Embodiment
In conjunction with the foregoing description accompanying drawing the present invention is described further.
Like Fig. 1-shown in Figure 3:
Electromagnetic switch of the present invention or A.C. contactor are used latching device; The lock pin 2 and latch hook 5 of mutual correspondence are arranged, and lock pin 2 is arranged on the adhesive armature 1, and latch hook 5 is connected on the snap close base 3 through bearing pin 4 longitudinally; The top connection of latch hook 5 leans out transverse slat 16; Leaning out transverse slat 16 belows has the towed release electromagnet 7 that is fixed on the snap close base 3, and the iron core top of towed release electromagnet 7 is provided with hanging axis 17, leans out transverse slat 16 and is provided with corresponding microscler adjusting lifting hole(eyelet); Hanging axis 17 places microscler adjusting lifting hole(eyelet); The iron core of realizing towed release electromagnet 7 is lifted on and leans out on the transverse slat 16, and towed release electromagnet 7 one sides of latch hook 5 are provided with and lean out arm 6, lean out between arm 6 and the snap close base 3 and are provided with latch hook stage clip 8.Many times snap close base 3 can omit, can be directly with electromagnetic switch base double as.
Operation principle:
Moving adhesive armature 1 is inhaled in 14 energisings of adhesive magnet, and electromagnetic switch or A.C. contactor are closed a floodgate; Lock pin 2 hooks latch hook 5 simultaneously; Latch hook stage clip 8 guarantees firmly hooking of lock pin 2 and latch hook 5, keeps "on" position and stable, also is in "on" position after 14 outages of adhesive magnet always.When towed release electromagnet 7 energisings, iron core moves down, and pulling leans out transverse slat 16 and moves down, and makes latch hook 5 throw off the fixing of lock pin 2, under the effect of stand spring 11, will move bridge bracket 10 and upspring, and electromagnetic switch or A.C. contactor are broken off.
Equipped hand gear can be realized manual operation, and hand gear is made up of handle, finger rotating shaft 13 and colter key plier pole 9; The inner colter key plier poles 9 that connect of finger rotating shaft 13, the other end of colter key plier pole 9 connects finger, establishes pin-shifting hole leaning out on the arm 6; Finger places pin-shifting hole, and finger rotating shaft 13 outer ends connect handle.
Operation principle:
Under power down mode, when needing to break off electromagnetic switch or A.C. contactor, can pull handle; Finger rotating shaft 13 is rotated, and stirs colter key plier pole 9, thereby finger is stirred and leant out arm 6; Make latch hook 5 throw off the fixing of lock pin 2; Under the effect of stand spring 11, will move bridge bracket 10 and upspring, electromagnetic switch or A.C. contactor are broken off.
As shown in Figure 4:
The same basically among primary structure and Fig. 2; Just the release electromagnet structure is different; Towed release electromagnet is replaced by cylindricality release electromagnet 19; Leaning out on the transverse slat 18 and need not having established microscler adjusting lifting hole(eyelet) of this moment leans out the armature that transverse slat 18 is directly made the cylindricality release electromagnet, applicable cases and shown in Figure 1 basic identical.
Operation principle:
Moving adhesive armature is inhaled in the energising of adhesive magnet, and electromagnetic switch or A.C. contactor are closed a floodgate; Lock pin hooks latch hook 5 simultaneously; Latch hook stage clip 8 guarantees firmly hooking of lock pin and latch hook 5, keeps "on" position and stable, also is in "on" position after 14 outages of adhesive magnet always.When cylindricality release electromagnet 19 energising, inhale and movingly lean out transverse slat 18 and move down, make latch hook 5 throw off the fixing of lock pins, under the effect of stand spring, will move bridge bracket and upspring, electromagnetic switch or A.C. contactor are broken off.
Equipped hand gear can be realized manual operation, when having a power failure, uses, and situation is the same.
