Description

Technical Field

[0001] This utility model relates to the field of power technology, and in particular to a drive shaft operating structure for an operating mechanism. Background Technology

[0002] Power distribution cabinets are devices used for power distribution, control and protection in power systems. They are widely used in power distribution stations and prefabricated substations in load centers such as urban residential areas, high-rise buildings, large public buildings, factories and enterprises.

[0003] The operating mechanism of the power cabinet is the core component for controlling the opening and closing of the switch. Its main functions are: (1) Opening and closing control: driving the contacts of the switch to open and close through mechanical or electric means to realize the opening and closing of the circuit; (2) Safety interlock: cooperating with grounding switches, disconnecting switches, etc., to prevent misoperation through mechanical interlock; (3) Fault protection: in case of overcurrent or short circuit, the tripping mechanism quickly opens the circuit to isolate the fault circuit.

[0004] The drive shaft of the operating mechanism is usually a hexagonal shaft. When operating manually, a hexagonal handle needs to be inserted into the hexagonal shaft. During the insertion process, the hexagonal handle needs to be repeatedly adjusted so that each side is aligned with each side of the hexagonal shaft before it can be inserted. The insertion operation is inconvenient, time-consuming and laborious, and there is also a possibility that the insertion may not be successful, which will prevent the operating mechanism from being driven quickly. Utility Model Content

[0005] To address the shortcomings of existing manual operation methods in operating mechanisms, the applicant provides a rationally structured drive shaft operating structure for the operating mechanism, which facilitates drive shaft operation and ensures quick operation of the operating mechanism.

[0006] The technical solution adopted in this utility model is as follows: An operating structure for a drive shaft of an operating mechanism includes an adapter and an operating component. The adapter is inserted into the drive shaft, and the operating component is located on one side of the adapter and can be close to or away from the adapter. When the operating component is away from the adapter, it is disengaged from the adapter; when the operating component is close to the adapter, it is engaged with the adapter. The adapter is provided with a pin, and the operating component is provided with an operating disc. When the drive shaft is operated, the pin engages with the operating disc.

[0007] As a further improvement to the above technical solution: The control panel has corresponding insertion holes for the pins, and the pins are inserted into the insertion holes.

[0008] The insertion hole is a fan-shaped hole, and the arc length of the insertion hole is greater than the diameter of the insertion pin.

[0009] The arc of the connector is 60 to 150°.

[0010] The operating panel of the operating component is connected to the connecting shaft, which is connected to a component that can drive its movement; the connecting shaft includes a round shaft portion and a polygonal shaft portion, with the polygonal shaft portion connected to the operating panel.

[0011] On the control panel, a polygonal hole is opened on the corresponding polygonal shaft part, and the polygonal shaft part is inserted into the polygonal hole.

[0012] The control panel is equipped with an outer ring located outside the insertion hole; when the insertion pin is inserted into the insertion hole, the axial height of the insertion pin extending into the control panel is less than or equal to the axial height of the outer ring.

[0013] The connector pins of the adapter are set on the adapter block, which is inserted into the drive shaft; the adapter block and the drive shaft are respectively provided with connector pins on opposite sides.

[0014] The operating components are installed on the cabinet door and can move with the cabinet door.

[0015] The drive shaft is either a round shaft or a polygonal square shaft.

[0016] The beneficial effects of this utility model are as follows: This utility model provides a connecting component on the drive shaft of the operating mechanism and a corresponding operating component on the outer cabinet. The connecting component is connected to the operating panel of the operating component via a pin for transmission, which makes operation convenient and quick, facilitates the operation of the drive shaft, and ensures the quick drive of the operating mechanism.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, this utility model provides an operating structure for operating the drive shaft 10 of the operating mechanism 100. The operating structure is disposed on the drive shaft 10, and through this operating structure, the drive shaft 10 can be operated conveniently and quickly, ensuring the rapid driving of the operating mechanism 100. The drive shaft 10 can be a hexagonal shaft or other types of shafts, such as a round shaft or other polygonal shafts; in this embodiment, a hexagonal shaft is used as an example for explanation.

