Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described.
Can work independently from lock unit, also can work together, but the interlocking unit need be become could work at least by two interlocking unit combination with a plurality of interlocking unit combination.
Power supply unit switch with the smoke exhaust special use is embodiment, its be by one from lock unit, the power supply unit switches that three interlocking unit combination become.Each distance between cells is according to instructions for use, can reach by number and the width that changes the intermediate isolating cover, and cage is exempted from greasy dirt (also can) for the cleaning that guarantees switch, as Fig. 4, shown in Figure 5.
Go up to cylindrical, button 1 roof pressure that has bipod down is connected with iron tongue piece 3 at front end, the rear end is connected with on the upper surface of travel(l)ing rest 2 of permanent-magnet steel 4, travel(l)ing rest 2 posterior end bipods, lead-out tablet 6 is arranged in the insertion, the lockhole limit has in the corresponding breach of movable contact spring 8 rear portion dual-sides of snap close 7, moving contact 9 and lead-out tablet 11 on movable contact spring 8 front ends, fixed contact 10 on 12 cooperates, locking plate 15 upper ends are arc, be fixed between housing 16 upper end inwall ribs with awl bolt 13, the lower end have vertical with locking plate and with the convex edge 14 of tongue piece form fit, insert in the lockhole of movable contact spring 8 buttons 7 with lock the locking plate lower end, housing right upper medial wall place also is fixed with iron block 5, is used for travel(l)ing rest, permanent-magnet steel resets, and covers cover plate 20 and just constitutes from lock unit, as Fig. 1, Fig. 2, shown in Figure 4
In the interlocking unit, movable contact spring 8 ' on the big lock hole limit have the turnover be 90 ° riser 7 ', lock dog 19 is made by insulating material, the centre of last newel post has square through hole to be used to pass square shaft 18, it is stairstepping that 17 1 sides are detained on the top of lower end, a relative side is the inclined-plane, lock dog 19 upper ends one side groove internal fixation has an end of back-moving spring 24, end places on the housing wall in addition, also fixedly be mated the cross section in housing 16 internal tongues 3 ' pivot region and be circular limited bolt 25, the same with in lock unit of remaining parts and connection thereof, as shown in Figure 3.
With the cross section is the square hole that square square shaft 18 passes the first interlocking unit, the second interlocking unit, lock dog 19 upper ends, the 3rd interlocking unit, each interlocking unit is linked into an integrated entity, pass large and small through hole on lock unit, the first interlocking unit, the second interlocking unit, the 3rd interlocking unit and cage 22 from upper and lower end respectively with screw 21, alignment pin 23, be fixed into one with nut, as shown in Figure 4.
The illumination of self-locking unit controls smoke exhaust, work independently not have and get in touch with the interlocking unit, as shown in Figure 2, a, be in the beginning armed state from lock unit, moving contact 9 on the movable contact spring 8 contacts with the fixed contact 10 of lead-out tablet 12 lower surfaces, and locking plate 15 does not pin movable contact spring, and tongue piece 3 is by permanent-magnet steel 4 controls, make the tip of the tongue angle of tongue piece be in an armed state, promptly in the back edge of movable contact spring lockhole; B, finger are to pressing down button 1, button bipod roof pressure travel(l)ing rest 2, make permanent-magnet steel 4 rear portions break away from fixedly iron block 5, and be fulcrum with the travel(l)ing rest rear lower, with the tip of the tongue of tongue piece 3 to pressing down, because of stopping, the movable contact spring lockhole can not move forward, force the movable contact spring forward position to move down, moving contact 9 bottoms are contacted with the fixed contact 10 of lead-out tablet 11 upper surfaces, the convex edge 14 on the locking plate just in time contacts with the snap close 7 on movable contact spring lockhole limit at this moment, carry out line transfer, at this moment open illuminating lamp; C, when finger leaves button 1 because the effect of permanent-magnet steel 4 and iron block 5, button is resetted and on move, the tip of the tongue of tongue piece leaves edge behind the movable contact spring lockhole, contact with convex edge 14 on the locking plate and to be self-locking state, illuminating lamp is still bright, prepares for movable contact spring resets to discharge; D, once more to pressing down button 1, the permanent-magnet steel rear portion breaks away from iron block 5, travel(l)ing rest drives the tip of the tongue of tongue piece to pressing down, because the convex edge of locking plate stops, can not move down, can only push locking plate 15 forward open by the tip of the tongue of tongue piece, make the tip of the tongue leave the snap close 7 on movable contact spring lockhole limit, make movable contact spring 8 release that resets by elastic reaction, moving contact is thrown off the fixed contact 10 on the lead-out tablet 11 simultaneously, contact with fixed contact 10 on the lead-out tablet 12 and carries out the circuit switching, at this moment close illuminating lamp, finger unclamps button 1 and returns to Fig. 2 a armed state, and illuminating lamp still is in closed condition, finishes the course of work with self-locking and break-make conversion.
That interlocking unit controls oil-fume extractor motor rotates is fast, slow, stop.If the first interlocking unit A is for stopping, the second interlocking unit B is fast, and the 3rd interlocking unit C be slow, (the 3rd interlocking unit C action picture among the figure, principle is identical with the second interlocking unit B).
Need earlier the second interlocking unit B to be discharged during first interlocking unit A work, the first interlocking unit A could work then, at this moment point to the button 1 that presses down on the first interlocking unit A, by the tongue piece on the support lock dog 19 being put on forward makes a movement, there are enough amplitudes of oscillation to pass to other unit by square shaft, by the limited bolts 25 in tongue piece 3 ' the run into housing 16 the tip of the tongue is tilted upward, top button 17 lock dog 19 under the effect of spring 24 power that skids off on the lock dog 19 resets, as Fig. 6 a
1Shown in.At this moment the second interlocking unit B is in and waits to discharge as Fig. 6 a
2, by the square shaft on the lock dog 19 18 the lock dog rotatory force is passed to the connected lock dog of the second interlocking unit B, movable contact spring is threaded off, the release that resets of the second interlocking unit B is as Fig. 6 b
2Shown in, travel(l)ing rest 2 withstands riser 7 on the movable contact spring 8 ' continue to move down then, latchs until slipped into lock dog 19 snap closes by the movable contact spring lockhole by the first interlocking unit A below, as Fig. 6 b
1, bleeding off finger, button resets, and the first interlocking unit A latchs and resets, as Fig. 6 c
1, and the maintenance release of the corresponding second interlocking unit, as Fig. 6 c
2, promptly motor quits work.
Equally, also be released when originally also being in latch mode, promptly can discharge other unit, and made simultaneously to be latch mode by the unit by any one interlocking unit if any other unit.
