Description

The cross-linked power cable wire stripper

One. technical field: the utility model relates to a kind of wire stripping pliers, particularly relates to a kind of cross-linked power cable wire stripper.

Two. background technology: present existing cross-linked power cable insulating barrier stripping and cutting tool has multiple, is a kind of stripping and cutting tool that adopts circular knife rotary-cut cable insulation such as a kind of Italian cable insulation stripping and cutting tool, can peel cable insulation preferably off.Its shortcoming is an inefficiency, and promptly the cutter track route is very long in the certain length range of the cable that will cut, like this, resistance was bigger when clamping device moved at multi-circle spiral flow, might damage the stripping cable surface, reduce friction complex operation so need splash into lubricant.It is too much that the stripping and cutting tool that has is in addition adjusted link, is not suitable for on-the-spot practical operation; The function singleness that has has only the ring cutting function, and perhaps crosscut function needs several instruments to be used in combination or the like when the stripping cable.

Three. the utility model content:

Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, the cross-linked power cable wire stripper of the many and high efficiency of a kind of reasonable in design, easy to use, function is provided.

The technical solution of the utility model is: a kind of cross-linked power cable wire stripper, contain pincers handle and lower clamp handle, the two is hinged by hinge, the described front end jaw that clamps handle of going up is provided with pincers Hubei Province plate, and the front end jaw of described lower clamp handle is provided with the olecranon hook, and clamp being provided with knife rest at described rear portion of going up the pincers handle, this knife rest is provided with blade, the rear portion pincers of described lower clamp handle are being provided with wheel carrier, and described wheel carrier is corresponding with described knife rest, on the described wheel carrier pinch roller is installed; Be provided with spring between described knife rest and the last pincers handle, be provided with slideway and slide block between described wheel carrier and the lower clamp handle, described slide block lower end is corresponding with the diameter adjustment knob.

Described pinch roller has two and setting at interval.Described going up between pincers handle and the lower clamp handle is provided with dog screw; The described pincers of going up are being provided with location notch, and described knife rest is arranged in this location notch.

The beneficial effects of the utility model are:

1, the utility model can carry out stripping to cable insulation preferably; can be in same whole stripping processes of finishing cable insulation that stripping is clamped; high efficiency; and can protect near the undressed cable surface of otch in good condition; particularly in multiple cable size scope (as φ 20～φ 40) when carrying out stripping; blade all is adjustable to desirable cutting position; be that cut point is on the symmetrical center line of two pinch rollers; therefore very laborsaving when cutting cables with different diameters insulating barrier, " dead point " phenomenon can not appear.

2, the utility model is provided with the diameter adjustment knob, can carry out the insulating barrier stripping to the power cable of different-diameter, and, also be provided with dog screw, can control the stripping degree of depth effectively, prevent that the stripping degree of depth is not enough or the stripping degree of depth is dark excessively.

3, the utility model knife rest can rotate, can ring cutting, again can crosscut, and usefulness more than one, in addition, knife rest can not drop out fixing in location notch under the holding out against of spring.

4, the utility model lower clamp handle front end is provided with the olecranon hook, and hook the insulating barrier otch of cross section effectively, is convenient to peel off insulating barrier.

5, the utility model is reasonable in design, easy to use, function many and high efficiency, be widely used in the important process of civilian and industrial power construction and maintenance, repairing, especially in the electric power first-aid course of work, the speed of stripping cable insulation and stripping quality, directly have influence on the efficient and the people's livelihood major issue of electric power first-aid work, have good economic benefit after the popularization.

Five. embodiment:

Embodiment: referring to Fig. 1-Fig. 5, among the figure, 1-lower clamp handle, the last pincers handle of 2-, 3-slide block, 4-pinch roller, 5-blade, 6-knife rest, 7-knife rest bar, 8-spring, 9-hinge, 10-olecranon hook, 11-workpiece, 12-pincers Hubei Province plate, 13-dog screw, 14-diameter adjustment knob.

The cross-linked power cable wire stripper contains pincers 2 and lower clamp handle 1, the two is hinged by hinge 9, last pincers are provided with pincers Hubei Province plate 12 to 2 front end jaw, the front end jaw of lower clamp handle 1 is provided with olecranon hook 10, last pincers clamp 2 rear portion being provided with knife rest 6, this knife rest 6 is provided with blade 5, knife rest 6 upper ends are knife rest bar 7, knife rest bar 7 and last pincers are provided with spring 8 between 2, the rear portion pincers of lower clamp handle 1 are being provided with wheel carrier, two pinch rollers 4 are installed on the wheel carrier, are provided with slideway and slide block 3 between wheel carrier and the lower clamp handle 1, slide block 3 lower ends are corresponding with diameter adjustment knob 14.Last pincers 2 and lower clamp handle 1 between be provided with dog screw 13; Last pincers are provided with location notch to 2, and knife rest 6 is arranged in this location notch.

Knife rest 6 upper ends are knife rest bars 7, knife rest bar 7 can rotate in 2 hole at last pincers, spring 8 is contained in pincers in 2 the counterbore, withstand knife rest 6 and be bumped into pincers in 2 the location notch, diameter adjustment knob 14 is contained in the screw of slide block 3, during rotating diameter adjusting knob 14, slide block 3 moves up and down, and two pinch rollers 4 are used for workpiece pressing 11.Regulate the shoulder that dog screw 13 withstands lower clamp handle 1 olecranon hook 10, can limit and clamp 2 and lower clamp handle 1 final position of depressing.

Operation principle:

Adjust diameter adjustment knob 14 before the stripping cable insulation earlier, the stripping pincers are adapted to want the diameter of processing cable workpiece 11, and adjust the distance of dog screw 13 and olecranon hook 10 shoulders, i.e. Qie Ge the degree of depth, as shown in Figure 2.

In step stripping cable insulation time-division three, the first step is carried out ring cutting, clutches pincers 2 and lower clamp handle 1, makes blade 5 cut insulating barriers, and dog screw 13 is spacing at this moment, rotates stripping then and clamps a week, finishes the ring cutting operation to cable insulation, as shown in Figure 3.

Second step, carry out crosscut, rotating knife hack lever 7 makes blade 5 on the knife rest 6 be parallel to the axis of cable workpiece, and this moment, the effect of spring 8 was to hold out against knife rest 6 can not drop out in location notch.Clutch pincers then 2 and lower clamp handle 1, make blade 5 be pressed into cable insulation, and operate several times, reach the purpose of whole crosscuts, as shown in Figure 4 according to the length branch of want stripping.

The 3rd step, carry out horizontal stripping, workpiece 11 is placed on olecranon hook 10 and pincers plate 12 places, Hubei Province, make olecranon hook 10 aim at transverse incisions, clutch and clamp 2 and lower clamp handle 1, can peel cable insulation, finish stripping work, as shown in Figure 5.
