At the angle deflection fastening structure 672 is equipped with more than two and equidistant respectively following tables for being welded on bending buckling plate 671 altogether
Face, it is described bending buckling plate 671 be welded on fasten 66 lower surface of snap-gauge center, be bent buckling plate 671 outer shape with
The outer shape of optical cable is corresponding, and angle deflection fastening structure 672 prevents optical cable forced-slip, further stuck to optical cable.
Referring to Fig. 8, the pressure difference eject liquid structure 271 with rotary table 2711, lead channel 2712, straight-bar 2713,
Pressure-bearing hole 2714, reset spring 2715, indent small circular plate 2716, small lugs 2717 form, 2711 glue connection of cooperation rotary table
In the lower end of straight-bar 2713, upper end of the lead channel 2712 inside cooperation rotary table 2711, the pressure-bearing hole 2714 is embedded in
The inside of straight-bar 2713, the reset spring 2715 is around the outer ring for being connected to 2713 upper end of straight-bar, the indent small circular plate
2716 are welded on the upper end of straight-bar 2713, and the small lugs 2717 are equipped with more than two and equidistant respectively glue connections in indent altogether
The upper surface of small circular plate 2716, the small structure in the big centre in the both sides of lead channel 2712, makes lubricating fluid when pouring in bigger
Pressure improves flowing velocity, and indent small circular plate 2716 is corresponding with the outer shape of rolling friction ball 274, reduces between the two
Friction and reduce the pressure of unit area receiving, small lugs 2717 make between indent small circular plate 2716 and rolling friction ball 274
It is attached on rolling friction ball 274 with certain gap convenient for the ejection of lubricating fluid.
Referring to Fig. 9, the angle deflection fastening structure 672 in the bending 671 lower surface middle section of buckling plate is by oblique pointed tooth
6721, it is biased to spine 6722 to form, the left end be biased to spine 6722 and be welded on oblique pointed tooth 6721, the oblique pointed tooth
6721 are welded on the lower surface of bending buckling plate 671, and the length of oblique pointed tooth 6721 is less than the thickness of optical cable epidermis, prevents epidermis
It is punctured, the lower end of oblique pointed tooth 6721 is to right avertence, and the tension direction with optical cable is on the contrary, convenient for consolidating optical cable in optical cable stress
It lives calmly, further fix can be provided optical cable by being biased to spine 6722.
At work, one end of optical cable is placed on the lower hollow out card in spine backward-acting power escapement 6 by operator
On plate 64, then cover and fasten snap-gauge 66, screwing screw 65, make oblique pointed tooth 6721 in acting in opposition anti-skid structure 67 with
It is biased to spine 6722 to be inserted into the epidermis of optical cable, then covers upper half closing disk 4, drag rope is tied up and squeezed in rolling by screwing bolts 3
It presses on the bail 23 in antiseize mechanism 2, before being drawn to optical cable, lubricating fluid is injected from inlet 22, makes to moisten
Synovia chamber 26 is full of lubricating fluid, and air bag 25 is deformed, after 26 internal pressure of lubricating fluid chamber reaches a certain level, profit
Then stopping when synovia can not be further continued for being filled with draws optical cable using pulling equipment, class ball end 21 and other
Optical cable or inner wall of the pipe contact, make rolling friction ball 274 in the longitudinal stress discharging liquid by extruding structure 27 of internal outmost turns by
To extruding, rolling friction ball 274 is moved down, and so that pressure difference is ejected liquid structure 271 and is moved down, then cooperate rotary table 2711 with
The inner wall of lubricating fluid chamber 26 separates, and lubricating fluid enters lubricating fluid from lead channel 2712 due to the deformation power by air bag 25
To pressure-bearing hole 2714, on being ejected into rolling friction ball 274,274 surface of rolling friction ball is made to adhere to lubricating fluid, rolling friction ball
274 contact with inner wall of the pipe and other optical cables, and lubricating fluid is made indirectly to be attached to the surface of inner wall of the pipe He other optical cables, class circle
The running track of ball end 21 is exactly the running track of target optical cable, target optical cable in distraction procedure will not by card plug,
To complete work.
The present invention is combined with each other by above-mentioned component, and pressure difference ejects liquid structure 271 and rolling friction ball 274 mutually matches
It closes, so that class ball end 21 is squeezed in sliding process and is slowly sprayed lubricating fluid, make to be attached with profit on operating path
Synovia prevents stucking phenomena convenient for the operation of target optical cable, reduces frictional force suffered by target optical cable, keeps frictional force small
In the tension limit of optical cable, cable core is protected, upper fastening snap-gauge 66 is worked in coordination with acting in opposition anti-skid structure 67, in target optical cable
It when by frictional force, prevents optical cable from falling off in distraction procedure, makes to draw stable working completion.
Specific embodiment described herein is only to give an example to the present invention.
The present invention is not limited to above-mentioned preferred forms, and anyone should learn that the knots made under the inspiration of the present invention
Structure variation, the technical schemes that are same or similar to the present invention are fallen within protection scope of the present invention.
