Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a switch opening and closing operating handle for a power distribution cabinet. Background Art

[0002] In the production process of electricity, it is often necessary to open and close the switch of the distribution cabinet. In an emergency or when the remote CRT cannot be operated, the operator needs to operate the switch of the distribution cabinet on the spot. However, this operation method requires the operator to stand directly in front of the switch compartment and operate it by hand, which has a high safety hazard, such as personal injury caused by operating errors or switch failures.

[0003] Therefore, operators usually use operating handles or operating rods to perform switch opening and closing operations. For example, CN105870818A discloses an operating rod for a power distribution cabinet, which includes a hollow insulating rod, a fastener, a power steering transmission device and a transmission shaft, wherein the transmission shaft is nested inside the insulating rod and one end is connected to the fastener through the power steering transmission device, wherein the fastener and the central axis of the transmission shaft form an angle greater than 90 degrees and less than 180 degrees, and the power steering transmission device converts the power of the transmission shaft rotating along its central axis into the power of the fastener rotating along its central axis. The fastener is driven to rotate by the transmission shaft, and then the rotation button of the leakage protector on the distribution cabinet is adjusted, without the need for manual climbing of ladders or close-range operation, and the safety is good, and it is easy to operate and carry.

[0004] However, when opening and closing the leakage protection button, CN105870818A uses the button protrusion on its rotating rod to press. Due to the setting of the angle between the vertical part and the bent part of the rotating rod, using the button protrusion to press the leakage protection button requires the operator to apply a large force to the rotating rod to press, which is time-consuming and labor-intensive, and may not be pressed in the right place.

[0029] This embodiment relates to a switch opening and closing operating handle for a power distribution cabinet, Figure 1 and Figure 2 , including an insulating shell 10, a sleeve 20, an insulating head 30, an operating handle 40 and an energy storage device 50, wherein the insulating shell 10 includes a vertical portion 11 and a horizontal portion 12, the horizontal portion 12 is located at the top of the vertical portion 11, and the horizontal portion 12 is connected to the inside of the vertical portion 11. The sleeve 20 is detachably connected to one end of the horizontal portion 12, and its interior is connected to the horizontal portion 12, and an opening 21 for sleeve-mounting a switch button is opened at one end of the sleeve 20 away from the horizontal portion 12.

[0030] The insulating head 30 is movably disposed in the horizontal portion 12 . The insulating head 30 is disposed along the length direction of the horizontal portion 12 . One end of the insulating head 30 facing the opening 21 is disposed in an arc shape. The insulating head 30 can move along the length direction of the horizontal portion 12 toward or away from the opening 21 .

[0031] The operating handle 40 is movably disposed in the vertical portion 11 . The operating handle 40 is disposed along the length direction of the vertical portion 11 . The bottom end of the operating handle 40 extends from the bottom end of the vertical portion 11 . The top end of the operating handle 40 extends upward into the horizontal portion 12 and presses against the side wall of the insulating head 30 .

[0032] The energy storage device 50 is disposed in the horizontal portion 12 and is used to provide kinetic energy to the insulating head 30 , so that when the operating handle 40 is separated from the insulating head 30 , the insulating head 30 automatically moves in a direction close to or away from the opening 21 .

[0033] Reference Figure 1 and Figure 2 In this embodiment, the insulating head 30 has an energy storage state and an energy release state. When the operating handle 40 is pressed against the side wall of the insulating head 30, the insulating head 30 is fixed in the horizontal portion 12 by the operating handle 40. At this time, the insulating head 30 is in the energy storage state. When the operating handle 40 is separated from the insulating head 30, the insulating head 30 automatically moves toward the direction close to the opening 21 under the kinetic energy provided by the energy storage device 50. At this time, the insulating head 30 is in the energy release state.

[0034] When in use, a sleeve 20 of different specifications is selected according to the switch button, the sleeve 20 is sleeved on the horizontal part 12, and then the sleeve 20 is sleeved outside the switch button. At this time, the operating handle 40 is driven to separate from the insulating head 30, so that the insulating head 30 moves toward the direction close to the opening 21 under the kinetic energy provided by the energy storage device 50, so that the insulating head 30 automatically presses the switch button, thereby realizing the opening or closing of the switch button.

[0035] In some embodiments, the energy storage device 50 includes an energy storage spring 51 disposed in the horizontal portion 12, the energy storage spring 51 is disposed along the length direction of the horizontal portion 12, one end of the energy storage spring 51 is fixedly connected to one end of the horizontal portion 12 away from the sleeve 20, and the other end of the energy storage spring 51 is fixedly connected to the insulating head 30. In a specific implementation process, the energy storage spring 51 can be wound around the outside of the insulating head 30, and the side wall of the insulating head 30 is provided with a convex point that cooperates with the end of the energy storage spring 51, so as to realize energy supply to the insulating head 30.

