Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. Furthermore, although terms used in the present invention are selected from publicly known and commonly used terms, some terms mentioned in the present specification may be selected by the applicant at his or her discretion, the detailed meanings of which are described in relevant parts of the description herein. Furthermore, it is required that the present invention is understood, not simply by the actual terms used but by the meaning of each term lying within.
The basic principle and preferred embodiments of the invention are discussed in more detail with reference to fig. 1, 2 and 3. The grounding switch comprises a switch body and an operating mechanism, wherein the operating mechanism controls the main shaft 1 to rotate so as to enable the switch body to perform switching-on or switching-off, and as shown in the figure, the operating mechanism of the grounding switch mainly comprises: a driving part 10, a transmission part 20 and an elastic part 30. The transmission component 20 comprises a transmission gear 22 and a crank arm 24, the driving component 10 can drive the transmission gear 22 to rotate, one end of the crank arm 24 is provided with a shaft hole 241 which is clamped with the main shaft so as to drive the main shaft 1 to rotate through the shaft hole 241, the other end of the crank arm 24 is pin-connected with the first pin 26, the crank arm 24 is also provided with a stirring piece 243 protruding out of the surface of the crank arm, and the transmission gear 22 can drive the crank arm 24 to move through the cooperation of the stirring piece 243. One end of the elastic member 30 is connected to the crank arm 24 by the first pin 26, and the other end of the elastic member 30 is pinned to the second pin 32 to allow the elastic member 30 to rotate around the second pin 32, and the second pin 32 is fixed to the operating mechanism. By adopting the mechanical structure of the transmission part 20 and the matching connection of the transmission part 20, the driving part 10 and the elastic part, the mechanical complexity and the cost can be reduced, the higher transmission efficiency can be realized, and the whole volume of the operating mechanism can be reduced.
The driving part 10 may include: a motor 12, a gearbox 14 and a drive gear 16. The motor 12 with the gear box 14 is connected with the driving gear 16 through a flat key, in the embodiment shown in fig. 1, the driving gear 16 adopts a pinion, the transmission gear 22 adopts a large gear, the driving gear 16 and the transmission gear 22 are matched to form a group of gear pairs, and the motor 12 drives the driving gear 16 to rotate so as to drive the transmission gear 22 to rotate. By using the gear box 14 as a decelerator of the motor 12 and by using a transmission structure of a motor-driven large gear with a decelerator, higher transmission accuracy and higher transmission efficiency can be achieved.
In a specific embodiment, the transmission gear 22 is disposed coaxially with the spindle 1, and it should be noted that the transmission gear 22 is disposed coaxially with the spindle 1 only, and the transmission gear 22 itself cannot drive the spindle 1 to rotate through its center. The shaft hole 241 of the crank arm 24 may be, for example, a hexagonal shaft hole structure matching the outer contour of the spindle 1, and the shaft hole 241 may be engaged with the spindle 1, so that the crank arm 24 may drive the spindle 1 to rotate through the shaft hole 241.
In the preferred embodiment shown in fig. 1 and 3, the transmission gear 22 is provided with a circular arc guide hole 221, and the striking member 243 is inserted into the circular arc guide hole 221 to allow the striking member 243 to move along the circular arc guide hole 221. Toggle 243 protruding from the surface of lever 24 is provided, and toggle 243 is located between shaft hole 241 and first pin 26 as shown in fig. 1 and 2. Specifically, toggle 243 may be integrally formed with lever 24, such as by integral injection molding or integral casting. Alternatively, in another embodiment, it may be secured to the lever 24 using a welding process, and the toggle 243 may be, for example, a toggle bolt. The transmission gear 22 can drive the crank arm 24 to move through cooperation with the stirring member 243, specifically, in this embodiment, the transmission gear 22 slowly rotates clockwise from the initial position shown in fig. 1 under the drive of the driving component 10, the circular arc guide hole 221 on the transmission gear 22 also slowly rotates clockwise, and the crank arm 24 and the stirring member 243 thereof are stationary relative to the housing of the grounding switch device, so as to ensure the relative movement between the stirring member 243 and the circular arc guide hole 221, the circular arc guide hole 221 adopts a long kidney-shaped structure as shown in fig. 1. The circular arc guide hole 221 structure is adopted to realize the pushing function of the transmission gear 22 to the crank arm 24, so that the number of parts of the transmission part 20 is saved, the space is saved, and the cost is reduced.
