Description

Technical Field

[0001] This application relates to the field of low-voltage electrical technology, and in particular to a manual operation structure for a disconnecting switch. Background Technology

[0002] Disconnect switches play an extremely important role in electrical equipment, mainly used to isolate circuits to ensure the safety of operators and the normal operation of maintenance equipment.

[0003] Existing disconnect switches typically have a pointer attached to the outer periphery of the control rod, and an indicator ring set on the side wall of the switch body. Different areas of the indicator ring are distinguished by the pointer indicating the different areas.

[0004] This type of indication can provide a relatively intuitive indication effect, but after prolonged use, the pointer may become loose or deviate, resulting in a failure to indicate the operating status of the disconnect switch and posing a certain electrical risk during use. Utility Model Content

[0005] To improve electrical safety, this application provides a manual operation structure for a disconnecting switch.

[0006] The manual operation structure of the disconnecting switch provided in this application adopts the following technical solution:

[0007] A manual operation structure for a disconnect switch includes a switch body and a control rod passing through the switch body. One end of the control rod is connected to an indicator mechanism, which includes a circuit board, an indicator light connected to the circuit board, and a fixing ring fixedly connected to the outer periphery of the control rod. A control switch for controlling the indicator light is fixedly connected to the side wall of the switch body. A pressing protrusion for pressing the control switch is fixedly connected to the outer periphery of the fixing ring. A limiting component for restricting the movement of the pressing protrusion is provided on the side of the control switch near the rotating shaft.

[0008] By adopting the above technical solution, after rotating the control lever, the retaining ring rotates with the control lever. The pressing protrusion on the retaining ring presses the control switch, turning the indicator light on or off on the circuit board, thus directly displaying the current energization status of the isolating switch. The limit component is located on the side of the control switch near the rotating shaft, used to limit the movement range of the pressing protrusion and ensure safety during operation.

[0009] Optionally, the limiting component includes a balance bar and a rotating shaft passing through the middle of the balance bar. One end of the balance bar is rotatably connected to a locking block, and the other end is rotatably connected to a limiting pressure block.

[0010] By adopting the above technical solution, when the control lever needs to be turned to another position, pressing the locking block will cause the limiting block to lift upward under the action of the balance bar, so that the limiting block will no longer restrict the movement direction of the pressing protrusion. At this time, the control lever can be rotated to realize the opening and closing operation of the disconnecting switch.

[0011] Optionally, a reset chamber is fixedly connected to the side wall of the switch body, and a fixed column passing through the bottom wall of the reset chamber is connected to the top of the limiting block. A spring is sleeved on the fixed column, and a limiting plate is circumferentially connected to the fixed column. One end of the spring abuts against the limiting plate, and the other end abuts against the inner wall of the reset chamber.

[0012] By adopting the above technical solution, the automatic reset of the limiting block can be achieved. Under the action of the spring force, the limiting block is subjected to a downward force, which keeps the limiting block in the limiting position and ensures the limiting effect of the limiting block.

[0013] Optionally, the limiting block has a guide groove on the side opposite to the control switch.

[0014] By adopting the above technical solution, the guide groove can effectively guide the pressing protrusion, so that the pressing protrusion can directly lift the limiting pressure block and make contact with the control switch. In this process, there is no need to press the locking block, which effectively improves the convenience of use.

[0015] Optionally, the limiting block is provided with a limiting protrusion on the side near the control switch.

[0016] By adopting the above technical solution, when the control rod rotates to the point where the pressing protrusion contacts the control switch, the limiting protrusion can effectively abut against the pressing protrusion, preventing the control rod from rotating in the opposite direction and effectively ensuring the safety of the disconnecting switch when opening and closing.

[0017] Optionally, a guide plate is fixedly connected to the side wall of the switch body, and the locking block passes through the guide plate.

[0018] By adopting the above technical solution, the locking block can only move up and down in the vertical direction, thereby ensuring that when the locking block is pressed, the limiting pressure block can be effectively lifted, thus ensuring stability during use.

[0019] Optionally, a fixing plate is provided on one side of the control switch for abutting against the pressing protrusion.

[0020] By adopting the above technical solution, when the pressing protrusion contacts the control switch, the pressing protrusion will abut against the fixed plate, thereby preventing the control lever from continuing to rotate. In conjunction with the limiting protrusion, the pressing protrusion is effectively limited, thus ensuring safety during use.

[0021] Optionally, a protective shell is provided on the outside of the indicating mechanism, the control rod passes through the protective shell, and the indicator light is fixedly connected to the top wall of the protective shell.

[0022] By adopting the above technical solution, the protective shell provides effective external protection for the indicating mechanism and the limiting component, preventing external dust, water droplets, etc. from affecting the operating status of the indicating mechanism and the limiting component, effectively preventing the indicating mechanism and the limiting component from rusting, and improving service life and safety.

[0023] In summary, this application has the following beneficial effects:

[0024] 1. By setting an indicator mechanism, after rotating the control lever, pressing the protrusion can effectively trigger the control switch to light up the indicator light, thereby effectively prompting the user that the closing position has been reached.

[0025] 2. By setting limit components and fixing plates, when the control switch is triggered by pressing the protrusion, it can be effectively limited by the limit components and fixing plates, thereby preventing the control rod from rotating, ensuring the stability of the opening and closing state, and ensuring electrical safety.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a manual operation structure for a disconnecting switch. (Refer to...) Figure 1 The manual operation structure of the disconnecting switch includes a switch body 1 and a control rod 2 passing through the switch body 1. By rotating the control rod 2, the opening and closing operation of the disconnecting switch is controlled to achieve the function of power on and off.

