Description

A kind of cable peeling knife

Technical field

The utility model relates to a kind of electric power overhaul tool, especially a kind of cable peeling knife.

Background technique

Currently, in the links of power generation, such as during the construction of substation, transformation, it is often necessary to cable Peeling processing is carried out, however lacks a kind of cutter for being suitble to this to work on the market.Under common situation, operator utilizes wallpaper Knife completes this work, in peeling process, does not pay attention to that slightly operator will be damaged, and the bad grasp of dynamics, Overexert the metal core that can be cut inside cable, and since cable sheath has very strong hardness, it is often necessary to cut repeatedly Repeatedly can just it succeed, waste of time.

Utility model content

The technical assignment of the utility model is to be directed to the above the deficiencies in the prior art, and provide a kind of cable peeling knife.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of cable peeling knife, including two The annular runner of a same size, on a wherein runner be equipped with annular sliding slot, on another runner be equipped with it is described The sliding block of sliding slot cooperation, one of runner are to determine ring, another runner is rotating ring, and it is recessed to be equipped with spiral in the inside of the rotating ring Slot is equipped with the first link block in the spiral groove, slideway is equipped on the radial direction determined on the inside of ring, in the cunning It is equipped with the second link block in road, passes through sliding knife connection between first link block and the second link block.

It is further improved: three spiral grooves is uniformly provided on the inside of the rotating ring, in the radius determined on the inside of ring Three slideways are correspondingly provided on direction.

It is further improved: being equipped with the backing plate of arc in the front end of the sliding knife, be equipped with idler wheel at the backing plate both ends.

The advantages of the utility model: it is gone to adjust the depth of sliding knife to meet different-diameter cable by rotation rotating ring The demand of skin, simultaneously because sliding knife is the safety for being arranged at the inner ring of runner, and then ensuring user, because cutting skin When, be by and meanwhile rotation determine ring and rotating ring and sliding knife driven to be rotated along the circumference of cable, the notch cut out in this way is just It is very neat.

Specific embodiment

The utility model is described below with reference to the accompanying drawings of the specification.

As shown, a kind of cable peeling knife, including the annular runner of two same sizes, a runner wherein It is equipped with the sliding slot 3 of annular, the sliding block 4 cooperated with the sliding slot 3 is equipped on another runner, one of runner is to determine ring 1, another runner is rotating ring 2, is equipped with spiral groove 5 in the inside of the rotating ring 2, first is equipped in the spiral groove 5 Link block 6 is equipped with slideway 8 on the radial direction for determining 1 inside of ring, the second link block 9 is equipped in the slideway 8, It is connected between first link block 6 and the second link block 9 by sliding knife 7.

Three spiral grooves 4 are uniformly provided in the inside of the rotating ring 2, it is right on the radial direction for determining 1 inside of ring Slideway 8 there are three should setting；It is equipped with the backing plate 71 of arc in the front end of the sliding knife 7, is equipped with idler wheel 72 at 71 both ends of backing plate.

Its working principle is that: the cable of peeling will be needed to penetrate in runner first, then rotate rotating ring 2, rotating ring 2 is rotating When, since the side of sliding knife 7 is to be connect by the second link block 9 with the slideway 8 determined on ring 1, so sliding knife 7 can only be along slideway 8 move on the radius for determining ring 1, in addition, since sliding knife 7 is connected in the spiral groove 5 of rotating ring 2 by the first link block 6, So rotating ring 2 is in rotation, the first link block 6 moves in spiral groove 5, passes through the common work of slideway 8 and spiral groove 5 With the purpose for adjusting sliding 7 point of a knife radius of action of knife being played when rotating rotating ring 2 in this way, therefore meet different-diameter cable Peeling demand.

It after the radius of sliding knife 7 is adjusted, while holding rotating ring 2 and determining ring 1, then rotate together and determine ring 1 and rotating ring 2, Knife 7 sliding so circumferentially cuts the crust of cable, finally along the axis direction of cable, pulls together determine 1 He of ring outward Rotating ring 2, knife 7 sliding in this way cut the crust of cable along the axis of cable, this process is easy to operate, can not only The cable of different-diameter is enough adapted to, but also ensures the safety of operator well.

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in Other related technical areas are also included in the patent protection scope of the utility model.
