The upside of dynamic component 6；Handle padlock components 5 are mounted on the upside of cover board 4；
The contact 301 of microswitch 3 is downward, and a contact frizzen 202 is hinged on stent 1, can by moving contact 301,
Connect microswitch 3；
It converts transmission parts 6 and includes master gear 601 and two conversion gears 602；Two conversion gears 602 pass through axis respectively
It is fixed between stent 1 and cover board 4；Master gear 601 includes installing plate 605 and is vertically installed in the gear of 605 downside of installing plate
Portion 609,605 upside of installing plate are equipped with a pair of of protrusion 603, raised 603 symmetrical apertured；The diameter of installing plate 605 is more than gear part
609 outer diameter；609 bottom of gear part sets cylindric installing component 604, the position of Correspondent cy linder shape installing component 604, stent 1
It is equipped with matched hole 101；The shape of corresponding installing plate 605 and position, cover board 4 are equipped with mounting hole；Installing plate 605 is pacified
In the mounting hole on cover board 4, cylindric installing component 604 is mounted in the hole 101 of stent 1, defines master gear 601
Installation site；The center of master gear 601 sets through-hole, and annular mounting groove is equipped on the outside of through-hole；Installation compression spring in annular mounting groove
608, the interior installation compression bar 607 of through-hole, compression bar 607 divides for transverse part and vertical part；Transverse part may be stuck in 608 upside of compression spring, and vertical part can pass through
Through-hole, pressing contact frizzen 202 trigger contact 301；The gear part 609 of master gear 601 circumferentially only local cloth tooth, master gear
601 can be meshed with two conversion gears 602 respectively；
There are two display units 7, and structure is identical, matches respectively with two conversion gears 602；Single display unit 7 wraps
Include display board 701, spur rack 703 and rack installing plate 702；Spur rack 703 is mounted on the side of conversion gear 602, is nibbled with it
It closes；The installation site of corresponding spur rack 703, cover board 4 are equipped with strip hole；Spur rack 703 is vertically mounted on rack installing plate 702
On, 702 upside of rack installing plate is formed with fixture block 704, and rack installing plate 702 is mounted on by fixture block 704 in strip hole, and energy
It is free to slide along strip hole；Display board 701 is fixed on fixture block 704；
Handle padlock components 5 include handle 501 and padlock plate 502；The main body of handle 501 is semicircle shape, is cut with scissors by axis pin
It is connected in the hole of protrusion 603 set on the installing plate 605 of master gear 601；The downside of handle 501 is formed with raised I；Stir hand
Handle, when making it vertically upward, raised I presses moulded rod 607, makes 1 plane of its vertical part protrusion installation site stent, pressing contact triggering
Bar 202 triggers contact 301, connects microswitch 3, shows in double point positions；501 inside of handle is slotted, for accommodating padlock
Plate 502；Padlock plate 502 is mounted in slot, can be slided in slot；When padlock plate 502 pulls out, hole and handle in padlock plate 502
Hole on 501 overlaps, for padlock.
As one embodiment of the present of invention, handle padlock components 5 further include limiting slot 503, the second compression spring 505 and interlocking
Bar 504；When padlock plate 502 leans out handle 501, the corresponding position of cover board 4 is equipped with limiting slot 503, is formed in limiting slot 503 logical
Hole, through-hole middle part are equipped with circle convex platform；Second compression spring 505 is mounted in circle convex platform；The middle part of blocking lever 504 can pass through second
Compression spring 505, lower diameter are more than the internal diameter of circle convex platform, and top is stuck in the upside of the second compression spring 505；Padlock plate 502 leans out hand
During handle 501, compressing blocking lever 504 moves downward, and 504 lower tip of blocking lever is corresponded to beyond limiting slot 503 under 4 position of cover board
Surface.The position of limiting slot 503 corresponds to the lower surface of cover board 4 and 702 installation site cover board 4 of rack installing plate is equipped with strip hole
The lower surface at place is in the same plane.
In use, two conversion gears 602 operate the divide-shut brake of common power supply and standby electricity source respectively.Such as Fig. 4 a, 4b
It is shown, it is illustrated that be double point positions, handle 501, which is dug, to be come, and the padlock plate 503 in handle 501 can be pulled on cover board 4
In limiting slot 503.As shown in Figure 4 b, padlock plate 503 subdues blocking lever 504, at this time since two indicator boards 701 are two
End, not in centre, so blocking lever 504 can be forced into the lower surface for protruding from cover board 4, circular hole and hand in padlock plate 503
Circular hole on handle 501 overlaps, can in two holes padlock.And divide position double, the raised I on handle 501 presses moulded rod
607, make 1 plane of its vertical part protrusion installation site stent, pressing contact frizzen 202 triggers contact 301, connects microswitch
3, send out signal to controller, disconnect the electric operating circuit of controller, ensure manual operation when will not electric operating, play
The effect of interlocking ensure that the safety of manual operator.
The present apparatus also has another interlock, if master gear 601 or conversion gear 602 fail, as gear breaks
It splits, causes in common power supply or stand-by power supply combined floodgate, handle 5 has still been transferred to double point positions, if energy padlock, then
Can threaten the safety of operating personnel, the interlock of the present apparatus ensure that in this case can not padlock, said below
It is bright.As shown in Fig. 7 a~c, in main power source closing position, conversion gear 602, which rotates to, is stuck in centre, if master gear 601 or
602 break of gear tooth of conversion gear, the failure of engaging of master gear 601 and conversion gear 602, handle 5 drive master gear 601 to go to
It is double to divide position, and the main power source closing position that conversion gear 602 remains in, the instruction equally engaged with conversion gear 602
Plate 701 is still within intermediate position.When at this moment pulling out padlock plate 503, blocking lever 504 can be pressed downward, and indicator board 701 corresponds to
Blocking lever 504 is blocked in the position of rack installing plate 702, causes blocking lever 504 that can not push, and such blocking lever 504 is just extension
Jam plate 503 blocks, and causes padlock plate 504 that can not extract out, also just can not padlock, it is achieved thereby that interlock.
