[0026] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] Example 1

[0028] The present embodiment provides a circuit breaker state indicating mechanism, which includes: a mounting base 100, an indicating member 200, an operating button 300 and a driving handle, the driving handle is used to connect the moving contact assembly of the circuit breaker, the operating button 300 is driven and cooperated with the indicating member 200 and the driving handle, the indicating member 200 and the operating button 300 are both rotatably arranged on the mounting base 100, the indicating member 200 has an opening indicating position and a closing indicating position, and the operating button 300 is driven to push the indicating member 200 to switch between the opening indicating position and the closing indicating position.

[0029] Please refer to Figure 1As shown, in this embodiment, the driving handle is used to connect the moving contact assembly of the circuit breaker, and the driving handle is driven and matched with the operating button 300. The operator controls the driving handle to rotate by driving the operating button 300, thereby realizing the opening or closing of the circuit breaker. The mounting seat 100 is provided with an indicator 200, and the indicator 200 is driven and matched with the operating button 300. When the operator performs the closing or opening operation through the operating button 300, the operating button 300 drives the indicator 200 to switch between the closing indication position and the opening indication position, and the operator can know the working state of the circuit breaker by observing the position of the indicator 200. Compared with the detection circuit feedback of the circuit breaker state, the mechanical structure is used in this embodiment to indicate the circuit breaker state, and the indicator 200 is directly connected to the operating button 300. The state of the operating button 300 directly reflects whether the circuit breaker is in the opening state or the closing state, and the result is more accurate, the stability is high, and the safety during operation is improved. In addition, the structure of the indicating mechanism is simple, the cost is low, it is easy to maintain, and the service life is long.

[0030] Optionally, in some implementations of the present embodiment, one end of the operating button 300 is driven to cooperate with the indicator 200, and the operating button 300 is driven to push the indicator 200 to rotate to the closing indication position. An elastic member 400 is provided on the indicator 200, and the elastic member 400 provides elastic force so that the indicator 200 has a tendency to rotate to the opening indication position.

[0031] Please refer to Figure 1 and Figure 2 As shown, in this embodiment, one end of the operating button 300 abuts against the indicator 200, and is used to push the indicator 200 to switch from the opening indication position to the closing indication position. At the same time, an elastic member 400 is provided on the indicator 200, and the elastic member 400 provides elastic force to reset the indicator 200 to the opening indication position. When the circuit breaker is in the opening state, the indicator 200 is reset to the opening indication position under the action of the elastic member 400. When the circuit breaker is closed, the operator presses the closing end of the operating button 300, and the operating button 300 drives the indicator 200 to rotate to the closing indication position, and the elastic member 400 is compressed and elastically deformed. When the circuit breaker is opened again, the operator presses the opening end of the operating button 300, and the operating button 300 is away from the indicator 200. The compressed elastic member 400 provides elastic force to rotate the indicator 200 to the opening indication position again to achieve reset. During multiple closing and opening processes, the indicator 200 repeats the above operations to display the working status of the circuit breaker in real time.

[0032] Optionally, in some implementations of the present embodiment, the indicator 200 includes an indicating portion 201 and a driving arm 202, the indicating portion 201 is rotatably connected to the mounting base 100, one end of the driving arm 202 is fixedly connected to the indicating portion 201, and the other end of the driving arm 202 abuts against the operating button 300.

[0033] The indicator member 200 includes a rotation indicator portion 201 and a driving arm 202. One end of the driving arm 202 is fixedly connected to the indicator portion 201, and the other end of the driving arm 202 abuts against the operation button 300. When the operation button 300 rotates, the driving arm 202 and the indicator portion 201 connected to the driving arm 202 are driven to rotate. The driving arm 202 forms a lever structure, which facilitates the smooth rotation of the indicator member 200 when the operation button 300 is pressed.

