This structure includes a lower mounting plate hinged to the lower ends of both sides of the mounting base. A connecting spring is fixed to the inner wall of the mounting base corresponding to the upper end of the lower mounting plate, and a ball bearing is fixed to the lower end of the connecting spring. Upper mounting plates are installed on both sides of the circuit breaker. An auxiliary rod passes through the middle of the upper mounting plate, and a rotating column is fixed to one end of each auxiliary rod.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-9 As shown, a circuit breaker structure includes a device body 1; the top left and right sides of the device body 1 are also provided with third fixing rods 26, and the front and rear ends of the device body 1 are welded together with the front and rear ends of the third fixing rods 26. A push-button switch protection mechanism is provided on the outside and inside of the device body 1.

[0035] The push-button switch protection mechanism includes a push-button switch body 27. One end of the push-button switch body 27 is sleeved on the outside of the third fixed rod 26, and the push-button switch body 27 is rotatably connected to the third fixed rod 26. A baffle 29 is inserted inside the device body 1 near the lower position of the push-button switch body 27. A first moving block 28 is sleeved on the outside of the baffle 29, and the baffle 29 and the first moving block 28 are slidably connected. The inner walls of the front and rear ends of the device body 1 near the lower position of the baffle 29 are welded to the outer sides of the front and rear ends of the fourth fixed rod 31. An elastic metal block 30 is sleeved on the outside of the fourth fixed rod 31. The top of the elastic metal block 30 contacts the bottom of the baffle 29, and the top of the elastic metal block 30 near the front and rear ends contacts the bottom of the first moving block 28.

[0036] During operation, the push-button switch bodies 27 on both sides of the top of the main body 1 are pried outwards to open, causing the push-button switch bodies 27 to rotate along the outer side of the third fixing rod 26. When the push-button switch bodies 27 rotate, they will press the first moving block 28 downwards. During the downward movement of the first moving block 28, the elastic metal block 30 will be compressed and deformed along the outer side of the fourth fixing rod 31, so that there will be a gap between the top of the elastic metal block 30 and the baffle 29, which can be used to install the wiring. Conversely, when the push-button switch bodies 27 are closed downwards, the elastic metal block 30 will return to its original position. The top of the metal block will drive the first moving block 28 to return to its original position until the top of the elastic metal block 30 touches the bottom of the baffle 29. The wiring is connected to the elastic metal block 30, and the other end of the metal block is connected to the internal circuit. The wiring is then connected from the other end of the elastic metal block, forming a complete circuit.

[0037] Furthermore, the elastic metal block 30 has two or more branch ends at its top. These multiple branch ends secure the circuit, firmly holding it in place and improving its stability.

[0038] Furthermore, the main body 27 of the push-button switch has a hole corresponding to the first moving block 28, and the main body 1 of the device has an isolation plate 34. This achieves the function of the push-button switch having a hole, solving the problem of not being able to disconnect the circuit when an accident occurs or the push-button switch is damaged and cannot be opened. The circuit can be disconnected simply by poking the moving block with a thin, long object. The isolation plate 34, acting as a creepage distance, blocks two circuit breakers installed side-by-side, preventing exposed wires from contacting adjacent wires and improving safety.

[0039] The main body 1 of the device of the present invention has a slot for installing a detachable nameplate on the top, which realizes the mass production of the main body. Different customers only need to replace the nameplate, without worrying that changes in nameplate information will prevent the product from being sold or sold, or cause inventory buildup. At the same time, it can meet the personalized customization needs of customers.

[0040] Furthermore, the rear middle position of the main body 1 is welded to the front end of the first sleeve block 10, the front end of the inner part of the first sleeve block 10 is welded to the front end of the return spring 12, the rear end of the return spring 12 is welded to the front end of the rack block 11, the rack block 11 is inserted into the first sleeve block 10, and the rack block 11 is slidably connected to the first sleeve block 10. Both the rack block 11 and the inner wall of the first sleeve block 10 are square.

[0041] During operation, the pressing plate 13 is pressed towards the rear end of the main body 1 of the device, which drives the rack block 11 to retract and move along the inside of the first set of blocks 10. When the rack block 11 moves, it will squeeze the return spring 12 inside the first set of blocks 10 to retract.

[0042] Furthermore, the rear end of the rack block 11 is welded to the front end of the pressing plate 13 near the upper position, the pressing plate 13 is sleeved on the outside of the guide rod 14 near the lower position, and the pressing plate 13 and the guide rod 14 are slidably connected. The rear end of the guide rod 14 is welded to the front end of the first limiting block 15. The guide rod 14 is designed as a round rod.

[0043] When in operation, the pressing plate 13 moves along the outside of the guide rod 14, and the first limiting block 15 can play a limiting role.

[0044] Furthermore, guide grooves 32 are also provided on the left and right sides of the first set of blocks 10. The rack block 11 is also provided with second sliders 33 on the left and right sides near the front end. The side end of the rack block 11 is welded to one side of the second slider 33. The other side of the second slider 33 passes through the guide groove 32 to reach the outside of the first set of blocks 10. The second slider 33 is slidably connected to the guide groove 32. Both the second slider 33 and the guide groove 32 are square designs.

