Summary of the invention
Locking mechanism according to the present invention comprises universal driving shaft, and it can present two positions (be respectively and reset position and trigger position), and the triggering of described locking mechanism is delivered to the lock of circuit-breaker.
Finally, it comprises mechanism and resets button, and it can move between two settling positions (be respectively and reset position and trigger position), and during reseting, resists return device and slide.
The locking mechanism right according to the present invention is characterized in that:
Reset button and adjustable core to be actuated to do parallel translation motion, and be such as arranged so that the motion of sliding part drives universal driving shaft respectively along two rightabouts and along the direction translational motion perpendicular to its direction of motion;
Ratchet is rotatably connected to sliding part by spring element; sliding part described in described spring element bias voltage; to set up the interlock with mechanical system; described mechanical system is for realizing the reversible transition of the translational motion of button and sliding part, and described interlock makes sliding part to reset towards it in motion process of position at button and resists return device motion;
During triggering, adjustable core acts on ratchet to interrupt described interlock; on the one hand cause by the reverse movement of described return device towards the sliding part of retainer bias voltage, the position of causing button to turn back under return device is on the impact of described button to be on the other hand triggered;
The reverse movement of sliding part and button turn back to the position be triggered and are placed in the position that can restart with the interlock of ratchet by making for reversely turning round the mechanical system become.
This structure is very favorable, because which provide very short kinematic chain, comprise dual translation/rotation/translative movement, and it is by allowing to reconfigure lock, and no matter how thus guarantee correct operation, as described in detail later the position of sliding part.
More specifically, mechanical system for the reversible transition of the aggregate motion of button and sliding part comprises middle rotary platen, described middle rotary platen between two points relative to housing pivotable and be mechanically connected to button on the one hand by dual interlock and be mechanically connected to sliding part on the other hand between two retainers, by being rotatably connected to the trigger of sliding part, described dual interlock makes the translational motion of button reversibly change the rotary motion of described platen into and make the rotary motion of described platen reversibly change the translational motion of sliding part (4) into.Described trigger (14) and rotating ratchet (16) comprise corresponding profile, corresponding profile is provided with the first surface part of the motion perpendicular to sliding part (4), allow reseting first support of period along described direction of moving, described ratchet end is placed on the track of adjustable core, its motion makes ratchet pivotable and release supports, the reverse movement of sliding part and button is caused under the impact of their corresponding return device, it is facing each other that the aggregate motion of trigger and intermediate disc makes first surface part be placed in again.
This structure is particularly advantageous, because rotating ratchet and trigger are positioned on sliding part, so trigger translational motion, and more easily control their relevant positions at the stage of reseting and triggering instance subsequently, relate in a word and allow them turn back to their positions relative to each other to allow to reset.In fact, when sliding part returns towards its retainer during triggering, the interlock between rotating ratchet and trigger must can be re-established potentially, and the existence of described interlock makes it possible to reconfigure lock subsequently.This interlock of terminal allows return device lock to be turned back to its position be triggered, and the motion of various parts can make it reconfigure certainly and no matter the position of sliding part is how.

Embodiment
With reference to accompanying drawing, specifically Fig. 1 a to 1g, support and comprise cross-shaped part (crosspiece) 1 according to the module (block) of locking mechanism of the present invention, described cross-shaped part comprises again midfeather 2 and base portion 3, sliding part 4 path shift that edge is limited in one direction by retainer 5 on base portion.Reset in the pipe 8 of button 7 in the midfeather 2 being formed at cross-shaped part 1 by guiding ground translation.This button 7 can be resisted the return device of Compress Spring 30 formation and be actuated downwards.The rotatable intermediate disc 9 of driven in translation of button 7, described platen is provided with projection 10(and sees Fig. 2), described projection is freely positioned at the oblong opening 11 being arranged in the lower end reseting button 7.Meanwhile, projection 10 is moved along in the semi arch part of the circular open 12 in the surface being formed in pipe 8.
Rotary platen 9 has the second projection 13 on its another surface (i.e. the surface of sliding part 4 side), and described second projection presents the position being arranged in the oblong opening 14' that trigger 14 is formed.
