Description
Technical field
The present invention relates to a kind of mechanism of low-voltage electrical apparatus, specifically a kind of action locking gear of isolating switch.
Background technology
Existing small-sized modularization isolating switch adopts the Direct Action Type double-breakpoint structure, the attonity lock function more.This isolating switch, handle is easy to generate misoperation, can bring potential safety hazard.
Summary of the invention
What the present invention will solve is the problem of existing isolating switch poor stability, aims to provide a kind of action locking gear, improves the fail safe that isolating switch uses.The technical scheme that addresses the above problem employing is: a kind of action locking gear of isolating switch, comprise knob, retainer and spring, described knob sleeve is contained on the described retainer, described retainer also is provided with a stopper arms, and the handle of described isolating switch is provided with to match to merge with described stopper arms and makes described isolating switch be locked in the boss of closure or off-state at least; Described spring one end is arranged on the described stopper arms, and the other end is arranged on the fixed part of isolating switch.
Action locking gear of the present invention, cooperatively interact by stopper arms on the retainer and the boss on the handle, and the tension force effect of spring, make handle be locked in closure and/or off-state, avoid misoperation thereby reach, improve the purpose of isolating switch fail safe.Simultaneously, thus by turning knob the retainer interlock is unlocked easily.
As a further improvement on the present invention, the boss on the described handle is provided with corresponding to first stop surface of closure state with corresponding to second stop surface of off-state.Can guarantee that like this handle can be locked respectively at two states of isolating switch closed and disconnected.
As further improving again of this invention, described second stop surface is a convex arc surface, is provided with the stop surface of the concave arc shape that described second stop surface matches on described stopper arms.Like this, can increase both faying faces, make locking more reliable and stable.The main part of described knob and retainer is cylindrical, and is arranged in the circular groove of isolating switch shell.Described knob is sleeved on the square column that is provided with on the described retainer by the square hole of offering on it.
Further improve as of the present invention, the upper surface of described stopper arms matches with first stop surface of described handle boss, and its end also is provided with an arc surface that matches with described handle rotating part outer circumference surface.Like this, no matter be when static or the process of action in, retainer all can cooperate well with handle.

Embodiment
With reference to accompanying drawing, isolating switch self has the actuating mechanism that shell 21, dividing plate 22, handle 26, " U " shape bar 27 and contact system 28 are formed, and action locking gear of the present invention comprises knob 25, retainer 24 and spring 23.The main part of described knob 25 and retainer 24 is cylindrical, and is arranged in the circular groove 42 of isolating switch shell 21.Described knob 25 is sleeved on the square column 38 that is provided with on the described retainer 24 by the square hole of offering on it 39, and turning knob 25 like this, and retainer 24 can interlock.Described retainer 24 also is provided with a stopper arms 36, the handle 26 of described isolating switch is provided with the boss 33 that matches with described stopper arms 36, and described boss 33 is provided with corresponding to first stop surface 34 of closure state with corresponding to second stop surface 35 of off-state.Described second stop surface 35 is a convex arc surface, is provided with the stop surface 37 of the concave arc shape of matching with described second stop surface 35 on described stopper arms 36.The upper surface 40 of described stopper arms 36 matches with first stop surface 34 of described handle boss, and the end of described stopper arms 36 also is provided with an arc surface 41 that matches with described handle rotating part outer circumference surface.
Described spring 23 1 ends be hooked on stopper arms 26 bottoms set circular hole 31 in, the other end be hooked on the dividing plate 22 be provided with circular hole 32 in, when knob 25 drives retainer 24 motions, drive retainer 24 after the spring 23 stretching energy storage and return back to latched position or unlocked position.
With reference to Fig. 1, Fig. 6, action locking gear is in released state, because the active force of spring 23, knob 25 and retainer 24 are fixed, and no external force effect knob 25 and retainer 24 will can not move.At this moment, at this moment, boss 33 and stopper arms 36 no any interference on the handle 26, actuating mechanism can drive the conversion that contact system 28 is finished closed and disconnected by handle 26 and U-shaped bar 27.
With reference to Fig. 2, action locking gear is locked in make position, because the active force of spring 23, knob 25 and retainer 24 are fixed, and no external force effect knob 25 and retainer 24 will can not move.At this moment, actuating mechanism is locked in make position, and the upper surface 40 of stopper arms blocks first stop surface 34 of handle boss, and driving handle 26 can't be finished contact system 28 from the conversion of make position to open position.At this moment, be rotated counterclockwise knob 25, retainer 24 also and then turns to the sidewall that stopper arms 36 touches shell 21, and under the effect of spring 23, retainer 24 is stabilized in this position, and stopper arms 36 is thrown off with boss 33, and handle is disengaged locking.
Rotate counterclockwise handle 26 and arrive the isolating switch open position, clockwise rotate knob 25 then, retainer 24 also and then turns to another sidewall that stopper arms 36 touches shell 21.As Fig. 3, shown in Figure 5, under the effect of spring 23, retainer 24 is stabilized in this position, and no external force effect knob 25 and retainer 24 will can not move.At this moment, actuating mechanism is locked in open position, and the concaved circular cambered surface 37 of stopper arms 36 is relative with second stop surface 35 of handle boss, and driving handle 26 can't be finished contact system 28 from the conversion of open position to make position.
What should be understood that is: the foregoing description is just to explanation of the present invention, rather than limitation of the present invention, and any innovation and creation that do not exceed in the connotation scope of the present invention all fall within protection scope of the present invention.