[0045] During operation, the rack block 11 moves, causing the second slider 33 to move along the inside of the guide groove 32.

[0046] Furthermore, the upper end of the rack block 11 meshes with the spur gear 16, and the inner wall of the spur gear 16 is welded to the middle position of the outer side of the transmission rod 17. The transmission rod 17 is designed as a round rod.

[0047] During operation, the rack block 11 moves, causing the spur gear 16 and the transmission rod 17 to rotate simultaneously.

[0048] Furthermore, the left and right sides of the outer side of the transmission rod 17 are also fitted with second sleeve blocks 18, and the transmission rod 17 and the second sleeve blocks 18 are rotatably connected. The front end of the second sleeve block 18 is welded to the rear end of the device body 1, and the inner wall of the second sleeve block 18 is circular.

[0049] During operation, the outer sides of both ends of the transmission rod 17 rotate along the inside of the second set of blocks 18.

[0050] Furthermore, a second limiting block 19 is also provided on the outer side of the transmission rod 17 near the left and right ends of the second set block 18, and the outer side of the transmission rod 17 is welded to the inner wall of the second limiting block 19. The second limiting block 19 is a circular design.

[0051] During operation, the second limiting block 19 on the outer side of the transmission rod 17 can be used to limit the position of the transmission rod 17 and prevent the transmission rod 17 from moving left or right.

[0052] Furthermore, the transmission rod 17 is also provided with first helical gears 20 on both sides, and the side of the transmission rod 17 is welded to one side of the first helical gear 20. The first helical gear 20 is meshed with the second helical gear 21. The front end of the second helical gear 21 is also provided with first fixing rods 22 on both sides, and the front end of the second helical gear 21 is welded to the rear end of the first fixing rod 22. The front end of the first fixing rod 22 is welded to the rear end of the cover 23. The first fixing rod 22 is a round rod design.

[0053] During operation, the transmission rod 17 rotates, causing the first helical gears 20 on both sides to rotate clockwise simultaneously, and the first helical gears 20 drive the second helical gears 21 to rotate counterclockwise, thereby causing the first fixed rod 22 and the cover 23 to rotate simultaneously.

[0054] Furthermore, the device body 1 is also provided with second fixing rods 24 on the left and right sides of the front and rear ends, and the device body 1 and the second fixing rods 24 are welded together at one end. The front and rear ends of the cover 23 are respectively sleeved on the outside of the second fixing rods 24 at the front and rear ends of the device body 1, and the cover 23 and the second fixing rods 24 are rotatably connected. The second fixing rods 24 are designed as round rods.

[0055] When in operation, the cover 23 rotates, and the cover 23 will rotate along the outer side of the second fixing rod 24.

[0056] Furthermore, the front and rear ends of the second fixing rod 24 near the cover 23 are also fitted with a third limiting block 25, and the outer side of the second fixing rod 24 is welded to the inner wall of the third limiting block 25. The third limiting block 25 is a circular design.

[0057] During operation, the third limiting block 25 on the outer side of the second fixing rod 24 can be used to limit the position of the cover 23, preventing the cover 23 from moving back and forth along the outer side of the second fixing rod 24 first.

[0058] Working principle: When the installation line needs to be opened, first press the pressing plate 13 towards the rear end of the main body 1, causing the rack block 11 to retract and move along the inside of the first set of blocks 10. When the rack block 11 moves, it will compress the return spring 12 inside the first set of blocks 10 and retract. When the pressing plate 13 moves, it will move along the outside of the guide rod 14, and the first limiting block 15 can play a limiting role. At the same time, when the rack block 11 moves, it will move along the outside of the flat gear 16, and the rack... When block 11 moves, it drives the spur gear 16 and transmission rod 17 to rotate simultaneously. The movement of rack block 11 also drives the second slider 33 to move along the inside of the guide groove 32. When transmission rod 17 moves, the outer sides of both ends of transmission rod 17 also rotate along the inside of the second set of blocks 18. The second limiting block 19 on the outer side of transmission rod 17 can be used to limit the position of transmission rod 17, preventing it from moving left or right. Simultaneously, the rotation of transmission rod 17 drives the first helical gears 20 on both sides to rotate simultaneously. The clock hand rotates, and the first helical gear 20 drives the second helical gear 21 to rotate counterclockwise, thereby causing the first fixed rod 22 and the cover 23 to rotate simultaneously. When the cover 23 rotates, it will rotate along the outer side of the second fixed rod 24. The third limiting block 25 on the outer side of the second fixed rod 24 can be used to limit the position of the cover 23, preventing the cover 23 from moving back and forth along the outer side of the second fixed rod 24 until the cover 23 is fully rotated and opened. Then, the push switches on both sides of the top of the main body 1 are turned on. When the body 27 is pried open outwards, the main body 27 of the push switch rotates along the outer side of the third fixing rod 26. When the main body 27 of the push switch rotates, it will press the first moving block 28 downwards. During the downward movement of the first moving block 28, it will press the elastic metal block 30 to contract and deform along the outer side of the fourth fixing rod 31. When closed, the top of the elastic metal block 30 will abut the bottom of the baffle 29. When the main body 27 of the push switch is fully opened, the installation circuit can be opened.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
