Description

Technical Field

[0001] The utility model particularly relates to an operating mechanism of an isolating switch. Background Art

[0002] In the prior art, the operating mechanism utilizes a dual-link, sector-shaped member. The sector-shaped member has a movable hole. The two connecting rods include a first link and a second link. A fixed pin is fixed to one end of the first link, extending into and moving relative to the movable hole. The other end of the first link engages with the second link, forming a linkage. The second link is sleeved with a spring. A driving member (the component that engages with the handle) is linked to the end of the sector away from the fixed pin. A movable pin connects the first and second links. This movable pin engages a push plate, which in turn engages a slider located below (which houses a dynamic contact assembly). Rotation of the driving member drives the sector, causing the sidewalls of the movable hole to contact the fixed pin, triggering the movement of the first link. The first and second links work together to store energy in the spring. When the spring passes a dead point, it quickly resets, causing the movable pin to move the push plate, completing an opening and closing operation.

[0003] The problem with this structure is that the first connecting rod part is located below the fan-shaped part, which causes the torque to overlap. The structural setting is unreasonable, the distance from the driving part to the movable hole is long, and the driving process is more difficult. Moreover, this design increases the width of the entire isolating switch, resulting in an increase in the volume of the entire isolating switch. Utility Model Content

[0038] Example 1:

[0039] An operating mechanism for an isolating switch, such as the attached Figure 1-7 As shown, the operating mechanism is installed in the housing 100, and the operating mechanism is used to cooperate with the slider 11 to form the opening and closing effects of the entire disconnector. How the slider 11 realizes opening and closing is a prior art, so it will not be described in detail in this embodiment.

[0040] The operating mechanism includes:

[0041] The swinging member 12 is provided with a rotating shaft portion 121 and a flat plate portion 122. The rotating shaft portion 121 is connected to the flat plate portion 122, and the rotating shaft portion 121 is specifically connected to the middle area of the flat plate portion 122. In this embodiment, the swinging member 12 is an integral member, and the rotating shaft portion 121 and the flat plate portion 122 are both part of the swinging member 12. The rotating shaft portion 121 is used to cooperate with the handle. Here, the rotating shaft portion 121 can be a square handle, or it can be other structures. The flat plate portion 122 is provided with a first movable hole 1221 and a second movable hole 1222. The first movable hole 1221 and the second movable hole 1222 are respectively arranged on both sides of the rotating shaft portion 121, and the swinging member 12 rotates relative to the shell 100. Here, the first movable hole 1221 and the second movable hole 1222 can be long holes or arc holes.

[0042] The first connecting rod assembly, the first fixing pin 13 and the second fixing pin 14 are fixed at both ends of the first connecting rod assembly, the first fixing pin 13 passes through the first movable hole 1221 and slides relative to the first movable hole 1221, the second fixing pin 14 passes through the second movable hole 1222 and slides relative to the second movable hole 1222. It should be noted here that the diameter of the first fixing pin 13 is adapted to the width of the first movable hole 1221, and it can only move in one direction. Similarly, the diameter of the second fixing pin 14 is also adapted to the width of the second movable hole 1222.

[0043] The second connecting rod assembly is fixed with the elastic member 15, and the second connecting rod assembly is provided with a third movable hole 181. The end of the second connecting rod assembly away from the first connecting rod assembly rotates relative to the housing 100. In this embodiment, the rotating shaft portion 121 and the end of the second connecting rod assembly that is rotatably connected to the housing 100 are respectively disposed on both sides of the transmission member 16.

[0044] The third fixed pin 19 is connected to the first connecting rod assembly. The third fixed pin 19 passes through the third movable hole 181 and slides relative to the third movable hole 181. The elastic member 15 is located on the movement trajectory of the third fixed pin 19. When the first connecting rod assembly is actuated, the third fixed pin 19 will slide in the third movable hole 181 and squeeze the elastic member 15 at the same time. When the elastic member 15 reaches the dead point, the entire connecting rod structure is in a balanced state. When passing the dead point, the elastic member 15 quickly resets, driving the third fixed pin 19 to move.

