For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of electromagnetic lock of manual operation mechanism of disconnecting switch; Comprise the sealing box body that base plate and stainless steel cage are formed; Its innovative point is: be respectively equipped with latch mechanism, contactor and hand-operating unlocking mechanism in the said box body: latch mechanism comprises holder, alignment pin, back-moving spring and operating grip; The holder that the center has pin-and-hole is fixed on the base plate; Alignment pin places in the pin-and-hole, and the back-moving spring that alignment pin is ejected the box body front side wall also is housed in the pin-and-hole, the end of alignment pin be located at holder operating grip outer and that stretch out the box body rear wall and be connected; Alignment pin ejects the box body front side wall and stretches into the isolating switch operating mechanism and realize the locking of isolating switch operating mechanism under the effect of back-moving spring, outwards spur operating grip and make and realize the release of isolating switch operating mechanism in the alignment pin withdrawal pin-and-hole; Contactor has the convexity and the mechanical linkage switch that stretch out the contactor housing; Mechanical linkage switch and protruding mechanical linkage; Convexity is arranged in a side of latch mechanism operating grip; It stretches out at non-energising or mechanical linkage switch and stretches out under the state and pin operating grip, at energising or the mechanical linkage switch retracted mode unlocking operation handle of withdrawing down; Hand-operating unlocking mechanism comprises lock, lever and unlock key; Lock is installed in the box body rear wall outside; Its lock core is positioned at the rear wall inboard, and lever is located between the mechanical linkage switch of lock core and contactor, and lever was failure to actuate when lock core was positioned at locked position of coupler; And lock core promotes the mechanical linkage switch that lever props up contactor when being positioned at unlocked position, promotes the withdrawal of mechanical linkage switch.
Further, the position that alignment pin stretches out on the said box body front side wall is provided with sealing ring.
Further, the said operating grip part of stretching out the box body rear wall is equipped with the sealing ring that is pressed on the box body rear wall.
Further, said locking is connected with rain-proof cover.
The invention has the advantages that: when normal running, through to contactor energising, make the operating grip of convexity withdrawal release latch mechanism of contactor; Manually outwards spur operating grip, make and connected alignment pin withdrawal realize the release of isolating switch operating mechanism; Thereby carry out the use of operating mechanism, after mechanism's actuating puts in place, break off the contactor power supply; Alignment pin automatically resets, and keeps the locking of alignment pin.Adopt electric life to reach 100,000 times to millions of times and be generally millions of mechanical life and carry out the keying of latch mechanism to ten million time contactor, dependable performance greatly reduces fault rate.
Can't switch on when carrying out the release of latch mechanism at emergent, no electric installation and maintenance etc., can stir lock core, make it promote the mechanical linkage switch that lever props up contactor, the release of realization latch mechanism through special-purpose unlock key.
The alignment pin extended position and the operating grip extended position that on box body, have hole all are provided with corresponding sealing ring, guarantee excellent sealing performance, improve the security reliability of this structure electromagnetic lock.
Description of drawings
Accompanying drawing is the electromagnetic lock structure sketch map of manual operation mechanism of disconnecting switch of the present invention.
The specific embodiment
Shown in accompanying drawing, comprise base plate 1, stainless steel cage 2, holder 3, alignment pin 4, back-moving spring 5, operating grip 6, sealing ring 7, sealing ring 8, contactor 9, convexity 10, mechanical linkage switch 11, lock 12, lever 13, unlock key 14.
Above-mentioned base plate 1 is formed the box body that seals with stainless steel cage 2, in box body, is respectively equipped with latch mechanism, contactor and hand-operating unlocking mechanism, and concrete structure is:
Latch mechanism comprises holder 3, alignment pin 4, back-moving spring 5, operating grip 6; Holder 3 is fixed on the base plate 1, and the end face that its center has a pin-and-hole is close to stainless steel cage 2 front side walls of box body, and alignment pin 4 places in the pin-and-hole; It can slide front and back in pin-and-hole; Also be connected with back-moving spring 5 in the pin-and-hole, this back-moving spring 5 is installed in the end of alignment pin 4, the front side wall that under its elastic force effect, alignment pin 4 is pushed up to stainless steel cage 2.Stainless steel cage 2 front side walls at this place have and the corresponding hole of holder 3 pin-and-holes, make alignment pin 4 can stretch out outside the stainless steel cage 2, and on this hole, are with sealing ring 7.Operating grip 6 is located at holder 3 rears; Its top is connected with the end of alignment pin 4; Terminal operator delthyrium from stainless steel cage 2 rear walls backward stretches out; And sealing ring 8 being installed at the shank of the operating grip that stretches out rear wall 6, sealing circle 8 props up the operator delthyrium on the rear wall under the effect of back-moving spring 5.
Hand-operating unlocking mechanism comprises lock 12, lever 13, unlock key 14, and lock 12 is installed in the rear wall outside of stainless steel cage 2, and its lock core stretches in the cover; Be positioned at the inboard of rear wall, lever 13 is installed on the base plate 1, between the mechanical linkage switch 11 of lock core and contactor; When lock core was in locked position of coupler, it did not contact with lever 13, and lock core is when being in the unlocked position; It promotes the mechanical linkage switch 11 that lever 13 props up contactor 9, promotes 11 withdrawals of mechanical linkage switch.Lock also is connected with rain-proof cover 15 on 12, avoids getting into rainwater in the keyhole or foreign material cause lock to open.
When this electromagnetic lock is specifically worked: when normal running; Through giving contactor 9 energisings, make the convexity 10 of contactor 9 withdraw the operating grip 6 of release latch mechanism; Manually outwards spur operating grip 6; Make and realize connected alignment pin 4 withdrawals the release of isolating switch operating mechanism, thereby carry out the use of operating mechanism; After mechanism's actuating puts in place, break off contactor 9 power supplys, alignment pin 4 automatically resets, and keeps the locking of alignment pin 4.
Can't switch on when carrying out the release of latch mechanism at emergent, no electric installation and maintenance etc.; Can stir the lock core of lock 12 through unlock key 14; Make it promote the mechanical linkage switch 11 that lever 13 props up contactor 9; Realize the release of latch mechanism, and then carry out the action of latch mechanism, realize the release of isolating switch operating mechanism.
