DETAILED DESCRIPTION

[0024] A closing and opening device of the utility model will be described in more detail below in conjunction with the accompanying drawings, wherein preferred embodiments of the utility model are shown. It should be understood that those skilled in the art can modify the utility model described herein and still achieve the advantageous effects of the utility model. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation to the utility model.

[0025] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0026] like Figure 1-5 As shown, the embodiment of the utility model proposes a convenient and practical closing and opening device, including a device plate 1, a device seat 2, a first telescopic device 3, an opening rod 4, an opening shaft pin 5, a second telescopic device 6, a closing rod 7 and a closing shaft pin 8.

[0027] Specifically, the fixed end of the first telescopic device 3 is rotatably mounted on the device plate 1, and the telescopic end is rotatably connected to the opening rod 4; one end of the opening rod 4 is connected to the opening shaft pin 5, and the other end is rotatably mounted on the device base 2; the opening shaft pin 5 is used to engage with the opening gate of the circuit breaker; the fixed end of the second telescopic device 6 is rotatably mounted on the device plate 1, and the telescopic end is rotatably connected to the closing rod 7; one end of the closing rod 7 is connected to the closing shaft pin 8, and the other end is rotatably mounted on the device base 2; the closing shaft pin 8 is used to engage with the closing gate of the circuit breaker.

[0028] In addition, this embodiment further includes a first connector 9. Specifically, one end of the first connector 9 is connected to the telescopic end of the first telescopic device 3, and the other end of the first connector 9 is rotatably connected to the opening lever 4.

[0029] Preferably, the distance between the connection point between the opening lever 4 and the first connector 9 and the connection point between the opening lever 4 and the device seat 2 is a first length, and the distance between the connection point between the opening lever 4 and the first connector 9 and the end of the opening lever 4 close to the opening shaft pin 5 is a second length, and the first length is smaller than the second length. Since the first length is shorter, when a force is applied to one end of the opening lever 4, the shorter first length can provide a greater torque, making the operating force more effective, thereby making it easier to achieve the opening operation.

[0030] In addition, this embodiment further includes a second connector 10. Specifically, one end of the second connector 10 is connected to the telescopic end of the second telescopic device 6, and the other end of the second connector 10 is rotatably connected to the closing rod 7.

[0031] Preferably, the width from the connection point between the closing rod 7 and the second connector 10 to the connection point between the closing rod 7 and the device seat 2 is a first width, and the width from the connection point between the closing rod 7 and the second connector 10 to the end of the closing rod 7 close to the closing shaft pin 8 is a second width, and the first width is smaller than the second width. Since the first width is shorter, when a force is applied at one end of the closing rod 7, the shorter first width can provide a greater torque, making the operating force more effective, thereby making it easier to achieve the closing operation.

[0032] As a preferred embodiment, the length of the opening rod 4 is less than the length of the closing rod 7. The length of the opening rod 4 and the length of the closing rod 7 can be set according to actual conditions.

[0033] In one embodiment, a first through slot 41 is provided at one end of the opening lever 4. Specifically, one end of the opening shaft pin 5 is installed in the first through slot 41, and the other end can be engaged with the opening gate of the circuit breaker. By engaging the opening shaft pin 5 with the opening gate, it is possible to ensure a tight connection between the opening lever 4 and the opening gate, reduce shaking during operation, and improve the accuracy and reliability of operation.

[0034] In one embodiment, one end of the closing rod 7 is provided with a second through slot 71. Specifically, one end of the closing shaft pin 8 is installed in the second through slot 71, and the other end can be engaged with the closing door of the circuit breaker. By engaging the closing shaft pin 8 with the opening door, it can ensure that the connection between the closing rod 7 and the closing door is tight, reduce shaking during operation, and improve the accuracy and reliability of operation.

[0035] In this embodiment, a slot is provided on the device plate 1. Specifically, a fixed shaft is provided on the inner wall opposite to the slot; the fixed shaft passes through the fixed ends of the first telescopic device 3 and the second telescopic device 6. By passing the fixed shaft through the fixed ends of the first telescopic device 3 and the second telescopic device 6, the structural stability of the entire device can be enhanced, and displacement caused by vibration or external force during operation can be prevented while the first telescopic device 3 and the second telescopic device 6 are rotated.

[0036] Preferably, the first telescopic device 3 and the second telescopic device 6 can both be cylinders. Those skilled in the art will appreciate that, while achieving the same effect, the first telescopic device 3 and the second telescopic device 6 can also be other telescopic devices other than cylinders.

[0037] In this embodiment, a groove is provided on the device seat 2. Specifically, a connecting shaft is provided on the inner wall opposite to the groove; the connecting shaft passes through the opening lever 4 and the closing lever 7. The connecting shaft helps to maintain the accurate position of the opening lever 4 and the closing lever 7, ensuring the accuracy of the operation.

[0038] In this embodiment, when a trip operation is required, the telescopic end of the first telescopic device 3 is extended, and the end of the trip rod 4 close to the trip shaft pin 5 is rotated downward with the end close to the device seat 2 as the center until the trip shaft pin 5 is engaged with the trip gate of the circuit breaker to realize the trip operation.

[0039] When the closing operation is required, the telescopic end of the first telescopic device 3 is retracted, and the end of the opening rod 4 close to the opening shaft pin 5 rotates upward with the end close to the device seat 2 as the center until the opening shaft pin 5 is separated from the opening gate of the circuit breaker. Then, the telescopic end of the second telescopic device 6 is extended, and the end of the closing rod 7 close to the closing shaft pin 8 rotates downward with the end close to the device seat 2 as the center until the closing shaft pin 8 is engaged with the closing gate of the circuit breaker, thereby realizing the closing operation; the opening function or closing function of the circuit breaker can be realized by the above.

[0040] Furthermore, both the first telescopic device 3 and the second telescopic device 3 can be connected to a control system, such as a computer host of the equipment, to control the opening rod 4 and the closing rod 7 to be correspondingly engaged on the circuit breaker.