This trigger 14 is included in the nose 15 of its upper end, and described nose is the dual support of the teeth groove 31 of the ratchet 16 rotatably installed by the pivot 17 on sliding part 4.
Should notice that trigger 14 is also rotatably installed by the pivot 18 on described sliding part 4.Return spring 6 is bias voltage ratchet 16 along clockwise direction.Equally, sliding part 4 is contacted (see figure 3) to pushing back with retainer 5 by return device 19.
In the midfeather of cross-shaped part 1, actuator 20 is orientated as parallel with reseting button 7.In fact this is a kind of electromagnet, and its winding 21 is around adjustable core 22, and when adjustable core has a unbalanced situation in the conductor current wanting protected circuit, (at it with when being not equal to zero) moves downward.This movement resistance (rearm) branch 23a of spring 23 of configuring and occurring again, and its another branch 23b is connected to sliding part 4.In shielded circuit without any defect, permanent magnet (not shown) makes it adjustable core 22 can be remained on its rest position.
Sliding part 4 supports universal driving shaft (linking shaft) 24, and when having difference defect on the line, described universal driving shaft directly or be set to the circuit-breaker lock that triggers side by side by connecting rod transmission system.Therefore it give prominence to from the housing of difference trigger equipment, to cooperate with circuit-breaker side by side.
It should be noted that as previously mentioned, the translation of sliding part 4 allows actuating of several micro switch, such as, supply power to electronic cards, and checks the state (configure or do not configure) of lock.Thus, specifically, projection 28' is set to drive the opening and closing reflecting sliding part 4 position of micro-contact site 27 in the stage of reseting.Equally, make it possible to actuate a switch from the outstanding and projection (lug) 28 movable window 29 of sliding part 4, described switch sends and shows that the signal of lock state is shown in Fig. 2.
Operation of the present invention is as follows: reseting user spring 30 resisted by button 7 apply pressure so that when reconfiguring product, rotary platen 9 is driven (see figure 2) by the projection 10 being arranged in oblong opening 11.Platen 9 is pivotably connected to the midfeather 2 of cross-shaped part 1, and above-mentioned specific contact site 10/ oblong opening 11 STATEMENT OF FEDERALLY SPONSORED and allow translational motion to the transformation of rotary motion.Due to this guiding, on the opposite side of midfeather 2, be fixed to platen described in platen 9(to be housed in oblong opening 14') contact site 13 when it is advanced along oblong opening 14' by the right side bias voltage trigger 14 of trigger 14 towards figure, as shown in Figure 1 b, and therefore drive whole sliding part 4, because by the nose 15 in the teeth groove 31 that is applied to described ratchet 16, trigger 14 is carried on rotating ratchet 16.Resist the translation that spring 19 applies sliding part 4 in this case.
After reseting, therefore lock is in the stable state be configured of Fig. 1 b, and due to the existence of spring 19, sliding part 4/ rotating ratchet 16/ trigger 14 assembly applies power on the contact site 13 of rotary platen 9.In the upper position (reaching this position in this condition) of described contact site 13, this power produces moment of torsion, and described moment of torsion applies in the counterclockwise direction for platen 9, because it applies below the pivot axis of described platen.And then, reset its return device 30(that button 7 is used in toggle position namely relative in the upper position of figure) on rotary platen 9, apply power, produce the moment of torsion applied in opposite direction, namely along clockwise direction, because it is applied to the left side of the described pivot axis of platen 9.
The moment of torsion produced by sliding part 4/ ratchet 16/ trigger 14 assembly is greater than the moment of torsion reseted button 7 and produce, rotary platen 9 is maintained at upper position, namely contact site 13 is positioned at the low portion of the oblong opening 14' of trigger member 14, as Fig. 1 b illustrates.
Reset button 7 and be therefore also maintained at upper position, and sliding part 4 is being reseted in button, in this case towards the left side of figure.In this position, configure according to locking mechanism of the present invention, and difference block (differential block) is therefore ready to play a role.Contact site 27 have relative to Fig. 1 a through change position.
