[0015] A method for using an anti-interference miniature circuit breaker comprises the following steps:

[0016] Step 1: The staff pulls the square plate to move downward, and the square plate drives the sliding frame to move downward. Then, multiple circuit breakers are placed on the inner wall of the fixed frame, and the square plate is released. The first spring drives the sliding frame to move upward due to the elastic deformation of the first spring.

[0017] Step 2: The circuit breaker is squeezed during the upward movement of the sliding frame, and then the telescopic rod is started, the telescopic rod drives the lifting frame to move downward, and the lifting frame drives the first extrusion shell to move downward;

[0018] Step 3: The first extrusion shell drives the first rotating belt to move downward, and the first rotating belt presses the bearing plate downward during the downward movement, so that the bearing plate drives the square shell to move downward, the second spring of the square shell moves downward, and the second spring drives the lifting plate to move downward;

[0019] Step 4: The lifting plate drives the vertical rod to move downward, the vertical rod drives the lower pressure plate to move downward, the lower pressure plate drives the sealing ring to move downward, and the sealing ring presses down the top of the circuit breaker during the downward movement.

[0020] The present invention has the following beneficial effects:

[0021] (1) In the present invention, a worker pulls the square plate to move the square plate downward, and the square plate drives the sliding frame to move downward. Then, a plurality of circuit breakers are placed on the inner wall of the fixed frame. The square plate is released, and the first spring elastically deforms the sliding frame, and the first spring drives the sliding frame to move upward. During the upward movement of the sliding frame, the circuit breaker is squeezed so that the circuit breaker can be quickly installed on the inner wall of the fixed frame. Then, the telescopic rod is started, and the telescopic rod drives the lifting frame to move downward. The lifting frame drives the first extrusion shell to move downward. The first extrusion shell drives the first rotating belt to move downward. During the downward movement of the first rotating belt, the bearing The carrier plate performs a downward pressing movement, so that the carrier plate drives the square shell to move downward, the second spring of the square shell moves downward, the second spring drives the lifting plate to move downward, the lifting plate drives the vertical rod to move downward, the vertical rod drives the lower pressure plate to move downward, the lower pressure plate drives the sealing ring to move downward, and the top of the circuit breaker is pressed downward during the downward movement of the sealing ring. Because the elastic potential energy of the second spring is greater than that of the first spring, the first spring is elastically deformed, and the sealing ring presses down the circuit breaker and the sliding frame supports the circuit breaker, thereby improving the installation stability of the circuit breaker and improving the working effect of the circuit breaker.

[0022] (2) According to the present invention, when the lifting frame moves downward, the slot setting of the irregular hole causes the lifting frame to move away from each other, the locking rod drives the moving frame to move away from each other, the moving frame drives the lifting rod to move away from each other, the lifting rod drives the bearing plate to move away from each other, the bearing plate drives the square shell to move away from each other, the square shell drives the lifting plate to move away from each other, the lifting plate drives the vertical rod to move away from each other, the vertical rod drives the lower pressure plate to move away from each other, the lower pressure plate drives the sealing ring to move away from each other, at this time, the bottom of the sealing ring contacts the top of the circuit breaker, so that the sealing ring can drive the multiple circuit breakers to move away from each other, at this time, the multiple circuit breakers are evenly distributed, and the lifting plate is provided. The heat dissipation effect of the circuit breaker is improved when the circuit breaker is working, and the working efficiency of the circuit breaker is improved laterally. When the first spring can no longer perform elastic deformation, the reaction force of the circuit breaker makes the sealing ring fit tightly with the circuit breaker and can make the sealing ring move upward, the sealing ring drives the lower pressure plate to move upward, the lower pressure plate drives the vertical rod to move upward, and the vertical rod drives the lifting plate to move toward the top of the inner wall of the square shell. At this time, negative pressure is generated at the bottom of the inner wall of the square shell, and the negative pressure enters the interior of the vertical pipe through the setting of the circular hole, and the negative pressure enters the connection between the sealing ring and the circuit breaker through the vertical pipe, thereby improving the connection effect between the sealing ring and the circuit breaker, preventing the sealing ring from detaching from the circuit breaker, and improving the movement stability of the circuit breaker laterally.

