Abstract
The utility model relates to a spring pull rod aligning pad of a circuit breaker spring mechanism. The spring pull rod aligning pad comprises a spring mounting cylinder, a spring, a spring pressure disc and a pull rod, wherein the spring is connected to the spring pressure disc, the pull rod drives the spring pressure disc to realize energy storage of the spring, and the pull rod is positioned at the middle part of the spring mounting cylinder and passes through the spring pressure disc. The spring pull rod aligning pad is characterized that a pressing plate is connected to the lower side of the spring pressure disc, the middle part of the pressing plate is provided with a spherical cavity, the aligning pad is fixedly connected into the spherical cavity and the pull rod passes through the aligning pad.
Description
One, technical field
The utility model relates to a kind of parts of spring mechanism of circuit breaker, is specially a kind of spring pull bar center-adjusting pad of spring mechanism of circuit breaker.
Two, background technology
What the high pressure sulfur hexafluoride breaker adapted was maximum is spring operating mechanism, the divide-shut brake spring is the energy storage of spring mechanism and the parts of Chu Li, the energy storage of divide-shut brake spring drives platen by pull bar and realizes that Compress Spring comes energy storage, the pull bar of spring is not simple linear running, but the stack of rectilinear motion and circular motion, be the swing of horizontal or vertical direction, such as oscillating quantity platen is swung, cause spring stress inequality and platen and divide-shut brake spring fitting cylinder to rub, this can affect the branch wire time of mechanism and the stability of speed, and mechanism reliability is descended.
Three, summary of the invention
In order to overcome the above problems, the utility model provides a kind of spring pull bar center-adjusting pad that can guarantee that spring stress is even, avoid the spring mechanism of circuit breaker of frictional impact between spring pressure plate and the mounting cylinder.
The technical scheme that the utility model is taked is: a kind of spring pull bar center-adjusting pad of spring mechanism of circuit breaker, comprise spring fitting cylinder, spring, spring pressure plate, pull bar, described spring is connected on the spring pressure plate, thereby drive the energy storage that spring pressure plate is realized spring by pull bar, pull bar is positioned at the middle part of spring fitting cylinder, and pass spring pressure plate, it is characterized in that: described spring pressure plate below is connected with pressing plate, described pressing plate middle part is provided with spherical cavity, be fixedly connected with center-adjusting pad in the described spherical cavity, described pull bar passes center-adjusting pad.
The utility model has also designed described center-adjusting pad and has been connected with rod slide.
The bottom that the utility model has also designed described connecting rod is fixed with clamp nut.
The utility model has also designed described center-adjusting pad for conical.
The course of work of the present utility model is: spring pressure plate described in the utility model below is connected with pressing plate, described pressing plate middle part is provided with spherical cavity, described spherical cavity cooperates with center-adjusting pad, and center-adjusting pad can swing along with the spring pull bar, and pressing plate keeps and the spring perpendicular direction of exerting oneself.
The beneficial effects of the utility model are: the utility model spring mechanism of circuit breaker spring pull bar center-adjusting pad can solve the pull bar swing to the impact of mechanism characteristics, guarantees that spring stress is even, avoids frictional impact between spring pressure plate and the mounting cylinder.
Four, description of drawings
Fig. 1 is the spring pull bar center-adjusting pad structural representation of a kind of spring mechanism of circuit breaker of the utility model.
Five, embodiment
A kind of spring pull bar center-adjusting pad of spring mechanism of circuit breaker, comprise spring fitting cylinder 1, spring 2, spring pressure plate 3, pull bar 4, described spring 2 is connected on the spring pressure plate 3, thereby drive the energy storage that spring pressure plate 3 is realized spring 2 by pull bar 4, pull bar 4 is positioned at the middle part of spring fitting cylinder 1, and pass spring pressure plate 3, it is characterized in that: described spring pressure plate 3 belows are connected with pressing plate 5, described pressing plate 5 middle parts are provided with spherical cavity, be fixedly connected with center-adjusting pad 6 in the described spherical cavity, described pull bar 4 passes center-adjusting pad 6.
The utility model has also designed described center-adjusting pad 6 and has been slidingly connected with connecting rod 4.
The bottom that the utility model has also designed described connecting rod 4 is fixed with clamp nut 7.
The utility model has also designed described center-adjusting pad 6 for conical.
The course of work of the present utility model is: spring pressure plate described in the utility model 3 belows are connected with pressing plate 5, described pressing plate 5 middle parts are provided with spherical cavity, described spherical cavity cooperates with center-adjusting pad 6, and center-adjusting pad 6 can swing along with pull bar 4, and pressing plate keeps and spring 2 perpendicular direction of exerting oneself.
The beneficial effects of the utility model are: the utility model spring mechanism of circuit breaker spring pull bar center-adjusting pad can solve the pull bar swing to the impact of mechanism characteristics, guarantees that spring stress is even, avoids frictional impact between spring pressure plate and the mounting cylinder.
