Below in conjunction with accompanying drawing embodiment of the present invention is described in detail.
Fig. 2 is the perspective exploded view of operating mechanism in the embodiment of the present invention.As shown in Figure 2, this operating mechanism comprises: 54, one transmission mechanisms 56 of 52, one sliding parts of a driving shaft (be illustrated as a drive among the figure, but it also can comprise other associated components), and an elastic mechanism 100.Wherein, driving shaft 52 can be subjected to external force and rotate, and the rotation of driving shaft 52 can drive sliding part 54 and slides along illustrated glide direction.Sliding part 54 can further drive transmission mechanism execution change action along the slip of illustrated glide direction.In Fig. 2, the driving end 44 of elastic mechanism 100 interlock that can cooperatively interact with the link 541 of sliding part 54, and thus can be in the slip of the auxiliary sliding part 54 of illustrated glide direction.In execution mode shown in Figure 2, sliding part 54 driven shafts 52 drive to slide along its glide direction, slide along its glide direction but also can drive sliding part 54 by other driving mechanism, for example: drive rod.
In execution mode shown in Figure 2, driving shaft 52 is provided with a drive link 522.Sliding part 54 be parallel to a sidewall that illustrates glide direction be provided with first the contact wall 60 contact wall 62 with second.Drive link 522 can contact respectively wall 60 and contact wall 62 with second and contact to drive the slip of sliding part 54 on the diagram glide direction with first.Transmission mechanism 56 for example can comprise a drive, and this drive is provided with a driving cog 562.In the sliding part 54 with first and second contact wall 60 is set, 62 relative sidewalls are provided with the first driving gear 70 and the second driving gear 72.Driving cog 562 can be respectively and the first driving gear 70 and the second driving gear 72 interoperations.Like this, when sliding part slides, first, second driving gear will drive respectively driving cog 562, rotate thereby drive drive, and then the rotation of drive can drive the action of other switching parts that are connected with this drive.For example when operating mechanism shown in Figure 2 was applied in the isolating switch, transmission mechanism 56 can be used for the change action of moving contact in the driving isolation switch, to realize combined floodgate or separating brake.
The below gets back in the execution mode shown in Figure 2.In Fig. 2, comprise in the elastic mechanism 100: 10, one of frameworks are 20, one connectors 30 of elastic component of compression direction distortion as described in Figure, and a driving member that can rotate around the axis 40.Wherein, connector 30 contacts for face between connector 30 and the elastic component 20 between elastic component 20 and driving member 40.Driving member 40 is provided with contact jaw 42 and driving end 44, and the link 541 of the sliding part 54 in the Surface Contact towards this driving member of contact jaw 42 and connector 30, driving end 44 and operating mechanism is connected.
Contacting between contact jaw 42 and the connector 30 preferably can be the contact of rolling.Preferably, connector 30 is provided with projection 32 towards the end face of driving member 40, because projection 32 has center height, shape that the edge is low, thereby by projection 32 is set, can be so that driving member 40 in the process of transmission, by the dead point, avoids the rotation of driving member by locked rapidly.Here, the dead point refers to that driving member 40 is compressed to the position of maximum position with elastic component, situation as shown in Figure 4, and in the case, the transmission arm of driving member is basically parallel with compression direction.Here preferably, contacting between contact jaw 42 and the projection 32 rolling friction can be set to, frictional force can be reduced, so that the rotation of driving member 40 is smooth and easy.
Two opposing sidewalls along compression direction shown in Figure 2 on the framework 10 are provided with connecting hole 14, driving member 40 is provided with axis hole 46, framework also is provided with a connecting axle 16, connecting axle 16 can insert in connecting hole 14 and the axis hole 46, so that driving member 40 can and can move along illustrated compression direction around connecting axle 16 rotations.It will be understood by those skilled in the art that the purpose that connecting axle 16 is set be for so that driving member 40 can in framework, rotate, with the elastic force of transfer elastic part and drive switching mechanism.Can also adopt in framework the crown of roll that is provided for connection for transmission spare along two opposing sidewalls of as shown in Figure 2 compression direction being connected between driving member and the framework, and driving member can move around this crown of roll rotation with along compression direction shown in Figure 2, saves and uses connecting axle 16.
In example arrangement shown in Figure 2, be connected by a coupler latch 58 between the driving end 44 of elastic mechanism 100 and the link 541 of sliding part 54.Particularly, sliding part 54 has a through hole 5412 that is preferably the waist type near on the link 541 of elastic mechanism 100, and also is provided with through hole 441 on the driving end 44 of elastic mechanism 100.After waist typed through hole 5412 contrapositions with the through hole 441 of driving end 44 and link 541, coupler latch 58 is penetrated respectively in the through hole 441 and the waist typed through hole 5412 on the link 541 on the driving end 44.Like this, coupler latch 58 has been realized cooperatively interacting between the driving end 44 of elastic mechanism 100 and the sliding part 54, but and the stored energy of transfer elastic mechanism, elastic force for example is with the slip of auxiliary sliding part 54.