[0032] Reference Figure 1 , Figure 2 One end of the control lever 2 is connected to an indicator mechanism 3. Two indicator mechanisms 3 are provided, located on either side of the control lever 2. Each indicator mechanism 3 includes a circuit board 31 fixedly connected to the side wall of the switch body 1, an indicator light 32 electrically connected to the circuit board 31, and a control switch 34 for controlling the indicator light 32. The control switch 34 is fixedly connected to the side wall of the switch body 1. A fixing ring 33 is fixedly connected to the outer periphery of the control lever 2, and a pressing protrusion 331 for pressing the control switch 34 is fixedly connected to the outer periphery of the fixing ring 33. When the control lever 2 is rotated, the fixing ring 33 rotates with the control lever 2, causing the pressing protrusion 331 to press the control switch 34, thus illuminating the indicator light 32 and providing an effective indication.

[0033] Reference Figure 2 , Figure 3 Two limiting components 4 are provided on the side wall of the switch body 1. The limiting components 4 are respectively located on the opposite side of the two control switches 34. A fixing plate 13 is provided on the side of the control switch 34 away from the limiting components 4. The limiting components 4 include a balance bar 41 and a rotating shaft 42 passing through the middle of the balance bar 41. The rotating shaft 42 is rotatably connected to the side wall of the switch body 1. A locking block 43 is rotatably connected to one end of the balance bar 41 near the control switch 34, and a limiting pressure block 44 is rotatably connected to the other end. When rotating the control lever 2 to perform the opening and closing operation, pressing the locking block 43 will cause the limiting pressure block 44 to rise upward under the action of the balance bar 41, thus facilitating the rotation of the pressing protrusion 331 to press the control switch 34, causing the indicator light 32 to light up. This effectively restricts the rotation of the control lever 2 and improves the safety of use.

[0034] Reference Figure 2 , Figure 3 A reset chamber 11 is fixedly connected to the side wall of the switch body 1. The reset chamber 11 is located on the top of the limiting block 44. A fixing post 45 is connected to the top of the limiting block 44 and passes through the bottom wall of the reset chamber 11. A spring 46 is sleeved on the fixing post 45. A limiting plate 451 is circumferentially connected to the fixing post 45. One end of the spring 46 abuts against the top wall of the limiting plate 451, and the other end abuts against the inner top wall of the reset chamber 11. Under the elastic force of the spring 46, the limiting plate 451 will be subjected to a downward force, thereby driving the limiting block 44 to press down, effectively realizing the automatic reset of the limiting block 44. When the locking block 43 is not pressed, the limiting block 44 can always be maintained in the limiting position to ensure the limiting effect.

[0035] Reference Figure 2 , Figure 3The limiting block 44 has a guide groove 441 on the side opposite to the control switch 34, and a limiting protrusion 442 is fixedly connected to the side closer to the control switch 34. The guide groove 441 can effectively guide the pressing protrusion 331, so that when the control lever 2 is rotated, the pressing protrusion 331 can directly lift the limiting block 44 and make contact with the control switch 34, which can effectively improve the convenience of use; the limiting protrusion 442 can abut against the pressing protrusion 331, so that the pressing protrusion 331 cannot rotate in the opposite direction when it reaches the opening and closing position, thus ensuring the safety during opening and closing.

[0036] Reference Figure 2 , Figure 3 A guide plate 12 is fixedly connected to the side wall of the switch body 1 for the locking block 43 to pass through. The guide plate 12 can effectively restrict the movement direction of the locking block 43, so that the locking block 43 cannot rotate and can only move in the vertical direction, thereby ensuring stability during use.

[0037] Reference Figure 2 , Figure 3 The control switch 34 has a fixing plate 13 on the side opposite to the limiting protrusion 442, which abuts against the pressing protrusion 331. The fixing plate 13 is fixedly connected to the switch body 1. The fixing plate 13 provides an effective limiting effect, thereby preventing the control lever 2 from rotating excessively and causing a short circuit or open circuit, thus effectively improving electrical safety. In addition, the fixing plate 13 can cooperate with the limiting protrusion 442 to effectively limit the pressing protrusion 331, thereby improving safety.

[0038] Reference Figure 1 , Figure 2 The indicator mechanism 3 is equipped with a protective shell 5 on its outer side. The control lever 2 and the locking block 43 are both inserted through the protective shell 5, and the indicator light 32 is fixedly connected to the top wall of the protective shell 5. The protective shell 5 provides effective external protection for the indicator mechanism 3 and the limit assembly 4, preventing external dust, water droplets, etc. from affecting the operation of the indicator mechanism 3 and the limit assembly 4, effectively preventing the indicator mechanism 3 and the limit assembly 4 from rusting, and improving service life and safety.

[0039] The implementation principle of the manual operation structure of the disconnecting switch in this application embodiment is as follows: When performing the opening and closing operation, the locking block 43 is pressed. Under the action of the balance bar 41, the limiting pressure block 44 is lifted upward, thereby releasing the limiting effect. This allows the pressing protrusion 331 to trigger the control switch 34. When the control rod 2 rotates to a certain position, it abuts against the fixing plate 13. At this time, the locking block 43 re-extrudes from the protective shell 5 and the indicator light 32 lights up, indicating that the opening and closing position has been reached.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
