[0025] like Figures 1 to 3 As shown, a circuit breaker padlock device comprises a miniature circuit breaker group 1, wherein the miniature circuit breaker group 1 is composed of a guide rail 101, a terminal fixture 103 and a plurality of miniature circuit breaker bodies 102, wherein a guide rail 101 for fixing the miniature circuit breaker body 102 is arranged below the miniature circuit breaker body 102, and each miniature circuit breaker body 102 is provided with a padlock device, and the padlock device is composed of a padlock device fixing portion 2 and a padlock device pressing portion 3;

[0026] In order to reduce the weight of the entire device, the padlock device is made of stainless steel, carbon steel or non-metallic material;

[0027] Specifically, the padlock device can be used to disconnect the miniature circuit breaker body 102, so that when the lower circuit corresponding to the miniature circuit breaker body 102 is not in use or under maintenance, the safety performance of the equipment during maintenance operation can be improved; the guide rail 101 can be used to install and fix multiple miniature circuit breaker bodies 102, thereby ensuring the stability of the miniature circuit breaker body 102 when in use.

[0028] like Figures 1 to 5As shown, the padlock device fixing part 2 includes a fixing plate 201, the outer side of the miniature circuit breaker body 102 is provided with a fixing plate 201, and the fixing plate 201 is provided with a lock hole 202 and a fixing hole 203 on the same horizontal axis, and the padlock device pressing part 3 includes a pressing plate 301, and the upper surface of the miniature circuit breaker body 102 is provided with a pressing plate 301, and the pressing plate 301 is provided with a lock hole 202 and a fixing hole 203 corresponding to the lock hole 202 and the fixing hole 203 respectively;

[0029] Specifically, the metal ring for padlocking can be fixed by the provided lock hole 202 and the lock hole 2 302 to lock the disconnecting position of the miniature circuit breaker body 102. The hanging metal ring can not only serve as a warning, but also prevent the miniature circuit breaker body 102 from being mistakenly operated and closed, and can enhance the safety performance of the equipment during maintenance operation when the lower-level circuit corresponding to the miniature circuit breaker body 102 is not in use or under maintenance; in addition, the provided fixing hole 1 203 and the fixing hole 2 303 facilitate the assembly of the padlock device fixing part 2 and the padlock device pressing part 3, enhance the stability of the padlock device installed on the miniature circuit breaker body 102, and ensure the stability of the disconnecting position of the miniature circuit breaker body 102.

[0030] like Figures 1 to 3 As shown, the fixing hole 1 203 and the fixing hole 2 303 are fixedly connected by bolts;

[0031] Specifically, by threading the bolts into the fixing hole 1 203 and the fixing hole 2 303 from front to back, the fixing plate 201 and the pressing plate 1 301 can be installed and fixed, thereby improving the stability of the padlock device when in use.

[0032] like Figure 4 As shown, one end of the fixing plate 201 close to the miniature circuit breaker group 1 is connected with a clamping plate 204;

[0033] Specifically, by inserting the clamping plate 204 into the gap between the miniature circuit breaker body 102 and the guide rail 101 , the stability of the miniature circuit breaker body 102 installed on the guide rail 101 is enhanced.

[0034] like Figure 5 As shown, one side of the pressing plate 1 301 is connected to the pressing plate 2 304;

[0035] Specifically, the second pressing plate 304 can press the top (head) of the miniature circuit breaker body 102 , and cooperate with the clamping plate 204 to improve the stability of the miniature circuit breaker body 102 installed on the guide rail 101 .

[0036] When in use, the operator can fix the guide rail 101 on the mounting plate (mounting strip) of the power distribution cabinet or control cabinet, and then install multiple miniature circuit breaker bodies 102 on the guide rail 101 in sequence (the commonly used guide rail 101 has a width of 35 mm and a depth of 7.5 mm at the padlock device pressure part). After the miniature circuit breaker body 102 is installed on the guide rail 101, there is a certain amount of gap between the bottom of the miniature circuit breaker body 102 and the guide rail 101. Then tighten the fixing plate 201. The fixing plate 201 is installed close to the miniature circuit breaker body 102 (in actual use, the width of the fixing plate 201 is slightly larger than the width of the guide rail 101, so that the fixing plate 201 can be smoothly inserted into the guide rail 101 until it reaches the mounting plate). At the same time, the clamping plate 204 can be inserted into the gap between the miniature circuit breaker body 102 and the guide rail 101, and the upper surface of the clamping plate 204 is in contact with the bottom surface of the miniature circuit breaker body 102 (the depth of the fixing plate 201 is less than the thickness of the miniature circuit breaker body 102);

[0037] When the miniature circuit breaker body 102 is in the disconnected state, the operating head of the miniature circuit breaker body 102 is set downward, and the second pressure plate 304 presses the operating head (top) of the miniature circuit breaker body 102 to make it inoperable. Then, the fixing hole 1 203 and the fixing hole 2 303 are connected and fixed by bolts to enhance the relative stability of the padlock device fixing part 2 and the padlock device pressing part 3 when in use. Then, the metal ring for the padlock is passed through the lock hole 1 202 and the lock hole 2 302 to lock the miniature circuit breaker body 102 in the disconnected position. When the lower-level circuit corresponding to the miniature circuit breaker body 102 is not in use or is in a maintenance state, it can be locked in the disconnected position by the provided padlock device to ensure the safety factor of the equipment during operation.

[0038] In summary, the padlock device can be used to disconnect the miniature circuit breaker body 102. The metal ring for padlocking can be fixed by the lock hole 1 202 and the lock hole 2 302 to lock the disconnecting position of the miniature circuit breaker body 102. The hanging metal ring can not only serve as a warning, but also prevent the miniature circuit breaker body 102 from being mistakenly closed. When the lower circuit corresponding to the miniature circuit breaker body 102 is not in use or under maintenance, the safety performance of the equipment during maintenance operation can be improved. The guide rail 101 can be used to install and fix multiple miniature circuit breaker bodies 102, thereby ensuring the stability of the miniature circuit breaker body 102 when in use.
