Fig. 2 is structural front view of the present utility model.
Fig. 3 is structure left view of the present utility model.
Fig. 4 is structure vertical view of the present utility model.
In the drawings, 1, chain holder 2, latch lever 3, returning spring 4, spacing pad 5, chain drive plate 6, chain drive rod 7, roller 8, limiting plate 9, positioning baffle.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, the utility model is achieved like this, a kind of circuit breaker interlocking gear for console mode circuit breaker, it comprises chain holder 1 and is positioned at the latch lever 2 of chain holder, its structure is, it also comprises the limiting plate 8 and chain drive plate 5 that are positioned at chain holder 1, one end of described latch lever 2 is connected on the sidewall of chain holder 1, the other end is through after limiting plate 8, again with chain drive plate 5 Structure deformation, chain drive plate 5 is fixed on chain drive rod 6, latch lever 2 peripheral ring between limiting plate 8 and the sidewall of chain holder 1 is wound with returning spring 3, described latch lever 2 stretches out outside the sidewall of chain holder 1 under the driving of chain drive plate 5.During use, chain holder 1 can be welded and fixed to appropriate location, when circuit breaker shakes test position, chain drive plate 5 is driven to swing by the rotation of chain drive rod 6, chain drive plate 5 has the motive torque perpendicular to chain drive rod 6 central axis, and to drive latch lever 2 to stretch out to chain holder 1 outer wall, the part of being stretched out chain holder 1 outer wall by latch lever 2 pins circuit-breaker testing position, operation is very easy, and check man can keep in repair circuit breaker safely.The releasing process as above reverse operating of circuit breaker interlocking gear, after unblock, circuit breaker can shake service position.
Too much in order to prevent in the chain holder 1 of latch lever 2 indentation, can be fixed with on latch lever 2 and coordinate with limiting plate 8, for limiting the spacing pad 4 of latch lever 2 indentation chain holder 1 internal limit position, like this when interlocking gear unlocks, inside indentation under the effect of returning spring 3, when spacing pad 4 touches limiting plate 8, latch lever 2 indentation is complete.
Described latch lever 2 end and chain drive plate 5 Structure deformation realize like this, one end that latch lever 2 contacts with chain drive plate 5 is provided with roller 7, and when chain drive plate 5 swings, roller 7 contacts with chain drive plate 5, and along chain drive plate 5 surface scrolls, drive latch lever 2 to move.
Described chain holder 1 internal fixtion has the positioning baffle 9 swinging extreme angles for limiting chain drive plate 5; Positioning baffle 9 is fixed on just on chain holder 1 medial surface of latch lever 2, and after unblock, chain drive plate 5 swings back home position, and now the extreme position of chain drive plate 5 just contacts with positioning baffle 9.
In addition, chain drive plate 5 is spirally connected or is welded on chain drive rod 6, one end of described chain drive rod 6 is connected on the sidewall of chain holder 1, according to the structural requirement of chain drive plate 5, can suitably adopt the fixed form being spirally connected or welding, when the chain drive plate 5 of the frequent dismounting of needs, then adopt screw connection manner, otherwise adopt the good welding manner of structural strength.
In order to improve the area of chain drive plate 5 and latch lever 2 Structure deformation, improve stability when driving, chain drive plate 5 can be designed to strip or fan-shaped, and along the circumferencial direction that chain drive plate 5 swings; Because chain drive plate 5 to be unconventionally rigidly connected with latch lever 2, do not need connector, not only part reduces, and also reduces the difficulty requirement of assembling.
