[0002] In today's world where electricity is widely used, to ensure safe operation of circuits, disconnecting switch mechanisms with limit baffles are typically incorporated into the circuit to perform closing, opening, and grounding actions. When closed, the circuit is conductive; when opened, the circuit is disconnected; and when grounded, the circuit is grounded.

[0003] However, in the existing technology, there are still problems such as the inconvenience in determining the position of the disconnecting switch mechanism with limit baffles, and the inconvenience in determining whether the operation of the disconnecting switch mechanism with limit baffles is in place. Utility Model Content

[0008] The mounting body is located inside the housing;

[0009] An output shaft is rotatably connected to the mounting body and is used to rotate relative to the mounting body to perform closing, opening, and grounding.

[0010] An indicating device includes an indicating disk, which is rotatably connected to the mounting body via a rotating shaft; and the rotating shaft is drively connected to the output shaft; the upper surface of the indicating disk is provided with a first region, a second region, and a third region spaced apart.

[0011] When the output shaft closes, the first area is exposed through the observation hole; when the output shaft opens, the second area is exposed through the observation hole; when the output shaft grounds, the third area is exposed through the observation hole.

[0012] The advantages of the disconnecting switch mechanism with limiting baffle provided by this utility model compared with the prior art include:

Based on this, the operator can determine the state of the disconnector mechanism with limit baffles based on the area of ​​the indicator panel exposed through the observation hole, and can also determine whether the operation of the disconnector mechanism with limit baffles has been completed based on the portion of the indicator panel exposed through the observation hole. Therefore, the disconnector mechanism with limit baffles provided by this invention can improve the problems of inconvenience in judging the state and whether the operation has been completed in existing disconnector mechanisms with limit baffles.

[0014] Optionally, the first region is provided with a first indicator; the second region is provided with a second indicator; and the third region is provided with a third indicator; the first indicator, the second indicator, and the third indicator are different from each other.

When the first region is exposed from the observation hole, the indicator disk covers the grounding operation shaft. When the third region is exposed from the observation hole, the indicator disk covers the closing operation shaft. When the second region is exposed from the observation hole, the indicator disk avoids the grounding operation shaft and the closing operation shaft.

[0030] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0031] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0032] Please refer to the following: Figures 1-3 This application provides a disconnecting switch mechanism 10 with a limit baffle and a disconnecting switch operated using the disconnecting switch mechanism 10 with the limit baffle. The disconnecting switch mechanism 10 with the limit baffle and the disconnecting switch can be applied to a disconnecting switch, which can be applied to a circuit. The disconnecting switch mechanism 10 with the limit baffle is used to operate the disconnecting switch to perform functions such as closing, opening, and grounding. When the disconnecting switch mechanism 10 with the limit baffle and the disconnecting switch perform closing, the circuit is connected; when opening, the circuit is disconnected; and when grounding, the circuit is grounded. It is worth noting that the disconnecting switch mechanism 10 with the limit baffle and the disconnecting switch provided in this embodiment can improve the problem that in the prior art, the disconnecting switch mechanism 10 with the limit baffle is inconvenient to determine its current state and whether the operation is in place.

[0033] In this embodiment, the disconnecting switch mechanism 10 with a limiting baffle includes a housing, a mounting body, an output shaft, and an indicating device 300. The housing has an observation hole. The mounting body is located inside the housing. The output shaft is rotatably connected to the mounting body and is used to rotate relative to the mounting body to perform closing, opening, and grounding operations. The indicating device 300 includes an indicating disk 301, which is rotatably connected to the mounting body via a rotating shaft 302; and the rotating shaft 302 is drively connected to the output shaft. The upper surface of the indicating disk 301 has a first region 310, a second region 320, and a third region 330 spaced apart. When the output shaft performs closing, the first region 310 is exposed through the observation hole; when the output shaft performs opening, the second region 320 is exposed through the observation hole; and when the output shaft performs grounding, the third region 330 is exposed through the observation hole.

[0034] The intervals between the first region 310, the second region 320, and the third region 330 indicate that there is no overlap between any two of them. This means that when the first region 310 is visible through the observation hole, the second region 320 and the third region 330 cannot be visible through the observation hole; similarly, when the second region 320 is visible through the observation hole, the first region 310 and the third region 330 cannot be visible through the observation hole; similarly, when the third region 330 is visible through the observation hole, the first region 310 and the second region 320 cannot be visible through the observation hole.

[0035] As described above, in the disconnector mechanism 10 with limit baffles, when closing, opening, and grounding are performed via the output shaft, if closing is complete, the first area 310 of the indicator panel 301 will be exposed through the observation hole; if opening is complete, the second area 320 of the indicator panel 301 will be exposed through the observation hole; and if grounding is complete, the third area 330 of the indicator panel 301 will be exposed through the observation hole. Based on this, the operator can determine the state of the disconnector mechanism 10 with limit baffles based on the area of ​​the indicator panel 301 exposed through the observation hole, and can also determine whether the operation of the disconnector mechanism 10 with limit baffles is complete based on the portion of the indicator panel 301 exposed through the observation hole. Therefore, the disconnector mechanism 10 with limit baffles provided by this utility model can improve the problems of inconvenience in judging the state and whether the operation is complete in the existing disconnector mechanism 10 with limit baffles.