Specifically, in the present invention, the striking member 243 is inserted into the circular arc guide hole 221, and the right end of the inner side of the circular arc guide hole 221 is gradually close to the striking member 243; when the right end of the inner side of the circular arc guide hole 221 contacts the striking member 243, the circular arc guide hole 221 of the transmission gear 22 abuts against the striking member 243, so as to drive the crank arm 24 to slowly rotate clockwise, and during this slow rotation, the lower end of the crank arm 24 gradually compresses the elastic member 30 downward through the first pin 26. That is, when the driving part 10 continues to rotate in one direction from the initial position, the driving part 10 drives the transmission part 20 to continuously compress the elastic part 30, and the elastic part 30 is continuously compressed up to the maximum compression position. For example, in another embodiment shown in fig. 1, the transmission gear 22 is slowly rotated clockwise from the initial position shown in fig. 1 under the driving of the driving component 10, after the crank arm 24 rotates a certain angle, the first pin 26, the second pin 32 and the main shaft 1 are located in the same straight line, when the first pin 26, the second pin 32 and the main shaft 1 are located in the same straight line, the elastic component 30 is located in the maximum compression position, this position is the dead point position, when the crank arm 24 continues to rotate past the dead point position under the action of inertia force, the elastic component 30 is quickly released in a rebound manner, so as to push the crank arm 24 and the main shaft 1 to quickly rotate, so as to realize the closing operation. In addition, in the same way, in the opening process, the transmission member 20 rotates in the counterclockwise direction, the crank arm 24 is pushed by the transmission gear 22 along with the toggle member 243 to rotate counterclockwise slowly, so as to compress the elastic member 30, and after the elastic member 30 rotates past the dead point position, the crank arm 24 and the spindle 1 are pushed to rotate rapidly, so as to realize the opening operation. That is, the elastic member 30 rapidly rebounds after passing through the maximum compression position, so as to drive the transmission member 20 to move, thereby controlling the spindle 1 to rotate, so that the switch body performs switching on or off.
As a preferred embodiment, the elastic member 30 shown in fig. 2 mainly includes: a second pin 32, a guide bar 34, a spring 36 and a first spring support 38. As shown in fig. 3, one end of the guide rod 34 is connected to the second pin 32, the guide rod 34 is rotatable about the second pin 32, and the spring 36 is coaxially sleeved outside the guide rod 34. The first spring support 38 is fixed to the end of the guide rod 34 near the second pin 32, and abuts against the bottom end of the spring 36, and the spring support 38 plays a role in fixing and protecting, so that the spring 36 is not interfered with other components in the housing when compressed. The cooperation of the guide rod 34 and the spring 36 effectively avoids the left-right swing of the spring 36 during downward compression or upward rebound, so that the movement of the elastic component 30 is more stable, and the transmission efficiency is ensured. Still further, the elastic member 30 further includes: a second spring support 39. The second spring supporter 39 and the first spring supporter 38 are disposed opposite to each other, one end of the second spring supporter 39 is pinned with the first pin 26, the other end is abutted against the top end of the spring 36, and the second spring supporter 39 is adapted to slide along the outside of the guide bar 34 under the guide of the guide bar 34 to compress or release the spring 36. As shown in fig. 3, the second pin 32 is fixed to the housing of the ground switching device by a screw connection. The second spring support 39 slides downwards at a low speed along the guide rod 34 under the thrust of the first pin 26, so that the compression of the spring 36 is realized, after a certain angle is passed through a dead point, the spring 36 is released to spring open, and the second spring support 39 is pushed to slide upwards at a high speed along the guide rod 34, so that the release of energy is realized. The guide rod 34, the first spring support 38 and the second spring support 39 are connected through shaft holes in a matched mode, and the left-right swing of the spring 36 during downward compression or upward rebound is effectively avoided. The guide rod 34 rotates within a certain angular range centering on the second pin 32, ensuring that the spring 36 moves within a controllable range. The spring member 30 is formed by assembling a plurality of simple parts, and the whole volume is small, so that the space required by the spring 36 for telescopic movement is smaller.
In fig. 1, the grounding switch device comprises a main switch body, a secondary control system and an operating mechanism, and the integration degree of a mechanism box is high. The secondary control system positioned on the right side of the mechanism box shell comprises an auxiliary switch and a position indicator which are coaxially arranged, the auxiliary switch and the position indicator share a rotating shaft, and a transmission chain is simpler.
In summary, the novel structure of the design of the invention reduces the cost of the grounding switch device. In addition, through the cooperation of the driving part, the transmission part and the elastic part, higher transmission efficiency can be realized, and the occupied volume of the operating mechanism is reduced.
