Detailed description of the invention
Fig. 1 is in the structural schematic diagram under gate-dividing state in earthing switch for the utility model interlocking mechanism.
Fig. 2 is in the structural schematic diagram under "on" position in earthing switch for the utility model interlocking mechanism.
Fig. 3 is structural schematic diagram of the utility model interlocking mechanism under hatch door opening state.
Specific embodiment
The preferred embodiment that according to the present invention will be described in detail below with reference to the accompanying drawings.
Embodiment one
It please refers to Fig.1 to Fig.3, the utility model discloses the interlocking machine of a kind of combined electrical apparatus cabinet earthing switch and cabinet door
Structure, the interlocking mechanism include: ground connection handle hole baffle 1, ground connection interlocking ring 2, reset connecting plate 3, interlocking latch 4, resetting-mechanism 5,
Cable vault's hatch door pull rod 6, pull rod resetting-mechanism 7.
The ground connection handle hole baffle 1 is a kind of programed interlocking plate, must unlock this baffle before operational grounding switch；It is described
Ground connection interlocking ring 2 is the locking part for being latched or unlocking cable vault's hatch door.The reset connecting plate 3 is by fastener and resets machine
Structure is connected, and resetting connecting plate 3 is the locking part being driven by resetting-mechanism.
In the case where ground connection interlocking ring 2 is in blocking, the interlocking latch 4 is logical by bolt with the ground connection handle hole baffle 1
It crosses and is bolted and (other connection types can also be used), when ground connection handle hole baffle 1 is driven to first direction movement, interlocking
Pin 4 also moves.
In the case where being grounded chain ring 2 in unlocked state, the interlocking latch 4 is connect with resetting-mechanism 5, is driven by resetting-mechanism 5
It is mobile towards second direction；It is grounded chain ring 2 and forms interlock connection with cable vault's hatch door pull rod.
The 6 connecting cable room hatch door of cable vault's hatch door pull rod, can open or close with cable vault's hatch door and be moved up and down
Cable vault's hatch door pull rod 6 forms corresponding interlock connection with interlocking latch 4.
The 7 connecting cable room hatch door pull rod of pull rod resetting-mechanism, in the state that in cable vault, hatch door is opened, cable vault
Hatch door pull rod moves under the driving of pull rod resetting-mechanism 7, forms corresponding interlock connection with interlocking latch 4.
Locking principle: original state is grounded chain ring 2 and is in latch like as shown in Figure 1, earthing switch is in gate-dividing state
State, interlocking latch 4 blocks moving up for cable vault's hatch door pull rod 6 at this time, causes above to mention to open cable vault's hatch door.In order to protect
The safety of maintenance is demonstrate,proved, it is necessary to the splice grafting ground openable cable vault's hatch door in rear.Push ground connection handle hole baffle 1 aside to the left first,
In being inserted into hexagonal operation handle rotate clockwise 180 ° at this time ground connection interlocking ring 2 unlocked reset connecting plate 3 after rotating with it, it is multiple
Position connecting plate 3 is connect by fastener with interlocking latch 4 and under the action of resetting-mechanism 5 (reset dog chart) while being moved, therefore
Handle resets after extracting to move right under promotion of the connecting plate 3 by resetting-mechanism 5 (reset dog chart), at the same time interlocking latch 4 also to
It moves right, finally makes interlocking latch 4 that cable vault's hatch door pull rod 6 can not be stopped to move up (as shown in Figure 2) again, i.e., it at this time can be by above mentioning
Cable vault's hatch door opens this door, carries out cable vault's maintenance.
Cable vault's hatch door pull rod 6 moves up under the action of pull rod return spring 7 after when cable vault, hatch door is opened, and finally keeps off
4 left side of interlocking latch.Because operational grounding switch need to push ground connection handle hole baffle 1 aside to the left, however it is grounded handle hole baffle 1 and multiple
It is to link, and because the gear of cable vault's hatch door pull rod 6 is in interlocking at this time by structure design between position connecting plate 3 and interlocking latch 4
The left side of pin 4, therefore be grounded handle hole baffle 1 and also can not just move left, i.e., can not insertion operation handle operate (such as with tapping
Shown in Fig. 3), to ensure that safety of the people in maintenance.
In conclusion the utility model proposes combined electrical apparatus cabinet earthing switch and cabinet door interlocking mechanism, it can be ensured that set
It is standby in splice grafting when overhauled, guarantee the safety of personnel.Meanwhile the utility model uses the simple metal plate of structure and machining
Part is used cooperatively the use to replace profile and nylon withdrawal line, so as to shorten the production cycle, ensures the reliable of long-time service
Property.
Here the description and application of the utility model are illustrative, are not wishing to for the scope of the utility model being limited in
It states in embodiment.The deformation and change of embodiments disclosed herein be it is possible, for the ordinary skill people of those this fields
The replacement of embodiment and equivalent various parts are well known for member.It should be appreciated by the person skilled in the art that not taking off
In the case where spirit or essential characteristics from the utility model, the utility model can in other forms, structure, arrangement, ratio,
And it is realized with other components, material and component.It, can be to this in the case where not departing from the scope of the utility model and spirit
