inside the pull-out plate 8. Four L-shaped sliding plates 12 are slidably installed inside the mounting cavity 10. A toothed plate 13 is fixedly installed on one side of each L-shaped sliding plate 12. A rotating shaft 14 is rotatably installed inside the mounting cavity 10. Gears 20 are fixedly installed around the rotating shaft 14. The four toothed plates 13 mesh with two gears 20 respectively. The L-shaped sliding plates 12 correspond to the fixing plate 5 and the fixing rod 9. A rotating rod 16 is rotatably installed inside the mounting cavity 10. Worm gears 17 are fixedly installed on both sides of the end, and turbines 15 are fixedly installed on both sides of the two rotating shafts 14. The worm gears 17 and turbines 15 mesh with each other. Four slide rails 11 are fixedly installed on the bottom of the inner wall of the mounting cavity 10. Four L-shaped slide plates 12 are slidably connected to the four slide rails 11 respectively. The circuit breaker 1 is fixedly installed on the upper side of the fixed plate 5. There are four fixed plug rods 9. The four fixed plug rods 9 are respectively set at the four corners of the upper side of the pull-out plate 8. One end of the L-shaped slide plate 12 has a snap-fit ​​groove 23. One end of the L-shaped slide plate 12 is inserted into the upper side of the fixed plug rod 9 through the snap-fit ​​groove 23. A through groove is provided on one side of the slide rail 11, so that the toothed plate 13 can be fixedly connected to one side of the L-shaped slide plate 12 through the through groove. The self-locking characteristics of the worm gear 17 and turbine 15 can improve the stability of the L-shaped slide plate 12 when limiting the fixed plate 5.

[0029] Reference Figure 3 and Figure 4 As shown, a rotating knob 18 is rotatably mounted on one side of the pull-out plate 8. The rotating knob 18 is fixedly connected to the rotating rod 16. An insertion limiting groove 19 is provided on one side of the rotating knob 18. The antistatic sealing cover 3 is located on one side of the antistatic housing 2. A groove 21 is provided on one side of the antistatic sealing cover 3. An insertion limiting block 22 is provided in the groove 21.

[0031] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0032] When using the circuit breaker 1, remove the anti-static sealing cover 3, then pull the pull-out plate 8 to move the circuit breaker 1 out of the anti-static housing 2. Next, rotate the rotary knob 18, causing the rotary rod 16 to rotate. The rotation of the rotary rod 16 drives the two worm gears 17 to rotate synchronously, which in turn drives the two rotating shafts 14 to rotate synchronously via the two worm gears 15. The synchronous rotation of the two rotating shafts 14 drives the two gears 20 to rotate synchronously, which in turn drives the four toothed plates 13 to move synchronously. The synchronous movement of the four toothed plates 13 drives the four L-shaped sliding plates 12 to move synchronously, thus enabling the four L-shaped sliding plates to move synchronously. The plate 12 simultaneously disengages from the fixed rod 9 and releases the vertical restriction on the fixed plate 5. Then, the operator pulls the circuit breaker 1 upwards, causing the fixed plate 5 to disengage from the fixed rod 9, thus completing the disassembly of the circuit breaker 1. During installation, the fixed plate 5 is inserted around the four fixed rods 9, and then the above steps are reversed, so that the four L-shaped sliding plates 12 move synchronously and are inserted around the upper ends of the four fixed rods 9. This allows the L-shaped sliding plates 12 to vertically restrict the fixed plate 5, and the fixed rods 9 to horizontally restrict the fixed plate 5, thereby fixing the circuit breaker 1 onto the pull-out plate 8. Then, the pull-out plate 8 is pushed into the anti-static housing 2, and the anti-static sealing cover 3 is fixed to one side of the anti-static housing 2.
