Embodiment
Below in conjunction with the drawings and specific embodiments, technical solutions of the utility model are described in detail, further to understand the purpose of this utility model, scheme and effect, but and are not used to limit the utility model.
Please refer to Fig. 1 and Fig. 2, Fig. 1 is the front view of the utility model lever automatic earthing electric installation structure; Fig. 2 is the end view of the utility model lever automatic earthing electric installation structure.Holder 1 makes for circular steel plate and is installed on turning rolls 6 by four hexagon socket head cap screws 11; Lever 2 makes for channel-section steel and is connected to holder 1 by a bearing pin 21; Bearing pin 21 to make and one end is connected to holder 1 for round steel, and the other end is set with a flat shim 22, and is installed on nut 23 fastening lever 2 outside flat shim 22 by one, and lever 2 can be axle flexible rotating with bearing pin 21; Bearing pin 21 is also set with a seamless steel pipe 24 with the junction of lever 2, and is connected to lever 2; Conducting rotary plate 3 makes for circular steel plate and is connected to lever 2 by another bearing pin 31; Bearing pin 31 to make and one end is connected to one end of lever 2 for round steel, and the other end is set with a flat shim 32, and is installed on the fastening conducting rotary plate 3 of nut 33 outside flat shim 32 by one, and conducting rotary plate 3 can be axle flexible rotating with bearing pin 31; Balancing weight 4 makes for steel plate and is installed on the other end of lever 2.
