[0027] Example 1

[0028] The present embodiment provides a circuit breaker state indicating mechanism, which includes: an indicating member 100, a protective housing 300, an operating button 600 and a driving handle 200, wherein the indicating member 100 and the driving handle 200 are rotatably connected to the protective housing 300 respectively, the operating button 600 is drivingly matched with the driving handle 200, the driving handle 200 is used to connect the moving contact mechanism of the circuit breaker, and the indicating member 100 is drivingly matched with the driving handle 200, the indicating member 100 has a closing indicating position and an opening indicating position, and the driving handle 200 is driven to drive the indicating member 100 to switch between the closing indicating position and the opening indicating position.

[0029] Please refer to Figure 1 and Figure 5As shown, in this embodiment, the driving handle 200 cooperates with the moving contact assembly of the circuit breaker, and the driving handle 200 is rotated during the opening or closing process of the circuit breaker. At this time, the driving handle 200 drives the indicator 100 to switch between the closing position and the opening position. The operator can determine whether the circuit breaker is in the opening or closing state by observing whether the indicator 100 is in the opening position or the closing position. Compared with the detection circuit to feedback the circuit breaker state, the mechanical structure is used in this embodiment to indicate the circuit breaker state, which has high stability, is not easy to damage, and has a simple structure, low cost, and is easy to maintain. The operating button 600 is driven and cooperated with the driving handle 200, and the driving handle 200 is used to connect the moving contact mechanism of the circuit breaker. The operator can drive the operating button 600 to rotate the driving handle 200 to open or close the circuit breaker.

[0030] Optionally, in some implementations of the present embodiment, a protective shell 300 is provided on the outer cover of the indicator 100 and the driving handle 200, and the indicator 100 and the driving handle 200 are rotatably connected to the protective shell 300 respectively.

[0031] Please refer to Figure 1 As shown, in this embodiment, the outer cover of the indicator 100 and the driving handle 200 is provided with a protective shell 300. On the one hand, the protective shell 300 plays the role of a mounting seat, and the indicator 100 and the driving handle 200 are rotatably arranged inside the protective shell 300. On the other hand, the driving handle 200 and the indicator 100 are encapsulated by the protective shell 300 to ensure the stability of the indicator 100, and to prevent the indicator 100 from being damaged by external impact or affecting the indicating effect of the indicator 100.

[0032] Optionally, in some implementations of the present embodiment, an indication surface 400 is provided on the indicator 100, and the indication surface 400 has a closing area 401 and an opening area 402. An indication window 301 is opened on the protective shell 300. When the indicator 100 is in the closing indication position, the closing area 401 is aligned with the indication window 301, and when the indicator 100 is in the opening indication position, the opening area 402 is aligned with the indication window 301.

[0033] Please refer to Figure 3As shown, in this embodiment, the indicator 100 is provided with an indication surface 400, and the indication surface 400 includes a closing area 401 for indicating the closing state and an opening area 402 for indicating the opening state. An indication window 301 corresponding to the position of the indication surface 400 is provided on the protective housing 300, and the operator can observe the position state of the indicator 100 through the indication window 301. When the indicator 100 is in the opening indication position, the opening area 402 on the indication surface 400 is aligned with the indication window 301, the opening indication area is visible through the indication window 301, and the closing indication area is not visible through the indication window 301. On the contrary, when the indicator 100 is switched to the closing indication position, the indication surface 400 rotates, the closing area 401 is aligned with the indication window 301, the closing area 401 is visible through the indication window 301, and the opening area 402 is not visible through the indication window 301. The operator can judge the state of the circuit breaker by observing whether the indication surface 400 is in the closing area 401 or the opening area 402 through the indication window 301 .

[0034] Optionally, in some implementations of this embodiment, the closing area 401 and the opening area 402 are respectively provided with indication marks.

[0035] The opening area 402 and the closing area 401 may be provided with indication signs of different shapes or different indication colors on the diagram, or may be marked with text to facilitate observation by operators.

[0036] Optionally, in some implementations of the present embodiment, the indicator 100 includes a rotation indicating part 101 and a driving swing arm 102, one end of the driving swing arm 102 is fixedly connected to the rotation indicating part 101, and the other end of the driving swing arm 102 is drivingly connected to the driving handle 200, and the driving handle 200 drives the driving swing arm 102 to rotate, thereby driving the rotation indicating part 101 to rotate, so that the indicator 100 switches between the closing indication position and the opening indication position.

[0037] Please refer to Figure 2 and Figure 3 As shown, in this embodiment, the indicator 100 includes a rotation indicating portion 101 and a driving swing arm 102. An indicating surface 400 is provided on the rotation indicating portion 101, one end of the driving swing arm 102 is fixedly connected to the rotation indicating portion 101, and the other end of the driving swing arm 102 is driven and matched with the operating handle. When the operating handle rotates, the driving swing arm 102 and the rotation indicating portion 101 connected to the driving swing arm 102 are driven to rotate, and the position of the indicating surface 400 on the rotation indicating portion 101 changes, so that the opening area 402 or the closing area 401 is aligned with the indicating window 301, thereby indicating the current state of the circuit breaker.

[0038] Optionally, in some implementations of this embodiment, the driving swing arm 102 and the rotation indicating part 101 are integrally formed. On the one hand, the integrally formed indicating member 100 is convenient for subsequent assembly, simplifies the assembly steps, and improves production efficiency. On the other hand, the driving swing arm 102 and the rotation indicating part 101 are integrally formed, and the connection strength is high, which prevents the driving swing arm 102 from breaking and improves the service life of the indicating member 100.

