Abstract
The utility model discloses a sliding plate transmission device for a universal circuit breaker, and aims to redesign a small sliding plate, a big sliding plate, a pulley, a clipping plate, a lock catch, a shaft, a spring and a buckle piece arranged in a traditional sliding plate transmission device for a low voltage universal circuit breaker. After being redesigned, the transmission device is composed of a left sliding plate and a right sliding plate which are single sliding plate structures, and a main body positioning device. A main body loading bearing beam is arranged at the upper waist part of the sliding plate, and is a convex structure; the main body positioning device and the main body carrier bar are arranged in a T shape; and a limiting groove is arranged at the end part of the sliding plate. Without a complicated self-locking device, the utility model not only better solves the phenomenon of an excessively large gap created by accumulated error and fitting allowance due to the assembly of a plurality of parts, but also avoids the transmission malposition caused by the friction force of the self-locking device, thereby effectively ensuring that the sliding plate transmission device can reliably drive the circuit breaker body to advance and retreat in the drawer base of the circuit breaker.
Description
Technical field:
The utility model relates to a kind of universal low-voltage circuit breaker slide plate drive mechanism, belongs to the manufacturing technology neck of low-voltage electrical apparatus
The territory
Background technology:
The slide plate transmission device of drawer type omnipotent breaker is an important drive disk assembly of omnipotent breaker, and it is secure support and the important assurance of safe transmission that guarantees the main body switch.Industry mesolow omnipotent breaker slide plate transmission device is made up of left and right two slide plates that are made of small slide plate 1 and big slide plate 2 two parts shown in figure (1) usually at present.On big slide plate 2, be provided with spacing draw-in groove a and two slip elongated slot b, c, spacing draw-in groove a is used for the spacing of transmission device.On small slide plate 1, be provided with the positioner d of pulley 3 and clamp 4, snap close 5, axle 6, spring 7, cramp 8 and breaker body.Self-locking device is used for the interlocking of small slide plate 1 and big slide plate 2.Small slide plate 1 is installed in by pulley 3 and clamp 4 in chute b, the c of big slide plate 2, realizes the interlock of big small slide plate by the self-locking device of small slide plate 1, thereby the breaker body of realizing being installed among the positioner d of small slide plate 1 moves back and forth.This constructional device part is many, and complex structure, consumptive material are big; Because many part assemblings exist accumulated error and build-up tolerance, cause actuator movement not steady, stuck and phenomenon excesssive gap often takes place.Even because the frictional force effect of self-locking device, the reliably self-locking of large and small slide plate causes the transmission dislocation, thereby has brought potential safety hazard to electrical equipment.
Summary of the invention:
In view of the problem of above-mentioned existence, the purpose of this utility model provided a kind of simple in structure, part is few, the slide plate transmission device of easily manufactured, the safe and reliable omnipotent breaker of transmission.
For achieving the above object, the utility model has been taked following technical scheme:
The slide plate transmission device of a kind of omnipotent breaker described in the utility model, be that the small slide plate 1 in traditional low pressure all-purpose circuit breaker slide plate transmission, big slide plate 2, pulley 3, clamp 4, snap close 5, axle 6, spring 7, cramp 8 are redesigned, and it is combined into a part, constitute a single skateboard; Slide plate transmission device by the omnipotent breaker after the above-mentioned design is made of left and right two slide plate and the body positioners that are single skateboard; Waist on slide plate is provided with a body carrier bar, and the body carrier bar is presented convex structure; Body positioner and body carrier bar are T-shaped to be arranged, and spacing draw-in groove is arranged at the end of slide plate.
Through the utility model after the above-mentioned design, simple in structure, easy to make; Owing to omitted complicated self-locking device, not only solved the generation of the phenomenons such as excesssive gap that the accumulated error that produces owing to the assembling of many parts and build-up tolerance form well, also avoided the frictional force effect of self-locking device simultaneously and caused the transmission dislocation, thereby guaranteed that effectively the slide plate transmission device can drive the turnover of breaker body in circuit breaker drawer base reliably.

Embodiment
The slide plate transmission device of a kind of omnipotent breaker described in the utility model is made of left and right two slide plate 9 and the body positioner d that are single skateboard; Waist on slide plate 9 is provided with a body carrier bar 10, and body carrier bar 10 is presented convex structure; Body positioner d and body carrier bar 10 are T-shaped to be arranged, and body carrier bar 10 is used for the carrying of breaker body, and body positioner d is used for the location of breaker body with fixing; Spacing draw-in groove a is arranged at the end of slide plate 9, is used for slide plate 9 the spacing of position that move back and forth.
During use, breaker body is installed on the body carrier bar 10 by left and right two slide plates 9 that are single skateboard, and by the body positioner d location that is fixed; After the installing and locating, 11 the slide plate transmission device pushed in the circuit breaker drawer base by shaking hands, and spacing by spacing draw-in groove a, pull to prevent it.
