Abstract

The utility model relates to an optical cable peeling knife, which is a tool used for peeling off the outer coating and the inner aluminum armoring of the fiber cable or to further cut the central tube. The utility model takes the tube body with a breach in the middle as its main body. The optical cable line bayonet is composed of a fixing seat and a telescopic active seat arranged on the two sides of the breach, or is composed of two pairs of sliding wheels arranged on the fixing seat and active seat. One end of the knife carrier runs through the fixing seat and makes the blade extend into the breach, while the other end of the knife carrier links with the driving and reversing nut to axially adjust the blade driving depth. The active seat on the other side of the breach is connected with a push bar to axially push forward and reset by a return button. The blade angle can be adjusted by a motion button to choose the direction to peel off the cable line in longitudinal, radial or helix direction. The utility model has the advantages of easy operation, powerful cutting and labor saving.

Description

The optical cable baring cutter

Technical field

The utility model relates to the optical cable baring cutter, is that the fiber optic cables construction time is used for outer epidermis, the unlined aluminium armour of stripping fiber optic cables or further severs the instrument of center beam tube.

Background technology

In recent years, fiber optic communication has been widely used in private wire networks such as public network such as city relaying, long-distance call and submarine communication and railway, electric power, is applied in public telephone, broadcasting and computer private network simultaneously.Lightguide cable link is the important component part of communication system, often need open stripping to cable line in the newly-built and maintenance construction of optical cable communication network.The outer foreskin of cable line is thicker, and the unlined aluminium armour is comparatively hard, opens difficulty of stripping, and present various optical cable baring instrument results of use are all not really desirable.A kind of formula blade that colludes, with the outer skin of blade penetration and catch on the internal layer armor, utilize subsequently leverage rotate that ratchet-gear wheel drives that blade moves to right and and vertically cut epidermis, comparatively require great effort during operation.Another kind is the Straight pull blade, behind the outer inside of blade incision optical cable, exerts all one's effort vertical pulling by both hands, with the epidermis strip off, be used for the minor diameter optical cable still can, the major diameter optical cable now then is difficult for pulling.More than collude the formula cutter, straight formula cutter can only be used for vertically opening stripping, can not radially open stripping, operation is effort very, and uses inconveniently, it is low to open the stripping operating efficiency.Other has a kind of double-pole formula, but complex structure, heaviness is carried inconvenience.

Summary of the invention

The purpose of this utility model provides a kind of easy to use, rapid operation, small-sized, portable optical cable baring cutter.

The utility model optical cable baring cutter comprises body, knife bar, blade and cable line bayonet socket, said body is the tubular body that there is a gap at the middle part, the cable line bayonet socket is made up of holder that is contained in the gap both sides and telescopic sliding seat, one end of knife bar runs through holder, the blade of its end stretches into gap, and the knife bar other end links to each other and interlock with it with an advance and retreat nut; Said sliding seat links to each other with a push rod and can be with the push rod axial advance, and push rod is provided with the return button.

In addition, originally drive broach and also comprise following feature:

The holder of gap both sides and sliding seat are equipped with a pair of pulley respectively, form the cable line bayonet socket by these two pairs of pulleys.

Said knife bar is connected with one and turns to toggle, by stirring toggle, can make blade be in horizontal, vertical or oblique position.

The scale that shows the feed distance is carved with on said advance and retreat nut surface.

This optical cable baring cutter clamps cable line by the holder and the sliding seat (or pulley of both sides) of gap both sides, with toggle blade is allocated to required direction, by rotation, making the advance and retreat nut drive knife bar advances to the gap direction, point of a knife is stretched into cable line epidermis certain depth, with this optical cable baring cutter along cable line vertically or circumferencial direction move, can be vertically or the hand of spiral with the cable line strip off.This cutter is easy to operate, and cutting force is big, and is laborsaving, and same open broach can select to cable line adopt radially, axially or the spirality direction open stripping.As bayonet socket, the friction between broach and the cable line is reduced with the pulley of gap both sides, operate more laborsaving.

The specific embodiment

Below in conjunction with description of drawings example structure of the present utility model.

Fig. 1 and Fig. 2 represent cable line 12 gap 2 by clip in the two pairs of

pulleys

7 and 7 of both sides ' between, the two pairs of pulleys 7 and 7 ' respectively are loaded on holder 5 and the sliding seat 4, sliding seat advances to gap 2 directions by push rod 9, so that a pair of pulley 7 ' push cable line 12 to make cable line 12 by mounting board.Blade 10 among Fig. 2 be by turn nut 6 to cable line 12 feeds, the direction of blade 10 is determined by stirring toggle 3.Fig. 3 represents that blade 10 links to each other with advance and retreat nut 6 by knife bar 11, axially advances and retreat with the rotation of nut 6, and the distance of advance and retreat can be determined by figure 6-1 preliminary election.

When Fig. 4～Fig. 6 represented to be allocated to three kinds of diverse locations by toggle 3 respectively, blade 10 was transferred to horizontal position, oblique position or vertical position respectively.

This cutter to open stripping operation as follows: cable line such as Fig. 1 are put into gap 2 and are pushed sliding seat to gap 2 by push rod 9, make cable line 12 by mounting board in two groups of pulleys 7,7 ' between; With blade 10 transfer to as Fig. 4 to transverse presentation and by advance and retreat nut 6 make blade 10 stretch into the cable line epidermis.Hold body 1, it is rotated a circle around cable line, the cable line epidermis is promptly radially cut, and subsequently toggle is stirred the oblique position of blade such as Fig. 5, keeps and rotates around cable line, and then the cable line epidermis is very fast by the spirality strip off.As intend axial stripping fiber optic cables line, and then only needing with the vertical position that blade 10 is transferred to as Fig. 6, both hands are held out the both sides of broach, and along moving axially of cable line, cable line is promptly by axially strip off.Open the stripping finish after, press return button 8, can make push rod 9 return original position, bayonet socket promptly unclamps.
