Embodiment
Structure of the present utility model is described in detail below by way of specific embodiment, to be better understood from the utility model.
Embodiment 1
The interlock of cable chamber door and earthed switch in metal-closed switch cubicle, is arranged on earthed switch operation axis
Between 2 and cable chamber door 6, it is critical that interlock structure includes support 1, the plate washer being fixedly installed on operation axis 2
2-1 and the spacing plectrum 3 on support 1 of slip, cable chamber door 6 and support 1 reserve the action pane of plectrum 3, and the plectrum 3 is borrowed
The self-locking mechanism helped with the switch gearing of cable chamber door 6 has lock-out state and sliding mode, is formed and closes cable chamber door 6, plectrum 3
Slidably, operation axis 2 can freely operate and during 2 ungrounded state of operation axis baffle plate 2-1 to stop that cable chamber door 6 is opened mutual
Lock construction.
The interlock of cable chamber door and earthed switch in metal-closed switch cubicle, is arranged on earthed switch operation axis
Between 2 and cable chamber door 6, interlock structure includes support 1, plate washer 2-1 and plectrum 3, and support 1 is cabinet type, box or frame
Posture, cable chamber door 6 and support 1 are reserved with the action pane of plectrum 3, and plate washer 2-1 is fixedly installed on the side of operation axis 2,
When earthed switch is in ungrounded position, plate washer 2-1 is located at the front of cable chamber door 6 so that cable chamber door 6 can not be opened；Plectrum
3 slips are spacing on support 1, and linked by the self-locking mechanism linked with cable chamber door switch motion with cable chamber door 6, formed
When cable chamber door is closed, self-locking structure unblock, plectrum 3 is in slidably state, slide plectrum 3 can expose operation axis 2 from
And operational grounding is switched；Earthed switch is rotated to when being grounded position, cable chamber door 6 can be opened, then self-locking knot after cable chamber door 6 is opened
The position for locking plectrum 3 is made its akinesia by structure, and plectrum 3 blocks operation axis 2, it is impossible to which operational grounding is switched again.
The self-locking mechanism includes being opened in special-shaped chute 3-2 on plectrum 3, the sliding block 4 of vertical plectrum 3 and limited respectively
Back-moving spring 5 of the position between sliding block 4 and support 1 between stage clip 5, plectrum 3 and support 1, sliding block 4 has body and small external diameter
Head end 4-1, chute 3-2 have the limiting section 3-2-1 matched with the body external diameter of sliding block 4 and the slip matched with head end 4-1 external diameters
Body is locked in chute 3-2 limiting section 3-2-1 by portion 3-2-2, the sliding block 4 by stage clip 5, and when cable chamber door 6 is closed
Depress sliding block 4 and be embedded in sliding part 3-2-2 to head end 4-1, form the slip of plectrum 3.
Self-locking mechanism realizes self-locking and unblock by sliding block 4, abnormity chute 3-2 and stage clip 5, and special-shaped chute 3-2 is opened in
On plectrum 3, sliding block 4 is arranged on support 1 and vertical plectrum 3, and the spacing stage clip 5 that is provided with is used to control between sliding block 4 and support 1
The depth that sliding block 4 is penetrated in chute 3-2, back-moving spring 7 between plectrum 3 and support 1 be used to controlling the position of plectrum 3 so as to
It is to block or expose to operation axis 2 to control plectrum 3.It is sliding more it is essential that sliding block 4 has the head end 4-1 of body and small external diameter
Groove 3-2 has the limiting section 3-2-1 matched with the body external diameter of sliding block 4 the and sliding part 3-2-2 matched with head end 4-1 external diameters, electricity
Under the door open mode of cable room, the top pressure sliding block 4 of stage clip 5 makes its body part（Large outer-diametric portion）It is locked in chute 3-2 limiting section
3-2-1, now, sliding block 4 and chute 3-2 are in the lock state, plectrum 3 is in the presence of back-moving spring 7 without relative slip
Operation axis 2 is blocked, earthed switch is inoperable；When cable chamber door 6 is closed, pressure sliding block 4 to head end 4-1 is embedded in and slided
Portion 3-2-2, operation axis 2 can be exposed by stirring plectrum 3, so that operational grounding is switched, and rotate earthed switch operation axis 2 to connecing
During status, baffle plate 2 is then unobstructed to cable chamber door 6, and cable chamber door can be opened.
To ensure the balance and stability of plectrum 3, the sliding block 4 of above-mentioned cooperation can be bar shaped with special-shaped chute 3-2, form self-locking
While structure, guide effect is also acted as, control plectrum 3 is moved along special-shaped chute 3-2 directions, it is to avoid rotate etc.；To ensure solution
Lock and the flexibility of lock-out state conversion, the body and head end 4-1 of the sliding block 4 are cylinder, and head end 4-1 diameters are less than body
, the chute 3-2 has circle limiting section 3-2-1 and rectangular slide portion 3-2-2, and the sliding part 3-2-2 width is less than limit
Position portion 3-2-1 diameters, for cylindrical slider 4, also open up the locating slot 3-3 parallel to chute 3-2 on the plectrum 3, positioning
Set screw nut is installed, two parallel slot structures of locating slot 3-3 and chute 3-2 are spacing by plectrum 3, it is ensured that plectrum 3 in groove 3-3
Only there is the free degree moved along chute 3-2 directions.
For the Energy and comfort during use, the chute 3-2 is vertically to being opened on plectrum 3, and frame 1 is provided with postnotum
1-1, stage clip 5 is limited between sliding block 4 and postnotum 1-1, and vertical back-moving spring is provided between the plectrum 3 and support 1
7, such as frame 1 can set bottom plate 1-2, and back-moving spring 7 is spacing between the lower surface of plectrum 3 and bottom plate 1-2, when so operating, cable
Under 6 closed modes of door of room, vertically to bringing pressure to bear on plectrum 3, you can expose operation axis 2 can operational grounding switch to ground connection
Position, the indexing of baffle plate 2, cable chamber door 6 can be opened.
More stable during to move plectrum 3, the lower end of plectrum 3 is provided with horizonal base plate 3-4, and back-moving spring 7 is limited in water
Between flat underside 3-4 and support bottom plate 1-2.
The plectrum 3 passes the action pane of support 1 and cable chamber door 6 provided with handle 3-1, is easy to operation.
The utility model is when specifically used, when needing to safeguard or overhaul under the closed mode of cable chamber door 6, the head of sliding block 4
Hold in 4-1 insertion chutes 3-2, bring pressure to bear on plectrum 3, plectrum 3 can be moved up and down along chute 3-2 sliding part 3-2-2
Expose operation axis 2 so as to which operational grounding is switched, rotate earthed switch to when being grounded position, the indexing of baffle plate 2, cable chamber door 6 can be beaten
Open, open after cable chamber door 6, the body part insertion chute 3-2 of sliding block 4 limiting section 3-2-1, plectrum 3 blocks operation axis
2, now operational grounding switch is still in ground connection position and can not operate again, it is seen that equipment and the safety of operating personnel are had
Effect ensures.