[0034] Optionally, in some implementations of this embodiment, the driving arm 202 and the indicating part 201 are integrally formed. On the one hand, the integrally formed indicating member 200 is convenient for subsequent assembly, simplifies the assembly steps, and improves production efficiency. On the other hand, the driving arm 202 and the indicating part 201 are integrally formed, and the connection strength is high, which prevents the driving arm 202 from breaking and improves the service life of the indicating member 200.

[0035] Optionally, in some implementations of the present embodiment, the indicating portion 201 has a status indicating surface 500, the status indicating surface 500 includes a closing area 501 and an opening area 502, an indicating window 101 is provided on the mounting base 100, when the indicating member 200 is in the closing indicating position, the closing area 501 is exposed through the indicating window 101, and when the indicating member 200 is in the opening indicating position, the opening area 502 is exposed through the indicating window 101.

[0036] Please refer to Figure 3 As shown, in this embodiment, the indicator 200 is provided with an indication surface 500, and the indication surface 500 includes a closing area 501 for indicating the closing state and an opening area 502 for indicating the opening state. An indication window 101 corresponding to the position of the indication surface 500 is provided on the mounting seat 100, and the operator can observe the position state of the indicator 200 through the indication window 101. When the indicator 200 is in the opening indication position, the opening area 502 on the indication surface 500 is aligned with the indication window 101, the opening indication area is visible through the indication window 101, and the closing indication area is not visible through the indication window 101. On the contrary, when the indicator 200 is switched to the closing indication position, the indication surface 500 rotates, the closing area 501 is aligned with the indication window 101, the closing area 501 is visible through the indication window 101, and the opening area 502 is not visible through the indication window 101. The operator can judge the state of the circuit breaker by observing whether the indication surface 500 is in the closing area 501 or the opening area 502 through the indication window 101 .

[0037] Optionally, in some implementations of the present embodiment, the opening area 502 and the closing area 501 may be respectively provided with indicator signs of different shapes or different indicator colors on the diagram, or may be marked with text to facilitate observation by operators.

[0038] In some implementations of this embodiment, a mounting column 102 is provided on the mounting seat 100, a mounting hole 203 is opened on the indicator 200, the mounting column 102 is passed through the mounting hole 203, the elastic member 400 is sleeved on the mounting column 102, and one end of the elastic member 400 is connected to the mounting seat 100, and the other end of the elastic member 400 is connected to the indicator 200.

[0039] Please refer to Figure 1 and Figure 4 As shown, in this embodiment, a mounting post 102 is provided on the inner side wall of the protective housing, and the indicator 200 is provided with a mounting hole 203, and is penetrated on the mounting post 102 through the mounting hole 203, and the indicator 200 rotates around the mounting post 102. The installation of the mounting post 102 is convenient for installing the indicator 200 and the elastic member 400, and at the same time, it can improve the stability of the indicator 200 when rotating, so as to prevent the indicator 200 from shaking when switching the opening indication position or the closing indication position, causing damage or affecting the observation of the operator. The elastic member 400 can be a torsion spring or an elastic sheet, one end of the elastic member 400 is fixedly connected to the mounting seat 100, and the other end is connected to the indicator 200. During the rotation of the indicator 200, the elastic member 400 will be twisted to cause the elastic member 400 to undergo elastic deformation, so that the elastic member 400 accumulates energy, and provides elastic force to reset the indicator 200 to the opening indication position when the switch is opened.

[0040] Optionally, in some implementations of this embodiment, the elastic member 400 is a torsion spring, and a slot 205 is respectively provided on the mounting seat 100 and the indicator member 200 , and both ends of the torsion spring are respectively clamped in the slot 205 of the mounting seat 100 and the indicator member 200 .

[0041] The indicator 200 is provided with a mounting groove 204, which is coaxially arranged with the mounting hole 203. The elastic member 400 is arranged in the mounting groove 204, and cooperates with the mounting column 102 to limit the elastic member 400, thereby preventing the elastic member 400 from falling off and ensuring the stability of the device. The two ends of the elastic member 400 are respectively clamped in the clamping grooves 205 of the mounting seat 100 and the indicator 200, ensuring that the elastic member 400 can be elastically deformed when the indicator 200 rotates. At the same time, the elastic member 400 is detachably connected to the mounting seat 100 and the indicator 200, which is convenient for replacing and maintaining the elastic member 400, thereby improving the service life of the entire indicating mechanism.