[0045] Transmission member 16 engages with slider 11. The upper end of transmission member 16 engages with third fixing pin 19, and the lower end of transmission member 16 engages with slider 11 to form a linkage effect. Transmission member 16 and slider 11 can be connected by plug-in connection or bolt connection. The third fixing pin 19 cooperates with transmission member 16 to drive transmission member 16 to move.

[0046] With this structural arrangement, when the handle cooperates with the rotating shaft portion 121, it drives the swing member 12 to move. Through the cooperation of the swing member 12, the first connecting rod assembly, and the second connecting rod assembly, the third fixed pin 19 drives the transmission member 16 to move, thereby achieving the opening and closing operation of the entire disconnector. Compared with the prior art, the swing member 12 is provided with two movable holes, which cooperate with the first connecting rod assembly respectively, increasing the main force arm, reducing the operating force, and facilitating the operation of the handle. At the same time, it also shortens the linear distance between the swing member 12 and the rotating shaft portion 121, thereby reducing the width of the entire disconnector and correspondingly reducing the volume of the entire disconnector.

[0047] Specifically, as attached Figure 1-6 As shown, the transmission member 16 is provided with two extension walls 161 arranged in opposite directions, and the extension walls 161 are located on the movement trajectory of the third fixed pin 19. The provision of the extension walls 161 forms a coordinated effect with the third fixed pin 19. When the third fixed pin 19 moves, the third fixed pin 19 and the extension walls 161 abut against each other to drive the transmission member 16 to move, thereby achieving a switching effect. In this embodiment, the extension walls 161 are located on the left and right sides of the upper end of the transmission member 16, that is, one extension wall 161 is located on the left and the other extension wall 161 is located on the right. The two extension walls 161 can be arranged non-parallel or parallel. Here, the upper end of the transmission member 16 can also form a concave cavity structure, and the side walls of the concave cavity are all located on the movement trajectory of the third fixed pin 19. In addition, the transmission member 16 can also be provided with a trajectory groove, and the coordination effect of the trajectory groove and the third fixed pin 19 is formed.

[0048] Specifically, the first movable hole 1221 and the second movable hole 1222 are arranged opposite to each other, so that the force is more evenly distributed and the stability is better.

[0049] Specifically, as attached Figure 4-6 As shown, the second connecting rod assembly includes a second connecting rod 18, two baffles 20, and a third movable hole 181 provided in the second connecting rod 18. One end of the second connecting rod 18 is pivotally connected to the housing 100, and the other end of the second connecting rod 18 engages with the first connecting rod assembly. An elastic member 15 is sleeved onto the second connecting rod 18, along with two baffles 20. The ends of the elastic member 15 respectively abut against the two baffles 20. The arrangement of the baffles 20 and the second connecting rod 18 simplifies the processing of each component and reduces processing costs. The baffle 20 adjacent to the third fixing pin 19 abuts against the third fixing pin 19. When the third fixing pin 19 moves, the third fixing pin 19 drives the baffle 20 and the elastic member 15 to move. Here, the elastic member 15 may be a spring. Alternatively, the second connecting rod 18 and, specifically, one baffle 20, may be integrally formed. In addition, the baffle 20 may also be provided, that is, the third fixing pin 19 is against the elastic member 15, and the rotational connection between the second connecting rod 18 and the shell 100 is against the other end of the elastic member 15. The function of the baffle 20 is to increase the contact area and improve the energy storage and release effects.

[0050] Specifically, as attached Figure 4-6 As shown, the second connecting rod 18 is provided with a stopper 182, which is located on the side wall of the second connecting rod 18. One of the blocking pieces 20 abuts against the stopper 182. Specifically, the blocking piece 20 abuts against the third fixing pin 19 and cooperates with the stopper 182 to abut against the stopper 182. The provision of the stopper 182 creates a limiting effect, preventing the blocking piece 20 from falling off.

