Detailed description of the invention
Below in conjunction with the accompanying drawings, preferably embodiment of the present utility model is described in further detail:
In conjunction with Fig. 1 to 5, a kind of mechanical interlocks of ring main unit, including the cable vault 2 below operating room 1 and operating room 1, operating room 1 is outside is provided with support 3, push rod 4 vertically it is interspersed with on this support 3, it is horizontally disposed with L-type catch 6 on this push rod 4, between mount point and the support 3 of described catch 6, has spring 10；The lower end of described push rod 4 connects clamp 5, and the lower end of this clamp 5 is inserted in described cable vault 2；There is draw-in groove 11 described clamp 5 lower end, is provided with keeper 12 inside the cabinet door 9 of described cable vault 2, and this keeper 12 and described draw-in groove 11 are correspondingly arranged；Described operating room 1 is outside is also equipped with cam 8.
In conjunction with Fig. 2, described spring 10 is set on described push rod 4.When push rod is pressed for 4 times, spring 10 shrinks, and when spring 10 discharges pressure, promotes push rod 4 to rise.Spring 10 only can move along push rod 4 when shrinking and rebound, and position will not be occurred to offset.
In conjunction with Fig. 1 and Fig. 6, keeper 12 is vertical with cabinet door 9 inwall, and keeper 12 front end has prong, draw-in groove 11 to be positioned at the both sides of clamp 5.
In conjunction with Fig. 3, it is outside that cam 8 is arranged on operating room 1 by operation axle 7.
In conjunction with Fig. 4 and Fig. 5, being connected by bolt between support 3 and push rod 4, push rod 4 and clamp 5 are connected by bolt.It is conveniently replaceable push rod 4 and clamp 5.
Fig. 1 and Fig. 6, the left and right sides of cabinet door 9 inwall mentions 13, and there is jack 14 the doorframe both sides of cable vault 2, described in mention 13 and jack 14 be correspondingly arranged, it is necessary to cabinet door 9 is improved and could be taken out, and therefore cabinet door 9 is installed more firm.Use safer.
In conjunction with Fig. 4 to 6, lower pressure push rod 4, push rod 4 drives clamp 5 to move downward, and rotates cam 8, and the first end of catch 6 is pushed down in cam 8 front end, and now, ring main unit is in ground connection point state.Refilling Over-The-Counter door 9, during the prong of keeper 12 front end is stuck in the draw-in groove 11 of clamp 5 lower end inside cabinet door 9, fixed by clamp 5, push rod 4 will not rise.Prevent from unearthed opening cabinet door 9.
In conjunction with Fig. 4 to 6, rotating cam 8, cam 8 leaves the first end of catch 6, and now, ring main unit is in ground state.After opening cabinet door 9, the draw-in groove 11 of clamp 5 lower end departs from keeper 12, under the elastic force effect of spring 10, push rod 4 rises, and push rod 4 drives catch 6 to rise, after catch 6 rises, operation axle 7 is blocked by the second end of catch 6, it is impossible to rotate cam 8, prevents being not turned off cabinet door 9 and carries out joint point operation.
Push rod 4 slides up and down in the pilot hole of support 3, will not move in the horizontal direction.
First end of described catch 6 and the second end are vertical in the horizontal direction, and the first end of catch 6 and the horizontal plane at the second end place are vertical with push rod 4.
This utility model is simple and reliable for structure, prevents switch cubicle maloperation, reduces security incident.
Above content is to combine concrete preferred implementation further detailed description of the utility model, it is impossible to assert that of the present utility model being embodied as is confined to these explanations.For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, it is also possible to make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
