Description
Technical field
The utility model relates to the switch cubicle technical field, particularly a kind of withdraw-type switch cabinet valve structure.
Background technology
In withdraw-type switch cabinet, when the staff overhauls, when extraction can be removed parts, valve structure should guarantee closure, and high pressure and low pressure are kept apart, and guaranteed maintainer's safety; Otherwise when maintenance finishes, in the time of can removing parts and insert switch cubicle again, valve structure should guarantee to open fully and remain on reliably open position, to guarantee that switch cubicle normally moves.Traditional valve structure much adopts the guide rod guiding to drive valve and moves up and down, and adopts positive the installation, and it is very big to take up room, and might have influence on primary conductive loop Insulation Problems over the ground.
The utility model content
The purpose of the utility model is to provide a kind of valve structure of withdraw-type switch cabinet, to solve the problems of the technologies described above.
To achieve these goals, the utility model adopts following technical scheme:
A kind of valve structure of withdraw-type switch cabinet comprises firm banking, reduction torsion spring, last connecting lever, following connecting lever, goes up transmission connecting plate, underdrive connecting plate, left guide plate, right guide plate, goes up valve panel and following valve panel; Left side guide plate, right guide plate are installed on respectively on the switch cabinet body biside plate; Last valve panel is equipped with guide finger with following valve panel two ends, and guide finger is installed on respectively in the guide groove corresponding on left guide plate and the right guide plate; Firm banking is fixed on the switch cabinet body, and reduction torsion spring, last connecting lever, following connecting lever are installed on the base; Last connecting lever, last transmission connecting plate, last valve panel connect successively; Following connecting lever, underdrive connecting plate, following valve panel connect successively.
Be equipped with mutual disconnected upper rail and lower guide channel on left side guide plate and the right guide plate; The guide finger at last valve panel two ends is installed on respectively in the upper rail of left guide plate and right guide plate; The guide finger at following valve panel two ends is installed on respectively in the lower guide channel of left guide plate and right guide plate.
During the valve structure door opening state, the energy storage of following connecting lever compacting reduction torsion spring.
Firm banking is provided with a rotating shaft, and reduction torsion spring, following connecting lever and last connecting lever all are installed in the said rotating shaft.
With respect to prior art, the utlity model has following advantage: the valve structure of a kind of withdraw-type switch cabinet of the utility model, cancel traditional guide rod structure; Replacement is slided in the lower guide channel on the guide plate of the left and right sides with pivot pin, adopts the side to install, and has strengthened primary circuit distance over the ground; And the switching flexibility and reliability, the correlated parts processing technology is simple, when simplifying drive system, has improved structural strength; It is little to take up room, and is particularly useful for relevant miniaturization product.Guide plate is installed on the side cabinet, widens the air distance in transmission connecting plate and primary conductive loop as far as possible, increases insulating reliability.Whole valve structure is comparatively simple, and being slidingly matched between the high life of torsion spring and guide finger and the guide groove all guaranteed the high reliability that this valve structure opens and closes simultaneously.
Description of drawings
Fig. 1 is a valve closed condition sketch map;
Fig. 2 is the partial enlarged drawing of A portion among Fig. 1;
Fig. 3 is a valve open mode sketch map;
Fig. 4 is the partial enlarged drawing of B portion among Fig. 3.
Embodiment
Specify the technical scheme of the utility model below in conjunction with accompanying drawing.
See also Fig. 1 to shown in Figure 4, the valve structure of a kind of withdraw-type switch cabinet of the utility model comprises firm banking 1, reduction torsion spring 2, connecting lever 3, connecting lever 4, transmission connecting plate 5, transmission connecting plate 6, guide plate 8, goes up valve panel 9 and following valve panel 19.
Base 1 fixes with switch cabinet body, and connecting lever 3, connecting lever 4 are installed on the base 1, can rotate around base 1 rotating shaft; Rely on transmission connecting plate 5, transmission connecting plate 6 to be connected between connecting lever 3, connecting lever 4 and the valve, last valve panel 9, time valve panel 19 two ends are equipped with guide finger 7, and guide finger 7 can slide up and down in the guide groove of guide plate 8,10 centres.Guide plate 8,10 is installed on the switch cabinet body side plate, widens the air distance in transmission connecting plate 5, transmission connecting plate 6 and primary conductive loop as far as possible, increases insulating reliability.Whole valve structure is comparatively simple, and being slidingly matched between the high life of torsion spring 2 and guide finger 7 and the guide groove all guaranteed the high reliability that this valve structure opens and closes simultaneously.
It is inner that the withdraw-type parts insert switch cubicle, presses connecting lever 3, connecting lever 4; Wherein connecting lever 3 rotates along clockwise direction, and 2 energy storage of compacting reduction torsion spring drive transmission connecting plate 5 simultaneously and move downward, and following valve plate 19 is followed connecting plate 5 downward rectilinear motions under the constraint of guide finger 7 and guide plate guide groove; Simultaneously, connecting lever 4 drives transmission connecting plate 6 and moves upward along counterclockwise rotating, and last valve plate 9 also under the constraint of guide finger 7 and guide plate guide groove, is followed upwards rectilinear motion of transmission connecting plate 6, and then opened valve, guarantees the smooth insertion of withdraw-type parts.
When the maintainer outwards extracts the withdraw-type parts out; Connecting lever 3, connecting lever 4 have lost the compacting constraint in the outside; Wherein connecting lever 3 counterclockwise rotates in the effect lower edge of reduction torsion spring 2; Drive connecting plate 5 simultaneously and move upward, following valve plate 19 also under the constraint of guide finger 7 and guide plate guide groove, is followed upwards rectilinear motion of connecting plate 5; Simultaneously, connecting lever 4 rotates under the effect of last valve plate 9 gravity along clockwise direction, drives connecting plate 6 and moves downward; Last valve plate 9 is also under the constraint of guide finger 7 and guide plate guide groove; Follow connecting plate 6 downward rectilinear motions, after the withdraw-type parts are extracted out, close valve; High-low pressure is spaced apart, assurance operating personnel's safety.
