Embodiment
With reference to specific embodiment, the invention will be further described, the illustrative examples and explanation invented herein
For explaining the present invention, but it is not as a limitation of the invention.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of lv contactor, including column 1, hydraulic cylinder 2, worm screw 3, circular bottom plate
7.The center of circular bottom plate 7 is provided with sleeve 701, and three 702, three group first of supports are also equipped with above circular bottom plate 7
704, three osculating elements of bearing pin 703 and three group of second bearing pin, each group of the first bearing pin includes two the first bearing pins 703, each
The second bearing pin of group includes two the second bearing pins 704, and two the second bearing pins 704 are symmetrically mounted on two outsides of the first bearing pin 703, circle
Shape bottom plate 7 is made using insulating materials.
Each osculating element includes worm gear 4, connecting rod 5,8, two, the roller of travelling carriage 6, two helical spring 9, two and swung
10, two, bar, 12, one group first of retainer, 703, one group second of the bearing pin bearing pin 704 of binding post 11, two, worm gear 4 rotate peace
On support 702, a pin is provided with the side of worm gear 4, the one end of connecting rod 5 is hingedly mounted on pin, and the other end is with sliding
The rearward end of frame 6 is articulated and connected, and the front end of travelling carriage 6 is Y-shaped structure, and peace turns have two rollers 8 in the Liang Ge branches of Y-shaped structure,
