Embodiment
A kind of cable vault door interlock, it is arranged on the cable vault, and comprises one first interlocking device and one second interlocking device.This cable vault comprises that a cabinet 100, connects the door body and an earthed switch operation axis 200 of cabinet, the first side of this body can slide up and down connection, relative longitudinal axis this cabinet right plate 110 that is rotationally connected, and offers a handle hole and on this cabinet and can rotate the shield 300 that whether hides handle hole to control.
This first interlocking device please refers to Fig. 1, comprises an interlocking bent plate 10, a linkage support 12, a cam 14, commutation connecting lever 16, a first connecting rod 18 and a blocking pin 20.10 fixedly connected bodies of this interlocking bent plate, and cabinet 100 slides up and down relatively.
This blocking pin 20 can connect cabinet 100 horizontally slidingly, and has an inner and outer end.Owing to slide, therefore can control the outer end of blocking pin 20 and whether stretch out outside the cabinet 100, if stretch out outside the cabinet 100 then can stop that interlocking bent plate 10 slides up and down, if do not stretch out then the bent plate 10 that allows to interlock slides up and down.Be provided with one second elastomer 22 between this blocking pin 20 and the cabinet 100, this second elastomer 22 can make blocking pin 20 be subjected to outside elastic force to reset.
This commutation connecting lever 16 is a V-arrangement, it has a middle part and is positioned at first end and second end of both sides, middle part, and this middle part is rotated and is arranged on cabinet 100, and this first end connects blocking pin 20 the inners, and this commutation connecting lever 16 rotates and can drive blocking pin 20 relative cabinet 100 horizontal slips.Connection between these commutation connecting lever 16 first ends and blocking pin 20 the inners is in the following way: these commutation connecting lever 16 first ends offer one and slide and wear groove, are installed with a pin on these blocking pin 20 the inners, and this pin slides, is rotatably connected on to slide and wears in the groove.
This linkage support 12 can slide up and down to be arranged on the cabinet 100, and it comprises a top board, a pole and one first elastomer.This pole top is installed in the top board bottom surface, and this first elastomer is arranged between pole and the cabinet 100 and makes linkage support 12 be subjected to making progress elastic force to reset.
This first connecting rod 18 be rotationally connected commutation second end of connecting lever 16 and the pole top of linkage support 12, so linkage support 12 slides up and down and can drive commutation connecting lever 16 and rotate.
These cam 14 coaxial being installed on the earthed switch operation axis 200, and the top board of these cam 14 side face contact linkage support 12, so this operation axis 200 rotates and can drive cam 14 and rotate, this cam 14 rotate and can drive linkage support 12 and slide up and down.
When this body can not promote (sliding up and down), door was known from experience and to be blocked and can't open by the block piece on four limits, so operating personnel need beat opening door body and just must first raise up door.When the earthed switch separating brake, stop and can't promote because the interlocking bent plate 8 on this body is extended blocking pin 20 outside cabinet 100 right plates 110, therefore this body can not be opened, guarantee only to disconnect at circuit breaker, under the situation of earthed switch ground connection, this body just can be opened, and operating personnel just can enter in the switch cubicle.When operating personnel's manual operation handle rotates earthed switch operation axis 200, this cam 14 is followed rotation, contact compressing linkage support 12 top boards are to lower slider, this linkage support 12 drives first connecting rod 18 again and moves down, driving commutation connecting lever 16 again rotates, drive blocking pin 20 again and draw back, this moment, Men Tike promoted, and can open.After the door body was closed, under first elastomer and the second elastomer effect, this mechanism is returned to can not open mode.
This second interlocking device please refers to Fig. 2,3,4, and it is arranged on the installing rack 120 of cabinet, and it comprises a block piece 24, a second connecting rod 26, an ears connecting lever 28, a rotating shaft 30, a trip lever 32 and a release bent plate 34.
This block piece 24 can be arranged on cabinet 100 horizontally slidingly, and has an inner and outer end.Owing to slide, therefore whether stretch out outside the cabinet 100 outer end that can control block piece 24, if stretch out outside the cabinet 100 then can contact shield 300 sides, can stop that shield 300 rotates, can guarantee that shield 300 hides handle hole, can guarantee that operating personnel can't insert operation tool by handle hole, can guarantee to disconnect earthed switch, if do not stretch out then allow shield 300 to rotate.
These block piece 24 the inners second connecting rod 26 1 ends that are rotationally connected, these second connecting rod 26 other ends ears connecting lever 28 1 ends that are rotationally connected, this ears connecting lever other end is installed in rotating shaft 30 tops, this rotating shaft 30 is rotated and is arranged on cabinet 100, and, these rotating shaft 30 bottoms connect trip lever 32 the inners, and this trip lever 32 can be arranged on cabinet 100 horizontally slidingly.This rotating shaft 30 connects trip lever 32, and the horizontal slip that makes this trip lever 32 can drive rotating shaft 30 rotations, this connection is in the following way: be installed with the connecting lever 36 that resets in this rotating shaft 30, offer a slip on the end of this connecting lever 36 that resets and wear groove, these trip lever 32 the inners are installed with a pin, and this pin slides, is rotatably connected on to slide and wears in the groove.
34 fixedly connected bodies of this release bent plate, and, this release bent plate 34 can contact trip lever 32 outer ends can make trip lever 32 horizontal slips.Being provided with one the 3rd elastomer, 38, the three elastomers 38 between this trip lever 32 and the cabinet 100 can make trip lever 32 be subjected to outside elastic force to reset.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
