Technical problem to be solved in the utility model is the valve mechanism that will provide a kind of high-tension switch cabinet.
In order to solve above technical problem, the utility model provides a kind of valve mechanism of high-tension switch cabinet, comprise valve plate and lower valve plate, described upper valve plate is connected with upper junction plate and lower connecting plate respectively by connecting rod with the both sides of lower valve plate, upper junction plate and lower connecting plate are respectively with upper, Lower shaft sleeve connects, upper junction plate is also connected with fixed head with lower connecting plate, fixed head is connected with bearing support, bearing support is connected by the madial wall of fixed head with high-voltage switch gear cabinet, a Compress Spring is provided with between upper junction plate and lower connecting plate, on, Lower shaft sleeve drives upper junction plate and lower connecting plate to move, make, lower valve plate is opened along guide rod or is closed.
Described lower valve plate two ends are connected with connecting rod by spring collar.
Top, described lower valve plate two ends is connected with support plate.
Be connected with support plate by elastic cylindrical pin bottom described upper valve plate two ends.
Described support plate is provided with the circular hole running through guide rod.
The upper end of described guide rod is provided with spacer pin, is the stopping means of upper valve plate.When guide rod passes the supporting bracket of lower valve plate, the spacer pin card of guide rod upper end on the supporting plate, prevents guide rod landing.
Operation principle of the present utility model: when circuit breaker shake into time, according to link transmission principle, when the frid of circuit breaker both sides touches upper and lower axle sleeve, upper and lower axle sleeve can drive upper and lower connecting plate respectively to upper and lower two rightabout vertically movements, and the upper and lower valve plate connected with upper and lower connecting plate is along with being separated in opposite directions.Along with the continuous propelling of circuit breaker, the upper and lower connecting plate connecting upper and lower axle sleeve drives upper and lower valve plate to slide up and down, until the Mume flower contact of circuit breaker contacts completely with the fixed contact in contact box, upper and lower valve plate is open at maximum position.When circuit breaker shakes out, upper and lower valve plate automatically draws in opposite directions along with the convergent force of Compress Spring together with upper and lower connecting plate, until cover contact box completely.
Superior effect of the present utility model is: structure is simple, easy to use, smooth, can not cause stucking phenomena during propelling.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Fig. 1 shows schematic front view of the present utility model; Fig. 2 shows the structural representation of upper and lower connecting plate of the present utility model.As depicted in figs. 1 and 2, the utility model provides a kind of valve mechanism of high-tension switch cabinet, comprise valve plate 20 and lower valve plate 14, the both sides of described upper valve plate 20 are connected with upper left connecting plate 11, upper right connecting plate 5 respectively by upper connecting rod 16, and the both sides of described lower valve plate 14 are connected with lower-left connecting plate 6, bottom right connecting plate 3 respectively by lower link 12.Upper left connecting plate 11 is connected with Upper shaft sleeve 10, Lower shaft sleeve 7 respectively with lower-left connecting plate 6, and upper right connecting plate 5 is also connected with Upper shaft sleeve 10, Lower shaft sleeve 7 respectively with bottom right connecting plate 3.Upper left connecting plate 11 is connected with left fixed head 8 with lower-left connecting plate 6, and upper right connecting plate 5 is connected with right fixed head 2 with bottom right connecting plate 3.Left fixed head 8 is connected with left bearing support 9, and right fixed head 2 is connected with right bearing support 1, and left bearing support 9 is connected with the madial wall of high-voltage switch gear cabinet with right fixed head 2 by left fixed head 8 with right bearing support 1.Between upper left connecting plate 11 and lower-left connecting plate 6, be provided with a Compress Spring 4, be also provided with a Compress Spring 4 between upper right connecting plate 5 and bottom right connecting plate 3, the compression stress by both sides Compress Spring makes upper and lower connecting plate move.The Upper shaft sleeve 10 of the left and right sides and Lower shaft sleeve 7 drive upper left connecting plate 11, upper right connecting plate 5 and lower-left connecting plate 6, bottom right connecting plate 3 moves, and make valve plate 20 and lower valve plate 14 open along guide rod 19 or close.
