Abstract
The utility model relates to a locking mechanism, in particular to a locking mechanism of a switch cabinet grounding switch at the door-opening state. The locking mechanism comprises a panel of a switch cabinet; the grounding switch arranged in the panel; an interlocking board slidably arranged on the panel; a connection rod hinged on the interlocking board; an interlocking regulation crank hinged on the other end of the connection rod, wherein the interlocking regulation crank is fixed on an interlocking regulation crank shaft; the regulation crank shaft is rotatably arranged on the switch cabinet and in parallel to the rotation shaft of the cabinet door; a door-stop regulation crank is also fixed on the regulation crank shaft; the free end of the door-stop regulation crank is slidablyarranged on a long groove on the cabinet door; together with the opening and closing of the cabinet door, the interlocking board is driven to block or expose the grounding switch. When the cabinet door is open, the grounding switch is blocked by the interlocking board, so that the ground switch cannot be operated, and is prevented from being turned on by misoperation, and a torsional spring on the regulation crank shaft can keep the free opening state of the cabinet door.
Description
Technical field
The utility model relates to a kind of locking mechanism, relates in particular to a kind of switch cabinet grounding switch locking mechanism that opens the door.
Background technology
Switch cubicle runs into that inner body damages or during the situation such as circuit for generating fault, need to open the Xiamen of switch cubicle inside switch cabinet is keeped in repair, because switch cubicle is high-tension apparatus, if keeped in repair under charged state, once meet accident, its consequence is by hardly imaginable.Therefore, just need to when opening the door maintenance, earthed switch be closed a floodgate, prevent from getting an electric shock.So how to guarantee that earthed switch is a technical barrier in "on" position when the cabinet door is opened.
The utility model content
The utility model provides a kind of switch cabinet grounding switch locking mechanism that opens the door, and can guarantee that earthed switch is in "on" position when the cabinet door is opened.In order to realize the foregoing invention purpose, the utility model has adopted following technological means:
A kind of switch cabinet grounding switch locking mechanism that opens the door, comprise the panel of switch cubicle; Described panel is with the interior earthed switch that is provided with; Slide interlock plate is set on described panel; Articulated linkage on described interlock plate; The hinged chain connecting lever of the other end of described connecting rod; Chain connecting lever is fixedly installed on the connecting lever axle; Described connecting lever axle rotate be arranged on switch cubicle and with the shaft parallel of cabinet door; Also be fixedly installed gear door connecting lever on described connecting lever axle; The free end of described gear door connecting lever is slidably arranged in the elongated slot on the cabinet door; Along with the switching of cabinet door, drive interlock plate and block or expose earthed switch.
Offer switch hole on described panel; Offer the interlocking hole on described interlock plate; When the cabinet door is opened, interlocking hole and switch hole are overlapping;
On described connecting lever axle, torsion spring is set.
The beneficial effects of the utility model are: when the cabinet door is opened, interlock plate covers up earthed switch, thereby can not the operational grounding switch, prevents that misoperation from opening earthed switch; Torsion spring on the connecting lever axle can keep the free open mode of cabinet door.
The accompanying drawing explanation
Fig. 1 is the open the door structural representation of locking mechanism of a kind of switch cabinet grounding switch of the utility model;
The upward view that Fig. 2 is Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the open the door preferred implementation of locking mechanism of a kind of switch cabinet grounding switch of the utility model is made to detailed description:
As depicted in figs. 1 and 2, this switch cabinet grounding switch locking mechanism that opens the door, comprise the panel 1 of switch cubicle, and panel 1 is with the interior earthed switch 2 that is provided with, and in order to the earthing of console switch, closes a floodgate or separating brake.On panel 1 horizontal slip interlock plate 3 is set, offer interlocking hole 31 on interlock plate 3, switch hole 11 is set, in order to from the interior operational grounding switch 2 of switch hole 11 on panel 1.Along with horizontally slipping of interlock plate 3, interlocking hole 31 is can be with switch hole 11 overlapping or stagger.
On the bottom surface of interlock plate 3, articulated linkage 4, the hinged chain connecting lever 6 of the other end of connecting rod 4, and chain connecting lever 6 is fixedly installed on connecting lever axle 5.Connecting lever axle 5 rotate be arranged on switch cubicle and with the rotating shaft of cabinet door 10 all for vertically towards.
Also be fixedly installed gear door connecting lever 7 on connecting lever axle 5, the free end of described gear door connecting lever 7 is slidably arranged in the elongated slot 9 on cabinet door 10, and elongated slot 9 is opened on elongated slot plate 8, and elongated slot plate 8 is fixedly installed on the inboard of cabinet door 10.Along with the switching of cabinet door 10, drive interlock plate 3 and block or expose earthed switch 2.
Torsion spring 51 is set, in order to keep the free open mode of cabinet door 10 on connecting lever axle 5.
When using, when cabinet door 10 is opened, elongated slot 9 drives gear door connecting lever 7 to clockwise rotate, and then the chain connecting rod 4 that pulls moves to left, thereby making interlocking hole 31 on interlock plate 3 move to left staggers with switch hole 11, be that interlock plate 3 shelters from switch hole 11, making can not operational grounding switch 2, has prevented misoperation separating brake earthed switch 2.Otherwise, when cabinet door 10 is closed, elongated slot 9 drives gear door connecting levers 7 to rotate counterclockwise, and then chain promotion connecting rod 4 moves to right, thereby it is overlapping with switch hole 11 to make interlocking hole 31 on interlock plate 3 move to right, now can operational grounding switch 2.