[0024] like Figure 1 , Figure 2 As shown, the operating structure includes a connecting component 1 and an operating component 2. The connecting component 1 is fixedly inserted into the drive shaft 10, and the operating component 2 is installed on the cabinet door of the outer cabinet (not shown in the figure). The operating component 2 can move with the cabinet door; when the cabinet door is opened, the operating component 2 disengages from the connecting component 1 (see reference). Figure 2 a) After the cabinet door is closed, the operating component 2 and the adapter component 1 are plugged in and engaged (see reference). Figure 2 (b) Rotating the operating component 2 can drive the adapter component 1 to rotate, thereby operating the drive shaft 10. In other embodiments, the operating component 2 can also be set on other components that can move it closer to or away from the adapter component 1. When the operating component 2 moves away from the adapter component 1, it is disengaged from the adapter component 1. When the operating component 2 moves closer to the adapter component 1, it is engaged with the adapter component 1.

[0025] like Figure 2 As shown, the adapter component 1 includes an adapter block 11 and a connector pin 12. The adapter block 11 is fixedly inserted into the drive shaft 10, and the connector pin 12 is disposed on the adapter block 11 and extends forward toward the operating component 2. In this embodiment, two connector pins 12 are provided extending from the side of the adapter block 11 facing the operating component 2, and the connector pins 12 are distributed on opposite sides of the drive shaft 10. The adapter block 11 is engaged with the operating component 2 through the connector pins 12 located on opposite sides of the drive shaft 10. The operating component 2 applies force to the adapter block 11 from opposite sides through the connector pins 12, driving the adapter block 11 and the drive shaft 10 to rotate. The force on the adapter block 11 and the drive shaft 10 is more even, and the operation of the drive shaft 10 is more stable and reliable.

[0026] like Figure 2 , Figure 3As shown, the operating component 2 includes an operating panel 21 and a connecting shaft 22. The operating panel 21 is connected to one end of the connecting shaft 22 near the adapter component 1, and the other end of the connecting shaft 22 is connected to the cabinet door of the outer cabinet. The operating panel 21 has a corresponding insertion hole 211 for the insertion pin 12. When the operating component 2 is inserted into the adapter component 1, the insertion pin 12 is inserted into the insertion hole 211. The insertion hole 211 is a fan-shaped hole, and the arc length of the insertion hole 211 is greater than the diameter of the insertion pin 12, providing ample insertion space for the insertion pin 12 and facilitating its insertion. The arc of the insertion hole 211 is 60–150°, providing sufficient insertion space for the insertion pin 12 while ensuring that the operating panel 21 has sufficient width to guarantee operational reliability.

[0027] like Figure 3 As shown, the connecting shaft 22 of the operating component 2 includes a round shaft portion 221 and a polygonal shaft portion 222. The round shaft portion 221 is connected to the cabinet door, and the polygonal shaft portion 222 is connected to the operating panel 21. A polygonal hole 212 is formed on the operating panel 21 corresponding to the polygonal shaft portion 222, and the polygonal shaft portion 222 is inserted into the polygonal hole 212. In this embodiment, the polygonal hole 212 is a square hole, and the polygonal shaft portion 222 is a square shaft. The operating panel 21 and the connecting shaft 22 transmit torque through the square hole and the square shaft, thereby improving the stability and reliability of operation.

[0028] like Figure 3 As shown, an outer ring 213 is provided on the outer side of the operating disk 21, extending forward toward the circular shaft portion 221. The outer ring 213 is located outside the insertion hole 211. When the insertion pin 12 is inserted into the insertion hole 211, the axial height of the insertion pin 12 extending into the operating disk 21 is less than or equal to the axial height of the outer ring 213. The outer ring 213 can improve the strength of the operating disk 21, improve the stability and reliability of operation, and also enclose the insertion pin 12 within its axial range, providing protection for the insertion pin 12, preventing other components from interfering with the movement of the insertion pin 12, and ensuring the stability and reliability of operation.

[0029] This utility model provides a connecting component 1 on the drive shaft 10 of the operating mechanism 100, and correspondingly provides an operating component 2 on the outer cabinet. The connecting component 1 is connected to the operating panel 21 of the operating component 2 through a plug pin 12 for transmission. The operation is convenient and quick, which facilitates the operation of the drive shaft 10 and ensures the quick drive of the operating mechanism 100.

[0030] The above description is an explanation of the present utility model and not a limitation thereof. The present utility model can be modified in any form without departing from its spirit.
