The content of the invention
It is an object of the invention to provide a kind of lever of circuit breaker operation mechanism and support assorted structure, to improve operation
The difficulty of processing of the stability and service life of mechanism, reduction lever and support.
To reach above-mentioned purpose, solution of the invention is：
A kind of lever of circuit breaker operation mechanism and support assorted structure, including lever, support and wear-resisting positioning sleeve；Support
The groove being rotatably in contact for lever is set on connector including biside plate and connection biside plate, each side plate；Lever includes thick stick
Bar main body and the rotation pin for being arranged on lever main body both sides, it is each to rotate the contact jaw setting support that pin is rotatably in contact with support
Pin；Wear-resisting positioning is set in support feet, and wear-resisting positioning sleeve is rotatably in contact with the groove of side plate.
Further, groove is set to deep-slotted chip breaker, accordingly, and support feet is set to curved support pin.
Further, wear-resisting positioning sleeve is the wear-resisting positioning sleeve Jing Guo Technology for Heating Processing.
Further, wear-resisting positioning sleeve sets the detent being rotatably in contact with side plate groove, and the bottom of detent is
Contact surface；The contact site of side plate groove is placed between the two side of detent, and the contact site of side plate groove connects with wear-resisting positioning sleeve
Contacting surface is rotatably in contact.
Further, detent is set to arc detent.
Further, wear-resisting positioning sleeve sets fixed groove, and the support feet insertion of lever rotation pin is installed in fixed groove.
Further, fixed groove is set to arc fixed groove.
After such scheme, the wear-resisting positioning of the present invention is set in support feet, and the groove of wear-resisting positioning sleeve and side plate can
Rotation is in contact, and lever rotation pin of the present invention is rotatably in contact by wear-resisting positioning sleeve with the groove of rack side plate so that lever
The abrasion rotated between pin and the groove of side plate is smaller, improves the stability and service life of operating mechanism.
Wear-resisting positioning sleeve passes through Technology for Heating Processing so that wear-resisting positioning sleeve wearability is further improved, so as to cancel
To the Technology for Heating Processing of lever and support, the difficulty of processing of reduction lever and support, and then reduce processing cost.
The contact site of side plate groove is placed between the two side of detent, so as to limit the axial direction of lever rotation pin certainly
By spending, lever rotation is relatively stable.

Label declaration
The lever main body 11 of lever 1
Rotate the support feet 13 of pin 12
The side plate 21 of support 2
The groove 23 of connector 22
The wear-resisting detent 31 of positioning sleeve 3

Embodiment
The present invention is described in detail below in conjunction with drawings and the specific embodiments.
Refering to shown in Fig. 1 to Fig. 6, a kind of lever of circuit breaker operation mechanism and support assorted structure, including lever 1, branch
Frame 2 and wear-resisting positioning sleeve 3.
Support 2 includes setting rotatable for lever 1 on the connector 22 of biside plate 21 and connection biside plate 21, each side plate 21
The groove 23 being in contact.
Lever 1 includes lever main body 11 and is arranged on the rotation pin 12 of the both sides of lever main body 11, each to rotate pin 12 and support 2
The contact jaw being rotatably in contact sets support feet 13.Groove 23 is preferably arranged to deep-slotted chip breaker, accordingly, and support feet 13 is preferably provided with
For curved support pin.Certain groove 23 and support feet 13 can be other structures, as long as realizing that lever 1 rotates pin 12 can with support 2
Rotation is in contact.
Wear-resisting positioning sleeve 3 is arranged on curved support pin 13, the rotatable phase of deep-slotted chip breaker 23 of wear-resisting positioning sleeve 3 and side plate 21
