What handle of a knife, leading plate, lead one, lead two, fast pulley, spreader, leading groove, lower drawstring and upper drawstring formed, it is described solid
The surrounding of fixed board is provided with location hole, and plug-in strip is provided with the left of the fixed plate, and the plug-in strip handle is fixedly connected with spreader, institute
The centre position that leading plate is arranged on fixed plate is stated, leading groove is provided with the leading plate, the upper end of the leading plate is set
There are lead one and lead two, the lead one is arranged on the top of lead two, and lead one is located at lead two
Outside, spreader and the leading groove coordinate, and fast pulley is provided with the spreader, and the fast pulley is located at the outside of leading plate,
For the upper drawstring one ends wound on fast pulley, upper drawstring first passes around lead two, further around lead one is crossed, is bonded fixed plate
Surface naturally droops, and described lower drawstring one end, which is fixed, to be wrapped on fast pulley, and the rope body of lower drawstring naturally droops.
Further, the spreader is metal material.
Further, it is equipped with fixed pulley on the lead one and lead two.
The usefulness of the utility model is, when progress family expenses circuit falls lock and closes a floodgate, only to pass through pull-up in lower section
Rope and lower drawstring can be operated, it is not necessary to operated by other media, avoid the generation of electric shock event, together
When the apparatus structure it is ingenious, service life is longer, is easily installed and fixes, and upper drawstring and lower drawstring are conveniently replaceable.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the device；
Fig. 2 is the structure diagram after the upper drawstring of device removal and lower drawstring.
In figure, 1, fixed plate, 2, location hole, 3, plug-in strip handle, 4, leading plate, 5, lead one, 6, lead two, 7, fixed
Wheel, 8, spreader, 9, leading groove, 10, lower drawstring, 11, upper drawstring.
Embodiment
A kind of knife switch, be by fixed plate 1, location hole 2, plug-in strip handle 3, leading plate 4, lead 1, lead 26,
What fast pulley 7, spreader 8, leading groove 9, lower drawstring 10 and upper drawstring 11 formed, the surrounding of the fixed plate 1 is provided with location hole
2, the left side of the fixed plate 1 is provided with plug-in strip, and the plug-in strip handle 3 is fixedly connected with spreader 8, and the leading plate 4 is arranged on solid
The centre position of fixed board 7, is provided with leading groove 9 on the leading plate 4, the upper end of the leading plate 4 is provided with one 5 He of lead
Lead 26, the lead 1 are arranged on the top of lead 26, and lead 1 is located at the outside of lead 26, institute
State spreader 8 and leading groove 9 coordinates, fast pulley 7 is provided with the spreader 8, the fast pulley 7 is located at the outside of leading plate 4, institute
11 one ends wound of drawstring is stated on fast pulley 7, upper drawstring 11 first passes around lead 26, further around lead 1 is crossed, is bonded
1 surface of fixed plate naturally droops, and described lower 10 one end of drawstring, which is fixed, to be wrapped on fast pulley 7, under the rope body nature of lower drawstring 10
Hang down.
Further, the spreader 8 is metal material, helps to improve use intensity and service life.
Further, fixed pulley is equipped with the lead 1 and lead 26, can effectively reduces pull-up
Rope and the lower received friction of drawstring.