[0051] Specifically, as attached Figure 4-6 As shown, the first connecting rod assembly includes at least two first connecting rods 17, and two adjacent first connecting rods 17 are arranged in parallel up and down, and the first fixing pin 13 and the second fixing pin 14 connect and fix all the first connecting rods 17. The cooperation of multiple first connecting rods 17 improves the strength of the first connecting rod assembly. In this embodiment, the number of first connecting rods 17 is described as two, and the two first connecting rods 17 are arranged in parallel up and down. In this embodiment, the first connecting rod 17 is approximately a T-shaped structure. It should also be noted here that a hole is also provided on the first connecting rod 17, specifically, the swinging member 12 passes through the hole to cooperate with the housing 100, forming a rotational connection effect.

[0052] Specifically, as attached Figure 1-7 As shown, one of the swinging member 12 and the housing 100 is provided with a connecting shaft 21, and the other of the swinging member 12 and the housing 100 is provided with a connecting hole 22 that cooperates with the connecting shaft 21. The connecting shaft 21 and the connecting hole 22 cooperate to achieve relative rotation. In this embodiment, the swinging member 12 is provided with the connecting shaft 21, which is located below the flat plate portion 122 and is coaxial with the rotating shaft portion 121.

[0053] Specifically, the swing member 12 is provided with a connecting shaft 21, the housing 100 is provided with a connecting column 23, and the connecting hole 22 is provided on the connecting column 23. The provision of the connecting column 23 increases strength and improves the stability of the connection between the connecting shaft 21 and the connecting column 23.

[0054] Specifically, as attached Figure 1 、 4 As shown, the shaft portion 121 is provided with an indicator 24. The provision of the indicator 24 creates an indication effect. The indicator 24 can be a color, shape, pattern, text, etc. In this embodiment, the indicator 24 is a pattern indicator, specifically an arrow.

[0055] Specifically, an auxiliary switch 25 is further included, and the auxiliary switch 25 is located on the motion track of the transmission member 16. The setting of the auxiliary switch 25 forms a communication control effect, and it can be known whether the switch is in the open state or the closed state at this time.

[0056] Specifically, the housing 100 includes an upper cover 26 and a cover plate 27. These two components cooperate to form a housing chamber 101, which houses the operating mechanism. A connecting post 23 is located on the top surface of the cover plate 27. The lower end of the transmission member 16 extends through the cover plate 27 to engage with the slider 11. A rotating shaft 121 extends through the upper cover 26 to the exterior, where it engages with the handle.

[0057] Specifically, when the handle cooperates with the rotating shaft portion 121, driving the swing member 12 to rotate, when the first fixed pin 13 abuts against the side wall of the first movable hole 1221, and the second fixed pin 14 abuts against the side wall of the second movable hole 1222, the swing member 12 will drive the first connecting rod 17 to move. At this time, the third fixed pin 19 will also move accordingly. While the third fixed pin 19 moves at the upper end of the transmission member 16, it will squeeze the elastic member 15 and also drive the second connecting rod 18 to rotate. When a dead point is formed between them, a balance point is reached, and the rotation continues. After passing the dead point, the elastic member 15 quickly resets, driving the third fixed pin 19 to move, and the third fixed pin 19 drives the transmission member 16 to move, achieving the effect of opening or closing the switch. The operation process of opening and closing the switch here is similar, the difference is that the rotation direction is different.

[0058] Example 2:

[0059] An operating mechanism for an isolating switch, such as the attached Figure 8As shown, the difference between Example 2 and Example 1 is that the baffle 20 is provided with a clamping portion 201, and the number of clamping portions 201 is two or more. In this embodiment, the elastic member 15 is a spring, so the clamping portion 201 extends along the axial direction of the spring into the interior of the spring and abuts against the inner side wall of the spring, forming a counteracting and fixing effect. The remaining portion of the baffle 20 abuts against the end of the elastic member 15, which can better achieve the driving effect of the elastic member 15. In this embodiment, the shape and size of the clamping portion 201 can be adjusted according to actual needs.