[0042] Optionally, in some implementations of the present embodiment, a limit protrusion 103 is provided on the mounting seat 100 , and the indicator 200 is rotated to the opening indicating position or the closing indicating position to abut against the limit protrusion 103 .

[0043] Under the elastic force of the elastic member 400, the indicator 200 always has a tendency to rotate to the opening indication position. When the indicator 200 is at the opening indication position, the indicator 200 abuts against the limit block to ensure that the indicator 200 can accurately stop at the opening indication position, and avoid the indicator 200 rotating at too large an angle, resulting in misalignment between the indicating surface 500 and the indicating window 101, which affects the observation of the operator. When the indicator 200 is at the opening indication position, the elastic member 400 still provides elastic force, and cooperates with the limit block to fix the indicator 200, and prevents the limit block from shaking.

[0044] Optionally, in the present embodiment, a boss 301 is provided at one end of the operation button 300 close to the indicator 200 , and the boss 301 abuts against the movable end of the driving arm 202 .

[0045] Please refer to Figure 5 As shown, in this embodiment, the boss 301 abuts against the drive arm 202. When the operating button 300 performs a closing operation, the boss 301 pushes the abutting drive arm 202 to rotate, thereby avoiding jamming between the drive arm 202 and the operating button 300 and improving smoothness during operation.

[0046] Optionally, in this embodiment, the boss 301 may be an arc-shaped structure, and the arc-shaped boss 301 pushes the drive arm 202 to further improve the smoothness of the rotation of the operating button 300, while avoiding damage caused by large friction between the drive arm 202 and the operating button 300.

[0047] Example 2

[0048] In this embodiment, the indicator 200 includes an indicating part 201 and a driving arm 202. The indicating part 201 is rotatably connected to the mounting base 100. One end of the driving arm 202 is fixedly connected to the indicating part 201. A sliding groove is provided at the other end of the driving arm 202. A driving column is provided on the operating button 300, and the driving column is slidably provided in the sliding groove.

[0049] Please refer to Figure 2As shown, in this embodiment, the driving arm 202 is a bar structure, and the operating button 300 drives the driving arm 202 to swing up and down, so that the indicator 200 switches between the closing indication position and the opening indication position. A chute is provided at one end of the driving arm 202 close to the operating button 300, and a driving boss 301 is correspondingly provided on the operating button 300. The driving boss 301 is inserted into the chute and can slide along the chute. When the circuit breaker performs the closing operation, the operating button 300 rotates, and the driving boss 301 abuts against the side wall of one side of the chute, thereby pushing the driving arm 202 to rotate, so that the indicator 200 rotates to the closing indication position. Conversely, when the circuit breaker performs the opening operation, the operating button 300 rotates in the opposite direction, and the driving boss 301 abuts against the side wall of the other side of the chute, pushing the driving arm 202 to rotate in the opposite direction, thereby resetting to the opening indication position. The chute is a bar structure, and the driving boss 301 can slide in the chute when pushing the driving arm 202 to rotate. It can be understood that the motion trajectory of the driving boss 301 and the motion route of the driving arm 202 are both arcs, and a strip-shaped slide groove is provided to avoid the driving boss 301, so as to avoid the driving arm 202 and the driving boss 301 from getting stuck, and ensure the smoothness of the indicator 200 when switching. The slide groove and the driving boss 301 are used to make the indicator 200 drive and cooperate with the operation button 300, and there is no need to use the elastic member 400, which further simplifies the driving structure, reduces the number of parts and assembly steps, and reduces the production cost. Since the elastic member 400 is not used, the indicating mechanism has fewer parts, which avoids the situation where the elastic member 400 is damaged, and further improves the service life of the indicating mechanism.
