Accompanying drawing explanation
Fig. 1 is the installation diagram of a kind of ratchet-type circuit breaker cart rocking handle provided by the invention;
Fig. 2 is the cutaway view of a kind of ratchet-type circuit breaker cart rocking handle provided by the invention.
Embodiment
For making the present invention become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
As shown in Figure 1, a kind of ratchet-type circuit breaker cart rocking handle provided by the invention is made up of parts such as handlebar 1, arm bar 2, pawl base 3, connector 4, upper ratchet 5, lower ratchet 6, poke rod 7, the upper decorative pearl on top of an official cap 8, the lower decorative pearl on top of an official cap 9, spring 10, upper pin 11, lower bearing pin 12 and stopper rings 13.
During storage, handlebar 1, arm bar 2, pawl base 3, connector 4 are drawn into " I " font, can deposit with circuit breaker bottom a cylinder in.During use, handlebar 1 bends in 90 ° with arm bar 2, arm bar 2 with pawl base 3, and whole rocking handle, in " Z " font, can carry out shake operation.Handlebar 1 is for holding handle during shake, and one end girdling a groove, be convenient to rocking handle provided by the invention to take out from storage cylinder, the other end is articulation joint, hinged with arm bar 2.Arm bar 2 is arm of force when rocking handle shakes, and all there is articulation joint at two ends, one end and handlebar 1 hinged, the other end and pawl base 3 hinged.Pawl base 3 one end is articulation joint, hinged with arm bar 2, and groove and lower groove are opened in other end both sides, and upper ratchet 5 and lower ratchet 6 are placed in groove and lower groove respectively, porose in the middle of this end of pawl base 3, for placing poke rod 7.Two ends, left and right outside upper ratchet 5 and lower ratchet 6 have one section of upper pawl teeth section and lower pawl teeth section respectively, middle porose, insert upper pin 11 and lower bearing pin 12 respectively, ratchet 5 and lower ratchet 6 can be rotated around upper pin 11 and lower bearing pin 12 respectively.There is through hole one end of poke rod 7, and in the upper decorative pearl on top of an official cap 8 and the lower decorative pearl on top of an official cap 9 and spring 10 are placed in, its other end also has through hole, for settling stopper ring 13.Poke rod 7 has two effects: the first, be the direction of operating controlling rocking handle by rotating poke rod 7, another plays a supportive role to connector 4.One end of the upper decorative pearl on top of an official cap 8 and the lower decorative pearl on top of an official cap 9 is tack blind hole, and for entangling spring 10, the other end is hemispherical head, is respectively used to the inner side of withstanding ratchet 5 and lower ratchet 6.There is internal gear one end of connector 4, is enclosed within pawl base 3, coordinates with upper pawl teeth section and lower pawl teeth section, and its other end is turret head, coordinates with circuit breaker drawer base handle hole, and the centre of connector 4 is porose, and poke rod 7 runs through wherein, can rotate around it.Stopper ring 13 is triangle steel ring, has two effects: the first, drive poke rod 7 to rotate by operation stopper ring 13, thus control the direction of operating of rocking handle; The second, block connector 4, prevent connector 4 from deviating from.
Composition graphs 2, the specific embodiment of the invention course of work is: pawl base 3 spacing, on the coordinating of curved surface inside ratchet 5 and lower ratchet 6 and the upper decorative pearl on top of an official cap 8 and the lower decorative pearl on top of an official cap 9 hemispherical head, spring 10 elastic force effect under, poke rod 7 only has two stable location statuss, correspond to clockwise and counterclockwise two direction of operating, without loss of generality, appoint and get a kind of state description.Under the effect of spring 10 elastic force, the upper decorative pearl on top of an official cap 8 and the lower decorative pearl on top of an official cap 9 make ratchet 5 and lower ratchet 6 deflect an angle all clockwise, pawl teeth section and pawl teeth section under the right side of lower ratchet 6 on the left side of ratchet 5 is made to contact the internal gear of connector 4 respectively, and on the right side of upper ratchet 5 pawl teeth section and lower ratchet left side under the internal gear of pawl teeth section and connector 4 disengage, like this when pawl base 3 rotates counterclockwise, the internal gear dieback of upper ratchet 5 and lower ratchet 6 and connector 4, connector 4 is driven also and then to rotate counterclockwise, and when pawl base 3 rotates clockwise, upper ratchet 5 and lower ratchet 6 slightly turn round, make that pawl base 3 dallies and the internal gear of connector 4 is motionless, reciprocal swinging handle bar 1 can make connector 4 continue to rotate counterclockwise, and when needs connector 4 rotates clockwise, then only need to pinch stopper ring 13 and rotate poke rod 7 to another stable state, now go up the decorative pearl on top of an official cap 8 and the lower decorative pearl on top of an official cap 9 makes pawl teeth section and pawl teeth section under the left side of lower ratchet 6 on the right side of ratchet 5 contact the internal gear of connector 4 respectively, such pawl base 3 dallies counterclockwise, and drive connector 4 to rotate clockwise.
