Embodiment
In order to make the public can fully understand technical spirit of the present utility model and beneficial effect; applicant will describe in detail embodiment of the present utility model below by reference to the accompanying drawings; but applicant is not the restriction to technical scheme to the description of embodiment, anyly changes in the form rather than substance and all should be considered as protection range of the present utility model according to the utility model design.
Refer to Fig. 1, Fig. 2 and Fig. 3, the utility model relates to a kind of breaker open operation lever, comprise hub setting bar 12, the a pair of stripe board that faces each other and be arranged in parallel 11, described hub setting bar 12 is through a pair of stripe board 11, a pair of stripe board 11 is fixed with a pivot pin 14 in one end of length direction, this pivot pin 14 comprises the external part and the card cap 143 that stretch out a pair of stripe board 11, described external part and card cap 143 are positioned at the two ends of pivot pin 14, spaced apart first jump-ring slot 141 that is provided with on described external part, the second jump-ring slot 142, and the wherein stripe board place that the first jump-ring slot 141 is close in a pair of stripe board 11 arranges, the first described jump-ring slot 141, the second jump-ring slot 142 respectively with the first jump ring 171 of one group of jump ring 17, the second jump ring 172 coordinates, on described external part, be also arranged with an axle sleeve 16, described axle sleeve 16 comprises an axle sleeve matrix 162, described axle sleeve matrix 162 is extended with shade 163 and forms a container cavity 161 to described stripe board 11, axle sleeve matrix 162 is between the first jump ring 171 and the second jump ring 172, described container cavity 161 is for holding the first described jump ring 171.
Because the external part of pivot pin 14 offers the first jump-ring slot 141 at the wherein stripe board place being close in a pair of stripe board 11, this first jump-ring slot 141 coordinates with the first jump ring 171 in one group of jump ring 17, and cooperate with card cap 143, thereby define a pair of stripe board 11.Simultaneously, due to coordinating of the second jump-ring slot 142 and the second jump ring 172 in one group of jump ring 17, axle sleeve matrix 162 is between the first jump ring 171 and the second jump ring 172, described axle sleeve matrix 162 is extended with shade 163 and forms a container cavity 161 to described stripe board 11, thereby the second jump ring 172 can pass through axle sleeve 16, and cooperate with card cap 143, limit stripe board 11.At work, after the second jump ring 172 in one group of jump ring 17 first comes off, the first jump ring 171 still can cooperate and limit described pivot pin 14 with card cap 143 described point brake lever rod, thereby pivot pin 14 can work on, and has finally improved the life-span of operating mechanism.Divide brake lever rod at work, may occur the situation of the second, after the first jump ring 171 first comes off, the second jump ring 172 cooperates and limits pivot pin 14 by axle sleeve 16 and with card cap 143, thereby pivot pin 14 can work on, and has finally improved the life-span of operating mechanism.In the second situation, because the container cavity 161 of axle sleeve 16 is wrapped in the first jump ring 171 outsides, now the first jump ring 171 is subject to the constraint of container cavity 161 to be still in service position, can not fall to circuit breaker inner and unpredictable danger occurs.
One side side of described axle sleeve 16 and the first jump ring 171 is fitted in respectively the wherein outside of a stripe board in a pair of stripe board 11.The mode of this kind of laminating, can prevent the play of pivot pin 14.
Described jump ring 17 is preferably circle, and described container cavity 161 is preferably the circle matching with described jump ring.
On described pivot pin 14, be also arranged with a cooperation axle sleeve 15, this cooperation axle sleeve 15 is between described a pair of stripe board 11.Described cooperation axle sleeve 15 carrys out the in-house connecting rod conversion of stop operation by shock.And described cooperation axle sleeve 15 defines the spacing between a pair of stripe board 11, thereby can guarantee that whole point of brake lever rod is stable, work reliably.