[0023] (3) According to the present invention, when the lifting plate moves upward, the lifting plate drives the rotating bar to move upward. The rotating bar drives the slider to slide along the outer wall of the limiting rod, the slider drives the connecting frame to move, the connecting frame drives the clamping shell to move, the clamping shell drives the connecting plate to move, and the connecting plate drives the rubber cone block to move. The rubber cone block can squeeze the outer wall of the circuit breaker during the movement, further preventing the circuit breaker from falling off during the movement, thereby improving the movement stability of the circuit breaker. Under the reaction force of the circuit breaker, the rubber cone block drives the connecting plate to slide toward the inside of the clamping shell. When the connecting plate moves to one end of the inside of the clamping shell, the connecting plate no longer blocks the bent pipe. At this time, when the lifting plate slides toward the top of the square shell, the airflow above the square shell enters the inside of the bent pipe, the airflow enters the clamping shell through the bent pipe, and the airflow sprays toward the outer wall of the circuit breaker through the clamping shell, thereby further dissipating heat for the circuit breaker.

[0024] (4) According to the present invention, when the sliding frame moves downward, the sliding frame drives the concave frame to move downward, and the concave frame drives the rotating plate to move downward. Limited by the slide groove, the rotating plate drives the square rod to slide along the outer wall of the slide groove, and the square rod drives the second extruded shell to approach the connecting frame. The second extruded shell drives the second rotating belt to move, so that the second rotating belt contacts the outer wall of the connecting frame, further improving the clamping effect of the rubber cone block on the circuit breaker and improving the stability of the circuit breaker movement process. The second rotating belt can rotate on the inner wall of the second extruded shell. When the connecting frame moves, the connecting frame contacts the outer wall of the second rotating belt, so that the rolling friction is converted into sliding friction, thereby preventing the connecting frame from getting stuck during movement and improving the operation stability of the connecting frame.

The circular holes 677 are arranged inside the square shell 665. When the lifting frame 4 moves downward, it is affected by the slot setting of the irregular hole 5. The lifting frame 4 causes the plurality of clamping rods 666 located inside the irregular hole 5 to move away from each other, and the clamping rods 666 drive the movement The frames 661 move away from each other, the movable frame 661 drives the lifting rod 663 to move away from each other, the lifting rod 663 drives the bearing plate 664 to move away from each other, the bearing plate 664 drives the square shell 665 to move away from each other, the square shell 665 drives the lifting plate 672 to move away from each other, the lifting plate 672 drives the vertical rod 673 to move away from each other, the vertical rod 673 drives the lower pressure plate 674 to move away from each other, and the lower pressure plate 674 drives the sealing ring 675 to move away from each other.

[0050] Step 1: The staff pulls the square plate 63 to move the square plate 63 downward, and the square plate 63 drives the sliding frame 62 to move downward. Then, a plurality of circuit breakers 65 are placed on the inner wall of the fixed frame 2, and the square plate 63 is released. The first spring 64 elastically deforms, and the first spring 64 drives the sliding frame 62 to move upward.

[0054] When in use, the staff pulls the square plate 63 to move the square plate 63 downward, and the square plate 63 drives the sliding frame 62 to move downward, and then places multiple circuit breakers 65 on the inner wall of the fixed frame 2, loosens the square plate 63, and is elastically deformed by the first spring 64. The first spring 64 drives the sliding frame 62 to move upward, and the circuit breaker 65 is squeezed during the upward movement of the sliding frame 62, so that the circuit breaker 65 can be quickly installed on the inner wall of the fixed frame 2, and then starts the telescopic rod 3, the telescopic rod 3 drives the lifting frame 4 to move downward, and the lifting frame 4 drives the first extrusion shell 667 to move downward, and the first extrusion shell 667 drives the first rotating belt 668 to move downward, and the first rotating belt 668 presses the bearing plate 664 downward during the downward movement, so that The bearing plate 664 drives the square shell 665 to move downward, the second spring 671 of the square shell 665 moves downward, the second spring 671 drives the lifting plate 672 to move downward, the lifting plate 672 drives the vertical rod 673 to move downward, the vertical rod 673 drives the lower pressure plate 674 to move downward, the lower pressure plate 674 drives the sealing ring 675 to move downward, and the sealing ring 675 presses down on the top of the circuit breaker 65 during the downward movement. Because the elastic potential energy of the second spring 671 is greater than that of the first spring 64, the first spring 64 is elastically deformed, and the sealing ring 675 presses down on the circuit breaker 65 and the sliding frame 62 supports the circuit breaker 65, thereby improving the installation stability of the circuit breaker 65 and improving the working effect of the circuit breaker 65.

