Embodiment
Understood referring to figs. 1 to Fig. 6, the utility model：A kind of tripping mechanism, including magnetictrip body 1 and handle 4,
Push rod 3 is provided with the magnetictrip body 1, the end of push rod 3 is provided with drive link 5, and drive link 5 is coaxially fixedly installed
Poke rod 6, the side of the drive link 5 away from push rod 3 are provided with limited post 15, and limited post 15 is used for the biography to being ejected by push rod 3
The spacing handle 4 of lever 5 is provided with projection 41, described raised 41 and is arranged on the side of the end of poke rod 6, and handle 4 is also connected with
There is connecting rod 7, connecting rod 7 is U-shape structure, and connecting rod 7 connects locking device 8, and locking device 8 connects movable contact 10, institute by movable feeler lever 9
State movable contact 10 to be correspondingly arranged with stationary contact 11, and movable contact 10 and stationary contact 11 are the connecting terminal on main line 12, are led to
Cross its contact or disconnect and realize the on or off of main line 12, side connection extension spring of the movable feeler lever 9 away from push rod 3
14, it is mutually spacing by torsion spring 13 and buckle 2 between the drive link 5 and poke rod 6, the drive link 5 be provided with boss 51 and
Salient point 52 and concave-shaped arc surface 53, the boss 51 is corresponding with push rod 3, and concave-shaped arc surface 53 is located at the lower section of push rod 3, and is arranged on remote
From the side of magnetictrip body 1, concave-shaped arc surface 53 is set to prevent from passing to increase the elasticity of this section of drive link 5 at this
When lever 5 resets, big pressure is produced to push rod 3, therefore in contact or close push rod 3, the end of drive link 5 contradicts to be taken off to electromagnetism
Device body 1 is detained, now concave-shaped arc surface 53 is flexible, and protection drive link 5 damages, and while both having protected push rod 3 or protects transmission
Bar 5, increases the service life.
The side of drive link 5 and 6 buckle of poke rod, 2 spacing setting, opposite side is spacing each other by torsion spring 13, the card
Button 2 is that the breach 61 on poke rod 6 is spacing to the holding of drive link 5.
The side of drive link 5 is coaxially fixedly installed with poke rod 6, and can be rotated along the axle.
The locking device 8 includes tripping 81, clamping plate 82 and lock 83, and 83 sides of the lock are salient point 52, work as transmission
Bar 5 is by the thrust of push rod 3, and salient point 52 is to latching 83 secondary impacts, so that locking device 8 goes to act；The connecting rod 7 is buckled in jump
In one hole of button 81, the tripping 81 is fixed with clamping plate 82 by rivet coaxially slide, lock 83, clamping plate 82 and the movable contact
First 10 three is fixed by rivet coaxially slide, the clamping plate 82 and lock 83 between fixed by torsion spring it is spacing, clamping plate 82 with
It is fixedly connected between movable feeler lever 9.
Movable contact 10 contacts with stationary contact 11 during 12 normally of main line, and the state of release apparatus is as shown in Figure 2；
When electric current exceedes setting electric current or other fault currents occur in main line 12, the push rod 3 in magnetictrip body 1 pushes up
Go out, drive link 5 is hit by push rod 3, is moved to away from the direction of electrical apparatus release body 1, the salient point 52 on drive link 5 is to latching 83 2 times
Hit, so that locking device 8 goes to act, drive movable contact 11 to realize main line 12 away from stationary contact 12 by movable feeler lever 9
Cut-out；When main line 12 repairs normal, handle 4 is pulled, drives locking device 8 to act by connecting rod 7, and then pass through movable feeler lever
9 drive movable contacts 11 are connected close to stationary contact 12, sound contact, main line 12, while handle 4 is pulled, its projection 41
Poke rod 6 is driven to be rotated around its fixing axle, it is spacing due to being provided between poke rod 6 and drive link 5, therefore drive link 5 also turns therewith
Dynamic, the rotation of drive link 5 pushes push rod 3 and resetted.
It is complicated using inflexible problem, the dropout machine that the utility model effectively improves existing tripping mechanism