Wherein, in the present embodiment, the diameter of the through hole 441 on the driving end 44 can be suitable with the diameter of coupler latch 58, and the size of waist typed through hole 5412 on glide direction need to be greater than the diameter of coupler latch 58, and the length of waist typed through hole 5412 is also greater than the diameter of coupler latch 58.Like this, driving end 44 can loosely be connected with the link 541 of sliding part 54, thereby it not only can move, move along the direction opposite with compression direction under the pressure of elastic component 20 along illustrated glide direction under the drive of sliding part 54, can also when approaching or arrive the dead point, driving member 40 slide into another sidewall of waist-shaped hole from a sidewall along the edge of waist typed through hole, thereby by the dead-centre position, avoid the pause of not expecting rapidly.Preferably, the size on glide direction of waist typed through hole 5412 can be diameter 1.5-2 times of coupler latch 58.Alternatively, the type of set through hole also can switch on driving end 44 and the link 541, that is, driving end 44 is provided with waist typed through hole, and link 541 is provided with and through hole 441 similar through holes.In addition, waist typed through hole is also replaceable to be the through hole of other types, circular port for example, slotted eye, square opening etc.Preferably, size namely has the circular arc shape in the edge opposite with compression direction greater than the lower edge of the through hole of coupler latch, so that coupler latch slides into the position of being close to another sidewall from a sidewall being close to through hole.
In execution mode shown in Figure 2, be connected by a coupler latch 58 between the driving end 44 of elastic mechanism 100 and the link 541 of sliding part 54, and, the diameter of the through hole 441 on the driving end 44 can be suitable with the diameter of coupler latch 58, and the size of waist typed through hole 5412 on glide direction need to be greater than the diameter of coupler latch 58, like this so that the link 541 of the driving end 44 of driving member 40 and sliding part 54 cooperatively interact in the mode that has idle running in glide direction.This idle running can be after elastic component 20 be compressed to maximum position, and in the situation that sliding part 54 does not slide, so that departing from the angle of compression direction, driving member 40 becomes large, like this, not only can be so that elastic component 20 can discharge stored energy in basic undamped ground behind the dead-centre position, but also so that the power that the driving end 44 of driving member 40 acts on the link 541 of sliding part 54 becomes large along the component of glide direction, increase the effect that elastic mechanism 100 auxiliary sliding parts 54 slide, improved the operating mechanism performance.Here, behind the dead-centre position, idle running so that the driving end 44 of driving member 40 do not contact with the link 541 of sliding part 54, like this, elastic component 20 can discharge stored energy under less resistance, in other execution modes of the present invention, can think to discharge to the basic undamped of elastic component 20 energy stored energy this moment.
And in other execution modes of the present invention, also can waist type shrinkage pool be set at two relative madial walls of the link 541 of sliding part 54, be provided for connecting the crown of roll of the link 541 of sliding part 54 at two relative lateral walls of the driving end 44 of driving member 40, and, the size of waist type shrinkage pool on glide direction need to be greater than the diameter of crown of roll, so also can so that the link 541 of the driving end 44 of driving member 40 and sliding part 54 cooperatively interact in the mode that has idle running in glide direction.Alternatively, two relative madial walls at the driving end 44 of driving member 40 arrange circular shrinkage hole, be provided at two relative lateral walls of the link 541 of sliding part 54 connection for transmission spare 40 driving end 44 crown of roll, and, the diameter of circular shrinkage hole is greater than the diameter of crown of roll, equally, also so that the link 541 of the driving end 44 of driving member 40 and sliding part 54 cooperatively interact in the mode that has idle running in glide direction.
In above-mentioned all execution modes, after elastic component 20 was compressed to maximum position, the idle running on this glide direction can be so that driving member 40 departs from described compression direction 5-8 degree in the situation that sliding part 54 does not slide.Preferably, deviation angle is 6 degree.
Fig. 3 to Fig. 6 has illustrated the elastic mechanism 100 auxiliary motion processes that comprise the switching device shifter change action of above-mentioned operating mechanism as an example of structure shown in Figure 2 example.But, it will be understood by those skilled in the art that, this motion process can also adopt other structures to realize, as long as take all to have on glide direction and compression direction the mode of activity surplus to cooperatively interact between the link 541 of the driving end 44 of elastic mechanism 100 and sliding part.In following Fig. 3-6, drive link 522 occurs in the X-Y plane of in the drawings restriction with the interaction of sliding part 54, in the X-Z plane that the interaction of driving cog 562 and sliding part 54 and elastic mechanism and sliding part 54 occurs to limit in the drawings.
Because coupler latch 58 inserts respectively the through hole 441 on the driving end 44, and in the waist typed through hole on the link 541 5412, the interlock so that driving end 44 and sliding part 54 cooperatively interact.And the diameter of the through hole 441 on the driving end 44 and the diameter of coupler latch 58 are suitable, and waist typed through hole 5412 on the glide direction and the size on the compression direction greater than the diameter of coupler latch 58.Like this, at the motion process of Fig. 3 Fig. 6, the motion of coupler latch 58 in waist typed through hole 5412 is equivalent to driving end 44 and moves in waist typed through hole 5412.