[0055] When the lifting frame 4 moves downward, due to the slot setting of the irregular hole 5, the lifting frame 4 makes the multiple clamping rods 666 located inside the irregular hole 5 move away from each other, the clamping rods 666 drive the moving frame 661 to move away from each other, the moving frame 661 drives the lifting rods 663 to move away from each other, the lifting rods 663 drive the bearing plates 664 to move away from each other, the bearing plates 664 drive the square shells 665 to move away from each other, the square shells 665 drive the lifting plates 672 to move away from each other, the lifting plates 672 drive the vertical rods 673 to move away from each other, the vertical rods 673 drive the lower pressure plates 674 to move away from each other, the lower pressure plates 674 drive the sealing rings 675 to move away from each other, at this time, the bottom of the sealing ring 675 contacts the top of the circuit breaker 65, so that the sealing ring 675 can drive the multiple circuit breakers 65 to move away from each other, at this time, the multiple circuit breakers 65 are evenly distributed, which improves the circuit breaker The heat dissipation effect of the circuit breaker 65 when it is working improves the working efficiency of the circuit breaker 65 laterally. When the first spring 64 can no longer perform elastic deformation, the reaction force of the circuit breaker 65 makes the sealing ring 675 fit closely with the circuit breaker 65 and enables the sealing ring 675 to move upward. The sealing ring 675 drives the lower pressure plate 674 to move upward, and the lower pressure plate 674 drives the vertical rod 673 to move upward. The vertical rod 673 drives the lifting plate 672 to move toward the top of the inner wall of the square shell 665. At this time, negative pressure is generated at the bottom of the inner wall of the square shell 665. The negative pressure enters the interior of the vertical pipe 676 through the setting of the circular hole 677, and the negative pressure enters the connection between the sealing ring 675 and the circuit breaker 65 through the vertical pipe 676, thereby improving the connection effect between the sealing ring 675 and the circuit breaker 65, preventing the sealing ring 675 from detaching from the circuit breaker 65, and laterally improving the movement stability of the circuit breaker 65.

[0056] When the lifting plate 672 moves upward, the lifting plate 672 drives the rotating bar 682 to move upward, which is limited by the limiting rod 681. The rotating bar 682 drives the slider 683 to slide along the outer wall of the limiting rod 681, and the slider 683 drives the connecting frame 684 to move. The connecting frame 684 drives the clamping shell 685 to move, and the clamping shell 685 drives the connecting plate 687 to move. The connecting plate 687 drives the rubber cone block 688 to move. The rubber cone block 688 can squeeze the outer wall of the circuit breaker 65 during the movement, so as to further prevent the circuit breaker 65 from falling off during the movement, thereby improving the safety of the circuit breaker 65. In order to ensure the movement stability of the circuit breaker 65 and to be subjected to the reaction force of the circuit breaker 65, the rubber cone block 688 drives the connecting plate 687 to slide into the inside of the clamping shell 685. When the connecting plate 687 moves to one end inside the clamping shell 685, the connecting plate 687 no longer blocks the elbow 689. At this time, when the lifting plate 672 slides above the square shell 665, the airflow above the square shell 665 enters into the inside of the elbow 689, and the airflow enters the clamping shell 685 through the elbow 689. The airflow passes through the clamping shell 685 to spray toward the outer wall of the circuit breaker 65, thereby further dissipating heat for the circuit breaker 65.

[0057] When the sliding frame 62 moves downward, the sliding frame 62 drives the concave frame 691 to move downward, and the concave frame 691 drives the rotating plate 692 to move downward. Limited by the sliding groove 693, the rotating plate 692 drives the square rod 694 to slide along the outer wall of the sliding groove 693, and the square rod 694 drives the second extruded shell 695 to approach the connecting frame 684. The second extruded shell 695 drives the second rotating belt 696 to move, so that the second rotating belt 696 contacts the outer wall of the connecting frame 684, further improving the clamping effect of the rubber cone block 688 on the circuit breaker 65, and improving the stability of the moving process of the circuit breaker 65. The second rotating belt 696 can rotate on the inner wall of the second extruded shell 695. When the connecting frame 684 moves, the connecting frame 684 contacts the outer wall of the second rotating belt 696, so that the rolling friction is converted into sliding friction, thereby preventing the connecting frame 684 from getting stuck during movement and improving the operation stability of the connecting frame 684.
