Description
Technical field
The present invention relates to power construction field, particularly a kind of variable arm lever for connecting cable.
Background technology
In power construction, generally can install metal sleeve in order to support and fixing from cable trough to power equipment, the electric power cable of mechanism case, terminal box.Metal tube can effectively avoid cable by cattle grazing, external environment condition corrosion and physical damnification.This mode has feature safe and reliable, succinctly attractive in appearance, so be widely used in the middle of power equipment out of doors.
Cable from metal tube out access arrangement, mechanism case or when intersecting with it metal tube to another root cable have certain bending.In working at the scene, the degree of crook (crooked radian) of cable is larger or cable is more thick harder, cable to connect difficulty of construction larger, engineering time also can correspondingly increase, in addition the insulating barrier of cable surface is easily scratched, particularly aloft operation time increase worker's difficulty of construction, time, danger coefficient especially, and pole consumes one's strength.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of variable arm lever for connecting cable, can realize connecting fast of cable, and avoid the destruction to cable insulation in threading procedure.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of variable arm lever for connecting cable, comprise main body, connecting rod, force application rod and lever, be uniformly distributed around main body and be provided with at least two connecting rods, multiple connecting rod is respectively equipped with the force application rod vertical with connecting rod, main body is also provided with lever.
In preferred scheme, on described lever, cover is equipped with lever sleeve pipe, and lever sleeve pipe is provided with the first fixed via, and the first set bolt is through the first fixed via, and lever holds out against fixing by one end that the first set bolt is positioned at lever inside pipe casing.
In preferred scheme, described connecting rod is provided with longitudinal chute, and force application rod top is provided with guide vane end stop, and force application rod also can slide along chute direction through chute.
In preferred scheme, described connecting rod is also provided with horizontal fixing fluting, force application rod is provided with the second fixed via with the position of fixing same level of slot, and the second set bolt passes after the fixing fluting of the fixing fluting of connecting rod side, the second fixed via and connecting rod opposite side successively by being fixed on connecting rod by force application rod with nut check.
In preferred scheme, described force application rod is provided with spacing ball away from one end of connecting rod.
This novel provided a kind of variable arm lever for connecting cable, by adopting said structure, has following beneficial effect:
(1) adopt lever principle, utilize the mode increasing the arm of force, increase the angle between adjusting sleeve pipe and cable, make adjustment process more light, and more quick, compared to the mode that original violence connects, cable insulating barrier can be avoided to be destroyed;
(2) spacing between force application rod and main body can free adjustment, can carry out regulating the spacing between force application rod and main body for the cable length be exposed at outward outside two joint sleeve pipes, ensure force application rod can with cable close contact;
(3) lever length can regulate, lever length is longer, the required power applied is less, but long lever easily causes device volume too large, storage is inconvenient, and the too short power needing to apply of lever is comparatively large, adds the amount of labour in threading procedure, adopt the length lever that can regulate, the whole device not only amount of labour that connects in work of convenient for collecting but also can reduce can be ensured.
Adopt said structure, what achieve cable connects work fast, avoids in threading procedure, and sleeve pipe, to the destruction of cable insulation, decreases simultaneously and connects the required time, improve and connect operating efficiency.