Fig. 3 is the structural representation that switching device shifter for example is in off state.As shown in Figure 3, the elastic component 20 of elastic mechanism is in uncompressed state, and the contact jaw 42 of driving member 40 contacts with connector 30, and the drive link 522 of driving shaft 52 contacts wall 60 contacts with first, and the driving cog 562 of drive 56 contacts with the first driving gear 70.
When needs switch to opening state with switching device shifter, by applying external force, so that driving shaft 52 in X-Y plane along direction rotation shown in the arrow among Fig. 3, rotate thereby drive drive link 522, the rotation of drive link 522 can promote sliding part 54 and slide along X-axis negative sense among Fig. 3.At this moment, the driving end 44 of elastic mechanism 100 is close to the first side of the waist typed through hole 5412 on the link 541 of sliding part 54, and the first side is the side near the X-axis forward.As shown in Figure 3, sliding part 54 promotes the driving end 44 of driving member 40 along the slip of X-axis negative sense, thereby so that whole driving member 40 rotates take connecting axle 16 as axle, simultaneously whole driving member 40 20 moves along illustrated compression direction towards elastic component, make contact jaw 42 pushing connectors 30, thus so that elastic component 20 compressions.
The moment shown in Figure 4 is that contact jaw 42 contacts with the lowermost end (or top, center) of the projection 32 of connector 30, this moment, elastic component 20 reached compression,metal-to-metal position, contact jaw 42 and driving end 44 are in along on the same straight line on the diagram compression direction, and this position is called the dead point in the handoff procedure.At this moment, the driving end 44 of elastic mechanism 100 still is close to the first side of the waist typed through hole 5412 on the link 541 of sliding part 54.
External force continuation effect driving shaft 52, thus drive link 522 continues to promote the first contact wall 60, so that sliding part 54 continues to slide along the X-axis negative sense.As shown in Figure 5, the contact jaw 42 of driving member 40 is just by the dead point, and there is a less angle in driving member 40 with illustrated Z-direction, for example: 1 °.At this moment, because namely, there is the space in the size of waist typed through hole 5412 on glide direction between the second sidewall of waist typed through hole 5412 and the driving end 44 greater than the diameter of coupler latch 58.Wherein, the second sidewall is the sidewall of diagram near the X-axis negative sense.Under the effect of elastic component 20 elastic forces so that the link 44 of driving member 40 can be rapidly to the gap motion, until.In this process, link 44 not with the second sidewall contact of waist typed through hole 5412, elastic component 20 discharges stored energy in undamped ground substantially, can so that driving member 40 is crossed rapidly the dead point, avoid the rotation of driving member 40 by locked.And, behind the second sidewall contact of link 44 and waist typed through hole 5412, driving member 40 increases rapidly with the angle of illustrated Z-direction, for example: be increased to 7 ° from 1 °, like this, the power that link 44 acts on the second sidewall contact increases rapidly at the component of X-direction, thereby has increased the effect that elastic mechanism 100 auxiliary sliding parts 54 slide, and has improved the performance of operating mechanism.
The contact jaw 40 of driving member 40 passes through the dead point, and the contacting of the projection 32 of disengaging and connector 30, as shown in Figure 6, under the effect of the elastic force of elastic component 20, driving member 40 is rotated further around connecting axle 16, and move towards the direction away from elastic component 20 along illustrated compression direction, the driving end 44 of driving member 40 drives sliding part 54 along the negative sense slip of diagram X-axis, the drive link 522 of drive rod 52 broke away from the contact that contacts wall 60 with first and contacted wall 62 with second and contact this moment, driving cog 562 disengagings of drive 56 contact with the second driving gear 72 with contacting of the first driving gear 70, and this moment, the state of switching device shifter became opening state.
It will be understood by those skilled in the art that switching device shifter is opposite with the process of foregoing description to the motion process of off state by opening state, does not repeat them here.
Above-mentioned operating mechanism and switching device shifter thereof, because the width of the waist typed through hole 5412 of link 541 is greater than the diameter of coupler latch 58 in the sliding part 54, like this, waist typed through hole 5412 and coupler latch 58 have the space in X-direction, be that the driving end 44 of driving member 40 and the link 541 of sliding part 54 cooperatively interact in the mode that has idle running in glide direction, thereby, can so that driving member 40 is crossed rapidly the dead point, avoid the rotation of driving member 40 by locked.And, this idle running is so that the power that acts on shortly past the driving end 44 of driving member behind the dead-centre position 40 on the link 541 of sliding part 54 becomes large along the component of glide direction, increase the effect that the auxiliary sliding part of elastic mechanism slides, improved the performance of operating mechanism and switching device shifter.
Above-mentioned switching device shifter can be applicable to this needs such as isolating switch, contact-making switch to carry out having improved the performance of device for switching in the device for switching of state switching.
Above by accompanying drawing and preferred implementation the present invention has been carried out detail display and explanation, yet the invention is not restricted to the execution mode that these have disclosed, other scheme that those skilled in the art therefrom derive out is also within protection scope of the present invention.
