Summary of the invention
The purpose of this utility model provides a kind of easy to use and can guarantee two on-load switch interlocks of two on-load switch interlockings.
For achieving the above object, the utility model adopts following technical scheme: two on-load switch interlocks, comprise left bottom plate, right base plate, the big connecting lever in a left side, right big connecting lever, the little connecting lever in a left side, right little connecting lever, last long draw, following long draw, left side short rod, right short rod, left side shield, right shield, it is characterized in that left bottom plate and right base plate are separately fixed in two adjacent loading switch cabinets of the left and right sides, the bottom of left bottom plate is provided with the left-handed opening handle hole, the top of right base plate is provided with right switching manipulation hole, left side shield axle and left little connecting lever axle are separately fixed on the left bottom plate, right shield axle and right little connecting lever axle are separately fixed on the right base plate, one end of left side shield is enclosed within on the left shield axle, one end of right shield is enclosed within on the right shield axle, one end of the little connecting lever in a left side is enclosed within on the left little connecting lever axle, one end of right little connecting lever is enclosed within on the right little connecting lever axle, one end of the big connecting lever in a left side is fixedlyed connected with the left on-load switch main shaft that passes left bottom plate, the other end of the big connecting lever in a left side links to each other with the left end of last long draw, the right-hand member of last long draw links to each other with the little connecting lever in the right side, the two ends of right short rod link to each other with right little connecting lever with right shield respectively, one end of right big connecting lever is fixedlyed connected with the right on-load switch main shaft that passes right base plate, the other end of right big connecting lever links to each other with the right-hand member of following long draw, the left end of following long draw links to each other with the little connecting lever in a left side, and the two ends of left short rod link to each other with left little connecting lever with left shield respectively.
Because the utility model transmits displacement by drag link mechanism, and is simple and reliable, therefore can not only guarantee two on-load switch interlockings, and also very easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is for the utility model left side on-load switch is in combined floodgate, right on-load switch is in the gate-dividing state schematic diagram;
Fig. 3 is for the right on-load switch of the utility model is in combined floodgate, left on-load switch is in the gate-dividing state schematic diagram.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described, but this embodiment should not be construed as restriction of the present utility model.
The utility model comprises left bottom plate 1, right base plate 2, the big connecting lever 3 in a left side, right big connecting lever 4, the little connecting lever 5 in a left side, right little connecting lever 6, last long draw 7, following long draw 8, left side short rod 9, right short rod 10, left side shield 11, right shield 12, it is characterized in that left bottom plate 1 and right base plate 2 are separately fixed in two adjacent loading switch cabinets of the left and right sides, the bottom of left bottom plate 1 is provided with left-handed opening handle hole 13, the top of right base plate 2 is provided with right switching manipulation hole 14, left side shield axle 15 and left little connecting lever axle 17 are separately fixed on the left bottom plate 1, right shield axle 16 and right little connecting lever axle 18 are separately fixed on the right base plate 2, one end of left side shield 11 is enclosed within on the left shield axle 15, one end of right shield 12 is enclosed within on the right shield axle 16, one end of the little connecting lever 5 in a left side is enclosed within on the left little connecting lever axle 17, one end of right little connecting lever 6 is enclosed within on the right little connecting lever axle 18, one end of the big connecting lever 3 in a left side is fixedlyed connected with the left on-load switch main shaft that passes left bottom plate 1, the other end of the big connecting lever 3 in a left side links to each other with the left end of last long draw 7, the right-hand member of last long draw 7 links to each other with the little connecting lever 6 in the right side, the two ends of right short rod 10 link to each other with right little connecting lever 6 with right shield 12 respectively, one end of right big connecting lever 4 is fixedlyed connected with the right on-load switch main shaft that passes right base plate 2, the other end of right big connecting lever 4 links to each other with the right-hand member of following long draw 8, the left end of following long draw 8 links to each other with the little connecting lever 5 in a left side, and the two ends of left short rod 9 link to each other with left little connecting lever 5 with left shield 11 respectively.
