Assembling be independent of each other, it is ensured that respective kinematic dexterity, also ensure to coordinate between failure reset button and mask is accurate
Degree.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：A kind of failure reset
Device, including pedestal, mask and executing agency, the mask are fixedly mounted on pedestal, and the executing agency is arranged on mask
Inside, the executing agency includes fault trip plate, mounting bracket, power transmission shaft and SR, and the fault trip plate passes through
Rotary shaft is arranged on pedestal, and fault trip plate can be rotated around rotary shaft, and the mounting bracket is fixedly mounted on pedestal, and
Mounting bracket is provided with the through hole being engaged with power transmission shaft, and the power transmission shaft is passed through in the through hole of mounting bracket, and is driven
Axle can make relative slip in through-holes, and the left end of the power transmission shaft is in contact with fault trip plate, and the SR is by button
Instruction unit and grab are integrally formed composition U-shape structure, and the button indicia left end of the SR is installed through face
On cover, the right-hand member of SR is in contact with power transmission shaft, and the button indicia of the SR is also socketed with back-moving spring, institute
The two ends of back-moving spring are stated respectively at acting on mask and SR, the face masks are additionally provided with to be engaged with grab
Limited block, distance that the limited block can be moved downward to grab carries out spacing.
Preferably, the button indicia of the SR is not located on the same line with power transmission shaft.
Preferably, the two ends of the power transmission shaft are set to hemispherical configuration.
Compared with prior art, usefulness of the present utility model is：The present apparatus makes SR be held with intelligent controller
Row mechanism separate, reduce the difficulty of assembling there is provided efficiency of assembling, reduce pedestal, intelligent controller executing agency, failure take off
Mismatch error between buckle, SR, mask, improves the reliability of motion, that is, improves the reliability of breaker, together
When also make outward appearance more perfect.
Brief description of the drawings：
The utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is normal operation of circuit breaker view.
Fig. 2 is fault state of circuit breaker schematic diagram.
Embodiment：
Below in conjunction with the accompanying drawings and the utility model is described in detail embodiment：
A kind of fault reset device as depicted in figs. 1 and 2, including pedestal 1, mask 6 and executing agency, the mask 6
It is fixedly mounted on pedestal 1, the executing agency is arranged on inside mask 6, the executing agency includes fault trip plate 3, peace
Support 4, power transmission shaft 5 and SR 7 are filled, the fault trip plate 3 is arranged on pedestal 1 by rotary shaft, fault trip plate 3
It can be rotated around rotary shaft, the mounting bracket 4 is fixedly mounted on pedestal 1 by modes such as screw, grabs, and mounting bracket
4 are provided with the through hole being engaged with power transmission shaft 5, and the power transmission shaft 5 is passed through in the through hole of mounting bracket 4, and power transmission shaft 5 can
Make relative slip in through-holes, the left end of the power transmission shaft 5 is in contact with fault trip plate 3, and the SR 7 is referred to by button
Show that portion and grab 101 are integrally formed composition U-shape structure, and the button indicia left end of the SR 7 is installed through
On mask 6, the right-hand member of SR 7 is in contact with power transmission shaft 5, and the button indicia of the SR 7 is also socketed with reset
Spring 8, the two ends of the back-moving spring 8 are additionally provided with respectively at acting on mask 6 and SR 7 inside the mask 6
The limited block 102 being engaged with grab 101, the distance that the limited block 102 can be moved downward to grab 101 carries out spacing.
When normal operation of circuit breaker, back-moving spring 8 promotes SR 7 to left movement, until the grab of SR 7
101 is spacing with the limited block 102 of mask 6, makes the button mark part of SR 7 concordant with mask 6, and SR 7, which is promoted, to be passed
Moving axis 5 is also to left movement, while making the distance between power transmission shaft 5 and fault trip plate 3 be contracted to the gap of very little；Work as breaker
When breaking down, fault trip plate 3 is rotated clockwise by center of rotation of rotary shaft, due to turning clockwise for fault trip plate 3
Dynamic, then fault trip plate 3 can promote power transmission shaft 5 to move right, and power transmission shaft 5 to motion then promotes SR 7 to move right,
The button mark portion of SR 7 is set to protrude mask 6, while compression reseting spring 8, makes the energy storage of back-moving spring 8, fault trip plate 3
Rotate clockwise after certain angle, fault trip plate 3 is pinned, then SR 7 can also be pushed into prominent mask 6 always.Carry
User's intelligent controller of waking up breaks down, and need to fix a breakdown.After failture evacuation, needing to promote counterclockwise manually to unlock.This
When, SR 7 protrudes mask 6, and Manual press SR 7 promotes SR 7 to the left, and SR 7 can promote biography
Moving axis 5 is to left movement, and power transmission shaft 5 then promotes restoring board 3 to rotate counterclockwise, and resets fault trip plate 3, i.e., intelligent controller is held
Row reset, breaker can continue normal work.
The button indicia of SR 7 is located on the same line with power transmission shaft 5, may be with other on mask 6
Location conflicts occur for part, therefore the button indicia of the SR 7 is not located on the same line with power transmission shaft 5, multiple
The U-shape structure bottom of position button 7 is contacted with power transmission shaft 5.
The two ends of the power transmission shaft 5 are set to hemispherical configuration, using this structure, have both been easy to power transmission shaft 5 through installation
The through hole of support 4, while the largest axis size of power transmission shaft 5 is wherein on heart axis, and then can ensure the two ends of power transmission shaft 5 by
Force is in central hub, therefore power transmission shaft 5 is not in the phenomenon of bite during actual motion.
It is emphasized that：It the above is only preferred embodiment of the present utility model, not the utility model appointed
What formal limitation, every any simple modification made according to technical spirit of the present utility model to above example, etc.
With change and modification, in the range of still falling within technical solutions of the utility model.