[0036] In some embodiments, an energy storage indicator 52 is provided at one end of the insulating head 30 facing away from the opening 21, and the energy storage indicator 52 is used to indicate the position of the insulating head 30, that is, the energy storage indicator 52 indicates the state of the insulating head 30 (energy storage state or energy release state), and a through hole is opened on the horizontal portion 12 for the energy storage indicator 52 to extend out of the horizontal portion 12.

[0037] When the energy storage indicator 52 is completely exposed from the horizontal portion 12, the distance between the insulating head 30 and the opening 21 reaches the maximum, and the energy storage spring 51 is in a compressed state, that is, the insulating head 30 is in an energy storage state. When the energy storage indicator 52 is partially exposed from the horizontal portion 12, the distance between the insulating head 30 and the opening 21 is the minimum, and the spring is in a normal state, that is, the insulating head 30 is in an energy release state.

[0038] In addition, when the insulating head 30 needs to be reset to the energy storage state, the energy storage indicator 52 can be pulled to move away from the opening 21, thereby pulling the insulating head 30 to move away from the opening 21, so as to facilitate resetting the insulating head 30 to the energy storage state.

[0039] In some embodiments, a slot 31 is provided on the insulating head 30 to cooperate with the operating handle 40, and when the top of the operating handle 40 is inserted into the slot 31, the insulating head 30 is fixed in the horizontal portion 12. That is, through the cooperation between the slot 31 and the operating handle 40, the operating handle 40 and the insulating head 30 are more closely matched, so that the insulating head 30 can be switched between the energy storage state and the energy release state by driving the operating handle 40, and the insulating head 30 is more stable in the energy storage state.

[0040] In some embodiments, a protective pad is disposed at one end of the insulating head 30 facing the opening 21. That is, by disposing the protective pad, the insulating head 30 is not likely to cause damage to the switch button when the switch button is pressed.

[0041] In some embodiments, the sleeve 20 is threadedly connected to the horizontal portion 12. By threading the sleeve 20 to the horizontal portion 12, it is more convenient to disassemble the sleeve 20 so as to adapt to switch buttons of different sizes.

[0042] In some embodiments, a clamping spring 41 is provided in the vertical portion 11, and the clamping spring 41 is provided along the length direction of the vertical portion 11. One end of the clamping spring 41 is fixedly connected to the bottom end of the vertical portion 11, and the other end of the clamping spring 41 is fixedly connected to the operating handle 40. The clamping spring 41 is used to continuously provide elastic force to the operating handle 40 so that the operating handle 40 can be clamped against the insulating head 30.

[0043] In some embodiments, one end of the operating handle 40 extending out of the vertical portion 11 is also sleeved with a pull ring 42 for facilitating pulling the operating handle 40. By pulling the pull ring 42 downward, the operating handle 40 is driven to move in a direction away from the insulating head 30 along the length direction of the vertical portion 11, so that the operating handle 40 is separated from the insulating head 30, and then the insulating head 30 is automatically moved toward the direction close to the opening 21 under the action of the energy storage device 50, and the operation is simple and convenient.

[0044] In addition, refer to Figure 1-Figure 4 This embodiment also provides an operating method for the above-mentioned distribution cabinet switch opening and closing operating handle 40, including the following steps:

[0045] 1. Check the appearance of the insulating housing 10 and make sure that the insulation is good;

[0046] 2. Pull the pull ring 42 downward to separate the operating handle 40 from the insulating head 30;

[0047] 3. Pull the energy storage indicator 52 to move the insulating head 30 toward one end of the insulating housing 10. After the insulating head 30 is in place, release the pull ring 42 to make the operating handle 40 automatically rise and snap into the slot 31 on the insulating head 30, completing the energy storage of the insulating head 30, that is, the insulating head 30 is in the energy storage state;

[0048] 4. Select a sleeve 20 of corresponding specifications according to the size of the switch button to be operated, and sleeve the sleeve 20 on the end of the horizontal portion 12 of the insulating housing 10 away from the energy storage indicator 52, and move the insulating housing 10 so that the sleeve 20 is sleeved outside the switch button;

[0049] 5. Pull the pull ring 42 downward to separate the operating handle 40 from the insulating head 30, so that the insulating head 30 is in an energy release state, that is, the insulating head 30 automatically moves toward the opening 21 of the sleeve 20 under the action of the energy storage device 50 and presses the switch button, and the operation is completed.

[0050] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
