Summary of the invention
The object of the present invention is to provide a kind of lever and support assorted structure of circuit breaker operation mechanism, to improve stability and the useful life of operating mechanism, reduce the difficulty of processing of lever and support.
For reaching above-mentioned purpose, solution of the present invention is:
The lever of circuit breaker operation mechanism and a support assorted structure, comprise lever, support and wear-resisting positioning sleeve; Support comprises biside plate and the connector being connected biside plate, each side plate is arranged the groove rotatably contacted for lever; Lever comprises lever main body and is arranged on the rotation pin of lever main body both sides, and each rotation pin moves with bracket-rotatable the contact jaw contacted and arranges feet; Wear-resisting positioning sleeve is arranged on feet, and wear-resisting positioning sleeve rotatably contacts with the groove of side plate.
Further, groove is set to deep-slotted chip breaker, and accordingly, feet is set to curved support pin.
Further, wear-resisting positioning sleeve is the wear-resisting positioning sleeve through Technology for Heating Processing.
Further, wear-resisting positioning sleeve arranges the detent rotatably contacted with side plate groove, and the bottom of detent is contact-making surface; The contact site of side plate groove is placed between the two side of detent, and the contact site of side plate groove rotatably contacts with the contact-making surface of wear-resisting positioning sleeve.
Further, detent is set to arc detent.
Further, wear-resisting positioning sleeve arranges fixed groove, and the feet of lever rotation pin inserts and is installed in fixed groove.
Further, fixed groove is set to arc fixed groove.
After adopting such scheme, the wear-resisting positioning sleeve of the present invention is arranged on feet, wear-resisting positioning sleeve rotatably contacts with the groove of side plate, lever rotation pin of the present invention rotatably contacts with the groove of rack side plate by wear-resisting positioning sleeve, make the wearing and tearing between lever rotation pin and the groove of side plate less, improve stability and the useful life of operating mechanism.
Wear-resisting positioning sleeve, through Technology for Heating Processing, makes wear-resisting positioning sleeve resistance to wear improve further, thus can cancel the Technology for Heating Processing to lever and support, reduces the difficulty of processing of lever and support, and then cuts down finished cost.
The contact site of side plate groove is placed between the two side of detent, thus can limit the axial freedom of lever rotation pin, and lever rotation is comparatively stable.

Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in detail.
Consult shown in Fig. 1 to Fig. 6, a kind of lever of circuit breaker operation mechanism and support assorted structure, comprise lever 1, support 2 and wear-resisting positioning sleeve 3.
Support 2 comprises biside plate 21 and the connector 22 being connected biside plate 21, each side plate 21 is arranged the groove 23 rotatably contacted for lever 1.
Lever 1 comprises lever main body 11 and is arranged on the rotation pin 12 of lever main body 11 both sides, and each pin 12 that rotates arranges feet 13 with the contact jaw that support 2 rotatably contacts.Groove 23 is preferably set to deep-slotted chip breaker, and accordingly, feet 13 is preferably set to curved support pin.Certain groove 23 and feet 13 can be other structure, rotate pin 12 rotatably contact with support 2 as long as realize lever 1.
Wear-resisting positioning sleeve 3 is arranged on curved support pin 13, and wear-resisting positioning sleeve 3 rotatably contacts with the deep-slotted chip breaker 23 of side plate 21.Lever 1 rotates pin 12 and rotatably contacts by the deep-slotted chip breaker 23 of wear-resisting positioning sleeve 3 with support 2 side plate 21, and the wearing and tearing between the deep-slotted chip breaker 23 making lever 1 rotate pin 12 and side plate 21 are less, improves stability and the useful life of operating mechanism.
