Abstract
The utility model relates to a kind of ratchet overdrive clutch and applies its reclosing Aftercurrent protection circuit breaker.The utility model is characterized in that comprising the ratchet and pawl dish cooperatively interacted, and described pawl disk is connected with manual lever by fixture, and when manual lever rotates clockwise, pawl disk is meshed with ratchet, and pawl disk drives pawl wheel; When manual lever rotates counterclockwise, pawl disk and ratchet depart from, and do not drive pawl wheel.The utility model can effectively prevent user's misoperation from causing the wearing and tearing caused equipment, guarantees that equipment normally runs, extends the useful life of circuit breaker.
Description
One, technical field
The utility model relates to a kind of ratchet overdrive clutch and applies its reclosing Aftercurrent protection circuit breaker, and it is the architecture advances to existing reclosing Aftercurrent protection circuit breaker.Belong to low-voltage electrical apparatus manufacturing technology field.
Two, background technology
As illustrated in fig. 1 and 2, existing a kind of reclosing Aftercurrent protection circuit breaker, mainly comprise breaker body 14, motor 6, gear train, support 5, manual lever 7, outer ring 8, rotating disk 1, driving lever 2, connecting rod 10, spring 13, fixture 4, overcurrent and residual current protecting electric sub-member plate 11 etc., described gear train comprises gear wheel 12 and pinion 3, described gear wheel, rotating disk, outer ring is arranged on motor upper end successively, described pinion is arranged on relevant position on manual lever, described driving lever is arranged on the driving shaft of motor, described connecting rod one end is connected with the handle 9 of breaker body, the other end is connected with rotating disk.When electric sub-member plate controls motor counterclockwise to rotate, driving lever withstands on the tooth of outer ring, and make outer ring, rotating disk and then rotates together, thus drive the connecting rod rotation be arranged on rotating disk, driving handle divides, combined floodgate circuit breaker.When manual operation manual lever rotates in a clockwise direction, the pinion turned clockwise drives gear wheel, rotating disk, outer ring counterclockwise to rotate, outer ring tooth leaves driving lever motion, and same drivening rod and handle divide, combined floodgate circuit breaker, and not drive motor.But when manual operation manual lever is with when counterclockwise (oppositely) rotates, the pinion be rotated counterclockwise drives gear wheel, rotating disk, outer ring is rotated in a clockwise direction, outer ring tooth promotes driving lever makes motor driving shaft and then rotate.Because motor is with reducing gear, output torque is comparatively large, and manual hand manipulation must overcome output torque just can make motor driving shaft rotate.Imperative operation like this, makes the part such as driving lever, motor driving shaft bear larger external force, and multi-pass operation will produce part and damages and shorten its useful life, thus affect useful life and the maintenance cost of complete machine.In addition, larger operating physical force, also will reduce the user experience of user.
Three, summary of the invention
In view of above-mentioned Problems existing, the purpose of this utility model is to provide a kind of ratchet overdrive clutch structure rational in infrastructure, is applied to reclosing Aftercurrent protection circuit breaker.When user's manual operation is reverse, other component part is not had a negative impact, and guide user with correct direction operation, guarantee that equipment normally runs, increase the service life.
For achieving the above object, the utility model takes following measures:
A kind of ratchet overdrive clutch, it is characterized in that comprising the ratchet and pawl dish cooperatively interacted, described pawl disk is connected with manual lever by fixture, and when manual lever rotates clockwise, pawl disk is meshed with ratchet, and pawl disk drives pawl wheel; When manual lever rotates counterclockwise, pawl disk and ratchet depart from, and do not drive pawl wheel.
Described pawl disk is arranged on the top of ratchet, and the bottom of described ratchet arranges support spring.
Described ratchet comprises pinion feature and ratchet feature.
The helically face, mating surface local of described ratchet and pawl disk
A kind of reclosing Aftercurrent protection circuit breaker; it mainly comprises breaker body, motor, gear train, support, outer ring, rotating disk, driving lever, connecting rod, spring, overcurrent and residual current protecting electric sub-member plate, is provided with above-mentioned ratchet overdrive clutch in it.
During use, when manual lever rotates clockwise, because pawl disk is connected with manual lever by fixture, pawl disk is meshed with ratchet, and therefore, pawl disk drives pawl wheel, thus realizes transmission; When rotate counterclockwise by (oppositely) for manual lever, pawl disk and ratchet depart from, and do not drive pawl wheel, it is invalid to operate, other component part is not had a negative impact, in addition, after turning an angle, when pawl disk and ratchet enter into next mating part, due to the effect of spring, produce collision, sound, prompting user recognizes direction of operating mistake, thus guides user with correct direction operation.
The utility model can effectively prevent user's misoperation from causing the wearing and tearing caused equipment, guarantees that equipment normally runs, extends the useful life of circuit breaker.

Fig. 2 is the gear train dependency structure in existing circuit breaker
Fig. 3 is the schematic diagram of ratchet, pawl disk
Fig. 4 is the structural representation of the utility model embodiment.
Five, embodiment
As shown in Figures 3 and 4, the utility model discloses a kind of ratchet overdrive clutch, it comprises: ratchet 16, pawl disk 17, spring 15, fixture 18, manual lever 19.Wherein, described ratchet comprises pinion feature and ratchet feature; Described pawl disk is provided with a fixing hole, pawl disk and manual lever is fixed with fixture; Described spring fitting, under ratchet, provides the confining force that ratchet engages with pawl disk; Described ratchet and the mating part of pawl disk adopt helicoid.During use, when manual lever rotates clockwise, because pawl disk is connected with manual lever by fixture, pawl disk is meshed with ratchet, and therefore, pawl disk drives pawl wheel, thus realizes transmission; When rotate counterclockwise by (oppositely) for manual lever, pawl disk and ratchet depart from, and do not drive pawl wheel, it is invalid to operate, other component part is not had a negative impact, in addition, after turning an angle, when pawl disk and ratchet enter into next mating part, due to the effect of spring, produce collision, sound, prompting user recognizes direction of operating mistake, thus guides user with correct direction operation.
