Description
Technical field
The utility model belongs to breaker technical field, and in particular to a kind of sincere son of breaker spring operating mechanism.
Background technology
It is very extensive in field of power transmission, the application of breaker.Spring operation is the important component of breaker, existing
There is the breaker spring operating mechanism in technology to include on/off switch control device, the closing control device includes combined floodgate half
Axis, sincere sub- axis and sincere son, as shown in Figure 1, sincere attached bag includes the installation end at rear portion and anterior positive stop end in the prior art, it is described sincere
The installation end of son is sleeved on sincere sub- axis, and the sincere sub positive stop end end face is semicircle cambered surface, is provided with the floodgate semiaxis
With the sincere sub- matched pit in positive stop end end face, under energy storage state, sincere sub positive stop end lower face snaps onto floodgate semiaxis
On outer end face, during combined floodgate, floodgate semiaxis rotates clockwise, and pit and sincere sub limit in floodgate semiaxis are turned to when floodgate semiaxis
When position end lower face is in contact, sincere son also begins to be rotated clockwise under the action of torsional spring, i.e., sincere sub dropout process, sincere
Son achievees the purpose that combined floodgate after turning to certain angle, during dropout, exceedes it during sincere sub- rotation in order to prevent and rotates model
The problem of enclosing, causing integrated model not reset, the prior art limit sincere son using stop screw is installed on the cover board
Position, after sincere son turns to certain angle, sincere son be subject to stop screw because being stopped, so that stop operating, but due to spacing spiral shell
Nail rigidity is strong and crisp, and stop screw after sincere sub long-term collision with being easily broken off, and after stop screw fracture, sincere son is without limit
Position device it is spacing so that cause it is sincere it is sub rotate more than its slewing area, ultimately resulting in integrated model can not reset, it is necessary to
Arrange maintenance.
Utility model content
During the utility model is solves to thread off, after stop screw fracture, sincere son carries out spacing without limiting device
Cause to rotate more than its slewing area, so as to cause the technical problem that integrated model can not reset, there is provided a kind of breaker bullet
The sincere son of spring operating mechanism.
The technical solution adopted in the utility model is as follows：
A kind of sincere son of breaker spring operating mechanism, including the installation end at rear portion and anterior positive stop end, the installation
End cap is on sincere sub- axis, and the end face of the positive stop end is semicircle cambered surface, and the upper end end of the semicircle cambered surface is spacing equipped with one
Step.
The height of the limited step is 2~3mm.
The limited step is arranged at the upper end end 10mm away from semicircle cambered surface.
Torsional spring is arranged with the sincere sub- axis, one end of the torsional spring is fixed on sincere sub- axis, and the other end is fixed on partition plate
On.
The beneficial effects of the utility model：The utility model is simple in structure, by the semicircle cambered surface of sincere sub- positive stop end
One limited step is set, and during efficiently solving dropout, after installing stop screw fracture on the cover board, sincere son is without limit
Position device progress is spacing to be caused to rotate more than its slewing area, so as to cause the technical problem that integrated model can not reset, is strengthened
The stability of mechanism.

Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
As shown in Figure 2,3, 4, a kind of sincere son of breaker spring operating mechanism, including the installation end 11 at rear portion and front portion
Positive stop end 12, the installation end 11 are sleeved on sincere sub- axis 2, and the both ends of the sincere sub- axis 2 may be rotatably mounted at both sides respectively
On partition plate 5, torsional spring 4 is arranged with the sincere sub- axis 2, one end of the torsional spring 4 is fixed on sincere sub- axis 2, and the other end is fixed on
On partition plate 5, the end face of the anterior positive stop end 12 of the sincere son be semicircle cambered surface, the upper end end of the semicircle cambered surface equipped with one to
On limited step 13, the distance of lower end to the limited step 13 of the semicircle cambered surface can guarantee that after dropout that breaker is in and closes a floodgate
State.The height of the limited step 13 is arranged to 2~3mm, and the limited step 13 is arranged on away from semicircle cambered surface upper end end
At 10mm.The utility model in the semicircle cambered surface of sincere sub- positive stop end 12 by setting a limited step 13, during dropout,
After sincere son turns to certain angle under the action of torsional spring 4, the step in sincere sub- 12 semicircle cambered surface of positive stop end snaps onto combined floodgate
On semiaxis, so as to prevent sincere son from being rotated further, the limited step 13 plays good position-limiting action, enhances the steady of mechanism
It is qualitative.
While there has been shown and described that the embodiment of the utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from the principle of the utility model and spirit, repaiied