[0036] Optionally, to facilitate operator judgment, in this embodiment, a first indicator 311 is provided on the first region 310; a second indicator 321 is provided on the second region 320; and a third indicator 331 is provided on the third region 330; the first indicator 311, the second indicator 321, and the third indicator 331 are different from each other.

[0037] The first indicator 311, the second indicator 321, and the third indicator 331 can be distinguished not only by different shapes of graphics, but also by different colors and materials. This allows the operator to accurately determine the state of the isolating switch mechanism 10 with limit baffles.

[0038] In this embodiment, to further improve safety, the disconnecting switch mechanism 10 with a limit baffle also includes a closing operation shaft 210 and a grounding operation shaft 220. Both the closing operation shaft 210 and the grounding operation shaft 220 are drively connected to the output shaft. The closing operation shaft 210 is used to drive the output shaft to perform closing and opening operations, and the grounding operation shaft 220 is used to drive the output shaft to perform grounding operations. When the first region 310 is exposed from the observation hole, the indicator disk 301 covers the grounding operation shaft 220; when the third region 330 is exposed from the observation hole, the indicator disk 301 covers the closing operation shaft 210; when the second region 320 is exposed from the observation hole, the indicator disk 301 avoids the grounding operation shaft 220 and the closing operation shaft 210.

[0039] In other words, when the circuit is closed, the indicator panel 301 blocks the grounding operating shaft 220, preventing the operator from directly operating the grounding mechanism. If the operator needs to operate the grounding operating shaft 220, the output shaft must be rotated to the open position to allow the grounding operating shaft 220 to be cleared. Conversely, when the third zone 330 is exposed through the observation hole, the indicator panel 301 blocks the closing operating shaft 210, preventing the operator from directly operating it. The grounding must first be released so that the indicator panel 301 can move away from the closing operating shaft 210. This prevents damage to the equipment caused by operating the grounding mechanism while the circuit is closed and also avoids the risk of electric shock to the operator.

[0040] Furthermore, in this embodiment, the disconnecting switch mechanism 10 with the limiting baffle also includes a grounding transition shaft, which is sleeved on the grounding operating shaft 220 and can rotate freely relative to the grounding operating shaft 220; the grounding transition shaft is drivenly connected to the output shaft; the rotating shaft 302 is drivenly connected to the grounding transition shaft. That is, when the closing operating shaft 210 drives the output shaft to rotate, the output shaft transmits power to the grounding transition shaft, and the grounding transition shaft then transmits power to the rotating shaft 302, thereby driving the indicator panel 301.

[0041] The rotating shaft 302 is connected to the grounding transition shaft via gear transmission.

[0042] In this embodiment, the upper surface of the indicator dial 301 is attached to the inner wall of the housing. This allows the first region 310, the second region 320, and the third region 330 on the indicator dial 301 to be easily exposed through the observation hole, facilitating operator observation and improving the user experience.

[0043] In summary, in the disconnector mechanism 10 with limit baffles and the disconnector switch, when closing, opening, and grounding are performed via the output shaft, if closing is complete, the first area 310 of the indicator panel 301 will be exposed through the observation hole; if opening is complete, the second area 320 of the indicator panel 301 will be exposed through the observation hole; and if grounding is complete, the third area 330 of the indicator panel 301 will be exposed through the observation hole. Based on this, the operator can determine the state of the disconnector mechanism 10 with limit baffles based on the area of ​​the indicator panel 301 exposed through the observation hole, and can also determine whether the operation of the disconnector mechanism 10 with limit baffles is complete based on the portion of the indicator panel 301 exposed through the observation hole. Therefore, the disconnector mechanism 10 with limit baffles provided by this utility model can improve the problems of inconvenience in judging the state and whether the operation is complete in the existing disconnector mechanism 10 with limit baffles. Furthermore, when the circuit is closed, the indicator panel 301 blocks the grounding operation shaft 220, preventing the operator from directly operating the grounding mechanism. If the operator needs to operate the grounding operation shaft 220, the output shaft must be rotated to the open position to allow the grounding operation shaft 220 to be cleared. Conversely, when the third zone 330 is exposed through the observation hole, the indicator panel 301 blocks the closing operation shaft 210, preventing the operator from directly operating it. The grounding must first be released so that the indicator panel 301 can move away from the closing operation shaft 210. This prevents damage to the equipment caused by operating the grounding mechanism while the circuit is closed and also avoids the risk of electric shock to the operator.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