[0039] Optionally, in some implementations of the present embodiment, a driving boss 201 is provided on the driving handle 200 , a sliding groove 103 is provided at one end of the driving swing arm 102 close to the driving handle 200 , and the driving boss 201 is slidably disposed in the sliding groove 103 .

[0040] Please refer to Figure 2 As shown, in this embodiment, the driving swing arm 102 is a bar structure, and the driving handle 200 drives the driving swing arm 102 to swing up and down, so that the indicator 100 switches between the closing indication position and the opening indication position. A sliding groove 103 is provided at one end of the driving swing arm 102 close to the driving handle 200, and a driving boss 201 is correspondingly provided on the driving handle 200. The driving boss 201 is inserted into the sliding groove 103 and can slide along the sliding groove 103. When the circuit breaker performs the closing operation, the driving handle 200 rotates, and the driving boss 201 abuts against the side wall of one side of the sliding groove 103, thereby pushing the driving swing arm 102 to rotate, so that the indicator 100 rotates to the closing indication position. Conversely, when the circuit breaker performs the opening operation, the driving handle 200 rotates in the opposite direction, and the driving boss 201 abuts against the side wall of the other side of the sliding groove 103, pushing the driving swing arm 102 to rotate in the opposite direction, thereby resetting to the opening indication position. The slide groove 103 is a strip-shaped structure, and the driving protrusion can slide in the slide groove 103 when pushing the driving swing arm 102 to rotate. It can be understood that the movement trajectory of the driving protrusion 201 and the movement route of the driving swing arm 102 are both arcs, and the strip-shaped slide groove 103 is set to avoid the driving protrusion 201, so as to avoid the driving swing arm 102 and the driving protrusion 201 from getting stuck, thereby ensuring the smoothness of the indicator 100 when switching.

[0041] Optionally, in this embodiment, one or more limit blocks 302 may be provided inside the protective housing 300. The indicator 100 switches between the closing indication position and the opening indication position through a rotation operation, and when the indicator 100 rotates to the opening indication position or the closing indication position, it abuts against the limit block 302, thereby ensuring that the indicator 100 can accurately stop at the opening indication position or the closing indication position, and avoiding the indicator 100 from rotating too much, resulting in misalignment between the indication surface 400 and the indication window 301, which affects the observation of the operator.

[0042] Example 2

[0043] Please refer to Figure 4As shown, in this embodiment, a pushing block 202 is provided on the driving handle 200, and the pushing block 202 abuts against the end of the driving swing arm 102 away from the indicating part. The pushing block 202 is driven to push the driving swing arm 102 to rotate, so that the indicating member 100 rotates to the closing indicating position. The indicating part is provided with an elastic member 500, and the elastic member 500 provides elastic force to reset the indicating member 100 to the opening indicating position.

[0044] Please refer to Figure 4 As shown, in this embodiment, a mounting post 303 is provided on the inner side wall of the protective housing 300, and the indicator 100 is provided with a mounting hole 104, and is penetrated on the mounting post 303 through the mounting hole 104, and the indicator 100 rotates around the mounting post 303. An elastic member 500 is provided on the mounting post 303, and the elastic member 500 provides elastic force for the indicator 100 so that the indicator 100 has a tendency to rotate to the opening indication position. A push block 202 is provided on the driving handle 200, and the push block 202 abuts against the movable end of the driving swing arm 102. When the circuit breaker is in the opening state, the indicator 100 is reset to the opening indication position under the action of the elastic member 500, and the opening area 402 of the indicating surface 400 is aligned with the indicating window 301. When the circuit breaker is closed, the driving handle 200 rotates, and the push block 202 pushes the driving swing arm 102, so that the indicator 100 rotates to the closing indication position. At this time, the closing area 401 of the indication surface 400 is aligned with the indication window 301, and the elastic member 500 is compressed and elastically deformed. When the circuit breaker is opened again, the driving handle 200 rotates in the opposite direction, and the push block 202 moves away from the driving swing arm 102. The compressed elastic member 500 provides elastic force, so that the indicator 100 rotates to the opening indication position again, and reset is achieved.

[0045] Optionally, in some implementations of the present embodiment, a limit block 302 may be provided inside the protective housing 300. During installation, a portion of pressure may be applied to the elastic member 500 in advance, so that the indicator 100 always has a tendency to rotate to the opening indication position. When the indicator 100 is located at the opening indication position, the indicator 100 abuts against the limit block 302 to ensure that the indicator 100 can accurately stop at the opening indication position, and avoid the indicator 100 rotating at too large an angle, causing the indication surface 400 and the indication window 301 to be misaligned, affecting the operator's observation. When the indicator 100 is located at the opening indication position, the elastic member 500 still provides elastic force, and cooperates with the limit block 302 to fix the indicator 100, and avoids the limit block 302 from shaking.

[0046] Optionally, in some implementations of this embodiment, the circuit breaker state indication mechanism further includes an operation button 600 , and the operation button 600 is driven to cooperate with the drive handle 200 .

[0047] The operation button 600 cooperates with the driving handle 200, and the driving handle 200 can be manually operated by the operation button 600 to rotate to realize the opening or closing of the circuit breaker. Since the indicator 100 is connected and transmitted to the driving handle 200 through a mechanical structure, the opening or closing state of the circuit breaker is reflected in real time, and the indication result is more accurate and reliable, and is not affected by the external environment.

[0048] Optionally, in some other embodiments, the driving handle 200 can be connected to an external driving device, such as an external driving motor, a driving rod and other structures, to achieve automatic control without manual operation, which is more convenient for remote control and monitoring.