In this static position, the power be applied on trigger 14 trends towards allowing it rotate in the counterclockwise direction, and be applied to the spring 6 that rotating ratchet 16(is particularly applied to it) on power trend towards making it be rotated in a clockwise direction, dual support is applied on nose 15/ teeth groove 31 linkage structure set up, namely one be supported on on the surface of the path parallel of button 7 and one be supported on the surface parallel with base portion 3, prevent it from rotating and guarantee the locking of thus described lock.
It should be noted that this position at sliding part 4, the spring 23 reconfigured no longer applies any effect in adjustable core 22, and described adjustable core is attracted by permanent magnet and it is very high and can not have any contact with the end of branch 23a.This effect neither be necessary, because remain on configuration (height) position due to the adjustable core 22 that exists of permanent magnet.
When there being difference defect, actuator 20 is controlled by electronic cards, thus adjustable core 22 declines towards sliding part 4.The spring 23 that this movement resistance reconfigures realizes, at least in its ending phase, as illustrated in figure 1 c.
Adjustable core 22 overlaps with an end (left part of Fig. 1 c) of rotating ratchet 16, and its opposing spring 6 is rotated counterclockwise.Double bracing STATEMENT OF FEDERALLY SPONSORED is present at nose 15 place, and trigger 14 is removed, and the balance that power is formed is changed, because mechanical linkage is disconnected.The spring 19 of sliding part 4 is subsequently by the right side bias voltage of described sliding part 4 towards Fig. 1 c.
Be in the action of the return device 30 reseting button 7 on the other hand owing to releasing energy from spring 19 on the one hand, be applied to relative direction for mechanism translational motion being converted to rotary motion.Substantially, because rotary platen 9 is reseting pivotable (described rising is (see Fig. 1 f) that the effect of the return device of described button 7 causes) along clockwise direction under the impact that button 7 rises, owing to being placed in opening 14' relative to the return force contact site 13 applied by spring 19, described contact site 13 leaves the bottom of opening 14' subsequently at the motion move under influence of component 14, continue sliding of its other end towards opening 14' subsequently, so trigger 14 pivotally 18 pivotables first in the counterclockwise direction.
In fact, when contact site 13 reaches certain height, its action on trigger 14 by conversely, and makes the clockwise pivotable of the latter.If sliding part 4 reaches retainer 5, then itself is placed in the position shown in Fig. 1 g by component 14, vertical oblong slit, after slightly having risen described ratchet 16 when trigger 14 turns clockwise, nose 15 is again through the teeth groove 31 of rotating ratchet 16.Ratchet by this spring of its return spring 6(support by its branch on sliding part 4) actuate time, ratchet 16 is biased to turn clockwise, to re-establish dual support interlock between nose 15 and ratchet 16 when nose 15 has moved across the teeth groove of ratchet 16.
When sliding part 4 does not arrive retainer 5, contact site 13 is given prominence to from intermediate disc 9, under the impact of the return device of button 7, it rotates terminal, and axis 18 no longer with the alignment of orientation being arranged essentially parallel to described button 7 direct of travel, but follow well azimuth: nose 15 is moved subsequently and is left the teeth groove of ratchet 16, guarantees can reconfigure in all cases.As shown in Figure 4.A benefit of this structure is the functional stabilization that it produces.
In the other end of sliding part 4, due to the motion of sliding part 4 (see Fig. 1 e to 1g) to the right, the spring 23 reconfigured is extruded by housing by branch 23b, and its pivotable thus contact adjustable core 22 its branch 23a make described core upwards towards be set to hold it in rest position permanent magnet motion.And then universal driving shaft 24 is fixed to sliding part, described sliding part is by the right side translation towards figure, and it applies direct or indirect effect on the lock of the relevant circuit-breaker be triggered.Arm 25 turns back to its original position, and reuses spring 26 and make contact site 27 opening and closing.
Lock is in the position be triggered now, and the stayed surface of nose 15 and teeth groove 31 reorientate to allow to reconfigure.
